“To know is to possess, & any fact is possessed by everyone who knows it, whereas those who feel the truth are possessed, not possessors.”
— E.E. Cummings

[Gro-Tsen @gro_tsen]

Short version:

ⓐ progress in math ≡ progress in human understanding (NOT problem solving);

ⓑ such progress can only be brought by asking interesting questions;

ⓒ such questions can only be found by (human) learning a problem, thinking hard and ideally getting stuck;

…

… I wonder if there have been linguistic studies on how mathematicians choose their technical terms, and what makes them prefer certain words over others. This could be interesting.

I posted an answer (to an old question) on MathOverflow explaining how one can actually algorithmically compute the 27 lines on a cubic surface (by representing the lines through their Plücker coordinates): https://t.co/b8TSoh4CG8

"I don't believe in boundaries between different areas of mathematics. I like to think about challenging problems that I am excited about, and follow wherever they lead me." – Maryam Mirzakhani (1977–2017)

"The sentiment of mathematical elegance is nothing but the satisfaction due to some conformity between the solution we wish to discover and the necessities of our mind [...]" – Henri Poincaré (1854-1912)

@mezabarbarm Eu gosto do Israel, mas não consigo gostar desse livro dele... O Fulton até vai.

Em setembro de 2023, lançamos a Estratégia Nacional para o Desenvolvimento do Complexo Econômico-Industrial da Saúde. Com este programa, queremos fortalecer a indústria nacional de saúde e aumentar a produção nacional de itens prioritários no SUS.

A iniciativa é um dos carros-chefe da Nova Indústria Brasil, coordenada pelo companheiro e ministro do @MDICoficial, @geraldoalckmin.

O trabalho está dando resultados. O ministro @padilhando, do @minsaude, recebeu na última sexta (11) as primeiras unidades de insulina produzidas 100% no Brasil em 20 anos.

Quote of the Day

Serge Lang

"Axiomatization is what one does last, it's rubbish. It's the hygiene of mathematics, axiomatization."

[Quoted in D MacHale, "Comic Sections" (Dublin 1993)]

Quote of the Day #QOTD

Felix Klein (1849 - 1925)

"Thus, in a sense, mathematics has been most advanced by those who distinguished themselves by intuition rather than by rigorous proofs."

[Mark Chaplain @mcapellanus]

Quote of the Day

Max Planck (1858 - 1947)

"It is not the possession of truth, but the success which attends the seeking after it, that enriches the seeker and brings happiness to him."

[Arthur Newlands @ArthurNewlands]

@mcapellanus Only now I realised that John Conway died at the same day that Abraham Robinson. Surreal and hyperreal...

@Anthony_Bonato The machine simply ignored André Weil...

@SawtonKnuth @Anthony_Bonato “The woman” is Simone Weil!!
