only the bone shows.

This haiku came to my mind yesterday while I was walking in the streets thinking about matrices and graphs. I am supposed to give an introductory lecture about them for undergraduate students in a few weeks, and it seemed like a good reason to finally write a post about mathematics.

Know your brain!

Aside from mathematics, I have other interests. Ever since I started to use my brain for mathematics, I am interested about how thinking works. Since problem solving is my day job, I have plenty of opportunities to observe my cognitive processes and I have a passion for optimizing my brainworks. Thinking about thinking is a very interdisciplinary field, ranging from neuroscience to psychology, and I find a lot of joy in reading about it and trying to adapt it in practice.

I am no brain scientist, merely a brain user (most of the time, at least), therefore these posts will serve as a “How to use your brain 101”, rather than an exquisite scientific investigation.

We jumped inside our car (without roof, of course, as the Stalker requested), then slowly started our trip into the Zone. After sneaking past a few soldiers… wait, no. Scratch that. Here is the real story of our trip into the Chernobyl exclusion zone and to the ghost city Pripyat.
