A cat co-authored a scientific paper in 1975, when his owner, a physicist named Jack H. Hetherington, decided to add him as a second author to avoid changing the plural pronouns in his manuscript. The cat’s name was Chester, and he was given the pen name F.D.C. Willard, which stood for Felix Domesticus, Chester. Willard was also the name of Chester’s father. The paper was about atomic behavior at different temperatures, and it was published in Physical Review Letters, a prestigious physics journal. Chester’s co-authorship was revealed when Hetherington sent some signed copies of the paper to his friends and colleagues, and included the cat’s paw prints as his signature. The story became widely known and amused many people in the scientific community. Chester even published another paper as the sole author in 1980, in a French popular science magazine. He died in 1982, but he is still remembered as the first and only cat to have authored a published scientific paper.

A jogger’s ponytail sways from side to side as the jogger runs, although the head only moves vertically. It turns out the vertical motion is unstable to lateral perturbations. More on why that's the case in today's paper: fermatslibrary.com/s/ponytai…

Ever heard somebody saying 'Our city can't change, we are not like Amsterdam!' Well, neither was #Amsterdam. It took bold choices and consistent -and ongoing- efforts. —Zeilstraat, Amsterdam in the 1970s

Take the alphabet and do the following conversion: A = 1 B = 2 C = 3 ... Z = 26 Words are sums of the corresponding letter values. The word PRIME is prime.

Happy 136th Birthday to Srinivasa Ramanujan, a self-taught Indian mathematical genius. He discovered nearly 4,000 theorems and equations, unique and groundbreaking. Some of his results were so advanced that they were not proven until decades after his death. Today, India celebrates National Mathematics Day to commemorate Ramanujan's birth anniversary.

This animation shows the irrationality of pi through the rotation of two rods, each with a constant but different speed. Despite the intricate patterns they create, the rotations never perfectly align, highlighting pi's infinite, non-repeating decimal nature. This emphasizes the impossibility of expressing pi as a ratio of two integers, a key characteristic of irrational numbers. The perpetual near-miss between the rotations of the inner and outer rods, evident at moments like 22/7 and 355/113, well-known approximations of pi, further emphasizes the fascinating and unattainable nature of expressing pi as a simple fraction. This visual representation contributes to the richness of mathematical exploration, showcasing the captivating complexity of pi's irrationality.

Born #Today in 1914, Hedy Lamarr was one of the most prominent actresses of the Hollywood's Golden Age: what we generally ignore is that she was a scientist and co-inventor of the spread spectrum technology

A counter-intuitive mathematical fact is the existence of Intransitive Dice. A set of 3 dice (A,B,C) is intransitive if A normally beats B, B normally beats C, but A does not normally beat C. Here's an example: - Die A has sides 2, 2, 4, 4, 9, 9. - Die B has sides 1, 1, 6, 6, 8, 8. - Die C has sides 3, 3, 5, 5, 7, 7. The probability that A rolls a higher number than B, the probability that B rolls higher than C, and the probability that C rolls higher than A are all 5/9, so this set of dice is intransitive.
