Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Science has an important part to play in our everyday existence, and there is far too much neglect of science; but its intention is to supplement not to supplant the familiar outlook.
Arthur Eddington, Science and the Unseen World (1929).
There are solar panels that covert sunlight directly to electricity, and there are others that absorb the sun's rays for hot water. EU-funded researchers have made progress on a solar thermoelectric generator that generates electricity from the sun's heat.
