Topology | Properties of topological spaces
In mathematics, a Rothberger space is a topological space that satisfies a certain a basic selection principle. A Rothberger space is a space in which for every sequence of open covers of the space there are sets such that the family covers the space. (Wikipedia).

We take a detour from the Angular Momentum Mind Map to cover the important topic of Tensor Product spaces in the Dirac Formalism. In quantum mechanics, the notion of tensors is hidden under the hood of the formalism and this lesson opens that hood. The goal is to make us confident that we

In computational topology and geometry, the Gromov-Hausdorff distance between metric spaces provides a theoretical framework to tackle the problem of shape recognition and comparison. However, the direct computation of the Gromov-Hausdorff distance between finite metric spaces is known to

Black holes are everywhere, including at the center of our galaxy. But because they’re invisible they’re quite difficult to study. Looking at the disks of material surrounding them, however, can give us tons of clues about how they function, how they form, and how accurate Einstein’s theor
