- The Future Affects The Past? Welcome To The Quantum Universe
-
Suppose we we tell you everything quantum mechanics can tell you about a quantum particle; what do you really know? Unfortunately, you still cannot predict with certainty the outcome of a simple experiment to measure its state. All quantum mechanics can of ...

- Future Physicists In Belluno
-
On Friday I traveled to Belluno, a town just south of the north-eastern Italian alps, to give a lecture on particle physics to high-school students for the " International Masterclasses ". This was the umpteenth time that I gave more or less the ...

- Neutrinos From An Atomic Bomb
-
Less than three weeks separate us from the XVI Neutrino Telescopes, a very interesting conference held in Venice every two years. The physics of neutrinos is a very special niche in the realm of particle physics, one not devoid of cunning experimental tech ...

- Tautological Description-Relativistic Metaphysics IS The Theory Of Everything
-
Modern physics is not accidentally relativistic and quantum, or in other words, Einstein-relative as well as Everett-relative (Bell-violating Everett-relativity is the very core of quantum mechanics!). Modern physics becomes ever more relativistic still ...

- The Quote Of The Week: Resolving The Mass Hierarchy With A Little Help From A Supernova
-
"1. Interaction with matter changes the neutrino mixing and effective mass splitting in a way that depends on the mass hierarchy. Consequently, results of oscillations and flavor conversion are different for the two hierarchies. 2. Sensitivity to the ...

- Wikipedia's Unbearable Lightness
-
Wikipedia's definition of energy can only be qualified as useless. Here is mine: A bird that flies, a molecule in a gas possess energy since they move: this is kinetic energy. A stone you hold still in your hand could move and therefore acquire kine ...

- New CP-Odd Higgs Boson Results By ATLAS
-
The paper to read today is one from the ATLAS collaboration at the CERN Large Hadron Collider-my competitors, as I work for the other experiment across the ring, CMS. ATLAS has just produced a new article which describes the search for the CP-odd A boson, ...

- How Would Life Develop If Fundamental Physics Constants Were Different?
-
By Gabriel Popkin, Inside Science (Inside Science)-- For all the progress physicists have made in figuring out the universe, they still don't know some pretty basic things. Why, for example, do fundamental particles possess the specific values of mas ...

- A new way to cool larger objects with light
-
An international team of physicists from Russia and Germany have successfully applied a theory from 2009 to cool a relatively large macroscopic mirror (1.2 millimeters across) with lower fundamental frequency (~136 kHz) from room temperature to 126 mK. Th ...

- Smaller fusion reactors for same energy output
-
It has long been accepted that large power output requires big-sized fusion reactors. But, based on calculations performed on beta plasma parameter 1 by researchers from Tokamak Energy, UK, a company that builds compact tokamaks, size is not a significant ...
