I am a Wikipedia User. I used Wikipedia extensively as a resource to get me through my Masters & PhD.
My edits are most frequently TALK requests to provide comprehensibility for non-mathematicians, e.g. for physicists and computer scientists. I occasionally edit a science related article for readability, and critique SP & GR related articles when they lead to the wrong conclusions.
My fields are: Aerospace & Astronautics, Physics, Relativity, Information & Computer Sciences. I am currently studying QM & Q-ICS. I would answer article-author's questions when posed.
