Free online lectures: Explore a world of ideas

Funding provided by:

Museum of Science, Boston

One of the world's largest science centers, the Museum of Science, Boston attracts 1.6 million visitors a year through vibrant programs and over 550 interactive exhibits. Its mission is to stimulate interest in and further understanding of science and technology and their importance for individuals and society. Other features include the Thomson Theater of Electricity; Current Science & Technology Center; Charles Hayden Planetarium; Gilliland Observatory; and Mugar Omni Theater. The Museum's exhibit plan, Science Is an Activity, has been awarded several National Science Foundation grants and profoundly influenced exhibit development at other major science centers.

Planets and the Search for New Earths

Wed, Oct 16, 2002

Wesley Traub describes how scientists have succeeded in their quest to find new planets, what they have seen so far, and how they will look for life on these new worlds. Less than a decade ago, the only planets known to exist were the nine of our solar system. Now astronomers have found more than 100 worlds around other Milky Way stars. Most are Jupiter-sized, but Earth-sized orbs may be hiding nearby.

Our Special Planet: A Cradle for Life

Wed, Oct 23, 2002

Peter D. Ward describes the unique traits of our solar system that helped life to gain an initial foothold. Once life arises, it survives tenaciously. Ward explains how important is it to have a Jupiter to divert threatening swarms of comets, a large moon to provide nurturing tides, and a crust of moving plates to recycle the stuff of our world. Despite the flood of newly discovered worlds, Ward argues that our planet is more precious than we may realize.

Next Generation Communication Technologies

Wed, Jan 14, 2004

This discussion looks at the current and potential uses of communications technologies and what the implications may be for today and tomorrow. From the invention of the telegraph in 1837 to modern day digital cell phones and GPS navigation systems, communication technologies have come a long way in a short time. Communication devices now serve a broad range of uses, from controlling satellites more than a billion miles from Earth to communicating with tiny networks of devices inside the human body.

Hydrogen Based Economy: Just A Dream?

Wed, Jan 28, 2004

This panel presentation reviews the current status of reasons and technologies for hydrogen production in our quest for economical, reliable, environmentally sound energy. It also provides an introduction to proton-exchange membrane (PEM) fuel cells, how they function, and a discussion of the technological challenges overcome in recent years and those that still exist in developing and commercializing fuel cells. Panelists are from the Worcester Polytechnic Institute, and include professors Yi H. (Ed) Ma and Ravindra Datta, James P. Dunn, President of Tech Commercialization, and William Durgin, Vice President of Research. As we celebrate the 100th anniversary of the Wright Brother's flight, we look toward the future of aviation technology - fuel cell powered electric aircraft. At just 346 pounds, the all carbon DynAero Lafayette III soon will take a critical step toward becoming the first piloted plane to be powered by fuel cells.

Nanotechnology: The Next Small Thing?

Wed, Jan 21, 2004

Nancy A. Burnham, W. Grant McGimpsey, and William Durgin discuss consumer products that take advantage of the possibilities of nanotechnology, and what we can expect to see on the market in the near future. The computer industry is continually working to make transistors smaller, cheaper, and faster. As systems become tinier, they behave in ways that are fundamentally different from those made on a macroscopic scale. Because of this great difference, nanotechnology presents new opportunities and possibilities.

Improbable Research and the IgNobel Prizes

Fri, Apr 1, 2005

Join the IgNobel Prizes founder and host Marc Abrahams for a look at some of the most mind-popping IgNobel Prize winners. The IgNobel Prizes, awarded annually at a ceremony at Harvard University, honor things that first make people laugh, and then make them think. The awards are designed to celebrate the unusual, honor the imaginative, and spur people's interest in science, medicine and technology.

Unicorn in Captivity: Science Helping Art

Wed, Jan 18, 2006

Brothers David and Gregory Chudnovsky discuss their contribution to the Metropolitan Museum of Art's Unicorn Tapestries project. To create an exact visual reproduction of one of the Metropolitan Museum of Art's Unicorn Tapestries, digital cameras photographed every inch. When the hundreds of digital photographic files didn't fit smoothly together, the Chudnovsky brothers, co-directors of the Institute for Mathematics and Advanced Supercomputing, were brought in to solve the mystery. Art and science have continually flirted over the centuries. Both investigate. Both involve theories and transforming information into something else. This lecture is a part of a Museum of Science series "When Science Meets Art", which examines the mysterious symbiosis of science with art through the ingenuity of those shattering the boundaries between the two fields.
