Ancient civilizations such as the Babylonians, the Chinese and the Greeks studied the stars without the benefit of telescopes and yet identified patterns of stars that are still used today. These early scientists collected the first data in the science of astronomy. This program provides students with a summary of the history of astronomy and highlights many important astronomers.

Actors portray prominent scientists and astronomers as they present the history of astronomy from Plato to Newton in its historical and cultural contexts. The Greeks reasoned that the universe was geocentric--the earth was at its center. Not until Copernicus did the theory of the sun as center take root. Each major astronomer declares his different theory until Newton's answers all questions about gravitational pull between planets.
Since the time of the ancient Greeks, humans have been using spider silk to dress wounds. Scientists now know spider webs not only have healing qualities, they can be stronger than steel. University of Wyoming Molecular Biologist Randy Lewis adds an almost science fiction aspect to the study of spider silk: making large quantities of it by “growing it” in goat’s milk. With funding from the National Science Foundation, Lewis has cloned and sequenced genes for the proteins that make up five different spider silks, some stronger than Kevlar, others more elastic than nylon.
Timeblazers Jen and Sam travel back 63 million years before the first primitive people appeared on Earth, and they learn that people and dinosaurs never met. They jump to the Paleolithic age, when humans first appeared, to see some "cavemen," as they are often called. About 8000 BCE the first primitive civilizations began to develop after humans started farming. Then to 3100 BCE: The Egyptians. Around 750 BCE came the ancient Greek civilization; then from about 27 BCE to 476 CE came the Roman Empire. Then came the Middle Ages from 500 to about the year 1400, the Renaissance.
