Perfectly Reasonable Problems

Feynman.jpg

I recently came across a note that strikes me as the clearest and most valuable advice a scholar might receive. The following letter, dated February 3, 1966, is part of an exchange between physicist Richard Feynman and his former student named Koichi Mano. Feynman asked Koichi what he was working on, to which Koichi responded, “studying 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) 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 depends 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.
Sincerely,
Richard P. Feynman.


Thank you to the Farnam Street blog for tipping me off to the existence of the letter. It appears in the collected letters of physicist Richard Feynman, published by his daughter in 2005 as Perfectly Reasonable Deviations from the Beaten Track.

Gary Larson on the Creative Process

Constraints, even arbitrary ones, are central to the creative process. Constraints force us to consider new alternatives, discard subconscious assumptions, and think outside the box. I've written about this before, but I'll be the first to admit that I lack the gravitas that others might bring to the issue. Gary Larson, for instance, has published 23 books, drawn a cover for the New Yorker, and even has a species of lice named after him. And here's what he says about his art:

Because The Far Side is a vertical, single-panel cartoon, I've rarely had the luxury of being able to draw long things (like whales, snakes, ships, etc.) in an accommodating shape. In general, the perspective has to be from front to rear, as opposed to side to side…
In cartoon strips, you frequently see the latter approach - because the strip lends itself well to horizontal images. In The Far Side... ships come at you head on, classrooms are viewed from either the front or the back, and riding in the car is often seen from the perspective of the backseat looking forward or from the windshield looking inward. I just can't draw a '59 Cadillac in profile. 
I'm saying this because I drew The Far Side for years without truly being cognizant of why I approached it this way. I was just trying to figure out ways to cram things into a little rectangle. It was a friend of mine (also a cartoonist) who pointed out that I had inadvertently developed one or two drawing skills in the process. 
The limitation of space I fought in the beginning ended up being the best drawing instructor I ever had.

From Larson's 1989 The PreHistory of the Far Side. Published without any accompanying cartoons per the artist's wishes.

Amazon and the "Profitless" Fallacy

This morning I came across a post by fellow San Franciscan Eugene Wei on Amazon's "profitless" business model. Guy Kawasaki sent it out to his 5.2M followers on G+, so I probably wasn't the only one. 

But that's beside the point. Anyone interested in strategy, the future of retail, or who just wants to know why items that are $15 in the real world are $10 on Amazon should read this article. Here's why: Amazon matters, and Amazon's business model matters. It's a behemoth that has got sticky fingers in basically every corner of the modern economy and the economic clout to drive a lot of other companies OUT of those corners. It has also remained, despite it's massive scale and technological prowess, stubbornly profitless. In fact, Amazon was once famously called "a charity run on behalf of consumers." But it isn't that. Amazon is a retail killing machine, and it's boss Jeff Bezos is an apex predator:

"To me, a profitless business model is one in which it costs you $2 to make a glass of lemonade but you have to sell it for $1 a glass at your lemonade stand. But if you sell a glass of lemonade for $2 and it only costs you $1 to make it, and you decide business is so great you're going to build a lemonade stand on every street corner in the world so you can eventually afford to move humanity into outer space or buy a newspaper in your spare time, and that requires you to invest all your profits in buying up some lemon fields and timber to set up lemonade franchises on every street corner, that sounds like a many things to me, but it doesn't sound like a charitable organization."
