In 2122, a Weyland-Yutani starfreighter registered as the Nostromo detected and partially decoded
an unidentified signal originating from LV-426, a desolate and largely ignored planet.
A team sent to uncover the source of the signal discovered the remains of a derelict spacecraft,
almost certainly alien in origin.
While compelled to investigate further by Weyland-Yutani regulations, the true nature
of the signal was discovered far too late: it was not an SOS, but a warning.
In the ensuing hours, the seven-man crew of the Nostromo was torn apart by a creature
whose structural perfection was matched only by its hostility.
When every means to combat this "xenomorph" was exhausted, the Nostromo was set to self destruct.
The light shuttle Narcissus escaped with a sole survivor, Ellen Louise Ripley.
30 years old at the time of the Nostromo incident, Ripley was already an experienced warrant
officer having served on a variety of ships in the United Americas merchant navy.
Prior to her final voyage aboard the Nostromo, Ripley had renegotiated her contract with
Weyland-Yutani, intending to take an extended leave to spend more time with her daughter Amanda.
Instead, the Narcissus drifted for fifty-seven years straight through the core systems of
the network until she was picked up by chance by a deep space salvage team.
When she awoke, her report on the events that led to the destruction of the Nostromo was
met with skepticism.
Amanda had died years earlier and this news, combined with her experiences, left her diagnosed
with a variety of post-traumatic and comorbid stress disorders.
Her career stripped away and her warnings over the dangers of LV-426 ignored, Ripley
relocated to Earth, securing employment as a Power Loader operator.
When contact with Hadley's Hope, a terraforming colony on LV-426 was severed, Ripley was approached
by the United States Colonial Marine Corps to serve as an advisor on a mission to ascertain
the status of the colony.
When they arrived, Hadley's Hope appeared deserted, but Ripley's worst fears were
realized when xenomorphs of the same type encountered on the Nostromo were discovered
in far greater numbers.
Despite the marine's overwhelming firepower, they were far too few to make any difference.
Together with Rebecca Jorden, better known as "Newt", Ripley attempted to aid the
marines as best she could as they were set upon by Xenomorphs, before retreating to the
orbiting USS Sulaco.
A xenomorph queen, first encountered within the colony's Atmosphere Processor, had latched
onto their dropship however, and it was only through Ripley's expertise in the Power
Loader that herself, Newt and Senior Corporal Dwayne Hicks were spared and the queen destroyed.
In a cruel repetition of fate, the Sulaco crashed on Fiorina 161 and Ripley was again
the sole survivor.
A former commercial mining venture, the planet had been repurposed to serve as a penal labor
colony for particularly dangerous inmates.
After repairing the remains of Bishop, an android originally in service aboard the Sulaco,
Ripley discovered that a xenomorph had been responsible for their crash landing, and likely
present somewhere within the Correctional Facility.
The deaths of multiple inmates confirmed the creature's existence and the inmates of
Fiorina turned to Ripley for leadership, once her previous expertise had been revealed.
However, Ripley had begun to suffer mysterious physical ailments since arriving on the planet,
and she soon realized that one of the creatures was maturing inside her.
After the roaming xenomorph was finally destroyed, Ripley was approached by a team of scientists
and commandos under the authority of Weyland-Yutani.
Despite their assurances that they could save her life, Ripley understood that their only
goal was to study and exploit the creature within her.
Desperate to prevent anyone else from sharing her fate, Ripley threw herself into a furnace,
ensuring the extinction of the xenomorph species.
The horrific events suffered by Ripley traumatized her greatly, but her defining aspect was the
immeasurable will and perseverance she displayed in dealing with tragedy and adversity.
Even before her encounter aboard the Nostromo, Ripley was a professional, capable of maintaining
a calm focus and executing orders in even the most dangerous situations.
She possessed an enormous moral fortitude, routinely risking her own life to ensure the
safety of others.
Ripley held little tolerance for those she deemed untrustworthy or incapable of decisive action.
When the situation required it, she would quickly take command rather than waiting for
permission or orders.
While her encounters with the xenomorphs left her colder and more apathetic towards her
own life, she never lost her compassion or sense of honor.
Through her sacrifice, humanity was saved from the worst aspects of its own nature,
but perhaps, only for a time.

Battery Solutions for Powering Sony Mirrorless and DSLR's - Duration: 10:20.
Are you trying to run your camera with these we do the batteries?
Send my battery solutions here on the slanted lens blow for dslr's and for Sony mirrorless by any Pro
Check it out. Next on slanted lens
Hi, this is JP Morgan today on slanted lens we're gonna talk about battery solutions for DSLRs and for Sony mirrorless cameras
Why are we talking about this because it's a constant frustration for me on set. I like using DSLRs
I like using the Sony mirrorless sunset as a cinema camera solution
But the battery solution has never been as effective as the cameras were when you're working on sets
So there's a couple of things I came up with first off the sony a7r 2 battery was just it impossible
Impossible that one didn't work for five minutes. It wasn't worth the time took to put it into the camera
It really wasn't the new battery from Sony is much better
This gives us a lot more time on camera, but it still ends up
I'm about to the point where I want to continue in my interview. It's going great
The battery's getting close and now I start thinking about do I have enough battery time?
Do I have enough and it just gets frustrating? I don't like that one either. These are good batteries
Don't get me wrong. If you're doing still photography. These will shoot all day long
Well may not quite all day long, but they'll shoot a long long time
But if you're doing cinema and you got a screen going and you're shooting video, these are just not a good solution
need something else
So I've turned to more of a cinema solution to run my DSLR cameras for a couple of reasons
these 98 watt batteries are perfect for traveling because you can carry them onto the airplane with you and they don't harass you and you
Got plenty of battery solution when you get to the location
So here's how I'm using these things and there's several different ways to attach them to the camera
to attach them to the light stands are the things you're working on to be able to power these cameras in any
situation that they're in
number one simply an AC power supply
That has a dummy battery you plug this in the back of your camera plug this into the wall
And you now have power all day long?
Which is a great solution if you're standing right next to power all day long. It is not a great time lapse solution
there's not a solution if you're on set and you want to be moving your camera all around but if you're gonna set up and
do an interview and talk to someone for several hours or for a couple hours or something a
power solution is not a bad way to go plug it in and use it if I put a camera over head and
I don't want to have to touch it and I use cameras overhead like right now a lot
Then an AC power supply is a great way to go
You can power your camera not have to worry about ever having to touch it and you can run it all day long now
I looked up online and there are some super cheap versions of this online like 60 bucks
beware, those are just not great long-term solutions get something that's going to last you a little while if you're not close to
A power supply then a great solution is a DTaP with a dummy battery that goes to your camera
They make these for Sony's they make these for canons
They make them for all the different cameras out there the nice thing about this
Is it now it hooks to this battery and you can take the camera anywhere you want?
So the problem is how do I hold this battery around and it's just it's a battery. It's too heavy
It's just hard to deal with there's a way to get this battery next to your camera and run it off from this DTaP cable
So this is a golden mount plate I've taken off from another light that I had
I had a couple of these laying around that's just really a holder for the battery
there's nothing electrical about it and I'm gonna put a quarter twenty female corner 20 on this plate and it's just got a
Adhesive on the back and I'm just gonna stick it right in this corner right here
I do not have enough faith in the mighty mount. So I'm gonna glue the heck out of this thing with
Superglue something to make sure that that is not going to go anywhere. I'm gonna let that dry now
So the goal here is to be able to hook this on to either a bogan clamp super clamp
What do we call these guys? So I'm just gonna simply take this as soon as this dries
I will have this on here now. I have a plate to be able to hold my battery and this will attach here and
That will clamp on to the boom. That's gonna hold my camera now
This becomes a feed to my camera so I can power my camera and here it is overhead. Let's take a look at it
It's just a simple
Cook that under plates I've now got my cable goes into my camera
I can turn this battery on that battery's gonna run that mark three overhead for a long long long long time
All right, take it away camera goes away
Yeah, that's not easy to do
If you don't want to do a DIY battery plate
Then the teletype makes this great dummy gold mount battery plate and they make it envy mount as well that has a stand mount
So hook that on to a stand and if you happen to have a D tap to dummy battery
you hook your D tap on the back of your
End of the camera and you're good to go so there's one by Intel attack
Nd Pro Tools also makes a battery plate with a dummy battery, but it's kind of quarter-twenty spot on the back of it
This is perfect because now that corner 20 can just simply go into this little stand little clamp that they have
and
That little clamp
Can hook it on to your stand now? You've got a dummy battery that goes right into your camera. You're good to go
Added bonus this nd Pro Tools gold mount quarter 20 plate
And it's kind of battery connected to it can also serve it's a dummy battery
Just simply unplug this out of your camera now. I've got a D tap on the side
Any cable that goes to any camera? I can hook up D tap on the side and this now becomes a dummy battery or I
Can hook it into two cameras and then two cameras off from the same battery added bonus
So let's talk about some cinema style solutions here
The number one and probably the cheapest if you own Sony l-series type batteries is this Sony l-series battery pack
This takes two sony l series batteries
Both of them have to be on then
This is a dummy battery that goes to it a7 r2 so it's a double rail system double rail system
All these cinema solutions are gonna run on a double rail system
Which means you hook this to the two rails and that's your power supplies
You can put it up. But if you want to get it out of the way, you put it down
You can hook it wherever you want
If you want to put it in the front you put on the front depends on where you want it
Most people put it towards the back, but that's a great solution
If you already have these sony l series batteries because it's a very inexpensive
Solution to be able to get power to your camera and these are gonna run a lot longer
These L series batteries come in a lot of different sizes
So a lot of different options is gonna make this run a long long time
Now if you have gold mount batteries like I do
then this is a great solution because this is a battery plate a gold mount plate and
This has a double rail system hooks onto the back of your camera right there
Tighten it down and you're ready to go
you can put this battery up out or
like I say you put it in front anywhere you want to put it but that now hooks my golden mount batteries go on to
The plate and this becomes a great solutions got the dummy battery that goes into the camera
They have these for the h7 r3 as well as the Mark threes and fours
I mean
There's just these kinds of cinema style
Solutions this I think is a really good solution
If you have a V mount battery or a gold mount battery
They come in both of those different plates so you can put on the back your camera, you know
It's swapping batteries out all the time, which is really my goal
That's why we're doing this now one of the problems about these batteries is that they're very slow to recharge
It takes several hours to get these things to recharge
That's why I'm excited about the fact that any probe came up with this super charger
This cuts the battery charging time
Will these 98 watt batteries down to like an hour and 15 minutes?
which is incredible because I think these can go as high as
Seven hours on some charger depend on the charger not all chargers are the same and get a very cheap charger and it'll take forever
to charge one of these batteries but where the super charger takes about an hour and 15 minutes do that 98 watt battery and
Also, this will make sure that your battery is not under charge. It'll make sure it's not overcharge
It will shut down automatically if the battery starts to overheat
The super charger is worth the money because it gets your batteries off the charging and back in a service a lot
Supercharger Andy pearl also makes a 16 point 8 volt 1 amp
wall charger
What I love about this is just the fact that I can throw this in my bag and I can charge my batteries and this
Is all I have this tiny little thing goes with thee the supercharger is fabulous
But it's big the big charger that puts 2 batteries on it is huge
This makes a very compact travel friendly way to charge your batteries when you're on location
I think that's a great solution but last of all a little bonus
And this is a little they call this an D
USB
Adapter the new nd Pro batteries already come with the USB not all of these gold mount batteries do a lot of my old batteries
do not plug this in you now have the ability to not only run your camera through the DTaP but also to
Charge your phone on that USB, which is a great option because there's so many apps that run my time-lapse that run different devices
I want to be able to charge my phone while I'm shooting with my camera great solution there
so there you have it some great solutions on how to run your camera both your DSLR or your mirrorless camera when you're out on
Location I believe if you're in a cinema style situation doing interviews doing doc style work
You need a longer battery type solution
You truly do something that's going to allow you to shoot a long time and not have to worry about battery
You don't want to have to be out on location trying to find power trying to deal with all that charger batteries
take a good-size battery that's going to hook to your cinema rails or
Onto the stand or the overhead camera and let it run all day long. That's a solution that really makes sense

Atheist Problem of Evil (Greg Bahnsen) - Duration: 10:58.
The problem of evil is first of all a logical problem
Let me try to explain
you'll be told that Christians hold to a
Series of premises and that you cannot hold all of those premises
Consistently and I'm going to simplify this we believe that God is Allgood
Secondly, we believe that God is all-powerful
Thirdly, we believe that evil exists but as the argument goes if God is all good. He wouldn't want that evil
Secondly, if he's all powerful he could eliminate that evil
Therefore if evil exists God is either not all good or not all-powerful
And that's the logical problem of evil allegedly
There's an incoherence in the Christian worldview because we have premises which will not logically hang together
But I'm going to ask this question
If you if you remember I put up on the board again the four things you keep looking at
When somebody gives an argument against Christianity you want to know if that argument will fly ask is this an arbitrary?
Consideration are there inconsistencies in this presentation? What are the consequences of it? What are the preconditions of it?
For whom is evil logically a problem
is
Evil, logically a problem for the Christian or is evil logically a problem for the non-christian
It should be obvious upon reflection that the unbeliever
cannot urge the problem of evil against you or against me unless
The unbeliever has the right to assert there is evil
If there's nothing that counts as evil
then there's no problem of evil that has to be accounted for and so it's crucial to the unbelievers case against
Christianity to be able to assert that there's evil in the world
To evaluate some specific instance as an instance of evil
So, what does the unbeliever mean by good and evil by what standard does the unbeliever determine
What counts as good or what counts is evil?
What are the presuppositions in terms of which the unbeliever makes any?
moral judgment about goodness or evil
whatsoever
Perhaps the unbeliever takes the word good and evil to pertain to what evokes public approval or disapproval
but if evil or good pertains to the evoking of approval or disapproval that on the basis
On that basis. The following statement would always be
Senseless, we sometimes say the vast majority of the community
Heartily approved of and willingly joined in that evil deed
but you see if evil is what evokes the community's
Disapproval then it could never be true that the majority of people engaged in an evil deed
The unbeliever you see is using a concept of evil that
Actually precludes a very common line of discussion or comment in the English language
The fact that a large number of people feel a certain way doesn't
Shouldn't rationally convince anybody that that feeling is correct. Ethics doesn't reduce the statistics
Ordinarily people think of the goodness of something as evoking
Their approval rather than their approval
Constituting it's goodness
See even unbelievers talk and act as though there are personal traits
Actions or things which possess the property of goodness or the property of evil
Irrespective of the attitudes or beliefs or feelings that people have about those traits actions or things
Now if there's problems in saying that good and evil are defined but what evokes the approval of most people or the
disapproval of most people then the problem is even worse if you think that good is defined but what evokes the approval of the individual
rather than the public at large
By the use of the word good somebody means I approve
Then it turns out that we could never ever agree with each other in ethical judgments
If good means Greg approves of it
So when I say, you know helping that old lady that was good and sometimes is okay
Good means evokes the approval of the speaker
Then it turns out you and I can never agree on an ethical judgment, you know, why
because when I say helping the old lady is good what I mean is I approve of it when I say that you
Think helping the old lady is good. That means that you approve of it
But that you approve every button that I approve of it is not the same
judgment one is a judgment about me one's a judgment about you and
Therefore there is no public or objective nature to good
The unbeliever usually turns then to what's called
instrumental theories of good saying that good is defined by the consequences that are brought about by an attitude or an action an
Action is good. If it achieves a certain end like the greatest happiness for the greatest number what we call utilitarianism
now the irrelevance of that concept of goodness for making ethical determinations is
That one would need to be able to rate and compare
happiness in
Order to make any judgment about goodness
If I say the good Act is what promotes the greatest happiness for the greatest number then I need to be able to evaluate
Or in some way measure the happiness that is created by the action
Moreover I need to be able to compare because some actions might bring
unhappiness to a few individuals or maybe to emit too many and the same action would bring happiness to a
lot of individuals or a few so you have unhappiness and happiness that have to be balanced and
Then you have to draw on that judgment
Okay, so I'm gonna give you an illustration
Let's say we take one of the students at the conference maybe one of the students that's you know, particularly disliked
Hasn't been showering using deodorant this week
And I bring this person up here and I say now I've got this pin and I propose to stick this pin in this individual
Now how many of you are going to be made happy by my doing that?
Why don't have it? I said how many of you think it's gonna hurt him? That's why we want you to let him have it
But you see I've got to measure his unhappiness if I'm going to be a utilitarian
Okay, and so what if the person now appeals with nice ways like your buys that don't take the bid in me I say give
me an argument you
Utilitarian you he says well it so happens that the amassed
unhappiness that I will undergo
Outweighs the total happiness of this group. I
Said well, I don't think that's true. But he's going to say well then how do you prove otherwise?
You say utilitarianism which appeals to so many people in fact liberal theology thinks utilitarianism
Which was destroyed philosophically long before Joseph Fletcher got hold of it and thought that was the way to define love
Utilitarianism makes it impossible to make moral judgments
All we can do is guess at what would bring the greatest happiness for the greatest number
We can't really prove it one way or another because we can't calculate all the consequences and we can't compare pains and pleasures
Utilitarianism is really unworkable. But there's even a more fundamental logical problem with utilitarianism
Utilitarianism or any consequential
instrumental view of goodness says
Good is what produces a particular end?
But you see you could only know that that was good if the end that is mentioned is what?
Good
that is to say
Consequential theories of ethics always begged the question as to what is intrinsically good
As I say well the good is whatever achieves this goal
Libertarians will say it's good if it maximizes freedom for people
Well, they're right if freedom for people is itself good, but that's what has to be defended
Unbelievers, don't do that
So I've tried to run through quickly some views of goodness that have been propagated in the 20th century
evokes approval public
Individual or as instrumental and it turns out none of them are workable theories of meta ethics
That is the philosophy of ethics. What is the nature of good and evil? Why am I bothering to bore you with these illustrations because
If the unbeliever says you have an inconsistency in your system
You say God is Allgood you say God is all-powerful
And then there's this evil you have the right to say
Can you prove that that's evil and it turns out they can't prove that what they're talking about is evil
The point is you can say that it's evil because your worldview accounts for that judgment
Because there is a living and true creator of heaven and earth who sovereignly controls all things and his character is holy and
Unchanging has revealed himself and so forth and so on. It makes perfectly good sense for a Christian say child molestation is wicked
It's abominable in the eyes of God. I would argue that it should be punished with death. It's so terrible
But I can make sense of that. What you want to know is how can the unbeliever make sense of that?
When a person condemns child molestation or you can pick whatever example you want they are assuming moral
absolutes
but moral absolutes cannot be made sense of are not
Intelligible, except in the Christian worldview. The problem of evil is not even
Intelligible, you can't even make sense of the problem of evil unless you begin with the Christian conception of the world

AMAZING PLANTED AQUARIUMS - Aquarium Design Group. Aquascaping Masters - Duration: 15:24.
you
if there was going to be a dream team of
aquascape birds coming out of the United
States we've got some guys from the Aqua
campers collective that would be on that
team but if I had that grab two captains
for that team you're staying at them
right here we've got Jeff and Mike Cenci
from the aquarium design group I'm sure
many of you have heard of it if you have
it in about 2008 I went to the aquatic
Gardeners convention and I saw these
guys aquariums and it kind of changed my
game and they both have studied under
the late takashi amano and have been
instrumental in the aquarium just design
game here in the US you can see some of
the stuff coming on behind here I am
super excited to have it they have an
amazing gallery down in Houston then
I've had people that have nothing to do
with playing aquariums or design stay
it's simply remarkable
just like pioneers these guys do
background designs for some of the like
ready-made designs it's a great honor to
introduce Mike and Jeff's desk in the
aquarium design group thank you so much
thank you desk
I'm babysitting introduction there
that's how it is really awesome thank
you so much
so yeah it's real honor to be here this
shows been absolutely just exceeding all
expectations so yeah I guess we're just
gonna maybe talk a little bit about our
philosophy kind of what our perspective
is on aquarium hobby and maybe a little
bit about the industry in general our
approach and a lot of what we do with
the designs we create and a lot of the
sort of aquascaping philosophy that we
employ is geared towards attracting or
or showing somebody something I think
most of us would agree is a is a fairly
sophisticated expression inside the
aquarium right this is a this is not
blue gravel and a bubbling sea chest not
that there's anything wrong with that
but it's showing something that's
sophisticated or has an eye for
aesthetics or design or composition or
kind of leading with design I'd love to
see just a cultural shift where it was
just more common for people to have
aquariums in their spaces and we're
always looking to ways
to do that you know and just on the
subject of resources with the fantastic
you know Aquos capers collector here and
you guys as you know hip with the fourth
place award in the ia plc this year
number one of just a massive
accomplishment for any an Aquos caper to
an even more significant accomplishment
for a for somebody who aquascape twith
in the u.s. there's a couple of other
guys that put us a but they you know if
you're putting USA as your entry is fine
but you live in Japan and this is a
different thing and by that I mean the
resources available this ties into kinda
what I'm talking about as far as our
philosophy but to achieve a high level
work in the United States today we talk
about the world stage of aquascaping
this is a much much much bigger feat
that the rest of the world I don't think
has any idea because the guys
aquascaping in that Asian and European
markets unless you've been there you
cannot begin to fathom the depth and
vastness of the resources there so to
pull together something what if did
takes a lair of a vision and
determination and creativity that I I'm
gonna make it my a little personal
campaign maybe here in the social media
everything else over the next year to
really kind of draw a little attention
to the significance of that given the
bordering on scarcity of the types of
resources specifically for aquascaping
that they have in the rest of the world
that I think we're all really really
passionate about building here obviously
guys like Dustin to just just really
doing the work to try and bring these
things to everybody and even at that I'm
sure knowing that the struggles and
obviously increased demand just fuels
all of this and so while sometimes in
our work you might see a plastic plant
you may see you know a lot of our
hardscape only designs are very minimal
you know that I know isn't necessarily
to the tastes of everybody's particular
niche perhaps but just always know that
that's what what I when I put a plastic
plant in the tank it's really only
trying to open the door it's trying to
show greater opportunity to people as an
entry point because as all our
high-level Aquos papers here know do
that is not an easy thing to do and
there's a body of mod knowledge a lot of
experience if you just set up a plan of
tank with co2 bright light and soil
don't don't have travel plans for at
least the next 30 to 60 days I mean it's
just it would be a mistake you're not
going on vacation for a week because
you're gonna be needing to keep an eye
on this thing you're going to be doing
the water changes all the rest of it
this is my brother Mike first of all
thank you Destin I always enjoy talking
on the phone thanks for having us over
here and sharing the love brother and
staying diligent and doing the work and
boots on the ground and making it happen
and awesome to see the like debacle
escapers here as well keeping the
movement going aquascaping the live
aquascaping demos over there and working
with people i think is amazing gives
people a first animist initial
experience of putting it together and
how cool it can be meant all that for
both speaking for Jeff also it's been a
it's the whole Aqua Shella thing we
haven't done any things like this we
haven't he just been to the aquatic
experience and stuff but I haven't been
out to things that these things in a
while so it's always nice and refreshing
to get away from a DG and just the
inspiration and meeting and seeing you
guys and just getting all the positive
feedback and all the love and everything
and taking all that that back with us as
well but I think what Jeff said you know
he's better wording it properly to just
overall philosophy and
with aquascaping in the design and just
the initial inspiration and getting
getting those people you know there's
all the hobbyists that are into relevant
you know do it but getting those those
people into at the aquarium lover that
that love and acorrea been approaching
it where it's just not so intimidating
you know with the right plants maybe
just kind of developed a style in the
gallery just using you know you know
anubius mosses the cardia you know
lucifer Landrieu's and things like that
that are just we're not committed to a
soil you're not necessarily committed to
daily water changes but yet it's
extremely beautiful and I think getting
people into that success early on is
important and we kind of continuing on
as well and then a bracing aquascaping
everything like you know I hate to use
like a term but like they're like oh
geez right like a good gangster so I
want to kind of take that term and
somehow tie it to a motto but I think
that I think there's they wanted to talk
about it and I think it's worth kind of
pointing out King Mike can you kind of
talk about your origins with this like
did you guys have been doing this for a
while can you kind of talk about how you
all got into it I did a kid doctor
skating contest because I want to poison
the young kids but can you talk about
like you know when you were younger how
that started and how you guys got to
become a tease you can give you a quick
cliff notes of it so aquariums go back
in our family cut but go back in our
family a couple of generations our
father was born in Germany our
grandfather kept aquariums in Germany
and had me at a young age and their
aquariums are always in the house
he's a veterinarian and even when he was
in veterinary school he had a small
aquarium store in Oklahoma so the first
time I had my five gallon aquarium and
Guppies with some floating hornwort and
the Guppies had babies that was it was
that was on from there Jeff would kind
of follow into the Hobby a little bit
later and embrace it early on in the 90s
we did have kind of I myself when both
of us have kind of work full circle in
industry as young young guys worked from
our experience in retail shops in the
early 90s we had a small retail aquarium
store took on a lot of learning lessons
at that time went on to start aquarium
design group in 99 2000 which was a
challenging year but had the opportunity
to meet a mano at this first trip here
for the aga convention at that time Jeff
who's handles all the corn design group
the social media all the photography all
the video they're all familiar with his
self talk so he has no formal training
in photography or video so we hired you
know you see our contextual
photographers shoot a picture of an
aquarium in a room you'd see the room
not the aquarium and Jeff really found a
way to bring the eternium into the space
so we travel to the first AGA and I
remember sitting in the lobby both Jeff
and I we hand Amano our pictures that
Jeff had taken of our early on
aquascapes this is 2000 2000 2001 and
that these words is still stick with us
today I'm honest said you you have
beautiful aquariums you take nice
pictures but your aquariums lack
philosophy and we kind of knew what that
has like obi-wan cannot be kind of
telling like look
no you're just putting some stuff
together there's not a philosophy or a
vision behind that so and we had the
opportunity to also become an ad a
distributor for many years that allowed
us the opportunity to go to Japan for
nature cornering parties Jeff actually
stayed there longer on one visit and did
the whole nature aquarium certification
program as well and had a two to two or
three two or three opportunities I guess
that every time I wanted would come here
for the AJ we would have him back in our
hotel room with a half gallon of Jack
Daniel's and you know through a
translator but we're able to ask a lot
of questions on it also as a business as
well you know like hey did you know did
you have that account or somebody
sitting over you when you want to go to
this Knox escape you're in the business
you know what it's like when you want to
expand or do something that inspires
people you got to think about the
dollars you put behind it and it
resonated with us as well as like now I
just I did it for the passion I did I
did it and to inspire and then the rest
would follow to follow behind that you
know so we're going on our 18th year in
business it's not said it's a chance of
challenging business a lot a lot of what
you see that we do covers everything
from you know decorative fresh water
with plastic plants to live Reed's got a
great staff or a staff of about 20 in
Houston staff marine biologists as well
we don't do a lot of live planted tanks
we actually don't do any live planet
tanks for our service and maintenance
clientele because that commitment when
they see a you know a high tech high
level they see in a mono picture in the
mirror your own personal work that
you've done you win an award with we all
know what that commitment is and so they
in the quarry maintenance service
business that's not a scalable model
would we love to do that what I love to
have a to meet you guys in Houston doing
nothing but aquascaping high level plant
tanks sure that that's in that we're not
there yet you know but that is still
Jeff and
our true core passion is definitely if
to see if he ever had to we weren't in
the business he had to take it take away
at all and say okay you guys get to
choose one style of aquarium to do and
that's it it would be the plan in the
corner for sure you have Jeff you want
to add anything to that I'm just on the
note of mr. Mona because it's I can't
stress enough and I maybe got caught up
in a little bit of a spiel yesterday
with the Aqua skaters collective guys
just about the importance and the
influence and kind of just a certain
reverence for for him that is it's just
personally I guess sort of important to
me because when we say aquascaping that
he we can trace that still to one man
and the man just passed three years ago
this isn't like a hundred and fifty
years ago there was this guy doing this
thing and it's not even like it was a
movement or there was you know a group
of 10 or 20 or it we literally can trace
the vastness of this influence to one
human being who was only just so
recently with us you know so anytime we
see a rocks and a planted tank does not
sticking up like this but tipping over
just a little like this in creating a
certain indescribable tension or a
certain feeling that if I move the rock
up two more degrees would change like
that perspective that approach that
thing that's giving us access to a
greater sense of design or composition
or almost sort of a sort of a cosmic
formula of sorts playing out inside the
aquarium you know we really can't erase
that too one man and so getting to know
him personally so early in our careers
was just me I can't I could not stay
strongly enough how influential that was
to the point that literally everything
that we've done since is informed by our
inspiration from him and I Satan know
Amano
no no Amano no aquascaping really we
would still just be kind of keeping fish
tanks all of which is fine and beautiful
but I think most of us would agree that
when we say aquascaping this thing has
been something new in the in the hobby
in the industry this this has created a
whole new dimension and brought new
people in a new resources and expanded
what the accordant is and you know any
time we're doing this sort of derivative
work you know that's really and because
if you got it from somebody else they
probably got it from him you know and so
we can really trace that back so I like
to be very careful not to take I don't
wanna I don't claim too much of this
work as I have some unique special
vision that someone else doesn't because
the very vast majority of kind of the
essence of what we do if not the actual
lay out that the essence or the
inspiration of the philosophy of that
lay out is rooted in the teachings of
mr. Amano and that's just a really big
big thing to me to always make sure that
we kind of keep that fresh on our minds
at least through this generation so yeah
absolutely big deal just really
appreciate it thanks so much for
listening

How To Find Your Profit Using The Amazon FBA Calculator - Duration: 2:59.
In this video, I am going to show you how to find your profit per unit, using the Amazon
FBA calculator
Stay tuned…
Step#1
Either find your product listing or find a product very similar to yours that you're
interested in sourcing.
Once you get to the listing, get their ASIN
Step#2
Go to google and type in "Amazon FBA calculator"
Get the ASIN from the previous step, and paste it into the calculator
The 3 points of information you will need are:
The price you want to sell your product
The cost of shipping per unit to ship into FBA
The cost of your product
Step#3
Let's break down the 3 points you need to know
You should already know the price you want to sell at
The way you calculate shipping cost per unit is divide the total cost of your shipping
by the number of units
For example, if you pay your freight forwarder $1200 to ship 1000 units
You will divide 1200/1000 and you will get $1.20/unit
You will put this into the calculator under the "ship to amazon" section
The last section is to find the cost of your product per unit
You will find this similar to how you found the shipping cost per unit
For example, if you pay $2500 for a total of 1000 units if derma rollers
You will divide 2500/1000 and it will be $2.5/unit
Now you have the 3 points of information you need to input into the FBA calculator
Step#4
Let's go back into the Amazon FBA calculator
Input the 3 points and the Amazon FBA calculator will spit out your Amazon Fulfilment Fees,
Amazon Referral Fee, Net Profit and Net Margin.
With this information, you can determine if your product will be profitable or not
I hope you guys liked this video and it was useful for you…
This is Oscar and I will see you in the next one!

How Not to Set Your Pizza on Fire: Crash Course Engineering #15 - Duration: 10:39.
Temperature matters.
In almost everything we do, we're trying to heat something up, cool something down, or just trying to maintain a temperature.
As an engineer, you'll often need to find that Goldilocks temperature, the one that's "just right" for your devices and designs.
But once you figure that out, how do you achieve it?
Well, you'll need some equipment, and to learn how to use it.
More specifically, you'll need to know about heat exchangers, and how they can affect heat transfer.
Just make sure to watch out for those three bears.
[Theme Music]
So far in this course, we've learned a good deal about heat transfer and the different ways heat moves throughout our world.
We've also talked a bit about the devices that help move heat energy, like refrigerators and heat pumps,
and how you can slow down the transfer of heat with layers of insulation.
But that's just the beginning of the ways you can affect heat transfer!
There are lots of different types of equipment you can use to transfer heat between two things.
They're called heat exchangers, because they exchange heat.
But don't let the simplicity of the name fool you.
Heat exchangers are everywhere.
They show up as radiators in cars, where they transfer heat energy away from the engine so it doesn't...overheat.
You'll also find them in military equipment and power supplies.
You can even find them in medical devices.
Have you ever had an X-ray?
Well, X-rays actually produce a large amount of heat, so they need heat exchangers to draw that heat away and keep it from damaging the equipment.
Even when you create something amazing – something that can literally see the bones under your skin – you still have to account for its byproducts.
Engineers can't just make a good meal; we have to clean up the kitchen, too.
So heat exchangers are pretty important.
Without them, there's all kinds of stuff we wouldn't be able to do.
And the type of heat exchanger you use is even more important,
because it's not always as simple as heating something up or cooling it down in any way that you can.
There's a lot more to consider.
For example, let's say you want to heat up your leftovers from last night.
Technically, you could do that by setting your pizza on fire, but unless you'd like your crust extra crispy, that seems a bit extreme.
A much better choice would be a microwave.
Maybe an oven.
Or, say your tea is a little too hot to drink and you want to cool it down.
You could blast it with a firehose of cold water, but that would likely ruin your tea, and everything else around it.
It would probably be better to just wait a bit – maybe put your tea in a colder room or leave it in the refrigerator.
In engineering, you need tools and methods that are more precise.
Surgeons have their scalpels; we have heat exchangers.
So let's look at the ones we've got!
The first, and most basic example of a heat exchanger is a concentric tube.
Here, one pipe or tube is placed inside another one, with a colder fluid moving through the center tube, and a warmer fluid moving through the outer tube.
This fluid might be a liquid, or it could be a gas.
A common place you'd find concentric tube heat exchangers is inside air conditioners.
With concentric tubes, and in most heat exchangers you'll encounter, it's important to note that the two fluids are sealed off from each other and never mix.
But as the fluids move down their separate tubes, energy transfers from the hotter outer fluid to the colder inner fluid through the wall of the inner tube.
That's the heat transfer.
In some concentric tubes, the fluids will flow in the same direction – what's known as parallel flow –
and other times they'll move in opposite directions, which is called counterflow.
Whichever way the fluid flows, You'll probably want to know just how good the heat transfer is.
That's the point of a heat exchanger after all.
There are two main equations for heat transfer that you can use to figure this out.
The first looks at each fluid individually, and defines heat transfer – represented with the letter Q – as the product of three of the chosen fluid's properties:
its mass flow rate, m, or how fast it's moving;
its heat capacity, c, or how much heat you need to raise the fluid's temperature;
and its change in temperature, ΔT, after it passes through the heat exchanger.
This equation tells you that no matter what, if there's a greater change in the fluid's temperature, there was more heat transfer.
Which, obviously.
It also tells you that there's more heat transfer if it's a type of fluid that just generally needs more heat to raise its temperature.
Finally, it says that it takes more heat transfer to accomplish a given temperature change in a fluid that's moving really fast.
If each particle of fluid isn't staying in the heat exchanger for very long, you need more heat transfer to raise its temperature quickly, before it leaves.
Let's say you have a heat exchanger with the colder fluid in the inner tube moving at a high flow rate and the warmer fluid in the outer tube moving slowly.
Even if there's plenty of heat being transferred, you might not get a major temperature increase in the inner tube since it has such a high flow rate.
Meanwhile, all that heat being transferred to the outer tube will cause a significant temperature change, since it's moving so slowly.
Which is what we want!
The whole point of a heat exchanger is to accomplish that significant temperature change.
Now, the other equation for heat transfer also describes it in terms of three properties, but it takes both fluids into account:
The first property is the heat transfer coefficient, U, which is a measure of how easily heat is transferred between the fluids through whatever is separating them;
second, there's the area, A, over which the heat transfers;
and third, there's the temperature difference, ΔT, but this time between the two fluids.
The heat transfer coefficient is actually the inverse of the thermal resistance we discussed last time,
so the larger the value for U, the less resistance there is, allowing for more heat transfer.
This equation also tells you there's more heat transferred when there's a greater area of contact between the two fluids.
And no matter what the heat transfer coefficient is or how much contact there is between the two fluids,
a greater temperature change will always involve more heat.
You can use these two different ways of defining heat transfer to change your operating conditions as necessary and get the heat transfer you need.
In the design of the heat exchanger, you can affect the heat transfer through the heat transfer coefficient and the area of contact between the fluids.
And while the heat exchanger is up and running, you can affect its heat transfer by the temperature differences between the fluids and their mass flow rates.
But all of this leads to some inherent problems with the simple concentric tube heat exchanger.
If the temperature difference between the fluids is the driving force,
then the heat exchanger will need to have an appropriate area and U value to achieve a reasonable amount of heat transfer.
There are two ways to increase that heat transfer: increase the value of U, or increase the value of the area.
You could increase the heat transfer coefficient by using more conductive pipes or making them thinner, but at a certain point you'll hit a physical limit.
Which leaves you with only one real way to increase the heat transfer: increase the area of contact between the fluids.
For a concentric tube design, the only way to increase the area is either by the pipe's radius or length, which isn't too practical.
For one thing, the heat exchanger will take up more space.
And it's going to increase not only the cost of the building materials, but the operating cost of any pumps pushing the fluid through the device as well.
If we only used concentric tubes in our designs, we'd need more space under the hoods of our cars and our X-ray machines would be even bigger and clunkier.
So it's worth looking at some other heat exchanger designs too.
Take finned tubes, for example, which you'll often find in industrial applications like power plants, industrial dryers, and in the air conditioning units of large buildings.
In these designs, fins are added to a tube to increase its surface area, which enhances its rate of heat transfer at the same time.
There are two main types of finned tube designs.
With axial fin structures, fins run along the tube lengthwise.
They're best suited for devices where fluid flow outside of the tube is slower and more viscous, like oil, but you still want it to distribute a greater amount of energy.
With radial fin structures, on the other hand, discs are added to the tube and spaced out from each other, usually in regular intervals.
This type of finned design is best suited for a faster-moving fluid like air to flow around the tube.
Another heat exchanger worth looking at is the plate heat exchanger, which uses metal plates to transfer heat between fluids.
With these, the warmer fluid flows through one port and the colder fluid flows through another, typically in counterflow.
Both fluids are restricted by seals so they can only follow a certain path, kind of snaking their way through the exchanger.
The fluid between each set of plates alternates, with the plates providing a large surface area for a high rate of heat transfer.
So, plate heat exchangers would be a little better than concentric tubes for something like an X-ray machine, since it produces a lot of heat you'd want to get rid of.
Now, both finned tubes and plate heat exchangers are usually a step up from concentric tubes,
but one of the most common heat exchangers is the shell-and-tube design.
You can find them practically anywhere, from large oil refineries, to engines and transmissions, and even in swimming pools.
Like its name implies, a shell-and-tube heat exchanger is made up of a larger shell with a bundle of smaller tubes inside it.
One fluid, usually the colder one, moves through this series of tubes while another fluid flows outside of them and through the shell.
There would be large pockets of stagnant shell-side fluid in the corners of the shell if this design was left as-is, though.
So you can put baffles, which are obstructing vanes or panels, inside the shell to drive the shell-side fluid through in a maze-like pattern.
Baffles not only help to increase the overall average heat transfer through the system by directing the flow of the fluid,
but also by increasing the shell-side velocity and promoting turbulence.
So, between concentric tubes, finned tubes, plates, and shell-and-tube designs, you've got plenty of options when you need to transfer heat.
Which, among other things, means there's no need to set any pizza on fire.
That would just be a travesty.
Today we learned all about the different types of heat exchangers and how they can be used to transfer heat.
We started off with concentric tubes , and the two main equations that can help us define heat transfer in heat exchangers.
Then we flowed on over to finned tubes and found the differences between axial or radial fins.
Finally, we covered plate heat exchangers and studied the most common heat exchanger design: shell-and-tube.
I'll see you next time, when we'll continue on our journey and learn all about mass transfer.

What if Carbon Emissions Stopped Tomorrow? - Duration: 5:57.
Imagine that aliens landed and gifted us a clean, limitless energy source.
And instead of killing each other over this technology, we decided to immediately transform
the world into a carbon-free society.
[animation shows closing drilling rigs, oil refineries, and coal and natural gas plants.]
This wonderous source would power our homes, industries, cars and planes, and humanity's
annual rate of carbon pollution would almost instantly fall to zero.
So if we kicked our carbon addiction tomorrow, what would that mean for global warming?
[Intro]
Hey, I'm Joe.
So, if we stopped burning carbon tomorrow, would the climate suddenly go back to the
cooler, calmer atmosphere humans lived under before the Industrial Revolution?
Short answer: Not exactly.
The climate would continue to change and temperatures would remain high for many, many centuries.
So, that's not great.
I know, we've been told for years that slashing greenhouse gas pollution is the key to tackling
climate change.
But unfortunately those cuts wouldn't immediately stop the planet from warming up.
One reason is that over the last 50 years, 90% of the
extra warming has gone into the oceans.
[average depth on screen: 2.3 miles, note that "oceans mix slowly"] It takes decades
for oceans to heat up, but once you quit adding additional heat they'd still give off the
heat that had previously accumulated.
It's kind of like how a pot of boiling water continues to give off heat long after you've
turned off the stove.
Because water heats up slowly, it cools off slowly too.
And as all this extra heat fully mixes in the deep ocean [show heat equilibrating in
the graphic] the oceans would continue to expand, raising sea levels for centuries.
The other reason Earth would stay hot is that CO2 molecules -- which cause more than 80%
of the warming -- remain in the atmosphere for a remarkably long time.
If you burn 5 gallons of gas [show car driving] today you create about 100 pounds of CO2 [illustrated
in animation].
But way off in the year 3000, as much as 40 pounds of that gas will still be floating
in the sky, warming up the planet.
Earth has warmed by about 0.8˚C [1.4˚ Fahrenheit] since the industrial revolution.
If we turned off greenhouse gas emissions tomorrow, shorter-lived greenhouse gases like
methane and nitrous oxide would be chemically broken down and dissipate first.
That would cause the atmosphere to cool by maybe half a degree, over about a century.
But CO2 stays in the atmosphere way longer, because it's so chemically stable.
So that would keep , the earth warmer
for at least two thousand years.
So, many of the impacts we're experiencing now, like the melting arctic, drier droughts,
and fiercer thunderstorms would probably also continue.
In the end, CO2 might take as long as 100,000 years to finally return to pre-industrial
levels.
So even if we cut all emissions tomorrow, the truth is we are guaranteed some amount
of climate change and warmer temperatures.
But switching to a carbon-free energy system
would still give us a lot of benefits immediately.
Health is a big one.
Over three billion people worldwide breathe air that is so polluted that it doesn't
meet World Health Organization guidelines.
Air pollution from fossil fuels or stoves is thought to cause more than 5 million deaths
per year, thanks to things like lung cancer, heart disease, and stroke.
The majority of those deaths occur in developing countries, where there's more pollution.
So halting fossil fuel burning would immediately improve the lives of millions of people.
Wild places would also benefit.
Some of the world's most pristine environments contain plentiful fossil fuels.
Stopping emissions would mean ending fossil fuel extraction, which means less construction
in wild areas, less noise pollution, and cleaner air and water.
Halting emissions sooner rather than later means that future generations might still
face climate impacts, but they'll probably be less severe.
For example, with each degree of additional warming, the amount of area burned by wildfire
in the western United States doubles.
Each degree of additional warming is also thought to reduce crop yields by as much as
10 percent.
Lowering emissions means fewer fatalities in extreme weather, fewer severe storms, and
more children spared the hardship of migration to cooler places.
And who knows, maybe one of those kids could grow up to develop some technologies to actually
suck the extra carbon straight out of the sky and speed up the cooling.
The idea of aliens providing us a magical energy source is of course a fantasy.
But today we're already installing real clean energy technologies that could wean
us off fossil fuels, things like solar cells and wind turbines.
The decisions we're making today will affect not only our grandchildren but their grandchildren's
grandchildren.
's grandchildren.
's grandchildren.
's grandchildren.
Our addiction to carbon has put us and our descendants into a deep hole.
Sometimes it's hard to imagine how we'll climb out, but the best thing we can do for
ourselves, and for them, is to just stop digging.

Why People Are Sending Themselves Hate Messages - Duration: 5:29.
[♪ INTRO ]
You're probably familiar with the concept of self-harm.
When you see it in books, movies, and TV shows, it's usually portrayed as some troubled
person seeking a physical outlet for their emotional pain.
But that's only part of the story.
Self-harm, or what psychologists call non-suicidal self-injury, isn't just physical.
People can hurt themselves in all kinds of ways — including, as it turns out, through the anonymity of the internet.
Finding coping strategies is crucial for taking care of your mental health.
But first, you have to be able to recognize when there's something wrong.
And because digital self-harm is still a pretty new concept, people who hurt themselves this
way might not even realize that what they're doing really is self-harm.
There are lots of reasons people might feel an urge to hurt themselves.
Usually, it's because they're trying to release extreme negative feelings that come
from other mental health issues, like depression or low self-esteem.
Often, people who self-harm say they want to punish themselves, or relieve unbearable mental tension.
And for some, it does lead to a few moments of relief.
So they keep doing it.
But hurting yourself does nothing to address the underlying problems or feelings of hurt, which can get worse and worse over time.
It's just … causing harm.
The classic picture of self-harm involves physical injuries, like cuts and bruises,
but it can be much more subtle than that — to the point that people don't even realize they're doing it.
For example, overeating, or even over-exercising, can be a form of self-harm.
And now that we're in the digital age, psychologists have begun to see a new type of self-harm emerge — one that isn't physical.
Digital self-harm is when you hurt yourself emotionally, using the anonymity of the internet
to make it seem like you're being attacked.
Think anonymous hate messages on platforms like Twitter or Tumblr, but instead of getting
them from some random troll, you send them to yourself.
That doesn't mean every hate message you've seen online is a case of digital self-harm
— unfortunately, cyberbullying is a very real issue.
Just spend any amount of time in the comments section of a trending youtube video … you know? Actually, just don't.
But sometimes people do send hate messages to themselves.
It's surprisingly common.
One 2017 study from the University of Wisconsin-Eau Claire,
which involved nearly 6,000 American middle and high school students, found that 6% had anonymously attacked themselves with mean comments online.
There was a slight difference between sexs, with about 7.1% of males and 5.3% of females saying they'd done it.
And an earlier study from 2012 on about 600 students found that around 10% had some experience with digital self-harm.
About half of those 10% said they did it very rarely, while the other half said they did it pretty often.
A quarter of them had sent themselves hate online for months at a time.
If you don't have much experience with digital self-harm, this might be kind of hard to understand.
I mean, the person doing it knows they're the one who sent the message, so what's the point?
Well, as you can probably imagine, there's no one simple explanation that fits everyone who sends themselves anonymous online hate.
But like with physical self-harm, it's generally a way to express their negative feelings about themselves.
And researchers have found some more specific themes, too.
Also like physical self-harm, digital self-harm is associated with depressive symptoms, as
well as marginalizing factors like sexuality, drug use, and being bullied.
Then there's the social media problem.
We'd need a whole separate episode to get into the details, but researchers are finding
all kinds of connections between social media and mental health issues.
Among other things, as more and more of our socializing is done online, it's gotten easier to become isolated.
As much as social media is meant to connect us, it can leave us feeling pretty alone, too.
And when people feel disconnected from others, they're more likely to develop negative
feelings about themselves, or have depression or anxiety.
In a 2017 paper from the University of Manchester, researchers examined data from 2014 and found
a massive increase in the number of teenage girls who reported self-harming.
77 out of every 10,000 girls practice self-harmed that year, as opposed to 46 out of 10,000 in the years leading up to 2014.
That's an increase of 68%.
The team suggested that part of the change might just come from increased awareness of self-harm
— and therefore increased reporting of it.
But they argued that psychological pressure from social media was probably an important factor, too.
This study didn't break things down into physical and digital self-harm, but it's
but it's not too hard to imagine that added pressure from social media could lead to more self-harm via social media.
So, this all tells us a little bit about how people use digital self-harm as a coping mechanism.
But what about the people who do it specifically because they want people to notice?
Thinking about self-harm this way can be dangerous, because it's sometimes used to dismiss a sign that someone really needs help.
But some researchers think there are cases where digital self-harm is, at least in part,
a way for someone to get concern, attention, and admiration for their ability to cope.
It might even be a digital version of what's commonly known as Munchausen's syndrome,
although its clinical name these days is factitious disorder.
That's where someone fakes an illness to get care and attention from others.
But when they get that concern, or admiration from others for their strength, it can actually
mitigate some of their negative emotions and make them feel better.
So regardless of the motivation, it really comes down to the same thing
— using self-harm as a way to deal with overwhelming feelings.
We still need more studies to figure out how best to identify, reach, and treat people who use digital self-harm.
But in the meantime, increasing awareness of it helps, too.
In the end, it doesn't really matter what form it takes — self-harm is self-harm.
At best, it's an unhealthy coping mechanism, and at worst, it can be dangerous.
But by recognizing the problem and getting help, you can learn better ways to deal with your feelings,
and resolve the underlying issues that make you want to send yourself anonymous hate.
