Some things in science are worth waiting for. Sometime towards the end of this year, one of the rarest events in science is expected to occur. In a display case in the lobby of the physics department at the University of Queensland in Brisbane, Australia, a small drop of black tar distillate known as pitch […]

Pitch-drop custodian dies without witnessing a drop fall
John Mainstone, who for 52 years tended to one of the world’s longest-running laboratory experiments but never saw it bear fruit with his own eyes, died on 23 August after suffering a stroke. He was 78. Mainstone had been looking after the pitch drop experiment at the University of Queensland in Brisbane, Australia since he arrived at the university […]
Slow science
The world’s longest-running experiments remind us that science is a marathon, not a sprint. Although science is a long-term pursuit, research is often practised over short timescales: a discrete experiment or a self-contained project constrained by the length of a funding cycle. But some investigations cannot be rushed. To study human lifespans or the roiling […]
