Book Quote of the Day


It is no tragedy to think of the most successful people in any field as superheroes. But it is a tragedy when a belief in the judgment of experts or the marketplace rather than a belief in ourselves causes us to give up, as John Kennedy Toole did when he committed suicide after publishers repeatedly rejected his manuscript for the posthumously best-selling Confederacy of Dunces...
What I’ve learned, above all, is to keep marching forward because the best news is that since chance does play a role, one important factor in success is under our control: the number of at bats, the number of chances taken, the number of opportunities seized. For even a coin weighted toward failure will sometimes land on success. Or as the IBM pioneer Thomas Watson said, “If you want to succeed, double your failure rate.”

A Mathematician tried moving a table

William Feller was a probability theorist at Princeton University. One day he and his wife wanted to move a large table from one room of their large house to another, but, try as they might, they couldn’t get it though the door. They pushed and pulled and tipped the table on its side and generally tried everything they could, but it just wouldn’t go.

Eventually, Feller went back to his desk and worked out a mathematical proof that the table would never be able to pass through the door.

While he was doing this, his wife got the table through the door
-Professor Stewart’s Hoard of Mathematical Treasures

More on Feller;
His lectures were loud and entertaining. He wrote very large on the blackboard, in a beautiful Italianate handwriting with lots of whirls. Sometimes only one huge formula appeared on the blackboard during the entire period; the rest was handwaving. His proof—insofar as one can speak of proofs—were often deficient. Nonethless, they were convincing, and the results became unforgettably clear after he had explained them. The main idea was never wrong.

He took umbrage when someone interrupted his lecturing by pointing out some glaring mistake. He became red in the face and raised his voice, often to full shouting range. It was reported that on occasion he had asked the objector to leave the classroom. The expression "proof by intimidation" was coined after Feller's lectures (by Mark Kac). During a Feller lecture, the hearer was made to feel privy to some wondrous secret, one that often vanished by magic as he walked out of the classroom at the end of the period. Like many great teachers, Feller was a bit of a con man.

I learned more from his rambling lectures than from those of anyone else at Princeton. I remember the first lecture of his I ever attended. It was also the first mathematics course I took at Princeton (a course in sophomore differential equations). The first impression he gave was one of exuberance, of great zest for living, as he rapidly wrote one formula after another on the blackboard while his white mane floated in the air. After the first lecture, I had learned two words which I had not previously heard: "lousy" and "nasty."

What do Blind Mathematicians Study

I was surprised to learn that the majority work in geometry, supposedly the most ‘visual’ discipline, and fascinated to learn that they generally believe the experience of sight puts people at a disadvantage because it locks us into a perception-led view of space.

Be a Statistician, Be a Cynic

I have a feeling that statisticians are cynics, because you realise how much of the stuff that you are told is true in the world is actually just that month’s accident that worked out, or that month’s disaster that happened.
Appreciating how much randomness there is in everyday experience helps a lot."-Efron on statisticians

What exactly is a burst?
ALB: A burst is a sudden escalation in our activity pattern, characterized by an excessive focus on a certain type of task at the exclusion of all other responsibilities. It is like the thunder of drums in a Beethoven masterpiece, punctuated by the pleasing sound of the violins that preceded and follow them

It may not be autism

Almost 50% of the children previously diagnosed with autism are found to be suffering from some degree of brain seizure activity that is undetectable to the eye...In the cases where these seizures are the cause of the symptoms, once the seizures have been detected and treated, the level and speed of recovery in the children has been remarkable.

“The meaning of life is that it ends”- Kafka

Just finished reading the book 'How Doctors Think' by Jerome Groopman.

Came across two moving stories from the NYT- I recommend the book to every one.

Floyd Norris talks about his cancer treatment.

I am undergoing radiation and drug treatment for cancer.

The drug is Erbitux, which at least is something I had heard about. (You may recall that was the drug involved in the Martha Stewart lying-to-the-S.E.C. case.) It has made my face look worse than anyone’s face ever looked when I was in high school.

I know that it is not news that radiation treatment can be miserable. I did not do all the homework I could have done, so perhaps I should have been better prepared.

But the pain involved is more than I have ever experienced. It is virtually impossible for me to eat. I am losing weight at an impressive rate, to the dismay of the radiation doctor. I have little energy, which is probably both because of the radiation directly and because of the lack of nutrition...

It is not fun, but it has been inspiring. In a way, I am happier about my life than at any time I can remember. Clint Eastwood once asked, “Do you feel lucky?” My answer is a shouted yes...

I am 62, and have had the honor of being a financial columnist here for more than 20 years. I have been happily married for 26 years, and last Friday saw our son graduate from high school. He will be attending an excellent college in the fall.

I hope to have a lot more years. But I’ve had a lot already, and they have been better than a lot of people have any reason to hope for. I am grateful.

A Scare, a Scar, a Silver Lining;
This is trite but also so, so true: A brush with mortality turns out to be the best way to appreciate how blue the sky is, how sensuous grass feels underfoot, how melodious kids’ voices are. Even teenagers’ voices. A friend and colleague, David E. Sanger, who conquered cancer a decade ago, says, “No matter how bad a day you’re having, you say to yourself: ‘I’ve had worse.’
