Secret Worlds: The Universe Within - Interactive Java Tutorial

Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. Notice how each picture is actually an image of something that is 10 times bigger or smaller than the one preceding or following it. Earth = 12.76 x 10+6 = 12,760,000 meters wide (12.76 million meters) Plant Cell = 12.76 x 10-6 = 0.00001276 meters wide (12.76 millionths of a meter) Contributing Authors David A.

The Energy Story Energy is one of the most fundamental parts of our universe. We use energy to do work. Energy lights our cities. Energy powers our vehicles, trains, planes and rockets. Energy warms our homes, cooks our food, plays our music, gives us pictures on television. Energy powers machinery in factories and tractors on a farm. Energy from the sun gives us light during the day. Everything we do is connected to energy in one form or another. Energy is defined as: "the ability to do work." When we eat, our bodies transform the energy stored in the food into energy to do work. Cars, planes, light bulbs, boats and machinery also transform energy into work. Work means moving something, lifting something, warming something, lighting something. There are many sources of energy. The forms of energy we will look at include: Electricity We will also look at turbines and generators, at what electricity is, how energy is sent to users, and how we can decrease or conserve the energy we use.

The Mill of Time by Terry Alden by Terry Alden Part I: Celestial Cycles and Ancient Mythological Science We are on the verge today of a much greater appreciation for the scientific achievements of the world's most ancient civilizations and an understanding of the workings of the ancient mind. At a time when it is still fashionable for scientists to dismiss the possibility that the learned men of remote antiquity, long before the classical-period Greeks or the later Romans, could have known about phenomena like precession (the extremely slow wobble of the Earth's axis of rotation) without modern instruments, or about the spherical shape and dimensions of our planetary spacecraft or its orbit about the Sun as the center of a solar system, a few lone investigators have recently found traces of a very high degree of scientific sophistication and knowledge of the natural world preserved in a metaphorical code which we call myth. Campbell once asked an interviewer he didn't particularly like to give an example of a myth.

UFOs in Movies, Books and Television - History of the Flying Saucer By Phil Patton, with additional reporting by Davin Coburn, Erin McCarthy, Joe Pappalardo and Erik Sofge December 18, 2009 3:24 AM On June 24, 1947, pilot Kenneth Arnold claimed he saw gleaming aircraft he later described as "saucerlike objects." He had no photos to bolster the first and most famous report of a flying saucer. In Fate magazine, Arnold wrote: "I would have given almost anything that day to have had a movie camera." His vision of saucer-shaped craft was quickly embraced by popular culture, showing up in comics, movies, even children's toys. <a href =" >Do you think that UFOs are alien spacecraft? UFO sightings evolve with the culture. In recent years, most UFO reports have grown far less sensational; many sightings these days simply describe lights in the sky. Arnold regretted not having a camera at hand during his sighting.

Difference Between Isotopes and Isobars Isotopes vs Isobars Atoms are the small building blocks of all existing substances. There are variations between different atoms. Also, there are variations within the same elements. Isotopes are examples for differences within a single element. Isotopes Atoms of the same element can be different. 1H – no neutrons, relative abundance is 99.985% 2H- one neutron, relative abundance is 0.015% 3H- two neutrons, relative abundance is 0% The number of neutrons a nucleus can hold differs from element to element. A mass spectrometer can be used to get information about isotopes. Isobars Isobars are atoms of different elements with the same mass number but their atomic numbers are different. Related posts:
