What about archamedies principle?
If you fill a hot tub/barrel/bucket/pool up to the very tip top and step in, the water is displaced and spills or why if it’s low and you have boots on, the water fill become higher and go over the top and fill your boot up?

The hot dog equation. 1/2 paper towel, rolled around hot dog, soak wet, microwave for 1 minute.
What kind of microwave you using? Any of the ones I've had, a minute would waaayyy overcook a hotdog. 20-25 seconds is plenty.

Other other way around.
Take N-S, apply steady, irrotational, incompressible, and inviscid assumptions to get Bernoulli.

I don’t belong in this thread.

pretty surprised Euler’s formula didn’t make the list. It leads to the conclusion that e^i*pi + 1 = 0, fundamentally relating two transcendental numbers and completely different concepts of mathematics in a very elegant way

Look for i in another equation in this list.

i2 = sqrt( -1 ) = 1 @ 90 degrees = (x = 0, y = 1)

What's really nuts to me is I always wanted to know how did that equation come to pass. Teachers generally just say put X into Y and whatever. I hated it.
I don't know if you get that, but it was always don't give me the formula, I want to see the math. Most people probably don't, I get that. That's why I hated my teachers lol.
So you talking about wanting to know the proof of the equation? When I was taking math in school they never really harped too much on the actual proof, and would rather you do the plug and play type of math. But actually learning the proof and why it is what it is, is way more important. Problem is, I don't think my math teachers really understood it either.

Whew, so I did remember that correctly

Yup.
Hypersonics these days.

I did not know there were so many PhD's here. I was taught 3 4 5 by grandfather building docks and boat houses before my teens. I learned how to prove the 3rd law of thermodynamics at 18. FT's, partial DE's were a part of my job until I moved to operations. I own 4 versions of Perry's and 5 versions of CRC.
But why would an ordinary person care about these equations?

Without looking at anything first, I was able to name 9, 8 of them were on this page.
