Why is it that you can warm your hands by blowing gently against them and cool them by blowing hard? The answer requires a clear understanding of physics and a rudimentary knowledge of the workings of the human body. And how is the vanishing elephant trick carried out? This feat, which probably had its heyday […]

New evidence that solar neutrinos can change "flavour" confirms that our understanding of the Sun is correct and that neutrinos have mass

Packaging materials that display animated adverts and containers that sound an alarm if their contents go mouldy are just two possibilities that could result from a new area of technology called “paper electronics”. The substitution of paper for semiconductors in electronic components might sound bizarre, but Swedish physicists are currently developing devices that can […]
The multitude of energy levels found in molecules has so far defeated the use of laser-based techniques, which rely on exciting transitions that can spontaneously radiate and return to the original levels. Many other ingenious methods have been invented to slow, cool or trap molecules. Paramagnetic molecules have been cooled to sub-kelvin temperatures in a […]
Moreover, the material in question – an organic crystalline solid called lambda-(BETS)2FeCl4 – contains a large concentration of magnetic ions (S Uji et al. 2001 Nature 410 908). The discovery by Shinya Uji of the National Research Institute for Metals in Tsukuba, Japan, and co-workers at the Institute for Molecular Science, the Electrotechnical Laboratory and […]

The report was commissioned from the Institute for Employment Studies by the physics programme of the Engineering and Physical Sciences Research Council (EPSRC) to examine the views of organizations that employ postgraduate physicists. University physics departments in the UK produce about 800 new physics PhDs every year, about 200 of whom have been funded by […]
Surface acoustic waves are commonly found in the electronic circuitry of everyday appliances, such as mobile phones and televisions, where they are used to filter frequencies. Surface acoustic waves are also employed in transponders to transmit signals that are modulated in amplitude and frequency to remote locations. In one recent advance, Thorsten Hesjedal of Stanford […]
