Hmmm.. mass times potato divided by escape velocity equals abracadabra you say? Yes, intadesting...

well i'm not a physicist nor a physics theacher, but we use the ' x ' to multiply in the primary schools, and then just a dot or nothing at all.

Dot is technically vector notation which would be fine for most of these values but is incorrect for pure scalars..

in my country it's the opposite: nothing for pure scalars, dot for scalar multiplication between vectors and 'x' for vectorial multiplication

Does anyone know how to decipher that alien language?

i learned a lot of this during physics A-level. i wish i choose physics at uni instead of engineering now. so much more intresting and fun

FD.


FD is the part I don't understand.

F is obviously force, given the values on the right. I suspect the 'D' denotes 'downward'. So, downward force?

I'm not 100% certain, but:
first one:( mass*escape speed^2) = Gravitational potential energy. its a kinetic energy equation. dealing with velocity needed to escape the gravitational pull.
2-4(?)) all deal with gravity, radius, escape speed, and launch angle
5(?)) ???
6)Nm=velocity / light speed (chemistry equation)
7) light speed = root(k*R*Temperature) k and R are chemistry constants.
8?)force = work x escape speed + (P(earth) - P(applied)) x A(earth)
9(?)) momentum = mass x Velocity
last one: force = derivative of momentum

Most of this is from 1st/2nd level college level physics and chemistry classes.

huh... all these pre-req. engineering courses are finally paying off.

I'm pretty sure 5 is a definition of e, a mathematical constant similar to pi.

those are the calculations involved in launching an object out of the solar system. The cup is from members of the Voyager program.

All I know is the first one is the gravitational constant equation, and the second to last one is momentum. weh i am uneducated

well i am not on this level, and im not sure i want to be, i mean i guess knowing any of this would be nice, mark of pride, but what does a average crazy person like me need any knowledge of rocket science?

A lot of these are Electrical, and i also saw Bernoulli's equation. A lot of dorky nonsense honestly.

I don't even have to look at the comments to know what they consist of. I'm not much of a math person, but I am pretty good at predicting what people do.

TL;DR: You're all a bunch of nerds.

There isn't anything that complicated here. There are even some really simple equations like p=mv and c=sq(krt). There is like maybe some very simple calc/trig in there at most with the sin2 and stuff.
