1. Galileo Galilei (1564–1642), an Italian thinker and key figure in the scientific revolution who improved the telescope, made astronomical observations, and put forward the basic principle of relativity in physics.

   The field’s practitioners believe that as they learn to read the universe using neutrinos, they could make new, unexpected discoveries — much as the lensmakers who first developed the telescope could not have imagined that Galileo would later use it to discover the moons of Jupiter.
