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"?
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?

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!
