Procesamiento de Señales en la Física

We are in the middle of the information age, where technological advances proliferate. In this talk we address the essential ingredient of practically any observable phenomenon today, from the social life of humans, economic growth or audiovisual editing, to the age of the Universe. We see that its operation is based on the propagation and quantification of energy. We finish by relating that process to the controversial concept known as neural networks, which will provide us with a compelling and no less ambitious foundation to study reality.
