I think we can't say "mechanics" - we - in best cases - can say only "Quantum Physics" ! We will never find the mechanics of all quants...
Real means equal to physical reality.
Max Planck is said to be the first who understood the possibility to divide a uranium kernel. Is the power of the first atom bomb of Manhatten Project based on massless energy only?

If I take the formula for Electromagnetic Energy of a photon (E= hf) h is a (Planck) constant value and f can be a common positiv number. Is f a real number or an integer? Quantisation of photon...

The question is because in QFT a field can be between bosons. For me a field is a vector from one (local) point to another. But how can we measure or compute a boson from such a "point"?

I heard it very much but I don't know the real physical fact. Please don't give links - even not to Wikipedia - that's not motivating enough!

We know mass is a physical property. We know 99% of nucleid mass is organised by Strong Force between protons and neutrons and about 1% is organised by Higgs field and Electro-week Force. How is...

In some Science Fictions we can read about artificial rebuilding of human brains. Can we ever rebuild life before knowing where the border between organisms and dead objects is?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
