Dr Cristina Lazzeroni, a Royal Society University Research Fellow from the University of Birmingham, reveals the secrets of the world's largest accelerator, the Large Hadron Collider and how the LHC experiments hope to answer big questions about the ....

The LHC is the most powerful particle accelerator ever built. It is capable of recreating the very energetic conditions last seen in the universe a billionth of a second after the Big Bang, and allows particle physicists to study the fundamental ingr....

Torques produce angular acceleration, moment of inertia 'resists' it. Rotational kinetic energy and angular momentum.

Peeling sticky tape emits energy that extends into the X-ray regime, reports a study in Nature. The research provides evidence for a phenomenon that was first observed more than 50 years ago.nnIt is well known that unwinding sticky tape produces spar....

Smoot's Nobel Prize was awarded for his analysis of that whisper from the Big Bang, the cosmic microwave background radiation. Today he hopes CERN's data will again transform our understanding of the universe. Young scientists Bilge Demirkoz and Benj....

Awarded a Nobel Prize for using lasers to control and cool atoms, producing the Bose-Einstein condensation, Bill Phillips is eager to hear about new theories from young scientists like Hannah Venzl. An exciting dialogue develops between them on a boa....

Fine tuning the frequencies of light gave John Hall a Nobel Prize, and helped transform the fields of precision measurement and information transmission. Iris Choi and Andrei Ghicov are young scientists excited by the ways physics can change our worl....

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 ....

p=mv. If external forces are zero, momentum is conserved. In collisions, energy may be conserved (elastic) or not (inelastic).

Emily Dougherty presents on the nature and physics of lightning.

Shalini Golla presents on the science behind light.

Kelly Schwirian presents on nuclear power in the United States.
