What is the Geometric Meaning of the Four-Vector in Special Relativity?

In summary, the four-vector in special relativity is a mathematical tool used to describe the position and motion of an object in four-dimensional spacetime. It is composed of four components: three spatial components representing the object's coordinates in space, and one temporal component representing its coordinate in time. The four-vector allows for a geometric interpretation of the principles of special relativity, including time dilation and length contraction. It is a fundamental concept in understanding the effects of relative motion and frames of reference in Einstein's theory of relativity.

Hi there,

I am Stefan, I am just starting my third semester of physics at Technische Universität Berlin Germany.

If started my studies after working nearly 20 years in information technology.

My main interest is the Special Theory of Relativity. Especially, the geometric meaning of the four-vector.

I am looking forward to finding some like minded people here.

Greetings
Stefan
