Maybe throw a lot of water, like 10 time its mass to it? Continue reading “Throwing water to the Sun”

Inertial Frames in General Relativity

Today I don’t want to talk about code, but about one of my other passions: Physics…I want to start this new thread with something relative basic: the concept of inertial frame of reference. In physics courses the importance of such concept is often underestimated by teachers. The concept of inertial frames is not only important in Newtonian Mechanics, but even more important in Einstein relativity. Continue reading “Inertial Frames in General Relativity”
