Huygens' Clock Puzzle Solved
PhotoGuy writes "Okay, I haven't heard of this puzzle either until now, but it sounds like a fascinating phenomenon. According to this article:Huygens had two clocks side by side and he found that even when they began out of sync, they soon got into a rhythm where the pendulum on one moved as if it were a mirror image of the other.The article is pretty light on the explanation, noting only the conditions required (small relative mass of the pendulums [pendula?], relatively close speed of the clocks), and not really addressing the physics behind it.
" There's a great site at Georgia Tech that explains the puzzle in more detail.

ugh - i've been using vbulletin too much!
Secondly, making Microsoft contribute financially to a site like this a good thing. Less money for closed source, more money for the community.
Not FEMA! Don't you know that they plan to overthrough the government and make us all into slaves?

Hmm. Where to? Can I come too? I can pay for the jukebox if you like.

Do you have any better hostages?
My experimentation shows that if you have a girl stand close to a very large clock, her period and the period of the clock will never fall into sync. Am I doing something wrong?
Ayn Rand and the perversion of libertarianism
The political controversy of the late 19th century was: whether
socialists (all those who believed in the individual's right to
possess what he or she produced) should engage in the political
process, seize control of the state, and use the state apparatus
to achieve liberation; or, whether a worker's state was inher-
ently contradictory, counter revolutionary, and would only lead
to the creation of a new ruling class whose interests would still
clash with those of the ruled that the state should be abolished
allowing for no transitional stage of any kind during which power
may have the chance to reconsolidate itself.
The situation has recreated itself with amazing similarity
almost exactly a century later.
Non-libertarian parties the world over (those who see authori-
tarian centralization the bulwark of civilization) are bankrupt,
economically and intellectually. The only viable intellectual
current today falls under that ambiguous term~ `libertarian'.
Today there exist beneath this umbrella as many splinter groups
as there were a hundred years ago under the umbrella of social-
ism. Two distinct trends, a right and a left if you will, are
clearly discernible.
One group, clearly the largest with a hierarchical organization
modeled on the other political parties, believes, like most
Marxists, in constitutional parliamentary republican democracy.
They believe that the state is a necessary guarantor of indi-
vidual safety and the product of the individual's labor, and in
gradual progress toward a free society through participation in
the political process.
The other group, much smaller and far more splintered, reject
the state as necessarily a tool of class domination and exploita-
tion.
This group believes that what Bakunin said a hundred years ago
is as true today, ``If you took the most ardent revolutionary,
vested him in absolute power, within a year he would be worse
than the Czar himself.''
The first group is in all fairness a direct inheritor of the
ideals of the American Revolution. In modern times, however, it
has only two roots: (1) the Austrian school of economics repre-
sented by Ludwig Von Mises; (2) the philosophy of Ayn Rand.
Von Mises never considered the libertarians. He answered the
Marxists and the Keynesians and defended laissez-faire capitalism
at a time when no one else would. His justification for capital-
ism was empirical~the greatest good for the greatest number.
Ayn Rand, however, attempted to offer a moral justification of
capitalism by substituting the word `capitalism' for the liber-
tarian meaning of the word `socialism'. She then attributed all
of the ills of capitalism to government interference with the
market and all of the world's wealth to the minds of the men whom
the world considered the robber barons.
The contrast between Ayn Rand's `Objectivism' and libertarian-
ism is deeper than mere substitution of terminology, however.
Several of her propositions or axioms place her clearly outside
of the libertarian tradition.
Her justification of the state is derived from a Hobbesian
state of nature theory:
``...a society without an organized government would be at the
mercy of the first criminal who came along and who would precipi-
tate it into chaos and gang warfare....'' [The Virtue of Selfish-
ness, 152; pb 112]
``If a society provided no organized protection against force,
it would compel every citizen to go about armed, to turn his home
into a fortress, to shoot any strangers approaching his door~or
to join a protective gang of citizens who would fight other
gangs, formed for the same purpose, and thus bring about the
degeneration of society into the chaos of gang rule, i.e., rule
by brute force, into perpetual warfare of prehistoric savages.''
[Ibid., 146; pb 108]
Ayn Rand's belief in the inherent depravity of human nature
which renders us forever incapable of living without rulers and
not descending to the level of `savages', clearly places her out-
side of the libertarian tradition which views human nature as es-
sentially good, capable of indefinite improvement through the
experience of freedom and the exercise of reason.
Her knowledge of anthropology is as embarrassing as her under-
standing of history. For example, in regards to her conception of
who are the savages, she describes America as, ``...a superlative
material achievement in the midst of an untouched wilderness,
against the resistance of savage tribes.'' [For The New Intellec-
tual, 58; pb 50]
To Rand, the essential characteristic of the state is that it
possesses a monopoly on the use of retaliatory force. How does
she justify this monopoly or national sovereignty? She accepts it
as a given, something not requiring a justification, and demands
that an-archy, the negation of the proposition, justify itself.
Her concept of national sovereignty is then something tran-
scendental, existing separate and apart from individuals. and
beyond the right of the individual to accept or reject according
to his or her own reason.
These propositions clearly place Ayn Rand's philosophy closer
to Hobbes, Hegel, and Marx, than to libertarianism.
The state, according to Miss Rand, must hold a monopoly on the
enforcement of contracts and the settling of disputes between
individuals, at least whenever this arbitration is not accepted
by both sides voluntarily. She fails to consider that the en-
forcement of contracts by the state fundamentally alters the
nature of free agreements. Agreements are made on terms which
otherwise might not be, because they are justiciable.
The terms of ``free agreements'' under law are titled in favor
of lenders over debtors, landlords over tenants, employers over
employees, in a way which would not exist in a ``free market.''
This leveraging of power is not `objective' at all. Depending
purely on legal convention, creditors may have debtors impris-
oned, tenants may be evicted without notice and their effects
confiscated, one human being may own another or the land on which
another lives and works, all to varying degrees.
To understand Ayn Rand's psychology it is helpful to know her
background. She was born to a wealthy St. Petersburg family in
1905. The position of her family in Czarist society must have
been considerable. At a time when the lives of most Russians had
changed little since feudalism, her family was wealthy enough to
afford a French Governess and take regular vacations to the Cri-
mea.
It should be noted that wealth in Czarist society was almost
wholly a measure of one's favor with the government. There were
few if any Horatio Alger stories about individuals who lifted
themselves out of serfdom without the patronage of the Czar.
At the age of twelve, she must have been very upset when those
nasty workers took over her father's business. Her family fled
St. Petersburg for the Crimea and the protection of the White
Army.
This experience rendered her forever incapable of seeing land
reform or any struggle of oppressed and exploited people as
anything more than hatred for the good and lust for the unearned.
She shared with Marx the bourgeois ideology that only a few
people were capable of running things. The masses ought to be
happy to have a job working for bosses. Any suggestion that an
enterprise could be run by the employees without having someone
in charge was to her absurd.
She shared with Godwin and Kropotkin the belief that the indi-
vidual is born tabula rasa~a blank slate, and all human knowledge
is derived from sense experience. She then proceeded, however, to
completely dismiss environment and socialization as the determin-
ing factor in the development of character.
People were to her good or evil, brilliant or indolent, depend-
ing solely on their volition. People should be judged by their
actions with equal severity regardless of their condition. Though
she insisted that the United States was not and never had been a
completely free country, she granted no such thing as extenuating
circumstances when judging an individual and had no qualms up-
holding the power of the state to inflict capital punishment.
A far more sinister legacy of Ayn Rand to libertarianism is
that of a moralizing autocrat who gathered about her an inner
circle which she ironically called, ``The collective.''
Outwardly, this collective professed egoism and individuality.
They were to be the vanguard of an intellectual renaissance. The
price of admission to this group, however, was slavish conformity
of one's life and professed philosophy to Ayn Rand's whims and
eccentricities. For example, she did not like men who wore facial
hair or listened to Mozart, and if you didn't give them up you
were unfit for Rand's inner circle.
This is particularly sinister if one considers that Karl Marx,
believed by millions to be the very symbol of liberation, was
also an autocrat who, though professed to be the ultimate champi-
on of democracy, resorted to extraordinary means to maintain
control of the International Workingmen's Association. He even
moved its headquarters to New York to exclude the libertarian
influence.
Today Ayn Rand is gone, but like Marx a century ago, hers is
the primary influence on the largest libertarian organization
existing. Even the pledge which all Libertarian Party members
must sign is taken directly from her admonition, ``I hereby
certify that I do not believe in or advocate the initiation of
force as a means of achieving political or social goals.''
In spite of their pledge to non-violence, many libertarians are
frustrated with election laws and media censorship. An argument
which circulates among libertarians of the right is that, if they
were more threatening, the government may take steps to accommo-
date them as it did the black civil rights movement.
Ayn Rand's writings are not entirely consistent on the point of
non-violence either. In The Fountainhead, Howard Roark resorts to
the use of dynamite. In Atlas Shrugged, Ragnar Danneskjold
engages in piracy on the high seas and even shells a factory
which has been nationalized. In a clandestine rescue mission,
Dagny Taggart shoots a guard who stood in the way of her desired
end.
In the event of economic upheaval, ruined by unemployment and
inflation, tenants and home owners may refuse to make rent and
mortgage payments. The unemployed may seize vacant land and begin
to farm, and factory workers may realize they can run things
without stock holders.
It would not be at all surprising if there were to emerge
within the libertarian right, groups committed to direct action
and counter revolutionary violence, even a coup d'etat.
Imagine a charismatic and autocratic personality at the center
of such a group and you have the Objectivist Lenin.
Like the Marxists and right libertarians, Lenin and the Objec-
tivists are professed republican democrats. Lenin and the Bolshe-
viks promised that if given power, they would immediately convoke
a constituent assembly. When they realized, however, they would
not hold a majority in such an assembly they turned against the
idea of such an assembly.
Can anyone doubt that the cultist mentality which characterizes
most of Miss Rand's followers could lead to the creation of a
group of self appointed avengers of the capitalist class? That
they would suppress strikes, demonstrations, and factory take
overs? That they would not execute people for crimes against the
libertarian state?
Ayn Rand believed in a republican form of government with a
cleverly constructed constitution which would deny the majority
of the power to infringe on the rights of a minority as she
conceived them. If the majority supported a general strike
against rents and mortgages and supported the factory takeovers,
would not the clandestinely organized Objectivist libertarian
party be tempted to dispense with democracy in order to enforce
what they conceived of as the rights of the dispossessed bour-
geoisie?
In all fairness it must be admitted that Ayn Rand herself would
never sanction such actions, but the same argument is made
everyday by western Marxists that Marx would probably not have
sanctioned many of Lenin's actions and would certainly not take
credit for the Soviet Union.
Lenin and the Bolsheviks won power by promising, ``Land to the
peasants!'' ``Factories to the workers!'' When they took power,
however, they immediately set about liquidating the factory com-
mittees and nationalizing the land. They crushed work place
democracy by installing armed guards in the factories, and even
returned former owners to their positions as employees of the
worker's state.
Leon Trotsky stopped the practice of soldiers electing their
officers from their ranks and even restored former Czarist
officers to their ranks in the Red Army.
When the Russian Revolution began few people clearly understood
the gulf which separated the state socialists from the libertari-
ans. Many dedicated libertarians like Alexander Berkman, rallied
to the Bolshevik cause, willing to give them the benefit of the
doubt in hopes that seizing state power would only be a transi-
tional stage toward the development of the stateless/classless
society.
Many sincere lovers of liberty now flock to the standard of the
Libertarian Party, as they did the Bolsheviks, completely igno-
rant of the history of the last century. As Santayanna said:
``Those who forget the mistakes of the past are doomed to repeat
them.''
What should be done? It should be obvious that government
enforcement of private contracts is not libertarian any more than
is taking state power to set people free. Libertarianism is and
always will mean socialism~the self emancipation of working
people.
Libertarians must stop courting the Republican right and return
to their intellectual roots. By standing outside of the political
process we deny the state legitimacy, and like the state tortur-
ers in Atlas Shrugged, they will come and beg for libertarians to
take over.
Remembering the experience of the Spanish libertarians, and
heeding the advice of John Galt, libertarians must refuse state
power even when begged. The state can never be a tool of libera-
tion. Only its complete and utter collapse will allow for the
emergence of non-statist institutions, libertarian coops, com-
munes, and free markets, to flourish and displace the political
state once and for all.
