No escaping linear algebra

"Pure math is beautiful (and occasionally useful) and applied math is useful (and occasionally beautiful). But there's no reason to study fake applied math that is neither beautiful or useful." johndcook.com/blog/2024/04/1…

The letter π was first introduced as a symbol for the ratio of the circumference of a circle to its diameter by the Welsh mathematician William Jones in 1706. π is the first letter of the Greek word "peripheria" (περιφέρεια), which means perimeter.

Mathematics. Transcendent. The global maximum of the x-th root of x occurs at x = e. Nice.

Mathematics. Welcome to Heaven. Graph of the equation y = 1/x. Shiver. e is the unique number larger than 1 that makes the shaded area under the curve equal to 1. bit.ly/3KOmVv6

Continuity 💪

In 1969 Apollo 11, the spaceflight that first landed humans on the Moon, used these 30 lines of code to calculate transcendental functions like sine and cosine essential for navigation
