Black (code)

The Black Code (more formally, Military Intelligence Code No. 11) was a secret code used by US military attachés in the early period of World War II. The nickname derived from the color of the superencipherment tables/codebook binding. The code was compromised by Axis intelligence, the information leak costing a great many British lives.

Making Black Holes is HARDER than you think!

Black holes aren't just a product of general relativity, but also require quantum mechanics. In this video, we'll take a look at how the Pauli exclusion principle and Heisenberg uncertainty principle apply to black holes. Making a black hole is actually quite difficult. ___________________
