Dans leur ouvrage Balade sous la pluie, paru en 2025 aux Presses des Ponts, Auguste Gires, ingénieur en chef du corps des Ponts, eaux et forêts, et chercheur au laboratoire Hydrologie, météorologie et complexité de l’École nationale des ponts et…
Researchers have developed a new kind of nanoelectronic device that could dramatically cut the energy consumed by artificial intelligence hardware by mimicking the human brain. The researchers, led by the University of Cambridge, developed a form of hafnium oxide…
by S & T • • Commentaires fermés sur Is time a fundamental part of reality? A quiet revolution in physics suggests not
Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and we die, in exactly that order.…
by S & T • • Commentaires fermés sur Information could be a fundamental part of the universe – and may explain dark energy and dark matter
For more than a century, physics has been built on two great theories. Einstein’s general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles and fields. Both work brilliantly in their…
by S & T • • Commentaires fermés sur What, exactly, is space-time?
Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time — the interwoven fabric of space and time at the heart of Albert Einstein’s theory of relativity. Space-time is frequently described as the “fabric of…

Earth will complete a rotation 1.33 milliseconds earlier than usual on Tuesday, August 5. That makes it one of the shortest days of 2025 at 86,399.99867 seconds long. How that happens, and how we can even measure it with…

La interacción fuerte es la responsable de la estabilidad de la materia. O sea, de que nosotros mismos, con todo lo que nos rodea, no nos desintegremos. Hablamos de la más intensa de las cuatro interacciones fundamentales de la naturaleza.…

Puisque l’Univers est en expansion, cela veut-il dire qu’il est parti d’un point précis, où il aurait été tout contracté ? Eh bien non ! Un physicien nous explique. Il y a environ un siècle, les scientifiques s’efforçaient de concilier ce qui…

Back in high school chemistry, I remember waiting with my bench partner for crystals to form on our stick in the cup of blue solution. Other groups around us jumped with joy when their crystals formed, but my group just…

European researchers are developing quantum computers using light and glass, in a collaboration that promises breakthroughs in computing power, battery technology and scientific discovery. Giulia Acconcia grew up in the picturesque, historic town of Spoleto, nestled in the foothills of…
