Are we alone? That question has perplexed humanity for centuries. Perhaps scientists are getting closer to the answer; come find out during four evenings of discussion as biologists, astronomers, chemists and anthropologists talk and share their insights with you as they explain some of their latest research about life on other planets, as well as on our own.
Today, Tuesday, Nov. 29, from 6-7:30 p.m., hear part four of the series, titled "Finding Intelligence."
The search for intelligence in the universe is among the most controversial endeavors in astrobiology. Do we even know what we are looking for? To better understand what "they" might be like, we need to know what is meant by "intelligence." Richard Wrangham, Harvard professor of biological anthropology and author of Catching Fire: How Cooking Made Us Human, is renowned for his lucid explanations of the evolutionary origin of humanity, so he will help us explore what it means for animals to evolve intelligence, and how common this event is in the universe.
Paul Horowitz, Harvard professor of physics and electrical engineering, is the principal investigator in Harvard's SETI (Search for Extra-Terrestrial Intelligence) program and an expert in custom instrumentation. Horowitz joins the final session of the series to talk about what it takes to search for intelligent civilizations in outer space, looking for, or at, human life on planet Earth.
