    Theoretical and actual limits to electromagnetic frequencies?

    i'd like to know two things a) is there a theoretical upper and/or lower bound to electromagnetic frequencies in the universe? I'm thinking for an upper limit, 1/planck time? for a lower limit, i have no idea-- does Heisenberg uncertainty calculate into that? i suppose it would when you...

    Center of the Universe - Is it Possible?

    So we know that galaxies are moving away from us in accordance to their distance and the Hubble constant... but since all motion is relative, we can't very well say which galaxies are moving away from which; to every other galaxy, their neighboring galaxies are moving away from them similarly...

    The Greisen-Zatsepin-Kuzmin limit.

    ok, thanks. I was thinking after i posted that that maybe the energy a photon hits it with depends not only on the speed but of the wavelength, since low-frequency photos are called 'low-energy' photons iirc.. and since the doppler effect applies to light, that would make the impact relative to...

    The Greisen-Zatsepin-Kuzmin limit.

    So I'm reading http://digg.com/general_sciences/13_things_that_scientists_can_t_explain?t=5526450#c5526450 (a great read), and number 3 is this: """ 3 Ultra-energetic cosmic rays FOR more than a decade, physicists in Japan have been seeing cosmic rays that should not exist. Cosmic rays are...

    How to do simulate a resonant frequency?

    Hello, I have a question on how to do something. I'm not sure whether calculus or trigonometry is needed. this is not a homework question. an object will move left and right of a center point in a sinusoidal motion. the period is always the same; the amplitude should change. at any...

    Emulate something in software that has a resonant frequency

    thanks. what's the relation between k and the resonant frequency? also i have another question.. it's about the granularity in time with which i simulate this process. i honestly have no idea how crude it can be. essentially I'm wondering if i could cause a movement only every time it's...

    Emulate something in software that has a resonant frequency

    Hello, I have a question about resonance. Say I want to emulate something in software that has a resonant frequency. It will be receiving pushes and pulls at various intervals, and I want the emulation to reflect how intensely it would vibrate at its resonant frequency as the result of those...
