Title: Representing fractions as sums of reciprocals in binary number systems
Speaker: Dr. Peder Olsen
Abstract: Palindromic pandemonium focusing on palindromes in number systems with only 0 and 1. The question is if we can find a number system using only the digits 0 and 1 such that every fraction can be written as a sum of reciprocal palindromes in that number system. I encourage everyone to try before we meet. This the session will be interactive, so even a failure to succeed will be worth it. Be prepared to add fractions and solve quadratic equations. We discussed related questions in the prior two years; if anyone wants to see what happened the last two years, the last talks are available here: https://github.com/pederao/palindrome/tree/main/talks/wamc and even more information is available here:
https://github.com/pederao/palindrome/tree/main.
For those that understand python you can even play around with some of the code. This talk doesn't require you to have attended the past lectures and is open to all.
