Julius Caesar (c. July 12 or 13, 100 BC to March 15, 44 BC) was a politically adept and popular leader of the Roman Republic who significantly transformed what became known as the Roman Empire by greatly expanding its geographic reach and establishing its imperial system. Allegedly a descendant of Trojan prince Aeneas, Caesar’s birth marked the beginning of a new chapter in Roman history. By age 31, Caesar had fought in several wars and become involved in Roman politics. After several alliances, he became dictator of the Roman Empire, a rule that lasted for just one year before his death.
Only 70 percent of the world’s snakes lay eggs. The rest give birth to live young. Oviparous—or egg-laying—snakes tend to live in warmer climates, which helps incubate their eggs. Viviparous—or live-birthing—snakes tend to live in cooler regions, where the ground is too cold for the eggs to develop on their own.
Pig bladders were used in the 19th century to store an artist’s paint. The bladder would be sealed with a string and then pricked to get the paint out. This option wasn’t the best because it would often break open. American painter John G. Rand was the innovator who made paint tubes from tin and screw cap in the 19th century.
