I am getting bullied... On the internet... - Duration: 6:25.
*Phone rings*
I wonder who is calling me?
Where is my phone?
Oh it is right here.
Rasat I gotta tell you something
Yo, What happened?
You got roasted!
*Sad soundtrack*
*Intro Music*
Hey what's up
everybody
I don't know why I did that just to, just to
look cool alright and that today I'm
going to be reacting to this guy roasting me
so yeah this kid roasted me,
I got roasted by a kid
how embarrassing is this but you know when you
get roasted that means your relevant
haha I am some what relevant
yeah so I got roasted, if you guys
want me to send a diss track back at him
smack that 10 likes and make fake
accounts because only got one person
watching me and you know you are, no one is watching me
editor play that video
Sup guys
ugh the black bars, come man learn to record landscape
all you gotta do is
turn you phone right, turn it landscape
landscape right it's just like I do it
like that don't do it like that for
selfies right that's what selfies before
this like record like that it's like a
cum rough because Lance like my videos
we are you know that i'm just showing up
now that i can record like eight hours
did alright you know that matter you
know with blackboard just gets annoying
please don't do that like it's like you
can only see off with me i don't know
and no you don't rush me for what I'm
wearing and some people and Rosie so
this is don't make me jump express time
because you just because of the black
bars
come on please please please let
temperatures idealistic what's that
intro please please for me like I'm
maybe some people are smarter than me
i'm not very smart i can understand you
when you're talking really fast alright
alright i just did and then divide this
talk really fast are contrary to that
because that's it with me so pleased
that talk slower and yeah they'll be
breaking youtube us why saw oh that's me
and of ya hope you're watching it
doesn't mean anything like we do it for
guillotine your body like right spot
oh I am working and I'm elements they
keep that simply these kids that they
can get that roast um I don't like him
better when he get yes a really like the
distract the what locals little i guess
it was pretty late in this video I mean
Christmas with last year
and a 20-17 now and then it's pretty
late i guess i just love that wide
ok speak louder than I cannae you
perfectly
wrap that disgusting go get some
laterally none of those lips that's
crusty-ass lips for thought
I'm 16 or I'm kind of proud my age and
pretty damn old you know back in my day
eve kids dinner roast me for being a kid
when your kid yourself and you know I'm
back in my days that's not how I work by
gets and change channel suggest you
about clock
yeah somebody's what this movement of
cloth yeah much almost did you know he's
taking shots are you guys now not me he
didn't want me a goshawk pretty
disgusting
ya-ya-ya-ya-ya you got skype i'll go
with three doesn't know me because you
only got 20 and I'm one of them
how do you feel class people before the
state Chris ready to battle you were
eight
let me tell you that there's a very real
way where you going to tell me something
and then you point the camera at this
kid like that
yeah I wait so we both stop copying
right so the only difference with a USB
I saw that only different
alright cool to be honest that was a
decent bar plus it was true i do some
marshmallows away and you know you had
to pick them state instead because it
matches my skin color you know Brown
yeah makes sense of their please
yeah you know just call me a potato next
time
absolutely
yes a lot
123456789 10 dyno numbers they are i've
been to school ok that people can't buy
that is no Road man I'm more like creepy
and Callisto I don't drive by your
output 5 i'll type of front thought what
we do in my uncle was a bit suspicious
when you bought your face trouble cover
off our display if you're in a race
called Lost Lake isn't that the guys
this was the distract on this was a
distracting me another person to
distract me but i'm not sure if I want
to do another reacting with the or maybe
if you guys give me enough support bleed
in the comments on Sam say amazing i'm
insecure but now i'm pleased am amazing
oh yeah so yeah definitely share this
video with your friends and how now you
don't know friends it's only me and now
that you're here it's like to meet this
year it's someone else please
I mean don't need to be used to rank i
hope you'll have an amazing day this
video then give me much time to make
music
yes yes I'm still getting the same and
revenues so yeah Peter goes our way I
forgot to give a shout-out to move so go
check out his general be linked in the

Interstellar Travel Challenges - Duration: 28:47.
one of the trickiest things about
traveling through the vast vacuum of
interstellar space is that it isn't a vacuum
So today we are going to be
taking a look at some of the
difficulties involved in interstellar
space flight and some features of
spaceships we haven't discussed before
time constraints we have looked at
spaceships many times and interstellar
colonization to but today's topics take
some time and we'll never absolutely
vital to the topic at hand here are the
key topics we will be covering today
number one how fast ships can go number
two the non vacuum of space number three
collisions and protection and number for
the shape of a ship we will also be
joining all guardianship immunity from
the life in a space colony trilogy you
don't need to have seen those episodes
to follow along with the discussion
today but it saves some time to use them
and I've grown rather partial to the
ship as well mind off that ship mast in
a couple hundred million tons was half a
kilometer wide and a few kilometres long
we have visually rendered it before but
that was always more conceptual than
accurate it had a crew of 200,000 when
it left or for the towel study system
and as it traveled a 10-percent of
Lightspeed it need 120 years to arrive
they are they had a lot of people born
during the trip and also enjoyed massive
extended lifespans something will
discuss more next week plus they were
receiving constant if delayed text
updates from Earth and you can make a
lot of technological progress in a
century all of which meant they had more
people when they arrived than originally
planned and the technology to do the job
better and with less people
many of the folks had adjusted to
thinking of the ship as home and being
raised to think of colonizing solar
systems as their life purpose and the
award view probably would have altered
to view that as one of the greatest
accomplishments of person could label
towards so was no big surprise they
decided to continue their journey on
Ward planting coneys like seeds in a
great big galactic golden on the total
Johnny toward the edge of the galaxy and
maybe beyond but the ship was not
designed for that and again they've got
a century of technological progress as
the ship was built so they decided to
retrofit unity before leaving town SETI
they pick as their next destination 82
gee you're Donnie a system around a
Yellow Sun that liked our study is a bit
order smaller and dimmer than alone son
it is more or less in the same direction
Tau Ceti years from or just a bit for
the alarm Tau Ceti is 12 light years
some more candy to ger Donnie is 20 but
it's about 12 light years from now
setting being off at a bit of an angle
so it will take them as long to get
there as therefore strip they'd like to
do it fast on and not need 120 years to
couple 12 light years the engineers say
they can boost the speed to twenty
percent of light speed and a 60 year
journey
however they are leaving with just a bit
over 50,000 people so they still need to
populate but you don't need a century to
double quadruple your population
especially when folks are not aging they
don't die off and they can keep having
kids indefinitely so they have no
problem rapidly increasing their numbers
in a few generations though generation
ceases to mean anything in this context
people still having kids while their
grandchildren all they're thinking
ideological ship to not just a faster
one so we need to retool the ship and
the captain calls a meeting of all the
senior staff ignoring for the moment
that we have been assuming this was a
democratically operated civilian vessel
who probably has an elected provisional
governor calling the shots
same cabinets before she looks mid
twenties but has been commanding ships
at the old interplanetary vessel
Hyperion so there's a couple centuries
of experience they'll enter actual ankle
rating is probably something like glad
more by now and she runs a ship that has
more people in it than most talk to your
navies have personnel how fast can we go
she asked and why can we go faster now
Oh science officer speaks up and says
that's not how this sort of thing walks
we can go as fast as we want the problem
is it takes exponentially more fuel to
go fast off every type of fuel that
classifies as a rocket has an exhaust
velocity how fast the stuff comes out
the back to get your ship up to that
speed you need for sixty-three percent
of it to be fuel that's just how it is
and if you want to be able to slow down
at the end you need to be eighty-six
percent fuel a ship that doesn't need to
slow down can get twice as fast as one
of the same fuel ratio if you're killing
us if you want to get to double your
exhaust velocity and not slow down you
need to be eighty-six percent fuel if
you want to slow down you need to be 98%
fuel leaving only two percent of your
mass for ship and cargo if you want to
get to triple that speed and slow down
you need to be 99.7 5% fuel me you've
got 400 times as much fuel as your ship
and its cargo this is why we need rocket
the size of tall buildings to get
shipped the size of cramped apartment
into space from or because the exhaust
velocity of a normal market your is
considerably less than the escape last
leave or even ignoring your drag getting
to higher and higher speeds compared
your locket exhaust velocity requires
exponentially more fuel their ship unity
use fusion which has vastly hi exhaust
velocity than chemical fuels usually
estimated at a decent if low percentage
of Lightspeed
the science officer says that what
changed is the new reactor designs from
off let them achieve a more efficient
degree of fusion and results in a higher
exhaust velocity twice what it was
before we will see it used to be five
percent of Lightspeed that the fusion
products are leftovers flew out at
before and now it's ten percent that's
on the conservative lower and higher end
of what we anticipate from a good fusion
drive it also means that whatever the
mass of the ship the cargo is when cured
up it will be about 50 times more better
than that and when it is done
accelerating after some weeks or months
to its cruising speed it will still be
about six times more fuel than ship the
captain asks why not just go with a
highly show even more fuel
after all there is no shortage of
hydrogen available nor minerals to make
the tanks out of but that's where the
weapons officer chimes in it won't walk
he says the court system was designed to
let them avoid collisions in
interstellar space at ten percent of
Lightspeed by going twice as fast they
will encounter those objects twice as
often and each killing four times the
energy and damaged capacity the Science
Officer nods and fix that up as he's a
bit of a large window fellow who usually
needs 20 to 40 minutes to get to the
point he said the interstellar medium
all the gas and dust between the stars
is quite then and most of it is hydrogen
and helium gas molecules with the super
majority of the tiny amount of mean
being very tiny motes of dust continue a
handful of atoms to those are not a
problem they act like radiation and you
just make your forward shooting a bit
thicker hours will mostly be thin metal
containers full of fuel hydrogen because
hydrogen is quite good at starting
radiation but we have to worry about is
things that will make big holes or even
trash the ship and since smaller
particles are a lot more common than
bigger ones we will run into a lot more
then as a very loose rule when it comes
to media voids and micrometeoroids
there's about an inverse relationship
between mass and frequency you expect to
encounter stuff twice as massive about
happens often
meaning that since everything is hideous
with four times the energy since we're
going twice as fast
something with a quarter of the mass
will do the same damage as we're going
half speed but those objects are now
four times as frequent to make it worse
since we need to vaporize the stuff and
are going twice as fast we will be
encountering them twice as often so
eight times the frequency of the stuff
we need to shoot down and we need to
detect them twice as fallout to have
time to react to them we need to detect
smaller things for their way even was a
little local bubble the galaxy is where
the low and density compared the
Galactic normal which is about 10 times
nickel then the interstellar medium is
locally this ship is not going to remain
in that bubble and indeed may pass into
areas where the density is follow hiyo
so best prepare now while we are making
our ship bigger faster and better nor
the medium homogeneous you might go
through short patches where the density
is hundreds of times higher
needless to say this are gets washed the
faster we get at the speed we are going
your typical grain of sand wait about a
milligram will hit us like half a ton of
dynamite around a million times the
energy of the average bullet we can
easily arm with a hole against normal
bullets but these often head size
objects that will penetrate rather
deeply leaving small large halls so even
one just killing that much energy is
something I'd rather not be hit by
even as huge a target as unity is being
half a kilometer wide and tall we still
only encounter about the equivalent of a
bucket of sand doing a century-long trip
in terms of cosmic dust and most of that
will still be too small to hold us even
at these speeds but it is still enough
that you might expect to run into a
grain of sand as often as once an hour
and something the size of a pea which
will hit us like a small nuke maybe once
a month but something killing bullet
force that we would run into almost
every second it will be only a handful
of micrometers across the width of the
thinnest hails we need to see that tiny
mode phone off out to target with a
laser and vaporize it and we are
traveling 60,000 kilometers per second
fast enough to travel from Earth to the
Moon in six seconds fast enough to get
to the Sun in 40 minutes even computers
need time to get mac your track on an
object name which usually involves
moving something then shoot and hit
something smaller than a grain of sand
though we'd probably use a wide beam and
go for overkill to compensate for
positional uncertainties needless to say
it takes a very powerful radar system
together towards us something that small
following up a way to help us and it
can't be classic radar either using
radio waves because you cannot detect
and track something smaller than the
wavelength of light
you're sending at it when you listen to
an FM radio channel those waves all
about three meters large so radar using
them would have problems scene and
tracking something the size of a portion
even millimeter radar isn't good enough
for us not even microwaves all we need
infrared most types of dust and sand
also absorb infrared after reflecting
only a few percent of most wavelength
giving us week for torrents on ave doll
handily many all very effective of about
123 micrometer wavelength which in this
case is what we need so weapons officer
shakes his head and says look captain I
think we can both off court system to
handle this but I can't make a lot of
guarantees maybe we are just stick the
same speed and be happy we can carry a
lot more cargo a lot less fuel than
before
but fuel is cheap she doesn't really
care how much we use any of a million
small comments hanging out of solar
system where plenty of hydrogen even
without meaning to try diving into the
gas giants to get fuel so if there was
any chance of safely shortening the
trips she wants to take them so she
asked the science of so if there are any
options plenty he says but no them are
pretty the captain says she doesn't care
if they take a lot of time to add on and
maintain and he says no so he's being
little most the options just don't
conform to a nice-looking streamline
ship from ancient science fiction
she reminds him that they weren't
planning to enter the ship in a beauty
pageant and since they are going where
no man has gone before
it is unlikely we'd encounter any anyway
and to get on with it
so the first option is to take a lot
more when we're done expanding the ship
its dry weight its weight minus the fuel
for speeding up and slowing down is
going to be around a billion tons of
ship and cargo the fun cross-section the
ship is about 200,000 square meters so
we're making all more out of a big meal
wide metal shell cubes full of hydrogen
being a ton of peace that would only be
20 thousand tons out of a billion during
those five layers thick would only be a
million tonnes tiny holes a few
micrometers thick through a semi love
metal won't League ass fast but over a
century those would empty out easily and
it's awkward patch repair that area with
all the radiation and microneedles
doable but kind of rough so we could set
it up like a conveyor belt the front
isn't a big sheet anymore if the ends of
thousands of little conveyor belts wear
the belt is made up of metal cubes for
the hydrogen they voted out and back in
again and at the back side they get the
payload and about lines out at the front
to provide a few layers of overlapping
all more and we slide a new section
forward whenever one takes an impact let
the robots to do a pales in the real and
keep some space on hand in all these be
airtight just passed close enough that
almost nothing can slip through and
we'll have another layoff more normal
more behind that
in fact will store most of the fuel up
front with habitation sections behind
them if a big collision happens and you
need to replace a big chunk of the
assembly though we have another option
we can shoot a small solar sail ahead of
us itself just a micrometer thick just
launched it and have it on for and act
as a temporary shield most stuff hitting
it is going to spam light through but
fragment a lot or be deflected to the
side just enough he would act a bit like
a nun Burma it would slowly drift back
into the ship from collisions and you
could grab it then and drag it back
inside and recycle it just a 10 foil
thick Shield even if we couldn't recover
it
the total loss of mass would be just a
few tons out of a billion the captain
asks why we can't make that foil shield
nickel and the science also shrugs and
says we can but we will be better off
having several of them ahead of us space
to way out in front not meters or
calamos butthole light seconds ahead of
us
she points out that the front 1 will
just be shoved back into the next one
and so on until they get slammed into
the fund the ship the weapons officer
point that they will also get the way
the ship's radar and leesel so it won't
walk but the Science Officer shakes his
head
we will place them phone up ahead that
the last one is just outside all minimum
engagement distance say a temper second
more than enough time for the ship still
locate target and fire on something that
makes it through but it doesn't matter
because we will keep the shade strung
out at the right distance by pushing on
them with our only source just using md
focused they all a solar sail after all
and we'll put sense of packages on them
to adding a little weight but not much
and we can power those by having a few
solar panels we were target die to use
lasers on when they get scrapped we will
give them a little sideshow and let them
drift back to us on the side and just
snag it and drag it in for the cycling
and the payoff
we are going to put a lot of lasers off
to the side of the ship extending on big
long thin telescope antennas to keep
them originally locked to ship and to
provide power and data flow back to the
ship at the end of those will be a big
laser and radar all giving us a better
section and an angle to shoot at also
yes more easily push things too aside
those telescoping antenna or homes won't
be very massive you have a dozen or so
them telescoping out several kilometers
to the side
really now like the spokes on a wheel if
one gets damaged and they might because
they won't be much shielded you just
reel it back to the ship and repair it
even if one gets snapped up it won't
drift much for fast and you can shoot a
grapple after snatch it and reel it back
in and repair it
we can also shoot curves ahead of us
either with their own pure supply or
pushed and powered by lasers just
expandable things to the text up ahead
of us and maybe even some weapons of
their own even if they each wait several
hundred times we can deploy them on a
regular basis
indeed if we can micro-sized our fusion
drives enough we might want to send me
out ahead of us to slow down and park on
some comet along the way to act as a
fuel supply for a big raid all and
signal relay maybe even with lasers to
help clear path for us or just have them
keep going into a flyball path and
destination we talked about using laser
highways as an author cheap and fast way
of travelling between existing colonized
systems and there's a lot to be said
about laying that down on the original
trip
this would be a good way to get started
if we wanted to and had dr small enough
the head of maintenance complaint
they'll be constantly having to fix
build of a pair stop but the captain
shrugs and points out they are
essentially a massive factory ship and
always have to anyway should be told
this would seem to require very little
personnel she says all right let's do it
and the science officer asked which
system and she says all of them they
wouldn't seem to interfere with each
other or need much mass or energy to
operate and they'll go ahead and scale
the ship up to but only in length
no point anymore cross section to Alma
and defend a ship twice as long
doesn't need twice as much fun two or
more if you're just making it twice as
long
not twice as wide and that means the
same amount of almost still goes twice
as much ship this is a key reason why we
discuss interstellar ships on this
channel I so often treat them as objects
more kinder flying city-states than a
classic small cruise ship of a cast of
half a dozen or even big ones like on
Star Trek with a crew of hundreds we
look at ships that are thousands of
times more massive than modern battle
ships or aircraft carriers crewed by
hundreds of thousands if not millions
not because they need that much crew
they don't the ships would probably
mostly run themselves and just need a
couple dozen people to make decisions
and handle unexpected events even then
only the ship didn't have human level
artificial intelligences on them with in
all likelihood they would or something
smuggle the same kind of automation that
lets you have ships that only need small
cruise or none at all to operate for
decades trillions of kilometers from
home is the kind of automation that lets
you build leviathans like we look at
quite cheaply the problem with smaller
ships especially tiny probes all
manifold and I discussed those more into
space warfare episode but they are they
had the advantage of being hard to
intentionally hit but we are not
expecting to be shot at and by scaling
up in size we benefit in a lot more ways
the small ships need just as much read
all just as many lasers and so on
they also need some sort of power supply
and the fact that matter is that even if
you could make a fusion reactor very
small so it would fit a call it is just
the nature of such devices to be more
efficient with larger there's only a few
realistic options for going faster than
fusion we've discussed them before and
they pretty much all require using
photons or maybe neutrinos as your
rocket exhaust if you have exhaust one
is lethal push ships will being bigger
does help since you're after meals for
getting pushed on can be bigger allowing
more discs
and for those pushing lasers to target
you please let you get very fast so the
rocket equation doesn't apply
no fuel but have the issue of slowing
down requiring either slow down fuel or
something like the interstellar laser
highway we discussed in the interstellar
colonization episode back into your one
another option is black horse tall ships
which we gave a whole episode over to
and those had to be massive ships just
by their very nature as we discuss their
the only serious option for a faster
ship infusion can give you while being
smaller than an aircraft carrier and be
neighbor slowdown is antimatter the main
byproduct of combining battle and
antimatter obvious photons which
obviously have an exhaust velocity of
the speed of light that doesn't mean you
only need an amount of it as implied by
the rocket equation to get me a light
speed though we walked with speed today
and in the past where we could almost
entirely ignore special relativity at
ten percent of Lightspeed you all da
Gama of just point five percent a meter
long object is half a centimeter shorter
your clocks are running slow by about
one second every three minutes or about
seven minutes a day and an object is
just a little more energy to get to that
speed than classical Newtonian equations
say at twenty percent those effects have
jumped up to about 2% amigo is two
centimeters shorter clocks lose about a
second a minute relative to or normal so
a 50-year trip on or scoundrel only took
you 49 and there's a small but
noticeable increase in energy / Newton
even a 50-percent of Lightspeed these
effects on two huge yet they jump to
fifteen percent at eighty-six percent of
Lightspeed they double even your light
speed exhaust velocity is straining to
get you any faster and beginning to need
huge ratios of fuel to ship and cargo
and every object you hit wax into you
with an energy of its mass in anti
matt'll and ninety-four percent is
tripled and ninety-seven percent
quadruped board quintupled at ninety
percent seven times higher at
ninety-nine percent 10 and 99.5 percent
and it keeps getting worse
now at those speeds space really does
have enough drag that you want to be
thinking about aerodynamic shape stew
and nothing could push a ship this fast
as an onboard fuel you carried not even
anti Madol a fuel mass ratios of
thousands to one and you need to
constantly add in more energy just
maintain this speed against that dragged
from space gas and all but the tinies
motes of dust need to be vaporized so
they don't smash your ship like a nuke
you probably need to punch those
molecules with a laser so hold the
ionized so a magnetic field around the
ship might shove them aside and that
would need to be one heck of a magnetic
field and yes most ships probably would
have big magnetic fields because they
will provide a little protection from
anything killing an electric charge and
a decent fraction of the stuff in
interstellar space is ionized or will be
when you're wrapping them with lazers
especially if those are in the
ultraviolet or X range of the spectrum
it won't help with collisions but it
will decrease the ambient radiation from
all the stuff too small to shoot
it's why don't ponder faster-than-light
travel much beyond its dubious nature as
what is basically a mathematical gimmick
it's not like even getting a light speed
is a real option because it requires
have seen expenditures of energy
compared to just going half as fast and
there are other things you can do with
that energy which are better
alternatives then try to get there a bit
faster and happy to employ the kind of
radar systems that would glow like
mature sons and the massive
supercomputers just to track everything
so you aren't annihilated by random
grain of sand those collisions and
radiation begin becoming the real
problem and no cool space drive is going
to magically make those go away your
best bet for real interstellar travel to
places you already been is to have a
large chain of fusion powered laser
relays shoving ships around and
constantly tracking everything in their
court or to keep it free of dangerously
large space dust again that laser
highway even then especially since those
ships need large sales were talking with
lasers
I would never aim for more than
eighty-six percent of Lightspeed scene
for antimatter it just isn't worth going
fast
even if you can produce the substance
for peanuts and stored safely frankly
both all kind of silly speeds anyway you
don't engage in routine interstellar
travel unless you have either biological
immortality or can freeze and thought
people and as i discussed before the
latter ability almost requires the
formal in which case time doesn't matter
much everything still takes many years
that your destination experiences and
you either don't or don't care about it
because you've got as much time as you
want
that's our topic for next week life
extension something we looked at briefly
last year but we'll look at in more
detail so on ship speeds for fusion
depending on how good it gets anywhere
from five to thirty percent of light
speed though the latter is really
pushing it unless you've got some
material that can reflect neutrinos
micro black holes can do better
especially if you can feed them to
Auntie metal and laser sales but
realistically not much of a half to
maybe ninety percent of light speed as
the shape your typical interstellar ship
r2 look like an unsharpened pencil and
as we discussed before the energy needs
to get up to just a tiny fraction of
Lightspeed sold what the energy needed
to operate life support and operations
that even on a wasteful gluttons budget
over centuries they would look like a
round again more compared to your fuel
needs our lasers and massively
overpowered Negev a doll will add to
that but not too much yet while the main
body of the ship might look like a
pencil it will probably have those
frontal foil shield stretching over
millions of kilometers ahead and thin
projections sticking out the side like
spokes on a wheel another reason by the
outer Hall of the ship either does not
spin or does so very slowly
even though you have big rotating
habitats sections inside 250 meter
radius is probably as wide as you've
ever build a ship since that is our
estimate for the widest you need to
maintain or like pseudo gravity that
people didn't get motion sickness from
hopefully by now you've got a pretty
good idea why these social ships never
have maximum speeds put on them almost
always get described as very long and
melo totally different ball game from
interplanetary ships though they'd also
probably be long cylinders with a big
forward shield telescope out ahead of it
and spoke like projections for sensors
and collision Lazar's just scaled down a
lot spaceship designs are never going to
look very cool or maybe we change our
notion of cool after all planes and
sports cars and motorcycles and rockets
are not objectively that cool looking
but we've come to view them that way for
the implied speed and power of the
design
okay we'll start there for today next
week we will look at life extension in
some more detail and look at how that
might actually happen in our lifetimes
along with some of the implications of
that on society we've discussed it
before in bits and pieces but this time
we'll focus down more on the technology
the whores and challenges and the
impacts of it on civilization make sure

Lego Batman is the most plausible Batman of them all | Cape Gliding & Grapple Gun | Physics vs Film - Duration: 5:54.
Batman is pretty damn cool, but a lot of
people have pointed out if he were real
it would be completely absurd. The
physics just does not check out. He'd go
very quickly from being Batman to just
battered man... except for one version of
The Dark Knight.
Yes, lego batman is by far the most plausible
version of the character, putting aside
that little pesky detail that lego minifigs
aren't actually alive.
First up a little detective work, now
lego minifigs are 41mm tall and
given that Batman in the canon of the
comics is 6'2", that means we're
dealing with a world that is almost 46
times smaller than our own. But remember
The Lego Movie was shown to be here on
Earth, because that's the only place in
the universe that Lego exists (that we
know of) so we're going to keep standard
earth values of things like gravity,
density of air etc. so no planet made
completely out of Lego here. Regular
Batman has been attacked by the laws of
Nature on two fronts: gliding with his
cape and soaring to the tops of
buildings using his grapple gun. Let's
start with that cape. Students from the
University of Leicester a couple of years
ago did a feasibility study into
Batman's gliding. Taking into account
gravity, drag, and a generous estimate for
the amount of lift his cape could
provide, they found that Batman would
be approaching the ground had some 80
kilometers an hour just from the top of
a fairly large building.
That sort of velocity is fatal.
But we can't just take that result and
scale it down by some 46 times for lego
batman because the equations of drag and
lift are both coupled and nonlinear when
applied to two dimensions like we have
here. The only way to get a result is from
doing the simulation and so I have
reproduced that Leicester study exactly
but in this time for a lego-sized
batman. Lego batman's terminal velocity is
23 km/h which he achieves in just 10
seconds of flight. This is about the time
it took regular Batman to reach 80.
But bear in mind that if we scaled lego batman
up that 23 km/h would be be just over a
thousand. So does that mean that we've broken
the bat? No, because Lego Batman isn't
made of mere flesh and blood like us
mortals. He's made of acrylonitrile
butadiene styrene, or ABS. This type of plastic is
pretty stiff. It can be squashed by about
2.6%of its dimensions
before it actually starts to deform.
So using that stiffness and assuming
LBM, that's Lego Batman by the way,
comes to a complete stop when landing, which is
the worst-case scenario, the pressure acting
on his feet and legs would be about a
kiloPascal. ABS though has a compressive
strength of 42 megaPascals, so LBM
has survived.
OK so what about that grapple gun then?
Well, people have worked out that not
only would it be a lethal weapon when
Batman tries to catch people with it, it'd
probably end up hurting himself as well.
A measly three feet per square second
acceleration or about a tenth of a g
would put a force on both his hand and arm
equivalent to powerlifting. And if he were
going at some of the rates scene in the
movies, then we're talking at least a
dislocated shoulder if not a severed
limb. But again
LBM isn't as puny as he looks.
Given the strength of ABS and the area
of a minifig arm, lego batman could
withstand accelerations up to a hundred
and thirty thousand meters per second
squared.
That means he could ascend to the top of a
to-scale LEGO model of the Empire State
Building in 0.08 seconds.
That is impressive. But there's one thing
about lego batman that wouldn't be that
impressive and that is his voice. "Because
I'm Batman". Sorry WIll Arnett, but you
should be sounding a bit more like this.
But in all other respects lego batman is
totally badass!
hey guys and gals thank you so much for
watching this lego batman video, I hope
you enjoyed it. Don't forget please
subscribe to my channel if you want to
get more stuff from me, I do physics
videos every other Thursday, and you can
share this video around that would be a

Why I Found Among Others Offensive | Book Review [CC] - Duration: 6:03.
hey there booktube Katie here and you're watching
Katie Loves to Read. Today we're going to
talk about a very problematic book that
really upset me and that was Among Others
by Jo Walton. Let's start with a brief
plot summary for those of you who don't
know what this nebula winning fantasy
novel is about. It's about a young girl
who is Welsh and her mother is basically
this super evil witch who she has
defeated and in defeating her mother her
twin sister has died and this has left
the young girl with a disability so she
walks with a stick andthis aspect of the book his own
voices because Jo Walton herself has
the same disability as the main
character. And this character runs away
from home and ends up living with her
estranged father but her estranged
father on her aunts decide to send her
off to boarding school in England where she
is the only Welsh girl and while she is
at boarding school she sometimes talks
to fairies but mostly she just reads
science fiction and fantasy books, like
seriously that's pretty much all that happens.
Oh apart from the parts of the story
where she discriminates against Irish
people, basically says that Ireland is
full of shit and that she doesn't like Irish people
and that my culture is worthless. Yeah can
sense maybe what was problematic for me?
So yeah this book it won many awards,
it's generally loved when I looked
through goodreads, most of my friends had
given it four or five stars. There was the
occasional person who's given it one star,
they were bored and I guess that because
it was a slow story but I can appreciate
a slow story sometimes but there were
just these kind of underhand snide
little remarks that were made throughout
this book about Irish people and at
first I tried to brush them off.
I tried to just say Katie you're reading
into this too much.
It's it's not that bad that she says oh it's a
pity the one Irish character that we
have in this book is so stupid and dull
because that's just a stereotype of Irish
people and I'm like and I'm sorry is it?
Are we stereotypically stupid? And of
course what my brain is running to then
is this kind of stereotype of Irish
people that British people had that
was used as a justification to invade
my land take all of the land of Irish
people and give it to white English
Protestants and to oppress my people for
centuries because we were called "savages".
Now this was not used to massacre us in
the same way that it was used to
massacre many indigenous people who are
non-white around the world, so up
front I will admit that, but that's what
it's, it's got ticking in my head is
that kind of savages thing. That kind of
we're superior because we're English and
therefore we can invade wherever the
fuck we want to because we're English.
Now
Irish-English relations are much better
these days because I will give you this so even though
this Welsh author is making this snide
remark I'm going ok give her the benefit
of the doubt. She's Celtic firstly so you
know there's some kind of camaraderie
among Celts and she probably doesn't mean
it.
She probably doesn't mean it but then i
hit eighty percent of the way through
the book ish, I think where she's talking
about our main characters in the library
and she's filing the books away with the
librarian shelving them and she's shelving books
that you would never touch with a
bargepole because they're just not her
type thing. They're not science fiction
in fact they are "problem books", they are
books with people who have problems;
bouts about kids with drug addictions or
parent who abuse them or books about
people who live in Ireland? I did a
double take at that point *nonsensical mumbling* - what?
I'm sorry its its as bad to live here as it
is to have an abusive parent,
ok cool - just no just no. And then
that had me reflecting on the whole book
because the one Irish character who I
mentioned before she is literally just
used as a stupid plot point throughout.
She has no brain of her own she
literally is just there to make the other
character look good and be incredibly
loyal. So for example there's a poetry
contest that goes on during this book and
this character Deirdre comes up and
asks our main character 'will you write
my poem for me,
you're really good at poetry and I can't
do it by myself' and her poem wins. So she's
this person who like profits off other
people's intelligence, is really bad
all of her respective classes but the
only other standout trait this girl
has apart from being from Ireland
is that she's loyal. And then this is other
encounter where the two girls get in
trouble,
the Irish girl and the Welsh gir,l and
the main character makes this
observation 'well you know be worse for
her to be expelled cause she'd have to go
back to Ireland and that would be really
shit' and it's like this constantly
snide under current but also the way
that character is used that makes me
think it's not just the perspective of
our main character that Ireland
is shit which presumably people out there have
that perspective.
I don't want to have to talk to them but
i know they must exist but it's the way
in which his character is used that
makes me think this is the perspective
of the author and I honestly can't
believe that this discriminatory content
has not been called out up until this
point and I think I'm angrier because i
was expecting to love this book so much.
But yes that's my rant about Among Others,
it's up to you whether you want to read
it obviously but if you do please
be on the lookout for the content and be
aware that it's a problem and that viewing
Irish people in this way is a problem
and it reinforces stereotypes of Irish
people that have been around 4 about 8 and a half
centuries now yeah. Remember we had seven
and a half centuries of British
occupation and persecution and that
these stories are hurtful and for that
reason i gave this book a one out of
five stars. if I could have given a zero
I would've. I'm still not a hundred percent
sure why I finished it. It really hurt me
to read this so i'm going to stop now
because it's just going to get into a
rambling angry
Katie rant and I don't want to go
there but thank you guys for watching
and I will see you in my next video bye!
