Speculate on the possibility that cosmic snowballs created Earth's water supply as you view photos of icy comets striking Earth's atmosphere and breaking up into water vapor. Prepared by the American Institute of Physics to encourage physicists to contact their congressmen to support funding for physics research, Physics Success Stories highlights the important links between federal funding for basic and applied research and development and their economic benefits to society. This excellent site graphically illustrates how physics research and development saves us money, improves health, protects people through our national defense, drives progress in transportation, fills our home with consumer goods, connects the world through telecommunications, stimulates industry with laser technology, creates jobs in the computer industry, saves lives with medical imaging, designs the future by developing new materials, launches new business with a Global Positioning System, and helps imporve our air quality. It contains images and information about the Sun, planets, moons, asteroids, comets and meteoroids found within the solar system. It contains over 220 pages of information, over 950 high-resolution images and animations, and over 880 megabytes of data.
