Ça y est : je pars pour le 15e international workshop of molecular and physical gastronomy.

En 1992, avec mon vieil ami Nicholas Kurti, qui avait 50 ans de plus que moi, nous avions décidé de créer le premier la première rencontre de gastronomie moléculaire et physique.
Comme Nicholas connaissait le professeur Antonino Zichichi, directeur du centre de culture scientifique Ettore Majorana, en Sicile, centre qui organisait régulièrement des rencontres de physique fondamentale, nous avions proposé d'organiser le colloque là-bas, et le professeur Zichichi avec accepté à condition que nous puissions démontrer la qualité remarquable des participants. Il ne fut pas déçu, car j'avais invité le physicien Pierre Gilles de Gennes, déjà prix Nobel de physique, qui était venu avec son épouse Anne-Marie, remarquable cuisinière.

C'était là la première rencontre que je dirigeais, et aujourd'hui, 34 ans plus tard, je me vois comme en ce mois de mai 1992, partant pour finaliser les détails de l'organisation et accueillir tous les participants.

Il y a pourtant des différences à commencer par le fait que nous focalisons maintenant bien plus sur la participation scientifique, et si nous avons effectivement réservé une demi-journée pour le monde culinaire, il est bien clair, comme cela l'était d'ailleurs à l'époque, que la gastronomie moléculaire et physique est une discipline scientifique. L'objectif n'a pas changé : il s'agit toujours d'explorer les mécanismes des phénomènes qui surviennent lors des transformations culinaires.

Avec le temps, l'audience s'est élargie et pour les rencontres qui vont se tenir dans les jours prochains à Colmar, nous avons des représentants de 21 pays : des pays où travaillent aujourd'hui des collègues, chimistes, physiciens, biologistes, etc. sur des thèmes de gastronomie moléculaire et physique, que ce soit en recherche ou pour l'enseignement.

Il faut d'ailleurs ajouter que dans les rencontres qui vont avoir lieu, un après-midi entier est consacré à l'enseignement, et notamment à l'enseignement universitaire.

Depuis le début, nous avons insisté sur l'originalité de ces rencontres, qui doivent certes inclure des présentations orales, mais qui doivent donner large part aux discussions et aux expérimentations.

Pour ces dernières, elles auront lieu jeudi matin  : nous les ferons notamment à l'attention des apprentis du CFA hôtellerie restauration de Colmar, qui nous accueille merveilleusement.

Pour les discussions, elles auront lieu sans cesse, du matin au soir, et notamment pendant les pauses et pendant les déjeuners ou les dîners.
 

En 1992, à la fin du workshop, j'avais proposé la création d'une "lettre", sorte de journal moins difficile à gérer qu'un véritable journal
scientifique, mais la proposition, si elle avait été accueillie favorablement, n'avait pas eu beaucoup de succès en termes de soumissions de manuscrits et nous n'avions publié que quelques articles avant d'arrêter la publication. Aujourd'hui, c'est bien différent, car le journal international de gastronomie moléculaire et physique se développe parfaitement, animé par le centre international de gastronomie moléculaire qui est sous la double tutelle de l'Inrae et d'AgroParisTech.

Plus généralement, tout s'est  largement institutionnalisé, tout fonctionne intensément.

Là, il me reste à prendre le train, à rassembler quelques matériels et notamment des coupes pour le crémant d'Alsace qui sera servi avant les déjeuners et les dîners.
Cette remarque peut sembler déplacée,  à propos de rencontre scientifiques, mais depuis la première rencontre, nous avons toujours bu du champagne et mangé des gâteaux. Depuis plusieurs années, et plus précisément depuis que j'organise ces rencontres en région parisienne, le champagne a été remplacé par le crémant mais l'esprit est le même.

Le lieu a changé, lui : après 4 rencontres à Erice, nous en avons eu 10 à Paris, et la prochaine sera donc à Colmar, à la demande des participants qui voyaient le vignoble alsacien sur mon fond d'écran.

Le thème ? Comme chaque fois, il a été décidé par les participants du workshop précédent et nous avons retenu Flavour from food and beverage, le goût des aliments et des boissons.
C'est évidemment un terme très large, mais il permet  à tous de proposer des interventions relatives à des travaux qu'ils font.

 Cette fois, comme les précédentes d'ailleurs, le programme est plein comme un œuf et nous avons même dû refuser certaines présentations orales, privilégiant celles qui étaient le plus dans le thème précis que nous avions choisi.
 
En tout cas, montant dans le train, je me réjouis que des amis se préparent à faire de même, en train, auto, avion,  pour venir nous rejoindre. Il y en aura d'autres qui resteront dans leur pays éloignés et qui suivront la rencontre en visioconférence :  depuis le covid, nous avons appris à organiser des rencontres partiellement physiques, partiellement électroniques.
Nos amis éloignés n'auront ni crémant ni Kougelhopf, mais nous aurons le plaisir de discuter avec eux de ce sujet passionnant qu'elle a gastronomie moléculaire et physique.

If you want to attend the next International Workshop on Molecular and Physical Gastronomy, it's not too late.

I receive questions about the next workshop on molecular and physical gastronomy : 
 
Dear Mr This,
I send you this email because I would like to know if it is possible to attend to a part of the next International Workshop on Molecular and Physical Gastronomy" (depending on my agenga). 
I am very interested by the questions which are going to be adressed. However it seems that the participants are confirmed scientists. Can I anyway apply, as someone very interested by this topic? 
Sorry for this late application.
 
And here is the answer : 
 
The "workshop" is like a friendly seminar of a lab, which means that anyone is welcome, in order to show scientific results, or to hear about the results shown by some. 
All the discussions are in  English, and there are colleagues of any age, country, profession... For example, the younger colleagues of the lab (https://hervethis.blogspot.com/2019/01/les-collegues-plus-jeunes.html) will attend. 
It is very friendly, and anyone comes when he/she can come. 
No problem for attending, but we need an application including  :


Family name, First name (Pr/Dr/Mr/Ms)
Affiliation (job)
Post adress
Phone :
Email
 
The workshop will take place Room 31, at AgroParisTech, centre Claude Bernard : 
16 rue Claude Bernard, 75005 Paris, France. 
 
The programme is the following :

9 th Meeting (IWMG 09)


Organized by the AgroParisTech-INRA International Centre for Molecular Gastronomy




Flavour through cooking


Director: Hervé This
Organization Committee:
Pr Roisin Burke (Dublin Institute of Technology, Dublin, Ireland), Pr Hervé This (AgroParisTech-Inra), Pr Dan Vodnar (University of Cluj-Napoca, Romania)








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 culinary science express in a nutshell the spirit and the objectives of the Workshop: the emphasis will be on gastronomy (i.e. knowledge) 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 was called “molecular and physical gastronomy” in 1988.
Previous workshops have been held on the role of emulsions, the effects of cooking methods on food quality and the management of food flavours. The 9th IWMG will focus on “Flavour through cooking”.
May we also point out that, as the name IWMG indicates, this is a workshop and that participants are encouraged to make use of the laboratory (near the lecture room) which is reasonably well provided with both culinary and scientific equipment.


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 Hervé This and himself called Molecular Gastronomy (1988).


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)

S'inscrire au 9e International Workshop on Molecular and Physical Gastronomy ?

On m'interroge à propos de notre prochain atelier de gastronomie moléculaire : 
Cher monsieur This,
Je me permets de vous adresser ce courriel afin de vous demander s'il serait possible d'assister à une partie des sessions de "l'International Workshop on Molecular and Physical Gastronomy" (en fonction de mes occupations pendant la semaine). 
Je suis en effet très intéressé par les questions soulevées. 
Cependant, il m'a semblé que le public concerné est essentiellement celui de scientifiques confirmés. Puis-je malgré tout envisager de m'inscrire en tant que passionné ? 

Veuillez également m'excuser pour cette demande un peu tardive.
Et voici ma réponse : 
Le "workshop" est  comme un séminaire de laboratoire, à savoir que chacun peut venir y présenter des résultats scientifiques ou pédagogiques. 
C'est en anglais, et il y a des collègues de tous âges. Par exemples, les "collègues plus jeunes"  (https://hervethis.blogspot.com/2019/01/les-collegues-plus-jeunes.html) de mon laboratoire y assisteront.
C'est très amical, et chacun vient quand il peut.
Donc pas de pb pour vous inscrire, mais il me faut des coordonnées comme : 

Nom, Prénom (Pr/Dr/Mr/Ms)
Affiliation (état)
Adresse postale
Téléphone :

A noter que le workshop se tiendra avec le programme suivant en salle 31 d'AgroParisTech, centre Claude Bernard, à l'adresse : 
16 rue Claude Bernard, 75005 Paris, France. 
Bonne journée
