How do big things (like Earth or Moon) come from small things (like quarks and electrons)? How do tiny particles push and pull? How does the world hangs in the balance? Why does E=mc-squared? How does Heisenberg's quantum universe operate? From tiny atoms to vast galaxies, the universe is ours to explore and to know: its particles, its interactions, its laws, its unending surprises. Knowing: The Nature of Physical Law is a triumph of science writing for the non-specialist, which gives readers a confident understanding of the most complex concepts. Munowitz takes us to the edge of modern science, allowing us to peer in further than we would have dreamed possible.
