When the first #mathematician answers “I don't know,” the other two deduce that he wants a #beer, because if he didn't want one, he could have answered ‘no’ (on the other hand, he couldn't answer “yes,” since he didn't know what the other two wanted). When the second mathematician answers, the third concludes that his two colleagues want a beer and can therefore answer yes for everyone.

#OnThisDay Birth Anniversary of #English #Writer Charles Dickens (1812) - regarded by many as the greatest #Novelist of the Victorian era.
Birth Anniversary of #English #Mathematician G. H. Hardy (1877) - mentor of the Indian mathematician Srinivasa Ramanujan.
Happy Birthday Tawakkol Karman (1979) - co-recipient of the 2011 Nobel Peace Prize, becoming the first Yemeni, the first Arab woman to win a #NobelPrize.

The pronunciation of the names of Greek letters by native English speakers seems to be a matter of taste 🙂
In Britain, ϕ is normally 'fye' and π is 'pie', but linguistically I suspect that 'fee' and 'pee' make more sense.
Also, why do Americans pronounce β and ζ as 'bayda' and 'zayda'?!
Also, also, I believe Germans tend to pronounce ζ (et al) with a short 'e' sound (which feels kind of sensible) - i.e. 'zetta'.
What we need is a proper Greek #mathematician to tell us all how say them!
#BlackHistoryMonth is a great time to celebrate mathematician and NASA scientist Katherine Johnson (née Coleman; 1918 – 2020). One of the first Black women employed as a NASA scientist (and its predecessor NACA), she was known for her mastery of complex manual calculations of orbital mechanics and played a pivotal role in the success of the US crewed spaceflights from the beginning.🧵

For #PrinterSolstice2526 prompt expression: my #linocut of Olga Ladyzhenskaya (1922-2004), a #mathematician who overcame personal tragedy, faced Soviet totalitarianism & the catastrophic political upheaval of the 20th century to make a huge impact on the math, making important contributions to study of partial differential equations (PDEs). She changed the way PDEs are examined & popularized the 🧵

The next #PrinterSolstice2526 prompt is expression so I am working on a portrait of one of the great 20th century mathematicians, Olga Ladyzhenskaya (1922-2004). She made immense contributions to the study of partial differential equations, particularly with the Navier-Stokes equations and fluid dynamics and she was brave and kind in her personal life, 🧵

Happy birthday to #mathematician David Hilbert (1862-1943)! This linocut print illustrates the paradox of Hilbert’s Grand Hotel, a thought experiment conceived by Hilbert in 1924 to show the paradox of infinite sets. If you imagine a regular hotel with a finite number of rooms, if they are all filled you can’t add more guests. In an imaginary infinite hotel however, guests are always welcome! Even if all the (conveniently numbered 1, 2, 3, ...) rooms are filled, 🧵
#OnThisDay Birth Anniversary of #Economist W. Arthur Lewis (1915) - famous for his contributions to development economics. He won the Nobel Memorial Prize in Economic Sciences in 1979.
Birth Anniversary of #Mathematician David Hilbert (1862) - known as one of the founders of proof theory and mathematical logic.

This advance is a radical and exciting departure from the current method, counting on my fingers and toes.

(For those unfamiliar, #Bayes was an 18th c. British #mathematician who developed an equation that has been used for centuries to calculate the probability of an event given what we already know. For example: if you get a medical test with 80% accuracy, and it returns positive, what is the chance you actually have the tested condition? Not 80%, as you may assume. The answer depends on the likelihood of developing that condition in the first place, and then applying the likelihood that the test is correct. Bayes’ theorem is pervasive in #medicine and many other disciplines, and not recently discovered by nut job RFK Jr. and his empty-headed lackeys.)
Happy birthday to Russian #mathematician & writer Sofia Vasilyevna Kovalevski (1850-1891). Her contributions to analysis, differential equations & mechanics include Cauchy-Kovalevski theorem & the famed Kovalevski top. She was 1st woman appointed to full prof in N Europe or to serve as editor of a major sci journal. She is also remembered for her contributions to Russian literature. All of this despite living when women were 🧵
I just learned that the #mathematician Gauss figured out a formula to calculate the day of the week from a numeric date.

famous #mathematician, Theon Alexandricus (ca. 335–405), with whom she worked and published edited versions of Classical texts in mathematics. She also pursued her education in Athens and Italy before returning to Alexandria.⠀
⠀
It is difficult to precisely specify her own contributions to mathematics, since many documents have been lost (the Library of Alexandria itself was destroyed) and it was the tradition of the time to write commentaries on the great texts of Classical mathematics.🧵2/
Happy birthday to #mathematician & #astronomer Nicole-Reine Lepaute (1723-1788)! My #linocut celebrates her calculated path of the solar eclipse of 1764. She also worked with Alexis Clairaut & Jérôme Lalande to precisely calculate the date of return of Halley’s Comet, solving the notorious 3-body by hand (including the gravitational pull of Jupiter & Saturn on orbit). They worked in parallel, calculating for 6 months straight, barely stopping to eat!🧵
