A Popthem is an insight. It comes from the word apothegm - a comment, an anecdote, a statement - something that turns on that light bulb in your brain and makes you think - "so that's what really happened", or "so that's what it means". It's stuff we've read that we found illuminating and that we want to share with others by posting on this blog. See Leondardoswall.com for the latest in how Leondardo Da Vinci got his ideas.

Columbus' Egg and Facebook
POP1
Columbus' Egg refers to a brilliant idea or discovery that seems simple or easy after the fact.
Italian historian and traveler Girolamo Benzoni in his book 'History of the New World', published in 1565, wrote that Columbus was dining with a number of Spanish nobles when one of them said: "Sir Christopher, even if your lordship had not discovered the Indies, there would have been someone else here in Spain, which is a country abundant with great men versed in cosmography and literature, who would have started a similar adventure with the same result."
Columbus did not respond to these words but asked for an egg to be brought to him. He placed the egg on the table and said: "I will lay a wager with any of you that none among you is able to make this egg stand on its end, which I will do without any kind of help or aid." They all tried without success. When the egg returned to Columbus, he tapped it gently on the table to flatten the tip slightly and so stood it on its end. All those present understood what he meant - once the feat has been done, anyone knows how to do it.
POP2
According to Vasari (a chronicler of Renaissance artists), the young Italian architect Filippo Brunelleschi had designed an unusually large and heavy dome for Santa Maria del Fiore, the new cathedral of Florence. City officials had asked to see his model, but he refused.
Instead he proposed that anyone who could make an egg stand upright on a flat piece of marble should build the cupola, since in this way a man's intellect would be revealed. None was able to accomplish the feat. Whereupon Filippo was told to make it stand. He took the egg graciously and gave one end of it a blow on the flat piece of marble, thus making it stand upright.
The craftsmen protested that they could have done the same. Filippo answered, laughing, that they could also raise the cupola, if they saw the model or the design. And so the decision was made to give Brunelleschi the commission to carry out the construction of the dome.
When the Duomo was finally built it had the shape of half an egg slightly flattened at the top.
The concept of this story is a little different from Columbus' Egg, for that was a metaphor for those acts of creativity that give everybody 20/20 hindsight after the fact; the Brunelleschi story is more of an intellectual conundrum since his plan had not yet been revealed.
It is possible that Columbus, being Italian, had read the Vasari story, whereas the Spanish Grandees were not aware of it.
POP3
What could be more obvious than a website that would function like a private house where friends gather to talk in private, and invite other friends, and share photos, ideas, opinions etc.
But no-one did it till that guy from Harvard came up with Facebook - Columbus' Golden Egg.
POP4
If the story of Columbus' Egg says anything, it's this - the mark of a creative mind is an ability to see the obvious.

Farmers and The Magnificent Seven.
POP1
Dialogue about peasants (farmers), from The Magnificent Seven:
"They are afraid of everyone and everything.
They are afraid of rain, and no rain...
The summer may be too hot, the winter - too cold.
The sow has no pigs, the farmer is afraid he may starve.
She has too many, he's afraid she may starve."
POP1
The farmers across the midwest were complaining that this would be a terrible year for them because of the extended drought - all the worse because the early spring had raised hopes of a banner year, and they had over planted accordingly.
Amazingly, after all the complaining about the heat and lack of rain, this year (2012) may not be so bad.
POP2
There's no question there will be less corn for sale than expected in the U.S. this year. But here's the rub - it's driven grain prices to record levels.
The U.S. Department of Agriculture said despite the current drought, it predicts net farm income will rise 3.7 percent this year to more than $122 billion, as high grain prices offset loss of production.
Most grain and oil seed farmers have taxpayer-subsidized crop insurance which will cover, on average, 70–80 percent of their loss of "average production." It is also becoming apparent that most farmers will still have some corn they can sell at top prices, if they haven't pre-contracted too much of it back when corn was $5 a bushel instead of $8, and provided they made the decision to buy crop insurance - it's a free country, and it's their choice, but they could complain that they made the wrong choice
POP3
In fact, some farmers will make more money this year having crop insurance than they would have if there was a normal yield because they planted so many corn acres.
Surely someone's got to get hurt. Possibly the livestock producers because of the high cost of corn. And so it goes on - unless there's still another angle to this.
And then there are the insurers, which includes the federal government, which means taxpayers like you or me. We should be the ones complaining. We're the peasants from The Magnificent Seven.
POP4
It seems someone always benefits from a drought. Remember the movie Chinatown. There's a drought in Los Angeles sometime in the thirties. The sheep farmers certainly aren't benefiting, as is made clear at the beginning of the movie when a flock of sheep is herded into the city water department meeting in protest.
Turns out it's Noah Cross, (played by John Huston), who's going to benefit. He's been buying up land in the Valley at daylight robbery prices driven down by the drought; and while he has been siphoning off city water to irrigate his orange groves, he's been depriving the other landowners of water so that he can buy their land cheap. Too far fetched?, or not.

Victorian Bodybuilding (Lack of).
Members of Brighton Swimming Club, England 1863.
POP1
1863, the middle of the American Civil War. That gives an idea of the time period of the photograph. Note the physiques. No six-packs. Bodybuilding was not part of the health club culture of Victorian England. Yet this was the England that was building an empire as large as that of Genghis Khan, and sending out young men like these to administer the vast domains.
POP2
From the top hats that they are wearing, they appear to belong to the upper classes. The working classes, who do not appear to have been invited to participate in the activities of the Brighton Swimming Club, may well have had more solid physiques. But just as Theodore Roosevelt writes in his "The Winning of the West: The spread of English-speaking peoples", the American frontiersman was seldom a match for the Indian in a one to one fight; so the English soldier, whichever class he came from, would seldom have been a match for a Zulu warrior. But that is not what colonial warfare was about. It was about firepower and military discipline, and character.
POP3
Victorian England was the age of the cold showers as a way of building character. Even the Prime Minister of England, Benjamin Disraeli, was not immune to the cold shower craze; but he had a hard time pulling the trigger, and while he stood apprehensively under the shower, it devolved on his wife to actually turn on the cold water.

USS Constitution ("Old Ironsides") and Guerriere. Was it a fair fight?
POP1
The sea battle between the USS Constitution and the HMS Guerriere occurred 19 August 1812, exactly 200 years ago. It was a great morale booster for the young American republic, occurring so soon after America became independent of Britain.
But was it a fair fight?
POP1
The sea battle between the USS Constitution and the HMS Guerriere occurred 19 August 1812, exactly 200 years ago. It was a great morale booster for the young American republic, occurring so soon after America became independent of Britain.
But was it a fair fight?
POP1
Compare the size and armament of the respective ships.
The Constitution was 1576 tons and carried 44 guns with 950lb of broadside (ammunition). The Guerriere was 1092 tons and was rated as 38 guns, with 526lb of broadside.
The Constitution had a complement of roughly 450 including 55 Marines and 30 boys, as compared to the Guerriere's 272.
The Constitution's 24-pound cannonballs felled the Guerriere's mast, which turned the British ship into a sitting duck; while the British vessels' 18-pound cannonballs had trouble penetrating the Constitution's hull.
It doesn't look like a very equal struggle. However Britain had been waging war with France for some nine years and British ships had considerably more experience of sea warfare than the Americans. Despite the diference in size and armament of the respective frigates, the British captain considered it an equal struggle ; accordingly, it was a traumatic defeat for British sea power.
But here's the kicker:
POP3
A sailor's memoirs of the struggle record how one cannonball seemed to slightly penetrate the ship, before dropping into the sea. The sailor then called out the quote that would give the Constitution its nickname, "Huzzah, her sides are made of iron! See where the shot fell out!"
The hull of the "USS Constitution" was made of Georgia live oak sandwiched between two layers of white oak, and was 21 inches thick. The Guerriere had been built in France, using European oak of poorer quality than the Georgia oak, which tipped the scale of the conflict in favor of the American.
It was a tradition that when a ship was captured in battle, it would retain the name it had before the capture. The British navy had captured the Guerriere from the French. It never became an American vessel because it burned and sank immediately after the battle with USS Constitution.

Rebellion in Syria. Father's Love
POP1
TAL RIFAAT, Syria — Abdul Hakim Yasin, the commander of a Syrian antigovernment fighting group, 37, had been a clean-shaven accountant before the war. He had lived a quiet life with his wife and two young sons. Now he had a thick beard. The war had hardened him.
In July, his father, Jamal, had been arrested by the soldiers. He suspected it was because the government knew his son led an armed group; he said he expected his father would be killed.
His father had just called to say his jailers had released him and he needed a ride out of Aleppo.
Abdul Yasin shouted that his father had called and said he had been unexpectedly let out from prison. They needed to rush to retrieve him. The rebels climbed onto trucks, loaded weapons and drove on nearly deserted roads toward a city under siege, to reclaim their leaders father.
POP2
Mr. Yasin was pensive as he drove, worried that the call was a ploy to lure him and his fighters into a trap.
In the lead truck, Mr. Yasin repeatedly tried to call a friend he had sent ahead in civilian clothes in an empty freight truck. He was expecting a trick, and wanted the lead driver to ensure that his father actually was free and there was no trap. Then the fighters could drive in.
At the outskirts of the city, he reached the other man, who reported that he was with Jamal Yasin, driving north.
In the darkness of the abandoned road, the other truck approached and stopped. Jamal Yasin (Abdul's father) climbed out.
Jamal Yasin said he had not been tortured. But the prison cell was tiny and so overcrowded that he almost could not sleep.
Abdul Hakim Yasin admitted to his worry. “I was 99 percent sure it was an ambush,” he said.
POP3
His father listened, then gently admonished his son. “You really think if it was an ambush I would call you?” he said. “Even if they were slitting my throat?”

Montaigne and Glory. Death in a ditch.
Montaigne's tower, in which he wrote his 'Essays' |
POP1
Glory in battle. It's all about luck. To what do Caesar and Alexander owe the infinite grandeur of their renown if not to luck. How many men has fortune extinguished in their first encounter with battle, at the very beginning their life's journey. Yet through so many great dangers that he encountered Caesar was never wounded; whereas a thousand have fallen in lesser dangers than the least of those he went through.
POP2
Men do not write histories of things of little moment, of the things that happen to the common soldier.
A man must have been a general in the conquest of an empire or a kingdom; he must have won two-and-fifty set battles, (and always outnumbered), as Caesar did. Ten thousand brave fellows and many great captains lost their lives valiantly in his service, whose names lasted no longer than their wives and children lived.
"When beggars die there are no comets seen.
The heavens themselves blaze forth the death of princes."
(Julius Caesar, Shakespeare)
POP3
To gain renown in battle, a man must be seen to do great deeds; but the fact is he is not always on the top of a breach, or at the forefront of an army, where his general can see him, as if he were an actor on a stage.
Reality is different.
A man is often surprised between the hedge and the ditch; he must run the hazard of his life against a hen roost; he must root out four paltry musketeers from a barn; he must go out alone from his company, and do his job as the need arises. And whoever will observe will find it true by experience, that occasions that are the least brilliant are ever the most dangerous; and that in the wars of our own times there have been more brave men lost in trivial, unimportant occasions, fighting over some little shack, than in places of greatest importance, and where their valour might have been more honourably employed.
So that's the nitty-gritty of battle in France in the 1500's - an inglorious and unseen fight to the death, between a hedge and a ditch.
From Montaigne's essays.

Cinderford. 1943. Mustard Gas.
Under a forest canopy.
POP1
The debate between Roosevelt and Churchill on the subject of whether to use Nerve gas lasted throughout the war. Roosevelt was opposed, and in June 1943 he sharply reaffirmed United States policy on gas warfare: "Use of such weapons has been outlawed by the general opinion of civilized mankind. This country has not used them, and I hope we will never be compelled to use them. I state categorically that we shall under no circumstances resort to the use of such weapons unless they are first used by our enemies."
POP2
Nevertheless, in 1942 the Army's Chemical Warfare Service (CWS) received one billion dollars and had more then sixty thousand employees. Its tasks included preparing for gas and bacteriological warfare, as well as producing incendiaries for bombing, flame throwers, and other devices.
POP3
In December 1943, after the bloody Battle of Tarawa, which had cost the United States more than thirty-four hundred casualties in four days, the chief of the CWS pleaded with Army superiors to start using gas. He argued that in view of american air superiority, there would be no danger of reprisals.
There was some popular support for this view. The New York Daily News declared , "We should gas Japan". The Washington Times Herald asserted, "We should have used gas at Tarawa" because "You can cook 'em better with gas". But this was a minority opinion. About 75 percent of Americans still opposed initiating gas weapons.
It was on military grounds, not moral, that the Army decided against their use. The argument that won favor was that this was a two-theater war, and the use of gas against Japan might provoke Germany "To gas in retaliation."
POP4
About a week after D-day, Germany launched a massive V-1 rocket assault on Britain, killing twenty-seven hundred people, injuring ten thousand, and damaging the homes of more than two hundred thousand. Eager to punish Germany and hoping likewise to deter future rocket attacks, Churchill wanted to "drench the cities of the Ruhr and many other cities in Germany (with gas) so that most of the population would be in constant need of medical attention".
Churchill informed his military advisers: "It is absurd to consider morality on this topic when everybody used it in the last war without a word of complaint from the moralists or the Church. On the other hand, in the last war the bombing of open cities was regarded as forbidden. Now everybody does it as a matter of course. It is simply a question of fashion changing as she does between long and short skirts for women."
But not yet quite ready to cross what many considered a moral threshold, he qualified his statement indicating that he would use gas only if "it (is) life or death for us, or (if) it would shorten the war by a year."
Note on the Battle of Tarawa: There were between 10,000 and 12,000 casualties out of 160,000 troops landed on the Normandy beaches on D-Day,
He directed his military advisors to come up with a "cold-blooded calculation as to how it would pay us to use poison gas...I want the matter studied in cold blood by sensible people and not by that particular set psalm-singing uniformed defeatists which one runs across now here now there'
Disappointingly for Churchill, his advisors argued that aircraft would be diverted from their more effective utilization in bombing Germany's industries and cities.
POP5
In 1945 as the war in Europe was winding down, General Marshall, the Army Chief of Staff, wanted to initiate gas warfare against Japan. British opposition prevented him. It was feared that Germany, involved now in the last few weeks of the war, might be tempted to resort to gas in Europe.
POP6
After the War, it was revealed that the United States had produced 135,000 tons of chemical warfare agents, Germany about 70,000 tons, Britain 40,000 tons, and Japan had 7,500 tons.
