If there is one simple distinction between science and foolishness, I think it is this: Science takes the mundane and makes it wonderful; foolishness takes the wonderful and makes it merely mysterious.
Penn and Teller have a perfect example of how this works. In
most of their road shows, they have one illusion that they do the
usual way and then repeat with the mechanism explained. One that
they have done several times is a kind of expansion of the "woman
sawed in half." As an illusion, you see a set of painted boxes
with little doors here and there. Teller gets inside, Penn
rearranges the boxes and, on a musical cue, a door flips open to
show a foot or a hand or Teller's face. As the music goes on the
rearrangements get more impossible but there is never a missed
cue. There you are, faced with a mystery; how'd they
They repeat the trick with transparent boxes. This time, you can
see exactly how it's done, with Teller slithering here and
scooting there inside the boxes; it turns out that the hand you
see is occasionally Penn's. It's utterly mundane and completely
obvious and totally wonderful. All the mystery is gone. It
doesn't spoil anything. The feeling that replaces it, that
combination of "Oh, wow!" and "Ah ha!," that rush, is the special
sense of wonder that comes with seeing an entire mechanism laid
bare for the very first time.
I think that the rush is really why people do science. The next
best thing is explaining something so well that you see "Ah ha!"
in another's eyes.
True, few of us have the opportunity either to do original
science or to teach in a traditional setting. Any of us,
however, can get the same rush of discovery from study and any of
us can get the rush of teaching from explaining one thing well to
one other person. "Good Science Simply Explained" is a nice
little sound-bite of a goal and it offers an opportunity to learn
something, teach something and get a rush all at the same time.
Not bad, but explain just what to whom?
Perhaps the best audience is the honestly curious, non-credulous
but uninformed person, one of the proverbially "open-minded," for
that person is the most likely future victim of mystery.
There's nothing wrong with mystery as such. It gets the juices
going, gets us thinking, gets us trying to solve a problem.
However, when some guru of foolishness tells a person that some
things are meant to remain mysteries, that some things cannot or
ought not to be investigated -- when someone hears that and
believes it -- that person is diminished. That's a battle worth
fighting.
Given a worthy audience, what is a good topic? Some kinds of
foolishness, things like astrology, UFOs and creationism, are
simply laughable. It's unlikely that anyone will change the
minds of the people who believe in these things since, deny it
though they will, they are acting out of faith. However, because
they argue faith as a matter of fact, other facts are potent
weapons. The battle is worth fighting not so much to convince
the believer as to supply the rational alternative to the
honestly curious. That's why the detailed critical work, what's
often called debunking, is so very valuable and necessary.
Many of us feel that we don't have a big problem in dealing with
laughable foolishness because most of this stuff doesn't even
make the grade as pseudoscience. It doesn't take too long to
decide if the person we're dealing with is honestly curious or a
true believer; but either way, there is something particularly
aggravating in dealing with this kind of foolishness. I think
this is because virtually all of the arguments are inductive:
identify a thousand UFOs and a believer points to the thousand
and first sighting; analyze the tears of a hundred weeping
statues as olive oil and a believer can both acknowledge that and
still claim that the one you didn't analyze is the real thing.
The lack of closure fundamental to induction is the wedge that
the believer hammers on to keep the argument forever open. It
takes a strong stomach and an even temper to deal with this
mindset.
A topic that might be a little more in line with the goal here is
a small but disturbing category of pseudoscience. Its argument
sounds plausible, it looks like it's based in fact, it doesn't
seem to deal with unconventional science most of the time and yet
we're sure it's wrong from the first hearing. These things are
often alternative physical theories or gadgets: stuff like
perpetual motion machines, home-built anti-gravity devices, and
faster-than-light drives. These can be a most embarrassing
problem when they catch us unaware because here
That is a most uncomfortable place in which to be. "Why won't
this particular over-unity machine work?" asks an honestly
curious person. "Violates the second law of thermodynamics," we
respond. "Why can't we travel faster than light," asks another.
"Violates special relativity," we say. Hmm ... and just what
bible are
It takes a little work to counter one of these things but the
reward is that it can be done definitively because it can be done
deductively. These pretty little bits of pseudotheory carry the
seeds of their own destruction because they are based on the
facts of accepted (believers call it Establishment) science.
It's possible to start with that fact, add the facts that have
been ignored, correct the errors in methodology and establish a
deductive train of logic that follows from the same source and
handily refutes the pseudotheory. It's very satisfying and a lot
of fun.
The errors in these things fall into two categories: matters of
fact and matters of methodology. Matters of fact are seldom
disputed in pseudotheories; they are just used selectively.
Things like the mass of the Sun, the speed of light or the charge
of the electron are easy enough to look up. In matters of
methodology it's a little more difficult to point at a specific
reference.
Scientific method is a lot more complex than the six-paragraph
five-step distillation of Bacon we've all seen at the beginning
of some textbook. There are works specific to the subject
(Popper and Kuhn leap to mind) but, as with so many other things,
the best way to learn it is to do it. A good way to learn how to
do it is to watch it being done and scientific biographies and
primary sources are a great way to get a bird's eye view of
scientific method as it happens.
Scientific biographies -- works like Pais on Einstein, Westfall
on Newton or Sime on Meitner -- combine the story of a life with
the story of the life's work. Unlike the more common historical
biography, the emphasis is on the work: where did the ideas come
from and how did they grow? The stories can be centuries apart,
but they all have one thing in common: good scientists have a
childlike sense of wonder. They know how to ask an innocent and
truly open-minded "Why?" Great scientists (in the vernacular of
the trade those that "have a knack for picking the right
problems") ask the most profound whys. These are questions like
Bethe's "Why does the Sun shine?," Rayleigh's "Why is the sky
blue?," and Olber's "Why is the night dark?"
Primary sources are the works these scientists wrote themselves
in which they answer these questions for the very first time.
The very best scientists can not only ask childlike questions but
also answer them in the same spirit. They are the very best
explainers of their ideas. Galileo did not rant at the church in
writings like ; he
explained things to Simplicio, Everyman, in a dialogue.
Einstein's fundamental work never was "understandable to only
four people on the planet." That's mystery talking. His
popular explanation of relativity is still in print -- in
paperback, no less -- and eminently accessible to anyone with a
high school education (perhaps even a modern one) and a
willingness to turn off the TV for a few nights. A lot of his
scientific work is equally simple and accessible. (The mass-
energy proof, for example, is barely three pages long and, again,
it requires no more than a high school education to follow it.)
All the greats, every one of them, had to explain fundamentally
new ideas to people who had never heard them before. They are
remembered not only because they thought the thoughts but also
because they succeeded in explaining them.
It may be an exaggeration, but it seems to me that the
pseudotheories are born of people who learned all of their
science only from textbooks. There is the same mile-wide inch-
deep cover-the-material-quickly feel to them that you get from
the typical textbook. That's something to remember the next time
you crack open Thus and Such's
