A newly discovered class of materials known as “topological insulators” could help physicists to obtain new ways of defining the three basic physical constants – the speed of light (c); the charge of ...

When we think about our Universe at a fundamental level, we think about all the particles in it and all the forces and interactions that occur between them. If you can describe those forces, ...

Redefinition of the kilogram will not make the kilogram more precise, but it will make it more stable. A physical object can lose or gain atoms over time, or be destroyed, but constants remain the ...

(PARIS) — Scientists from 60 countries voted in a historic event in Versailles, France on Friday to change the definition of the kilogram, basing it on electric currents rather than a single solid ...

Scientists have performed the most accurate measurement yet of the Boltzmann constant. While the impact of such an achievement is not immediately obvious, the measurement could revolutionize the way ...
