Avec près de 200 000 entrées en 15 jours, L'Agent secret est déjà le plus gros succès de Kleber Mendonça Filho en France, devant Aquarius (sorti en 2016). Félicitations et bonne année 2026 au cinéma brésilien ! 🇧🇷

The Fourier Transform is a mathematical operation that transforms a function of time (or space) into a function of frequency. In essence, it decomposes a complex signal into its constituent sinusoidal components, each with a specific frequency, amplitude, and phase. This is particularly useful in many fields such as signal processing, physics, and engineering, because it allows for the analysis of the frequency characteristics of signals. The Fourier Transform provides a bridge between the time domain and the frequency domain, enabling the analysis and manipulation of signals in ways that are more intuitive and computationally efficient. The result of applying a Fourier Transform is often represented as a spectrum, showing how much of each frequency is present in the original signal.

At 26, during the Reign of Terror in France, Jean-Baptiste Joseph Fourier narrowly avoided the guillotine. A decade later, he made a discovery that changed mathematics forever.

You're unlikely to discover something new without a lot of practice on old stuff.

I believe, the power of governments should be limited. Governments ought not to be empowered to decide the validity of scientific theories.

John von Neumann est né il y a pile 122 ans.
Mathématicien génial, il fréquenta entre autres Hilbert, Heisenberg, Dirac, Einstein, Bohr, Gödel, Oppenheimer, Fermi... En 1936, il publia un livre crucial : « La logique de la mécanique quantique ».
On lui doit cette phrase : « Si les gens pensent que les mathématiques ne sont pas simples, c’est uniquement parce qu’ils ne réalisent pas à quel point la vie est compliquée. »

On December 10, 1985, astronomer Carl Sagan testified before the United States Senate Committee on Environmental and Public Works regarding the potential impacts of the greenhouse effect. His testimony is widely cited for its early and clear warning that human activity was altering the global climate.

Le 26 décembre 1898, Pierre et Marie Curie annoncent devant l'Académie de Médecine qu'ils ont pu isoler un élément fortement radioactif jusque-là inconnu, baptisé “radium”. Découverte qui vaudra au couple Curie de se partager le prix Nobel de physique en 1903.

“We've arranged a society based on science and technology, in which nobody understands anything about science and technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces.”
