On the parallel postulate
... The famous French Empereror Naepoliean Bonaparte used to tell time and again: The word impossible must be taken away from dictionary. In this paper, the author proved Nepolian’s quotation by obtaining a result for the parallel postulate. But there are many geometrical battles which are to be won. I ...

The effective mass tensor in the General Relativity
... In the metric (3) the EMT components depend on the metric tensor components. It is a very interesting result, what can suggest that this EMT in GR exist (9). We would like to postulate a new version of the Mach's Principle in the sound: the effective mass is a result of interaction between the body ...

Homework 1 Solutions
... We can see that from the above equations we cannot solve for Ȧ0 . The reason is that there is no term in the Lagrangian with time derivative of A0 . In other words, A0 is not a dynamical field. Solution to Exercise 2.5 Now, if we fix the gauge by choosing A0 = 0, and treat Ai as dynamical fields, w ...
