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.

Double Helix: Genomes to Biological Networks

Wed, Mar 5, 2003

This is the fourth in a four-part series of lectures celebrating the 50th anniversary of Watson and Crick's discovery of DNA in 1953. These lectures explore the impact this breakthrough is having on scientific discovery today. Part IV: The human genome project has provided researchers with a growing list of genes; but the key to understanding life, both in health and sickness, is the script that outlines how these cellular players interact with each other. Ideker discusses how researchers are using new approaches to biology to map out cell circuitry and illuminate the cause of disease.

Out of Hibernation: Exposing the Secret Lives of Bears

Mon, Mar 1, 2004

John Foster introduces us to black bears, the often misunderstood bear species that is making a population comeback all over New England. Foster, the founder of the New England Naturalist Training Center, has spent a lifetime with these furry creatures, and shares his insight and photographs.

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.

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.

Transit of Venus: Passing the Sun

Wed, Apr 7, 2004

David A. Aguilar and Jay M. Pasachoff discuss June 8th, 2004, when we on Earth will witness Venus passing in front of the Sun for the first time in 122 years. This phenomenon, known as the transit of Venus, is one of the rarest of planetary alignments. The transit lasts about 6 hours and is visible from most of Europe, Africa, and Asia though, similar to an eclipse, it cannot be witnessed without a sun filter. Observations of the transit were used in the 18th and 19th centuries to determine the size of the solar system. That method has since been dismissed for its impracticality, but the transit will provide much opportunity to develop and test new techniques for the study of planets outside our solar system.

Exploring Saturn and Its Titan Moon

Wed, Apr 14, 2004

David A. Aguilar and Carolyn C. Porco explain that, while aspects of Saturn are still mysteries, scientists hope that the Cassini-Huyguns Space Craft (due to approach Saturn's orbit in July of 2004) will answer many questions. Saturn, the second largest planet in our solar system, is a gaseous giant encircled by 31 moons and, of course, its brilliant rings. The Cassini Orbitor will circle the planet and its moons, while the Huyguns Probe will land on the surface of Titan, Saturn's largest moon.
