How is it that one sixth of the gravity portraying itself in the universe has no known source? And that the collective gravity of all galaxies and stars want to slow down the expansion of the universe, yet it is speeding up?
Oh dear... Please... Planes don't propagate the myth of equal transit times. Flight has little to do with the shape of the wing. In fact you could fly with doors as wings, as long as you get the angle of attack right.
There is something called the coanda effect that deflects the air downwards and then due to newtons third law an equal an opposite force pushes the wing upwards.
Actually it is theoretically impossible to fly if air from the top and the bottom reaches the end at the same time.
Okay ... About the airplane. WRONG. The air that goes over top of the wing DOES NOT HAVE TO REACH THE BACK OF THE WING AT THE SAME TIME AS THE AIR THAT GOES BELOW THE WING, so NO, there is no 'low pressure, high pressure' zone. The air that goes over top of the wing is angled downward by the shape of the wing, so when it reaches the back end of the wing, the air goes down. Quite fast. Now, according to Newton's 3rd law, there is an opposite reaction to this: the plane wing is pushes up.
@anonmusNO1 Actually, you're wrong. its called Bernoulli's principle. It very clearly states that as the velocity of a fluid increases, the pressure decreases. So, in this case the fluid (Air) is moving very quickly over the rounded top making it have a low pressure. the air on the bottom, is moving slower, therefor it has a higher pressure, forcing the plane upward.
@ImAProudMileyFan Bernoulli's principle is true. However, nowhere in the gas laws is there a statement that says that when a gas is separated by an object, creating two streams of fluid (air) do those streams have to take equal times to transverse the object in question (the wing). Since the streams do not have to make the transit in equal times, they don't. The one over the wing moves the same speed as the one under the wing. No speed difference, no Bernoulli principle, no pressure difference.
@ImAProudMileyFan Not very. And that question is inherently flawed, because you give no reason for making that assumption. Here is a very good article I found -- I am not wrong, and neither are you ... exactly. If you are a true nerdfighter, you will read the article. If not, you are a straveling, an elf-skin, a dried neat's tongue, and a stock-fish, thou whoreson, senseless villian!
(Go to straight dope (one word) dot com and enter 'airplanes' in the search bar, it is the ninth article down)
what made me pee and question is at 1:09 Henry asks how the internet work and Hank say well your brother and i. and Henry doesnt have a brother but Hank has a brother. I had to watch it 5 times before i was certain of what he said loooool :-)
Dang i thought this would be educational which is kinda was except for the KNOCKED UP question. thanks now i gotta distract my 7 year old from asking ;)
I can't help but think the video bit of the Obi-Wan Earth is counter intuitive. I mean, when you say 'now we are not in the sun's light' you DO know that the sun is on Obi-Wan's face... right?
This is probably my favorite vlogbrothers video of all time! This and the "letter to the aliens" is the reason I subscribed. Thank you both for being awesome.
When Henry watches this, he's going to be confused at the bit where you explain sunlight, because when you said, "Now, we are in the dark," the face of Obi Wan was in the actual sunlight.
Okay depending on what age henrey would be while seeing this but as hank portrays him i'd guess 5-8 and at that age after the scientific questions his responce would be "Whaaaaat?"
@dingo596 well...if you exclude the question of "what is charge?" that's fairly simple to explain...ask wiki, if you don't get it still then tell me and i shall explain it to you the best i can.
It's kind of cool how Nerdfighteria has two people to rally behind; Hank for the Science nerds, and John for the Literature nerds. It makes for more specialized discussions and overall better discourse.
Babies come from zygotes which, if you are patient enough and people in your local community aren't religious zealots forcing their will on schools, you will learn about in the future. Knocked up is a euphemism for the formation of a zygote. BOOM, taught better than Hank
@andtheducksaysmoo because when Wilbur was playing with the plane he switch the controls to default. That got Orville very mad, so he switch them back to inverted, and made that the default settings... The real question is why is 007 Goldeneye inverted?
Help? My tribe is trying to gain Federal Recognition and I would appreciate if you could go onto the website* and sign the petition It ends DECEMBER 1ST !

I said the, "What does getting knocked up mean?" part to my friend in a cute voice,the in a normal voice, "Uhhhhh.... It's... The opposite of getting knocked down. Question time over!" Cute voice, "But that doesn't-" Normal, yet angrier, voice, "QUESTION TIME OVER!!!!!!"
She loved it. She didn't quite get it until I explained it because she doesn't watch vlogbrothers' videos though.
While the difference in the upper and lower curvature of an airplane's wings does does provide some lift, it is nowhere near enough to actually keep an airplane flying. In fact, it is the downward deflection of the airstream as it travels across the wing that provides lift; this is why planes are capable of flying upside down.
I think parts of children come from there uncle and even their half brothers dad even when they have the same mom. I'm an artist and my parents arn't and my uncle is and my half brothers dad is a nerdfighter and my parents think your a bad influence. So there you go those jeans are in their somewhere.
Great vid, dftba, but in point of fact, the high pressure does not in fact PUSH the plane up, but the low pressure PULLS the plane up. Just thought you oughta know.
@SuTVlogs - Not to be a jerk, but 'In point of fact,' the high pressure does indeed PUSH the plane up.
The only currently recognized "Pulling" forces in the universe are gravitation, magnetic dissimilarity, and electrical dissimilarity.
All pressure differences are measured in the net force given off by all atomic collisions between a fluid (in this case air) and a solid (the plane's wing).
These molecular collisions are in fact tiny electrical similarity based repulsive forces, meaning a push.
You probably could have just used the Sun to represent the Sun seeing as one side of Obi Wan Kenobi's head was actually in daylight while the other was dark.
I really really hope my children will ask me what a Horcrux is. Well, any Harry Potter question will do, but I hope they will ask me. I"ll be so proud of them.
Actually, airplanes don't work like that! The wings are actually curved on both sides; the air follows the curve, and when the curve ends, the air continues at the same angle - which is a downwards angle. Since the air is forced down, the airplane goes up!
After all, there isn't any reason why the air on top of the wing needs to go faster - it doesn't need to maintain its position relative to the air below. That's what makes fluids fluid!
I loved that you specified the male and female must be from the same species. Ten points from me - learning the definitions of species and population terms for Biology D:
Hey. I love the videos but there was one answer that wasnt entirely correct. Actually, the sky is blue because when light hits dusts and/or gases in the atmosphere it scatters in a prossess called, go figure, scattering. Blue light is scttered more than other light colors. You were mostly right though, i realize. I just learned about this in school and wantef to sound smart. :) DFTBA
The airfoil explanation is incorrect. The lift that a plane experiences is not due to Bernoulli's Principle as stated, but simply the force generated by pushing the air down. And Newton's 3rd makes it very clear what happens when you push things down -- you get pushed up!
@dolphin64575 newborn babys often have dark hair and light blue eyes.. it change after.... my hair was almoast all white at age of 6 but black as age of 1 day :D

I would love to be Henry Green. One day you get to watch all these videos that your dad and uncle made.

Hey. I love the videos but there was one answer that wasnt entirely correct. Actually, the sky is blue because when light hits dusts and/or gases in the atmosphere it scatters in a prossess called, go figure, scattering. Blue light is scttered more than other light colors. You were mostly right though, i realize. I just learned about this in school and wantef to sound smart. :) DFTBA

"What is a horcrux?"
"Young man, where did you hear that word?"

"What's a--what's a horcrux?"

I love how Hank answered Henry's question about where babies come from, but considered asking about a Horcrux totally unacceptable.

The airfoil explanation is incorrect. The lift that a plane experiences is not due to Bernoulli's Principle as stated, but simply the force generated by pushing the air down. And Newton's 3rd makes it very clear what happens when you push things down -- you get pushed up!

"Well Henry, your BROTHER and I make videos and upload them onto a site called Youtube..."
I was unaware that Henry had a brother and you make videos with him :)

The sun is not staying in one position... Its orbiting another larger sun in the milky way. And that larger sun is orbiting another larger sun (or maybe a black hole)
