Snakes include some infrared in their reality, and honeybees include ultraviolet in their view of the world, and of course we build machines in the dashboards of our cars to pick up on signals in the radio frequency range, and we built machines in hospitals to pick up on the X-ray range. But you can't sense any of those by yourself, at least not yet, because you don't come equipped with the proper sensors.
Las serpientes perciben rayos infrarojos las abejas rayos ultravioletas, y, claro, construímos máquinas en los tableros de nuestros autos para capturar señales en el rango de frecuencias de radio, y construímos máquinas en hospitales para capturar rayos X. Pero no podemos percibir esto solos, al menos no todavía, porque no venimos equipados con los sensores adecuados.
