A New Kilogram in 2018: The Biggest Revolution in Metrology Since the French Revolution
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....

Black holes, Wormholes and Time Travel
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.

Cold Atomic Gases: the Intersection of Condensed Matter and Atomic Physics
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....

Controlling Photons in a Box and Exploring the Quantum to Classical Boundary
The founders of quantum theory assumed in 'thought experiments' that they were manipulating isolated quantum systems, obeying the counterintuitive laws which they had just discovered. Technological advances have recently turned these virtual experi....

Creating Artificial Magnetic Fields to Act on Neutral Atoms
Cold, quantum degenerate gases of neutral atoms have proved to be useful in simulating the behavior of quantum systems like electrons in solids. For example, cold atoms moving in optical lattices (periodic potentials created by interfering laser be....
