A meditation on Archimedes to satisfy the needy


Why Archimedes is Awesome

  • Started calculus
  • Made the best estimate of pi up to that time
  • Was completely in love with math


Archimedes has always been a figure who impressed and intrigued me. I got an opportunity in 11th grade to really explore him and that led me to writing an essay on him and the depth of his love of math. His life is a model of beautiful passion, something we are all capable of but which many of us are afraid to explore.

Eureka!

Few men have understood the glory of living. Thorton Wilder calls those few “poets and saints.” While not all poets and not all great men truly understand this glory, some understand and that is what compels them to do great things. They understand that every moment is worthwhile, that the grimmest part of life is still life and is still beautiful. Most will never have that understanding, most understand only after they can look back on their entire life, and that can only happen at death. “It takes life to love Life,” Edgar Lee Masters once wrote. And for most that is true, but for a very few, understanding comes naturally and it makes them glorious. One of these great men was Archimedes1 of Syracuse. He was an ancient Greek mathematician, considered to be one of the three greatest mathematicians of all time2 (Golba, online). He revolutionized math in the ancient world and his contributions directly inspired new discoveries more than a 1000 years after his death. The elegance and beauty of math and pure logic amazed him. He was always contemplating the magnifigance of the universe in his symbols and numbers. He loved truth, understanding, and figuring out things. Math was his passion and he served his passion well (O’Connor and Robertson, online). Archimedes will always be remembered, because he could connect a grain of sand with the universe, and figure the mind of God plus or minus a sin function. Archimedes understood the beauty of life and that made him a very great man.

Archimedes was born around the year 287 BC. His father, Phidias, was a Greek astronomer, and he raised him in a house of math (Bendick 1). His city was Syracuse, a major city on Sicily, and a bustling seaport. He was likely related to the king of Syracuse, King Hiero II (Rorres, online). This suggests that he was moderately wealthy and so it’s not surprising he had enough to travel to Alexandria to study math in all its shapes and forms (Bendick 24). Math as a science was just beginning (Benedick 16). However, it was growing and mathematicians were gathering their information together in Alexandria; thus started for the first time a mathematical community (Bendick 26). Archimedes joined this community and dug in to every field he could. This was the beginning of Archimedes’ long and amazing career in math. He began sending out work to his colleages and gained a reputation for being top-notch. He eventually left Alexandria, leaving behind a considerable legacy including the Archimedes screw, an irrigation device (O’Connor and Robertson, online). He returned to Syracuse, but his math work did not stop. He became an expert engineer, revolutionizing the field of the lever, creating pulleys upon pulleys upon pulleys, and building some of the largest catapults the world had ever seen. He even once created, some say, a reflective mirror that burned enemy ships (Rorres, online). Most of his inventions went straight to the war room where King Hiero and his successors used them in Syracuse’s ongoing wars with Rome, a power just beginning to bloom (Golba, online). Archimedes’ inventions3 saved Syracuse the initially from a powerful seige, but Syracuse was taken by a suprise attack by Rome and was conquered (Rorres, online). Archimedes died when Rome took over Syracuse, killed by a soldier, despite orders that said to spare the mathematician’s life (Bendick 128).

While Archimedes was known for his inventions, that wasn’t his field of choice (Golba, online). His greatest works were in the fields of arithmetic, geometry, and physics. Nine of his works have survived, On plane equilibriums (two books), Quadrature of the parabola, On the sphere and cylinder4 (two books), On spirals, On conoids and spheroids, On floating bodies (two books), Measurement of a circle5, The Method, and The Sandreckoner. It is known that he did much more; his name is used in many, many works of his contemporaries and his successors. He developed the basis of integral calculus, he examined every geometric shape from the spiral to the circle. And yet Archimedes also treasured the ideas of others, using some of the newest of the time, like the sun-centered universe6 (O’Connor and Robertson, online). He loved ideas and the truth. Archimedes went far beyond just proving new math to be true, he wrote his methods down for the ages, and he also invented a new numeral system to express numbers that Greek numerals couldn’t. This number system came in handy when Archimedes calculated the number of sands of grain needed to fill the universe7, or at least the concept of the universe at the time (O’Connor and Benedict, online). This was not practical but it was a work of love, for Archimedes truly treasured the order and logic of the universe through math.

Archimedes’ art was math and he loved his art. Yet math is not an art of creation, it is an art of discovery. The laws of math have been true since the beginning of existence and Archimedes reveled in them. He would go without eating, start scribbling while bathing, writing down math as fast as he could. If he could ever find a surface to draw upon, even if it was simply the dirt with a twig he would start drawing figures (Golba, online). In the end these figures led to his death. Accounts of his death8 claim that he was scribbling math in the dust during the invasion of Syracuse when he was confronted by a Roman soldier, he told the soldier “don’t disturb my figures” and the enraged soldier killed him (Rorres, online). Archimedes was in such rapture about the joys of discovering new truth that he did not noticed the burning of his city around him. He did love his city and gave it some of his finest inventions, but math was his true love and so he could not waste time fretting over a city when the secrets of the universe were at stake. It was through this love that he loved life. He found that the universe had in it unlimited wonder and was continuously trying to find that wonder through math. His love of math was his love of life, his math was but an expression of life’s logic. Archimedes worked to his last moment, savoring every second, and then died forever a mathematician in love with the order of the universe.

Archimedes lived a life of math. Being a mathematician was nothing special especially with an astronomer for a father. Yet he is the greatest of all the mathematicians of antiquity, perhaps of all time. He figured out the relationship between the volumes of a sphere and a cylinder, he figured out the workings of water displacement, he understood the secrets of conics and a great deal more (Rorres, online). He was great, but what drove him was a love of math. This love of math was a forever wonder about the mysteries of life, and in this way Archimedes understood life.

1-Archimedes was his full name, most Greeks only had one name (Bendick 1)

2- The other two are Newton and Gauss (Golba online)

3-In addition to the inventions already mentioned Archimedes employed a large metal contraption that would rake ships at sea, he also booby traped the walls of Syracuse (Rorres, online)

4-This work concerned the ratio between the two and Archimedes requested that ratio be engraved on the door of his tomb (Golba, online)

5-In this book he calculated the most accurate pi at the time (Bendick 91)

6-Archimedes used the universe constructed by his father, Eudoxus, and Aristarchus, (O’Connor and Robertson, online). He later made a mechanical model of this universe that lasted 200 yr.s (Benedict 78)

7-the number of grains needed to fill the universe is approximately 8*10^16 (O’Connor and Robertson, online)

8-One account says he was carrying mathematical equiment that looked like gold and that is why he was killed (Rorres, online)

Let me hear you say math... MATH!!!

A friend of mine once noted that it's a shame that math theory is becoming too complicated for normal people to play with.

But I don't think that it's a necessity, I think mathematicians just accept that this is the way the world must be, and thus refuse to take any effort to simplify mathematical theory.

And perhaps more importantly, new areas in math theory which might be more accessible to amateur innovation aren't being explored as vigorously as they should, largely because mathematicians are starting to forget what math is really about...

Playing with numbers.

Because numbers rock.

In that spirit, look at a list of squares
1
4
9
16
25
...

If you look at the differences between consecutive squares, you'll see a pattern and if you play with that pattern a little, you get...

n^2 = Sum from i=1 to n (2i - 1).

Think about it...

Even Mathimoto Loves Quotes

Now man can subsist on Math alone, after all is not math the word of God?



(More or less)



But it does not harm things to check out the literate world, especially when it deals with Math. Now while I may have recommended you, my dear readers, to this site before, I'd like to make a second strong recommendation for the site, the site with the might of what's right:



Professor Matthias Beck's Mathematical Quotes Page!!!



And let me share with you a couple of the highlights:



"It is my experience that proofs involving matrices can be shortened by 50% if one throws the matrices out."

"If things are nice there is probably a good reason why they are nice: and if you do not know at least one reason for this good fortune, then you still have work to do."

Richard Askey (Ramanujan and Important Formulas, p. 32, in Srinivasa Ramanujan (1887-1920), a Tribute, K.R. Nagarajan and T. Soundarajan, eds., Madurai Kamaraj University, 1987)



"Quapropter bono christiano, sive mathematici, sive quilibet impie divinantium, maxime dicentes vera, cavendi sunt, ne consortio daemoniorum animam deceptam, pacto quodam societatis irretiant."

("Thus the good christian should beware of mathematicians and all those who make false prophecies, however much they may in fact speak the truth; lest, being in league with the devil, they may deceive errant souls into making common cause.")

Augustinus (De genesis ad literam, Liber 2, Caput XVII, Nr. 37)



"If a 'religion' is defined to be a system of ideas that contains unprovable statements, then Gödel taught us that mathematics is not only a religion, it is the only religion that can prove itself to be one."

John Barrow



"Obvious is the most dangerous word in mathematics."

E. T. Bell



"Mathematics is a collection of cheap tricks and dirty jokes."

Lipman Bers



"We all agree that your theory is crazy, but is it crazy enough?"

Niels Bohr (1885-1962)



"5 out of 4 people have trouble with fractions."

Board in Danby, NY



"There are three kinds of people: those who can count and those who can't."

"The essense of mathematics resides in its freedom."

"To ask the right question is harder than to answer it."

G. Cantor



"Alice laughed: 'There's no use trying,' she said; 'one can't believe impossible things.' 'I daresay you haven't had much practice,' said the Queen. 'When I was younger, I always did it for half an hour a day. Why, sometimes I've believed as many as six impossible things before breakfast.' "

"Where shall I begin" he asked. "Begin at the beginning", the king said, "and stop when you get to an end."

L. Carroll (Alice in Wonderland)



"I'm a mathematical optimist: I deal only with positive integers."

"The hardest thing being with a mathematician is that they always have problems."

Tendai Chitewere



"I saw, as one might see the transit of Venus, a quantity passing through infinity and changing its sign from plus to minus. I saw exactly how it happened... but it was after dinner and I let it go."

Winston Churchill (My early life, 1930)



"The mathematical phenomenon always develops out of simple arithmetic, so useful in everyday life, out of numbers, those weapons of the gods: the gods are there, behind the wall, at play with numbers."

Le Corbusier



"A mathematician is a blind man in a dark room looking for a black cat which isn't there."

Charles R. Darwin



"The grand thing is to be able to reason backwards."

Arthur Conan Doyle (A study in scarlet)



"Apu: In fact I can recite pi to 40000 places. The last digit is one!

Homer: Mmmm, pie."

Ned: Nope, you will.

Homer: 'Fraid not.

Ned: 'Fraid so!

Homer: 'Fraid not.

Ned: 'Fraid so!

Homer: 'Fraid not infinity!

Ned: 'Fraid so infinity plus one!

Homer: D'oh!"



"Internet Guy: Your stock is at zero.

Bart: But I have 52 million shares! What's 52 million times zero?! And don't tell me it's zero!"

"(Homer has disappeared into a wall in the living room.)

Lisa: Well, where's my dad?

Frink: Well, it should be obvious to even the most dimwitted individual who holds an advanced degree in hyperbolic topology, n'gee, that Homer Simpson has stumbled into...[the lights go off] the third dimension.

Lisa: [flips the light switch back] Sorry.

Frink: [drawing on a blackboard] Here is an ordinary square....

Wiggum: Whoa, whoa--slow down, egghead!

Frink: ... but suppose we extend the square beyond the two dimensions of our universe, along the hypothetical z-axis, there.

Everyone: [gasps]

Frink: This forms a three-dimensional object known as a "cube," or a "Frinkahedron" in honor of its discoverer, n'hey, n'hey.

Homer's voice: Help me! Are you helping me, or are you going on and on?

Frink: Oh, right. And, of course, within, we find the doomed individual."
