Congratulations to beautiful and sensual Rio de Janeiro! In August the city hosted the International Astronomical Union General Assembly, an event that only happens every 3 years. Maybe some of you saw my talks on the Moon and the changing speed of light. Today Cariocas can look forward to another special event, as hosts of the 2016 Olympics! Despite last-minute pleading and pandering by Chicago's president, Rio won the honour hands-down. Sports fans can look forward to beautiful beaches, tanned bodies and lots of parties!Readers of this blog have travelled from atop the John Hancock Center in Chicago to the beaches of Rio. The best is yet to come!
