Amazing Discoveries
It is difficult to imagine a world without video calls, whether made through a laptop, phone, or camera. Technology has made game-changing innovations possible, such as the ability to work from home. In 1993, researchers at the University of Cambridge discovered that it was annoying to take breaks to get a cup of coffee only to discover that the pot was empty. They therefore invented a device to monitor it and connected a camera to provide their computer with a live stream of the coffee pot. Thanks to these researchers, we can now work from home.
