The Dirac Equation: The Most Important Equation You’ve Never Heard Of
It is my ambition, one day, to understand all the math in this: The Dirac Equation: The Most Important Equation You’ve Never Heard Of.
5 Methods for Differential Equations
This was interesting: Physics Students Need to Know These 5 Methods for Differential Equations. It mentioned List of Laplace transforms. Also it looks like duckduckgo has a new “Assist” feature!
How Math Becomes Difficult
This is a really great overview of a pretty big chunk of mathematics: How Math Becomes Difficult

Learning the Art of Electronics: A Hands-On Lab Course 2ed
I have been sad for some time that Learning the Art of Electronics: A Hands-On Lab Course is out of print. Little did I know, they have been working on a second edition! The revised edition is due out in March 2025. Excellent news! I don’t usually pre-order books, but I will pre-order my copy of Learning the Art of Electronics: A Hands-On Lab Course 2ed. There’s more info on the book’s website: learningtheartofelectronics.com.

In this video I take a look at God Created the Integers edited by Stephen Hawking and published in 2005.
Hawking’s other book which I mention in this video is On The Shoulders Of Giants.
I am sorry that my pronunciation of European names is kind of terrible. While working through the book I made some notes on my wiki about pronouncing various names: God Created the Integers.
At 12 hours (the YouTube maximum video length) this is my longest video so far! If you do watch the whole thing through to the end, you are my type of person, so please do let me know! :)

Today I discovered a new YouTube channel Stuff Made Here. They had this fun video: What if we made a camera that sees in reverse?
What is elliptic curve cryptography?
The following quotation is taken from Elliptic Curve Cryptography for Developers.
What is elliptic curve cryptography?
First, there are no ellipses. Second, there are no curves. So why is it called an “elliptic curve”? The primary reason is history. Performing integrals of the elliptical orbits of planets gave rise to formulas labeled elliptic curves. These formulas were then used in other areas of mathematics, and the label stuck.
The areas of mathematics used in public key cryptography involve number theory (the properties of integers), combinatorics (the study of counting), and finite fields (sets with finite objects and specific rules). Elliptic curves are used in just about every area of mathematics. This makes studying elliptic curve math very difficult because it is hard to determine what you really need to know and what is just really interesting.
For example, elliptic curves have been used for factoring numbers and solving Fermat’s Last Theorem. In chapter 3, I explain how elliptic curves on the complex plane are used to understand elliptic curves over finite fields. It’s all interesting but not necessarily applicable to cryptography.
