The mystery of how Father Christmas can deliver presents to 700 million children in one night, fit down the chimney and arrive without being seen or heard has been 'solved' by a physicist at the University of Exeter.
Experimental physicist Prof. Thomas Zentgraf and his two colleagues from the University of Birmingham, Dr. Guixin Li and Prof. Shuang Zhang, have for the first time proved experimentally the nonlinear rotational Doppler effect ...
It sounds obvious. That's what night is. The sun has set and when you look up at the sky, it's black. Except where there's a star, of course. The stars are bright and shiny.
The unprecedented sensitivity of space telescopes has powered a revolution over the past decade in our understanding of galaxies in the young universe during its first billion years of existence. These primitive objects are ...
Many animals exhibit segmental patterns that manifest themselves during development. One classical example is the sequential and rhythmic formation the segmental precursors of the backbone, a process that has been linked ...
We know we live in an expanding universe but it's also changing colour and has been doing so for billions of years.
Anyone wanting to avoid being caught out by speed cameras can do so very simply - by obeying the speed limits.
Investigators are closer to solving an international aviation mystery thanks to a British communications satellite and classroom physics.
There are so many galaxies in the universe that if you point a telescope in any direction in the night's sky you are bound to see some.
