as a Research and Learning Tool for Cosmochemistry

The digital age has transformed the ways by which we live and work. Surprisingly, it is still challenging to agree on a general definition of what digital really means. There is a telltale picture taken by film director Stanley Kubrick in 1946 of people in the New York City (USA) subway. In this picture, almost all the commuters are looking down and into their newspapers. If you now replace the newspapers with smartphones, then the scene might have been shot on a subway today. But there is at least one crucial difference between the two pictures: information density. A newspaper holds only a few tens of kilobytes (kB) of information, whereas a smartphone can hold up to a terabyte (TB). This is six to eight orders of magnitude more than a newspaper. Furthermore, almost all the exabytes (260) of information by humankind has become accessible to us via the internet and through our smartphones. In combination with apps, this vast amount of information is structured and tailored to all our various daily needs. This is the power and attractiveness of digital: the vastness of the information has been condensed, structured, and made accessible through digital devices such as smartphones. Hence, if we use computers solely for calculations – their initial purpose – this is not what we mean by digital.
