Argen good to hear back from you. Your recommendation of the Australian web site with the Feynman lectures was just what I needed. I went on to read QED and Six Easy Pieces, along with the less technical the Joy of Finding Things Out.
1. Yes, physics is taught historically, classical first and then the historical fumbling into the quantum. And at the end of this I think Feynman should be required reading, because he emphasizes the "unknowable physicality of quantum particles" which he believes will perhaps never be deciphered but can be known via mathematics and his diagrams.
2. Feynman says all the strangeness of quantum mechanics can be seen in the double slit experiment where an electron beam hits a target encompassing two slits. It is postulated that an electron goes thru either one slit or the other. If we do not follow how the electron goes (give it energy to enable our sight) we get an interference pattern (on a screen behind the slits) making it seem that the electron went thru both slits simultaneously (the way a water wave does). Hence there is something wrong with the postulate that the electron (which was considered a thing) goes thru one slit or the other.
3. Heisenberg came to the conclusion (probably first) that the electron is not a thing and that it and all particles must obey an uncertainty principle. It is this uncertainty principle which prevents us from saying that the electron went thru one slit or the other. So, we still can believe that the electron goes thru one slit or the other but we cannot determine which one because of the uncertainty principle.
4. I believe there is another cleaner way to look at why the electron goes thru both slits simultaneously. I postulate that the electron and all particles (including photons) move in a peculiar way. They appear at a time and place and they reappear at an adjacent time and place. This way of moving fits very nicely with the deBroglie wave equation thus the name Digital Wave Theory. The electron approaching a double slit to within a wavelength makes a hop and appears on the other side without having to invoke uncertainty. The electron still obeys all of the Feynman rules, but now there is no mystery about how it can go thru both holes simultaneously. And I believe the nature of gravity comes about and can be derived from the way that particles move by hopping over time and space.
5. Here is the reasoning about photons having mass:
a. I start with a particle with mass and say it moves by hopping.
b. The particle is always moving and thus hopping because it is a wave according to deBroglie.
c. I derived a minimum velocity that this particle of mass m can have. It cannot be zero because it must move to be a wave.
d. The equation derived for the minimum velocity is a second order polynomial that has two roots. When plotted one root looks like a slow moving massive particle. The other root looks like a photon moving very, very close to c except at very, very high energies.
e. Thus, the general particle with mass m that I started with is really two particles, one can be seen as ordinary matter the other can be seen as a photon. These photons as seen in the plot show in the essay travel slightly slower than c and this speed varies with wavelength.
f. Photons have mass because they are one of the solutions to an equation that starts with a generalized particle with mass. The consequence of having this mass is that they do not quite travel at c, but approach it so closely that our current instruments and experiments are not yet in range and least 10 more digits of accuracy is required to see this at visual wavelengths.
6. I have this one criticism of Feynman in that he did not explain why electrons moving uniformly in a straight line emit and absorb photons. Perhaps I missed something that was obvious? I request that anyone who knows to pass the information along to me. So, Arjen when you find out let me know.
7. This theory of particles moving as digital waves fits very nicely with superconductivity. At absolute zero the electrons still have velocity and can sustain a current. The material it is moving through has a crystal structure that provides a clean landing spot for an electron if it is moving with hops at just the right wavelength. When the velocity of the electron matches the spaces available for it to land and superconductivity results.
Arjin, this contest gets somewhat boring when the judging starts, and it was a pleasure to respond to your post. I think I may have gotten a little long winded. Thanks for the opportunity!
Best of Luck to you and all,
Don Limuti
