I am an engineer, and I really like technology and science. One of my favourite web comics for several years now is xkcd.com. The author is a physicist and has a very interesting view of the world. Lately he has expanded his universe and have introduced a new site called “What If?”.

The site is highly recommended to everybody that ever had a slight interest in physics, mathematics or science in general. The author has created two articles so far, but check them out.
