The Astronomical Almanac is a joint publication of the U. S. Nautical Almanac Office, United States Naval Observatory (USNO), in the United States and Her Majesty's Nautical Almanac Office (HMNAO), United Kingdom Hydrographic Office (UKHO), in the United Kingdom. The printed version contains precise ephemerides of the Sun, Moon, planets, and satellites, data for eclipses and other astronomical phenomena for a given year, and serves as a world-wide standard for such information. The online version extends the printed version by providing data best presented in machine-readable form.
Produced in 1985, this 52-part series helps teachers demystify physics by showing students what it looks like. Field trips to hot-air balloon events, symphony concerts, bicycle shops, and other locales make complex concepts more accessible. Inventive computer graphics illustrate abstract concepts such as time, force, and capacitance, while historical reenactments of the studies of Newton, Leibniz, Maxwell, and others trace the evolution of theories.
Produced by WQED/Pittsburgh in association with the National Academy of Sciences in 1986, this series presents visually spectacular tours of the seven continents as it makes connections between our solar system and Earth’s oceans, climate, and mineral and energy sources. It unifies Earth science, astronomy, and comparative planetology into an integrated discipline that relies on common scientific methods.
