Twin prime conjecture
(Preview)
Mathematicians have taken a giant step towards cracking one of the oldest and most complex number puzzles - without a Sudoku grid in sight.
The puzzle, known as the twin prime conjecture, has stumped the best mathematical brains for centuries.
Of similar status to Fermat's last the...

Formulas
(Preview)
Workers reveal historical formulas sealed behind a wall Twenty-two years ago, workers renovating a WHOI conference room decided that two chalkboards covered in mathematical formulas looked too interesting to throw away. In a corner of one board, they added a few notes, then sealed the boards beh...

Flat mirror
(Preview)
Spanish researchers at the Autonomous University of Madrid claim to have created the most perfectly flat mirror ever, which they think may be useful for creating a new type of microscope. Lead researcher Vazquez de Parga has revealed that his team made the smoothest surface ever by combining silic...

Einstein’s Refrigerator
(Preview)
Oxford engineers aim to build 1930s invention that uses no electricity. Electrical engineers at Oxford University are trying to develop an eco-friendly refrigerator that runs without electricity, and they are looking back to an early invention by Albert Einstein to do it. The team have recently...

Thomas Jefferson National Accelerator Facility
(Preview)
A massive $310m upgrade to the Thomas Jefferson National Accelerator Facility in Virginia has been approved, which will provide physicists with beams of 12 GeV electrons to study the fundamental structure of protons and neutrons. The upgrade will allow scientists to investigate the origins of w...

Virgo gravity-wave interferometer
(Preview)
The Virgo gravity-wave interferometer, an 80 million experiment located outside of Pisa, Italy, has been incapacitated by a vacuum failure for most of the summer, and is expected to stay out of commission for a month or two to come. Much of the lost time, though, would not have been used for observati...

Quantum Chaos
(Preview)
A University of Utah study is shedding light on an important, unsolved physics problem: the relationship between chaos theory - which is based on 300-year-old Newtonian physics - and the modern theory of quantum mechanics. The study demonstrated a fundamental new property - what appears to be cha...

Tug-of-war inelastic collisions
(Preview)
Vibrational excitation through tug-of-war inelastic collisions A new form of energy-transfer, reported today in Nature (3 July 2008) may have implications for the study of reactions going on in the atmosphere, and even for those occurring in the body. The reaction under study is the simplest che...

Bohr atom
(Preview)
Who knew it would take nearly a century to create the Bohr atom? The first successful model of the hydrogen atom was proposed by Danish physicist Niels Bohr almost a century ago and comprised an electron in classical circular "planet-like" orbit about the nucleus. With the advent of quan...

Modern Theoretical Physics - Stanford Course
(Preview)
The old Copenhagen interpretation of quantum mechanics associated with Niels Bohr is giving way to a more profound interpretation based on the idea of quantum entanglement. Entanglement not only replaces the obsolete notion of the collapse of the wave function but is also the basis for Bells famo...
