Logical Foundation of Theoretical Physics

    Fundamental Theoretical Physics contains sequences of theories, each of which is explained by previous ones by rules of the classical logic. For example, optics is absorbed by the theory of electromagnetism, classical mechanics- by the special theory ...

Multiverse 101?

This article is about physics but it fits under random thoughts also. My writing here on Scientific Blogging is self-educational, about what I am wondering and learning about. Today, it's multiverse theory. ...

New Rare B Decays Nailed By CDF: The Door To New Physics?

The CDF Collaboration has recently produced a new analysis of proton-antiproton collisions at the now second-world-best collision energy of 1.96 TeV. They searched for very rare decays of the B mesons, particles composed of, would you guess, a b-quark and ...

Feynman Explains Quarks With A Burp

"One way of thinking about the confinement problem was suggested by e+ e- annihilation into hadrons. Initially, the virtual photon dissociates into a quark and an antiquark that move with almost the speed of light back-to-back. Feynman had argued tha ...

Triggering- The Subtle Art Of Being Picky

The success of today's particle physics experiments relies to a surprisingly large extent on a seldom told functionality of the giant apparata that detect the faint echoes of subatomic particles hitting or punching through their sensitive regions: the ...

It From Bit- How To Get Rid Of Dark Energy

Our universe expands, and this expansion is accelerating. Current consensus is to attribute this acceleration to a mysterious form of energy: dark energy. This dark energy density is very tiny and therefore only notable at cosmic length scales. When expre ...

Particle Physics In 2020

2010 has just started with the best auspices to bring us exciting new science, and there comes a pledge to forecast what will happen in 2020. Oh, well- rest is not what I became a scientist for. Making non-trivial predictions today for how will basic resea ...

Plot Of The Week- Supersymmetric Higgs Bosons Of The Third Kind

I have no energy today to put together a detailed discussion of a brand new, exciting search for supersymmetric Higgs boson performed in data collected by the CDF experiment at the Tevatron proton-antiproton collider. All I can do for you is to show the in ...
