Around 38 percent of websites that were on the Internet in 2013 are gone now. Half of Wikipedia pages reference dead links. Information seems to be disappearing all around us, and that's nothing new. Over geological time, information loss is the norm, not the exception. Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the originalif you analyze the ashes of the fire, the smoke and the flames to re-create the incinerated words.

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the abundances of the light elements created a few minutes after the Big Bang to understanding the properties of semiconductor materials that are the basis of advanced information technologies. Quantum mechanics is also successful in its exquisitely accurate

Researchers have developed a team of robots that can autonomously explore underground tunnels. A probe maps the interior, while rovers abseil down to explore environments.
