| Aristarchus (c.310 B.C.--c.230 B.C.) | Made first mathematically sound attempt at measuring the cosmos. Geocentric model. Bowl-shaped sundial; skaphe. |
| Archimedes (287 B.C.--212 B.C.) | Invented war devices; catapult. Discoveries in math and geometry. |
| ibn al-Haitham (c.965--c.1040) | Islamic mathematician, theorist, experimenter. Claimed objects emanated light. |
| Copernicus (1473--1543) | Heliocentric model. Circular orbits. |
| Galileo Galilei (1564--1642) | First to observe sunspots, rotation of Sun, mountains and depressions on moon, Jupiter's moons. Proved heliocentric model. Designed thermometer, geometric and military compass. Founded scientific study of motion and gravity. |
