Feature 1 – Tesla (start time 5:30) Nicola Tesla is one of the iconic figures of the early electrical age. He invented AC motor technology still used today in your DVD player and also polyphase AC power. He was a brilliant demonstrator, whose images of flowers of lightning growing from his inventions and portraits of his friend Mark Twain, illuminated by Tesla’s fluorescent bulbs, are still familiar today. He worked with and fought with the mighty JP Morgan and wireless radio great Marconi. He is a figure of mystery, who many believe presaged death rays and infinite and free energy for everyone on earth. Biographer Bernie Carlson has written the book “Tesla: Inventor of the Electrical Age.” We talk with Bernie about Nicola Tesla’s mental method of invention, Colorado experiments, and modern mystique.
Feature 2 – Octopus! (start time 14:35) If you doubt that the Octopus may be the most mysterious creature in the sea – consider this – an octopus has three hearts, eight arms, camouflaging skin, and some of them can figure out ways to do things that many humans can’t – such as getting the lid off of a child-proof bottle. Longmont resident Katherine Harmon Courage is with us today to discuss her new book, “Octopus! The Most Mysterious Creature In the Sea.”

Feature 1 – Flood Winners & Losers : Last month’s deluge cut canyons, real and felt, through many of our lives, but nature helps us remember that floods can build too. In this feature, How on Earth’s Jim Pullen speaks with Boulder’s wetland and riparian ecologist Marianne Giolitto about flood “winners and losers”. Marianne watches over 45,000 acres of the city’s open space and mountain parks wetlands and riparian habitats. Jim and the Boulder Open Space and Mountain Parks are working together on a

humans for millenia. Aristotle argued comets were hot, dry exhalations gathered in the atmosphere and occasionally burst into flame. Some people thought that comets replenished Earth’s air. Still others believed they were a source of disease. Scientists today study comets because some are thought to be relatively pristine leftover debris from the formation of the solar system. And studying what comets are made of can provide us a glimpse back to the beginning of the solar system 4 billion years ago.

Good & Bad Calories (starts at 4:50) Ever since the 1970s, the rise of obesity in the United States has an epidemic. Researchers around the world are trying desperately to figure out why so many of us get fat, and what we can do to change that. A large amount of funding, and support from public health policy, goes toward the hypothesis that we get fat because we eat too many calories and do not exercise enough; when someone eats more calories than they need, the instructions go, they should exercise. That’s “Calories in, Calories Out.” But recently, an expert with a different point of view spoke to a packed audience of doctors, staff and medical students at the University of Colorado Medical Center. The expert is
