Physics is a science that is essentially based on measurement and modeling. The physicist’s background must therefore contain the tools and methods that allow him to: derive rational information from his measurements. approach the behavior of a model system using … Read More
Amazon has announced a bold step towards sustainability with a major investment in small modular reactors (SMRs) to use clean nuclear power globally. The initiative marks a significant shift in the company’s energy strategy as it aims to reduce its … Read More
In a sensational announcement on October 18, 2024, geophysicists from the Technical University of Denmark and the German Research Center for Geosciences reported that there are signs that Earth is on the verge of a significant magnetic field reversal. This … Read More
”There is, however, one case where I will have to take your indications into account and modify my measurements. It is when it is a question of constructing an integral mathematical representation of the universe, I mean of everything that … Read More
Top antitop quark event “Spooky action” is a famous phrase coined by Albert Einstein to express his discomfort with quantum entanglement. Quantum entanglement is a phenomenon in quantum mechanics in which two or more particles become bound so that their … Read More
Isaac Newton’s mechanics is based on a theology: his God is a geometer and an architect who has known how to combine the materials of the system in such a way that result a stable state of equilibrium and a … Read More
The originality of the Milesians seems to have been the choice of images by which they represented the sky and the meteors; these images retain nothing fantastic from the myths; they are borrowed either from the arts or from direct … Read More
Definitions Scalar field: application which associates a scalar (i.e. a number) with each point in space. Vector field: application which associates a vector with each point in space. Edges of volumes and surfaces: for a volume V, we note ∂V … Read More
Let us indicate, in its essential features, the change of mind produced by the prodigious success and by the diffusion of Newton’s celestial mechanics: at the beginning of the 18th century, a sort of Cartesian orthodoxy reigned almost everywhere in … Read More
Now I must add that I consider these changes beneficial. Let us indeed leave ponderable matter behind. What would my situation be with regard to light, and more generally electromagnetic facts, if my dimensions of space and time had remained … Read More
Figure 1.1 This image might be showing any number of things. It might be a whirlpool in a tank of water or perhaps a collage of paint and shiny beads done for art class. Without knowing the size of the … Read More
We have just looked for how light could have the same speed for the fixed observer and for the moving observer: the deepening of this point revealed to us that a system S’, resulting from the splitting of a system … Read More
