Sometimes new knowledge is put to work quickly. For example, many practical uses were found for the laser soon after its invention. Sometimes new knowledge is slow to be harnessed. In 1905 Albert Einstein explained how light can eject electrons from solid surfaces. Physics provides deep understanding of the laws of nature and will continue to help shape the world of the future.
Few careers are more exciting, more rewarding, and more important to society than physics.
