I'm not going to mention any schools; it's quite irrelevant. In any case... twenty years ago, it wasn't as common to go to college. Now that pretty much everybody is doing it, colleges are getting a huge influx of people that act in accordance with the description in my previous post. Maybe it...
I'm not trying to sound too critical, but in my opinion, you need to tone it down a bit and focus on the things that actually matter. Your posts have a very pretentious air to them, and it calls your true motives into question. Are you doing this because you want everybody to think highly of...
Sorry if this question has been asked a million times.
Either way, I'm working my way through Griffiths. It's a fantastic book--he doesn't try to slip anything past the reader. He is completely honest, and he doesn't abuse mathematics the way most authors do (screwing around with the Dirac...
There is a paper by Arthur W Dox and Lester Yoder called "Alkylbenzene Barbituric Acids." This was published in JACS in 1922. I found the answer in the experimental section. Look up the paper and give it a read.
I'm not trying to make you sweat... If you don't respond by tomorrow, I'll just...
Hello everybody!
In about 2 months, I will be taking 4 of the standardized ACS chemistry exams (physical, organic, inorganic, and biochemistry). I bought the official guides for physical chemistry and organic chemistry, and they've been extremely helpful. I blew through the organic chemistry...
Understanding why an integral represents the area under a curve is actually fairly straightforward. Convince yourself that you can estimate the area under a curve as a Riemann Sum:

A 1-dimensional integral is just a limit of these sums. The reason why...
Sorry to tell you, but:
"In mathematics you don't understand things. You just get used to them." - Neumann
You are suffering from something that should really be more common in our universities... Half of the people out there follow equations blindly, while the other half are afraid to admit...
This is how the author did it. I'm not the best at visualizing spherical coordinates, so I employed x-hat and y-hat instead. According to the geometry of the problem, my solution will actually boil down to yours, and the integrals come out the same :)
Thanks for the help!
An open system can exchange matter and energy through its boundary. A closed system can exchange energy but NOT matter through its boundary. An isolated system can exchange neither energy nor matter through its boundary.
Humans are open systems, and not closed systems like you mentioned. We...
Hello everybody! Although this may sound like a homework problem, I can assure you that it isn't. To prove it, I will give you the answer: 40pi.
So.. I'm self-studying some electrodynamics. I'm using the third edition of Griffiths, and I have a quick question. For those who own the book and...
I'm using McQuarrie's "Statistical Mechanics" for a class, and I'm not quite understanding the the derivation of the Boltzmann Distribution. I'm going to go through it, and then ask a few questions along the way.
All right. You start with a canonical ensemble with N, V, and T fixed. Heat can...
