A plaque to John Harrison was opened by Prince Philip at Westminster today. Prince Philip is like the Queen's back-up and so it shows that he was quite interesting.
John Harrison was born in 1693 which is alot before the Victorians and alot after the Romans-we've done the Romans at school and the Victorians just invented one thing after another so they are quite interesting too. John Harrison was brilliant and invented the sea clock. This was a way of tracking time and speed at sea, so sailors knew where they were. Before that, they had no way of knowing exactly where they were-they were actually 'all at sea', at sea.
