- I was ready to look for other truths. I imagined the object of geometry, which I thought of as a continuous body or space that extends indefinitely in length, width, and depth, which can be divided into parts with different shapes and sizes, and can be moved or rearranged in various ways. (This is what geometers assume is in the object they study.) I reviewed some of their simplest proofs.
- Horologium (constellation) (Wikipedia)
Horologium (Latin hōrologium, the pendulum clock, from Greek ὡρολόγιον, lit. ‘an instrument for telling the hour’) is a constellation of six stars faintly visible in the southern celestial hemisphere. It was first described by the French astronomer Nicolas-Louis de Lacaille in 1756 and visualized by him as a clock with a pendulum and a second hand. In 1922 the constellation was redefined by the International Astronomical Union (IAU) as a region of the celestial sphere containing Lacaille’s stars, and has since been an IAU designated constellation. Horologium’s associated region is wholly visible to observers south of 23°N.
