David Hilbert knew that every smooth cubic surface — a twisty shape defined by third-degree polynomials — contains exactly 27 straight lines. Hilbert used those lines to construct a simple formula for the roots of any 9th degree polynomial in one variable. https://t.co/J7YYWsLftnpic.twitter.com/jwrczOKuAO
Le saviez-vous ? En Nouvelle-France, on prononçait «moé» et «toé» et non pas «moa» et «toa». C’était réellement la bonne façon de prononcer ces mots-là en français. Les lettres «oi» devaient se prononcer «oe». Ainsi, les mots «soir», «Roy» se prononçaient «soair», «roet». pic.twitter.com/hWIvyqlOxX
Before the 18th century it was common to use vincula (straight lines drawn above the operations) to indicate order of operations instead of parentheses. pic.twitter.com/GcdK4igaZA
