Size and scale can be difficult concepts to teach. TI staff educator Lori Lambertson talks us through one of her favorite activities, using one of her favorite dolls-Barbie. It can be hard to make ideas about size and scale relevant to students’ lives. Children’s book author David Schwartz explains a series of neat real-world comparisons from his book that really get the concepts across.
Julia Moore and Evan Michelson of the Woodrow Wilson International Center for Scholars talk about nanotechnology products they’ve found for sale in a variety of stores. Should these products have some sort of special label? Journalist Philip Ball also weighs in on the controversy. Dr. Jim Tour, a chemist at Rice University, builds the world’s smallest vehicles. He calls them “nanocars,” and he thinks these tiny vehicles might lead to nano-sized factories. We’ll also hear from University of Florida graduate student Diane Hickey, who will tell us some of the interesting reactions she’s run into when explaining nanotechnology. Join us as we speak with IBM Fellow Dr. Don Eigler, who first used a scanning tunneling microscope to demonstrate the ability to build structures at the atomic level by spelling “I-B-M” with individual atoms. Also, meet Tom Rockwell, Director of Public Exhibition at the Exploratorium, who describes, in an audio essay, how he imagines the land of the very small. Paul Doherty and Ron Hipschman discuss some of Saturn's interesting history. Join the Origins team as they travel to Antarctica. We sent Mary, Noel, Paul, and Julie to explore scientific wonders from McMurdo to the Pole. Learn all about the extreme science being conducted at the South Pole in a daily dispatch from Terra Australis Incognita! In 1963 Benoit Mandelbrot introduced the fractal concept. Fractals are shapes or behaviors that have similar properties at all levels of magnification. Just as the sphere is a concept that unites raindrops, basketballs and Mars, so fractal is a concept that unites clouds, coastlines, plants and strange attractors.
Dr. Mandelbrot dropped in for a visit during our 2001 series of webcasts about Antarctica. We took some time out from the freezing cold to interview him.
Dr. Paul Doherty scours the globe for the world's greatest science demonstrations. Here he partners with Dr. Yoji Takikawa of the International Christian School in Tokyo. Dr. Takikawa creates at least one new activity every month and has published over 25 books of science activities. Watch this webcast, follow the links to the 'recipes,' then try it yourself!
