Born in Madrid in 1972. When he was little, he loved science-fiction movies, because he was amazed with special effects. Above all, he loved it, because he was always leaving the cinema with a question in his head. Perhaps, some of the movies are guilty his future choices of Telecommunication Systems Engineering as a field of study.
When during the crisis he found himself being unemployed, he decided to fund an academy. Unfortunately, that same crisis prevented many of his students from being able to pay for their studies. Thereby, he decided to open a YouTube channel – the only way that allowed the students to follow the classes. Today, he is having over a million of subscriptions (he has just received another Golden Play Button from YouTube), his channel is a reference for the world of education world and the Spanish-speaking scientific environment, becoming the first science channel in Spain and one of the three most followed channels in Spanish language.
David Calle also uses the channel to contribute to the greater cause and now, altogether with his book, he promotes vocations at STEM (Science, Technology, Engineering and Mathematics), especially among women. Development of these competences is one of the fundamental objectives of the educative agenda, not only for the European Union and United States, but also for the international organisations.
