Whatever's not already on first. Who do you think is first?

Oh, that definitely clears things up. I was actually looking for good comparable examples like these. Thank you for the quick replies! I was really stuck on this.

I was reading about how Heisenberg found out that it is "impossible to determine simultaneously with unlimited precision the position and momentum of a particle" (Serway/Moss/Moyer, 174) \Delta p\Delta x \geqh/2 (where h is plank's constant over 2pi.) My question is why is this true? I...

I was reading about how Heisenberg found out that it is "impossible to determine simultaneously with unlimited precision the position and momentum of a particle" (Serway/Moss/Moyer, 174)My question is why is this true? I read that it had something to do with the large wavenumbers \Deltak, but...

Yes that is what I meant to type, my mistake. I didn't even think of separating the numerator of the equation. :blushing: But I see exactly what you mean. Thank you so much for the help and the quick reply!

Homework Statement I'm supposed to find the inverse Laplace transformation of the following equation Homework Equations G(s) = s+1/s2+25 The Attempt at a Solution I was thinking of using one of the shifting theorems because I know that L-1 {1/s2+25} is just sin(5t) but I don't know how to...

Thanks so much! This helps a lot. I'll definitely be looking at all of your suggestions. The book I'm using now is Modern Physics 3rd edition by Serway, Moses and Moyer. I did want something aimed a little more specifically at quantum physics though Thank you again for your suggestion!

I wasn't really sure if here was where I should be posting such a question, but all the same; I'm currently taking a Modern Physics course and find myself struggling immensely with some of the problems and derivations, particularly when it comes to Schrödinger's equations. I was wondering...

No, its discovery dates back to the late 6th century when an unfortunate rider fell asleep in the saddle during a jousting tournament. Is there a sport more noble then jousting?

I was thinking I could just double the integral from 0 to \infty but because there was an x/x_0 in front and I would have to integrate by parts, I reasoned against it. I wouldn't know how else to simplify it.

Thanks for the fix. I was struggling with it :P

This is a physics problem, but I only need help with the calculus portion of it. I was having trouble figuring out how to split the integral to properly integrate. Homework Statement Homework Equations \int\stackrel{\infty}{-\infty}(x/x_0)e-2|x|/x_0dx where x_o is a constant...

Little known fact: dolphins are the underlings of crows. They're the creatures we should really be concerned about. Who watches the crows?

Because their eyes are filled with dirt. What is filthier than dirt?

None. The power cord of the one taken away dragged the rest of them off the table top and onto the floor. What's red?
