The next day I received a very short reply from the academician: dS ~ – ds. This is the whole answer. There was nothing else.
I formulated the problem of maximum own time for different scientists. Nobody answered me. Most of them could not enter the subject at all.
When I came to the conclusion that time in a gravitational field (near the Earth) does not slow down, but, on the contrary, accelerates, contrary to the numerous assurances of […]
So, according to Fermat’s principle (it underlies the principle of least action), any object, including a clock, moves in the gravitational field from one point to another so as to […]
We have found out the physical meaning of the wave equation and now we can use it to solve some problem, for example, the movement of the body in the […]
Let’s look at the wave equation (up). It can be written in two forms: through the wavelength (top) and through the period (below). In a sense, the upper equation is […]
So, from the most general considerations, we strictly deduced the equation of wave motion. In my opinion, this equation is very beautiful, because it is simple and fundamental.
Consider the motion of a wave. It can be light, an electronic wave, a wave on water, a sound wave. In general, any wave, though classical, even quantum. So I […]
After Einstein’s creation of the general theory of relativity, it became clear that time in different points of space can flow at different speeds because of the influence of gravity. […]
When the light moves from point A to point B, it chooses the path that requires the least time. It seems that the light “appreciates” its time.
