or:What is the physical significance of the mathematical expression "Q = +-ne" , all symbols've meaning

or:Q=+-ne, symbolises quantisation of charge. The physical significance of this equation is charge that we find in universe is always a integral multiple of e, i.e., we can have +-(2e, 3e, 4e.... etc). But we can never get 1.5e, 2.7e etc. Because if we get 1.5e, it means (1e + 0.5e). In universe we can get one electron but can't get half electron, to make 1.5e. So 1.5e never exists. The above discussion is the physical significance of your question.
