The particle number (or number of particles) of a thermodynamic system, conventionally indicated with the letter N, is the number of constituent particles in that system. The particle number is a fundamental parameter in thermodynamics which is conjugate to the chemical potential. Unlike most physical quantities, particle number is a dimensionless quantity. It is an extensive parameter, as it is directly proportional to the size of the system under consideration, and thus meaningful only for closed systems. A constituent particle is one that cannot be broken into smaller pieces at the scale of energy k·T involved in the process (where k is the Boltzmann constant and T is the temperature). For example, for a thermodynamic system consisting of a piston containing water vapour, the particle number is the number of water molecules in the system. The meaning of constituent particle, and thereby of particle number, is thus temperature-dependent. (Wikipedia).

What Exactly IS a Cross Section pt. 1: Cross Sectional Area
Today I I break the world record of longest video explaining cross sectional areas. I spend a good deal of time deriving and giving geometric arguments for the equations most textbooks would simply define for the cross sectional area if one has a single target, or sheet of targets.

Why are there only 2 types of fundamental particle? (And why are there more in 2D?)
Every particle that exists is supposedly either a boson or a fermion. But why are there only two types? Are we just not looking hard enough? Well the reason has to do with the topology of a strange kind of space... And it turns out that if we lived in 2D flatland, things would look very di
