More Busy Beaver Results

I read a blog post about a result I was aware of relating to the busy beaver problem. The result is the following: it is impossible to prove the value of BB(k) in ZFC when k = 7918. ZFC stands for Zermelo–Fraenkel set theory with the axiom of choice. ZFC is basically “an axiomatic system that was proposed in the early twentieth century in order to formulate a theory of sets”. To sum up very generally a set of axioms from which all (?) mathematic theorems can be proven from.

Reading this blog post and trying to understand its impact sent me on a wild ride of reading other interestings bits I want to collect here so I can re-read / finish later. Here they are:

#OneWeek100People by Marc T. Holmes

An urban sketcher I really like is Mark Taro Holmes. I love his simple approach to skeching and the fresh results he gets with a simple 3 step technique that he develops in his Travel Sketching in Mixed Media Craftsy course. I re-discovered his blog lately and wanted to show case some of his work. Every year he hosts a challenge to draw 100 people in 5 days. The artwork I show below are from previous challenges. You can read more about the challenge in this blog post
