Gauss map, Euclidean algorithm, and continued fractions
The Gauss map [1] is the function where ⌊y⌋ is the floor of y, the greatest integer no larger than y. I’ve written about this map a couple times before. First, I wrote about how this map is measure-preserving. Second, I wrote about the image at the top of the

The goal of this post is to unpack a remark in [1]: … we can say this in fancier terms. Fix a field k …. We say that an elliptic curve E defined over k is that functor which … Well that is fancy. But what does it mean? Looking

The geometric description of addition of points P and Q on an elliptic curve involves four logical branches: If one of P or Q is the point at infinity … Else if P = Q … Else if P and Q lie on a vertical line … Else … It
Read moreRational height functions
Mathematicians often speak informally about the relative simplicity of rational numbers. For example, musical intervals that correspond to simple fractions have less tension than intervals that correspond to more complicated fractions. Such informal statements can be made more precise using height functions. There are a variety of height functions designed

If you ask someone a question and they say “yes” immediately, that gives you different information than if they pause and slowly say “yes.” The information you receive is not just the response but also the time it took to generate the response. Encryption can be analogous. The time it

Streamsync is a new open-source framework that creates data apps. Streamlit allows you to build the user interface using a visual editor while retaining the power of Python in the backend. It’s all contained in a pip-installable packageStreamsync’s visual editor, Streamsync Builder.The OriginsAbout a year ago, one of my colleagues

An action framework for managers dealing with underperformancePhoto by Patrick Robert Doyle on UnsplashHelping underperformers get out of a productivity rut is one of the trickiest manager tasks. Poor performance can manifest in a couple of different ways. Sometimes, it’s a new hire not meeting business expectations; other times, a trusted
