  1. well, i was going from memory. i didn't think i would have it totally correct. that still doesn't help me get the wavefuntion.
  2. do photons have mass? i always assumed that since they have no rest mass, they have no mass. i wanted to find out so i did a little math. i took [math]E=hf[/math] and [math]E^2=m^2c^4+p^2c^4[/math] and put them togather. i got [math]m=\frac{hf}{{c^2}{(1+c^2)^{\frac{1}{2}}}}[/math]. when i solved, i found that the mass was zero. i took a closer look and saw that that wasn't true, for if i put 0 in for m, the photon would have 0 energy. then i decided to put in a stupidly high value for the frequency and i found it DID have mass. it is just so close to 0 at normal frequencys that you don't need to worry about it. i decided to pick a mass and find the frequency. i chose 1 nanogram. i got 4.07x10^46hz. that brings me to my question. the highest frequencys i know of are terahertz rays. is there an upper limit on photon frequency?
  3. i was trying to find the wavelength, not the scalar potential. i didn't even know what it is. by fuhrerkeebs' description, it sounds like it is just potential energy. i thought the schrodinger equation for a free particle deals with how the wave acts. isn't the schrodinger equation for a free particle [math]i\hbar\frac{\delta}{{\delta}{t}}\psi(r,t)=-\frac{{\hbar}^2}{2m}\Delta\psi(r,t)[/math]?
  4. wow, i have no clue how to do that. is there anyone that would be willing to show how step-by-step?
  5. so it is the potential for the slowly varying field? like gravitational or electric potential energy? can you explain that?
  6. not neccesarily. ever use a computer?
  7. enterprise on DVD may 3.
  8. when did the distance between you and an object become a dimension of said object? any image that you draw is 2d(3 including time)
  9. .
  10. we can't imagine 1d? what about circles, lines, ect.?
  11. thanx
  12. i put this in the quick question thread, but got no response. i hope that i could get help here. i was trying to make an interference pattern for electrons and got stuck. [math]\lambda=\frac{h}{p}=\frac{h}{\sqrt{2m(E-V®)}}[/math] i may have gotten the equation wrong because i typed it from memory, but it will have little consequence for my question. what is scalar potential?([math]V®[/math]) another question: how do I get from [math]\lambda and \omega\to\psi(r,t)[/math]?
  13. hell, guessing what other dimensions are like is like a blind man trying to guess what sight is.
  14. test:[math]\lambda[/math] some sybols use abbreviations. like infinity isnt[math]\infty[/math], it is [math]\infty[/math] or square root, or fration. i just assumed that some of them would be abbreviated
  15. i use new posts and who's online
  16. I just bought a book on gravity by john wheeler and kip thorne, and charles misner. it was published in the seventies. it is called "Gravitation." it's kinda old, is it current?
  17. couldn't it also have zero net energy if all matter is virtual? but then shouldn't there be an equal amount of antimatter?
  18. could someone please post all of the greek letters so no one has to guess at the abbreviation LaTeX uses?

  20. could you explain why? i know at the health club in town, they won't let you wieght lift unless you are at least 13.
  21. god did it http://www.caseforacreator.com/home.php. lol http://www.answersincreation.org/

    neutrons

    it is the strong NUCLEAR force. not just the strong force. there is also a weak NUCLEAR force.
