Subject: [evol-psych] Claude Shannon, Father of Information Theory, Dies at 84
Murray Hill, N.J. (Feb. 26, 2001) -- Claude Elwood Shannon, the mathematician
who laid the foundation of modern information theory while working at Bell Labs
in the 1940s, died on Saturday. He was 84.
Shannon's theories are as relevant today as they were when he first formulated
them. "It was truly visionary thinking," said Arun Netravali, president of
Lucent Technologies' Bell Labs. "As if assuming that inexpensive, high-speed
processing would come to pass, Shannon figured out the upper limits on
communication rates. First in telephone channels, then in optical
communications, and now in wireless, Shannon has had the utmost value in
defining the engineering limits we face."
In 1948 Shannon published his landmark A Mathematical Theory of Communication.
He begins this pioneering paper on information theory by observing that "the
fundamental problem of communication is that of reproducing at one point either
exactly or approximately a message selected at another point." He then proceeds
to so thoroughly establish the foundations of information theory that his
framework and terminology remain standard.
Shannon's theory was an immediate success with communications engineers and
stimulated the technology which led to today's Information Age.
Shannon published many more provocative and influential articles in a variety
of disciplines. His master's thesis, A Symbolic Analysis of Relay and Switching
Circuits, used Boolean algebra to establish the theoretical underpinnings of
digital circuits. This work has broad significance because digital circuits are
fundamental to the operation of modern computers and telecommunications
systems.
Another example is Shannon's 1949 paper entitled Communication Theory of
Secrecy Systems. This work is now generally credited with transforming
cryptography from an art to a science.
Shannon was born in Petoskey, Michigan, on April 30, 1916. He graduated from th
e University of Michigan in 1936 with bachelor's degrees in mathematics and
electrical engineering. In 1940 he earned both a master's degree in electrical
engineering and a Ph.D. in mathematics from the Massachusetts Institute of
Technology (MIT).
Shannon joined the mathematics department at Bell Labs in 1941 and remained
affiliated with the Labs until 1972. He became a visiting professor at MIT in
1956, a permanent member of the faculty in 1958, and a professor emeritus in
1978.
Shannon was renowned for his eclectic interests and capabilities. A favorite
story describes him juggling while riding a unicycle down the halls of Bell
Labs.
He designed and built chess-playing, maze-solving, juggling and mind-reading
machines. These activities bear out Shannon's claim that he was more motivated
by curiosity than usefulness.
In his words "I just wondered how things were put together."

Condorcet: Communication/Science/Democracy
Condorcet is usually regarded as the last footnote to the history of
French Enlightenment.The
paper - an attempt at his "rehabilitation" - tries to disclose the
conceptual
connectionsbetween his philosophy of history, his views of science as
simultaneously an
epistemic andsocial formation, and his political philosophy. His ideas
not only prefigure some
more contemporary theories - his dispute with Rousseau represents the
first great
confrontationbetween the two great cultural trends of modernity, between
(the broadly
understood)"Enlightenment" and "Romanticism".

Chaos, Irreversibility and Indeterminism
There is a debate going on concerning the nature of science of today
that centres round
theproblems of chaos, irreversibility and indeterminism. The debate has
been provoked by
theworks of Ilya Prigogine, who advocates a principal turn in science
during the last
decadesof XX-th century. The claims of Ilya Prigogine have been
criticised by Jean Bricmont,
whorefuses to recognise the novelty of the approach of I. Prigogine. It
seems, however, that
J.Bricmont has not hit the target with his criticism. Putting it
somewhat roughly, the main
reason of I. Bricmont's misfire seems to be his concentration on the
problem of
determinism,whereas the heart of the matter lies in irreversibility.
Therefore, the aim of the talk
is clarifyingthe issues of indeterminism and irreversibility in the
light of the debate mentioned
above. It isuseful to fulfil this purpose by addressing the nature of
the different types of
chaos,deterministic and quantum. Although the main source of the
discussion is
contemporary, Ineed to take a short look back at the ideas of Ludwig
Boltzmann, whose works
have clearlyinspired both of the debating parties.

Dekoherencia es disszipacio a kvantumkomputer
egy lehetseges modelljeben
Az altalunk vizsgalt problema ketnivosnak tekintheto atomok viselkedese
az atmenettel rezonans mikrohullamu uregben. Az elmult nehany evben
szamos latvanyos kiserletet vegeztek abban az esetben, amikor az uregben
egyszerre csak egyetlen atom tartozkodik. Megfeleloen preparalt
atomokkal letrehoztak a mezo olyan allapotait, amelyek Schrodinger
macskajanak modelljekent tekinthetok, azaz ket makroszkopikusan
megkulonboztetheto mezo-kvantumallapot szuperpoziciojat valositottak
meg, majd ellenoriztek, hogy milyen gyorsan tunik el ezek kozott az
interferencia, attol fuggoen, hogy mennyire engedik az - egyebkent
lehetoseg szerint zart - rendszert kolcsonhatni a kornyezettel.
Egy ilyen kiserlet inverze lenne az, ahol a mezo ket klasszikus
allapotanak nemklasszikus szuperpozicioja helyett sok atom nemklasszikus
szuperpoziciojanak viselkedeset vizsgaljuk. Egy lehetseges
kvantumkomputerben ezek az atomok valositanak meg a qubiteket, es a
szupravezeto ureg, ha eleg jo, csak kevesse engedne oket kolcsonhatni a
kulvilaggal. Ezt a rendszert ugy kellene kontroll alatt tartani, hogy az
atomok egymashoz kepest is tartsak a fazisukat vagyis maradjanak
lehetoleg minel hosszabb ideig kvantumos szuperpozicioban. Sajnos
azonban minel tobb atom van, ez annal nehezebb. Megmutatjuk, hogy egy
ilyen kiserletnel a dekoherenciat es a disszipaciot ugyanazon modell
kereteben lehet leirni. Megmutatjuk tovabba, hogy az altalaban nagyon
gyors dekoherencia mellett megis leteznek olyan makroszkopikus
szuperpoziciok, amelyek viszonylag hosszan megtartjak a koherens
viselkedest.

CONSCIOUSNESS AND ITS PLACE IN NATURE
Toward a Science of Consciousness: Sweden 2001
Skövde, Sweden, August 7-11, 2001
What is the place of consciousness in nature? Despite many advances in
science, this question remains unanswered. Some hold that consciousness
does not exist; some hold that it is reducible to processes in the brain;
some hold that it is an irreducible nonphysical entity; some hold that it is
tightly connected to fundamental physics; and some hold that we will never
understand it at all.
This conference will address the place of consciousness in nature from a
wide variety of perspectives. It will bring together philosophers,
neuroscientists, cognitive scientists, physicists, and others, to present
theoretical and experimental research that bears on the the place of
consciousness in the natural order. Issues that will be addressed include:
o Is consciousness a physical process?
o What are the neural correlates of consciousness?
o How can we build a systematic theory of consciousness?
o Is consciousness connected to fundamental physics?
o What is the relationship between the subjective and the objective?
o To what degree are animals conscious?
o Can machines be conscious?
o How does consciousness fit into the social and cultural order?
o Are naturalistic accounts of consciousness circular, given that
experience of nature is a construct of the mind?
PAPER AND POSTER SUBMISSIONS MUST BE RECEIVED BY MARCH 26, 2001.

Final Announcement
UNIVERSITY OF OXFORD
OXFORD SUMMER SCHOOL ON CONNECTIONIST MODELLING
Department of Experimental Psychology
University of Oxford
Sunday July 15th to Friday July 27th, 2001
Applications are invited for participation in a 2-week residential
Summer School on techniques in connectionist modelling. The course is
aimed primarily at researchers who wish to exploit neural network
models in their teaching and/or research and it will provide a general
introduction to connectionist modelling, biologically plausible neural
networks and brain function through lectures and exercises on
Macintosh's and PC's. The course is interdisciplinary in content
though many of the illustrative examples are taken from cognitive and
developmental psychology, and cognitive neuroscience. The instructors
with primary responsibility for teaching the course are Kim Plunkett
and Edmund Rolls.
No prior knowledge of computational modelling will be required though
simple word processing skills will be assumed. Participants will be
encouraged to start work on their own modelling projects during the
Summer School.
The cost of participation in the Summer School is stlg950. This figure
covers the cost of accommodation (bed and breakfast at St. John's
College), registration and all literature required for the Summer
School. Participants will be expected to cover their own travel and
meal costs. A number of partial bursaries will be available for
graduate students. Applicants should indicate whether they wish to be
considered for a graduate student scholarship but are advised to seek
further funding as well, since in previous years the number of
graduate student applications has far exceeded the number of
scholarships available.
There is a Summer School World Wide Web page describing the contents
of the 2001 Summer School available on:
http://www-cogsci.psych.ox.ac.uk/summer-school/
If you are interested in participating in the Summer School, please
send a brief description of your background with an explanation of why
you would like to attend the Summer School (one page maximum) no later
than 28th February 2001 to:
