u/WakeoftheStorm Jul 01 '22

I had a professor for astrophysics who got like this. The only problem is the more excited he got the thicker his accent would be, but everyone was so engaged by his energy we didn't want to interrupt him or ask him to slow down. We didn't want to hurt his feelings by saying we couldn't understand him.

It was a weird combination of great and frustrating

u/sully9088 Jul 01 '22

I've had a teacher like this and I was so engaged in the lessons that I didn't get a chance to prepare my book bag when it was time to leave class. In other classes I'd be sitting on the edge of my seat, bookbag already on my back, staring at the clock waiting to be dismissed. This lady's kind of enthusiasm has me locked in and looking forward to future classes. Those are the teachers you remember years later.

I have only 2 years ago gotten into science videos that explain WHY math is the language of the Universe.

I was terrible at maths in secodary school until we got a real hard-ass teacher in my final year. One day we started learning linear programming and he said "this is used for logistics, think of moving tanks around the battlefield", and I got it. It instantly clicked in my brain as to why I was doing what I was doing since I had context rather than just "min B plus or minus the square root of....the....zzzz"

Sometimes the teacher can only do so much when it comes to more advanced topics. This video reminds me of one of my engineering professors from college. She's Ukrainian and had been a part of the Soviet space program - specifically working vibration mechanics of rockets and she had left to come to America after the USSR's collapse. She was teaching core Engineering Mechanics courses to somebody like me who struggled with advanced math concepts. I felt for her as she was brilliant and passionate about engineering who'd worked on some major projects yet she was teaching some dumb dumbs like me. I really tried but just struggled.

The pressure isn't directly relevant. The density is, as that determines the inertia of the air that needs to move out of the way.

You could have two similar setups where one had a gas with half the molecular mass but twice the pressure of the other, and the result would be the same.

9

u/moeburn Jul 01 '22

The pressure isn't directly relevant. The density is, as that determines the inertia of the air that needs to move out of the way.

Really she just used the wrong word, atmospheric pressure is just the static pressure of the air, that doesn't change or do anything in this scenario. But the dynamic pressure of the newspaper impacting the air shot up to a force of over a hundred pounds per square inch, that's what did it.

So is it the earth’s gravity that “pulls” air down? I was always taught atmospheric pressure of 14.7psi could be understood as a 1-inch by 1-inch vertical column of air that weighs 14.7lbs.

If that’s true (even if over-simplified), does that mean that much air is “sitting” on our heads? If a human stepped on a scale at sea level, and you could delete the column of air directly above, would the weight shown on the scale change??

u/quantinuum Jul 01 '22

Sorry, but that’s not correct.

Assuming ideal gas, pressure is just given by volume, temperature and moles (PV=nRT), so mass is not a factor. You could have two gases, one with half molecular weight of the other, and they’d have the same pressure for the same volume at constant T.

Anyway, I agree the correct explanation has to do with the forces acting on the paper, which is indeed determined by density and drag rather than pressure.

u/eshemuta Jul 01 '22

I was thinking that it’s not the pressure, but drag that is creating the force.

5

u/[deleted] Jul 01 '22 edited 3d ago

[deleted]

13

u/BentGadget Jul 01 '22

But air pressure acts on both sides of the paper, for a net force of zero. Drag is the force that matters.

4

u/Enginerdad Jul 01 '22

Pressure is equal on both sides of the paper when it's holding still, but not once the paper starts moving. In motion the pressure above the paper is higher and the pressure below lower. It takes time for air to flow out of the way of the paper above and to fill in the space behind the paper, and until enough time has passed for those pressures to equalize, there's a differential

5

u/PionCurieux Jul 01 '22 edited Jul 01 '22

Isn't that drag, as /u/eshemuta said? A differential of pressure due to compression of molecules on one side, and depression on the other one, due to the movement of the paper (and enhanced by the fact the intake of air is reduced under the paper, due to the table) ?

Edit: I realised that the reduce air intake is far more important that drag here. If the paper was not on the table, the ruler would not have break!
