Dears,
In the film the Arrival, of Denis Villeneuve, the alien ship apparently subjugates the terrestrial gravity. It's one thing to simulate gravity in space, another thing would be to simulate a gravitational system apart on Earth. Is there at least a theoretical possibility for this? How...
I wonder what really motivated Einstein to formulate his general theory of relativity:
a) would be due to the principle of equivalence?
b) it would be because after the relativistic formulation of Maxwell's equations, there was only the classical gravitation with the factor 1 / r ^ 2?
c) would...
Is correct to say that two vectors , three vectors or n vectors as a common point of origin form a tensor ? What is the correct geometric representation of a tensor ?
The doubt arises from the fact that in books on the subject , in general there is no geometric representation.
Sometimes appears...
Kk, thank you... but I even searched for books, and I think the following book is a good suggestion for consultation:
Einstein's Theory: A Rigorous Introduction for the Mathematically Untrained
by Øyvind Grøn, Arne Næss
few authors solve exercises related to Christoffel Symbols ... I think...
Friends,
I wish indicate to me a textbook that teaches you calculate in detail the symbol of Christoffel (undergraduate or graduate level in physics).
Thank You for your help!
