I asked this in yahoo, and of the answers no one addressed what I was asking, so I added details to maybe help. First ever post on here, sorry if it's bad. Is it theoretically possible to have energy transfers happen continuously instead of discretely? Does it lead to any problems? I've read on a physics site that "Planck's problem -- and the problem of all other physicists at the time -- was that there was no theoretical reason why anything should occur in whole steps, rather than smoothly. There was no reason why anything should be "quantized." So this implies most physicists thought that a continuous transfer of energy made theoretical sense. I'm not sure I agree with this, but am looking for what you have to say about it. Additional Details Okay, no one answered my question. Maybe I should be even more specific. Could continuous functions, like a polynomial, ever be represented in the real world? Is it possible to take it out of the abstract (mathematics) and into the real world (physics)? ie, nothing is quantized, infinite possible positions of particles, infinite possible intermediate points, infinite possible frequency of radiation... can this theoretically make sense?
