What is Quantum Physics⁉ Neil deGrasse Tyson on #physics #quantum #science

Okay I guess it is time for my favorite Physics Joke:
An electron and a positron walk into a bar:
The positron says to the electron:
"You are round."
"Are you sure?"
"I'm positive. "
Hee hee.

With the exception of "they exist intangibly...I am right with the good Doctor." There is a growing bevy of tangible traceable predictable properties of quantum objects which we can, and have experimented with. The Q bits and Quantum Computing, the microtubules in the brain that we recently discovered work as quantum objects, and may (finally) give us some breakthroughs on the "Hard Problem" in Neuroscience (Consciousness), and in Engineering, new materials formed based not on chemistry or metallurgy, but on quantum chemistry are showing up in Labs. Those magnetic chambers that can hold a "Sun in a jar" for a few milliseconds, work off of quantum rules.
And then the speculative stuff is off the charts. Here are just two:
1) Photons move at the speed of light. For them, there is no Time. So does a photon "know" where it is going before it leaves? When it hits my eye, it was in the same moment as when it left the sun however many of thousands of years it took to get to the surface. And did it choose to find my eye?
2) Some Physicists speculate that there might only be one electron. One. Wrap your head around that for a bit.

I don't understand quantum physics, I barely could understand Classical Physics. I took me decades to understand an apple falls in a straight line, the displacement of SpaceTime is why I percieve it to be a curve. Yeah, my head hurts... a lot.

Who am I to disagree with him? I buy it!
