A little puzzle
Dr. N.K. sent me a little puzzle.
Construct the Fill of a set of points by drawing all the lines (extending to infinity) using every pair of points in the set. Thus the Fill of three non-collinear points is the triangle with the 3 points as vertices and the edges extended to infinity. The Fill * Fill of three non-collinear points is the whole plane.
The question is: what is the Fill * Fill of four non-coplanar points? Is it all of space (Euclidean 3D space)?
Answer beneath the fold.

Who am I?
1-10% of me (depending on how you count it) was blown away by this in the New York Times: (emphasis added). No doubt, some large part of me already knew this.
"As they look beyond the genome, cancer researchers are also awakening to the fact that some 90 percent of the protein-encoding cells in our body are microbes. We evolved with them in a symbiotic relationship, which raises the question of just who is occupying whom."
“We are massively outnumbered,” said Jeremy K. Nicholson, chairman of biological chemistry and head of the department of surgery and cancer at Imperial College London. Altogether, he said, 99 percent of the functional genes in the body are microbial.
Murdochs in the dock
Further revelations.
Rupert Murdoch, James Murdoch and their former editor Andy Coulson all face embarrassing new allegations of dishonesty and cover-up after the publication of an explosive letter written by the News of the World's disgraced royal correspondent, Clive Goodman.
In the letter, which was written four years ago but published only on Tuesday, Goodman claims that phone hacking was "widely discussed" at editorial meetings at the paper until Coulson himself banned further references to it; that Coulson offered to let him keep his job if he agreed not to implicate the paper in hacking when he came to court; and that his own hacking was carried out with "the full knowledge and support" of other senior journalists, whom he named.
College/Non-College Social Norms
Yglesias points to some. In light of Dalrymple's essays on England, pointing out similar issues, this is interesting. In particular:
Between 2006 and 2008, among moderately educated women, 44 percent of all births occurred outside marriage, not far off the rate (54 percent) among high-school dropouts; among college-educated women, that proportion was just 6 percent.
The same pattern—families of middle-class nonprofessionals now resembling those of high-school dropouts more than those of college graduates—emerges with norm after norm: the percentage of 14-year-old girls living with both their mother and father; the percentage of adolescents wanting to attend college “very much”; the percentage of adolescents who say they’d be embarrassed if they got (or got someone) pregnant; the percentage of never-married young adults using birth control all the time.

Dalrymple
Theodore Dalrymple I know only through his essays (not his books). For instance.
First and foremost he is a good and interesting writer. He also comes off as a honest and compassionate person. Second, he challenges liberal views, and it would be good for liberals to address what he has to say. Third, while he writes anecdotally, as a prison doctor and psychiatrist, his anecdotes are backed by many cases.
I think three good reasons are sufficient for me to provide as to why I follow his writings. In the idea that culture matters, I agree broadly with him.

Theodore Dalrymple on the London riots
In The Australian.
British youth leads the Western world in almost all aspects of social pathology, from teenage pregnancy to drug taking, from drunkenness to violent criminality. There is no form of bad behaviour that our version of the welfare state has not sought out and subsidised.
British children are much likelier to have a television in their bedroom than a father living at home. One-third of them never eat a meal at a table with another member of their household -- family is not the word for the social arrangements of the people in the areas from which the rioters mainly come. They are therefore radically unsocialised and deeply egotistical, viewing relations with other human beings in the same way as Lenin: Who whom, who does what to whom. By the time they grow up, they are destined not only for unemployment but unemployability.

Much less made in China
Such is the claim (over at Matthew Yglesias):
A very interesting analysis by Galina Hale and Bart Hobijn of the San Francisco Fed concludes that very little of American personal consumption spending actually ends up in China. When Americans go buy stuff, they’re overwhelmingly buying things that are made in America:
In part, this reflects the fact that 67 percent of spending is on services rather than goods, and services are 96 percent made in the USA. But even durable goods, which only account for about 10 percent of total spending, are mostly made in America — 66.6 percent to 12 percent for China with the rest coming from the rest of the world. In fact the only category of spending in which Made in the USA doesn’t account for the majority is clothing and shoes. What’s more, even a lot of the spending on imported goods actually reflects the cost of shipping them around the United States:
Table 1 shows that, of the 11.5% of U.S. consumer spending that goes for goods and services produced abroad, 7.3% reflects the cost of imports. The remaining 4.2% goes for U.S. transportation, wholesale, and retail activities. Thus, 36% of the price U.S. consumers pay for imported goods actually goes to U.S. companies and workers.
This U.S. fraction is much higher for imports from China. Whereas goods labeled “Made in China” make up 2.7% of U.S. consumer spending, only 1.2% actually reflects the cost of the imported goods. Thus, on average, of every dollar spent on an item labeled “Made in China,” 55 cents go for services produced in the United States. In other words, the U.S. content of “Made in China” is about 55%. The fact that the U.S. content of Chinese goods is much higher than for imports as a whole is mainly due to higher retail and wholesale margins on consumer electronics and clothing than on most other goods and services.

How not to negotiate
Kurt Andersen, in the New York Times:
I had breakfast this week with one of Hollywood’s most ferocious, self-confident and successful doers of deals. He was still steamed about what an unforgivably lousy negotiator his president had been on the debt ceiling agreement.

What for?

And unless we find a way to go interstellar - or at least, not depend on a planetary surface for our survival - this chain of life will eventually end.
PS: A Hindu story to help reconcile you to all of the above.

A Lesson
Posted by Atri on BRF
क्षमा, दया , ताप , त्याग , मनोबल सबका लिया सहारा
पर नर व्याघ सुयोधन तुमसे कहो कहाँ कब हारा?
क्षमाशील हो रिपु समक्ष तुम हुए विनीत जितना ही
दुष्ट कौरवों ने तुमको कायर समझा उतना ही
अत्याचार सहन करने का कुफल यही होता है
पौरुष का आतंक मनुज कोमल होकर खोता है
क्षमा शोभती उस भुजंग को जिसके पास गरल है
उसका क्या जो दंतहीन विषरहित विनीत सरल है
तीन दिवस तक पंथ मांगते रघुपति सिन्धु किनारे
बैठे पढते रहे छंद अनुनय के प्यारे प्यारे
उत्तर में जब एक नाद भी उठा नहीं सागर से
उठी अधीर धधक पौरुष की आग राम के शर से
सिन्धु देह धर त्राहि-त्राहि करता आ गिरा शरण में
चरण पूज दासता ग्र्र्हन की बंधा मूढ़ बंधन में
सच पूछो तो शर में ही बस्ती है दीप्ति विनय की
संधिवचन संपूज्य उसीका जिसमे शक्ति विजय की
सहनशीलता, क्षमा, दया को तभी पूजता जग है
बल का दर्प चमकता उसके पीछे जब जगमग है
-रामधरी सिंह दिनकर
Mercy, resolve, tact, tolerance you've tried everything and some
But o my king of men when did Suyodhan succumb?
The more forgiving you were In your humane compassion
The more these rogue Kauravas pegged you as cowardly ashen
This is the consequence Of tolerating atrocities
The awe of machismo is lost When one's gentle n kindly
Forgiveness is becoming of The serpent that's got venom
None cares for the toothless, Poisonless, kind, gentle one
For three days Lord Raam kept Asking the ocean for a passage
Sitting there he petitioned Using the sweetest words to engage
When in response there was Not a whisper from the sea
A raging fire of endeavor Rose from Raam's body
The ocean took human-form 'N supplicated to Raam
Touched his feet, was subservient A slave he had become
Truth be told, it's in the quiver That lies the gleam of modesty
Only his peace-talk is reputable Who is capable of victory
Tolerance, forgiveness and clemency Are respected by the world
Only when the glow of strength From behind it is unfurled
