I don't have the necessary learning and experience to understand these sex jokes. We should go back to math/physics jokes, which I can understand.

MATLAB sucks...

How do you graph points onto a sphere so it's evenly spread out? I'm specifically trying to create a hollow shell of discrete points for demonstrating the shell theorem. I tried several things and ended up with a line, a cube, moving points, along with a host of other random results... Thanks in adv...

Re: Mah Learnins

Silly high-schooler, you have the first two years of college to figure that out! But you should probably choose in a vague sense. You said you like math/sci? Are you more interested in the fun and exciting theoretical fields or the dull and boring applied fields? If you like the former, go to a libe...

Re: Majoring in Math

On a related note, are there really no career opportunities for pure mathematicians other than teaching? I mean, I guess you can be a research professor, but no one would hire you for that unless you were extremely qualified (and even then, wouldn't most universities force you to teach?). I mean, I ...

Re: Smooth yet non-differentiable functions

Wouldn't a function with an infinite slope at some point be non-differentiable (example: cube root of x).

Well, I guess that only applies for dy/dx.

I just noticed something. There's more than one definition for "purity."
And yes, mathematicians are the most "pure."

Gravitational Flux?

During AP Physics the past year, I remember the teacher asking a "thought question" that we never got to: is there such a thing as gravitational flux? So after thinking about it, I came up with this: grav. flux = div(grav. field) = 4(pi)Gm, where G=universal grav. constant and m=mass enclo...

I'm in a similar predicament. I'm not the greatest mathematician, but I'm pretty much set on majoring in math.

Re: is anything actually random?

This is somewhat related: Do we have free will?

Re: so maths is useful for what now?

Math isn't meant to be useful--it's meant to be meaningful. That doesn't mean that there aren't any real-life applications that come from it. The most common application that people come up with is probably the use of various methods that one might memorize over the course of one's math education, b...

The ionization has to do with the electron configuration of the atom, and every element has a unique electron configuration.

Silver's most common ion state is +1 which means it lets go of one electron easily. You mentioned copper, which can be +1 or +2. However, +2 is more common because it is more stable. As a rule of thumb, the lower the charge, the more easily it can let go of electrons. Gold is more commonly used howe...
