IHP, the Henri Poincaré Institute

Located in the heart of the 5th arron-dissement of Paris, the Henri Poincaré Institute is one of the oldest and most dynamic international structures dedi-cated to mathematics and theoretical physics. Close to the Pantheon and the Jardin du Luxembourg, the IHP bene-fits from beautiful surroundings. The House of Mathematics and Theo-retical Physics ˝ offers an ideal place to study in the heart of the Latin Quarter.

Conference DinnerThursday, September 8th at 8:00 pm

The Restaurant du Musée d’Orsay˝The history of the museum and of its building is quite unusual. In the centre of Paris on the banks of the Seine, opposite the Tuileries Gardens, the museum was installed in the former Orsay railway station, built for the Universal Exhibition of 1900. Thus, the building itself could be seen as the first work of art˝ in the Musée d’Orsay, which displays collections of art from the period from 1848 to 1914.The former restaurant of the Hôtel d’Orsay, on the first floor of the museum, is still as magnificent as it was when it opened in 1900. The new furniture sets off the dazzling chandeliers and the painted and gilded ceilings of this dining room, listed as a Historic Monument. The chef Yann Landureau offers traditional French cuisine, interspersed with original dishes that are linked to the museum’s current events. The museum itself is open late on Thursdays, and you will be able to visit its collections just before the dinner (starting at 6 pm).
