If MinutePhysics wanted to make a series of 3 hour long educational videos, I'd totally watch them.

You lost me at
"We're going to start with a rocket"

"It's not rocket sci... wait it is." KSP scientist 2012

[WarrenGarabrandt]

Instructions were unclear. My refrigerator is now broken.

[zwiuhxd]

I would need to exhaust 3, 1 liters of water per second to levitate

[luisgomez]

Anyone else looking at the comment section for someone who did the milk vomit equation?

[galaxynva]

This cant be this hard, i mean, its not rocket science

[HT-rqpi]

With formulas like the ones in this video, i can only truly understand it when im sitting at a desk with a pencil and a piece of paper and attempt to derive it by myself. Its just too difficult to grasp the concepts when someone is verbally explaining it to you. 

[RaimarLunardi]

Instructions unclear, end up in the moon...

[jakez]

Clearly Kerbal Space Program has taught me nothing.

As a physics student, I wish you'd make more videos like these. THIS is what I go through while studying physics and it's a good representative of what's to come in university.

I hope people understand that whenever we physics people try to explain physical phenomena in non-mathy terms, we do it by translation - and because it's a translation, we can never give you the entire picture. Nature is intrinsically mathematical so there's no use in learning physics without doing math.

It is 1:03 AM and I'm learning rocket science... nice

[dibbidydoo]

If this is simplified version of basic rocket science then I hate to see the original.

[justaregulartoaster]

Instructions unclear. Currently stuck in the ceiling fan.
Update: i managed to turn off the fan.
Update2: obtained basic knowledge about vomiting

In 1986 (?) a rocket blew up during launch. Seven died, and millions were saddened. Do you know why? It was cause of a rubber o-ring being too cold. Seven people died off of a ring. A fucking ring was too cold. Rocket science is hard because the margin of error is so small, one tiny mistake can cause stuff like that to happen. That’s why rocket engineers are so smart, they are trained to look for every little detail.;

Why am i not surprised nobody posted howmuch they need to vomit to levitate :P

[isodope]

Your final formula gives the volume of fuel needed to hover for one second.

[chetanphoenix]

The formula is actually volume per second to be expelled to hover.
Little unit calculations

Sqrt(A.M.g/density) which is sqrt (m^2 . kg . m/s^2 ÷ (kg/m^3)). => m^3/s

I just compared this video to an instructional to approaching women. I gotta say this shit is actually easier to understand!

11 yo me trying to become a rocket scientist: _uHM... nUh uH_
