What is a rainbow? Author Donald Ahrens in his text Meteorology Today describes a rainbow as "one of the most spectacular light shows observed on earth". Indeed the traditional rainbow is sunlight spread out into its spectrum of colors and diverted to the eye of the observer by water droplets. The "bow" part of the word describes the fact that the rainbow is a group of nearly circular arcs of color all having a common center. Where is the sun when you see a rainbow? This is a good ...

ELECTRICITY Thank you for visiting our web pages on electricity! The web page and links below are designed to inform you about the ways in which we create electricity, the ways in which we use electricity, and to supply information on electricity itself. Electricity plays a big part in the lives of many people, yet few know how it actually works, so lets start with the basics: The basic unit of all matter is an atom. The atom is made of three tiny parts: protons, neutrons, and elect ...

Energy I Energy is the ability of an object to cause change. The energy of an object in motion is called kinetic energy. The word "kinetic" was derived from the Greek word for motion. The greater the mass of a moving object, the greater is its kinetic energy. A 4,000 pound Cadillac moving at 60 miles per hour has more energy that a 2,000 pound Subaru. Kinetic energy is also related to speed. The greater the speed, the greater the kinetic energy. For example, a 2,000 pound Subaru moving at 120 m ...

Earth is a complex of active physical and biological systems which interact and influence one another and change in response to energy in its various forms. There are various sources and forms of energy on Earth; some exert their influence naturally and others do so through human intervention. Energy cannot be destroyed but it ca ...

Interactive Experiments in Gravity This directory contains documents and interactive Java applets which explore aspects of both Newton's theory of universal gravitation and Einstein's general relativity. The first two installments in the series are now available. Bending Spacetime in the Basement We live our entire lives within the Earth's gravitational field, yet rarely if ever do we experience the universality of gravitation: that every object in the universe attracts and is attra ...

Celebrating 100 years of particle physics* A ThinkQuest Project created by Team Number 10380 Rahul Jain (Team Leader) and Shaheen Gandhi J.J. Thomson discovered the electron in 1897, sparking the search for more sub-atomic particles and creating the field of particle physics. We dedicate this site to him for all that his discovery precipitated. By the way, it's also the 50th anniversary of the discovery of the pion. If you are using Microsoft Internet Explorer, pages will load and the site is fully enjoyable, but some JavaScript may not work.

The Legacy of E = mc2 Einstein's big idea has been enormously influential, in ways that reach far beyond the purely scientific.

Circles of Light: The Mathematics of Rainbows How are rainbows formed? Why do they only occur when the sun is behind the observer? If the sun is low on the horizon, at what angle in the sky should we expect to see a rainbow? This lab helps to answer these and other questions by examining a mathematical model of light passing through a water droplet. Outline Objectives of the Lab How does light travel?

Relativity in a Wormhole! Introduction E=mc² does not define the theory of Relativity. Nor does this page define everything. We started our work on this page in the naive idea that we could pick a few topics and study them, cut-and-dry. Talk about a rude awakening! IT'S ALL RELATED. To understand this, you have to know that, and to know that, you must have studied these. And so it goes. The image of this page has, therefore, changed a lot from our origional concept. We still have some main ...

Library: Historical Documents: John Remsburg: Six Historic Americans: Chapter 3 Six Historic Americans George Washington by John E. Remsburg During the presidential campaign of 1880, the Christian Union made the startling admission that, of the nineteen men who, up to that time, had held the office of President of the United States, not one, with the Possible exception of Washington, had ever been a member of a Christian church. Was Washington a church member? Was he in any sense a Ch ...

Fusion Energy Mission Control Relativity Wormholes Nanotech Nanotechnology is the science of nanites, molecule-sized robots which can manipulate individual atoms. By doing this they can self-replicate and assemble any product, directly from any source of atoms available. They could turn raw sewage and dirt into a gourmet meal, they could produce a giant diamond out of a pile of coal. Just as computers have changed every aspect of our lives, Nanotechnology will do the same o ...
