Lecture: «The power of crystals. Its impact on science, art and thought» taught by Juan Manuel García Ruiz, within the cycle of conferences «The Granada of Science and Innovation in the Ateneo. May 11, 2023. He will speak about the impact of crystals in science, art and thought. Crystals have had and still have a singular attraction for humans. Men and women have been attracted to them since the beginning of our own consciousness. The origin of this attraction is an enigma and probably will be for some time, but what is clear is that the meaning of crystals in culture and religion has changed substantially throughout history. When cinematography was born at the beginning of the 20th century, the idea of glass as an icon of geometric perfection and the power of reason, of the power of intelligence - be it human, extraterrestrial or any other type of intelligence - had already penetrated deeply into culture. He had done it in literature, painting, sculpture and architecture and he was doing it in the new arts, such as comics and, of course, in the cinema.
