Quasiparticles
(Preview)
Weizmann Institute physicists have demonstrated, for the first time, the existence of 'quasiparticles' with one quarter the charge of an electron. This finding could be a first step toward creating exotic types of quantum computers that might be powerful, yet highly stable. Fractional electro...

Bohmian mechanics
(Preview)
The question of whether quantum mechanics is correct could soon be settled by observing the sky and there are already tantalizing hints that the theory could be wrong. Antony Valentini, a physicist at Imperial College, London, wanted to devise a test that could separate quantum mechanics from one...

Space boomerang
(Preview)
"Remember the astronaut who recently tested whether boomerangs return to their throwers in the absence of gravity? Well, the Japan Aerospace Exploration Agency has released video of astronaut Takao Doi showing that the objects do, in fact, come back - even in the microgravity environment o...

Texas Petawatt Laser
(Preview)
Physicists have turned on the world's most powerful laser, whose pulses are more intense than any known light source in the universe. The incredible temperatures and pressures it generates when it hits a target will let scientists explore conditions found in exploding stars and the cores of giant...

Maxwell Equations
(Preview)
Title: On First Order Generalized Maxwell Equations Authors: S. I. Kruglov (Version v2) The generalized Maxwell equations including an additional scalar field are considered in the first order formalism. The gauge invariance of the Lagrangian and equations is broken resulting the appearance...

Alfven waves
(Preview)
Here's a strange scenario: You move farther away from a fire, getting cooler and cooler, until suddenly you are burning up. That's essentially what happens in the sun: Its outer layer, the corona, is inexplicably hot. A new study may complicate things further by poking holes in a leading theory that...

Y(3940)
(Preview)
Physicists may have discovered the first "hybrid meson" at the KEK laboratory in Japan.
The meson, first predicted over 25 years ago, appears to contain a gluon in addition to the quark and antiquark that are usually found in mesons. The new meson is currently known as the Y(394...

optical lattice clock
(Preview)
A clock 1000 times more accurate than any of its predecessors has set another benchmark, and could even be used to create a more precise definition of how long a second is.
The new clock is a variant on the atomic clocks that appeared in the 1950s. Atomic clocks usually work by measuring the frequency...

Schwarz-Christoffel formula
(Preview)
A problem which has defeated mathematicians for almost 140 years has been solved by a researcher at Imperial College London. Professor Darren Crowdy, Chair in Applied Mathematics, has made the breakthrough in an area of mathematics known as conformal mapping, a key theoretical tool used by mathe...

Preons
(Preview)
Splitting the quark If quarks are made of preons, then stars made of the stuff should be detectable. Are there pea-sized objects as heavy as the Moon out there in space? Perhaps so, if quarks, the constituent particles of atoms, are themselves made up of still smaller particles. Fredrik Sandin and Jo...

Silver(I)hexacyanocobaltate(III)
(Preview)
Ag3Co(CN)6 Most materials contract when they are cooled and get bigger when they are warmed up. But some substances do the opposite by shrinking in certain directions as they are heated and expanding when cooled. Now researchers in the UK have found an inorganic crystalline material composed of si...

New Complex Quantum Mechanics Mathematics
(Preview)
I thought I would put this under weird stuff as it requires new thinking. Do not think that I am not serious though, thanks. Now I discovered that I could rewrite complex mathematics and saw that QM is limited by mankind's present mathematics be it calculus or other. The advantage this gives me is that w...

University of Arizona physicists have discovered that "super crystals" -- crystals which are hundreds to thousands times larger than conventional crystals -- exist in certain organic semiconducting solids. Pure super-crystalline organic semiconductors will conduct electrici...

Sodium

Almost exactly 200 years ago, sodium was isolated as an elemental metal during electrolysis of molten sodium hydroxide (caustic soda). This was announced on November 19, 1807, by Sir Humphry Davy, in the Bakerian Lecture of the Royal Society, along with another new alkali metal, potassium (from m...
