Physics

I am spending the week in the pleasant resort of La Biodola, in the Elba island. Elba is a beautiful island just off the coast of Tuscany. Here Napoleon was exiled after his abdication in 1814 (he…

The laws of physics are absolute - in theory.  And with an exception. So absolute doesn't always mean what we think it means. How heat and temperature related to energy, the laws of…

Some Sun-like stars are 'earth-eaters.' During their development they ingest large amounts of the rocky material from which 'terrestrial' planets like Earth, Mars and Venus are made. Trey Mack, a…

I came to know through a social network (I have many colleagues as friends there, and they usually post more useful stuff than cute kittens) that ATLAS has launched a very intriguing competition. One…

Physicists say they have discovered how to create matter from light - a feat thought impossible when the idea was first theorized 80 years ago. There is just one problem. In order to test the newest…

In this blog, I will review my thoughts on the action of general relativity, how it is used for the field equations and equations of motion.  There is much to consider, so perhaps this will…

Two months after the controversial BICEP2 announcement, The Washington Post writes « Big Bang backlash: BICEP2 discovery of gravity waves questioned by cosmologists » and National Geographic…

"Subatomic particles act in quantum ways—they have a wave-like nature—and so can atoms, and so can whole molecules since they're collections of atoms," Schwab says. "So the question then is: Can you…

I receive much crackpot email. There is a very common misunderstanding often central, one I have not seen a good answer to anywhere. This is partially due to that few who write about physics counter…

Very recently, a combination of the precise measurements of the mass of the top quark obtained by the CDF and DZERO experiments at the Fermilab Tevatron collider with those produced by the ATLAS and…
