A
When we think of technology,we tend to think of computers,smartphones,and the Internet among other high-tech inventions.But technological development also applies to clocks.The creation of mechanical gears in clocks was a great leap forward for timekeeping devices.Here are just a few of the milestones in their history.
The Pendulum (钟摆) Clock
While clocks using springs and gears had already been invented by the 1500s,it was the pendulum clock developed by Christiaan Huygens in 1657 that gave timepieces a higher level of accuracy.The improvements Huygens made to the pendulum design made it 100 times more accurate than previous clocks.Rather than losing or gaining 15 minutes per day,Huygens’ pendulum clocks were accurate within a minute per week.
The Power of Electricity
Clocks that used a battery began to be developed around 1815,but it wasn’t until 25 years later that a Scottish clockmaker named Alexander Bain patented a clock powered by an electric current.Bain’s clock still used a pendulum,but the pendulum was powered by electromagnetism.More than a hundred years later,in 1957,the first electric watches became available to the public.
Portable Watches
As clock technology advanced and mechanisms became more accurate and thinner,new types of timepieces that could be carried on a person were developed.The earliest of these were pocket watches,which were created in Switzerland in 1574.Centuries later,in 1812,Abraham-Louis Breguet produced the first wristwatch,which he gave to the Queen of Naples,Napoleon’s younger sister.Originally,wristwatches were worn by women only and men continued to use pocket watches.
