  1. Quite caffeine and swith to coca leaves, doesn't last as long, is less jittery..

     

    As long as he's not worried about prison, that'd be a fine suggestion. Coca leaves (yes, the leaves) are Schedule II over here in the U.S...

  2. i don't really see a problem... why not let the kids decide for themselves? if creationism is so obviously untrue, then what do you all have to worry about? i think kids are logical enough to figure out which is right and which is wrong.

     

    It's not a problem of letting the kids decide what to believe, or anything of that sort. The problem is in the fact that ID is not science, and shouldn't be taught in a science classroom. I have no problem with the school systems teaching kids ID in non-science classrooms, but not in a science class.

  3. That would require atheists and agnostics to be as generous and charitable as Christian laypersons. Good luck on that one.

     

    What do atheism and agnosticism have to do with evolution? Yeah, and that whole generous and charitable Christian layperson thing doesn't go too well with the whole uber conservative Republican thing that Christians tend to be into.

  4. First of all, the eigenfunction is a problem for me. The books I have do not describe the function whatsoever(!), does anyone understand it?

     

    When you're talking about Schroedinger's equation, the wave function is the eigenfunction of the equation Hw=Ew, where w is the wave function, H is the hamiltonian, and E are the energy levels. H is the operator, the set of E's are the eigenvalues, and w is the eigenfunction.

     

    Secondly, is Schrodigner's equation only for the electron or for any particle?

     

    Nope, there are a bunch...Dirac's equation describes relativistic spin-1/2 particles (such as electrons).

  5. I've been thinking about this for a while and I just wanted somebody to show me where my proof becomes faulty. This was my attempt to find an asymptotic formula for Mertens' function (the sum of the Mobius function). Oh, and if you aren't clear of my reasoning behind something, just ask...and in case it isn't obvious, I used pn to denote the nth prime number. Sorry about the cheap scan...I don't know how to use Latex...

  6. I don't really know what you want to understand better, but I'll give it a shot:

     

    Think of a tangent space as the set of all vectors that are tangents to some point on an n-manifold. Therefore, the tangent space is an (n-1)-dimensional surface. Since the tangent space is an (n-1)-dimensional surface, the product of Rn and the tangent space of some point on a surface in Rm is an n(m-1)-dimensional space. I don't really know if that's what you want to know, but...

  7. If f(x)=O(g(x)) that just means that for large enough x and some constant c, |f(x)|<=c*g(x). You can use this to give bounds on certain limits, like f(x), if f(x)=g(x)+O(h(x)), because we know that lim x->infinity g(x)-h(x) <= lim x->infinity f(x) <= lim x->infinity g(x)+h(x). I don't really know what you mean by "how the big O's cancel," so I can't help you out there.

  8. I have heard calc is the hardest and I heard the economics tests are monsters.

     

    Eh, I actually consider the Calc BC exam to be the easiest one I've taken thus far...I've found the history ones to be the hardest...

  9. I can't even see the graph of x^x from -something to 0

     

    That's because in the negative numbers alot of the values of the function are complex. Anyways, I don't know if you can find the integral exactly or not, but you can certainly find bounds on the integral.

  10. All of the laws of special relativity are special cases of general relativity (hence the word "special"), and special relativity has been verified to great accuracy. It explains gravitational redshift, light bending around the sun, and the previously unexplained motion of mercury. This should be sufficient proof for you, unless you're like those creationist nutcases and you like to toss out evidence from the real world because it doesn't fit your warped perception of reality.

  11. what is the velocity of B? it says its moving towards A but doesn't give an actual velocity which is required for the question. maybe i missed it cos the image refuses to resize to my screen

     

    Yeah, now that you mention it the velocity of car B isn't mentioned. I didn't notice that they didn't mention it, however, because of the screen.
