"The puzzle of quantum physics is that even when the beam of light is so weak that it can be considered to be made of ‘particles of light’ or photons, the spots of light made by individual photons arriving at the screen eventually build up an interference pattern."
"How does each photon (which common sense says can only go through one slit or the other) ‘know’ about the slit it does not go through, and direct itself to the appropriate place on the detector screen?"
"...But, recently, some researchers have carried out the double slit experiment
using electrons, fired one at at a time, to build up an interference pattern."
"If he is right, all those textbooks that talk about photons as particles will have to be rewritten, and many lecture courses revised."

"The photoelectric effect results in electrons being ejected from a metal only by photons with energy above a specific value characteristic of the metal. One photon is absorbed to knock out one electron. ... All of these interactions indicate that if electrons exist, photons also exist."
I guess I've always been uneasy about the notion of an 'object' with no mass except when it's moving...
"But according to special relativity, light ALWAYS travels with the light speed c, and is NEVER at rest. And so it has zero REST mass. which means that though photons don't have rest mass, they do have energy and thus they have mass. The photons are wave particles."
It's interesting that Tesla who you might say had an almost magical 'grip' on electricity, even literally sometimes, didn't believe in electrons
"Tesla was also a physicist who studied in college such courses as analytic geometry, experimental physics and higher mathematics.1 In his early 1890s lectures at Columbia University, the Chicago World’s Fair and at Royal Societies in Paris and London, building on the ideas of Isaac Newton and Lord Kelvin, Tesla demonstrated and discussed the structure of atoms as being similar to solar systems and wave-like and particle-like aspects to what later became known as the photon. Colleagues he lectured before and corresponded with included many Nobel Prize winners like Wilhelm Roentgen, J.J. Thompson, Lord Raleigh, Ernst Rutherford and Robert Millikan and other scientists such as Elmer Sperry, Sir William Crookes, Sir Oliver Lodge, Lord Kelvin, Heinreich Hertz and Hermann von Helmholtz.
As far as I know, no standard text on the history of physics mentions Tesla even though these ideas would lead to Nobel Prizes when they were further developed by Rutherford and Bohr (with their solar-system description of the atom with electrons orbiting the nucleus) and Einstein’s discovery of the photoelectric effect, which was equivalent to Tesla’s wave and particle-like description of light."
"However, another idea which Tesla discussed was abandoned by modern physicists, and that was the concept of the all pervasive ether. This led to a number of key differences between Tesla’s view of the world as compared to that of Albert Einstein (1879-1955). Tesla disagreed with the findings of Einstein’s Theory of Relativity in a number of ways. As far back as the turn of the century, Tesla thought that he had intercepted cosmic rays emanating from the sun that attained velocities “vastly exceeding that of light.” In the last decade of his life he also claimed that these cosmic rays could be harnessed to generate electrical power. Tesla also saw radioactivity as evidence of the material body absorbing energy as much as it was giving it up."
"Concrete proof that relativity can be violated can be found in George Gamow’s watershed book Thirty Years That Shook Physics. Gamow, one of the founding fathers of quantum physics, tells us that in the mid-1920’s, Goudsmit and Uhlenbeck discovered not only that electrons were orthorotating, but also that they were spinning at 1.37 times the speed of light. Gamow makes it clear that this discovery did not violate anything in quantum physics, what it violated was Einstein’s principle that nothing could travel faster than the speed of light. Paul Adrian Dirac studied the problem. Following in the footsteps of Herman Minkowski, who used an imaginary number i, (the square root of -1) to be equivalent to the time coordinate in space-time equations, Dirac assigned the same number i to electron spin. In this way he was able to combine relativity with quantum mechanics and won a Nobel Prize for the idea in the process (1966, pp. 120-121). That was the upside. The downside was that the finding that elementary particles spin faster than the speed of light as a matter of course went the way of the passenger pigeon. No physicist talks about this anymore."
"What this means is that the entire evolution of 20th and nascent 21st century physics is evolving ignoring this key Goudsmit and Uhlenbeck finding. The ramifications suggest that elementary particles, by their nature, interface dimensions. Because they are spinning faster than the speed of light, the idea is that they are drawing this energy from the ether, a pre-physical realm, and converting the energy into material form."
