It's a shame they didn't talk about the run down a mountain theory.
Jack Derbyshire Why is it a shame? It's nowhere near being within the realm of possibility.
no, but it would've been funny don't you think?
No. lol
Maccaroney oh, okay.
+Jack Derbyshire You could do it, but the conditions would have to be perfect for it have to happen.
I love that at pretty much every turn it seems Gavin has been right from the start, and the others just completely ignore it, like they didn't spend entire podcasts calling him an idiot for it.
That thing that Gavin said about your phone being the same size was a classic example of Gavin being right, but not knowing how to explain it.
What he meant was, no matter how far away or how close you are to a mirror, you (or an object) are always the same size.
You can see this if you trace your phone with a dry erase marker on a mirror, then step back 2 feet and trace the reflection. :-)
I remember seeing a video about that. It was so trippy
+japanime555 do you have the link?
+Brandon Cantoran I couldn't find the link but you can look it up or you can test it yourself. Just get an object and stand like 10 feet or so from the mirror and mark with tape or something the outline of the reflection then move the object like 10 inches from the mirror, it should be the same size and fit in the outline
japanime555 trace the reflection? To be honest, I don't even understand the concept
+japanime555 since it doesn't show up, look up physic stack exchange on google and search for objects same size in mirror
its a run down a mountain theory that they didnt talk about a shame
i got a question, i got a question: What are you on about
+NJLamp Films Xd
What does that mean? - Burnie.... XD
"Go ahead."
The more I watch of Gavin the more I realise he's actually pretty intelligent... he just has no idea how to use words.
Well, he is a part of AH, they do words good
i just got crazy deja vu reading your comment for the second after like 3 years. that was so weird
@@MrBigNicholas The best part is i just ended up here, not because of your reply, but because of the Run Down a mountain theory and trying to remember if she explained it.
I also forgot i left that comment, and got deja vu lol
No pop smoke but it’s because he’s a….Foreigner
gus' expression after she says "yes" at 19:44 is amazing
Sally: There are no dumb questions
RT and the Community: You would be surprised
I like watching how Sally Le Page gets more and more into talking to them and starts to banter a bit. Proves a point to how great at talking they are- even to people that they don't know!
Thank god someone finally set Burnie straight with the senses argument.
I dunno, I still think they've both got a point.
It’s more defined than color or numbers though, because there exists a definite number of senses, we just can’t name them all.
There is not a definite number of colors in the same way there is not a definite amount of numbers between 0 and 1 - you can continue to increase the margin to make the number/color gradient infinitesimally small, but you cannot do that for the number of human senses, at least not infinitely.
@@thewovenmantis6813 Well there isn’t really a defined amount of senses. The question is how you define them. Like how she said you can technically call hearing an extension of feel because of the way your ear works. It’s a problem with classification, not quantity.
@@rddsknk89 True that.
I love how broken Barb looks during the lightyear pole theory.
Her hair is fantastic
her everything is fantastic
FuzzyBuns09 are we talking about barbara?
gus is pretty fucking amazing yes
U HAVIN' A LAUGH?? U HAVIN' A GODDAMN LAUGH!?!
Of what? You???
I love that she gives an explanation (usually a good one, though whether its correct or not I don't know) and then Gavin immediately chimes in with something that just kind of...overwrites what she says.
It's a shame they didn't talk about the theory of running down mountains.
this video really shows how much of an accent Gavin lost since moving to austin
not really, British accents vary a ton. if I met Gavin and person, it would be very obvious that we were two people from total different parts of the country.
It's a shame they didn't talk about Gavin's run-down-a-mountain theory
Mozata Pumishmumi Impossible.
Cutting someones brain stem and having them survive is impossible.
#1 essentially boils down to: if you need to take off really quickly during a nuclear armageddon, aim towards the closest blast.
It's a shame they didn't mention the running down a mountain theroy.
Anyone else notice that Gavin has probably watched alot of Vsauce?
God I need more conversations of Burnie fighting large animals.
He literally said ‘I’m kinda worried about a grizzly bear’
Bruh. A GRIZZLY BEAR. A human would get one shotted. One swipe and you wish that would’ve killed you.
Wyoming here; can confirm. I run into grizzlies once or twice a year at work, but the main reason why that's gone OK so far is *I DO NOT PISS THEM OFF.*
Barbara is just so lost..
Kevin the alien : What is she on?
@@tribot9688 booze and the dumb blonde gene
Bless this wonderful and patient angel of science who was so willing to deal with these idiots we all adore so much.
the reason why celsius is more useful is that 0degreesC is the point at which water can exist in its three states (solid, liquid and gas) depending on the conditions, giving you a fixed reference to tell temperature from
Barbara sitting there quietly smiling while the gentlemen speak about science.
they need an astrophysicist next
BILL BILL BILL BILL
YES! So they can ask him about biology questions.
Ik everyone’s gonna say bill nye or Neil, but ummmmmmmm. Brian may? Lead guitarist for queen? He’s got a degree in Astrophysics I think, and I don’t know if you can have more big dick energy than astrophysicist and rock legend
They should get bill nye to answer their physics questions
dartzu Or Black Science Guy
+dartzu Bill would probably yell at them, Neil Tyson would be better, he seems more grounded.
+Ryva Alpharus Renamon "Black Science Guy" XD LOL
+xXSpiderVenomXx you mean Neil Degrasse Tyson?
Bill Nye is MA DOOD!
"when its hot... whhy dont we all get naked?"
*cuts to black*
She has nice legs as well
I've been doing that alone for 5 years now.
I wish she would stay on the podcast, She would make it so much better lmao
The sense of “which way you’re facing” is the internal compass.
people talking about how she seems to be into gavin but i feel like she's into barb
More likely she got ordained.
It's a shame they didn't bring up the run-down-a-mountain-theory
Sally is AWESOME! I love seeing her on the RTP.
Listening to her explain physics is like nails to a chalkboard
Question:
If I take a pre-cooled 5 gallon plastic bucket and fill it with iced water (33' F) does the entire 5 gallons of water instantaneously turn to ice when it reaches 32' F ? OR does the water require some time at 32' F or less for the water to turn to ice? I was always under the belief that the water instantaneously turns to a solid block of ice within seconds after reaching 32" F or less? Before a hurricane, people NEED ice. I thought this could be an easy way to produce large quantities of giant cylinders of ice in short time. Please respond.
Gavin has a glint in his eyes whenever the girl talks to him
Burnie even if you had a gun in a room with a Tiger, It would still eat yo ass.
Tigers don't play no shit.
Eyes and throat.. I got it
The Truth His argument is so annoying. All the animals he talks about are not only much bigger than him, but have evolved into some of the most effective predators in the world, they literally evolved to be so good at fighting and ripping other animals to bits that even handguns and rifles wouldn't guarantee you winning if they're close enough.
His argument is on the intellectual level of a 5 year old:
"I could do that"
"oh yeah? Prove it."
"Nuh-uh, but I could."
Tigers can carry... yes carry, not drag, a fully grown cow in its mouth... If you've ever seen a cow before you'll know that a tiger isn't something to fuck with if it can do that.. It can also drag something 550kg (1200+ lbs) 10 feet up into a tree... Just think about that
The Truth Exactly! I cannot believe that Burnie thinks that he could fend off a tiger even for a second! Even if he somehow managed to hit its eyes, that means he's close enough for it to literally bite his arm off or worse.
Two shots with just about any handgun, one in each eye, and it is dead.
Burnies problem is he doesnt actually have any perception of the power and speed of a Tiger, hes never fought so he doesnt understand that theres a keen difference between intellectual and perceptive limits and physical limits. He can outsmart a Tiger but its futile because said Tiger has enough power to break both his arms and the Table or chair he uses from said room. Now even if he manages to avoid a strike and go for the Tigers eyes or throat as he says. He wont be able to move quick enough to land a counter before recieving the next strike, in other words, in close quarters with a Tiger, he would not be able to block strikes, nor avoid them imdefinately, nor counter them, so any plan involving that would be futile, so even with a gun, his best bet is either to get out, or wound the animal enough that it doesnt want to eat him.
Or just use his teeth to rip out the tigers throat then drag it away to feed on it later.
It's a shame they didn't talk about Darude-Sandstorm.
This was so satisfying to watch. But I can't believe Burnie has such a high opinion of himself that he thinks he could take on a Tiger and live. This is the same guy who said, drop him in the middle of the English Channel alone, he'll make it to the other side. Yeah, right.
So serious so wow
Alex O'Connor He punched out an angry horse.
Just saying.
Anthony Serocco but it was just chewing on his wife's (ex wife) finger, its not like it was trying to rip her finger off or stampeding around.
Alex O'Connor ive had a friend that swam the channel so Burnie could do it i suppose
Alex O'Connor the channel swim is very possible
would love to have Sally on every so often lol just to correct them lol
Picturing gavin trying to give a kitten a bath is hilarious.
I love how it opens with the airplane on a treadmill theory which has been sorted out already. It can take off because the propellers or jets cause the thrust, not the wheels.
When he asks how many senses there are Barbara says "I don't want to be a part of this discussion" after not speaking for 10 minutes.
Very nicely done video!
I'm a pilot so when she said you get thrust from air going over the wings that made me cry because that generates lift. The wing is an airfoil that is created from Bernoulli's principle that if molecule A (goes over the top) and molecule B (goes under the bottom) are separated at the leading edge of the wing and the distance over the top of the wing is longer than the distance underneath then molecule A will be moving at higher speed with less pressure than molecule B creating lift. Thrust is generated from the prop throwing air behind the plane pushing it forward.
Holy crap this was great.
I understand Burnie's thing about the tiger. I think the same thing about my classmates. :)
Look at Barbara during the push question 😂
WE WANT Moreeeeee!!!!!!!
I just want to know what aircraft they think is driven primarily by it's wheels on take off? Also Barb's facial expressions throughout this are great
17:32 the moment barb knew she was out shined by miles and got intimidated 🤣🤣🤣
quick guide to Fahrenheit: think of temperature in Fahrenheit as the percentage of how hot something is. 32% hot (freezing point) isn't very hot at all while 212% hot (boiling point) is beyond reasonable heat.
To add to the conversation about starving in a desert sandwich question, it is known that the brain does have the power to self-destruct the body. The brain can essentially send a message to the rest of the body to self-terminate, usually in an instance where it believes it is going to die anyway. Thus, I would have to guess that if the brain does send such a message if it believes it is about to die of starvation or something else, it may be prevented of self destructing if new information comes in that may prevent death.
Of course, you'd run out of energy and material to stay alive after a while so you can't survive on hope alone.
Also, Burnie you are so full of shit if you think you could fight a tiger with your bare hands. Human intelligence means we can make and use guns, it doesn't stop tigers from being bigger, faster, and stronger than us; and people with guns still get killed by tigers. If that tiger wanted to kill you, it would pounce on you and tear you apart.
I think Burnie is just ignorant of the strength a tiger possesses. He agrees that he couldn't take on a bear but at the end of the day, the outcome is the same. A tiger is so much quicker, before you even have time to react, it would pounce, go for your throat, tear you limb from limb at the blink of an eye. If by some miracle you were able to, I don't know, jump on the animals back? It would flail around wildly with strength much greater than your own.
However, a part of me still doesn't want to say the possibility is absolute zero, which is what I think Burnie really means when he says that. The possibility of him surviving, not killing, a tiger, is not 0 percent absolutely, but it's really, really, really, really, really, really, really low.
Maybe the tiger's sick? Old, tired. You might be able to sneak up on it while it slept, there's an advantage there. You could create some kind of weapon on your person, like taking your belt and using it to try and strangle the animal, the chances of surviving are still severely low, but it isn't 0 percent.
+Bradley Coates (EvilKIRBY23) Nah, Burnies problem is he overvales intelligence. He thinks that "Oh, I'm smarter then an animal, I know where it's weakspot would be/the best point to hit it", which
1)He has 0 idea if he is smarter then an animal or not, and
2) While that might work for smaller animals, if you face a massive tiger, he only needs to scratch you once to hurt you enough to the point where you're fucked no matter what you do next.
Yayyy British education system. providing Gavin isn't as dumb as AH think he is.
He is just not very articulate.
Christopher Baker I feel like he’s smart, but he’s also an idiot
'A scientist talks about science' - new TSHIRT!
Not a single comment about the lady? Wow TH-cam, I'm really impressed.
***** It's a shame.
+AKindChap Four months later...
Hilarious comment. Well done.
Oh my god Gavin!
"I have a question."
"Go ahead."
"What are you on about?"
Fahrenheit was in fact developed with 100 degrees being the temperature of the human body, so it really is better for measuring temperature relative to the human feeling of how "hot" the world around you is.
Absolutely massive fan angled in the right way is called a wind tunnel btw.
Sally's "wot," was adorable.
Interstellar:(I haven't seen the movie in a super long time so I won't say names) the Main Character is losing oxygen in his suit due to a fight with Matt Damon's character. As the Main Character is dying Matt Damon's character says that the thought of his children will make him live longer. So I'm sure seeing a sandwich when your starving to death will make you live longer
well saying that about his kids, was a phrase not literally, seeing your kids wouldn't do anything.
if you breakdown,
if i saw somebody i love, i'd live longer even though my death is going to happen, sadly thats not the case, as emotions don't have an impact on well health etc
its a fucking movie idiot
Grant Golke yes we know. well done dude.
Ok so people didn't get that it was a joke. Sorry for offending you guys
27:00 was this in a podcast? Link?
I love her.
Barbara trying to act like she's not an idiot too. Lmao
Can confirm that the difference of one degree is huge to some people. My family used to have a game where we’d try to change the thermostat to mess with my dad and he’d always be able to tell, even if it was by one degree. 😂 it was like his superpower.
Barbara's face when Burnie is talking long poles and pushing and taking pictures of it.
At 14:00 when they're talking about things that might happen in a new environment, i wished they'd talk about when america launched nuclear warhead into the atmosphere just to see what would happen to the magnetic field
10:05 Barbara is lost XD
I love how they try to persuade the scientist that she's wrong in some of the questions.
Yeah, their arrogant and want to be right no matter what.
Can we put Burnie in a suit of armor and lock him in a room with a tiger or panther?
Yes but without the suit of armour
with the farenheit thing, it also depends on where you live, if you live closer to the Arctic you'd be able to survive lower temperatures but wouldn't do as well in higher temperatures, if you lived by the equator you would do good in higher temperatures but not as good in lower. it's all about conditioning like in brave new world
The only dumb questions are those that go unasked.
She was so close to being totally correct about information travelling faster than light, and then she simplified pressure waves to mach 1.
Airplanes don't propel themselves using torque on their wheels from a drive shaft.
Their wheels are largely in a neutral state and they move by pushing air.
So the ultimate question of what happens when you put a plane on a treadmill depends on how big the plane and tread mill is, what speed it's moving, the ambient wind speed, the orientation on the plane, and ultimately the friction of the wheel assembly compared to the friction on the ground - does the motion of the treadmill move the wheels in the wheel assembly.
If it doesn't then the plane will move along on the treadmill until differences in air over the wings probably cause the plane to crash
If it's lined up with the treadmill and the frictions are all tuned correctly, a plane will just basically roll off the treadmill. If you apply propelled force the plane more or less ignores the treadmill and takes off like normal
In the real world there would probably be some kind of material failure at some point - we don't launch planes off treadmills because it's a stupid thing to do. But theoretically it basically works.
"i can't pronounce anything. FOSTER."
"Fothter"
omg hi Jensen :D
why didn't they ask about the running down the mountain theory
Burnie has no idea how much faster and stronger tigers are than human beings. Not just running, they move a lot faster. With a spear you might have a chance of surviving but it would fuck you up.
If a grown up tiger is hungry enough it wouldn't just "fuck you up" it would kill you in minutes. Burnie doesn't understand how weak and not capable of hurting anything us humans are. We don't have claws or teeth, which is what animals use to kill each other. Burnie wouldn't stand a chance, even in an open space or with a spear. I really hate how he doesn't see it already :P
+Nor1ar
That's why we made tools. A man with a submachine vs a lion. Which do you think would win?
the argument didnt include guns or tools
CaptainVarg
What about armor? Or exoskeletons?
exoskeletons barely exist and armor would do nothing against a tiger. People seem to vastly underestimate how fast, smart and strong tigers are they are an apex predator for a reason
I SAID NO WATER ANIMALS! "How about a Hippo on land?" .....Nah that's a water animal xD So funny!
I like the Celsius scale because 0 is the freezing point of water and 100 is the boiling point and water is the most important ingredient to life.
I find her incredibly attractive.
I do also
The Placebo effect is proof that humans are psychic to some extent. We can literally change reality by thinking.
A plane can still take off on a treadmill because what moves it forward is the thrust from the engines. The wheels rolling on the ground have no effect on forward movement. If the treadmill was travelling at 20,000 mph the wheels would burn up before anything.
Its a shame that its a shame that its a shame that its a shame that its a shame...
TheEasyNinja ...shame that
So around the 20 min. Mark how could we see into the past; how would the old light bounce back and show us what had happened 2 years ago? I understand how it would be two years but I don’t get how we would be able to see into the past
(So then we would see a past image of ourselves because the light takes our image and takes a year to send it tot he mirror and then it takes that image and send it back in another year so in 2 years we will see the past image of ourselves? If this is the case would it be possible to do this mirror trick with moving people/ video so that in 2 years we could see a moving picture of what we had done 2 years ago???)
But if you flip a coin three times...
I love the sciencey parts of the podcasts. They're the most fun........Mostly because of Burnie and Gus arguing. p:
Gavin's accent has changed drastically since the first occurrence of this story
Anyone Got a Link to that Bear video
The need her to talk about running down a mountain
Most children are taught that the human body has five senses: sight, hearing, touch, taste, and smell. But many neurologists identify nine or more senses, and some list as many as 21.
A plane can take off on any flat surface, moving or otherwise. The engines are not pushing on the ground, they are pushing on the surrounding air. As long as the plane can move forward through the air around it, it will take off.
it's a shame they diddint talk about the run down the mountain theory
Burnie: "Yo peep my nest"
I felt like my brain was going to fucking explode when they were going on abt the mirrors
So they got a biologist to answer physics questions? It's like bring a zoologist to answer questions about quantum theory.
The problem with fighting a tiger or a lion is that they've literally evolved for millions of years to be able to kill things and eat them, whereas we've just evolved intellectually, not combatually. The tiger would kill you in seconds just due to sheer strength alone.
I still insist that the plane would take off, because as the turbines would spin it would induce a slight air current underneath the wings which I believe would generate enough lift to ever so slightly reduce the downwards force on the wheels, which would in turn reduce the frictional force acting opposite to the thrust of the turbines, causing a net positive force in the "forward" direction and the plane would speed up, eventually moving quickly enough to take off. Further, as the plane's engines ran, it would burn fuel and become lighter also reducing the downward force on the wheels, and the rest would follow as described prior.
Alan Gresov the plane would take off but for none of the reasons you described. There seems to be a misconception here. A lot of people seem to be having it and I just figured it out myself and wanted to explain.
The wheels are not powered on a plane. The force that pushes the plane forward is the engine. Unlike a car's engine, it is not in anyway connected to the wheels. A car's engine delibritely turns the wheels and makes the mass of the car move. Here the engine pushes the mass of the plane forward and the wheels are forced to turn underneath (again comparing them to a car, almost like they are always in neutral). This means that the ground is in a way irrelevant to the plane moving. Adding a treadmill like conveyor won't change this.
The engine does not make the wheels turn and then in turn make the plane move, however it makes the plane move and in turn the wheels spin. The wheels act as an agent to reduce friction between the mass of the plane and the ground. The plane will always move forward no matter how the treadmill is constructed.
actually adding a treadmill does make a difference in practice, because the wheels aren't an ideal machine, if you have the treadmill moving fast enough, eventually the plane would no longer be able to accelerate forward because the frictional forces between the wheels and the connecting parts would cancel out the forward force vectors of the engines.
if anyone wants a perfect example of what's wrong with the internet just look at the top two comments...they're both exactly the same, and were both posted on the same year, yet one has more thumbs up than the other.
I should never be a science teacher because these would be on a pop quiz..
