The 13th podcast on cyclostratigraphy.org is by Mohammad Farhat, a postdoc at IMCCE, Paris Observatory. Mohammad works with Jacques Laskar and the AstroGeo team (http://www.astrogeo.eu/) on refining and extending the orbital and rotational solutions of the Earth into and beyond the Mesozoic. In this podcast, Mohammad discusses the team's recent paper on the tidal evolution of the Earth-Moon system since the formation of the Moon; a classical astronomical tale revived in the midst of the booming cyclostratigraphic machinery.
