Just over a century ago, Einstein proposed the existence of waves in the spacetime continuum – the logical deduction from his Theory of General Relativity. In February 2016, scientists finally announced the detection of those “ripples” in gravity, using the technique of laser interferometry.
Temperature inversions are meteorological phenomena which can occur over busy cities under particular environmental conditions. Retired jet engines could be used as “virtual chimneys”, and draw upwards the resulting smog that clouds the air over some of the World’s most polluted cities.

A meat and potato pie has been attached to a weather balloon, and sent “into space”…

Erm…No. Not Mona Lisa! (Rolls eyes.) Think again!! This is LISA – the Lisa Pathfinder satellite, the key element for a grand new project: a space-based gravitational observatory.

You know how when you throw a rock into a pool, that makes ripples in the water? And how Einstein once upon a time predicted that the very mass of stars and planets should warp spacetime? Although we have had a justified inkling that Einstein was right for quite some time, we had never before detected such a phenomenon. Until THIS happened…

After nearly five hours in space, British astronaut Tim Peake completed his first spacewalk, at 17:31 GMT on Friday 15 January. Intended to last over six hours, the space walk was cut short after his US colleague Tim Kopra reported a water leak in his helmet.
Just like buses, it seems. But even rarer and a damn sight more exciting to be honest. Ooohoo!!! Out with your old Science books!! HeL-LOOooo elements 113… 115, 117 and 118!!

Already this article is beginning to sound like one of those sempiternal quizzes you so often get on social media… but it actually shows how science reality connects. Are you having a scientific identity crisis?

This blog is so cool. It’s spontaneous! It’s electric!! But not as cool as it has been at these cutting-edge laboratories on the outskirts of Europe. Scientists there are dealing with an entirely new type of solid matter – ‘spontelectrics’.

In the run-up to the 2015 physics Nobel prize, which was awarded on Tuesday 6 October, Physics World looked at how Nobel-prize-winning physicists have been moving around the globe over the past century.
