## Spatial geometry, Minkowski space

Today I want to talk to you again about the importance of spatial geometry since this is what tells us how our universe is mounted, therefore how it works and […]

Surely this question you have never done and it is that we assume that it is natural for the Earth to rotate on its own axis since our planet does […]

Yesterday, if you remember, I told you that it was the tangential (unitary) vector to a curve or path, so today I will tell you how to calculate and that […]

As I want you to learn a bit of differential geometry, which is not as complicated as they are painted or how it sounds and since I imagine that you […]

Many times, I think, you have read me talk about differential geometry without, at bottom, understand what the heck I’m talking about, so the time has come to explain a […]

Today I want to talk about something that I tell you a lot, imagining that, you know what I mean: geometry. Normally I assume that this basic part of mathematics […]
