Is pitch a liquid or a solid? It turns out that while it appears to be a solid at room temperature, it actually flows like a liquid ... a very, very viscous liquid. Why is this interesting? One of the ...

“Oh yes, watching paint dry would be far, far more interesting,” says Andrew White, a quantum physicist at Australia’s University of Queensland and custodian of the world’s longest continually run — ...

It took seven decades, but the pitch has finally been caught in the act. Since 1944, physicists at Trinity College in Dublin have been trying to measure the viscosity of pitch tar, a polymer seemingly ...

It may have taken 69 years but one of the longest-running experiments in the world has captured the fall of a drop of tar pitch on camera for the first time ever. The experiment began in 1944 at ...

The Pitch Drop experiment started in 1927 at the University of Queensland, remains one of the most engaging examples of long-term research and fascinating behaviours of mundane materials. This ...

A clever tweak is letting students “cheat” at one of the world’s longest running experiments. Although pitch – or bitumen – seems solid at room temperature, it flows like a liquid given enough time.

SCIENTISTS are no more immune from the hustle of modern life than anybody else. But some specialisations—astronomy, geology, evolutionary biology, to name just three—offer a broader perspective, ...
