The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

If scientists had sacred objects, this would be one of them: a single, closely guarded 137-year-old cylinder of metal, housed in a vault outside of Paris. It is a prototype that precisely defines a ...

Deluged by responses to his request for your favourite units, Robert P Crease discovers that non-SI units persist, and are sometimes even popular, among the physics community Setting the standard ...

In what could be described as Durham’s biggest contribution to theoretical physics in recent years, a group of physicists have proposed an entirely new unit of time based on the average wait in A&E at ...

When it comes to measuring things, there are some odd units of measurement out there. While measuring in feet is standard, there are many weirder ways to measure. Did you know a hand is a unit of ...
