I buy many books at garage sales this has been on my shelf for a while. This is a book that creates in me a curiosity as to were we have been ,are and going. Written in 1986 it would be good to read sequel today in 2020 about what discoveries there have been since. I have searched but found none. I'm now 88 years young and only regret that I had not discovered these topics 68 years ago.
