Now we're in front of the Wells Cathedral clock. It was built by Peter Lightfoot, a Glastonbury monk, in the 14th century, and is one of the oldest clocks still in existence.
It's held here, at the Wells Cathedral.
Now we're meeting with Henry de Vic.
I invented one of the most famous mechanical clocks in 1360, which became a standard timekeeping device until the pendulum clock was invented.
Over there is Jost Burgi, a swiss clockmaker that, in 1577, invented the minute hand for an astronomer who needed a more accurate form of stargazing.
I invented the first pendulum clock in 1656. It lost only a minute a day, which was considered quite an accomplishment at the time.
Now we're with Christiaan Huygens, a dutch scientist.
We're back in England where the first atomic clock was invented in 1949 by Dr. Harold Lyons.
Yup. Throughout history, scientists and clock makers have thrived using collective learning. They've used each others ideas to improve timekeeping, getting us to where we are now. Clocks today, in 2021, are so accurate, they lose one second every 300 million years.
We're back home and boy have we learned a lot. Wall clocks are the most common clocks today but alarm clocks and digital clocks are also very popular.
