- Thomas Jefferson (allthetropes.org)
Thomas Jefferson (April 13, 1743 - July 4, 1826) is best known for being the guy who wrote the Declaration of Independence. Later, he became the third president (1801 - 1809) of the United States of America and bought Louisiana from Napoleon. He then sent Lewis and Clark out to explore the newly purchased countryside. Jefferson was also known for designing (he was also an architect) the famous estate of Monticello, which served as his home. In fact, he’s probably the closest the U.S. presidency has ever had to an Omnidisciplinary Scientist, having also studied mathematics, philosophy, botany, music, archaeology, and several languages (notably French, Greek, Latin, Anglo-Saxon, and Gaelic). Not to mention he also founded the University of Virginia as he couldn’t find a university that could handle his terrifying intellect, and his 6,500-odd book collection formed the seed of the current Library of Congress (after the original contents of the Library were burned in the War of 1812). To top it all off, the guy invented macaroni and cheese and the swivel chair - quite probably the sort of chair your butt graces right now!
- Star Tales - Cancer (ianridpath.com)
The crab is a minor character in one of the labours of Heracles (the Greek name for Hercules). While Heracles was fighting the multi-headed monster called the Hydra in the swamp near Lerna, the crab emerged from the swamp and added its own attack by biting Heracles on the foot. Heracles angrily stamped on the crab, crushing it. For this modest contribution to history, we are told that the goddess Hera, the enemy of Heracles, put the crab among the stars of the zodiac. Its name in Greek was Καρκίνος (Karkinos), or Carcinus in Latin transliteration.
- Cancer (constellation) (Wikipedia)
Cancer is one of the twelve constellations of the zodiac and is located in the Northern celestial hemisphere. Its old astronomical symbol is ♋︎. Its name is Latin for crab and it is commonly represented as one. Cancer is a medium-size constellation with an area of 506 square degrees and its stars are rather faint, its brightest star Beta Cancri having an apparent magnitude of 3.5. It contains two stars with known planets, including 55 Cancri, which has five: one super-earth and four gas giants, one of which is in the habitable zone and as such has expected temperatures similar to Earth. At the (angular) heart of this sector of our celestial sphere is Praesepe (Messier 44), one of the closest open clusters to Earth and a popular target for amateur astronomers.
