I am AGSK1235. AG are my initials, SK stands for SKeptic and 1235 are the first 4 prime numbers (Some mathematicians will argue that 1 is not prime, based on updated definition of prime numbers). I am originally from Israel and now lives in Boston, MA. I have a DSc. in EE/CS with specialty in Information Theory, but have transferred to the business side of high-tech startups about 25 years ago. I love brain challenges - solving riddles, identifying thought fallacies, especially around logics and probability. Also love exploring the outdoors by foot and on bicycles. I am excited about the opportunity to apply critical thinking principles to fine-tune the global knowledge base and there is no better place to do this than Wikipedia!
