Archimedes' Death Ray

When I heard of Archimedes’ Death Ray, the name alone was enough to get me interested. Who could resist some thing called a Death Ray?? After some investigation, I learned that this story dates back to the Second Punic War. According to Greek and Roman historians, when, in 212 BC, Syracuse faced an attack from the Romans, they turned to Archimedes, the great (and local) physicist, mathematician, and engineer, for defense. According to the story, he developed his Death Ray as a means of halting the approaching Roman naval fleet. Archimedes instructed the soldiers of Syracuse to polish their shields until they shone like mirrors. They were then positioned along the coast of the island, facing the incoming Roman navy. The sun was reflected off of the many shields onto Roman ships, causing them to burst into flames and thus ending the Roman advance.

At first, I agreed with many scholars that the whole thing sounded a bit far-fetched. The idea of being able to burn up the Roman fleet like ants under a magnifying glass simply with polished shields seemed unbelievable. However, some experiments have been done that bring my initial doubt into question. An engineering class at MIT tested the ability of reflective metal shields to light wooden ships on fire. After a few tests, the engineers declared that it is, in fact, possible! Granted, the results were not perfect. The MIT students, for example, found that direct sunlight was necessary as the shields were highly responsive to even minimal cloud coverage. Nevertheless, they showed that it was indeed possible to ignite wood with nothing more than the sun and some highly reflective metal shields. The same group collaborated with the team from Discovery Channel’s Mythbusters to perform another test. They were unable to produce the flash ignition that the initial MIT team created, although there was some burning, eventually causing a 10 in. hole in the boat.

Surely, these test results cannot be taken to mean that the story of Archimedes is true. However, they have convinced me that the Death Ray is not out of the realm of possibility.

Give Me Liberty, or Give Me Death: The Melian Dialogue

In a class I am currently taking we were, in our study of Thucydides’ History of the Peloponnesian Wars, the Melian Dialogue (V: 84-116). This debate, between representatives of Athens and the council of Melos, takes place in 416 BC, right in the meat of the war. Melos, a small island city-state, while known as being sympathetic to Sparta, claimed neutrality in the war. (Recent evidence has suggested that at least some Melians did, in fact, pay tribute to Sparta. That can be looked into more in-depth later.) Athens, eager to secure all islands as allies in their domination of the seas, sailed to the island to demand their tribute, whether through debate or force. This dialogue consists basically of the Melians trying to convince the Athenians to let them remain neutral and the Athenians, in turn, demanding the Melians pay tribute and become their ally

In discussing this in class, I was shocked to discover that the vast majority of students, when polled, would have surrendered to the Athenians rather than fight had they been in the Melian council. I am certain that most, if not all of the students, were influenced by the outcome of the actual historical events – the Melians resisted and were eventually defeated; all the men were killed, the women and children sold into slavery, and their city repopulated by Athenians. Nevertheless, where was these students’ sense of pride and honor? Their respect for national freedom, even in the face of an overwhelming enemy? Especially in this classroom situation, where there is nothing really at stake, how could you not vote in favor of freedom??

This debate, and the hubris of the Athenians, reminded me of another similar historical event, one with a very different outcome. The American Revolution. True, there are some major differences; the American’s had no Sparta to fall back on, nor were the Melians a colony of Athens. However, the core of the Melians’ and Americans’ conundrum is the same: do you surrender to foreign rule in order to avoid destruction, or do you take up arms, despite a horribly unequal battle, to sacrifice everything to save your independence? When debating this issue from the Melians’ perspective, the phrase that I came back to again and again was one from Patrick Henry, “Give me liberty, or give me death.” I agree with the Melians. They had no choice but to fight. If freedom is not worth fighting for, what is? Henry would have agreed; “Is life so dear, or peace so sweet, as to be purchased at the price of chains and slavery?” The Melians clearly did not think so. If the they had just handed over their city, an independent polis built up over 700 years, to the first oppressor that came by, they would have been undoing all the hard work of their predecessors. They would be selling freedom at far too low of a price. The Melians affirm this position, stating “we who are still free would show ourselves great coward and weaklings if we failed to face everything than comes rather than submit to slavery” (V:100).

It unnerves me that my peers, representative, I fear, of my generation, were so unwilling to send our imaginary Melians into battle in the name of freedom. Are we too comfortable today, confident that the freedoms we enjoy in America are permanent? Do we take these for granted? I hope not. Freedoms are never for certain and we must always willing to fight for them, regardless of the costs. Because, in answer to Patrick Henry, I say that a life bought by chains and slavery is not one worth living.

Why study history?

Disclaimer: This title almost makes me laugh; it is so huge. Entire books have been written on this topic. I anticipate that I will return to it in future posts. So let’s think of this one as merely the first installment. Let’s go.

I have always heard that history repeats itself, as I am sure all of you have. This seemed for a long time as though it may be something that was really just meant to scare us. A phrase used by middle school teachers to make sure that their pesky little students were paying attention in class. Because if we didn’t, history teachers silently implied, we were all going to become the next Lost Generation of some terrible war or fall victim to another similarly devastating catastrophe that could have been avoided had only we listened in 7th grade World History. As time went on, I began to agree, however, that the study of history has very important implications in today’s world and that having the background and vocabulary of historical inquiry is essential for fully understanding something as seemingly simple as what’s in the newspaper on any given day. How are you to understand the current political situation in Russia without knowing the socialist past and subsequent downfall of the USSR? What previous wars and international relations can we look to in order to better understand what is the best next move for the U.S. in the Middle East? World affairs are just too complicated today to attempt to understand without at least some basic understanding of the history uniting and dividing various countries and region. I guess there was a reason I always had to do those weekly “Current Events” presentations in history class.

I have never, however, heard these concerns presented as eloquently and urgently as Thucydides in his History of the Peloponnesian War. Thucydides opens Book I by assessing his reasons for writing, sources, and methodology. It is in this section that he states:

"It will be enough for me, however, if these words of mine are judged useful by those who want to understand clearly the events which happened and which (human nature being what it is) will, at some time or an other and in much the same ways, be repeated." (I: 22 – Penguin Classics translation)

This seems to me enough motivation for studying history. Had the North and South looked closely at the events of the Peloponnesian War, would they have been more willing to compromise rather than launching into the Civil War? Would the story of these two neighbors and sometimes-allies, members, at one point, of the same league of city-states, have affected the Union or the Confederacy leaders? There are many lessons to be learned from the Peloponnesian War – the best and worst ways to treat both allies and enemies and the wrong way to offer negotiations, among a great number of other things. Would world history be different had our leaders studied to a greater extent the events of the past? I suppose no one can say for sure. But I, for one, most definitely agree with Thucydides that they would be – and for the better.
