Abstract

The Nobel Prize in Physics 2011 has just been awarded to three astronomers: Saul Perlmutter, Brian Schmidt, and Adam Riess, for their amazing discovery of the accelerating expansion of the Universe. Without diminishing the achievement of our community's laureates, here I elaborate on the role of the C&T project in this discovery.
