crack-pot n. An eccentric or hare-brained person.
In this book, a proud, self-confessed crackpot puts forth several theories on the greatest mystery in the universe--Time. Physicists don't know what Time is--to them it's just a mathematical variable. Among philosophers, debate has raged for millenia over exactly what Time is--and the debate continues even today. Everyone and everything in the universe, without exception, feels the effects of time--Yet no one knows what it is.
Only one thing is sure: It's perfect fodder for a crackpot.
