Odds? There are no odds.
Odds are division of probabilty and dividing by zero is not allowed.

**Descartes’ Mathematics**
“_In La Géométrie, Descartes details a groundbreaking program for geometrical problem-solving—what he refers to as a “geometrical calculus” (calcul géométrique)—that rests on a distinctive approach to the relationship between algebra and geometry._”

Ce genre de retour de collègue.
Vive le !

Je travaille le chapitre sur les variables aléatoires en terminale et il y a des vraies choses profondes derrière (les histoires de convergences etc., entre autre). Évidemment je n'aurai pas le temps de mentionner tout ça, mais ça fait plaisir de réfléchir de nouveau à ces notions.
J'espère que j'aurai la question « Pourquoi est-ce que la loi faible des grands nombres est appelée faible ? » pour éveiller les curiosités.
"De tous les scientifiques, les mathématiciens sont à coup sûr les plus attachés à leurs bibliothèques. C'est normal : d'une part, les écrits mathématiques sont souvent longs et difficiles à maîtriser, et d'autre part leur durée de vie est considérable. Dans quelle autre science trouve-t-on des articles qui peuvent atteindre plusieurs centaines de pages ? Et dans quelle autre science trouve-t-on des traités qui restent valables[...]"– Cédric Villani (1973-)

"Of all scientists, mathematicians are undoubtedly the most committed to their libraries. This is understandable: on the one hand, mathematical writings are often long and difficult to master, and on the other hand, their lifespan is considerable. In what other science do we find articles that can run to several hundred pages? And in what other science do we find treatises that remain valid for centuries, even millennia [...]" – Cédric Villani (1973-)

One of the best things I saw this week: a paper uncovering alien signals in the Riemann Zeta function. April Fools always brings peak creativity.
Question for the mathematicians and scientists out there. Anyone able to help me in working out what they have actually done here to calculate the "Mean Wind"? The data they used was obtained from the ERA5 dataset so comes in hourly values for U (east-west) and V (north-south) component.
#Math #Maths #Mathematics I get maths students coming to me in their last year of high school not having learnt the main reason we use radians rather than degrees
Essentially, calculus.
E.g. the derivative of a trig function where the variable is in radians, is simpler/cleaner than in degrees, for example:
If x is in radians then
d/dx (sin x) = cos x
In degrees:
d/dx (sin x) = (pi/180) cos x
The extra factor of (pi/180) makes things messy.
9 avril 1869 : #CeJourLà naissance de Élie Cartan (†6/5/1951), mathématicien français dont les travaux portent notamment sur les groupes et algèbres de Lie, la géom. différentielle, les équat. aux dérivées partielles. Il a introduit la notion de spineur.

Bonus #Joke 1:
I saw my math teacher with a piece of graph paper yesterday. I think he must be plotting something.
Bonus #Joke 2:
Did you hear about the over-educated circle?
It had 360°!
(It's #HootinTootinTuesday again! Post some jokes or funny memes under this hashtag today, and bring lots of smiles to #Mastodon.)
Years ago I recall the question of whether complex numbers vs real numbers gave #neuralnetworks a greater ability to learn ?
I don't recall the answer
does anyone know?

...Suddenly three became an infinity. Maths is often like this and I think it’s generally a hint that one is moving in the right direction.

I recall learning about the quaternions surprisingly early in life and becoming somewhat obsessed with them and other related algebras I managed to discover along the way all of which seemed to provide sensible finite numbers of solutions to various problems; then suddenly realising one day, some years later, that Hamilton had not only found three square roots of minus one but that *every point* on the unit imaginary sphere is a square root of minus one...
