Godwin's number

n. The average number of replies in a thread before a Nazi reference is made. Generally, Godwin's number is regarded to be twenty, based on the equation: G=(d(Q1)+d(Q2)+...+d(Q)n)/100*n^(-n)
where Qn is the intelligence of user n, n is the total number of forum users, and d is a damping function that prevents the intelligence (or lack there of) of one user to influence the others too much.

As he typed his polemic on the forum, John brought the discussion one step closer to Godwin's number.

To prevent discussions from getting out of hand, OmniForums will now calculate Godwin's number based on the first two threads.

Roman Numeral

Roman numerals are numerals that replace the normal Arabic numerals. They use letters such as
I, V, X, L, C, D, and M. Each letter has a value and cannot be repeated more than 3 times. A bar over a roman numeral means it has been multiplied 1000 times so you don't have to write numbers that are like 20 numerals long.

I am an expert at roman numerals.

take a number

Figurative: "If you want to discuss this topic with me, you will need to wait your turn, as there are any number of others who wish to do so who got here before you did."

Comes from a line control mechanism that is found today with decreasing frequency, where one is requested to take a numbered ticket from a strategically placed dispenser and accordingly wait for that number to be called.

Your computer just blew up? Take a number, I've been getting calls on that all day.

number plate

Identifying plates fitted to vehicles in the UK (and elsewhere), carrying the vehicle's registration number.
Similar to License plate, Registration plate etc.

In the UK the reg. no. belongs to the vehicle, not the driver, and contains information about the age of the vehicle and the region in which it was first sold. The system is administered by the DVLA.

The reg. number is alphanumeric, and takes the form AB12 CDE on vehicles registered after 2001, or A123 BCD on vehicles registered before 2001.

Some scouse git has stolen my number plates. Now I will be done by the police.

jimaginary number

A portmanteau of "j" and "imaginary" for the imaginary component of a complex number. This means the same thing as Imaginary Number, and typically this number would have an italicized i after it. In electrical engineering, the letter "i" has other and more apparent meanings, so to avoid confusion we pick the next letter, j.

Compare imaginary with jimaginary number
Sheldon would use 1 + 2i.
Howard would use 1 + 2j.
