Ross Island sits mid-Willamette just south of downtown Portland, and has a history of being built up and exploited by men, but today it is ruled primarily by nature. From Friendly House, Mike Houck, Director of the Urban Greenspaces Institute, will present his vision of how it can serve as one. Mr. Houck has been a leader in urban nature issues since 1980 when he founded the Urban Naturalist Program at the Audubon Society of Portland. He has co-founded Coalition for a Livable Future (CLF); The national Coalition to Restore Urban Waters (CRUW); The Intertwine Alliance; and The Nature of Cities forum.
Supernovas and Our Fragile Earth
Presentation by Robert McGown. There is a rich history of supernova observations ranging from European to Chinese. Recent supernovas have been discovered by automated telescope search engines. A supernova neutrino blast from a nearby star could extinguish half the life on Earth. This has probably happened during great extinction events of the past. McGown is a self-employed electrician whose interests encompass astronomy and physics. He has a Master’s degree and has co-authored three science books.
