A branch of physics in which the measurable qualities (position, momentum, energy) of a system are described by "observables." The system, upon measurement by the given observable, after being in a superposition of multiple states, collapses into one of a variety of states allowable by the Schrodinger equation. The exact state the system collapses into, is probablistically determined.
X|s1>=x1|s1>
In this example, |s1> is the system being "measured" by the observable X (X denoting the position observable, allowing us to see where the system is within space.) We obtained |s1> as a single state, from a previously superposed (|s> = |s1>+|s2>+|s3>+...)state through an earlier measurement, which collapsed |s> into |s1>, and allowed us to measure the value x1 for its position. In quantum mechanics, all of this information is encoded in the language of vector spaces, as well as linear algebra, and expanded into whats known as a hilbert space (can be thought of as an infinite dimensional vector space).
I'm probably going to get all thumbs down for this, but that's cool, you guys are all the same audience that jerks it to youtube, and probably added a new definition for "poop" or something stupid like that on this site.

Get the quantum mechanics mug.The belief that thermodynamic systems can be expressed using statistics. It is mostly used to more accurately express a system where there are many microstates involving microscopically observable quantities (e.g. kinetic energy of particle 1, 2, 3, ... , n-1, n or Potential energy of particle 1, 2, 3, ..., n-1, n as opposed to quantities like pressure or volume).
What the author of this article should be revising now, Statistical Mechanics (or stat mech as it's more conveniently known) can be described by many physics students as a "cluster-fuck of endless equations and probability distribution functions designed to intentionally screw up their mind altogether".
It is widely known that stat mech is utterly incomprehensible until the actual exam day, when all the nonsensical examples and equations (most notably finding the entropy of an elastic band expressed as a function of the number of links in said band, and the expression of gas molecules as masses on springs) seem to reach perfect clarity and they tend to walk out with at least a 2-1.

"Goran Bunch" recently received his paycheck. Displaying typical munch mechanics, he resolved to spend it entirely on a European satchel, hard liquor, something with rhinestones, and an over-priced gift for an Asian minor (in the hopes of receiving sexual gratification.) Later that night he recalled his countless stupid decisions, but, for some reason, repeated the same actions during the following pay-period. munch mechanics
