Many of us can find the time of day quickly and accurately but where did the idea of time keeping originate and how did our ancestors manage without the instant access we take for granted today?

From ancient shadow and water clocks to the latest super accurate optical clocks, Bridget Kendal explores time keeping with the Curator of the Royal Observatory in London, Dr Louise Devoy; the Director of the Museum of the History of Science in Oxford, Dr Silke Ackermann; and watch and clock expert Grégory Gardinetti from the Fondation de la Haute Horlogerie in Geneva.

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.
