### ⭐⭐ 







  
  
    Great is you like hypothetical math.
  

*by А***R on Reviewed in the United States 🇺🇸 on December 7, 2022*

I bought his book because it was referenced in several other books I have been reading. It is written by a venerable former NASA engineer. Being an Engineer myself, I was interested. The book mainly centers around celestial mathematics based on observation of objects visible in the sky without a telescope, that he says early civilizations could have not figured out on their own. Well when you have nothing else to do at night but look at the stars, you make observations ad figure things out.... Also I have fact checked many of the other items he mentions in the book, finding out that they are all bogus. The guy has a great imagination, and make a lot of money from this book. I am surprised that this book is quoted as fact in so many places.  Oh and one last thing. Even thought this book is in paperback, you would think the printing would be clear and crisp. In many places it is not and the text is faded and poorly printed.

    A 'different read'
  

*by G***O on Reviewed in the United States 🇺🇸 on July 3, 2021*

This book opened my eyes and connected a lot of the remaining 'dots' I've had for a long time. If you're into this subject matter, this book will be hard to put down once you start reading it. Rainy night, turned my cell phone off, read it from cover to cover.

    It's better to just formulate an hypothesis
  

*by H***R on Reviewed in the United States 🇺🇸 on March 5, 2015*

This was a very detailed exploration into the mathematical relationships of calendars, time, measurements, navigation, and other facets of the human experience.  There is a lot of food for thought here, and really makes you wonder where things really got started.  I was going to give this 5 stars, but I think the author (who has top credentials), went just a little overboard with assumptions.  He then uses those same credentials to more or less add weight to things that are really in the "beliefs" category, and not really scientific fact.  It's okay to speculate on things, but make sure to keep facts and beliefs separate.  It's better to just formulate an hypothesis, and leave it at that.Besides that, the author really knows his math, and drives numerous calculations home to support various theories.  For that, it's quite interesting, but could be somewhat boring to those who are not inclined towards numbers.
