Superposition Principle And Causing Collapse

One of the most basic laws of quantum mechanics is  the superposition principle- a system can be in more than one state, that is to say it can exist in multiple realities, at once. This phenomenon exists only until the system is observed or measured in so ...

Cuprate Superconductors- Where Are The Missing Electrons?

While there are still plenty of mysteries in electromagnetics, electrical engineers are sure of one thing; current is carried through materials by flowing electrons.  In physics, Luttinger's theorem states that the number of electrons in a material i ...

The Boson Quandary

Here I vow to never "reblog", but exceptionally I will break that rule, translating from Italian a very nice article recently appeared on the Italian newspaper "Il Sole-24 Ore". The author is the INFN President, Fernando Ferroni. The r ...

Relativity, cosmic rays, cosmology and spinorial space-time (II)

Sorry, I again spent a long time without writing anything here... I hope you are having a happy 2013 in spite of all kinds of "sequestrations" on both sides of the Atlantic. Here are my two last papers. They will appear in the Proceedings of the ...

The Quote Of The Week- Zen Moment For a Dark Matter Seeker

"...spend one year one mile underground to stare at a bucket of xenon... only to come out for your zen moment and profoundly declare "nothing happened"... and then you spend twice as long wondering how you allowed yourself to be talked into ...

Planck Results Are Out!

The Planck collaboration has released today data from the first 16 months of operation of their space instrument (see left). There will be a live streaming of their announcements to the public in 1.5 hours at this link. ...

Planck confirms WMAP results, and is largely silent on theoretical astrophysics.

From the perspective of one theoretical particle physicist Planck found far from "nothing". The ESA's Planck probe largely corroborates the findings of NASA's WMAP probe, but it leaves theoretical astrophysics unsettled. After reading ...

Are Physics Conferences A Waste? An Ethical Issue

The number of conferences held every year around the world to present and discuss topics in frontier particle physics is surprisingly large: over a hundred per year. Just look at the following list of conferences scheduled in the last three weeks for a pro ...

Eventually, The Tevatron Also Sees The Higgs!

I think I wrote a post about the "definitive results" of the CDF and DZERO experiments on the search for the Higgs boson at least a couple of times already in the past, but you know, these busy experimentalists continue to improve their analyses, ...

Rescinded: The Light Matter Proposal: The Effect of Fusion on the Velocity Profile of a Disk Galaxy

I have decided to rescind this proposal.  Stars in a galaxy travel at one velocity, light at the speed c.  There is only one velocity involved in applying the product rule to the definition of a force as a change in momentum.  Note that is not a trivial a ...
