Dr. Friedemann Freund - February 16 2008

Our February speaker will be Dr. Friedemann Freund. He is a professor at San Jose State University and also works at SETI. In 2005 in an issue of SETI’s Explorer magazine it said the following: “Traditionally, scientists have argued that oxygen became prevalent largely as the byproduct of photosynthesis. But Freund and microbiologist Lynn Rothschild of NASA suggest the mechanism may be much simpler: the weathering of rocks ... If their hypothesis is correct, we might expect oxygen to be prevalent in the atmospheres of many Earth-like planets.” Dr. Freund has also worked on earthquake predictions. In April of 2006 he spoke before the Commonwealth Club about the pre-earthquake signals that the Earth sends to us.
