Solution of time independent Shroedinger equation with energy eugenvalue E holds oscillating factor of e^{iE/ \hbar \ t} in time. That...

Time and fuel problems aside - great discussion! Gives me goose bumps just to see us starting to think seriously about interstellar...

Perhaps it would be clearer to write: $$\sin x=a,\quad |a|\le 1\Longrightarrow$$ $$x=\arcsin a+2\pi n$$ and $$x=\pi-\arcsin a+2\pi...

It was a solar eclipse yesterday in Europe. Here in Sweden it was partial (ca 80%, if I remember correctly). I learned about it just...

What goes up (in time t) must come down (also in time t)! $$t_1=t_2 \approx 0.6s$$

I had asked at @A.T. : ``Is it also true that for a ball thrown vertically up and which rises to a maximum height ##h##, the time to...

We tend to take books for granted but it's a huge achievement to have actually written one. Congratulations on becoming a published author.

Mind blowing!

$$H=\frac{g}{2}\left(\frac{t_{0}}{2}+\frac{h}{gt_{0}}\right)^{2}$$ I just needed to see your formula.

Google Gemini. Will post all its workings generated after some "coaching" from me. I referred it to following desmos graph...

same thing I think. Just need to coach your AI to tidy up maybe.

Thank you. I will plug that in immediately. As Gemma 4 is based upon Gemini, it would probably fail as well. Not sure if it failed or...

Excellent diagram. Can solve by finding the area under the blue curve between it's x-intercept and point C.
