Advice to the Young Astronomer
by Ed Nather
- Go into some other profession
- Consider being a Rock Star. It pays very well, and does not
demand much in the way of talent, other than a willingness to
dress really strangely, act like a manic 5 year old trying to
get Mommy's undivided attention, and make a lot of noise.
Perks include unprecedented access to sex and drugs, and the
quiet satisfaction that you are making a lasting contribution
to society.
- How about politics? It also pays well and requires nothing in the
way of education or talent. If you are inherently honest, however,
that could create problems, since then you would not fit in very
well with those already in the business.
- You might try astrology. Most people confuse this with astronomy anyway, since it involves the stars, and anything you might already have learned about them would not be wasted. Some talent is needed: you must be able to present nonsense in a sincere, convincing way. If you insist on being an academic, you could espouse Creation Science, but it would be harder to keep a straight face.

- If nothing will satisfy you except doing astronomy, then plan your
graduate career and subsequent job-hunting with some care, since there
aren't many research jobs to be had, and the available ones don't pay
very well. Are you sure you want to do this?
- About half of the advertised jobs in astronomy mention that experience
with instrumentation of some kind is desirable, if not essential. Just
knowing how to surf the internet is not enough, since any 6-year-old
can do that; you need to know something about optics, electronics, and
real-time programming to be able to build anything useful and get it to
work. Note that a shallow acquaintance with these skills, so you can
talk to a technician or programmer to get what you want, does not work.
Learn to do it yourself, first. Make something, then try to use it to
take data. You'll understand far more after klutzing around a bit than
you ever will in a formal design course. Learn from others who know
how to do these things, read books about them, but above all do them
yourself. Having a professional design the instrument for you will get
you a skilled, polished, economical design that solves the wrong problem.
- After the relief and euphoria that follows a successful thesis defense
has worn off, you'll need to find a job. It may be too late already.
Why did you wait until you were finished? Get your advisor to help
by asking his friends about job openings, if you are still on speaking
terms with him. You are far more likely to get a job if there is
someone who knows about you, and wants you to have it, than if you come
in cold. Every applicant looks good on paper so it's hard to choose.
A friend on the search committee is worth 10 refereed research papers
on your resume'. Unjust? Sure. Welcome to planet Earth.
- It has been my experience that groups of people who form entities -
companies, university departments, whatever - will hire you to do
a job and then do everything they can to keep you from doing it. They
have rules. You will have to learn your way around these things to
get anything done. Do not be deceived by organization charts: nobody
follows them. Find out who really is in charge, and make friends with
them. Be totally shameless: pay for the beer, and listen attentively
when they whine. Bureaucracies are the same all over the world: they
want you to follow the rules, and they don't care if you never get
anything done. If you must break their rules (and you must) then give
them something on paper so they won't get blamed. It is always easier
to get forgiveness than permission.
- The bureaucratic hierarchy in a university begins with the Department
Chairman or Observatory Director and goes up from there. If you want
to be a research scientist never accept one of these positions under
any circumstances - it's the end of research if you do. A good
chairman will protect you from the Administration who think they can
correct imperfections by passing new rules for everyone to follow;
he will intercept these things, or deflect them, and let you get on with
your work. Cherish the good chairmen: they are rare.
- Committee assignments: the theory here is that everybody should share
in the burden of administration, taking time away from their research
work in the process. If you are very good and conscientious about
this stuff you will be given more and more of it, since you get things
done, to the lasting benefit of the department administrators. On the
other hand if you thoroughly neglect it, fail to call or attend any
committee meetings, and generally do a lousy job, you will get fewer
and fewer committee assignments, and you can get on with your research.
You should not be too blatant, though. When pressed, have a meeting by
email - just send each committee member a copy of the topic to be
considered (obscurity here is a virtue) and ask them to respond. Make a
single file of all the individual responses and send it back to all of
them, and a copy to the department chairman. This should create enough
dissention and warring messages that you can tell the chairman you are
uncomfortable making a decision without a consensus, and that he had
better do it. You won't be assigned to that committee again.
- Tenure: Seek it. Job security is comforting, but the main point about
tenure is that you get to do what you want in the way of research. You
will probably have to pay for it yourself - you won't get departmental
funds after that business with the committee assignments - but you can
find grant funds if you know what you want to do and can describe it
well. You don't have to follow the "mainstream" of current astronomical
research, and you shouldn't. If your primary goal is to learn how the
universe really works, and not just to get your name in the newspaper,
look where others are not exploring. Nature is so rich you are unlikely
to look carefully at anything without learning something new,
particularly in unexplored territory. New instruments are wonderful
here. If you follow current fads in astronomy you'll just be wasting
your time - the fad-followers will publish what they find and you can
read about it, for free. If you have to rush to publish something, quick
before you get scooped, you are doing the wrong research. Stop it, and
do something nobody thinks is interesting. Trust me: it will be.
- Teaching: Learn from it. Rutherford's adage - that if you can't explain
to a barmaid in five minutes what you are doing, you don't really know
what you are doing - is true wisdom. Teaching a class on elementary
astronomy to undergraduates is the best way I know of to get the basic
ideas clearly in mind. If their eyes glaze over at some explanation, and
they fail to understand it, chances are you don't really understand it
either. It's hard to get enthusiastic about the Doppler shift after a
few years, but you can do it. Try doing it without mentioning waves.
You can; it works. In particular, cherish the questions students ask.
They may sound dumb, but they usually aren't - misinformed, maybe, or
naive, which can be corrected - and they are sometimes profound,
because the students are using their "common sense" - their own, unique
worldmodel - to formulate the question. I have received, gratefully,
several research ideas from the questions asked by undergraduate
non-science majors. Research institutions usually justify their
priorities with the argument that students benefit by learning directly
from the researchers themselves. No argument, but they rarely mention
that it is a two way street. The idea about the two sets of rules in
physics - one set for the future and one for the past - came to me
while I was rehearsing an undergraduate lecture on quantum mechanics in
the shower.
- Research: Do whatever you burn to do. If your innate curiosity doesn't
burn to learn about it, perhaps it's not so important. Passion is the
key, not mild curiosity. Further, try to keep a mental file of all the
astronomical problems you know about, along with a file of things you
have real doubts about, even though it may be standard dogma. My mental
image of such files is like a row of small baskets, each with its own
problem, with a red flag in front of each one. When I learn something
new, or hear of a new technology that might be made into a new
instrument, I go down the line of flags with it, poking at each one to
see if any one them give - that is, might now be solved or explored
with the new idea in hand.
- Keep a mental file of research work that will probably pay off, along
with a file of how to do it - what instrument to use or build, what
measurements to make, how to extract the physics from the data. If
you do this routinely, you will end up with a file of more useful
research than you can do in a lifetime. When the opportunity arises
(e.g. when you have a student looking for a project) give the idea
away. If someone else uses it to learn more about the universe, then
you will know it too, and you didn't even have to do the work! I
have encountered astronomers who like to keep their ideas secret, and
not tell anybody, so they can work on them themselves, and get all the
glory and credit. I've never understood this. I guess they think they
may never have another good research idea, so they covet what they have.
In my experience, you can give them away with both hands and still have
more than you can ever pursue yourself.
- Discoveries: Make them. Newton said he solved problems by keeping
them "...continually before the mind" - that is, by thinking about
them all the time, any time, when you aren't preoccupied with doing
something else. When I am on autopilot - in the shower, driving to
work, in a committee meeting - I usually have a problem I'm thinking
about. I wake up with it in mind, and go to sleep with it in mind.
I don't solve all of them, but every once in a while I do: all the
puzzlements, the disconnected fragments that seem relevant, fall into
place, and I see that one basic idea can fit them all, comfortably,
with no fragments left over. This is sometimes called the "Aha!"
experience, and it is wonderful. You suddenly understand something
that was mysterious before, it all fits nicely into your worldmodel,
and you can now connect it with everything else you know. Once in a
while it will be new - that is, will be something nobody else knows.
Then the satisfaction of having found it out is really intense, and
is the basic reward from doing astronomy in the first place. There
is no feeling quite like it.
- Careful, now. Be sure it's right, that you can not only defend it,
but that you can explain it simply. Also make sure you have not
found it just because you wanted to, because you were sure that nature
worked this way. Make sure it's really so and you can prove it.
Read the history of astronomy so you won't be condemned to repeat it.
Look up William Pickering, who thought the moons of Jupiter were
elliptical and talked a lot of other (visual) observers into believing
it too. Remember Percival Lowell and his canals on Mars. Read about
the precession of the orbit of Mercury, and how it was "solved" by
finding the planet Vulcan as the nearest planet to the sun. If you
really expected nature to behave as you have just found, be doubly
suspicious. But if it's both new and right, practice how you will
explain it to Rutherford's barmaid in less than five minutes -
they are more rushed now than they were then, and probably less
interested in science.
- Above all, have fun.
