We know a beam of light, which is a set of Photons, is polarizable only horizontally or vertically.
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?

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?

I have an issue with SEM imaging of liposomes. When measured by DLS, they appear to be around 120 nm, but when using SEM with simple air drying, they appear much larger, around one micrometer.
