Dock Tricks Water: The Great Mystery Fascinating movie spans the globe to reveal recent discoveries about water, the most amazing yet least studied substance in the world. Witness as researchers, scientists, philosophers and theologians try to understand this unique liquid and all its miraculous properties still waiting to be discovered. It was there that Heisenberg and Bohr came to Einstein to tell him it looked like the minds of the researchers were affecting the results of the experiments. Mind was inexorably linked to matter.
Columbia Engineers Prove Graphene is Strongest Material July 21, 2008 Columbia Engineers Prove Graphene is the Strongest Material Research scientists at Columbia University’s Fu Foundation School of Engineering and Applied Science have achieved a breakthrough by proving that the carbon material graphene is the strongest material ever measured. Graphene holds great promise for the development of nano-scale devices and equipment. It consists of a single layer of graphite atoms arranged in a hexagonal lattice, similar to a honeycomb. As a two-dimensional material, every atom is exposed to the surface.
Did You Know? – Fun Ocean & Scuba Facts -Largest Ecosystem -The whole spectrum above blue is filtered. Not just red and yellow, (which should actually be red and GREEN.) The colors of the world aren’t quantized into three primary colors. [2.0] Refining The Art v2.3.1 / chapter 2 of 13 / 01 nov 12 / greg goebel / public domain * The invention of frequency analysis made simple monoalphabetic substitution ciphers much too easy to crack, and led cryptographers to design new and more formidable codes and ciphers over the next centuries; the contest between codemaker and codebreaker escalated to a higher level. In the meantime, the general public began to recognize the use of codes and ciphers, and simple cryptosystems came into popular use. * The Arab world was well ahead of the West in cryptanalysis, but in European monasteries, monks engaged in analysis of Biblical texts kept interest in cryptology alive in the West.
Jacob's Well, Wimberley, Texas Jacob’s Well is a significant karstic spring, the largest perennial spring in the Texas Hill Country. It flows from the most extensive underwater cave in Texas, opening in the bed of Cypress Creek, a few miles north of Wimberley, Texas.The twelve foot (four meter) diameter mouth of the cave serves as a popular swimming and water recreation spot for the local land owners whose properties adjoin Cypress Creek. From the opening in the creek bed, Jacob’s Well descends vertically for about thirty feet (ten meters), continuing from there at an angle as a series of chambers separated by narrow, often deeply silted and unstable necks, ultimately reaching a depth of at least one hundred and twenty feet (forty meters). The Relativity of Wrong by Isaac Asimov by Isaac Asimov I received a letter from a reader the other day. It was handwritten in crabbed penmanship so that it was very difficult to read. Nevertheless, I tried to make it out just in case it might prove to be important. In the first sentence, he told me he was majoring in English Literature, but felt he needed to teach me science.
Scaling previous index next PDF Michael Fowler, UVa 10/12/06 Galileo begins “Two New Sciences” with the striking observation that if two ships, one large and one small, have identical proportions and are constructed of the same materials, so that one is purely a scaled up version of the other in every respect, nevertheless the larger one will require proportionately more scaffolding and support on launching to prevent its breaking apart under its own weight. He goes on to point out that similar considerations apply to animals, the larger ones being more vulnerable to stress from their own weight (page 4): Who does not know that a horse falling from a height of three or four cubits will break his bones, while a dog falling from the same height or a cat from a height of eight or ten cubits will suffer no injury? ... and just as smaller animals are proportionately stronger and more robust than the larger, so also smaller plants are able to stand up better than the larger.
Culture Vaults : Resonant Frequencies and the Human Brain One of the great revelations of 20th century science is that all existence can be broken down into simple wave functions. Every photon, energy emission, and elementary particle rings with its own unique wave signature. When we see a color, we are actually seeing a distinct frequency of visible light. When we hear a sound, our eardrums are actually being vibrated by subtle waves in the air molecules around us.
