World Sunlight Map

World Sunlight Map
Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and darkness. The clouds are updated daily with current weather satellite imagery. The Mercator projection used here is one way of looking at the spherical earth as a flat map. Used since the 16th century for navigation, straight lines on this map can be used accurately as compass bearings but the size and shape of continents are distorted. Compare this with Peters, Mollweide or equirectangular projection maps. Also available is a semi-realistic view of dawn and dusk from far above the Earth, a look at the moon, and information about how this works.

Solar System, Solar System Information Our Cosmic Neighborhood From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars.

Recapitulation The embryonic development of all vertebrates shows remarkable similarities as you can see from these drawings (supplied by Open Court Publishing Company). The drawings in the top row are of the embryonic stage called the pharyngula. At this stage ("I") they all contain a: notochorddorsal hollow nerve cord a tail extending behind the anus a series of paired branchial grooves.

Daqri's 4D Cubes Use Augmented Reality To Teach Kids The Periodic Table Of Elements The worst part of high school? Most kids might say having to read The Scarlet Letter, or puberty. (I enjoyed both, thank you very much.) But arguably the most boring aspect was memorizing the periodic table--and all its damn elements, symbols, and atomic numbers. Now one Los Angeles company plans to spice up the periodic table, Hollywood-style.

Lunar Cycle Thousands of years of observation have shown that lunar rhythms affect us all, collectively and personally, instinctually and unconsciously. From the earliest simple etchings of moon phases on sticks, humanity has found ways to identify measure and predict the timing of events based on the cycles of the Sun, Moon, and Earth. Modern calendars, the tools we use for synchronizing our activities with the rest of the world, continue to be calculated using a soli-lunar formula. Although lunar phases are known to dictate the movement of tides; the growth of plants; and the breeding habits of domesticated animals, fish, and game; we have become so out of touch with nature that few of us even notice the moon unless it’s dramatically full. 10 Incredible Photos of Animals In The Womb Animals The chance to see things from a different perspective ranks among humanity’s great needs. The following images of animals in the womb offer a totally new way of seeing other species on this planet; they cause us to pause, and—at least for a short time—to reflect on everything that is incredible about existence. This photo shows a bottlenose dolphin about six months through its gestation period.
