This my last normal post. Welcome to those who read me. TSOR is ending and from its ashes will arise another project. That is inevitable. I want to use new TeX packages, and that is not easy here, to … Continue reading

3 posts to finish the TSOR adventure! This blog post will introduce you to basic string theory from my own biased viewpoint. My blog, my rules. I think you concede that! What is the Universe made of? This really ancient … Continue reading

Introduction One of the big issues of Standard Model (SM) is the origin of mass (OM). Usually, the electroweak sector implements mass in the gauge and matter sector through the well known Higgs mechanism. However, the Higgs mechanism is not … Continue reading

Newtonian gravity is not coherent with special relativity. Einstein was well aware about it and he had to invent General Relativity (GR). Armed with the equivalence principle, a mystery since ancient times of Galileo, the equivalence between inertial and gravitational … Continue reading

Some fundamental mottos: Fundamental spacetime: no more? Fundamental spacetime falls: no more? Fundamentalness vs emergence(ness) is an old fight in Physics. Another typical mantra is not Shamballa but the old endless debate between what theory is fundamental (or basic) … Continue reading

I am going to review the powerful Cartan calculus of differential forms applied to differential geometry. In particular, I will derive the structure equations and the Bianchi identities. Yes! Firstly, in a 2-dim manifold, we and introduce the Cartan 1-forms … Continue reading

Jacobi elliptic functions allow to solve many physical problems. Today I will review briefly some features. Let me first highlight that the simple pendulum, Euler asymmetric top, the heavy top, the Duffing oscillator, the Seiffert spiral motion, and the Ginzburg-Landau … Continue reading

Flatland is a known popular story and book. I am going to review the Bohr model in Flatland and, then, I am going to strange fractional (or fractal) dimensions, i.e., we are going to travel to Fracland via Bohrlogy today … Continue reading

Quantum Mechanics, is it unbreakable? Is it effective or fundamental? Could it be an approximation to another theory? We do not know the ultimate word about that. However, up to current date (circa 2019), it is fundamental. Any trial and … Continue reading

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
