On alarm clocks

An alarm clock combines the function of a clock with a warning device to alert people when a certain time has come. The warning device - the alarm - has taken different shapes throughout history. However, they normally rely on a system of vibration, sound, or visual display. 

The alarm clocks have two main functions: to awaken people from their sleep and to work as a reminder to signal a certain event or activity.

The origins of the first alarm clocks are still unknown, but there are reports of the existence of primitive devices with a similar role already back to the centuries BC. A notable example is that of Plato, in ancient Greece. It is said that the philosopher had a large water clock with an embedded unspecified alarm system that would make the water sound like an organ. This fact is yet unconfirmed. The reason behind the alarm is also unknown, but it is believed that it was a device set to signal the beginning of his lectures at dawn. 

In the following centuries, alarm clocks were mostly used by religious institutions to announce the time for prayers or other community events. There are reports of individual (successful) attempts of making personal devices but they were far apart and were never patented or for sale. 

The first user-settable alarm clock that we could today recognize as such was first patented in 1847 by a French inventor. Since then, the devices have not stopped evolving. Radio was the first extra feature added to them, then cassette players followed by CD, iPod, and Bluetooth players, etc.

Nowadays, alarm clocks are available on computers, mobile phones, watches, and radio and clock devices, proving the important role that came to take on our daily routines.
