Babies and the beta-binomial distribution
About half of children are boys and half are girls, but that doesn’t mean that every couple is equally likely to have a boy or a girl each time they conceive a child. And evidence suggests that indeed the probability of conceiving a girl varies per couple. I will simplify

Suppose the vertices of two triangles are given by complex numbers a, b, c and x, y, z. The two triangles are similar if This can be found in G. H. Hardy’s classic A Course of Pure Mathematics. It’s on page 93 in the 10th edition. Corollary The theorem above

Read moreVector Fields and Fuel Consumption Wrapped in 3D
While poking into the connection between Poisson equations, vector fields, and specialized neural networks, I decided to create custom vector field visualizations and I would like to present a few of the practical applications of calculus. If you own a boat, airplane, or car, by the end of this post

Here’s something I found surprising: the powers of a 2×2 matrix have a fairly simple closed form. Also, the derivation is only one page [1]. Let A be a 2×2 matrix with eigenvalues α and β. (3Blue1Brown made a nice jingle for finding the eigenvalues of a 2×2 matrix.) If α
