What were you doing on the evening of July 20, 1969? If you are at least a baby boomer, you were probably watching Neil Armstrong take "one small step for man, one giant leap for mankind." Sputnik aside, the birth of that monumental achievement probably began with the same question that sparked so many other great feats: "What if?" Where would civilization be if someone periodically hadn't had the imagination and the courage to ask that question, whether their field of expertise was aeronautical engineering, architecture, or biotechnology?
