Q: The first recorded one of these goes back over 2400 years. This invention has been refined over the years and almost all of us use one every day. What is it?
A: The Alarm clock.
Dating to the year 725, Yi Xing’s ingenious version of an alarm clock is one of the world’s earliest recorded devices of that nature. Along with the water clock Plato used to wake himself up for his legendary dawn lectures in the 4th century BCE, it is evidence that humans have been looking for ways to rise on time for thousands of years.
