Resumen de The eye'S the limit
Brooks talks about overcoming the eyes' sensory limitation. The invention of the microscope, for example, allowed Robert Hooke and others to document hitherto unseen aspects of nature--details of the flea and other disease-bearing parasites, and of course the existence of microbes such as bacteria. Without that knowledge, people wouldn't be living as long as they do. For all the technological sophistication, there is still more invisible stuff to uncover. Dark matter and dark energy together make up 95% of the universe. Neither shines in the conventional way, so they have had to be ingenious to discern what their eyes cannot see. That's how dark matter came to light in the first place: Swiss astronomer Fritz Zwicky was watching galaxy clusters in the 1930s and realized that their motion could only be accounted for by the gravitational pull of invisible mass.
