A linear collider at CERN - from IOPSynopsis:
The boss of CERN wants the next big experiment in particle physics after the Large Hadron Collider (LHC) to be built at the Geneva lab. Speaking in an interview with physicsworld.com, Rolf-Dieter Heuer said that CERN should host the experiment, which would collide electrons and positrons in a linear accelerator. Although a design for the machine has not been finalized by the international particle-physics community, Heuer is keen to bring the collider to CERN.

A Quantum GasSynopsis:
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.		Physics / MechanicsGraduate - ages 21 - 25Bosanac, Slobodan DankoFeb 15, 200837Feedback
Abolishing Time?Synopsis:
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 out all our ideas about both space and time. But he makes young theoretician Itzhak Fouxon, who shares these views, work hard to justify them.		Physics / ForcesHigh - ages 14-19Gross, DavidOct 23, 20096Feedback
Alexander Müller - from Vega.org.ukSynopsis:
K. Alexander Müller shared the Nobel Prize for Physics with J. Georg Bednorz in 1987 ''for their important break-through in the discovery of superconductivity in ceramic materials''. At the age of 9 Müller was given a radio (a single vacuum tube receiver) by his mother and this initiated his interest in science. His teacher encouraged him to take up physics to understand how the radio worked! Muller talks about his religious belief and when asked the question – how did winning the Nobel Prize effect his life he says he has been able to extend his love of old cars!

Color TheorySynopsis:
For my project I am giving a brief history of color theory with emphasis on how science and color theory have interacted. I focus on aspects like primary colors, how color is perceived, and the artists who were at the forefront of color and design. I begin with Newton and his idea of color, and end with the Bauhaus and how color theory is relevant to the future. Trichromatic color vision and opponent process are also discussed pertaining to the RGB primaries.		Physics / LightUndergraduate ages 18-22Ferguson, SarahApr 22, 201012Feedback

Communication with Space Probes and beyond ...Synopsis:
The main problems associated with communicating with distant space probes like Voyager 1 are investigated. The role played by diffraction in limiting the amount of power receivable on Earth is discussed. The further problems of reaching a nearby star are introduced and the inevitable time delay illustrated. 		Physics / OpticsHigh - ages 14-19Byfleet, ColinMar 16, 200925Feedback

A description and demonstration of the way in which craters formed by dropping objects into sand can be linked to some elementary physics 		Physics / MechanicsMiddle - ages 11 - 14Byfleet, ColinSep 21, 200711Feedback
Dark Matter, Dark EnergySynopsis:
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 Benjamin Joachimi question him about how Dark Matter and Dark Energy fit into this picture.		Physics / ForcesHigh - ages 14-19Smoot, GeorgeOct 03, 20090Feedback

Electron Waves Unveil The Microcosmos - from Vega.org.ukSynopsis:
Since the time of Faraday lines of force in space have been ''observed'' by sprinkling iron filings around magnet. The lecturer explains how, with modern techniques we can ''see'' lines of force inside a solid magnet. The studies reveal a fascinating dynamic world in which lines of force form vortices (quantised bundles) that hop and swirl inside a superconductor (much like tornadoes do in the atmosphere). You can use a microscope to see the cell structure of a leaf. Optical microscopes employ waves of visible light. To see smaller objects such as viruses and irregularities in the atomic arrangement of crystals, however, you have to use electron waves. Why? Because wavelengths of visible light are too large to probe such small sizes. Are electrons waves? Yes, they can behave like waves, which are trains of crests and troughs just like the ripples on the surface of water. Using the electron microscope, we can see the crest height and the trough depth of the electron waves after they are disturbed from passing by the objects being examined. However, there are some objects that do not affect the height or depth of the waves, but pull back (or push forward) the crests and troughs. This can be observed by superposing two waves, one pulled back and the other unaffected, and letting them interfere. The electron waves will interfere constructively if the crests overlap, and destructively if the crests meet the troughs. This is the principle of holography, which the lecturer explains in detail during the discourse. Then, you will be able to understand the fascinating sceneries in the microcosmos that electron holography has unveiled, such as the quantised bundles of magnetic lines of force in a superconductor, and how they dance and hop!

Fibre and SunlightSynopsis:
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 world. Hall, now in his seventh decade, inspires them with his own excited enthusiasm for practical science.		Physics / ElectricityHigh - ages 14-19Hall, JohnOct 16, 20096Feedback

Gerardus `t Hooft - from Vega.org.ukSynopsis:
Gerardus `t Hooft, the Netherlands shared the Nobel Prize in Physics in 1999 with Martinus J.F. Veltman, the Netherlands ''for elucidating the quantum structure of electroweak interactions in physics''. He came from a family of intellectuals. His great uncle was a also Nobel Laureate. As a child he was very good at science and mathematics and admired the work of people like Einstein and Bohr. He did most of his work for his Nobel Prize as a graduate student but did not receive the prize until 30 years later. He believes that experts in theoretical physics today can give rational explanations to the entire universe! From his own scientific basis he does not believe in an afterlife.
