I use Wikipedia heavily and got started editing as a way to give back to a community I benefited from. I make general edits correcting typos and bringing WP:MOS compliance on all articles, but my special area of knowledge is physics, particularly quantum information. The two Wikipedia pages I have created are related to that topic:

• Karl Kraus (physicist) (translated from the German Wikipedia with the aid of Google translate)
• Quantum stochastic calculus
