LOG#190. Fundamental challenges (II).

The main challenge we are left to the 21st century and beyond is to unify every interaction into a single theory. Today, we have two main theories: The Standard Model, for particle physics. The cosmological Standard Model, or -CDM, as … Continue reading

LOG#154. Moonshine and 42: THE PAPER.

“(…) The answer to the Great Question…is…Forty-two(…)” said Deep Thought with infinity majesty and calm (frequently found quote from The Hitchhiker’s Guide to the Galaxy, Douglas Adams, London 1979) Dear readers, yesterday, while I was editing, re-editing and writing my … Continue reading

LOG#150. Bohr and Doctor Who: A=mc³.

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

LOG#094. Group theory(XIV).

Group theory and the issue of mass: Majorana fermions in 2D spacetime We have studied in the previous posts that a mass term is “forbidden” in the bivector/sixtor approach and the Dirac-like equation due to the gauge invariance. In fact, … Continue reading

LOG#041. Muons and relativity.

QUESTION: Is the time dilation real or is it an artifact of our current theories? There are solid arguments why time dilation is not an apparent effect but a macroscopic measurable effect. Today, we are going to discuss the “reality” … Continue reading

LOG#006. Lorentz Transformations(II).

These equations define the most general (direct) Lorentz transformations  and we see they are not those in the previous post! I mean, they are not the one with the relative velocity in the direction of one particular axis, as we … Continue reading

LOG#005. Lorentz transformations(I).

For physicists working with objects approaching the light speed, e.g., handling with electromagnetic waves, the use of special relativity is essential. The special theory of relativity is based on two single postulates: 1st) Covariance or invariance of all the physical … Continue reading

LOG#002. Information and noise.

We live in the information era. Read more about this age here. Everything in your sorrounding and environtment is bound and related to some kind of “information processing”. Information can also be recorded and transmitted.  Therefore, being rude, information is … Continue reading
