## Entropia
Entropia: amnésia termodinâmica.
## Temperatura do inferno
The temperature of Heaven can be rather accurately computed from available
data. Our authority is Isaiah 30:26, "Moreover, the light of the Moon
shall be as the light of the Sun and the light of the Sun shall be
sevenfold, as the light of seven days." Thus Heaven receives from the Moon as much
radiation as we do from the Sun, and in addition seven times seven (49)
times as much as the Earth does from the Sun, or fifty times in all. The light
we receive from the Moon is one ten-thousandth of the light we receive from
the Sun, so we can ignore that. With these data we can compute the
temperature of Heaven. The radiation falling on Heaven will heat it to the point
where the heat lost by radiation is just equal to the heat received by
radiation, i.e., Heaven loses fifty times as much heat as the Earth by radiation.
Using the Stefan-Boltzmann law for radiation, (H/E)^4 = 50, where E is the
absolute temperature of the earth (-300K), gives H as 798K (525C). The exact
temperature of Hell cannot be computed, but it must be less than 444.6C,
the temperature at which brimstone or sulphur changes from a liquid to a gas.
Revelations 21:8 says "But the fearful, and unbelieving ... shall have
their part in the lake which burneth with fire and brimstone." A lake of molten
brimstone means that its temperature must be at or below the boiling
point, or 444.6C (Above this point it would be a vapor, not a lake.) We have,
then, that Heaven, at 525C is hotter than Hell at 445C.

## Cavalos
Lemma: All horses are the same color.
Proof (by induction):
Case n = 1: In a set with only one horse, it is obvious that all
horses in that set are the same color.
Case n = k: Suppose you have a set of k+1 horses. Pull one of these
horses out of the set, so that you have k horses. Suppose that all
of these horses are the same color. Now put back the horse that you
took out, and pull out a different one. Suppose that all of the k
horses now in the set are the same color. Then the set of k+1 horses
are all the same color. We have k true => k+1 true; therefore all
horses are the same color.
Theorem: All horses have an infinite number of legs.
Proof (by intimidation):
Everyone would agree that all horses have an even number of legs.
It is also well-known that horses have forelegs in front and two legs
in back. 4 + 2 = 6 legs, which is certainly an odd number of legs
for a horse to have! Now the only number that is both even and odd is
infinity; therefore all horses have an infinite number of legs.
However, suppose that there is a horse somewhere that does not
have an infinite number of legs. Well, that would be a horse of a
different color; and by the Lemma, it doesn't exist.

## Intuição
The only "intuitive" interface is the nipple. After that, it's all
learned.
-- Bruce Ediger, bediger@teal.csn.org, on X interfaces
## Kermit
"We invented a new protocol and called it Kermit, after Kermit the Frog,
star of "The Muppet Show." [3]
[3] Why? Mostly because there was a Muppets calendar on the wall when we
were trying to think of a name, and Kermit is a pleasant, unassuming sort
of character. But since we weren't sure whether it was OK to name our
protocol after this popular television and movie star, we pretended that
KERMIT was an acronym; unfortunately, we could never find a good set of
words to go with the letters, as readers of some of our early source code
can attest. Later, while looking through a name book for his forthcoming
baby, Bill Catchings noticed that "Kermit" was a Celtic word for "free",
which is what all Kermit programs should be, and words to this effect
replaced the strained acronyms in our source code (Bill's baby turned out
to be a girl, so he had to name her Becky instead). When BYTE Magazine
was preparing our 1984 Kermit article for publication, they suggested we
contact Henson Associates Inc. for permission to say that we did indeed
name the protocol after Kermit the Frog. Permission was kindly granted,
and now the real story can be told. I resisted the temptation, however,
to call the present work "Kermit the Book."

## DECWARS
After sifting through the overwritten remaining blocks of Luke's home
directory, Luke and PDP-1 sped away from /u/lars, across the surface of the
Winchester riding Luke's flying read/write head. PDP-1 had Luke stop at the
edge of the cylinder overlooking /usr/spool/uucp.
"Unix-to-Unix Copy Program;" said PDP-1. "You will never find a more
wretched hive of bugs and flamers. We must be cautious."

## Certo e errado
Só que o erro maior é justamente ficar procurando os erros...
Ou, citando Casa das Máquinas:
"Certo sim, seu errado, certo sim, seu errado...."
A mother mouse was taking her large brood for a stroll across the kitchen
floor one day when the local cat, by a feat of stealth unusual even for
its species, managed to trap them in a corner. The children cowered,
terrified by this fearsome beast, plaintively crying, "Help, Mother!
Save us! Save us! We're scared, Mother!"
Mother Mouse, with the hopeless valor of a parent protecting its
children, turned with her teeth bared to the cat, towering huge above them,
and suddenly began to bark in a fashion that would have done any Doberman
proud. The startled cat fled in fear for its life.
As her grateful offspring flocked around her shouting "Oh, Mother,
you saved us!" and "Yay! You scared the cat away!" she turned to them
purposefully and declared, "You see how useful it is to know a second
language?"
I went on to test the program in every way I could devise. I strained it to
expose its weaknesses. I ran it for high-mass stars and low-mass stars, for
stars born exceedingly hot and those born relatively cold. I ran it assuming
the superfluid currents beneath the crust to be absent -- not because I wanted
to know the answer, but because I had developed an intuitive feel for the
answer in this particular case. Finally I got a run in which the computer
showed the pulsar's temperature to be less than absolute zero. I had found
an error. I chased down the error and fixed it. Now I had improved the
program to the point where it would not run at all.

Of Pulsars, Black Holes and the Fate of Stars"
All life evolves by the differential survival of replicating entities.
-- Dawkins
MAN:
An animal so lost in rapturous contemplation of what he thinks he
is as to overlook what he indubitably ought to be. His chief
occupation is extermination of other animals and his own species,
which, however, multiplies with such insistent rapidity as to infest
the whole habitable earth and Canada.

Murphy's Law is recursive. Washing your car to make it rain doesn't work.
## Murphy as a proletarian
"Murphy's Law, that brash proletarian restatement of Godel's Theorem ..."
-- Thomas Pynchon, "Gravity's Rainbow"
## Civilization
It is better for civilization to be going down the drain than to be
coming up it.
-- Henry Allen
We are all agreed that your theory is crazy. The question which
divides us is whether it is crazy enough to have a chance of being
correct. My own feeling is that it is not crazy enough.
-- Niels Bohr
Ginsberg's Theorem:
1. You can't win.
2. You can't break even.
3. You can't even quit the game.
Every major philosophy that attempts to make life seem
meaningful is based on the negation of one part of Ginsberg's
Theorem. To wit:
1. Capitalism is based on the assumption that you can win.
2. Socialism is based on the assumption that you can break even.
3. Mysticism is based on the assumption that you can quit the game.

I think computer viruses should count as life. I think it says something about human nature that the only form of
life we have created so far is purely destructive. We've created life in our own image. Stephen Hawking

Velilind's Laws of Experimentation:
1. If reproducibility may be a problem, conduct the test only once.
2. If a straight line fit is required, obtain only two data points.
The three laws of thermodynamics:
(1) You can't get anything without working for it.
(2) The most you can accomplish by working is to break even.
(3) You can only break even at absolute zero.
The bureaucracy is expanding to meet the needs of an expanding
bureaucracy.
"Violence is the last refuge of the incompetent." -- Asimov, Foundation
If a nation values anything more than freedom, it will lose its freedom;
and the irony of it is that if it is comfort or money it values more, it
will lose that, too.
-- W. Somerset Maugham
Our congratulations go to a Burlington Vermont civilian employee of the
local Army National Guard base. He recently received a substational cash
award from our government for inventing a device for optical scanning.
His device reportedly will save the government more than $6 million a year
by replacing a more expensive helicopter maintenance tool with his own,
home-made, hand-held model.
Not suprisingly, we also have a couple of money-saving ideas that we submit
to the Pentagon free of charge:
a. Don't kill anybody.
b. Don't build things that do.
c. And don't pay other people to kill anybody.
We expect annual savings to be in the billions.

An American scientist once visited the offices of the great Nobel prize
winning physicist, Niels Bohr, in Copenhagen. He was amazed to find that
over Bohr's desk was a horseshoe, securely nailed to the wall, with the
open end up in the approved manner (so it would catch the good luck and not
let it spill out). The American said with a nervous laugh,
"Surely you don't believe the horseshoe will bring you good luck,
do you, Professor Bohr? After all, as a scientist --"
Bohr chuckled.
"I believe no such thing, my good friend. Not at all. I am
scarcely likely to believe in such foolish nonsense. However, I am told
that a horseshoe will bring you good luck whether you believe in it or not."
OCCAM'S ERASER:
The philosophical principle that even the simplest
solution is bound to have something wrong with it.
Everything you've learned in school as "obvious" becomes less and less
obvious as you begin to study the universe. For example, there are no
solids in the universe. There's not even a suggestion of a solid.
There are no absolute continuums. There are no surfaces. There are no
straight lines.
-- R. Buckminster Fuller
Brooke's Law:
Whenever a system becomes completely defined, some damn fool
discovers something which either abolishes the system or
expands it beyond recognition.
"The illegal we do immediately. The unconstitutional takes a bit

Silverman's Law:
If Murphy's Law can go wrong, it will.
Dirac was a committed (Someone who denies the existence of god) atheist. After being asked about his thoughts on Dirac's views, (United States physicist (born in Austria) who proposed the exclusion principle (thus providing a theoretical basis for the periodic table) (1900-1958)) Pauli remarked "If I understand Dirac correctly, his meaning is this: there is no God, and Dirac is his Prophet".

After 35 years, I have finished a comprehensive study of European
comparative law. In Germany, under the law, everything is prohibited,
except that which is permitted. In France, under the law, everything
is permitted, except that which is prohibited. In the Soviet Union,
under the law, everything is prohibited, including that which is
permitted. And in Italy, under the law, everything is permitted,
especially that which is prohibited.

A cloud does not know why it moves in just such a direction and at such
a speed, if feels an impulsion... this is the place to go now. But the
sky knows the reasons and the patterns behind all clouds, and you will
know, too, when you lift yourself high enough to see beyond horizons.
-- Messiah's Handbook : Reminders for the Advanced Soul
There are three schools of magic. One: State a tautology, then ring
the changes on its corollaries; that's philosophy. Two: Record many
facts. Try to find a pattern. Then make a wrong guess at the next
fact; that's science. Three: Be aware that you live in a malevolent
Universe controlled by Murphy's Law, sometimes offset by Brewster's
Factor; that's engineering.

Gerrold's Laws of Infernal Dynamics:
1) An object in motion will always be headed in the wrong direction.
2) An object at rest will always be in the wrong place.
3) The energy required to change either one of these states
will always be more than you wish to expend, but never so
much as to make the task totally impossible.

When you pull a plastic garbage bag from its handy dispenser

Quando ocorrem variações no câmbio, queda nas bolsas de valores, variações
nas taxas de juros ou pequenos distúrbios na economia, rapidamente os governos

Everyone knows that dragons don't exist. But while this simplistic
formulation may satisfy the layman, it does not suffice for the
scientific mind. The School of Higher Neantical Nillity is in fact
wholly unconcerned with what DOES exist. Indeed, the banality of
existence has been so amply demonstrated, there is no need for us
to discuss it any further here. The brilliant Cerebron, attacking
the problem analytically, discovered three distinct kinds of dragon:
the mythical, the chimerical, and the purely hypothetical. They were
all, one might say, nonexistent, but each nonexisted in an entirely
different way...
