One can derive the Lorentz transformations without specific using the second postulate of relativity. You can find it in this document: Transformations between inertial systems of reference. Ok it is still a draft:) Hope you enjoy it! Advertisements
The main question here is: given a matrix then what is ? Given is the matrix (1) . . . . It is clear that This can be written as . Note that and . We shall write and . … Continue reading
Recently experiment has shown that neutrinos move faster then light. Some claim that “neutrinos might break one of the most fundamental laws of physics”. The question would be “what law of physics would be broken?” In general this all is … Continue reading
Let us consider a medium and an observer that is moving through that medium. Say that the magnitude of the velocity of light with respect to the medium is and say that the velocity of the observer with respect to … Continue reading
In this post I will write something about the spontaneous creation of matter and antimatter. Let us consider matter as an elementairy particle. This elemenrairty particle has some mass and several quantumnumbers. We assume that charge itself is also a … Continue reading
Given is a body that has a constant acceleration. Let the acceleration be . Let us assume that the body starts at rest. If so then the travelled distance is given by and the velocity is given by . So … Continue reading
Consider a body that has a constant acceleration. Does body exceeds the speed of light? Let the constant acceleration be . Assume that body starts at rest, then the travelled distance is given by and . So the critical time … Continue reading
What are inertial systems of reference? Why are transformations between inertial systems of reference linear? A simple analysis of transformations between systems of reference. We have two systems of reference, denoted by and . Each system has his own coordinates; … Continue reading
Consider a body with mass that is accelerated using a constant force acting on the body. Let the body start at rest, such that the momentum for . The force is given by . So if the force is constant, … Continue reading
