# Qed

What is Qed?

### 1.

Originally Latin meaning "quod erat demonstrandum" or "which was to be shown or proven", now used mainly by physics students to insult someone when something is proven wrong or false, typically with the words Mother Fucker added for effect.

Ha! Your wrong.. QED mother fucker!

### 2.

An abbreviation of the Latin phrase "quod erat demonstrandum". It literally translates as "which was to be demonstrated", and is a formal way of ending a mathematical, logical or physical proof. It's purpose is to alert the reader that the immediately previous statement, which naturally was arrived at by an unbroken chain of logic, was the original statement that we were trying to prove.

"I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing."

"But," say Man, "the Babel fish is a dead giveaway, isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED."

"Oh dear," says God, "I hadn't thought of that" and promply vanishes in a puff of logic." -- Douglas Adams, from "A Hitchiker's Guide to the Galaxy"

Proof that x + 3 = 0 if x = -3

x + 3 = (-3) + 3

= 0

QED

### 3.

1) From the Latin 'quod erat demonstrandum', a mathematical term meaning that a proof is complete.

2) A mathematician's way of saying "OH SNAP BITCH!"

"So you see, by this simple proof, your theory is wrong and mine is correct. QED!"

### 4.

Mathematical jargon for "Booyah!"

"So you see, by this simple proof, your theory is wrong and mine is correct. QED, bitch!"

See proof, acronym, jargon, mathematics

### 5.

After proving something in mathematics, used to indicate that said proof is complete.

Prove that x+3=0 when x is -3...

x+3=0

x=0-3

x=-3 QED

### 6.

Quantum Electrodynamics: a branch of quantum theory describing the interaction of particles with photons. It's main proponenet was Richard Feynman, creator of the ever-popular 'Feynman diagrams.'

"quantum electrodynamics describes all physical phenomena except gravity, radioactivity and nuclear physics; there is no significant difference between experiment and theory" Feynman.

### 7.

What someone writes when insecure about his abilities as a physicist or mathematician to make themselves feel smarter than they likely are. Typically used by douchebagswho think they are doing something amazing by proving a problem from a textbook. Usually follows a terribly formed proof which lacks rigor or reasoning.

"x+y=2. Clearly, z=4, QED."

"You're obviously incorrect, as is seen without proof. QED"
