They can be imagined as crystals whose molecules are able to move around, as in a liquid, while maintaining their relative orientation...Electrical signals in digital displays (thin computer screens as on laptops and the displays of digital watches) flip their orientation switching them between opaque and reflective states." ...

One of the greatest mathematicians of the 18th century, he created the calculus of variations, systematized the field of differential equations and worked on the theory of numbers. Among his investigations in astronomy were calculations of the libration of the moon and motions of the planets.
