For over two thousand years, human beings have had a notion that all matter could only be broken down to a certain point, and beyond that would only be a sample which displays its characteristics. Democritus, an ancient Greek philosopher, named this unit “atomos,” which means “indivisible.” Two thousand years later, modern human beings adopted the name “atoms” to address these particles, which are now known to be constructed of even smaller particles, one of …showed first 75 words of 786 total…

An electron and neutrino emerge from the virtual W- boson in stage eight, and a u quark and d anti quark emerge from the virtual W+ boson. In stage nine, the b quark and anti quark , electron, neutrino, u quark and d anti quark all move away from one another.
