Planck’s constant is one of the most important numbers in all of physics. It is, essentially, the ultimate guide to the quantum world. It tells us where quantum effects are important, the fundamental ...

If you divide the matter in the Universe into smaller and smaller constituents, you'll eventually reach a limit when you hit a fundamental, indivisible particle. All macroscopic objects can be divided ...

Using a state-of-the-art device for measuring mass, researchers have made their most precise determination yet of Planck's constant, an important value in science that will help to redefine the ...

General relativity, Einstein’s theory of gravity, gives us a useful basis for mathematically modeling the large scale universe – while quantum theory gives us a useful basis for modeling sub-atomic ...

Researchers at the National Institute of Standards and Technology (NIST) have made their most precise determination yet of Planck’s constant. This will let NIST redefine the kilogram, the official ...

1.616*10^-35 metres. That's so small. If atoms (~ 10^-15 metres) were planck length diameter, packed in next to each other in an array at planck length distances, and there wasn't any pesky forces and ...
