We find them at the beach, in every sound and light show, the miracle of wi-fi and now in the fabric of space-time itself. But what exactly is a wave?
Easy to remember how to do, hard to figure out how it’s working.

Einstein, an accomplished violinist, claimed that, had he not pursued science, he would have been a musician. That’s worth reflecting on, in the wake of last week’s discovery of gravitational waves.

There’s a good reason you should care about the discovery of gravitational waves, even if you don’t understand the science.

The long awaited discovery of gravitational waves has sent ripples through the scientific world. Here top experts respond to the historic announcement.
Oh hey, I heard ripples in space and time, generated as two black holes merged. Call me back.

Here’s a LIGO insider’s description of how he got the news of a phenomenon that had first been theorized 100 years ago.
When two black holes collide, the resulting gravitational ripples can be felt across the cosmos.

The detection of gravitational waves is the final confirmation of Einstein’s theory of general relativity, and opens up a new window into the cosmos.

Particle accelerators are helping to push forward the frontiers of theoretical physics but they’ve also had more impact on your everyday life than you realise.

Getting tellurium and phosphorus to form a molecule is stupidly hard and not very glamorous. Here’s why it’s worth the effort.
New elements were discovered in early thermonuclear bomb tests.

New elements found in the reactions of nuclear tests during World War II sparked the hunt for additions to the periodic table.

They might only last for a fraction of a second but four new elements have finally won their place in the periodic table. The hunt is now on to find even more.

As the components in electronic devices are shrinking to the nanoscale, even a single atom out of place can disrupt their function. But this also presents an opportunity to make them even better.

After the triumph of general relativity, Albert Einstein spent the rest of his life chasing a unified theory, which eluded him right up until the end.

Physicists are working hard to unite Einstein’s theory of relativity with quantum mechanics. It’s no easy task.
It’s possible that had Einstein not conceived of general relativity, then we’d still be at a loss to explain gravity to this day.

Special relativity was inspired, but it took true genius to conceive of general relativity. Had Einstein not come up with it, it may have taken decades for us to figure it out.

A cubic kilometer of clear, stable ice could help physicists answer big questions about cosmic rays and neutrinos. Hardy scientists collect data via a unique telescope at the frozen bottom of the world.
General relativity didn’t happen overnight, but took several steps to come to fruition.

This month is the centenary of the general theory of relativity. But how did we get from the absolutism of Newton to the relativity of Einstein?
