Dipole, bipole and omnidirectional speakers - Duration: 14:06.Most speakers radiate sound from the front.
Apparently that seems to work the best.
Or does it.
Then why are there also speakers that radiate from the front and the back and even speakers
that radiate in all directions equally?
Let me start with a clear statement: whatever you choose, there will be no best way.
There might be 'a best way' for you and your listening environment.
At least, to your judgement.
And the same goes for me.
There is no way we can reproduce the exact acoustic situation from the concert hall in
your listening room.
That would even be highly undesirable in most cases, given the loudness levels.
What you can achieve is have your brain believe it is experiencing the live event.
To do this, Alan Blumlein developed his binaural sound system in the thirties of the previous
century.
This system is now known as 'stereo' and uses two channels of audio that contain spatial
information in the form of spectral, loudness and time clues.
An instrument on the right side of the orchestra will sound less loud, less bright and slightly
delayed in the left speaker than in the right speaker.
And so on.
It is this kind of information that makes our brain believe there is a hall between
and behind the speakers.
How does this work?
I will try to keep this comprehensible and thus will simplify things somewhat.
Let's see what happens in a live environment, an orchestra in a concert hall.
When the orchestra starts playing, the sound will not only travel directly to your ears
but also via reflections on the walls and ceiling.
The direct sound reaches your ears the earliest since it had to travel the shortest distance.
Then there is a group of reflections that took the shortest way via walls and ceiling.
These are called early reflections and by definition take 30 milliseconds or less to
reach your ears.
After that the sound that has been bouncing through the hall will reach you.
This is called reverberation and is more dense than the early reflections but lower in level
and more coloured by losses in the air and the texture of the boundries.
The spacing of reflections and the spectral balance of it will influence how we experience
the hall.
Sound travels at about 334 meters per second so the latest early reflections at 30 milliseconds
have traveled about 11 meters more than the direct sound.
I don't know how big your house is, but in my room that would be rather impossible.
A clear proof that a concert hall differs greatly from a living room and that trying
to reproduce the exact physics of a concert hall in the living is far from realistic.
And not necessary either.
Our hearing or rather our auditory system distills a lot of information from temporal
clues in the sound.
It triggers on the flanks of a sound wave and integrates the first 5 milliseconds to
determine localisation and tonal balance.
It is therefore of eminent importance to prevent early reflections in your listening room that
follow the direct sound at only 5 milliseconds or less.
Sound travels about 1.7 meters in 5 milliseconds and it's easy to determine the time difference
between the direct sound and the first reflection using a string, as I have described in my
Loudspeaker Placement video.
The link is in the show notes.
Acousticians often prefer to have a greater difference in arrival time between the direct
sound and the first reflection: at least 10 milliseconds, preferably double or more.
But it's not only time that's of importance, the level and spectral balance is too.
The louder the reflected sound, the more critical the time difference becomes to the direct
sound and the same goes for the brightness of the sound.
And now we get to the subject of this video.
Most speaker systems only have drivers on the front and therefore will radiate sound
forwards for as long as the sound waves are effectively blocked to go backwards.
This only goes for mid- and high frequencies.
Low frequencies radiate omnidirectional, so in all directions.
They simply fold around the cabinet.
The idea behind omnidirectional speakers is that, since the lows are omnidirectional,
you better make the mids and highs omnidirectional as well so that the sound towards the walls
has the same spectral balance as the direct sound.
Conventional unidirectional speakers not only block mids and highs backwards but also have
a frequency dependent dispersion towards the front.
Where a mid range speaker can have a 60 degree dispersion at 500 Hz, it might narrow to - say
- 15 degrees at 2000 Hz.
The tweeter then takes over having a wider dispersion again.
Therefore the off axis response of normal speakers is always coloured to some degree.
This gave some developers at the end of the sixties the idea to have a speaker radiate
the same frequency spectrum towards the walls as to the front.
In the book Music, Acoustics & Architecture, Dr. Leo Beranek wrote that in a concert hall
the sound that reaches the ears of the concert goer is predominantly reflected sound and
that therefore loudspeakers should radiate in all directions equally.
There seems to have been a wide interest in this in and around Boston at that time.
A respected name then was Roy Allison who passed away only last year.
He was a audio journalist up to 1959 when he started working for loudspeaker manufacturer
Acoustic Research.
He there was involved in developing the much appreciated AR speakers like the AR-3A and
- important in this perspective - the AR LST.
He left in 1972 and researched the interaction between the loudspeaker and the room and published
about it.
He then founded Allison Acoustics Inc and made the well respected Allison One loudspeaker.
The LST and One were not omnidirection, they needed to be placed against the wall to avoid
reflections from the wall.
But the angled mounting of the mid and high speaker units made a wide dispersion possible
towards the side walls.
Another well known name from that era is dr.
Amar Bose that studied psycho acoustics and electrical engineering and was convinced that
when sound was radiated mainly towards the wall, it would sound far more natural.
So he developed a speaker that only radiated 11% of the sound towards the listener and
89% towards the rear wall.
Het used 9 identical wide band speakers and used an equalizer to force them to a wide
frequency response.
Therefore a powerful amp was needed but then the sound was impressive and emerging, although
not super precise.
Around that time there was also a Scandinavian manufacturer that built a speaker that had
several midrange speakers and tweeters mounted on the top of the cabinet in a way that the
sound was spread in all directions.
Other brands that made omni's: Harman Kardon, Hegeman, Morrison Audio,Tannoy and even Akai.
The idea never led to great popularity but still a number of brands manufacture them:
Mirage, MLB, Duevel, Temporal Coherence and others.
Most of these use a deflector for each driver to spread the audio in all directions.
A variant on this is the bipolar speaker.
This type of speaker has drivers on two sides playing in phase.
It adheres to the same ideal as the omni but with simpler construction.
The number of manufacturers and models is limited unless you want surround speakers.
Where I use the Mirage omnidirectional speakers for surround, many use bipolar speakers, more
or less constructed like the Allison One, only smaller.
The idea is that you don't need pinpoint precision but an ambient sound field for surround.
The front speakers play the main part where placement is concerned.
Where the omni directional en bipolar speakers had their radiation pattern as a design goal,
bipolar speakers have their radiation pattern as a result of the technique used.
For the dipolar speakers I know use a large membrane that radiates on two sides: the electrostatic
speaker and the magneto static speaker.
Both use a thin sheet of plastics - often mylar - that is moved by either electrostatic
or magnetic force.
When that membrane moves forwards, a positive pressure is caused in front of the speaker
while at the same time at the rear there is an equally strong negative pressure.
In other words front and rear are out of phase resulting in no output on the sides since
there front and rear pressures cancel out each other.
This is an interesting technique since it causes the same audio spectrum and pressure
to the front and the rear, making the tonal balance of the reflected sound only dependent
of the wall material.
But where omnidirectional speakers also radiate the same sound to the side walls, where the
most early reflections will come from, the dipole speaker does not radiate to the sides
so that, when those sides are aimed more or less at the point of first reflection, early
reflections can be controlled effectively.
Using omnidirectional or bipolar speakers in an average size room will create lots of
early reflections very close after the direct sound.
This makes localisation quite difficult.
But if you have the space to place the speakers some meters from the walls, it can lead to
a very spacious and powerful sound image.
Getting the pinpoint location many audiophiles search for, will remain more difficult with
this type of speakers.
Dipole speakers provide a lot of the benefits of omnidirectional speakers and can offer
good localisation due to the 'dead' sides'.
They still need 2 meters distance from the wall they are in front of but the distance
to the side walls is less critical.
And both electrostatic and magneto static speakers aren't the cheapest and do need
an amplifier that can drive them properly.
Loudspeaker placement is of great influence to the sound with any speaker but even more
so with omni's and bipolar speakers.
Dipolar speakers might be a fair way in-between if you can live with the size and price of
large panel speakers.
The luscious, spacious sound all three types can generate does have it share of fans.
But those searching for strongly focussed instruments with pinpoint precision should
not look here.
Again, it is a matter of preferences and priorities.
I have played with electrostatic speakers by Quad, Van Medevoort and MartinLogan for
years.
Currently I use 'conventional speakers' by AudioPhysic for in the end I chose for
precision.
Although, 'in the end' sound too definitive.
If I find a speaker that pleases me more, that has a different approach and fits my
budget at that time, I might switch again.
And I sure I'll let you know.

SEE THE WORLD 22: Trans Ecuador Mountain Bike Route (part 2) - Duration: 51:31.previously in Ecuador
I started the Trans Ecuador Mountain Bike Route three months ago
having spent almost a year in Colombia, it felt like leaving home
but soon I met the locals
the travelers you forgot the camera
and of course, the dogs
you are a spoiled dog, eat the pizza!
although the cows often tried to make things hard
I made it through the smallest trails and into the volcanic corridor
where the white giants stand tall over the windswept eternal pastures
where the horses run free
and so do the deers and the cows
fight, fight
hey, not me!
September 2017, near Ambato, Ecuador
it took half a day to escape the city and I was back home into the cold highlands
away from it all and waiting to see what comes next
SEE THE WORLD episode 22 Trans Ecuador Mountain Bike Route (Part 2)
so we are off to a good start, I got all my intel for the trail
we´ve got a handmade map on the road and we are good to go
and i cant see anything
protected area, do not throw garbage
the good news, is that I found the road
and the bad news is this is not a road
so right now, really bumpy cow stuff and mud}
but we are going over there and after that its all downhill
there is a cow and a baby over there and they are confused
like what is this thing up there on the trail and they are starting to run
because they dont know
finally a trail of some sorts
look at that beauty of a trail
unbelievable
hey horse friend, how are you?
oh there is another one, hello! ooo he is afraid
as usual, the friendliest natives in Ecuador
now we are passing the chicken farm
there´s three chickens and two piglets and they are little ones
three horses and a cow
and we are continuing on what appears... hold on...
yup, that´s a car track and a road, a real road
big thanks to the Ecuadorian department of transportation for this beautiful experience
and despite the windy days I always wanted to look for the perfect sunset
to see the yellow and red stretch for miles across the clouds
all the way to the Pacific Ocean
the roads were very busy!
look at that dog, he is so quick
hello my friend, where are you going?
you are my sunshine, my only sunshine
you make me happy when skies are gray
tanananana thats why I love you
what do you think?
llamas have no feelings hearts of ice
I´m watching you little mister
dont you dare sniff my camp when i am not around
thats right, run away
tail between your legs
ecuadorian poodles
it´s a great mystery
these wild animals
roam the forests, protect the innocent
...and pee on peoples bikes, right buddy? that was not nice of you
not nice at all and you know it
but he is a friend
we get along now
but we havent gotten to the petting stage come here, come
when the food comes out, then we become real friends
I´m watching you I´m watching you, what are you doing over there?
ah yeah you like it! you like it!
good morning
what is your name?
there are the merciless winds in the summer and the downpours in winter
but somehow, people manage to live and work here
the dogs watch with suspicion
as the road makes the impossible climb into the wind
at the pass, the clouds finally reveal the closest point to the sun, Volcan Chimborazo
funny, very funny looking llamas
i follow the road north to an old schoolhous
which offers just the right views and wind protection for a night at 4200 meters
I think this sign raises more questions than it answers
why did they leave their friend on the other side of the river
who is he, why is he wearing red?
and what are his hopes and dreams
is he also searching for the freedom in the open skies and the wild lands of the Andes
i cant tell if its a dog or a fox or a coyote
could that be another volcano???
hey there spotted dog, come here
this amazing spot, just off the road
it´s flat and it´s gonna be a nice sunset
if the clouds clear we can see chimborazo over there in the distance
and we´ve got medium protection from the wind
why not, i have some time to make hot chocolate and take some photos
and do something i am very good at, and thats nothing
trans ecuador mountain bike route
moving slowly south towards peru
and eventually we get there
and then bolivia and argentina and chile
and there was something about the freedom that you get when traveling by bike and no time limit
you can stop anywhere and make your house, your food and spend the day looking at the clouds
you can watch the last light fade from the sky
and stand outside at night knowing that no photo can capture the billions of stars shining in the sky
you have nice dreads buddy
there you have it, ecuadorian poodle in the wild
baby donkeys have got to be the cutest thing ever!
hello, hello to you too
hey buddy, what are you eating?
more cows, resting in the sun
hey get back to work back to work, start eating gras. Gogogogo
they dont listen
and i´m going over there down in that valley
and up again towards a lake hopefully
there´s a lot of donkeys here... we can maybe
recruit them for my army
hey donkey, would you like to join me and conquer the world?
yeah? lets go! he´s coming
good, we got one coming with me now can we convince the others
so I have a little bit of a problem with the front brake
the pressure is too low
so I stuffed some of my stove windscreen under the brake pads
because i still have brake pads but the problem is that there is no pressure
so fingers crossed, this contraption will work, at least for the inca trail
because there is no way I can do the inca trail without a front brake
like i´ll have to push my bike down the hill
so we are taking a day off a day off to drink 3 in 1 nescafe
which is actually surprisingly good
little bit of sunshine right now
it rained quite a bit in the morning
the town nearby has a store where I can buy potatoes
so I will be good for the next 3 or 4 days
but today is just resting and sunshine
no matter how far I went it was hard to avoid the graze of Chimborazo
standing far and high amongst the clouds
in a last effort to escape, I aimer up across the Ecuadorian Inca Trail
i am supposed to go up this... somewhere... somehow
my friends on the horses so much better way to travel, look at them!
progress was hard and slow but nothing can stop the wheel that keeps the travelers travelling on
not the cliffs, the rain or the cold
a little price to pay for the privilege of following the endless ridges home
so the good news is that I was told that the trail will vastly improve
and the bad news is that the person who told me rode a horse
sadly the only thing Ecuador is not good at is bike parts
the steep roads and trails of the bike route
eat brakepads for breakfast
the cost of which can be 3 to 10 times more than in other places
the best solution was to fabricate a pair from a motorcycle brake pad and hope the glue will hold until Peru
i rode past Cuenca and up into the mountains looking for the best sunsets
the lower altitudes meant warmer weather more people and more dogs
and the typical countryside life I have grown to like
so if you ask me what the weather is like right now...
i think i will just say, a little bit of everything
we´ve got headwind, cold rain,
sunshine and also a very interesting road
we have been upgraded to horizontal rain!
but also, amazingly beautiful
you can clearly see, middle of nowhere
the Japanese are building bridges in Ecuador
and uh, they just like building bridges the Japanese
I´ve seen bridges in Nicaragua by the Japanese, in Panama...
so I can just feel my fingers enough to pull my brake levers
but I´m gonna have to set up camp somewhere
just so you dont get the wrong impression not everybody rides horses and donkeys in Ecuador
they have traffic lights, cities and cars and I think hot water
but I feel like fish on land there and I often zip through them
although they are not bad places I just could never capture their unique atmosphere
but from far away, they seem nicer, quieter and that is where I like to be
the bike is hard to ride!
easier with sombrero
my front brake pad melted off due to overheating
so I went on the truck down the hill ending the Trans Ecuador Mountain Bike Route in Style!!!
I rested for a day in Vilcabamba and did laundry
the remaining brake pad got smoked down one hill
so I rode uphill but tried to take cars going downhill
until I realized I can stop with my feet!!!

Guitar tip 01 left hand thumb position - Duration: 3:05.Hi Stuart Bahn here and this is a first in a series of guitar tips videos.
In this video tip one is to do with the left hand thumb position. When you play a
bar chord like this your thumb position ought to be something like that so in
other words approximately in line with the first finger.
We all have slightly different dimension hands so yours may be slightly more this
way or slightly more that way. It should not be sideways. Why not? Well reason one
I would say is because none of the world's great guitar players do that - or
almost none of them. The second reason is that this just isn't good mechanics.
We generally want to play with maximum efficiency, unless there's a good
reason, on guitar, and having the thumb and the fingers in line means they can
operate very efficiently with the thumb here the fingers dancing around the
opposite side of the neck. When you have your thumb sideways you can't quite do
that. You end up having to, to some degree, rely on some leverage from the wrist.
That's not good technique and that could easily lead to pain in future, as you
clock up more and more hundreds or thousands of hours of guitar playing.
So modelling our playing on the world's great guitar players, there is plenty of reason
to do it like this. If you currently use your thumb sideways, like that, I
encourage you to change that. It can be frustrating, changing technique, but it's
necessary. We all have to do it. I've had to change my technique lots of times over
the years. Unfortunately for most of us, the way that we happen to play in our
early days is not usually the best way. So we all have to go through this
process. So all you've got to do is just repeat it. Force yourself to do this
Barre chord; don't get distracted by playing songs
just play the chord, then reposition it, then reposition it somewhere else.
Try different bar chords, say the shape four bar chord, still with the thumb
around the back like that. Now the same is true for certain scales - not all of them.
When we're playing blues we tend to have a thumb over the top - certainly for
when we're playing the thinnest strings. there's fine; that's how blues
playing is done; there's tons of bending in it. If we were doing a bigger scale
such as this... then I would again have my thumb approximately - well in this case -
somewhere between fingers 1 and 2; still in the same region; not sideways.
OK, I hope that's helpful. If you have your thumb sideways do embrace the
change. Try to get used to it. It doesn't take that long though it is frustrating .
I hope you found that tip helpful. Please give a thumbs up if you did and subscribe
so I can send you more in the future. See you in the next video.

Prague's nickname is: The Best Beer City of Europe.
So, we are in... -Prague.
We have to roll up our sleeves. -Yes, because it's a tie.
We're going to win. That's the only thing I'll be doing today.
Last time we won, and I really liked that.
A new list with challenges. Easy ones for less points, difficult ones for more.
We're in Prague. -Beautiful. The score is 1-1.
Last time you lost and you'll lose today. -Definitely not. Let's see.
Oh dear, nice. Bye bye. -Success.
Sit down, honey.
Drink the local beer. -Staropramen.
Earn about five euros by making portraits at the Karelsbrug.
A message on the Lennon Wall. -Get a tour at the sex museum.
First I want to get points by doing easy challenges...
and then get fifty points for tube gliding and ski jumping.
That's how we'll win this. -I agree.
I think we're wasting time.
Do we have a plan? -Yes. We begin. That's a good plan.
With those wise words, we begin.
This is inviting. -Free hugs, free hugs.
Tony, this doesn't seem to be working.
You're standing like this. 'Let me rape you.' No, sorry. Bye.
Thank you very much. So much love, I like it.
Oh yeah. -Eight points in the pocket. Super.
Both teams won their first points. Time for a beer.
This is it.
We're going to drink that beer for five points. Not much, but it's quick.
Drink the local beer of Prague. -For five points. Cheers, honey.
Show me your beer moustache. Nice.
Not a fine look, Sophie. But it's points. So...
Off to the skate park.
I'm going to try to do an Ollie. You'll fall on your face with that one.
Do I do it good? -No.
Yes, that's it.
In Iraq they call me Nesim Hawk, but in the Netherlands I'm just a dork.
Great. -Have a nice day.
We're at the sex museum to do three things. Go inside, that's one.
Get a tour guide and make him laugh four times.
That was smile one. -Thank you very much.
Oh, my goodness. Do you have one at home?
That's number two.
Don't you think it's nice you can watch porn during your working hours?
To be honest with you, I never saw all the movies. Have fun.
Too bad, Nesim and Marije, we have this and you don't.
Is this for sale?
I see all kinds of objects I didn't know existed in that time.
And we completed our challenge.
The tour, the sex museum with the guide. Fifteen points for daddy.
We can get fifteen points by taking a ride in a supercar.
Like a gold-digger. You can do that.
Too bad I'm not wearing a skirt. -We all regret that.
First I have to find a car with a driver in it.
It looks like she's selling her body. Standing there like a prostitute.
But she's fixing us a car.
I did it. I'm in a Lexus, I think?
But for her safety, shouldn't there be someone with her?
We're in Prague and she gets in a random car.
Nice car by the way.
She just does it. -Good job. In the pocket. Tops.
It says: Find the largest Crawling Babies and take a photo. Three, two, one.
We have this one. Now, yellow penguins. Around the corner.
What do you think? -Love them.
Three, two, one. Five points. Let's go.
We're going to get a haircut. But we have to ask in Czech, not in Dutch.
If I would like to cut the hair? -Yes, exactly.
Look at that. Great.
Sir, thank you very much. Have a nice day. -Thank you.
How do you like my new cut? -I love it. Looks good.
Time is short.
The final challenge is paragliding. I don't know. But we have twenty minutes.
Tube gliding, Tony. -Seventeen minutes left.
While you're in a hurry, the other team isn't.
We just ordered Svickova. It's a traditional Czech dish.
It's tenderloin. So the best parts of a cow.
You take a look at the plate, then I'll take a photo of the clock.
It's busy here. Camera ready.
Well, we've seen the clock. I took a photo of it. Easy points.
Oh, now I see.
Milzink, come on. You get a tube.
Here it is. You're coming, Milzink?
Watch your blood pressure, Tony.
Alright, good luck with doing the dishes. I'll watch.
We are done with our plate. It was wonderful. Thank you very much.
Is it possible now that we wash it?
It was great. -It was great, thank you very much.
Very good. -Nice.
You can hire me. -In a next life I will marry you.
Thank you.
I think, if I'm right... -We did it.
We scored ten points and we have ten minutes left for a challenge.
Okay, helmets on. -Good luck, Milzink.
That's twenty points. Nice.
People look at me like: Is she alright?
What is the best product that you sell?
That was a fail. He didn't want us to film and he didn't give us anything.
Okay, time's up. Sadly the last challenge failed.
But overall we have quite a lot of points. I'm not saying we've won yet...
I have a good feeling.
Come here, honey. Tell me. -Twenty points for tube gliding.
I think with these twenty points... -We might win.
I wonder how much the other team has. I'm bushed. Let's go.
There's only one way to find out.
What's up? You look happy. -I'm tired. Why is it all so complicated?
You get to go first today. -I'll tell you, we have 89 points.
That response means... -Painful.
89. -We have a little more, 124.
That hurts. -That hurts a lot.
I can only shake your hand.
The hunt is over. Nesim and Marije take back the lead.
That's thirty minutes. They have a fifteen minutes' lead.
Thank you for watching. Did you like this video, give us a thumbs up.
And tell us what your favourite team is. -Team Winning. That's us.
And subscribe to our channel. -See you next week in Lisbon. Bye bye.
Lisbon it is.
Curious for the new challenges and the next winner?
Then don't miss it.

Can Humans Live Without A Heart? - Duration: 4:36.This video is part of an exciting collaboration with second thought.
Make sure you watch their video after this one.
The heart is a vital organ in the body.
Usually people are pronounced dead when their heart stops beating.
So, what if we didn't have one?
Hello and welcome back to Life's Biggest Questions, I am Rebecca Felgate and today
we're asking, can you live without a heart.
Before we jump into this big biological answer for you, I want to check that you guys are
subscribed to our channel and if you are, then have you clicked that notification bell?
If you haven't, click that big beautiful bell and make sure you're the first to hear
answers to our Life's Biggest Questions.
Hearts keep humans and most animals alive.
We breathe in Oxygen which is diffused into our blood from cells in our body.
The heart works by pumping oxygenated blood around the body, keeping it alive and healthy.
It also works to pump away all of the carbon dioxide produced when we breathe in too, pumping
deoxygenated air to the lungs, which is defused in the walls of the alveoli, ready to be exhaled.
Our heart is crucial control centre in the natural machine that is our body.
Without it, the body would have no way of transporting blood and oxygen, which would
mean organs, including the brain, would die and our blood would congeal.
The longest we can survive without the heart pumping blood around the body is approximately
4 minutes.
This is the amount of time the brain can go without oxygen before brain cells start dying.
This is why some people revived after 4 minutes live, but suffer severe brain damage.
In short, we can live without a heart for little under 5 minutes….
UNLESS….
Well… that is the big unless ladies and gentlemen, because once again science makes
the impossible possible…there is a small handful of people who have lived without heart.
The concept of artificial hearts has been discussed and experimented on by scientists
since 1937 when an artificial heart was inserted into a dog by Soviet scientists.
More recently, Doctors started testing a continuous flow device in a number of cows.
This was a heart like contraption that used blades to control and circulate blood flow.
In 2011, this device was installed into a very ill patient, Craig Lewis, who was suffering
with a heart condition and was told he was about to die.
When the Continuous Flow Device was installed into 55 year old Lewis, he became the world's
first heartless man.
When Doctors listened to his chest he had no pulse, but blood was being pumped around
his body allowing him to live.
Sadly, he did die after 5 weeks, but this was as a result of underlying health issues.
A bigger success story, while waiting for a heart transplant, fitness model Andrew Jones,
had an artificial heart and pacemaker in a backpack.
Not only was he living without a heart, he managed to maintain a fit body, which is incredible.
He once said "I'm pretty much the best looking zombie you'll ever see."
Similarly, a 25 year old American called Stan Larkin lived with an artificial heart for
almost 2 years before receiving a heart.
There are some species that don't need hearts.
Jellyfish, for example, don't have hearts, nor do sponges, or flatworms.
These animals have other circulatory systems, but as humans do not work in this way.
So, in answer to our question, humans can indeed live without hearts so long as they
have a heart like device that is able to pump blood in a way that a heart would do however
at the moment these seem only temporary fixes for people awaiting transplants.
Although, as with all medical advancements, who knows what the future of science may hold.
Perhaps one day we will create an artificial heart good enough to allow us to live without
a real one.
So, that is one big question answered for you.
What would you like to ask us next?
Our Patreon members are able to suggest new videos for us to make, so there is a link
to that in the description box below.
Thanks for tuning into this video!
I am Rebecca Felgate, I'll catch you in the next video but for now make sure you like
this video, and of course, stay curious, stay alert and never ever stop questioning.
Thanks for watching to the end of this video!

10 GREAT Ways To Style Up Christmas | STOP Wearing Ugly Holiday Sweaters - Duration: 8:48.10 GREAT Ways To Style Up Christmas | STOP Wearing Ugly Holiday Sweaters
[0:00:00] Here's the deal, guys, if I catch you this
holiday season wearing an ugly sweater, wearing a novelty necktie, wearing weird belts, guys,
I'm going to ban you from my channel.
No, I'm not going to do that.
Well, maybe I might, but I think you guys get the point.
I want to give you ten items that you could wear confidently with style and be the best-dressed
man this holiday season.
[Music] Now, hopefully from that intro, you don't
think I'm the Grinch.
And I love a great holiday party, but I want you to be able to walk into the room and be
the best-dressed man in that room.
You can do that still have that holiday spirit with these items I'm about to get into.
Item number one on the list, have a signature seasonal jacket that you wear and whose color
whose texture, the overall look of the jacket it just sends that signal of the holiday season.
Now, I could try to pull it off with this jacket right here.
You guys have seen me wear me this throughout the year in multiple videos, but I don't
wear this jacket out very often.
And, what is great for a signature jacket is one that isn't going to look like you're
normal dark gray, it's not going to be your dark blue.
This is going to be something that definitely stands out from the crowd.
But, at those holiday parties, that's what you want to do.
For me, you could even go with a dark red.
Yes, I said a dark red jacket.
There are blazers that are made like that, but most likely if you wanted to have something
really nice, you probably have to made it – get it made custom, maybe even use a flannel.
I have a number of dark green jackets that you've seen on my videos, but you have to
go to a specialty store.
You may have to have something custom-made.
Now, what I'm not talking about are those novelty suits out there.
You know what I'm talking about.
They've have candy canes on them, maybe snowflakes, they're in that green and red
color.
And I applaud the guys that pull that off, have fun at their company parties, but that's
not going to be timeless or classic.
What I'm looking for you is to get a jacket maybe a sports coat that is something that
you could pull off at these company parties.
But, if you so choose, you can actually wear it to other events.
Next up, I've got sweaters and I'm not talking those ugly sweaters.
I'm talking classic sweaters that come from places like Ireland that come from Peru.
And oftentimes, what you're going to see here are small repeating patterns.
So, let's take a look at the Fair Isle sweater.
Pretty nice, right?
And this right here you can wear into a company party, it's going to look great.
You can find a Peruvian sweater, a lot of the different patterns in here.
They actually have a long history behind them.
Another option, gentlemen, is the classic Aran sweater especially in white or other
lighter colors.
This for me just symbolizes it has a feel of the holiday season.
Other times, sweater like this, notice the knots going in and around the chest and the
buttons.
The buttons here are oversized.
For me, all of these just gives a feel of the holiday season.
All right, gents, for this next point, let's interject some fun into this video.
Everything I've talked about before classic conservative.
Now, let's bring in some novelty underwear.
Yeah, okay.
So, I gave a little bit of crap to the novelty necktie just because it's right on your
chest.
This, you've got a little bit hidden, no one's going to see that.
Well, no one that you don't want to allow.
But, you wear this, oh, yeah, you've got the holiday spirit going.
Who doesn't look – who doesn't love gingerbread man?
Now, guys, all the underwear I'm about to show you brought to you by MeUndies.
They're the paid sponsor of today's video and they're a great deal.
I'm going to link to them down in the description.
And all the underwear I'm about to show you, I want to hear who wants it down in the
comments.
All you have to do is let me know what is the particular name of the underwear and name
the size.
They sent me all these underwear and a lot of it is just not my size.
It is new, I promise.
A lot of it still has the tags on it.
So, this one right here, what do you think of this?
Pretty classic, pretty conservative, but the pattern and the color to me says, hey, this
is for the Christmas spirit.
All right.
This one, I really like, but they sent the wrong size for me, so I'm going to send
one to one of you guys over there.
All right.
What do you think?
Pretty nice?
Another one right here.
Guys, all you have to do let me know down in the comments the particular name and the
size because who says you can't wear pink and penguins at the same time.
I'd be putting this stuff off.
So, I love MeUndies because they use Micro Modal.
Micro Modal if you're not familiar, it's three times softer than cotton.
Having worn their underwear now for about four months, I can tell you it's one of
the best deals in underwear out there.
Check out their subscription service.
I think that really just makes it a no-brainer.
I'm linking to them down in the description, guys.
Go check them out.
Good company.
Next up, gents, we've got bowties.
And if you've never worn a bowtie, you don't know what you're missing, guys.
Bowties are one of the most fun men's accessory items to wear.
Now, bowties are just as formal as any type of necktie out there.
In the same collar, but bowties they have some big advantages.
One is they're incredibly uncommon, so it's something that you can wear and you can stand
out from the crowd.
Two, they actually look great with small repeating patterns.
So, if you go with a novelty bowtie with a small maybe candy cane or something from a
distance you can actually pick up what it is, it's a great I think accessory to pull
off and it looks so much better than a long novelty necktie.
[0:04:59] Now, another thing about the bowtie is people
want to come up and talk to you because bowties make you approachable.
Bowties make it so people smile at you.
Can you get mad can you start a fight with a guy in bowtie?
So, bowties guys are where it's at and I highly advice you try wearing one this holiday
season.
Items five and six are both holiday-themed accessories.
We're talking about cufflinks and we're talking about tie bars.
What's nice about both of these is that they kind of fly under the radar.
A lot of times people especially when you're just walking by they're not going to notice
them, so you can wear something that's maybe a little bit outlandish.
Maybe something that is a little bit more attention grabbing something that you wouldn't
wear on a full necktie you wouldn't wear, you know, a bright outlandish suit.
But, you would maybe want to wear something, yeah, you want to have fun, Rudolph the red
nose reindeer.
Maybe you loved him as a kid where you can wear those cuff links.
You have something you really love, Santa Claus, you still believe in the guy, so you
want to wear him on your tie bar.
Whatever it may be, guys, you can bring into those accessories because they, again, fly
under the radar so you can have a little bit more fun with them.
Holiday item number seven, let's get back to the classics.
So, bring in a dark pair of brown cords.
This for me it's going to match a number of things in your wardrobe and it just has
an overall winter feel.
But, let's say you want to take it to the next level, you want to grab a little bit
more attention, why not bring in a dark burgundy or a red.
This right here when you wear this, you're going to draw a bit more attention to your
legs, but you wear a muted jacket maybe with a muted shirt maybe shoes that look nice,
but aren't going to grab attention and all of a sudden becomes about your pants.
And, again, reds, dark greens for me these symbolize the holiday season.
Next up, how about having a holiday-themed pocket square?
Now, pocket squares are like icebergs, 90% of it is under the surface.
What you don't see is when you pull out a pocket square, the complex patterns and
everything else that's within it.
Now, this one is not holiday-themed, but you could get one that could have the nativity
scene, maybe it's got a nine branched Menorah, maybe it's got little gingerbread men or
Santa Clauses.
I think you guys get the point.
You can have fun with your pocket square, so why not?
Next up, we've got holiday-themed socks so many options out there.
If you're more conservative, you're just getting into this maybe go for a dark green
or dark red, but you want to have fun.
And you know you're going to take those shoes off when you walk into your friend's
house and you want to show off some bright holiday socks, have fun, there were so many
different themes and options out there from snowflakes to, again, Santa Clauses, gingerbread
men, reindeers.
Have fun.
Next up, consider a holiday-themed vest.
And if you're going to go with something novelty like I said snowflakes, maybe gingerbread
men, something that has a big bright repeating patterns, it's a lot better to go with a
vest than a suit especially if you're going to get a custom-made because it's just less
expensive and you'll find more ways to wear it because you can wear it under a classic
conservative suit.
You can actually bring it into the office wear it in the office party a little bit later.
It's something that if you decide to go with a dark red, a dark green, maybe even
a tartan, you're going to find that this is actually, you can even wear it outside
of the holiday season.
So, I think a vest is something a lot of guys don't consider, but you could bring in and
look great this holiday season.
So, I had a few options here.
I was thinking holiday-themed glasses and maybe going for gold, dark red, dark blue,
dark green.
Maybe going for holiday-themed flannels, I love the red with the black, but also the
blue with black, the dark green with black.
For me, that symbolizes the holidays.
But, what I realized is a lot of these is just my association of these items and me
having conditioned myself.
So, I want to hear from you guys.
Down in the comments, what are the men's accessories the items that you wear particular
pieces of clothing that you associate with the holiday season?
I want to hear from you guys.
I love learning from you.
Now, MeUndies, again, guys, go check them out.
I'm linking to them in the description.
I've got all these underwear that they sent me that is the wrong size and it's brand
new, I promise.
I will be sending it out, you just got to go check out their website and let me know
the exact style.
Sad – sad to lose these penguins.
Actually, I like these gingerbread men as well, but the size is not mine.
Again, let me know the exact name of the underwear down in the comments, the size that you need
and I'll be sending those out.
Guys, that's it.
Take care.
I'll see you in the next video.
Bye. [0:09:04] End of Audio
