My Book Making Probability So Easy That a Lemur Could Learn It

Probability involves a lot of extra-mathematical concepts and funny transforms. I have always had a hard time internalizing it. When I heard a couple years ago that Lemurs are actually capable of abstract math, that gave me a bit of motivation to try to finally conceptualize probability in terms of whole numbers, counts, geometric shapes, basically easy-to-remember mathematical primitives. This book might be interesting to folks interested in predictive science, research, or just anyone who may have taken probability or statistics and might like a refresher on some of the edges of these…

In plain words

This book explains probability concepts using simple mathematical foundations like whole numbers, counts, and geometric shapes rather than complex transforms. Written by Patrick Delaney, it targets people working in predictive science and research, as well as anyone seeking to better understand or refresh their grasp of probability and statistics fundamentals. The author approaches the subject through concrete, easy-to-remember primitives designed to make abstract probability intuitive.

Lemur see, lemur calculate. A visual probability handbook for aspiring, curious primates. Lemurs can represent approximate numerical values and have numerical rule-making abilities - so the author thought, "Well if a lemur can do that, why can't I do that too?" This book is an attempt at making practical probabilistic concepts much easier to grasp and internalize by tapping into the highly-visual, primitive part of our brains.

    I made a web game called Almost Pong▲1,135

    Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
