A good website

http://en.wikipedia.org/wiki/Portal:Physics and http://en.wikipedia.org/wiki/Portal:Mathematics are very good websites. These websites are specialized Wikipedia's sites that show topics of physics and math. The first link shows the Physis's portal. It has a lot of topics, for example: Clasic Mechanic, Quantum mecanic, electromagnetism, waves, Analitic mecanic, acoustic, optics and relativity. Also this site shows a selected article, phisics news, a special portal named "Did you Know" etc. The second link shows the Mathematic's portal. It has topics about Algebra, Foundations, Number theory, Discrete mathematics, Analysis, Algebra, Geometry and Topology. Also this site has some sections like "Selected article", "Did you know", "Picture of the month", etc. The first time what I visit these websites was in my lonely holiday, I had a lot of time and I started to read Wikipedia's articles. I like these sites because has a lot of link to read interesting topics related with my career, I like read science articles in specialy Number Theory and Relativity articles. I read these websites because I try to learn things to win a Nobel prizes or a Fields Medal in the future.
