I remember a few years ago I read about a new kind of mind science that was just starting, they had a guest-lecture at my university I think, but I can't remember what they called the new discipline.
It was described as a new science discipline aiming at getting a better understanding for the...
I just think that while we are different from other animals, it might be that we aren't _that_ different, as it seems you have asserted to the contrary. I don't think the experience of being a dog or an ape is necessarily that much different from being a human, on a basic level (of course I...
Try a more systematic approach:
- How many electrons does it take to make up -38\mbox{\mu C} charge? (hint: use the electron charge)
- How many electrons are in 3.0g copper (when neutral)? (29 per copper atom)
You can use substitution.
y=au\Rightarrow \frac{dy}{du}=a\Rightarrow du=\frac{dy}{a}
Therefore,
\int ae^{au}du=\int ae^{y}\frac{1}{a}dy=\int e^{y}dy=e^{y}+C=e^{au}+C
Sorry if this is really basic, I'm no quantum guru yet :tongue:, but could you say that the (classical) velocity is in the direction where \vec J has global max at a given t? Is it possible somehow to calculate \vec v from \vec J?
An elemtary example of energy quantization is in the H atom, where the lowest possible (ground state) energy of the electron is about -13.6 eV (minimum 13.6 eV is needed to free it from the H atom when it's in this state). And as long as the electron is attached to the H atom, it can only have...
First of all, thanks for the help Nenad.
I guess I should've mentioned the text was in Norwegian, and heat transfer coefficient seemed like the most direct translation of the wording in the text. Another thing I think i mis-translated was that it said stationary conditions, not equillibrium...
I'm having a bit of trouble with a Thermal Physics excercise. I was wondering if anyone knew what the definition of the heat transfer coefficient was? I can't find anything about it in my textbook (Thermal Physics, 2nd ed., C.B.P. Finn).
More specifically, the assignment at hand says to find...
A friend of mine recently put my attention to this streaming video advertisement for an entheogenesis conference on Pot-TV: http://pot.tv/archive/shows/pottvshowse-3398.html
In it there is a reference to a prof. Francis Thackeray from South Africa (and a prof. Vandemir[?]; not sure if I made...
