University of Adelaide applied mathematicians have extended Einstein’s theory of special relativity to work beyond the speed of light.
Understanding the phenomenon of blackbody radiation – electromagnetic emissions that play a role in a broad range of physical systems – is an important part of physics instruction at both the high school and college level.
Geneva and Frankfurt, 10 October 2012. CERN(1) is today showcasing its science at the Frankfurt Book Fair(2).
The 2012 Massey Lectures feature a personal and fascinating work titled The Universe Within: From Quantum to Cosmos by Neil Turok, Director of Perimeter Institute for Theoretical Physics.
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2012 to Serge Haroche, Collège de France and Ecole Normale Supérieure, Paris, France and David J. Wineland, National Institute of Standards and Technology (NIST) and University of Colorado Boulder, CO, USA “for ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems”.
Serge Haroche and David J. Wineland have independently invented and developed methods for measuring and manipulating individual particles while preserving their quantum-mechanical nature, in ways that were previously tho...
A University of Southampton professor is the only UK recipient of a research grant to explore the laws of physics at the beginning of time.
All the apparatus that fills the laboratory of the Microtraps group at the Centre for Quantum Technologies — three heavy metal optical benches densely packed with lasers, lenses, mirrors and above them shelves full of electronics — has been put into service to produce and probe single ions of Barium.
Scientists who study the ultra-small world of atoms know it is impossible to make certain simultaneous measurements, for example finding out both the location and momentum of an electron, with an arbitrarily high level of precision. Because measurements disturb the system, increased certainty in the first measurement leads to increased uncertainty in the second.
One of the most deeply rooted concepts in science and in our everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. If an event A is a cause of an effect B, then B cannot be a cause of A.
