A WORLD OF "WHAT-IF"s... Had Albert Einstein and Arsenio Hall lived at one and the same time, could it have been something the latter said--"Jack Sajak, as an emcee, is square!"--to provide the former with the breakthrough for his now world-renowned equation, E=mc2? Had The Beatles and Adolf Hitler met, the latter commenting off-handedly, "Yes, I did once get Meyer Rothschild's attention by screaming, 'Hey Jude!'"--could the idea for the former's famous song have taken root, right then and there? No one can know for sure, but internationally renowned author William Maltese can and has conjectured just such what ifs?.
