Study Notes
Hipparchus
- Active from 190-120 B.C., pivotal in astronomical history.
- Known for cataloging 850 stars and founding trigonometry, significantly advancing celestial navigation.
- Researched the precession of the equinoxes, influencing future astronomers.
Ptolemy
- Lived from 100-170 A.D., a key figure in ancient astronomy.
- Developed the Ptolemaic system, a geocentric model of the universe, which dominated for centuries.
- Authored the "Almagest," a comprehensive astronomical treatise.
Copernicus
- Flourished between 1473-1543 A.D., known for proposing the heliocentric theory, positioning the sun at the center of the universe.
- Experienced personal loss as he was orphaned at the age of ten.
- His work paved the way for subsequent astronomical discoveries, coinciding with the era of Christopher Columbus.
Galileo
- Lived from 1564-1642 A.D., innovated the use of the telescope in astronomy.
- Discovered four significant moons of Jupiter, expanding knowledge of celestial bodies.
- Home-schooled until age 11, demonstrating early aptitude in science.
Kepler
- Active from 1571-1630 A.D., known for formulating laws of planetary motion.
- Practiced Christianity, influencing his scientific perspective.
- Witnessed the Great Comet of 1577, which fueled his interest in astronomy.
Cassini
- Lived from 1625-1712, known for his work on Saturn's moons.
- A space probe is named after him, acknowledging his contributions to space exploration.
- Made significant observations about the distance of Mars, enhancing knowledge of our solar system.
Newton
- Born in 1643 and passed away in 1727, regarded as the father of modern physics.
- Formulated the Three Laws of Motion, laying the groundwork for classical mechanics.
- Made notable contributions to calculus, and famously (though apocryphally) stuck a needle in his eye during an experiment.
Banneker
- Lived from 1731-1806, renowned for predicting solar eclipses and creating almanacs.
- Notably born free in an era of slavery, contributing to his prominence in science.
