Women in Science

This article by Philip Greenspun is about anyone in science (not just women), and suggests that it is a tougher road than even those who champion it as a career would suspect.

Quote of the day -- Calvin Trillin

"When I'm trying to impress Alice, for instance, I remind her that I have resolutely ignored drinking fashions for twenty-five years, steadily knocking back Scotch whiskey the entire time. They turned to wine; I drank Scotch. They smoked pot; I drank Scotch. They ordered Perrier water; I drank Scotch. They snorted cocaine while naked in a hot tub discussing real estate; I drank Scotch. I like to think that late on some Saturday nights Alice can point to me - slumped in the corner, sodden with scotch - and say, 'There sits a man of principle. Inert.'"

The Status Game

An interesting thought experiment, or possibly a provocative class exercise:

A stack of card was shuffled face down on a table, and each person was asked to choose a card without looking at it. Then the instructor asked us to get on stage, and raise our cards against our foreheads so that they are facing the rest of the group. Each person was automatically assigned a “status” corresponding to their card. Then the instructor suggested a business situation for us to enact in a way that helps each person guess the number on their forehead correctly. How would we do that? By changing our postures and tone of voice to match our estimated status and how it ranks against the status we see on other people’s forehead. For instance, if I am guessing the card on my head to be a 8, and I meet with a queen, I’d lower my voice and stand in a way that reflect the other person’s status dominance over mine. And if I meet a 5, I’d assume a higher posture and voice and may be give an order or two. If the person suddenly assumed a different posture and voice, it could mean that either she or I have the wrong guess. The goal wasn’t to challenge each other, but to help each other make the right guess.

Review of German Expressionist Art Exhibit




Walking through the German Expressionism exhibit really messed me up. All of them either killed themselves or fell down the stairs drunk to their deaths, and it was only, like, 1926, and you’re all ‘God, you have no fucking idea how much worse things are about to get, you poor people.’ The glorious shitshow of the 20th century has barely started, and you’re already painting elongated haunted torsos with exposed viscera.

Understanding Congress’s solution to the federal deficit problem

We have a family that is spending $38,200 per year. The family’s income is $21,700 per year. The family adds $16,500 in credit card debt every year in order to pay its bills. After a long and difficult debate among family members, keeping in mind that it was not going to be possible to borrow $16,500 every year forever, the parents and children agreed that a $380/year premium cable subscription could be terminated. So now the family will have to borrow only $16,120 per year.

The 'B' Students work for the 'C' students . . . .

America has made the mistake of letting the A student run things. It was A students who briefly took over the business world during the period of derivatives, credit swaps, and collateralized debt obligations. We’re still reeling from the effects. This is why good businessmen have always adhered to the maxim: “A students work for B students.” Or, as a businessman friend of mine put it, “B students work for C students—A students teach.”

Scientists answer Molyneux's question

It seems important any time scientists solve a question posed by philosophers hundreds of years ago.

Imagine, William Molyneux wrote to the great British thinker, that a man blind from birth who has learned to identify objects -- a sphere and a cube, for example -- only through his sense of touch is suddenly able to see.
The puzzle, he continued, is "Whether he Could, by his Sight, and before he touch them, know which is the Globe and which the Cube?"

For philosophers of the time, answering "Molyneux's question," as it was known ever after, would resolve a fundamental uncertainty about the human mind.

Empiricists believed that we are born blank slates, and become the sum total of our accumulated experience. So-called "nativists" countered that our minds are, from the outset, pre-stocked with ideas waiting to be activated by sight, sound and touch.

Dilbert Test for Gender Fairness


So I propose a simple test to determine if you, individually, are a victim of gender unfairness. If a genie gave you the chance to magically switch your gender, and become a member of the other sex, would you do it? And let's say the new you would be about the same as now on the scale of attractiveness, intelligence, ethnicity, circumstance, and health. The only real change would be gender. Do you take the offer?

Graphic Novel Biography of Hunter S. Thompson



From BoingBoing.

When Do You Hold The Bus?

The great football coach John Madden was once asked whether or not he would tolerate a player like Terrell Owens on his team. Owens was both one of the most talented players in the game and one of the biggest jerks. Madden answered:

“If you hold the bus for everyone on the team, then you’ll be so late that you’ll miss the game, so you can’t do that. The bus must leave on time. However, sometimes you’ll have a player that’s so good that you hold the bus for him, but only him.”

Phil Jackson, the basketball coach who has won the most NBA championships, was once asked about his famously flakey superstar Dennis Rodman: “Since Dennis Rodman is allowed to miss practice, does this mean other star players like Michael Jordan and Scottie Pippen can miss practice too?” Jackson replied:

“Of course not. There is only room for one Dennis Rodman on this team. In fact, you really can only have a very few Dennis Rodmans in society as a whole; otherwise, we would degenerate into anarchy.”

You may find yourself with an employee who fits one of the above descriptions, but nonetheless makes a massive positive contribution to the company. You may decide that you will personally mitigate the employee’s negative attributes and keep them from polluting the overall company culture. That’s fine, but remember: you can only hold the bus for her.

Hiding Gold Nobel Prizes in Plain Sight

When Nazi Germany invaded Denmark in World War II, the Hungarian chemist George de Hevesy dissolved the gold Nobel Prizes of the German physicists Max von Laue and James Franck in aqua regia to prevent the Nazis from confiscating them. The Nazi government had prohibited Germans from accepting or keeping any Nobel Prize after the jailed peace activist Carl von Ossietzky had received the Nobel Peace Prize in 1935. De Hevesy placed the resulting solution on a shelf in his laboratory at the Niels Bohr Institute. It was subsequently ignored by the Nazis who thought the jar—one of perhaps hundreds on the shelving—contained common chemicals. After the war, de Hevesy returned to find the solution undisturbed and precipitated the gold out of the acid. The gold was returned to the Royal Swedish Academy of Sciences and the Nobel Foundation who recast the medals and again presented them to Laue and Franck.

Buxton Index



From On the fact that the Atlantic Ocean has two sides by E.W. Dijkstra. (Photo of Dijkstra from Wikipedia article)


 A very useful measure is —called after its inventor— the "Buxton Index". John N. Buxton discovered that the most important one-dimensional scale along which persons are institutions to be compared, can be placed is the length of the period of time in the future for which a person or institution plans. This period, measured in years, gives the Buxton Index. For the little shopkeeper around the corner the Buxton Index is three-quarter, for a true Christian it is infinite, we marry with one near fifty, most larger companies have one of about five, most scientist have one between two and ten. (For a scientist it is hard to have a larger one: the future then becomes so hazy, that effective planning becomes an illusion.)

Burning Platform Memo from Nokia CEO

There is a pertinent story about a man who was working on an oil platform in the North Sea. He woke up one night from a loud explosion, which suddenly set his entire oil platform on fire. In mere moments, he was surrounded by flames. Through the smoke and heat, he barely made his way out of the chaos to the platform's edge. When he looked down over the edge, all he could see were the dark, cold, foreboding Atlantic waters.

As the fire approached him, the man had mere seconds to react. He could stand on the platform, and inevitably be consumed by the burning flames. Or, he could plunge 30 meters in to the freezing waters. The man was standing upon a "burning platform," and he needed to make a choice.

He decided to jump. It was unexpected. In ordinary circumstances, the man would never consider plunging into icy waters. But these were not ordinary times - his platform was on fire. The man survived the fall and the waters. After he was rescued, he noted that a "burning platform" caused a radical change in his behaviour.

We too, are standing on a "burning platform," and we must decide how we are going to change our behaviour.

The article starts with a wonderful quote on the importance of education from James Madison:

"A popular government without popular information, or the means of acquiring it, is but a prologue to a farce or a tragedy, or perhaps both. Knowledge will forever govern ignorance, and a people who mean to be their own governors must arm themselves with the power which knowledge gives."

Not clear whether he sketched them, or whether they were just illustrations he included in a folio of his other astronomical work.

"In either case, it is rather beautiful. But it didn’t seem that way to many people at the time. It was a shock and an affront to suggest that God’s heavenly objects were not perfect but pocked and roughened with craters and protuberances like some ordinary rock of the earthly realm. This would all come to a head when Galileo visited the pope in 1616 …"

Winter Solstice Eclipse tonight

The full moon will pass through Earth's shadow, changing from gray to a rusty, red color.

Why red? NASA describes it this way:

A quick trip to the Moon provides the answer: Imagine yourself standing on a dusty lunar plain looking up at the sky. Overhead hangs Earth, nightside down, completely hiding the sun behind it. The eclipse is underway. You might expect Earth seen in this way to be utterly dark, but it's not. The rim of the planet is on fire! As you scan your eye around Earth's circumference, you're seeing every sunrise and every sunset in the world, all of them, all at once. This incredible light beams into the heart of Earth's shadow, filling it with a coppery glow and transforming the Moon into a great red orb.

If you're not much for staring at the sky, at least glance up once: early Tuesday morning at 12:17 a.m. That's when the eclipse will be most striking, according to astronomers.

Prevention may not be a good way to reduce overall health care costs

Paper's conclusion: Although effective obesity prevention leads to a decrease in costs of obesity-related diseases, this decrease is offset by cost increases due to diseases unrelated to obesity in life-years gained. Obesity prevention may be an important and cost-effective way of improving public health, but it is not a cure for increasing health expenditures.

Battle Hymn of the Republic

Essay via The Atlantic on the history of the hymn, including alternate lyrics from the labor movement entitled Solidarity Forever.

The Battle Hymn of the Republic
by Julia Ward Howe

Mine eyes have seen the glory of the coming of the Lord:
He is trampling out the vintage where the grapes of wrath are stored;
He hath loosed the fateful lightning of His terrible swift sword:
His truth is marching on.

I have seen Him in the watch-fires of a hundred circling camps,
They have builded Him an altar in the evening dews and damps;
I can read His righteous sentence by the dim and flaring lamps:
His day is marching on.

I have read a fiery gospel writ in burnished rows of steel:
"As ye deal with my contemners, so with you my grace shall deal;
Let the Hero, born of woman, crush the serpent with his heel,
Since God is marching on."

He has sounded forth the trumpet that shall never call retreat;
He is sifting out the hearts of men before His judgment-seat:
Oh, be swift, my soul, to answer Him! be jubilant, my feet!
Our God is marching on.

In the beauty of the lilies Christ was born across the sea,
With a glory in his bosom that transfigures you and me:
As he died to make men holy, let us die to make men free,
While God is marching on.


Lyrics to Solidarity Forever:

When the Union's inspiration
Through the worker's blood shall run,
There can be no power greater
Anywhere beneath the sun,
Yet what force on earth is weaker
Than the feeble strength of one?
But the Union makes us strong.
Chorus:
|: Solidarity forever! :|
Solidarity forever!
For the Union makes us strong.
2. Is there aught we hold in common
With the greedy parasite
Who would lash us into serfdom
And would crush us with his might?
Is there anything left for us
But to organize and fight?
For the Union makes us strong.
Chorus:

3. It is we who plowed the prairies;
Built the cities where they trade,
Dug the mines and built the workshops;
Endless miles of railroad laid.
Now we stand, outcast and starving,
'Mid the wonders we have made;
But the Union makes us strong.
Chorus:

4. All the world that's owned by idle drones,
Is ours and ours alone.
We have laid the wide foundations;
Built it skywards, stone by stone.
It is ours, and not to slave in,
But to master and to own,
While the Union makes us strong.
Chorus:
5. They have taken untold millions
That they never toiled to earn.
But without our brain and muscle
Not a single wheel can turn.
We can break their haughty power;
Gain our freedom, when we learn
That the Union makes us strong.
Chorus:

6. In our hands is placed a pot
Greater than their hoarded gold;
Greater than the might of armies,
Magnified a thousand fold.
We can bring to birth the new world
From the ashes of the old,
For the Union makes us strong.
Chorus:

Advice to the Obama Administration

“You should stop printing money because that insults my intelligence. Using a lot of money to save something beyond rescue — the inefficient and corrupt banking and investment system — instead of investing in real stimulus was a bad decision, long term, mid term, and maybe even short term.”

Instead Kasparov says to “focus on the roots of the crisis — lack of technological innovation.” He said despite all the economic stimulus, unemployment in the U.S. still remains high, and that only restoring the technological lead of the country would help solve its woes.
