Centenary of liquid helium

On July 10, 1908 Heike Kamerlingh Onnes liquified helium for the first time, and he received the Nobel prize for this work.
The celebration of the centenary of liquid helium will begin in Leiden on July 10, 2008 with the opening of several festivities. The festivities will last for the summer months, or even longer. The LT25 excursion on Sunday, August 10, 2008 will bring you to Leiden so that you can participate in the events.

Conference Excursion  (Note: No more participants can take part in the excursion; it is fully booked)

Naturally, we will go to the place where it all began, the former Kamerlingh Onnes Laboratory, presently called the Kamerlingh Onnes Building. This will be our central meeting point. The building was thoroughly reconstructed after the physics department left this historical place in 1998, and it now houses the Faculty of Law of the Leiden University. Historical photographs will be on display near the location that for several decades was the coldest spot on earth. Most of the original, historical equipment, such as the first liquefier and the ‘big magnet’, has been moved to the Museum Boerhaave. This museum - whose director, Dirk van Delft, wrote the biography of Kamerlingh Onnes - will be organizing a unique exposition “The quest for absolute zero”; it will exclusively be open to the conference participants on our excursion day. There will also be an exposition in the Art Museum “De Lakenhal” with work of Menso and Harm Kamerlingh Onnes, brother and nephew of Heike, respectively. These, and other places to visit, are conveniently located in the center of Leiden, within walking distance of the Kamerlingh Onnes Building.

So you can wander through town and taste the atmosphere of the beautiful city center, visit museums, or the oldest Hortus Botanicus in the world, but you could also stay in the Kamerlingh Onnes Building to listen to various talks about the (scientific) life of Heike Kamerlingh Onnes and his contemporaries Johannes Diderik van de Waals and Hendrik Antoon Lorentz.

Depending on the weather the excursion will be concluded with a reception in the Kamerlingh Onnes Building or in the garden of the historic former University Library, hosted by the City of Leiden, and Leiden University.
