Scientists at work: building the world’s fastest downhill racer

I’d like to say that it’s not every day you get asked to try to break a world record with a speed-obsessed truck mechanic from Grimsby, but for us at the Centre for Sports Engineering Research it’s starting…
There are millions of these lurking in Earth’s backyard. NASA

Gecko sticking forces hold rubble-pile asteroids together

Millions of asteroids of all shapes and sizes are littered throughout the inner solar system. In the past three decades, scientists have spotted as many as 500,000 but many more remain unseen. Many of…
George and Sandra were relieved to hear they wouldn’t actually be filming in space. Warner Brothers

How Harry Potter magic turned Gravity into Oscar gold

The huge success of Alfonso Cuarón’s Gravity at this year’s Oscars is a genuine cause for celebration for much of the UK film industry – not least for the many visual effects artists involved in its creation…
High-resolution gravity maps – such as this one showing Australia and its northern neighbours – were constructed from three billion calculations. Hirt et al

High-res gravity maps: a fundamental force for engineers

Think back to high-school science. Do you remember what the value of acceleration due to gravity at the Earth’s surface - denoted as “g” in textbooks - is? For those whose memories may need a bit of prodding…

Testing the theory: taking Einstein to primary schools

School students today are taught physics based on obsolete theories and outmoded ways of thinking. Instead of the truth, most learn a naive simplification - the 300 year-old Newtonian physics, itself based…
There’s more to gravity than apples falling from trees. Cea

Explainer: gravity

I have spent almost 40 years trying to detect gravity waves. When I started there were just a few of us working away in university labs. Today 1,000 physicists working with billion-dollar observatories…

Does antimatter weigh more than matter?

Researchers have developed, for the first time, a method to efficiently produce long-lived “positronium” – a bound state…
