OK My question was too vague. I will ask much more specific question.

I was reading a book, 'Introducing Quantum Theory' by J.P.McEvoy, and I find it difficult to understand in details of Maxwell Distribution, Thermal Equilibrium, Fluctuation, Wein's law and Planck's quantum theory, so I am finding it difficult to follow Einstein's explanation of photoelectric...

But how does Earth's centre being pulled stronger than the furthest of the Earth from the Moon affects the Earth itself, to have the tide to occur on the furthest side? The only reasonable explanation of such forces cancelling out I can think of is Earth falling towards the Moon.

There was a thing that kept me wondering for several years, which no science teacher managed to explain. Why does gravitational pull of the Moon causes two tides on Earth at the same time? Would'nt it be more logical for the tide to only occur directly under the moon, nowhere else, because...

While I was looking up E=mc^{2}, I have learned such formula only applies to stationary objects and for kinetic object, the formula is this: E_{r}=\sqrt{(m_{0}c^{2})^{2}+(pc)^{2}} Where E_{r} is relativistic energy and m_{0} is rest mass In the formula, what is p and what is (pc)^{2}...

So, do you mean, without weak interaction, such annihilation is impossible?

I've been searching about particle-antiparticle annihilation and I've been wondering whether it was possible for particle to annihilate with antiparticle that is not its pair? Can annihilation occur with collision of different particle-antiparticle quarks(e.g. up antiquark and strange quark)...

This is an Youtube video made by a physicist. It is made with simple drawing and it is easily understandable.
