Weather lore, Friday 30 July, 2004
Weather lore, the informal folklore related to the prediction of the weather, suggests that the cumulus humilis clouds in this sky indicate a good day ahead. Such clouds show there is very little convection in the lower atmosphere, and the fact that it is well-formed indicates light winds at low levels. There is no cloud aloft, and thus no moisture or stable conditions or both. The cumulus congestus on the horizon suggests showers may be possible three or four hours from now, at the earliest, but chances are good it will remain a pleasant day through until the evening.

Darlingtonia (Darlingtonia californica), also called the California Pitcher plant or Cobra Lily, is a carnivorous plant in the family Sarraceniaceae.

The genus Darlingtonia is monotypic. Photo credit: Daniel Keshet

Zootomical terms of location, Friday 23 July, 2004
Zootomical terms of location differ from from the terminology used in human anatomy. In animals, the head end is caled the "cranial end" and the tail end is the "caudal end". The side of the body normally oriented upwards is the "dorsal" side; the opposite side, typically the one closest to the ground when walking on all legs, swimming or flying, is the "ventral" side.

Geisha, Thursday 22 July, 2004
Women dressed as geisha in Kyoto, Japan. They are wearing traditional kimonos and geta. Geisha (芸者) are traditional Japanese artist-entertainers. Geisha were very common in the 18th and 19th centuries, and are still in existence today, although their numbers are dwindling. The geisha tradition evolved from the taikomochi or hōkan, similar to court jesters. Geisha were traditionally trained from young childhood although modern geisha begin their training, which remains extremely long and difficult, at much older age. Photo credit: Michael Reeve
Water Buffalo, Wednesday 21 July, 2004
The Water Buffalo is a very large ungulate. It probably survives in the wild in India, Nepal, Bhutan and Thailand; is very widespread as a domestic animal in Asia, South America. North Africa and Europe; and is feral in northern Australia. Wild-living populations of Water Buffalo also exist in much of South-east Asia but their origin is uncertain: they may be the descendants of wild Water Buffalo, formerly domesticated ferals, or a mixture of both. The population of wild Water Buffalo has become very sparse. Photo credit: Chmouel Boudjnah
Planet Mars, Tuesday 20 July, 2004
Mars, the fourth planet from the Sun, is named after the Roman god of war because of its blood red color. Mars has two small, oddly-shaped moons, Phobos and Deimos, named after the sons of the Greek god Ares. At some point in the future Phobos will be broken up by gravitational forces. The atmosphere on Mars is 95% carbon dioxide. In 2003 methane was also discovered in the atmosphere. Since methane is an unstable gas, this indicates that there must be (or have been within the last few hundred years) a source of the gas on the planet. Photo credit: NASA
Bryce Canyon National Park, 19 July, 2004
Bryce Canyon National Park is distinctive due to its unique geological structures, called hoodoos. In winter, most birds in the park migrate, but jays, ravens, nuthatches, eagles, and owls stay. The Mule Deer, Mountain Lion, and coyotes will migrate to lower elevations. Ground squirrels and marmots pass the winter in hibernation. Photo credit: National Park Service

Compound eye of a dragonfly, Saturday 17 July, 2004
A compound eye is a visual organ found in certain arthropods. The compound eye consists of between 12 and 1,000 ommatidia, little dark/bright sensors. The image perceived by the arthropod is "recalculated" from the numerous ommatidia which point in slightly different directions. In contrast to other eye types, there is no central lens or retina. Though the resulting image is poor in resolution, it can detect quick movements and, in some cases, the polarization of light. Dragonflies have about 30,000 facets to their compound eyes, giving them nearly a 360° field of vision. Photo credit: David L. Green
. Sistine Chapel, Friday 16 July, 2004
The Sistine Chapel is a religious chapel and one of the most famous artistic treasures of the Vatican, built between 1475 and 1483, in the time of Pope Sixtus IV della Rovere. The chapel is known worldwide both for being the hall in which conclaves and other official ceremonies are held, including some papal coronations, and for having been decorated by Michelangelo. The subjects of the pictures were historical religious themes. Michelangelo was employed to paint only 12 figures, the Apostles, but when the work was finished there were more than 3,000.

Painter's algorithm, Wednesday 14 July.
The painter's algorithm is one of the simplest solutions to the visibility problem in 3D computer graphics. When projecting a 3D scene onto a 2D plane, it is at some point necessary to decide which polygons are visible and which are hidden. The distant mountains are painted first, followed by the closer meadows; finally, the closest objects in this scene - the trees - are painted. For detailed scenes, the painter's algorthm generally proves to be a slow solution. Photo credit: Fredrik

Moon, Monday 12 July.
The Moon is the only natural satellite of Earth. During the ancient period, it was not uncommon for cultures to believe that the Moon died each night, thus descending into the underworld. As late as the 1920s (or so), it was believed that the Moon might have a breathable atmosphere. In 1969, Neil Armstrong and Buzz Aldrin became the first humans to land on the Moon.
