A couple of months ago I wrote here about the first observation of a process called "diboson production", a quite rare occurrence in hadronic collisions: for the first time, the CDF collaboration…

"Full many a gem of purest ray sereneThe dark unfathomed caves of ocean bear;Full many a flower is born to blush unseen,And waste its sweetness in the desert air." Thomas Gray, "Elegy Written in a…

Scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory in the US, have performed sophisticated laser measurements to detect the subtle effects of one of…

The Principle of Maximal Aging - Capturing the Essence of Relativity Ever wondered what is the longest path from A to B? I will give you a definite answer in a minute. Stay tuned.  We…

The hunt for dark energy is on and ways to find it, such as weak gravitational lensing and baryon acoustic oscillation, hold great promise but are as yet unproven.   Supernovae studies, which…

Robert Wald has formulated QFT in curved space time in terms of it's algebra of observables on a manifold.  In doing so he has, perhaps unintentionally, provided framework in which very…

Readers familiar with this blog know that I am a die-hard skeptic on the issue of physics beyond the Standard Model. However, today I am wearing my fluctuation-enthusiast hat, and I will be trying to…

Call it irreversibility, call it time's arrow, call it the second law of thermodynamics. Fact is that everything evolves in such a way that things get more messy. Disorder rises. Entropy increases.…

Detailed balance is a simple and powerful rule to describe the dynamics of two-state systems. If you know the probability of a transition from a state A to the other state B of a physical system (in…

Previously thought to be indivisible, with negative charge for all, the electron is one of the fundamental building blocks of nature. A new experiment, however, has shown that electrons, if crowded…
