Lecture by physicist and biologist Ricard Solé that offers a scientific and emotional journey through the concept of time. Starting from essential questions such as what time is, how we perceive it, what its origin is, or whether we can travel to the past, the session explores how this phenomenon has been interpreted through physics, biology, neuroscience, art, and literature. A reflection that connects major scientific advances with cultural and human visions of the passage of time, memory, and consciousness. The lecture is part of the exhibition “The Invention of Time”, produced by the Museum of Natural Sciences of Barcelona and curated by Ricard Solé, which will open at the Centre Martorell d’Exposicions on December 13, accompanied by a program of activities and a catalogue-book.
