what is DES DATA ENCRYPTION STANDARD (DES)
The Data Encryption Standard (DES) specifies two FIPS approved
cryptographic algorithms as required by FIPS 140-1. When used in conjunction with American
National Standards Institute (ANSI) X9.52 standard, this publication provides a complete description
of the mathematical algorithms for encrypting (enciphering) and decrypting (deciphering) binary
coded information. Encrypting data converts it to an unintelligible form called cipher. Decrypting
cipher converts the data back to its original form called plaintext. The algorithms described in this
standard specifies both enciphering and deciphering operations which are based on a binary number
called a key

The entire field of mathematics summarised in a single map! This shows how pure mathematics and applied mathematics relate to each other and all of the sub-topics they are made from.
If you would like to buy a poster of this map, they are available here:

To err is to human, and I human a lot. I always try my best to be as correct as possible, but unfortunately I make mistakes. This is the errata where I correct my silly mistakes. My goal is to one day do a video with no errors!
1. The number one is not a prime number. The definition of a prime number is a number can be divided evenly only by 1, or itself. And it must be a whole number GREATER than 1. (This last bit is the bit I forgot).
2. In the trigonometry section I drew cos(theta) = opposite / adjacent. This is the kind of thing you learn in high school and guess what. I got it wrong! Dummy. It should be cos(theta) = adjacent / hypotenuse.
3. My drawing of dice is slightly wrong. Most dice have their opposite sides adding up to 7, so when I drew 3 and 4 next to each other that is incorrect.
4. I said that the Gödel Incompleteness Theorems implied that mathematics is made up by humans, but that is wrong, just ignore that statement. I have learned more about it now, here is a good video explaining it: https://youtu.be/O4ndIDcDSGc
5. In the animation about imaginary numbers I drew the real axis as vertical and the imaginary axis as horizontal which is opposite to the conventional way it is done.

Ari Juels visits Google's San Francisco office to present his book "Tetraktys". This event took place on Mar 5, 2010, as part of the [email protected] series.
International computer security expert Ari Juels brings his extraordinary talents to fiction in a literary thriller that spans the centuries. Cryptographer and classicist Ambrose Jerusalem is a UC Berkeley graduate student with a beautiful girlfriend and a comfortable future, until the National Security Agency recruits him to track a strange pattern of computer break-ins. Individually, they might not mean much a State Department officialdiscovers a peculiar series of incriminating appointments in her computer calendar dating back to 18th century France; a corrupt president of the International Monetary Fund is startled by an oracular voice from his computer charging him with crimes against divine numerology and God but together, they provide disturbing evidence that someone has broken RSA encryption, the security lynchpin protecting the world s computer systems. Even more bizarre, a secret cult of latter-day followers of Pythagoras, the great Greek mathematician and philosopher who believed reality could be understood only through a mystical system of numbers, appears to be behind the attacks. With his deep knowledge of both cryptography and classical antiquity, Ambrose is the government s best chance to uncover the cult. Soon Ambrose discovers he is not only the hunter but the hunted, and the game is not simply code-breaking, but a deadly plan to alter the fate of the world.

In mathematics, especially in geometry and group theory, a lattice in is a discrete subgroup of which spans the real vector space . Every lattice in can be generated from a basis for the vector space by forming all linear combinations with integer coefficients. A lattice may be viewed as a regular tiling of a space by a primitive cell.
Lattices have many significant applications in pure mathematics, particularly in connection to Lie algebras, number theory and group theory. They also arise in applied mathematics in connection with coding theory, in cryptography because of conjectured computational hardness of several lattice problems, and are used in various ways in the physical sciences. For instance, in materials science and solid-state physics, a lattice is a synonym for the "frame work" of a crystalline structure, a 3-dimensional array of regularly spaced points coinciding with the atom or molecule positions in a crystal. More generally, lattice models are studied in physics, often by the techniques of computational physics.
