Christmas Lecture 2016

Bekijk hier de sfeerbeelden van 2016 en de presentatie van 2016!

The Christmas lecture 2016 was again an overall success. The alumni society Science@Leuven invited Étienne Ghys, mathematician and director of CNRS (Centre National de la Recherche Scientifique, France) and ENS (École Normale Supérieure) of Lyon, who challenged his audience by questioning the shape of the Earth. We all know that the Earth is round but is this the only mathematical solution? Ghys does not bore his audience with complicated formulae but shows instructive and interactive videos, developed by the Antwerp engineer Jos Leys, to explain mathematics that is more difficult to grasp. The alumni society Science@Leuven also had to say goodbye to their chairman Jos Peeters, who after 8 years of combining innovation, research and entrepreneurship passes the baton to Steven Dessein, director of the Botanic Gardens of Meise. Jos Peeters surprised the Faculty of Science by donating a main scholarship in name of Jos and Christine, his beloved wife, for exceptional foreign students, which the faculty gratefully accepted. To wrap up the Christmas lecture 2016, the dean presented the programme of the upcoming anniversary year in 2017 when the Faculty of Science celebrates its 200th birthday. With the baseline “advanced curiosity”, the Faculty of Science is devoted to keep on providing high quality and innovative education, research and social services. Afterwards the invited guests, personnel, alumni and students could catch up with a nice nibble and a drink during the traditional Christmas reception.

Uitnodiging

 

Prof. dr. Peter Lievens, decaan van de Faculteit Wetenschappen, en
dr. Jos B. Peeters, voorzitter van de alumnivereniging Science@Leuven,
nodigden u van harte uit op de jaarlijkse Christmas Lecture

 


The shape of the planet Earth?
An unexpectedly deep mathematical challenge!

 

Prof. dr. Étienne Ghys

Unité de Mathématiques Pures et Appliquées

École Normale Supérieure de Lyon

Lyon, France

op zaterdag 10 december 2016 om 15.00 uur
in auditorium Pieter de Somer
de Bériotstraat 24, Leuven

 

According to some legend, Galileo said: « Eppur si move ! » after his trial in 1633. He was right: our planet Earth is rotating!
The centrifugal force produces some equatorial bulge so that the Earth is not exactly spherical. Newton was the first to get
an estimate of the flattening of the Earth by a purely theoretical reasoning, « without having to get out of his home »,
as Voltaire wrote. This lecture will not discuss geophysics. On the contrary, I would like to focus on the purely mathematical
theory raised by this problem, which was at the origin of the crucial scientific concept of « bifurcation ». I will discuss historical
developments, like for instance the surprising discovery by Poincaré of rotating bodies having the shape of a pear! This discovery
is purely theoretical since nobody has ever witnessed such an object rotating in space. A wonderful example of the interaction
between pure and applied science.
