A week ago, I chanced upon a good blog - Good Math, Bad Math. Basically, its a blog that discusses a wide range of science, from computer science to mathematics and physics, but with an emphasis on mathematics. The blog is written by a really cool guy - Mark Chu-Carroll, a PhD Computer Scientist working at Google. In many ways, the blog offers a platform for intellectual discourse - criticising and highlighting bad/flawed science and mathematics. This is a reminder that the very notion of science, no matter how grand it may seem, is susceptible to those who either manipulate it for their own means (e.g. General Relativity is not about all things being relative [not absolute]... just as relativistic speed do not refer to speed of light being undefined.), or confuse it unintentionally.
Currently, I am reading Mark's recent articles on Graph Theory.
