In October 2011 we celebrated the centenary of the Solvay conferences that played a unique and important role in the development of twentieth century physics, most notably in the quantum revolution whose birth overlapped the initiation of these meeti....

Light, particularly sunlight, is believed to be good for our health. Many ancient civilisations even attributed it with mystical healing powers.Renowned for his entertaining lectures, Professor David Phillips, President of the RSC, uses his expertise....

Metrology - the science of measurements - is responsible for the international uniformity and precision in standards. Today, the seven units for meter, kilogram, second, ampere, kelvin, mole, and candela of our international system of units (SI units....

The quantum gas is an extreme state of an ensemble of atoms when their de Broglie wave length is of the same length as the size of the container. The ways of achieving this state are described and also how its temperature is defined.

David Gross's Nobel Prize was for work on the 'strong' force which acts between quarks inside the atom. Now he works on string theory, hoping to understand how all the forces of nature could be united. He believes the next steps may involve throwing ....

Dr Brian Cox takes us on a tour of the Large Hadron Collider where the conditions moments after the Big Bang are to be recreated.

The idea of time travel makes great science fiction, but can it really be achieved? Paul Davies, Visiting Professor of Physics at Imperial College, describes wormholes in space and other ways that might allow travel into the past or future.

An unusual look at the effects that things rotating have on our everyday life.

A review of High Energy Particle Theory and Phenomenology at FSU

In finite objects, the total external force equals the total mass times the acceleration of a point called the centre of mass.

Uniform circular motion: angular displacement and velocity are introduced and centripetal acceleration is determined.

During the past decade laser cooling and evaporative cooling of atoms have produced quantum degenerate gases both of bosons (Bose-Einstein condensates) and of fermions (gases with temperatures below the Fermi temperature). Such gases can provide ana....
