Properties of topological spaces
In mathematics, a topological space is said to be ultraconnected if no two nonempty closed sets are disjoint. Equivalently, a space is ultraconnected if and only if the closures of two distinct points always have non trivial intersection. Hence, no T1 space with more than one point is ultraconnected. (Wikipedia).
If the universe is spatially infinite, what can we say about reality...

Hidden Dimensions: Exploring Hyperspace
Extra dimensions of space—the idea that we are immersed in hyperspace—may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still--but ultimately hit a dead end. Modern

Wendy Freedman - What would Multiple Universes Mean?
Is there more than one universe? According to current cosmology, our entire gigantic universe is only one of innumerable universes, each universe like one tiny bubble in a limitless ocean of universes. It's called a 'multiverse' and it radically expands the size of reality. Click here to

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
