Solar Eclipse Of December 4, 2002
A total solar eclipse occurred at the Moon's descending node of orbit on Wednesday, December 4, 2002, with a magnitude of 1.0244. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring about 1.9 days after perigee (on December 2, 2002, at 8:50 UTC), the Moon's apparent diameter was larger. The eclipse was visible from a narrow corridor in parts of Angola, Botswana, Zimbabwe, South Africa, Mozambique, the Indian Ocean and South Australia. A partial eclipse was seen from the much broader path of the Moon's penumbra, including most of Africa and Australia in addition to parts of Indones ...

IMac
The iMac is a series of all-in-one computers from Apple Inc., sold as part of the company's Mac (computer), Mac family of computers. First introduced in 1998, it has remained a primary part of Apple's consumer desktop offerings since and evolved through seven distinct forms. The iMac natively runs the macOS operating system. In its original form, the iMac G3 had a gumdrop, ADM-3A#ADM-3, ADM-3 or Oval#Egg shape, egg-shaped look, with a Cathode ray tube, CRT monitor, mainly enclosed by a colored, Transparency and translucency, translucent plastic case. The computer was, at the time, an inexpensive, consumer-oriented computer that would easily connect to the Internet. The second major revision, the iMac G4, moved a design with a hemispherical base containing all the main components and an Liquid crystal display, LCD monitor on a freely moving arm attached to it. The third and fourth revisions, the iMac G5 and the iMac (Intel-based), Intel iMac, placed all the components immediate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple, Inc
Apple Inc. is an American multinational corporation and technology company headquartered in Cupertino, California, in Silicon Valley. It is best known for its consumer electronics, software, and services.

IMac G4
The iMac G4 is an all-in-one personal computer designed, manufactured, and sold by Apple Computer from January 2002 to August 2004. The computer is comprised of a hemispheric base that holds the components, including a PowerPC G4 processor, and a flatscreen liquid-crystal display (LCD) mounted above. The display is connected to the base via an adjustable arm that allows the monitor to be tilted and swiveled. Apple's previous release, the iMac G3 (1998), was a commercial success at a time when the company was close to bankruptcy. As component prices fell, Apple envisioned a replacement that would use an LCD instead of the G3's bulky cathode-ray tube. The resulting iMac G4 took two years to develop. The new shape was inspired by a sunflower, with Apple's design team exploring different ways of attaching the monitor to the base before settling on a single stainless steel arm. The iMac G4 eschewed the colorful translucency of the iMac G3 in favor of opaque white with silvery acce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hobo–Dyer Projection
The Hobo–Dyer map projection is a normal cylindrical equal-area projection, with standard parallels (there is no north-south or east-west distortion) at 37.5° north and south of the equator. The map was commissioned in 2002 by Bob Abramms and Howard Bronstein of ODT Inc. and drafted by cartographer Mick Dyer, as a modification of the 1910 Behrmann projection. The name ''Hobo–Dyer'' is derived from Bronstein and Abramms's first names (Howard and Bob) and Dyer's surname. The original ODT map is printed on two sides, one side with north upwards and the other with south upwards. That, together with its equal-area presentation, is intended to present a different perspective compared with more common non-equal area, north-up maps. The goal is similar to that of other equal-area projections (such as the Gall–Peters projection), but the Hobo–Dyer is billed by the publisher as "more visually satisfying". To that end, the map stretches the low latitudes vertically less than Pet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mantophasmatidae
Mantophasmatidae is a family of carnivorous wingless insects within the monotypic order Mantophasmatodea, which was discovered in Africa in 2001. Recent evidence indicates a sister group relationship with Grylloblattidae (classified in the order Grylloblattodea), and Arillo and Engel have combined the two groups into a single order, Notoptera, with Grylloblattodea and Mantophasmatodea ranked as suborders. Overview The most common vernacular name for this order is gladiators, although they also are called rock crawlers, heelwalkers, mantophasmids, and colloquially, mantos. Their modern centre of endemism is western South Africa and Namibia ( Brandberg Massif), although the modern relict population of '' Tanzaniophasma subsolana'' in Tanzania and Eocene fossils suggest a wider ancient distribution. Mantophasmatodea are wingless even as adults, making them relatively difficult to identify. They resemble a cross between praying mantises and phasmids, and molecular evidence ind ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
