Things That Archimedes Made
Following in the footsteps of other great eccentric Greek mathematicians, Archimedes seems to have gone about his life by trying to learn something new every day. To make an exhaustive list of everything he discovered, invented, or improved would take far more space than what should be contained in these virtual pages, so today we'll take a look at just a few of his mind-boggling creations.
The pulley itself is so ancient that its creator's name has been lost in the mist of time. Archimedes experimented heavily with pulleys and created the world's first block and tackle system (basically a mechanism in which two or more pulleys are utilized). He discovered that each pulley he added made the load seem lighter, since the force was being transferred equally among all the pulleys in the array. This allowed merchants to construct great cranes capable of lifting heavier cargo, which meant more money on arrival.
But his genius did not end at maritime physics. While trying to find an easier way to irrigate highland farms, he invented Archimedes' screw, a device capable of carrying water upward. Now, ground water could be raised to the surface and reused on the crops. It could even be carried up mountains, if the pipes and screws were long enough. This revolutionary invention was so useful that the Romans later built it into all their farmland and even used it to carry drinking water into high fortified camps. Here's a great image of how this works:
During the First Punic War, he invented a primitive odometer. It was an array of gears and levers which would drop a ball into a small box for each mile it traveled. To have done this during a time when people believed that disease was caused by the moon is not only surprising; it's mind-bogglingly astonishing. In addition to this, he created several astronomical implements, some of which were carried away as loot by the Roman commander who sacked Syracuse.
In between revolutionary and brilliant inventions, he did Calculus. But wait! Didn't Sir Isaac Newton invent Calculus? No more than Henry Ford invented the automobile. Newton greatly expanded the science, which laid dormant for more than a thousand years, but it was Archimedes himself who made the first foray into the measurement of the infinite. Unfortunately, there was no one around capable of understanding Archimedes' work, let alone carry it on. Though he served as a bright light for a time, the world went dark again at his passing, and the Greeks and Romans went back to their day-to-day business, being afraid of things they didn't understand. His work lives on, and he remains one of the most important mathematicians and inventors in all of history.

The Siege of Syracuse
Located in south-eastern Sicily, Syracuse was an old Corinthian-Greek Colony with old-time values. Ruled over by kings and tyrants since its founding in 733 BCE, Syracuse enjoyed the many benefits of its central Mediterranean locale and became very wealthy through trade with Egypt, Rome, Carthage, Asia Minor, Palestine, and Spain. After the Pyrrhic war in 275 BCE, however, it was the sole remaining Greek settlement west of the Peninsula itself, and in a very tenuous position sandwiched between Rome and Carthage.
Syracuse survived for quite a while after Pyrrhus' final defeat because its leaders made smart alliances and used skilled diplomacy to ensure the protection of either Rome or Carthage. When the first Punic War broke out, Syracuse was at the center of the action and made an alliance with Carthage from fear of Rome. Luckily, Rome and Carthage fought each other so bitterly that by the time Rome got around to dealing with the unlucky Sicilian Greeks, they had already lost so many in battle that they were willing to settle for an apology and a cut of their trade. However, when the second Punic War broke out, Syracuse made the mistake of allying with Carthage again, and the Romans were determined to make them pay. However, Roman vengeance would come at a high cost to the Republic because of one resident of Syracuse whose mind possessed knowledge that could bring both great prosperity and very great destruction. This man's name was Archimedes.
I like to think of Archimedes as a sort of ancient world Da Vinci, except without the moral qualms about creating weapons. Where Da Vinci was purposefully putting gears in the wrong place so that his designs would ultimately fail, Archimedes was not only sketching these out, but utilizing them to a terrible degree of success. For this week's Famous Friday, we'll delve into Archimedes' discoveries in greater detail, but since it's Military Monday, let's focus on his original and horrific siege weapons.
The most famous of his weapons was The Claw, which utilized pulleys and complicated weight balancing to capsize Roman Triremes. Seriously, this crane-like weapon would hook onto the bow or stern of the boat, lift it out of the water, and send it crashing against the nearby rocks. Each boat carried about two hundred soldiers, so you can imagine the carnage that ensued when this happened over and over:
Another of his creations was an improved catapult. Again, using pulleys and counterweights, he was able to create an engine capable of throwing a 500 pound rock with much better accuracy than the inferior Roman scorpions and ballistae. He also contributed to the building of other weapons which could fire missiles and keep the Romans at bay.
The most controversial of his creations was his 'death ray.' Several authorities have tested it using various techniques, and some have been successful, while most have ended in a wash. Supposedly, Archimedes built a large array of bronze mirrors which could be turned, focusing their reflected light into a concentrated beam onto an approaching ship. The Roman ships, which were sealed with tar, caught on fire and sunk. While this does seem a bit far-fetched, I wouldn't put it past old Archie to give it a try. After all, it was Hiero II, the king of Syracuse and relative of Archimedes, who frequently challenged the genius and gave him the funding he needed to build better weapons since the first Punic War, so why wouldn't this mathematician try literally everything he could think of? Were there easier ways to light ships on fire? Yeah, lots. But if I were an invading Roman, I might think twice about mixing it up with an enemy who can light my ships on fire without shooting anything.
Syracuse eventually fell to sheer Roman determination, and Archimedes was killed, possibly while drawing circles in the sand. If not for him, the last Greek colony on Italian soil would surely have fallen in the first year, and Carthage wouldn't have stood a chance of surviving the Second Punic War. By the time the Roman army came to the gates of Carthage, they had suffered so many casualties from Syracuse and from fighting Hannibal for ten years that they allowed Carthage to live, albeit under severe economic sanctions. And when Carthage was finally leveled in the Third Punic War, there were no more brilliant mathematicians around to set Romans on fire from a distance.

Bonus Post: Tiberius' Farming Reforms
On an unrelated note, next week will be Archimedes week, for no reason in particular. Every day we will learn more about this famous mathematician who would move the world if he only had a place to stand.
