Although I had supported Wikipedia for some time, my reasons remained unclear (even for me) until I had the following experience:
I was in an internet cafe in the city of Kumasi, Ghana in the summer of 2006, when I noticed that the man beside me was reading an article on wikipedia. I realized that he could, for a relatively affordable 7000 cedis an hour (~CDN $1.00/hr), access the information of the world in a way that would have been inconceivable a decade before. Hence, Wikipedia for me embodies one of the most powerful concepts to arise from the internet; free knowledge.
Personally, I am an aspiring physicist and recreational student of history who, while at Queen's University, completed undergraduate degrees in Engineering Physics and History, and a Master's that investigated carbon nanotubes using ultrafast laser optics. I then received a doctorate in physics as a member of St. John's College at Cambridge University as a result of my studies of ultrafast triplet exciton generation in materials for organic photovoltaic devices. Presently, I am researching the optical properties of organic semiconductors and inorganic quantum dots in my capacity as a postdoctoral associate at the Massachusetts Institute of Technology. I enjoy swing dancing, musical theatre, canoeing, ultimate frisbee, and a cappella music . Hailing from Port Colborne, Ontario, Canada, I've acquired a distinct appreciation for the small town life.
I have worked on articles ranging from the MAPLE reactor to Napoleonic history, but primarily work to clean up poorly-written or erroneous articles. I submit my small contributions to Wikipedia and thereby the public domain.
