"We believe that general relativity only works on large or 'macroscopic' scales, but that on very short distances, or microscopic scales, it must be replaced by a quantum theory of gravity which ...

The equation can be written as follows: 1/v^2 * ∂^2y/∂t^2= ∂^2y/∂x^2. In this equation, v is the velocity of a wave, and the other parts describe the displacement of the wave in one direction.

First among equals – James Clerk Maxwell. Earlier this year I asked readers to send me their shortlists of great equations. I also asked them to explain why their nominations belonged on the list and ...

Brian Greene: When we talk about vibration in physics, we have an interesting set of equations, mathematical equations that govern how a system vibrates. So if we have a string on a violin, we ...

One was along the lines of a list of named equations from Wikipedia (which has, at most, about 250 equations that aren’t even all related to physics). The researchers used 41 of those equations ...

While this seems obvious in our experienced reality, the underlying laws of physics do not inherently favour a single direction. Whether time moves forward or backwards, the equations remain the same.
