As the UK prepares to celebrate Einstein Year in 2005, a physicist from Bristol University is looking for stories that can be used to tell taxi drivers what physics is all about. Sir Michael Berry, whose own father was a London cabbie, thought of the idea after failing to give a taxi driver a clear explanation of what it is that physicists actually do. Berry realized that physicists need a stock of good and convincing stories that show how physics affects peoples lives. Looking back, he now wishes that he had told the driver how physics has democratized music, by creating the laser, which allows music to be played on a CD almost anywhere. Berry also wishes that he had said how physics has led to GPS navigation devices - the first consumer product to take advantage of Einsteins general theory of relativity. The best stories will be published in a future issue of Physics World.
Radiation – how much is good for you?
Anti-nuclear activists have always argued that even a tiny dose of radiation is bad for the human body. But according to a radiation biologist at Washington State University in the US, that view may be wrong. Antone (Tony) Brooks, who is involved in a low-dose research programme sponsored by the US government, says that the impact of small amounts of radiation is much more complicated than previously suspected. They have a cocktail-like mixture of beneficial and harmful effects that can, on balance, be harmless below a certain threshold. As Robert P Crease explains, this change of view could have huge social and economic consequences.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
