LOG#233. Electron microscopes.

Surprise! Second post today. It is a nice post, I believe. Usually, we see the world using photons in certain wavelengths. Our eyes can see only a very limited width of the electromagnetic spectrum. The quantum revolution taught us that … Continue reading

LOG#224. Vis tenebris.

What is dark energy? Where does it come from? Is it constant? Is it a quantum field? Is it vacuum energy? Nobody knows what is the 70% of the Universe! In the beginning of Physics as Science, Aristotle himself introduced … Continue reading

LOG#217. The 2 pillars.

Time of Cosmic Voyages https://www.youtube.com/watch?v=xEdpSgz8KU4 This is a long post, despite not being a special post (remember I make one of those every 50 posts). What are we going to see here? A five part post! Part(I). A descriptive prelude. … Continue reading

LOG#183. Bohrlogy: some pocket formulae.

This post continues the Bohrlogy thread I did some time ago. It aims to parallel electric Bohr (atom), the gravitational Bohr atom and the black hole atom (as new!). Note that , and , . First of all, the common … Continue reading

LOG#167. D-dimensional laws(II).

Let me begin this article in D=d+1 spacetime. We are going to study quantum gases and their statistics in multidimensional space. Usual notation:     In D=d+1 spacetime, the massless free ideal relativistic gas satisfies, as we will show, certain … Continue reading

LOG#156. Superstatistics (I).

This post is the first of three dedicated to some of my followers. Those readers from Mexico (a nice country, despite the issues and particularities it has, as the one I live in…), ;). Why? Well, …Firstly, they have proved … Continue reading

LOG#145. Basic QFT in curved ST(V): the Hawking effect.

Dedicated to the warm memory of my hero as physicist S.W. Hawking. R.I.P. 1942-2018 Idea: Black Holes (BH) are “not” truly black. BH emit thermal radiation at the Hawking temperature and it is proportional to the surface gravity () of … Continue reading
