Sure. The easiest is with a phosphor screen or a cloud chamber. -

Like.
For example, the electron hits a detector at some location. This paper describes a double-slit experiment with electrons (instead of... -

The math model predicts a probability for a measurement result.

That there appears to be some inevitable stochasticity in the world. QFT respects the causal structure of relativity, so has clear...

Or if you ask vague enough questions without putting in any effort to actually learn the material. "A mechanism for randomness [would...

The probability distribution still has causes and effects.

bhobba replied to the thread High School Einstein equations don't work at large scale?.Poincaré had already discovered a significant amount, so shock isn't the word I would use. Its significance, IMHO, was in showing the...

Love.
Not only that, but I think it's difficult even now for scientists to get others to feel the shock--to the average layperson, QM might... -

And it still is. That’s not a my take on the history, and I’m thinking that you are still overestimating the extent to which new...

He derived the result that if a body emits radiation of energy ##L##, its invariant mass (in modern terminology) is reduced by ##L /...

bhobba replied to the thread High School Einstein equations don't work at large scale?.As explained above, it does fit, but only at low energy scales. In fact, it is suspected that all the so-called Standard Model is like...

##\gamma## plays many other roles besides the time dilation factor. That "derivation" assumed that ##E_0 = m c^2##, since you wrote...

Quantum field theory is fully consistent with special relativity and works in curved spacetime too. What we don't have a good model...
