Purpose
of the Workshop
« La
gastronomie est la connaissance raisonnée de tout ce qui se
rapporte à l'homme en tant qu'il se nourrit»
(Gastronomy is the reasoned knowledge about man's nourishment)
Jean
Anthelme Brillat Savarin (1755-1826)
Writing
about the application of the chemistry to the art of cookery:
« In
what art or science could improvements be made that could more
powerfully contribute to increase the comforts and enjoyments of
mankind »
Sir
Benjamin Thompson, Count Rumford, (1753-1814)
« Molecular
gastronomy is the scientific activity consisting in looking for the
mechanisms of phenomena occurring during dishes preparation and
consumption
Hervé
This and Nicholas Kurti, (1988)
The
above quotations from the writings of two founders of Molecular and
Physical Gastronomy express in a nutshell the spirit and the
objectives of the Workshop: the emphasis will be on gastronomy rather
than nutrition, on domestic and restaurant cooking rather than
industry.
The
object of this workshop will be to bring together a group of
scientists to discuss collectively the science behind the practices
carried out in the kitchen.

What
is a workshop?
The
Oxford English
Dictionary defines a
workshop as “a meeting at which a group of people engage in
intensive discussion and activity on a particular subject or
project”.
Workshops,
similar to seminars, are usually much smaller than conferences – a
workshop can be an element of the conference structure.
Workshops
typically tend to be:
-
Interactive
-
Educational
-
Conversational
May
we also point out that, as the name IWMPG « N. Kurti »
indicates, this is a workshop and that participants are encouraged to
show experiments.
Talks
should never been more than 30 min, so that discussion is promoted
(of course, one can have more slides in order to be ready for the
discussion).
The
primary goal is not to make conferences, but to discuss actively in
all scientific directions: materials and methods, results,
interpretations, consequences, scientific strategy.
Also,
as workshops are more informal than conferences, we could keep the
visio links open during the break and lunches, so that discussions
can go on, and one could discuss other questions than
suspensions during such times.
Mind
that the texts from some talks can be submitted as manuscripts for
the International Journal of Molecular and Physical Gastronomy.
In
memoriam Nicholas Kurti (1908-1998)
Nicholas
Kurti was born in Budapest (Hungary), 14 May 1908, and educated
there in the same Gymnasium as Edward Teller and other famous
scientists... Typical of his early years in Budapest was his
desire to study music. But as a result of anti-Jewish laws, he had
to study in Paris first and then in Berlin. There he worked for a
doctorate under Franz Eugen Simon. The two men became close
collaborators, but -both being Jewish- they prudently decamped
upon the rise of Hitler, finding refuge at the Clarendon
Laboratory in Oxford (1933-1940).
There
they followed their research in magnetism and low temperature
physics, but, at the outbreak of war, they worked on the atomic
bomb project (they were not regarded as sufficiently secure to
participate to radar studies). Back at the Clarendon in 1945,
Nicholas Kurti and Simon used magnetism to obtain the lowest
possible temperatures. They invented the nuclear adiabatic
demagnetization method in 1956.
Nicholas
Kurti did not stand at that point. As he was rising to
professorship of physics in Oxford, to fellowship of Brasenose
College (he was also visiting professor in many universities all
around the world, member or head of more than 20 scientific
committees or organization, where he brought his clear point of
view), he worked on history of science, science policy,
applications of thermodynamics to energy. Obviously he received
many honours appropriate to such a tremendous amount of work and
care: he was member of a dozen academies and he got prizes as the
Holweck Prize (British and French Physical Societies), the Fritz
London Award, the Hughes Medal...
Then,
after the 1970’s, he became interested in what was later called
Molecular Gastronomy
He
never gave explicit advices. Except one : « Let
us have simple experiments ».
« It
is a sad reflection that we know better the temperature inside the
stars than inside a soufflé ».
(Nicholas
Kurti)
