As given by Britain’s brilliant, opinionated Sir Arthur Stanley Eddington, the seven fundamental constants of Nature are: e, the charge of an electron; m, the mass of an electron (at rest); M, the ...

In physics, there are a host of standard constants: the speed of light, the charge-to-mass ratio of the proton, and Planck's constant, to name just a few. Repeated measurements going back a few ...

The laws of physics are constant and unchanging . . . or are they? Researchers are beginning to find tantalising evidence that the physical constants of science might not be as absolute as we thought.

Some things never change. Physicists call them the constants of nature. Such quantities as the velocity of light, c, Newton's constant of gravitation, G, and the mass of the electron, m e, are assumed ...

The constant — the ratio of the mass of a proton to the mass of an electron — has changed by only one hundred thousandth of a percent or less over the past 7 billion years, the observations show. The ...

One of the most dissatisfying aspects of modern physics is the fundamental constants. It’s not that they are constant that bothers anyone, it is their very existence that is offensive to ...

In a new study, scientists show that two fundamental physical constants govern how runny a liquid can be. Their equation relates the minimal value of elementary viscosity (the product of viscosity and ...

An ultraprecise new measurement has given some weird particle physics theories a black eye. By measuring one of nature’s most fundamental constants more precisely than before, scientists have tested ...

Physics is based on the assumption that certain fundamental features of nature are constant. Some constants are considered to be more fundamental than others, including the velocity of light c and the ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Robyn Williams: The point about constants in science is that they're supposed to stay, well, constant.
