The title of this monograph, while intended to intrigue and attract the otherwise unresponsive reader, is not whimsically conceived. Of course, the historical figure of mathematical fame known as Pythagoras, born on the island of Samos in the 6th century B.C., was Greek, not Chinese. But there is another "Pythagoras" equally deserving fame. He is the man who first proved the proposition that "the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse." For hundreds of years this theorem has borne the name of Pythagoras of Samos, but was he really the first person to demonstrate the universal validity of this theorem? The issue is controversial. Seldom are mathematical discoveries the product of a single individual's genius. Often centuries and thousands of miles separate the appearance and the isolated reappearance of the same mathematical or scientific theory.

It is now acknowledged that the "Pascal Triangle" method of determining the coefficients of a binomial expansion was known in Sung China 300 years before Pascal was born, and that the root extraction algorithm credited to the 19th-century British mathematician W. G. Homer was employed by Han mathematicians of the 3rd century A.D. If, then, these mathematical processes are to bear the names of the persons who devised them, surely "Pascal" and "Homer" were Chinese. So too might such an argument be posed for the Pythagorean Theorem on the basis of evidence contained in ancient Chinese mathematics texts. It is the purpose of this monograph to present and examine this evidence.

This is a joint publication of the Penn State Press and the National Council of Teachers of Mathematics.

Excellent commentary! Well documented!
Format: Paperback, Format: Paperback
Michael Heiser can be trusted to provide clear explanations of the text, the context and some of the various opposing schools of thought concerning a host of Biblical issues. He provides excellent resources and asks questions to help the seeker to understand what Scripture REALLY says. Careful! Some of your denominational doctrines may need to be re-examined. But if that’s the case, isn’t “now” a better time than later? Be blessed on your journey 🙏

Okay
Format: Paperback
I was hoping for a modern day translation of the book of Enoch. This helps to understand it but still not an easy read for the average person.

Must have!
Color: Gold
Best Paper Towel Holder ever! Heavy enough that you can grab a paper towel with one hand without ‘holding’ the holder itself. The spray bottle is icing on the cake. Highly recommend!
