We live in a world where computer science is ever more present, where most human activities rely on computer programs (music is digital, the press is increasingly consulted online, agriculture is robotic, medicine uses algorithms to decode the entire human genome …), yet most people do not know how they work. Computer science is the ability to break down what you want a machine to do into simple tasks it can perform. It’s a way of thinking that allows you to codify a process and make it achievable.
