1 Million Spiders Make Golden Silk for Rare Cloth A rare textile made from the silk of more than a million wild spiders goes on display today at the American Museum of Natural History in New York City. To produce this unique golden cloth, 70 people spent four years collecting golden orb spiders from telephone poles in Madagascar, while another dozen workers carefully extracted about 80 feet of silk filament from each of the arachnids. The resulting 11-foot by 4-foot textile is the only large piece of cloth made from natural spider silk existing in the world today. “Spider silk is very elastic, and it has a tensile strength that is incredibly strong compared to steel or Kevlar,” said textile expert Simon Peers, who co-led the project.
Big Bang According to the Big Bang model, the universe expanded from an extremely dense and hot state and continues to expand today. The graphic scheme above is an artist's concept illustrating the expansion of a portion of a flat universe. The Big Bang is the scientific theory that is most consistent with observations of the past and present states of the universe, and it is widely accepted within the scientific community. It offers a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background, large scale structure, and the Hubble diagram. The core ideas of the Big Bang—the expansion, the early hot state, the formation of light elements, and the formation of galaxies—are derived from these and other observations.
Euclid: The Game - Tutorial Goal: Construct a line segment from A to B. ✓ Construct a ray from C to D. ✓ Construct a circle with center E and radius EF. ✓ Construct a circle with center F and radius EF. ✓ Construct a (black) point at the intersection of AB and the ray CD. ✓ Hint: Hold your mouse on a tool to get a brief instruction how the tool works.
Why time appears to speed up with age (idea) In a groundbreaking article, T. L. Freeman discusses the relationship between actual age and effective age1. His conclusion is that the passing of the years goes faster as we grow older. ATOMIUM 2013 INSPIRATION: SKETCHING (3/3)One of my favorite step of the creative process is to doodle for hours to understand the structure, shape and space I’m working with. In this case I drew the low poly planet several times using the stippling technique.This drawing was shown at an exhibition at Muriel Guépin gallery in NYC last April, and also Art Basel in June 2013, and the piece is available through the gallery. joanielemercier:
Alphabet The letters in the Greek alphabet presented below are used for printed Ancient Greek texts. The earliest Greek texts that have survived were written with a radically different script called Linear B. For a detailed and wonderfully well argued discussion of the origins of the Greek alphabet, see Roger D. Woodard’s book, Greek Writing from Knossos to Homer. You can find fonts for displaying or writing Greek text as well as utilities for converting older fonts to the new Unicode standarde on our fonts page. Three sets of pronunciation suggestions are given in the table below: first the pronunciation of each letter in Modern Greek, then the reconstructed Hellenistic Koine pronunciation, and finally the reconstructed pronunciation for the Classical period (before about 350 BCE).
NASA Weighs In on Mayan Apocalypse on YouTube The title says it all, "Just Another Day." The official YouTube channel for NASA's Jet Propulsion Laboratory has released its stance on the much publicized December 21, 2012 Mayan doomsday scenario. (VIDEO BELOW) In a nutshell - it's safe to make plans for December 22. NASA's Don Yeoman's gives insight that he say debunks some end of the world scenarios diehard Mayan Apocalypse observers believe. History of the alphabet The history of alphabetic writing goes back to the consonantal writing system used for Semitic languages in the Levant in the 2nd millennium B.C. Most or nearly all alphabetic scripts used throughout the world today ultimately go back to this Semitic proto-alphabet. Its first origins can be traced back to a Proto-Sinaitic script developed in Ancient Egypt to represent the language of Semitic-speaking workers in Egypt. This script was partly influenced by the older Egyptian hieratic, a cursive script related to Egyptian hieroglyphs. Mainly through Phoenician and Aramaic, two closely related members of the Semitic family of scripts that were in use during the early first millennium BC, the Semitic alphabet became the ancestor of multiple writing systems across the Middle East, Europe, northern Africa and South Asia.
Ancient Greece The Parthenon, a temple dedicated to Athena, located on the Acropolis in Athens, is one of the most representative symbols of the culture and sophistication of the ancient Greeks. Ancient Greece was a Greek civilization belonging to a period of Greek history that lasted from the Archaic period of the 8th to 6th centuries BC to the end of antiquity (ca. 600 AD). Immediately following this period was the beginning of the Early Middle Ages and the Byzantine era. Included in ancient Greece is the period of Classical Greece, which flourished during the 5th to 4th centuries BC. Classical Greece began with the repelling of a Persian invasion by Athenian leadership. Because of conquests by Alexander the Great, Hellenistic civilization flourished from Central Asia to the western end of the Mediterranean Sea. Chronology
