Civilisation DID not start in the West.

That was the statement that brought the wrath of the racists from the Portuguese middle class to join the foray initiated by the bichas that have been stalking me since last century, telling lies that I work at night clubs among other obscenities. 
The first stalking fucker I tested was a middle-aged one who feigned selling me a life insurance in Portugália, in Cascais, around 1997-1998. He failed the test when I answered negatively about my mother's French-derived middle name.

The second statement was made on this blog and in various forums in which the fuckers stalk me over, that I am an African, NOT a Nigger/Preto, to which the stupids have been equated to the binary "black (nigger)/white", as a racist health worker alluded to in the Santa Maria hospital.

You cannot understand me. We do not share values.

😂😂😂
Why would people I never fucked care about my sex drive, my penis or my sexual orientation?
They either fuck your ass or you are a sycophant to believe them!

'Cause Imperialism!

Hints of Trigonometry on a 3,700-Year-Old Babylonian Tablet

Hints of Trigonometry on a 3,700-Year-Old Babylonian Tablet by Kenneth Chang for the NYTimes (AUG. 29, 2017)

Suppose that a ramp leading to the top of a ziggurat wall is 56 cubits long, and the vertical height of the ziggurat is 45 cubits. What is the distance x from the outside base of the ramp to the point directly below the top? (Ziggurats were terraced pyramids built in the ancient Middle East; a cubit is a length of measure equal to about 18 inches or 44 centimeters.)

Could the Babylonians who lived in what is now Iraq more than 3,700 years ago solve a word problem like this?

Two Australian mathematicians assert that an ancient clay tablet was a tool for working out trigonometry problems, possibly adding to the many techniques that Babylonian mathematicians had mastered.

“It’s a trigonometric table, which is 3,000 years ahead of its time,” said Daniel F. Mansfield of the University of New South Wales. Dr. Mansfield and his colleague Norman J. Wildberger reported their findings last week in the journal Historia Mathematica.


…

The other three columns are much more intriguing. In the 1940s, Otto E. Neugebauer and Abraham J. Sachs, mathematics historians, pointed out that the other three columns were essentially Pythagorean triples — sets of integers, or whole numbers, that satisfy the equation a2 + b2 = c2.

This equation also represents a fundamental property of right triangles — that the square of the longest side, or hypotenuse, is the sum of the squares of the other two shorter sides.

That by itself was remarkable given that the Greek mathematician Pythagoras, for whom the triples were named, would not be born for another thousand years.

Why the Babylonians compiled the triples and wrote them down has remained a matter of debate. One interpretation was that it helped teachers generate and check problems for students.

Deconstructing Sound || Mike The Monkey @ HalfRez 2015

Mike The Monkey HalfRez 2015: Deconstructing Sound from Greyscalegorilla on Vimeo.

Mike Senften joined us at HalfRez this year to blow everybody's mind once again. Animators, musicians, engineers, doctors, stock traders and countless other professions rely on waveforms to describe the behavior of data over time. In this presentation Mike shares a visual approach to understanding the construction and deconstruction of waveforms. It's a short and sweet introduction to basic trigonometry as well as Fourier Synthesis and Fourier Analysis (which were first developed over 200 years ago by French mathematician Joseph Fourier. It requires little to no prior experience in mathematics, but a passion for nerdery and a glass of bourbon are always helpful.
