Chapter 1Far Rockaway

Foreword

On 11 February 1986, a man who was dying of cancer took a piece of O-ring rubber, squeezed it in a C-clamp, dropped it into a glass of ice water, and ended an official story in about ten seconds on live television.

That is the most famous thing Richard Feynman ever did, and it is the reason for this book, and it is not quite what everybody thinks it is.

The argument here is that Feynman's charm was not decoration laid over the science. It was a working instrument, and this book is the accounting of what it bought and what it cost.

What it bought was the removal of deference from a room. A man who is manifestly not impressed by rank, who is funny, who asks the question a graduate student would be embarrassed to ask, strips the euphemism out of an institution faster than any amount of formal authority can. That is why the ice-water demonstration worked. It was not a discovery. It was a translation of something engineers already knew into a form a committee could not evade.

What it cost was scrutiny, and it cost it in the one direction he never looked.

He gave the most quoted sentence in the philosophy of science: the first principle is that you must not fool yourself, and you are the easiest person to fool. He said it at a Caltech commencement in 1974. He was by then several years into recording his own legend with a friend and a tape machine.

The book that came out of those tapes was published in 1985 and has never been out of print. It contains a chapter in which he is coached to treat a woman in a bar with calculated contempt, tries it, and reports that it worked. It contains stories that grew in the telling, stories that cannot be checked, and one piece of physics — the wobbling plate in the Cornell cafeteria — that he got slightly wrong every time he told it.

The instrument that made him unfoolable in a seminar left him one system he never tested, and it was himself.

Three chapters of this book are Los Alamos, and they come early.

He arrived at twenty-four, argued Hans Bethe to a standstill in his first weeks, was made a group leader for it, and learned to run a floor of IBM punch-card machines in parallel. He cracked safes. He baited the censors with coded letters. He kept walking through a hole in the fence.

That is a very funny set of stories and it is where he learned something more consequential: that the most serious room in the world can be survived by being funny in it.

And it is where he said the most honest thing of his life, thirty years later, buried inside a comic lecture. The original reason for building the bomb was Germany, and Germany surrendered in May 1945, and nobody stopped to think again — himself included.

Nobody has ever examined that sentence properly. Chapter 7 does, and leaves the question open rather than resolving it in his favor or against him.

Arline Greenbaum is in this book at length, and Chapter 4 is the only chapter in which he is not performing.

He had loved her since he was thirteen. She was diagnosed with tuberculosis and given a prognosis in years. He married her on 29 June 1942 on Staten Island, over his parents' objection, with two strangers as witnesses, and was forbidden to kiss her on the mouth. She spent his Los Alamos years in a sanatorium in Albuquerque, a hundred miles down from the mesa, reached by borrowed cars and hitched rides, and she died on 16 June 1945, a month before Trinity.

He did not cry that week. A dress in a shop window took him apart some time later. Sixteen months after her death he wrote her a letter and never mailed it, because he did not know her new address.

Chapter 16 is the one that will annoy his admirers and it has to be here.

Murray Gell-Mann was thirty years down the same corridor. George Sudarshan and Robert Marshak had the Fermi interaction result before the 1958 paper and did not get the citation. James Bjorken's scaling sits underneath the parton model of 1969.

None of that is theft, and this book does not allege it. It is what happens when one of the people in an argument is a much better storyteller than the others, and the story is what survives. Credit flows toward charm, and it flowed toward Feynman for forty years, and some of it belonged elsewhere.

Chapter 13 lays out his conduct toward women in his own words and attaches no verdict.

The affairs, the drawings, the topless bar where he worked on paper placemats and later testified for the house. And the objection raised while he was alive to hear it: protests in 1968 and again in 1972 against the lady-driver material in his lectures, a talk in San Francisco where he was called a sexist pig to his face, and his own written concession afterwards that women do face prejudice in physics.

No private woman is named in that chapter. None of them chose this.

And the book closes on Challenger because it is the instrument's vindication and its correction at the same time.

He was right. The seals failed in the cold and the management had been told. He was also not the man who found it. Roger Boisjoly and Arnie Thompson argued against launching below fifty-three degrees on the evening of 27 January 1986 and were overruled after their own management caucused, and Allan McDonald refused to sign the launch recommendation. Feynman got there via General Donald Kutyna, a story about a carburetor, and a tip that Kutyna said came from Sally Ride, who could not be seen to give it.

What Feynman supplied was ten seconds that a hearing room could not argue with.

Appendix F to the Rogers Commission report is his own separate investigation, conducted by walking down into the NASA engineering ranks and asking. It ends with the sentence that gives this book its title, and it is at the back of the report because he threatened to take his name off the whole thing unless it was printed.

Reality must take precedence over public relations, for Nature cannot be fooled.

He believed that completely, and applied it to everything, and there was one exception, and this book is about both halves of that.

Chapter 1 · Far Rockaway

In 1981 the BBC broadcast a film in which a physicist sat in a chair and talked. It ran on Horizon, the producer was Christopher Sykes, and it was called The Pleasure of Finding Things Out. It is, in effect, unedited — a man and a camera and very little else. He talks about the bomb. He talks about honesty. He talks about his father.

The story he told about his father, and went on telling, is about an encyclopedia and a bird. His father would sit him on his knee and read to him out of the encyclopedia, and the reading was never quite the point of the reading; the point was to get from the words on the page to the thing the words were standing in for. Then came the lesson, in the shape Feynman gave it for the rest of his life. You can learn the name of that bird in every language there is, his father told him — this is the son's version of it, retold across decades — and when you have finished you will know nothing whatever about the bird. You will know something about human beings, about what people in different places have agreed to call it. If you want to know about the bird, you have to watch the bird.

The lesson was working against the object in the father's hands. An encyclopedia is a machine for names. It is arranged by the accident of spelling rather than by any property of the world, it answers the question "what is this called" with great efficiency, and its entries close. Every one of them is designed to leave a reader satisfied. A man who reads an encyclopedia to a child in the ordinary way is transmitting exactly the wrong lesson at industrial speed: that the world comes pre-sorted, that each thing has an entry, and that having the entry is having the thing. Melville Feynman used the book against its own grain. He read the entry and then would not stop at it, and the destination of the reading was never a word.

It is an unusual thing to say to a child, because a name does not feel like an agreement. A name feels like knowledge. It arrives with the authority of the adult who supplies it, it fits the object exactly, and it has the particular property of ending the question that produced it. A child who asks what that is and receives an answer stops asking. That is what an answer is for. What Melville Feynman was drawing, on his knee, in Far Rockaway, was a line between the kind of fact that is settled by agreement among people and the kind that is settled by the world whether anybody agrees or not. His son spent the rest of his life enforcing that line — in seminars, in lecture halls, and eventually across a table from the administrators of a federal agency.

Richard Phillips Feynman was born on May 11, 1918, in Far Rockaway, out where New York City runs down the Rockaway peninsula and stops at the Atlantic. It is a corner of Queens that faces the ocean rather than the city. The family was Jewish. His mother was Lucille. His father, Melville, sold uniforms.

That last fact is worth holding still for a moment, because it is the kind of detail that a biography usually spends and moves past. A uniform salesman does not sell cloth. He sells the visible sign of office — the jacket, the braid, the cut that tells a room, before anybody in it has spoken a word, who is to be deferred to and in what order. Somebody has to stock those garments, price them, carry samples, and persuade a purchasing officer that this year's version is worth the difference. The man doing that work sees the equipment of authority from the wrong side, as inventory. What Melville Feynman actually sold, to whom, and in what territory, the record available for this book does not establish; the trade is attested, the details of it are not.

Nor does the record hand over the sentence in which he drew the obvious connection for his son. He is not on the page anywhere in this book's material saying that a uniform is a costume, or that the difference between the man in the braid and the man beside him is stitching. The connection between the trade and the lesson is an inference, and it belongs to this book rather than to its subject. But it is not a strained one. The suspicion of names that the son carried out of that house was of a specific kind. He was not skeptical of the world; he was extravagantly credulous about the world, willing to believe anything it demonstrated. He was skeptical of the labels people put on it and of the people who put them there. That is a distinction a child could plausibly learn from a father who spent his working days handling the labels.

Melville had wanted to be a scientist. He did not become one, and the reasons are not recorded here — a want is a hard thing to document at this distance, and the source for it is the family, testifying long afterward. What he did instead, according to that same family, was build one. The encyclopedia on the knee was not incidental parenting. It was a program, run on a small child, by a man who had a clear idea of the output he wanted. Read this way, the bird lesson stops being a charming origin anecdote and becomes something slightly stranger: a father transmitting to his son the discipline he had not been able to practice himself, and doing it early enough that the son never remembered acquiring it. Feynman did not present the lesson as something he had learned. He presented it as something he had always known.

There is a version of that sentence in which the father is a monster and the son is a project, and the record does not support it. Nothing in the available material shows the boy resisting, and nothing shows him resenting it afterward. He talked about his father with unmistakable warmth for the rest of his life, and when a camera was put in front of him to record what he thought about honesty, his father was among the things he chose to talk about. But the absence of resentment in a record composed almost entirely of the subject's own affectionate reminiscence is not evidence that there was none to record. It is a hole in the shape of the only witness.

The other thing Far Rockaway gave him was radios.

At some point in his boyhood the neighborhood's broken sets began arriving, and the boy repaired them. The formulation that survived — that he fixed radios by thinking — is the one the story is always told under, and it is doing more work than it looks like. The alternative to thinking, in radio repair, is poking. Poking is a perfectly rational strategy when you do not understand the machine: pull the tubes and reseat them, swap in a spare, wiggle the connections, tap the cabinet, and keep going until the noise stops. It works often enough to be worth doing. It is also indistinguishable, from the outside, from competence, which is part of why the neighborhood found the alternative so remarkable.

A receiver of that era is a chain. Power comes in at one end and sound comes out at the other, and in between there is a section that pulls one station out of the air and rejects the rest, a section that makes the resulting signal large enough to be useful, and a speaker that turns it into pressure in a room. Every stage in the chain can fail, and the ways it fails are not interchangeable. A dead set has a different disease from a set that hums, and a set that hums has a different disease from a set that plays but distorts, and a set that behaves for a while and then misbehaves has a different disease again. The symptom is not a nuisance to be silenced. The symptom is information about where in the chain the fault is sitting.

That is what fixing by thinking means, stripped of charm: listen to what the machine is doing wrong, reason from the failure back to the stage that could produce it, and open the cabinet where the reasoning says the fault is rather than everywhere at once. It is not a trick and it is not intuition. It is the same operation as the bird. The poker treats the radio as an object with a name — a broken radio — and attacks the name. The thinker treats it as a mechanism with parts that stand in known relations to each other, and asks which relation has failed. One approach ends when the noise stops. The other ends when you can say what happened.

It is worth being careful about what this does and does not establish. It does not establish that a boy in Far Rockaway had a gift nobody else had; plenty of children took radios apart in those years and a good number of them put them back together. What it establishes is a habit forming very early: the refusal to accept a description in place of a mechanism, applied first to a household appliance and then, with no apparent change of method, to everything else. He was still doing it at the end. Near the close of his life he would take an official explanation of a catastrophe, decline to accept it as an explanation, and go looking for the stage in the chain where the fault was actually sitting.

There is a second thing in the radio story, and it is the one this book will keep tripping over. "He fixes radios by thinking" is not a description of a method. It is a label — a short, memorable, slightly magical phrase that a neighborhood attached to a procedure it could not watch, because the procedure consisted almost entirely of a boy standing still. Nobody outside the house could see the reasoning. What they could see was a broken set going in and a working set coming out, with less rummaging than they expected, and so they named it. It is the earliest reputation Feynman had, and it was made in the ordinary way: by other people, in a hurry, out of the part of the performance that was visible. He did not object to it. He kept it, and it survived him. The boy who had been taught that a name tells you about the people who supplied it had acquired one of his own, and it was flattering, and it stuck.

Here the chapter has to stop and say where all of this comes from, because the answer matters more in this book than it would in most.

Almost the entire Far Rockaway record is Feynman's own retelling, with his sister's testimony beside it, and both were given decades after the events they describe. Corroboration is thin. There is no schoolteacher's letter about the boy and the radios in the material behind this chapter, no neighbor's account of the sets going in and out of the house, no page of Melville's in which he sets down what he was doing and why. There is a famous man in later life, telling stories about a childhood, to people who had every reason to enjoy them. The stories are not thereby false. But a biography that opens by asserting them flat, in the confident past tense, is doing exactly the thing the stories are about — accepting a name for a thing in place of the thing.

The tellings are also not all of one date, which is the only real leverage available. There is the 1981 film, made when he was already a public figure in Britain and knew what a camera was for. There are oral-history interviews recorded by the historian Charles Weiner for the American Institute of Physics across the mid-1960s to the early 1970s, in which Feynman told his life to a professional questioner years before any of it had been assembled into a book; the session dates and the running time of that collection are not established in the material behind this chapter, and nothing in this chapter should be read as a report of what those tapes say. And there are the two books of anecdotes, put together from tape by a drumming partner, on which the public reputation mostly rests. He would become, by a wide margin, the most beloved physicist of the twentieth century in the English-speaking world, and the affection was built far less on the physics — which almost nobody outside the field is equipped to evaluate — than on the storytelling. The order in which those sources were made is the closest thing this book has to an instrument for watching a story harden.

There is one number that always attaches itself to the boyhood, and this is the place to deal with it. The figure usually printed for his school IQ is 125 — respectable, unremarkable, and irresistible to anyone who wants to make the point that the tests do not measure what they claim to measure. It is repeated nearly everywhere and checked nearly nowhere. Its provenance does not survive contact with the sources available here: no test date, no administering school, no document. The honest position is that this book cannot source it, and there is a certain justice in that. A life spent insisting that a label is not the thing it names is a poor place to install, as a load-bearing fact about a schoolboy, a number that nobody has gone back to look at.

What the record does support is narrower and more useful. It supports a household in which explanation was the currency, run by a father who had wanted a career he did not get and who spent his son's childhood installing the equipment for one. It supports a boy who took the machinery of the adult world apart rather than accepting the account of it he was offered. And it supports the beginning of a disposition that is easy to admire in the abstract and was frequently difficult in the room: a settled inability to be impressed by a title.

The disposition is traceable forward, and the traces are not subtle. He could not use a piece of physics until he had rebuilt it from the beginning for himself, which is an expensive way to work and left him, on more than one occasion, holding a result nobody else could follow. On a sabbatical in Brazil he stood in front of a room of science teachers and ministry officials and told them that their students had memorized everything and understood nothing — the bird lesson delivered back to a country's education system by a visitor who had been given it on a knee. And he applied it, with some consistency, to the honors of his own profession. He resigned from the National Academy of Sciences; the fact of the resignation is solid, while the year and the reason usually attached to it — that he had no use for an organization whose principal business was deciding whom to let in — are reported rather than documented, and this book does not treat them as settled. When the largest name available in physics was offered to him, he gave serious thought to not going to collect it. None of that is modesty. Modesty is a posture adopted toward an honor you accept as real. This was closer to a category error, honestly held: an inability to see why the label should be interesting when the work it was attached to was sitting right there.

That inability did two things at once, and the argument of this book is that they are not separable. It stripped deference and euphemism out of a room. A man who does not care what your position is will ask you the question that your position was constructed to make unaskable, and he will ask it in front of other people, pleasantly, without appearing to notice that he has done anything. Applied to physics, that faculty was worth more than most people's talent. Applied to institutions, it was worth more still. In February 1986, on live television, a dying man would drop a piece of O-ring rubber into a glass of ice water in front of a presidential commission and demolish an official story with an object a child could have handled. The lesson from the encyclopedia is legible in that gesture. Do not tell me the name of the failure mode. Show me the rubber. Show me the cold.

But the same disposition has a blind side, and it is the one this book keeps returning to. A man who cannot be fooled by other people's labels is not thereby protected from his own. The lesson Melville taught was directed outward, at claims made by other people about the world. It contained no instruction for the case where the claim is about you, and where the person supplying the pleasing description is you, and where the audience is delighted and has no wish to check. He would eventually stand in front of a graduating class and tell them, with total sincerity, that the easiest person in the world to fool is yourself. He was at that point several years into the project of taping his own legend, with a friend and a microphone, and assembling out of it a version of himself that could not readily be checked by anybody.

None of that is visible yet at the ocean end of Queens. What is visible is a boy on a knee, an encyclopedia open on a lap, a bird that has a name in every language and remains unknown in all of them, and a father in the uniform trade who had wanted to be a scientist and settled for manufacturing one. Melville got what he was after. The son who came out of that household could take almost any claim apart, in front of almost anybody, and went on doing it to the end of his life.

He would just never quite get around to running the procedure on himself.
