Ben Krause, Hamed Mousavi, Joni Teräiväinen, and I have just uploaded to the arXiv our paper Quantitative bounds for sets lacking polynomial progressions with shifted prime difference. The purpose of this paper is to obtain quantitative ve…
In everyday European discourse there are only a small number of scientists whose names are widely known within the general populus–Copernicus, Galileo, Descartes, Newton, Darwin, Einstein, Curie–and even then the people only know very vagu…
This looks like a Rubik's Cube, but it's not: It seems that an open-cab truck filled to the brim with Rubik's Cubes hit a bump in the road, causing some of the cubes to spill out of the truck bed and onto the roadway. When, mere moments la…
Double Maths First Thing gets its kicks on a.19792ish Hello! My name is Colin and I am a mathematician on a mission to spread the joy and love in doing maths, figuring stuff out, getting stuck and getting unstuck again. You'll need to forg…
In recent months there has been a proliferation of AI-generated proofs of various old and new results, some of which have been formalized in the proof assistant language Lean. However, checking that a given Lean repository actually proves …
Ces cahiers proposent, pour chaque niveau, une sélection organisée d'exercices d'automatismes tirés de la plateforme MathALÉA. Chaque exercice est associé à un QR code : sur cette version num...
In this series of posts, we'll be featuring mathematical video and streaming channels from all over the internet, by speaking to the creators of the channel and asking them about what they do. We spoke to Ellie Sleightholm about her YouTub…
In the last post in this series, I talked about the rapid expansion in the availability and use of mathematical and scientific instruments in England in the Early Modern Period. After describing the areas where these new instruments came …
This post concerns the following conjecture of Sendov, as well as its strengthening by Phelps–Rodriguez: Conjecture 1 (Sendov's conjecture) Let , and let be a degree polynomial with all zeroes in the unit disk. Then for every zero of , the…
L'entrée en prépa scientifique, CPGE ou prépa intégrée, constitue un véritable changement de rythme et de méthode. Or, les différences entre les lycées d'origine peuvent être importantes : certains élèves ont déjà été un tant soit peu fami…
Double Maths First Thing has an army of clones Hello! My name is Colin and I am a mathematician on a mission to spread the joy and delight of working things out. I had a delightful chat with young Bill about complex numbers and matrices an…
A function of one variable can be translated in space by a spatial shift to obtain a new function and also modulated in frequency by a frequency shift to obtain a new function One can compose these two operations to obtain a time-frequency…
