We are clearly avowed fans of Derek Muller and his channel Veritasium. The quality of each and every one of his productions is outstanding, the topics are exciting, often off the mainstream and not infrequently trigger fierce reactions.

Derek's current video will probably cause less controversy, but that doesn't make it any less interesting. His topic is the Fast Fourier Transform.

An algorithm that is so ubiquitous, that our modern life is hardly imaginable without it. If you haven't heard of FFT yet, this video will definitely make you smarter. But also those who have already worked with an FFT implementation, will understand how the fast part actually comes about. Off-topic but as always super interesting and the official tip-of-the-week™.
