Richard Feynman’s Letter on What Problems to Solve

"The worthwhile problems are the ones you can really solve or help solve, the ones you can really contribute something to."

“No problem is too small or too trivial if we can really do something about it.”

In a letter dated February 3rd, 1966, included in the wonderful anthology Perfectly Reasonable Deviations From the Beaten Track: The Letters of Richard Feynman, Richard Feynman (1918-1988) timelessly describes “worthwhile problems.” We tend to think of these problems as the big ones, though they need not be.

The letter, is part of a chain of communication that started with a former student, Koichi Manom, who had written to extend his congratulations. Richard Feynman asked him what he was doing. Koichi responded: “studying the Coherence theory with some applications to the propagation of electromagnetic waves through turbulent atmosphere … a humble and down-to-earth type of problem.”

Dear Koichi,

I was very happy to hear from you, and that you have such a position in the Research Laboratories. Unfortunately your letter made me unhappy for you seem to be truly sad. It seems that the influence of your teacher has been to give you a false idea of what are worthwhile problems. The worthwhile problems are the ones you can really solve or help solve, the ones you can really contribute something to. A problem is grand in science if it lies before us unsolved and we see some way for us to make some headway into it. I would advise you to take even simpler, or as you say, humbler, problems until you find some you can really solve easily, no matter how trivial. You will get the pleasure of success, and of helping your fellow man, even if it is only to answer a question in the mind of a colleague less able than you. You must not take away from yourself these pleasures because you have some erroneous idea of what is worthwhile.

You met me at the peak of my career when I seemed to you to be concerned with problems close to the gods. But at the same time I had another Ph.D. Student (Albert Hibbs) whose thesis was on how it is that the winds build up waves blowing over water in the sea. I accepted him as a student because he came to me with the problem he wanted to solve. With you I made a mistake, I gave you the problem instead of letting you find your own; and left you with a wrong idea of what is interesting or pleasant or important to work on (namely those problems you see you may do something about). I am sorry, excuse me. I hope by this letter to correct it a little.

I have worked on innumerable problems that you would call humble, but which I enjoyed and felt very good about because I sometimes could partially succeed. For example, experiments on the coefficient of friction on highly polished surfaces, to try to learn something about how friction worked (failure). Or, how elastic properties of crystals depend on the forces between the atoms in them, or how to make electroplated metal stick to plastic objects (like radio knobs). Or, how neutrons diffuse out of Uranium. Or, the reflection of electromagnetic waves from films coating glass. The development of shock waves in explosions. The design of a neutron counter. Why some elements capture electrons from the L-orbits, but not the K-orbits. General theory of how to fold paper to make a certain type of child’s toy (called flexagons). The energy levels in the light nuclei. The theory of turbulence (I have spent several years on it without success). Plus all the “grander” problems of quantum theory.

No problem is too small or too trivial if we can really do something about it.

You say you are a nameless man. You are not to your wife and to your child. You will not long remain so to your immediate colleagues if you can answer their simple questions when they come into your office. You are not nameless to me. Do not remain nameless to yourself – it is too sad a way to be. Know your place in the world and evaluate yourself fairly, not in terms of your naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher’s ideals are.

Best of luck and happiness.

Charles Bukowski: An Argument Against Censorship

Bukowski’s robust defense hangs proudly in the Open Dicht Bus, a mobile bookshop.
Bukowski’s defense hangs in the Open Dicht Bus, a mobile bookshop.

In 1985, staff at a public library, acting on a complaint, decided to to remove Charles Bukowski’s 1983 collection of short stories, Tales of Ordinary Madness, from their shelves. They declared the stories “sadistic, occasionally fascist and discriminatory against certain groups (including homosexuals).”

A local journalist, Hans van den Broek, wrote to Charles Bukowski, informing him of the situation and asking for his opinion on such censorship. His reply, found in the amazing collection Letters of Note, is worth reading.

Dear Hans van den Broek:

Thank you for your letter telling me of the removal of one of my books from the Nijmegen library. And that it is accused of discrimination against black people, homosexuals and women. And that it is sadism because of the sadism.

The thing that I fear discriminating against is humor and truth.

If I write badly about blacks, homosexuals and women it is because of these who I met were that. There are many “bads”–bad dogs, bad censorship; there are even “bad” white males. Only when you write about “bad” white males they don’t complain about it. And need I say that there are “good” blacks, “good” homosexuals and “good” women?

In my work, as a writer, I only photograph, in words, what I see. If I write of “sadism” it is because it exists, I didn’t invent it, and if some terrible act occurs in my work it is because such things happen in our lives. I am not on the side of evil, if such a thing as evil abounds. In my writing I do not always agree with what occurs, nor do I linger in the mud for the sheer sake of it. Also, it is curious that the people who rail against my work seem to overlook the sections of it which entail joy and love and hope, and there are such sections. My days, my years, my life has seen up and downs, lights and darknesses. If I wrote only and continually of the “light” and never mentioned the other, then as an artist I would be a liar.

Censorship is the tool of those who have the need to hide actualities from themselves and from others. Their fear is only their inability to face what is real, and I can’t vent any anger against them. I only feel this appalling sadness. Somewhere, in their upbringing, they were shielded against the total facts of our existence. They were only taught to look one way when many ways exist.

I am not dismayed that one of my books has been hunted down and dislodged from the shelves of a local library. In a sense, I am honored that I have written something that has awakened these from their non-ponderous depths. But I am hurt, yes, when somebody else’s book is censored, for that book, usually is a great book and there are few of those, and throughout the ages that type of book has often generated into a classic, and what was once thought shocking and immoral is now required reading at many of our universities.

I am not saying that my book is one of those, but I am saying that in our time, at this moment when any moment may be the last for many of us, it’s damned galling and impossibly sad that we still have among us the small, bitter people, the witch-hunters and the declaimers against reality. Yet, these too belong with us, they are part of the whole, and if I haven’t written about them, I should, maybe have here, and that’s enough.

may we all get better together,

The Skills of Leonardo Da Vinci

Leonardo Da Vinci

Italian polymath Leonardo da Vinci sought a job at the court of Ludovico Sforza, then the ruler of Milan. Leonardo’s application letter, found in the amazing Letters of Note, included a ten-point list of his abilities. Keep in mind that Sforza was looking for military engineers.

My Most Illustrious Lord,

Having now sufficiently seen and considered the achievements of all those who count themselves masters and artificers of instruments of war, and having noted that the invention and performance of the said instruments is in no way different from that in common usage, I shall endeavor, while intending no discredit to anyone else, to make myself understood to Your Excellency for the purpose of unfolding to you my secrets, and thereafter offering them at your complete disposal, and when the time is right bringing into effective operation all those things which are in part briefly listed below:

1. I have plans for very light, strong and easily portable bridges with which to pursue and, on some occasions, flee the enemy, and others, sturdy and indestructible either by fire or in battle, easy and convenient to lift and place in position. Also means of burning and destroying those of the enemy.

2. I know how, in the course of the siege of a terrain, to remove water from the moats and how to make an infinite number of bridges, mantlets and scaling ladders and other instruments necessary to such an enterprise.

3. Also, if one cannot, when besieging a terrain, proceed by bombardment either because of the height of the glacis or the strength of its situation and location, I have methods for destroying every fortress or other stranglehold unless it has been founded upon a rock or so forth.

4. I have also types of cannon, most convenient and easily portable, with which to hurl small stones almost like a hail-storm; and the smoke from the cannon will instill a great fear in the enemy on account of the grave damage and confusion.

5. Also, I have means of arriving at a designated spot through mines and secret winding passages constructed completely without noise, even if it should be necessary to pass underneath moats or any river.

6. Also, I will make covered vehicles, safe and unassailable, which will penetrate the enemy and their artillery, and there is no host of armed men so great that they would not break through it. And behind these the infantry will be able to follow, quite uninjured and unimpeded.

7. Also, should the need arise, I will make cannon, mortar and light ordnance of very beautiful and functional design that are quite out of the ordinary.

8. Where the use of cannon is impracticable, I will assemble catapults, mangonels, trebuchets and other instruments of wonderful efficiency not in general use. In short, as the variety of circumstances dictate, I will make an infinite number of items for attack and defence.

9. And should a sea battle be occasioned, I have examples of many instruments which are highly suitable either in attack or defense, and craft which will resist the fire of all the heaviest cannon and powder and smoke.

10. In time of peace I believe I can give as complete satisfaction as any other in the field of architecture, and the construction of both public and private buildings, and in conducting water from one place to another.

Also I can execute sculpture in marble, bronze, and clay. Likewise in painting, I can do everything possible as well as any other, whosoever he may be.

Moreover, work could be undertaken on the bronze horse which will be to the immortal glory and eternal honour of the auspicious memory of His Lordship your father, and of the illustrious house of Sforza.

And if any of the above-mentioned things seem impossible or impracticable to anyone, I am most readily disposed to demonstrate them in your park or in whatsoever place shall please Your Excellency, to whom I commend myself with all possible humility.

Kurt Vonnegut’s Powerful 1973 Letter to the Man Burning his Books

Kurt Vonnegut

Shawn Usher beautifully sets the context in Letters of Note: An Eclectic Collection of Correspondence Deserving of a Wider Audience:

Since first being published in 1967— and despite being considered one of the great modern novels—Kurt Vonnegut’s time-hopping, semiauto-biographical, antiwar classic, Slaughterhouse-Five, has been and continues to be banned from classrooms and libraries the world over. This is due to what is often described by those who censor it as its “obscene” content. A different view was held by Bruce Severy, a twenty-six-year-old English teacher at Drake High School, North Dakota, in 1973, who decided to use the novel as a teaching aid in his classroom, much to the delight of his students. The head of the school board, Charles McCarthy, had other ideas, however: He demanded that all thirty-two copies be burned in the school’s furnace. Many of the students protested the decision; some even refused to hand their books back. Their admirable stance was ignored. On November 16, 1973, an angry and disappointed Vonnegut wrote to McCarthy to make his feelings known. His powerful letter failed to generate a reply.

Here’s the letter.

November 16, 1973
Dear Mr. McCarthy:

I am writing to you in your capacity as chairman of the Drake School Board. I am among those American writers whose books have been destroyed in the now famous furnace of your school.

Certain members of your community have suggested that my work is evil. This is extraordinarily insulting to me. The news from Drake indicates to me that books and writers are very unreal to you people. I am writing this letter to let you know how real I am.

I want you to know, too, that my publisher and I have done absolutely nothing to exploit the disgusting news from Drake. We are not clapping each other on the back, crowing about all the books we will sell because of the news. We have declined to go on television, have written no fiery letters to editorial pages, have granted no lengthy interviews. We are angered and sickened and saddened. And no copies of this letter have been sent to anybody else. You now hold the only copy in your hands. It is a strictly private letter from me to the people of Drake, who have done so much to damage my reputation in the eyes of their children and then in the eyes of the world. Do you have the courage and ordinary decency to show this letter to the people, or will it, too, be consigned to the fires of your furnace?

I gather from what I read in the papers and hear on television that you imagine me, and some other writers, too, as being sort of ratlike people who enjoy making money from poisoning the minds of young people. I am in fact a large, strong person, fifty-one years old, who did a lot of farm work as a boy, who is good with tools. I have raised six children, three my own and three adopted. They have all turned out well. Two of them are farmers. I am a combat infantry veteran from World War II, and hold a Purple Heart. I have earned whatever I own by hard work. I have never been arrested or sued for anything. I am so much trusted with young people and by young people that I have served on the faculties of the University of Iowa, Harvard, and the City College of New York. Every year I receive at least a dozen invitations to be commencement speaker at colleges and high schools. My books are probably more widely used in schools than those of any other living American fiction writer.

If you were to bother to read my books, to behave as educated persons would, you would learn that they are not sexy, and do not argue in favor of wildness of any kind. They beg that people be kinder and more responsible than they often are. It is true that some of the characters speak coarsely. That is because people speak coarsely in real life. Especially soldiers and hardworking men speak coarsely, and even our most sheltered children know that. And we all know, too, that those words really don’t damage children much. They didn’t damage us when we were young. It was evil deeds and lying that hurt us.

After I have said all this, I am sure you are still ready to respond, in effect, “Yes, yes— but it still remains our right and our responsibility to decide what books our children are going to be made to read in our community.” This is surely so. But it is also true that if you exercise that right and fulfill that responsibility in an ignorant, harsh, un-American manner, then people are entitled to call you bad citizens and fools. Even your own children are entitled to call you that.

I read in the newspaper that your community is mystified by the outcry from all over the country about what you have done. Well, you have discovered that Drake is a part of American civilization, and your fellow Americans can’t stand it that you have behaved in such an uncivilized way. Perhaps you will learn from this that books are sacred to free men for very good reasons, and that wars have been fought against nations which hate books and burn them. If you are an American, you must allow all ideas to circulate freely in your community, not merely your own.

If you and your board are now determined to show that you in fact have wisdom and maturity when you exercise your powers over the education of your young, then you should acknowledge that it was a rotten lesson you taught young people in a free society when you denounced and then burned books— books you hadn’t even read. You should also resolve to expose your children to all sorts of opinions and information, in order that they will be better equipped to make decisions and to survive.

Again: you have insulted me, and I am a good citizen, and I am very real.

Kurt Vonnegut

Eudora Welty to The New Yorker— The best job application ever


In March of 1933, Eudora Welty, then 23 and looking for writing work, sent this beautiful letter to the offices of The New Yorker. “It’s difficult,” writes Shaun Usher in his introduction to the letter in Letters of Note, “to imagine a more endearingly written introduction to one’s talents.”

March 15, 1933


I suppose you’d be more interested in even a sleight-o’-hand trick than you’d be in an application for a position with your magazine, but as usual you can’t have the thing you want most.

I am 23 years old, six weeks on the loose in N.Y. However, I was a New Yorker for a whole year in 1930– 31 while attending advertising classes in Columbia’s School of Business. Actually I am a southerner, from Mississippi, the nation’s most backward state. Ramifications include Walter H. Page, who, unluckily for me, is no longer connected with Doubleday-Page, which is no longer Doubleday-Page, even. I have a B.A. (’ 29) from the University of Wisconsin, where I majored in English without a care in the world. For the last eighteen months I was languishing in my own office in a radio station in Jackson, Miss., writing continuities, dramas, mule feed advertisements, santa claus talks, and life insurance playlets; now I have given that up.

As to what I might do for you— I have seen an untoward amount of picture galleries and 15¢ movies lately, and could review them with my old prosperous detachment, I think; in fact, I recently coined a general word for Matisse’s pictures after seeing his latest at the Marie Harriman: concubineapple. That shows you how my mind works—quick, and away from the point. I read simply voraciously, and can drum up an opinion afterwards.

Since I have bought an India print, and a large number of phonograph records from a Mr. Nussbaum who picks them up, and a Cezanne Bathers one inch long (that shows you I read e. e. cummings I hope), I am anxious to have an apartment, not to mention a small portable phonograph. How I would like to work for you! A little paragraph each morning— a little paragraph each night, if you can’t hire me from daylight to dark, although I would work like a slave. I can also draw like Mr. Thurber, in case he goes off the deep end. I have studied flower painting.

There is no telling where I may apply, if you turn me down; I realize this will not phase you, but consider my other alternative: the U of N.C. offers for $12.00 to let me dance in Vachel Lindsay’s Congo. I congo on. I rest my case, repeating that I am a hard worker.

The New Yorker, missing the obvious talent, ignored her plea before eventually correcting their mistake. Welty went on to win multiple awards including the Pulitzer Prize for Fiction in 1973 for her novel The Optimist’s Daughter.

Sol LeWitt on the Power of Doing

Stop is and just DO
Stop it and just DO

In 1960 two American artists met for the first time: Sol LeWitt and Eva Hesse. The meeting sparked a bond that resulted in “countless inspirational discussions and rich exchanged of ideas” until Hesse passed away in 1970.

In 1965 Hesse was facing a creative block, plagued with self-doubt. She told LeWitt who replied with this work of art found in Letters of Note. “An invaluable letter of advice, it has since inspired many other artists, and copies now grace the walls of art studios the world over.”

Dear Eva,
April 14

It will be almost a month since you wrote to me and you have possibly forgotten your state of mind (I doubt it though). You seem the same as always, and being you, hate every minute of it. Don’t! Learn to say “Fuck You” to the world once in a while. You have every right to. Just stop thinking, worrying, looking over your shoulder, wondering, doubting, fearing, hurting, hoping for some easy way out, struggling, grasping, confusing, itching, scratching, mumbling, bumbling, grumbling, humbling, stumbling, numbling, rambling, gambling, tumbling, scumbling, scrambling, hitching, hatching, bitching, moaning, groaning, honing, boning, horse-shitting, hair-splitting, nit-picking, piss-trickling, nose sticking, ass-gouging, eyeball-poking, finger-pointing, alleyway-sneaking, long waiting, small stepping, evil-eyeing, back-scratching, searching, perching, besmirching, grinding, grinding, grinding away at yourself. Stop it and just


From your description, and from what I know of your previous work and your ability; the work you are doing sounds very good “Drawing— clean— clear but crazy like machines, larger and bolder . . . real nonsense.” That sounds fine, wonderful—real nonsense. Do more. More nonsensical, more crazy, more machines, more breasts, penises, cunts, whatever— make them abound with nonsense. Try and tickle something inside you, your “weird humor.” You belong in the most secret part of you. Don’t worry about cool, make your own uncool. Make your own, your own world. If you fear, make it work for you— draw & paint your fear & anxiety. And stop worrying about big, deep things such as “to decide on a purpose and way of life, a consistant approach to even some impossible end or even an imagined end.” You must practice being stupid, dumb, unthinking, empty. Then you will be able to


I have much confidence in you and even though you are tormenting yourself, the work you do is very good. Try to do some BAD work— the worst you can think of and see what happens but mainly relax and let everything go to hell— you are not responsible for the world— you are only responsible for your work— so DO IT. And don’t think that your work has to conform to any preconceived form, idea or flavor. It can be anything you want it to be. But if life would be easier for you if you stopped working— then stop. Don’t punish yourself. However, I think that it is so deeply engrained in you that it would be easier to


It seems I do understand your attitude somewhat, anyway, because I go through a similar process every so often. I have an “Agonizing Reappraisal” of my work and change everything as much as possible— and hate everything I’ve done, and try to do something entirely different and better. Maybe that kind of process is necessary to me, pushing me on and on. The feeling that I can do better than that shit I just did. Maybe you need your agony to accomplish what you do. And maybe it goads you on to do better. But it is very painful I know. It would be better if you had the confidence just to do the stuff and not even think about it. Can’t you leave the “world” and “ART” alone and also quit fondling your ego. I know that you (or anyone) can only work so much and the rest of the time you are left with your thoughts. But when you work or before your work you have to empty your mind and concentrate on what you are doing. After you do something it is done and that’s that. After a while you can see some are better than others but also you can see what direction you are going. I’m sure you know all that. You also must know that you don’t have to justify your work—not even to yourself. Well, you know I admire your work greatly and can’t understand why you are so bothered by it. But you can see the next ones & I can’t. You also must believe in your ability. I think you do. So try the most outrageous things you can— shock yourself. You have at your power the ability to do anything.

I would like to see your work and will have to be content to wait until Aug or Sept. I have seen photos of some of Tom’s new things at Lucy’s. They are very impressive—especially the ones with the more rigorous form; the simpler ones. I guess he’ll send some more later on. Let me know how the shows are going and that kind of stuff.

My work has changed since you left and it is much better. I will be having a show May 4– 29 at the Daniels Gallery 17 E 64th St (where Emmerich was), I wish you could be there. Much love to you both.
