It’s high time to support my physics by computers. Today I experimented with Newton’s Law of Gravitation for 3D and as far as it goes to one object it works great. However I didn’t managed to apply the force to the second object (The Sun).The movie which you can see above is a gif, cause [...]

Well, everyone of us probably heard in high school (or earlier) that the photon has it’s own momentum.
And I think that more then a half of us kept wondering then about it. Namely, without deep knowledge of Physics, such statements like “light have no rest mass”, or “light is an electromagnetic wave, but it has [...]

Superposition is such an obvious rule in Physics that it’s worth telling when it doesn’t work. The rule breaks, when equatation of a wave is not longer linear. It happens when the altitudes are big enough to make the Hook’s Law fail ( ). Example: Shock waves after explosions which characteristic differs from a [...]
