Physical history

21 January 2014


Modern scientific apparatus, all LCD screens and wipe-clean plastic, might be practical and powerful, but it lacks soul.

Surprisingly, perhaps, the age of brass and hardwood is not that far back in history. These two historic instruments, on display in UCL Physics & Astronomy, are less than a century old, yet they look like they come from a totally different age.

Above is a large demonstration model of a galvanometer (a device which measures electric current), with over-sized parts and a glass window to make them easier for students to see during classes. It was built around 1920.

Below is a mid-20th century manometer, a type of pressure gauge.

The upper attachment contains a small glass window (facing away from us in this photo, but visible in this close-up) through which readings would be taken.
