Sword in The Darkness Imperial Stout, brewed by the brothers of the nights watch. First in hopefully a series of rendered asoiaf/ GoT fictional beers. Meant to be beers that could actually exist in the asoiaf world.

umm awesome!
Whaaaat?

Math AND politics humor. Flawless, flawless victory.
There is actually some interesting research showing that people care much more about an isolated individual’s suffering than the suffering of many people.
A representation of the quantum Fourier transform on n qubits as the tensor product of n single qubit operations.
This decomposition allows for the quantum Fourier transform to be implemented on a quantum computer efficiently (fast enough for practical purposes). It is used in various algorithms, including Shor’s algorithm, which is an algorithm for factoring large (200+ digit) integers.
The computational task of factoring large integers on a classical computer takes so long that the government, banks, and the internet rely on this difficulty to keep their information secure from the public (RSA cryptography).
So if you have a large scale quantum computer, you could have the ability to hack and render the RSA cryptographic protocol obsolete!
The thing is, quantum computers are really hard to make. However, in 2001 IBM researchers in the foothills behind my house managed to use a quantum computer to factor the number 15 into 3 x 5!
Nice. Don’t follow it too well, since I am not a quantum computation guy. Why is there an n above and an l = 1 below the sign for the direct product?
