3,700-year-old Babylonian tablet
#1
This is Interesting I Think,,, it'll upset some Greeks I think. But Who Really Cares??? 
Quote:3,700-year-old Babylonian tablet rewrites the history of maths - and shows the Greeks did not develop trigonometry
This little tablet is what has caused them to change their way of thinking.

Quote:A3,700-year-old clay tablet has proven that the Babyloniansdeveloped trigonometry 1,500 years before the Greeks and were using a sophisticated method of mathematics which could change how we calculate today.

The tablet, known as Plimpton 332, was discovered in the early 1900s in Southern Iraq by the American archaeologist and diplomat Edgar
Banks, who was the inspiration for Indiana Jones.


The true meaning of the tablet has eluded experts until now but new research by the University of New South Wales, Australia, has shown it is the world’s oldest and most accurate trigonometric table, which was probably used by ancient architects to construct temples, palaces and canals.


However unlike today’s trigonometry, Babylonian mathematics used a base 60, or sexagesimal system, rather than the 10 which is used today. Because 60 is far easier to divide by three, experts studying the tablet, found that the calculations are far more accurate.
Quote:“Our research reveals that Plimpton 322 describes the shapes of right-angle triangles using a novel kind of trigonometry based on ratios, not angles and circles,” said Dr Daniel Mansfield of the School of Mathematics and Statistics in the UNSW Faculty of Science.

“It is a fascinating mathematical work that demonstrates undoubted genius. The tablet not only contains the world’s oldest trigonometric table; it is also the only completely accurate trigonometric table, because of the very different Babylonian approach to arithmetic and geometry.

I found it interesting that > Tesla also Divide By Three's.

The guest speaker on Open Minds, which airs on GAIA t.v., was talking about this last night.

Don't expect me to learn a new math system, it scrambles my brain even thinking about it.   tinylaughing

First let me say that I hardly ever dare to approach math unarmed... armed with a calculator, that is. Although in the 6th grade I confused the heck out of my math teacher by coming up with my own way to do a specific type of problem instead of the "sanctioned" formula she gave us. It just didn't make sense her way, but I figured out a way that DID make sense to me. She even changed the numbers and she did the calculations her way, I did it my way, and I got it right every time.

I don't even know what kind of math it was, lol! I wonder though, if the calculations with the 60-based system are more precise than the accepted 10-based system, if maybe I just hunted another number and used a different ratio like the above article mentions. Dang, maybe I was actually smart back then... Lord how times have changed!!!

*Edit: I also failed the quizzes, even though my answers were right. I was supposed to show I could use the "official" way of thinking, not actually learn how to get the right answer!

That's just wrong! tinyok

Just like today, "they" want to brainwash the youth into thinking history is how they say... period!  They don't want anyone thinking for themselves, even when they are teaching lies.
