3,700-year-old Babylonian stone tablet gets translated, changes history
They were doing trigonometry 1500 years before the Greeks.

I think the claim of this article is debatable. There are Pythagorean triples (a^2+b^2=c^2, with a,b,c integers), solutions of quadratic equations (cf. the quadratic formula), and trigonometric tables. The Wikipedia entry for Plimpton 322 states that researchers are unsure as to which of these three is inscribed into the artifact.![]()

I think that although Pythagorean triples, and implicitly, quadratic equations, are built into the notion of trigonometric expressions, such as the formula for the chord of a circle, trigonometry proper is marked by tying triangles (e.g. the Pythagorean theorem) to circular forms (like the unit circle, and where angles come into play). The burden of proof is on the researchers mentioned in the article to show that the Pythagorean triples on Plimpton 322 in fact describe circular forms in the manner of a veritable trigonometric tables such as has been ascribed to the works of Hipparchus from ancient Greece.
Nevertheless, the Babylonians were certainly pioneers in mathematics.
For me, it's that I'm gonna choose 1287 as my thrice-weekly Powerball pick through the end of the year.Now I’m intrigued with this sequence, what’s the significance?

That is from an early attempt of mine to solve a discrete mathematics and combinatorics problem that I thought about several years ago in connection with an advertisement I heard. I still have my notes on it.Now I’m intrigued with this sequence, what’s the significance?

Be sure to add: "MUCH smarter than Dairy Queen (and their marketing partner)" to your resume.That is from an early attempt of mine to solve a discrete mathematics and combinatorics problem that I thought about several years ago in connection with an advertisement I heard. I still have my notes on it.
Circa 2010 in Canada, there was a Dairy Queen commercial that said you can have pairs, triples, or quadruples from a choice of nine items. The claim was this number exceeded 20,000 possibilities. I thought this to be a gross overestimate and tried to come up with a systematic way of tallying the actual numbers in the sequence. ...
In short, the Dairy Queen commercial was far off, and that was false advertising. 45+165+495=705. This is far shy of "over 20,000 possibilities".
