Pierre Larroque was trained in sciences in France and has always kept a keen interest in the history of scientific thought.

From the origins, women and men have looked at the night sky and wondered about it all. They observed the moon phases and the appearance of constellations at regular places and times in the night’s horizon (the Zodiac). The Greeks specifically recorded the consistent retrograde movements of five wanderers (“planets” in Greek) amongst all stars, which they strove to explain in an orderly earth-centered Universe.  It is only early in the 17th century that Kepler described the solar system correctly, and late in that century that Newton published the laws which underpin not only the planets’ movements but all classical gravitational phenomena.  It took Einstein at the beginning of the 20th century satisfactorily to synthesize and justify the laws of gravity, and numerous followers later in that century to establish quantum mechanics as the theory which explains what the basic constituents of the Universe are and how they behave. 

Pierre Larroque will lead you through this extraordinary journey of discoveries, culminating with how certain we are of how the Universe was created in a Big Bang 13.79 billion years ago, and why it is today as we live it.
