Who is Simon Singh?
Simon Singh is a popular science author and several times speaker for Edinburgh Skeptics. He wrote an article for The Guardian in 2010 about chiropractory practice which promoted the British Chiropractic Association to sue Simon for libel, which he successfully defended. As a result we can legally say the "BCA promoted bogus treatments".
Simon went on to start The Good Thinking Society to promote skeptical activism.
His books include: Fermat's Last Theorem, The Big Bang and The Simpsons And Their Mathematical Secrets.
