Today’s the birthday of astronomer Edwin Hubble.

Shamelessly using this to say there’s a chapter about him in my last book, putting his work in the context of the early 20th C debate about the nature and size of our Milky Way galaxy.

Today's recommended book is "Logicomix" by Doxiadis and Papadimitriou. This is a wonderful graphic novel about Bertrand Russell's ultimately doomed attempt to discover a true logical foundation for mathematics. #comics #graphicnovel #mathematics #logic

A number is perfect iff the sum of its proper divisors equal the number. For instance, 2^(p-1)(2^p-1) is perfect iff 2^p-1 is a Mersenne prime. Therefore, 6,28,496,8128,...are perfect numbers. Nobody knows if there is a odd perfect number

a natural number is perfect if and only if is equal to the sum of its proper factors, for example, 6 and 28 are perfects (check it), nobody has ever found an odd perfect number. Perfect numbers are related with Mersenne prime numbers but I can not explain that here, www.youtube.com/watch?v=5m14...

This is my Commodore 64 that I received for Xmas 1983. I LOVE it and use it the most out of all my Commodore computers. It sits on the desk I built for it in 1984 in 11th grade woodshop.
