quantum mechanics

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.

Quantum of Phallus

A gay porn version of James Bond film "Quantum of Solace", starring Briggsy, the arty genius behind "Briggsy Does Brighton". Special agent Briggs Bond saves the world from "breeders" with the help of Q's laser-guided dildos and butt-plug bombs in between bumming every man he can get his hands on and smoking arty cigarettes.
I'm feeling rather horny tonight Cecil. We simply must go and see Quantum of Phallus with our pants down.

Quantum of Solace

- The amount of comfort. All love and friendship is based in the end on that. When the quantum of solace stands at zero, you've got to get away to save yourself. From Ian Fleming's short story of the same name in the Bond collection For Your Eyes Only.
The Governor paused and looked reflectively over at Bond. He said: "You're not married, but I think it's the same with all relationships between a man and a woman. They can survive anything so long as some kind of basic humanity exists between the two people. When all kindness has gone, when one person obviously and sincerely doesn't care if the other is alive or dead, then it's just no good. That particular insult to the ego - worse, to the instinct of self-preservation - can never be forgiven. I've noticed this in hundreds of marriages. I've seen flagrant infidelitiespatched up, I've seen crimes and even murder forgiven by the other party, let alone bankruptcy and every other form of social crime. Incurable disease, blindness, disaster - all these can be overcome. But never the death of common humanity in one of the partners. I've thought about this and I've invented a rather high-sounding title for this basic factor in human relations. I have called it the Law of the Quantum of Solace."

Quantum Sadness

Sadness produced by watching sci-fi, superhero movies and other pop culture media blatantly misuse scientific terms and expect people not to notice or care.
"Seeing Ant-Man run through that 'quantum tunnel' filled me with quantum sadness."
Neil Degrasse Tyson's tweets correcting the scientific principles of "Interstellar" expressed severe quantum sadness.

Quantum Fomo

A condition derived from the realization that out of all versions of yourself in he multiverse, your counciosness is currently trapped in the least interesting or exciting one.
- There's a universe where I am an Olympic Athlete, a world where I am the president, a universe where I am a porn star, a...

- Dude, avoid Quantum Fomo. It's an inescapable rabbit hole.
