"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.

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 ...

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 ...

We can only go out and measure their values and then insert those values into our equations to make physics work. All told, there are about two dozen such numbers.

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.
