"Suddenly, an inner voice speaks to me and [...] give me orders: "just add terms and employ the Poisson formula". The invisible protagonist disappears from the scene, leaving me all the work. Wondrous miracle, I see the bridge of light and the work is easy to do. I am enchanted. The result becomes a logical consequence of another fact I knew, and in a blitz, I can annex a small part of mathematics to "my world" [...]" – Michèle Vergne (1943–)

Photographic portrait of Michèle Vergne, and a quote : "Suddenly, an inner voice speaks to me and [...] give me orders: "just add terms and employ the Poisson formula". The invisible protagonist disappears from the scene, leaving me all the work. Wondrous miracle, I see the bridge of light and the work is easy to do. I am enchanted. The result becomes a logical consequence of another fact I knew, and in a blitz, I can annex a small part of mathematics to "my world". But soon, this fleeting feeling of satisfaction disappears and I realize that there are more profound cases that my insights are unable to explain."

I joked this morning about needing a three sided die. I dismissed it as being ridiculous, hence the joke, but now I'm wondering if there's any kind of funky, conceptual, nonEuclidean space where that would be possible.

Comprehensive presentation of the "Theorem of the Day", starting with a statement of this theorem.

Kuratowski’s Theorem : A graph G is planar if and only if it contains neither K5 nor K3,3 as a topological minor.

Break out the calculators: November 23 is Fibonacci Sequence Day

The cornerstone of modern math wouldn’t be possible without the Hindu-Arabic numerical system.

A page of Fibonacci's Liber Abaci from the Biblioteca Nazionale di Firenze showing (in box on right) 13 entries of the Fibonacci sequence: the indices from present to XII (months) as Latin ordinals and Roman numerals and the numbers (of rabbit pairs) as Hindu-Arabic numerals starting with 1, 2, 3, 5 and ending with 377.

My first, favorite and most important sequence, the weights of prime numbers: A117078
We see prime numbers classified by level and by weight on the graph.

A117078: a(n) is the smallest k such that prime(n+1) = prime(n) + (prime(n) mod k), or 0 if no such k exists ➡️ https://oeis.org/A117078
