Science and Engineering Compared to the Arts and Humanities
The arts and the humanities give our lives meaning,
but science and engineering give us the means to
live. Engineering supplies new tools for living, while
science offers us new ways of thinking. The enemy
has always been ignorance, not science and
engineering. Technology has serious problems, yes.
But the alternatives are worse.

- Cartoon Laws
- Any body suspended in space will remain in space until made
aware of its situation.
Daffy Duck steps off a cliff, expecting further pastureland.
He loiters in midair, soliloquizing flippantly, until he
chances to look down. At this point, the familiar principle
of 32 feet per second per second takes over.
- Any body in motion will tend to remain in motion until solid matter
Whether shot from a cannon or in hot pursuit on foot, cartoon
characters are so absolute in their momentum that only a
telephone pole or an outsize boulder retards their forward
motion absolutely. Sir Isaac Newton called this sudden
termination of motion the stooge's surcease.
- Any body passing through solid matter will leave a perforation
conforming to its perimeter.
Also called the silhouette of passage, this phenomenon is the
speciality of victims of directed-pressure explosions and of
reckless cowards who are so eager to escape that they exit
directly through the wall of a house, leaving a cookie-cutout-
perfect hole. The threat of skunks or matrimony often
catalyzes this reaction.
- The time required for an object to fall twenty stories is greater
than or equal to the time it takes for whoever knocked it off the
ledge to spiral down twenty flights to attempt to capture it unbroken.
Such an object is inevitably priceless, the attempt to capture
it inevitably unsuccessful.
- All principles of gravity are negated by fear.
Psychic forces are sufficient in most bodies for a shock to
propel them directly away from the earth's surface. A spooky
noise or an adversary's signature sound will induce motion
upward, usually to the cradle of a chandelier, a treetop, or
the crest of a flagpole. The feet of a character who is
running or the wheels of a speeding auto need never touch
the ground, especially when in flight.
- As speed increases, objects can be in several places at once.
This is particularly true of tooth-and-claw fights, in
which a character's head may be glimpsed emerging from the
cloud of altercation at several places simultaneously. This
effect is common as well among bodies that are spinning or
being throttled. A 'wacky' character has the option of self-
replication only at manic high speeds and may ricochet off
walls to achieve the velocity required.
- Certain bodies can pass through solid walls painted to resemble
tunnel entrances; others cannot.
This trompe l'oeil inconsistency has baffled generation, but
at least it is known that whoever paints an entrance on a
wall's surface to trick an opponent will be unable to pursue
him into this theoretical space. The painter is flattened
against the wall when he attempts to follow into the painting.
This is ultimately a problem of art, not of science.
- Any violent rearrangement of feline matter is impermanent.
Cartoon cats possess even more deaths than the traditional
nine lives might comfortably afford. They can be decimated,
spliced, splayed, accordion-pleated, spindled, or
disassembled, but they cannot be destroyed.
After a few moments of blinking self pity, they reinflate,
elongate, snap back, or solidify.
Corollary: A cat will assume the shape of its container.
- For every vengeance there is an equal and opposite revengeance.
This is the one law of animated cartoon motion that also
applies to the physical world at large. For that reason,
we need the relief of watching it happen to a duck instead.
- Everything falls faster than an anvil.

- Extended Epstein-Heisenberg Principle:
- In an R & D orbit, only 2 of the existing 3 parameters can be defined
simultaneously. The parameters are: task, time, and resources ($).
1) If one knows what the task is, and there is a time limit allowed for
the completion of the task, then one cannot guess how much it will
2) If the time and resources ($) are clearly defined, then it is
impossible to know what part of the R & D task will be performed.
3) If you are given a clearly defined R & D goal and a definte amount
of money which has been calculated to be necessary for the completion
of the task, one cannot predict if and when the goal will be reached.
4) If one is lucky enough to be able to accurately define all three
parameters, then what one is dealing with is not in the realm of
R & D.

- A bureaucrat's castle is his desk . . . and parking place. Proceed
cautiously when changing either.
- On the theory that one should never take anything for granted, follow
up on everything, but especially those items varying from the norm.
The greater the divergence from normal routine and/or the greater the
number of offices potentially involved, the better the chance a
never-to-be-discovered person will file the problem away in a drawer
specifically designed for items requiring a decision.
- Never say without qualification that your activity has sufficient
space, money, staff, etc.
- Always distrust offices not under your jurisdiction which say that
they are there to serve you. "Support" offices in a bureaucracy tend
to grow in size and make demands on you out of proportion to their
service, and in the end require more effort on your part than their
service is worth.
Support organizations can always prove success by showing service to
someone . . . not necessarily you.

- The information you need is not what you can obtain.
- The information you can obtain costs more than you want to pay.
- Finagle's Rules:
- Ever since the first scientific experiment, man has been plagued by the
increasing antagonism of nature. It seems only right that nature should
be logical and neat, but experience has shown that this is not the case.

accept the pigheadedness of nature.

certainty it will be struck. (Remember: The disk is positive; cops
and old ladies are clearly negative.)
- The best catches are never seen. ("Did you see that?" "See what?")
- The greatest single aid to distance is for the disc to be going in a
direction you did not want. (Wrong way = long way.)
- The most powerful hex words in the sport are: "I really have this
down -- watch." (Know it? Blow it!)
- In any crowd of spectators at least one will suggest that razor
blades could be attached to the disc. ("You could maim and kill
with that thing.")
- The greater your need to make a good catch, the greater the
probability your partner will deliver his worst throw. (If you
can't touch it, you can't trick it.)

- While bryophytic plants are typically encountered in substrata of earthy
or mineral matter in concreted state, discrete substrata elements
occasionally display a roughly spherical configuration which, in
presence of suitable gravitational and other effects, lends itself to
combined translatory and rotational motion. One notices in such cases
an absence of the otherwise typical accretion of bryophyta. We conclude
therefore that a rolling stone gathers no moss.

- Issawi's Law of Dogmatism:
- When we call others dogmatic, what we really object to is their holding
dogmas that are different from our own.
- Issawi's Law of Estimation of Error:
- Experts in advanced countries underestimate by a factor of 2 to 4 the
ability of people in underdeveloped countries to do anything technical.
- Issawi's Law of Frustration:
- One cannot make an omelette without breaking eggs -- but it is amazing
how many eggs one can break without making a decent omelette.
- Issawi's Laws of Progress:
- The Course of Progress:
Most things get steadily worse.
- The Path of Progress:
A shortcut is the longest distance between two points.

- By the time a social science theory is formulated in such a way that it
can be tested, changing circumstances have already made it obsolete.
- Issawi's Observation on the Consumption of Paper:
- Each system has its own way of consuming vast amounts of paper: in
socialist societies by filling large forms in quadruplicate, in
capitalist societies by putting up huge posters and wrapping every
article in four layers of cardboard.

- Jaroslovsky's Law:
- The distance you have to park from your apartment increases in
proportion to the weight of packages you are carrying.
- Jay's Laws of Leadership:
- Changing things is central to leadership, and changing them before
anyone else is creativity.
- To build something that endures, it is of the greatest important to
have a long tenure in office -- to rule for many years. You can
achieve a quick success in a year or two, but nearly all of the great
tycoons have continued their building much longer.
- Jenkinson's Law:
- It won't work.
- Jinny's Law:
- There is no such thing as a short beer. (As in, "I'm going to stop off
at Joe's for a short beer before on the way home.")
- John's Axiom:
- When your opponent is down, kick him.
- John's Collateral Corollary:
- In order to get a loan you must first prove you don't need it.
- Johnson's First Law:

inconvenient possible time.

- If, in the course of several months, only three worthwhile social events
take place, they will all fall on the same evening.
- Johnson's Third Law:
- If you miss one issue of any magazine, it will be the issue containing
the article, story, or installment you were most anxious to read.

suggestions it's compromising.
- Kafka's Law:
- In the fight between you and the world, back the world.
- Kamin's First Law:
- All currencies will decrease in value and purchasing power over the long
term, unless they are freely and fully convertable into gold and that
gold is traded freely without restrictions of any kind.
- Kamin's Second Law:
- Threat of capital controls accelerates marginal capital outflows.
- Kamin's Third Law:
- Combined total taxation from all levels of government will always
increase (until the government is replaced by war or revolution).
- Kamin's Fourth Law:
- Government inflation is always worse than statistics indicate: central
bankers are biased toward inflation when the money unit is
non-convertible, and without gold or silver backing.
- Kamin's Fifth Law:
- Purchasing power of currency is always lost far more rapidly than ever
regained. (Those who expect even fluctuations in both directions play
a losing game.)
- Kamin's Sixth Law:
- When attempting to predict and forecast macro-economic moves or economic
legislation by a politician, never be misled by what he says; instead
watch what he does.

- Kaplan's Law of the Instrument:
- Give a small boy a hammer and he will find that everything he encounters
- Katz's Law:
- Men and nations will act rationally when all other possibilities have
- Katz's Maxims:
- Where are the calculations that go with the calculated risk?
- Inventing is easy for staff outfits. Stating a problem is much
harder. Instead of stating problems, people like to pass out half-
accurate statements together with half-available solutions which they
can't finish and which they want you to finish.
- Every organization is self-perpetuating. Don't ever ask an outfit to
justify itself, or you'll be covered with facts, figures, and fancy.
The criterion should rather be, "What will happen if the outfit stops
doing what it's doing?" The value of an organization is more easily
determined this way.
- Try to find out who's doing the work, not who's writing about it,
controlling it, or summarizing it.
- Watch out for formal briefings; they often produce an avalanche (a
high-level snow job of massive and overwhelming proportions).
- The difficulty of the coordination task often blinds one to the fact
that a fully coordinated piece of paper is not supposed to be either
the major or the final product of the organization, but it often
turns out that way.
- Most organizations can't hold more than one idea at a time. Thus
complementary ideas are always regarded as competetive. Further,
like a quantized pendulum, an organization can jump from one extreme
to the other, without ever going through the middle.
- Try to find the real tense of the report you are reading: Was it
done, is it being done, or is it something to be done? Reports are
now written in four tenses: past tense, present tense, future tense,
and pretense. Watch for novel uses of "contractor grammar", defined
by the imperfect past, the insufficient present, and the absolutely

- In dealing with OTHER people's problems, they are the world's most
- Kettering's Laws:
- If you want to kill any idea in the world today, get a committee
working on it.
- If you have always done it that way, it is probably wrong.
- Key to Status:
- S = D/K. S is the status of a person in an organization, D is the
number of doors he must open to perform his job, and K is the number of
keys he carries. A higher number denotes higher status. Thus the
janitor needs to open 20 doors and has 20 keys (S = 1), a secretary has
to open two doors with one key (S = 2), but the president never has to
carry any keys since there is always someone around to open doors for
him (with K = 0 and a high D, his S reaches infinity).
- Kharasch's Institutional Imperative:
- Every action or decision of an institution must be intended to keep the
institution machinery working.
The expert judgment of an institution, when the matter involved concerns
continuation of the institution's operations, is totally predictable,
and hence the finding is totally worthless.

- A patent application will be preceded by one week by a similar
application made by an independent worker.
- Firmness of delivery dates is inversely proportional to the
tightness of the schedule.

difficulty to assemble.

by blowing first.
- A failure will not appear until a unit has passed final inspection.
- A purchased component or instrument will meet its specs long enough,
and only long enough, to pass incoming inspection.
- After the last of 16 mounting screws has been removed from an access
cover, it will be discovered that the wrong access cover has been
- After an access cover has been secured by 16 hold-down screws, it
will be discovered that the gasket has been omitted.

found on the bench.

- Anticipated events never live up to expectations.
- That segment of the community with which one has the greatest
sympathy as a liberal inevitably turns out to be one of the most
narrow-minded and bigoted segments of the community.

a strong strain toward rationality. Therefore there is always the
possibility, in theory, of handling the wicked by outthinking them.

Good intentions randomize behavior.

- Always store beer in a dark place.
- Certainly the game is rigged. Don't let that stop you; if you don't
bet, you can't win.

- Always listen to experts. They'll tell you what can't be done, and
why. Then do it.
- If it can't be expressed in figures, it is not science; it is
- It has long been known that one horse can run faster than another --
but which one? Differences are crucial.
- A fake fortuneteller can be tolerated. But an authentic soothsayer
should be shot on sight. Cassandra did not get half the kicking
around she deserved.
- Delusions are often functional. A mother's opinions about her
children's beauty, intelligence, goodness, et cetera ad nauseam,
keep her from drowning them at birth.
- A generation which ignores history has no past -- and no future.
- A poet who reads his verse in public may have other nasty habits.
- Small change can often be found under seat cushions.
- History does not record anywhere at any time a religion that has any
rational basis. Religion is a crutch for people not strong enough
to stand up to the unknown without help. But, like dandruff, most
people do have a religion and spend time and money on it and seem to
derive considerable pleasure from fiddling with it.
- It's amazing how much "mature wisdom" resembles being too tired.

- Avoid making irrevocable decisions while tired or hungry.
- An elephant: A mouse built to government specifications.
- A zygote is a gamete's way of producing more gametes. This may be
the purpose of the universe.
- Stupidity cannot be cured with money, or through education, or by
legislation. Stupidity is not a sin; the victim can't help being
stupid. But stupidity is the only universal capital crime; the
sentence is death, there is no appeal, and execution is carried out
automatically and without pity.
- God is omnipotent, omniscient, and omnibenevolent. It says so right
here on the label. If you have a mind capable of believing all
three of these divine attributes simultaneously, I have a wonderful
bargain for you. No checks, please. Cash and in small bills.
- Beware of altruism. It is based on self-deception, the root of all
- The most preposterous notion that H. sapiens has ever dreamed up is
that the Lord God of Creation, Shaper and Ruler of all the Universe,
wants the saccharine adoration of His creatures, can be swayed by
their prayers, and becomes petulant if He does not receive this
flattery. Yet this absurd fantasy, without a shred of evidence to
bolster it, pays all the expenses of the oldest, largest, and least
productive industry in all history.

- Secrecy is the beginning of tyranny.
- The greatest productive force is human selfishness.
- Be wary of strong drink. It can make you shoot at tax collectors --
- Expertise in one field does not carry over into other fields. But
experts often think so. The narrower their field of knowledge the
more likely they are to think so.
- Never try to outstubborn a cat.
- Tilting at windmills hurts you more than the windmills.
- Yield to temptation; it may not pass your way again.
- Waking a person unnecessarily should not be considered a capital
crime. For a first offense, that is.
- The correct way to punctuate a sentence that starts: "Of course it's
none of my business, but . . . " is to place a period after the word
"but". Don't use excessive force in supplying such a moron with a
period. Cutting his throat is only a momentary pleasure and is
bound to get you talked about.

- Anything free is worth what you pay for it.
- Climate is what we expect; weather is what we get.
- Pessimist by policy, optimist by temperament -- it is possible to be
both. How? By never taking an unnecessary chance and by minimizing
risks you can't avoid. This permits you to play out the game
happily, untroubled by the certainty of the outcome.

think; they do not create.

This list represents a compilation from many sources, including slips of
unidentified paper and long-since-deleted electronic mail. Some sources,
however, provided significant enough contributions that they are remembered.
Foremost among these are (1) a list accumulated by veteran collector Conrad
Schneiker (formerly of U of Arizona, now believed to be at CDC in Sunnyvale) and
expanded by Ed Logg, Gregg Townshend, and John Ehrman, and (2) Paul Dickson's
excellent book, "The Official Rules", which I heartily recommend. Not only does
Dickson include many items that, for one reason or another, are omitted from
this list, but he also includes attributions wherever possible. (Some of his
attributions are known to be incorrect, but it's still amusing reading.)
