The year 2013 is coming to its end…And I have a final gift for you. An impossible post! This year was the Bohr model 100th anniversary. I have talked about this subject already, here, here and here. The hydrogen spectrum is very important in Astronomy, … Continue reading

In 1905, one of Einstein’s achievements was to establish the theory of Special Relativity from 2 single postulates and correctly deduce their physical consequences (some of them time later). The essence of Special Relativity, as we have seen, is that … Continue reading

Hello, eager earthlings! Today, my list is about fascinating number types. I love them all so much… 1) Natural numbers. 2) Integer numbers. 3) Fractional numbers. 4) Irrational numbers. 5) Real numbers. 6) Complex numbers. 7) Quaternions. 8) Octonions/Octaves/Cayley numbers. … Continue reading

Hello, Earth planet! Hello, earthlings! I want to share with you my list of favourite “superstuff”…Enjoy it: 1) Supersymmetry. 2) Superspace. 3) Supermatrix. 4) Superdeterminant. 5) Supergravity. 6) Superstrings. 7) Super p-branes. . Question: What about or “fractional branes”? 8) … Continue reading

This log-entry is an exploration journey… To boldly go, where no zeta function has gone before… Riemann zeta function The Riemann zeta function is an object related to prime numbers. In general, it is a function of complex variable defined … Continue reading

We are going to learn about the different notions of velocity that the special theory of relativity provides. The special theory of relativity is a simple wonderful theory, but it comes with many misconceptions due to bad teaching/science divulgation. It … Continue reading

LORENTZ TRANSFORMATIONS IN NON-STANDARD FORM Let me begin this post with an uncommon representation of Lorentz transformations in terms of “uncommon matrices”. A Lorentz transformation can be written symbolically, as we have seen before, as the set of linear transformations … Continue reading
