Heisenberg’s uncertainty principle is famous in quantum mechanics. However, it doesn’t have its roots in quantum mechanics. Let’s look at Fourier transform pairs. Continue reading Heisenberg’s uncertainty principle

We will focus on a few simple problems where we will manipulate Einstein’s equations for relativistic energy and momentum. Continue reading Simple problems on relativistic energy and momentum

We will focus on a couple of simple problems where we will manipulate the equations for relativistic energy en momentum. Continue reading Simple problems on relativistic energy and momentum
