How the metre changed the world

Nowdays, if you want to find out how long one metre is, you can use a tape measure or, if you are a scientist, you can calculate the distance that light travels in a vacuum in 1/299 792 458 seconds. But how did we decide on what length a metre should be in the first place?

To follow the far-from-straight story of the metre Quentin Cooper is joined by Professor Robert Crease, historian of science at Stonybrook University in the USA; Professor Marc Himbert, Scientific director of the Metrology Laboratory at CNAM in Paris; and Dr. Jahnavi Phalkey, historian of contemporary and twentieth century science and technology at King’s College in London.

The unfolding history of the magazine

When magazines first emerged, they were the preserve of an elite who could afford to pay for them. But as time went on, the cost of paper fell, printing technology became more streamlined, literacy improved and would-be publishers spotted an opportunity to connect with audiences hungry for information and entertainment.

Magazines found a place to appeal to all types of interest, in the same way that the internet does today. In their heyday they attracted some of the best writers such as Charles Dickens and Ernest Hemingway, sometimes acting as a vehicle to establish literary careers. Later magazines were to become the go-to place for quality photography and design.

Falling advertising revenues have largely contributed to the decline of printed magazines, as well as editions moving online. However some titles have found a way of reinventing themselves in the 21st century.
