Hamming's talk
Richard W. Hamming completed his PhD in mathematics in 1942. He was hired by the
Manhattan Project in Los Alamos to take over the computing facilities
that the physicists had set up. Hamming felt "a stooge", was envious,
as he worked with people such as Bethe, Teller, Feynman. He wondered
what made these people what they were, what set apart "those who did
from those who might have done". As a result, he made the conscious
decision: "Yes, I want to do first-class work". Later in the talk, he
refers to this also as "significant work" or "important work". The
talk had as title "You and Your Research" and was given at the Morris
Research Center of Bellcore on March 7, 1986.
My source is a transcript
with abstract and introduction by J.F. Kaiser. The transcript not only
covers Hamming's talk, but also the introduction by Alan G. Chynoweth.
My copy does say whether it was published.
"You and Your Research" can
be organised by collecting together (see the points below)
the observations about what makes
the difference between "those who did and those who might have done".
-
Luck
Hamming admits that luck plays a part. But I get the impression that he
considers it a minor part. Quotes Pasteur: "Luck favours the prepared
mind". And Newton who believed that he had thought harder about his
problems than anybody else.
-
Courage
It takes courage to think about important unsolved problems. (Excepting
of course the officially canonized problems, such as Hilbert's,
Fermat's Last Theorem, P = NP, ...). But the solutions that made a
difference were to problems that not were recognized as such and those
who worked on them usually did not get encouragement. The first
success often changes a fumbling, diffident researcher into a
courageous one. Hamming reflects about the lack of courage he
perceives in the generation after him, compared to that of his own. He
ascribes the greater amount of courage to the enormous confidence
gained from the experience of emerging from a tight spot in the second
world war to a glorious victory, and working hard at it. He doesn't
blame the present generation, though, and acknowledges that their
experience is very different.
-
Age
Here is one reason why people switch off after the first big success:
after that it is hard to work on small problems. Einstein in his later
years is an example: there was no way he could have had success in
unified field theory. Hamming submits that Shannon suffered the same
fate. In Hamming's opinion, the Institute of Advanced Study in
Princeton has ruined a lot of careers. (Feynman has a similar opinion.)
Because of this effect, the false impression is created that one can
only do great things when young. Hamming advocates change of field at
least every ten years. Even though he made a great contribution in
error-correcting codes, he stopped reading papers in this area after a
time. He acknowledges the difficulty in starting as a nobody in a new
field. But of course the new field should be sufficiently closely
related scientifically. Sociologically it will be disjoint.
-
Working conditions
Poor working conditions can be used creatively to lead to original
solutions. Hamming mentions as an example that Bell Labs did not have
acres of programmers. This prevented some projects and forced others,
more worthwhile ones, into existence.
-
Drive
Mentions the "compound interest effect": if one person works ten
percent more than another, the difference accumulates compounded
because, if you know more, then you learn more. Hamming does not
mention brains as what distinguishes the great scientists, but does
believe that it is Drive. A brighter worker who only dabbles in a topic
does not get anywhere; a less bright one who is committed is often
successful. It helps to corner yourself by making commitments public.
Hamming attributes a lot of good work to the drive exhibited by a
cornered rat.
-
Ambiguity
You should believe a theory enough to benefit from it. You should be
aware of its deficiencies at the same time, so you are ready to come up
with a better one when the opportunity presents itself. This is the
kind of ambiguity necessary for good scientific work that a lot of
people fail to cultivate.
-
Subconscious
It happens that someone wakes up in the morning and suddenly has the
solution to a problem. The unconscious has done the work while
sleeping. This only happens if the unconscious has nothing else to
work on. Hence, Hamming says, "keep your unconscious starved". Another
form of Drive or Commitment.
-
Important Problems
If you don't choose an Important Problem, then you can't do Important
Work. Too few people take the time to determine what problems are
important. Hamming has for many years devoted Friday afternoons to
"Great Thoughts Time". Samples: What will the role of computers be in
all of AT&T? How will computers change science? The trick is to find
the right kind of Important Problems. Time travel, teleportation and
antigravity are important in some sense, but not the right kind.
-
Open doors
Hamming feels that people keeping the door to their offices closed may
get more work done in the short run, but in the long run don't get as
far as they might because they tend to misapply their effort as a
result of not being in touch.
-
The way in which you do it
Hamming had a service job: to do computations for the scientists at
Bell Labs. By paying attention to the way in which he did the jobs he
did significant scientific work. This often involved re-doing the job,
getting the same figures, but in a cleaner way. One of the cleaner ways
became Hamming's Method for the integration of differential equations.
-
Selling the work
The work not only has to be done, but it also has to be published. It
not only has to be published, but also has to be read. Most papers pay
too much attention to the technical details of the contribution itself.
Potential readers can't follow it. The papers that get read pay more
attention to background and less to the contribution itself. Making
sure that people pay attention is called "selling the work" by Hamming.
To do this you have to learn to write clearly, give good formal talks,
and to give good informal talks. Hamming estimates that about as much
work should be spent on polish and presentation as on the work itself.
-
Educate your boss
Sometimes you should. Sometimes you can.
-
Use the system
The "system" being secretaries, technicians, bureaucrats, etc. A lot of
scientists fight it. Using it can give great results, but requires some
effort or other measures that are distasteful to many scientists.
-
Is it worth it?
The required drive and commitment comes at the expense of other things.
Hamming thinks it's worth it, although the "other things" included in
his case his health.
-
Stimulation
Seek out the Greats and be stimulated by them. Avoid "sound absorbers":
people who may absorb ideas, but do not stimulate in return.
-
Library work
Those who do too little don't get anywhere. Those who do too much don't
get anywhere either.
-
Research or management?
That depends on your vision. If you have a vision about, say, the role
of mathematics in Bell Labs, then the only way to make it happen is to
become the head of the mathematics department. Hamming never went into
a management position.
