Eyes on the Earth NASA Explore Earth's Vital Signs View recent data for air temperature, carbon dioxide, carbon monoxide, sea level, ozone, ice and water. Fly along with NASA Satellites Origin of the Periodic Table I know what the periodic table looks like, but where did it come from? Whose idea was it to arrange the elements this way? He set them out in order of atomic weight, and then grouped them into rows and columns based on their chemical and physical properties. Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window.
7 Man-Made Substances that Laugh in the Face of Physics Odds are pretty good that some of you are reading this on an LCD screen while the rest of us are trying to make it out on the 13-inch monochrome monitor that came with our garage sale Commodore 64. But even with the LCD, some laptops still weigh over 10-pounds. And while that doesn't seem like much, the level of muscle atrophy experienced by the average Warcraft addict makes that weight a thousand times heavier. However, elastic conductors could fix that and make smuggling your porn collection into church even easier.
Simple animation to explain complex principles - Electronics 1, aircraft radial engine 2, oval Regulation 3, sewing machines 4, Malta Cross movement - second hand movement used to control the clock 5, auto change file mechanism 6, auto constant velocity universal joint Nuclear reactor and power plant simulation Introduction This is not a lesson like the others in Radioactivity and Atomic Physics Explained but it fits in well with the lesson on nuclear power. It is a very sophisticated simulation of a pressurised water reactor (PWR), which is the most common type of nuclear power reactor in the US but not in Europe, though the principles are very similar. Using the tour There is a comprehensive tour which goes through the workings of the reactor, starting from a consumer of electrical energy and working backwards to the reactor core itself. You can restart the tour at any time using the button at the top left of the screen.

Napoleon: Interactive Battle Simulator Game Instructions To play the Waterloo Interactive Battle Simulator, you must first choose whether to play as Napoleon (French side) or as Wellington (Allied side). The computer will play as your opponent. The Transistor Lists of Nobel Prizes and Laureates The Transistor Play the Transistor Recycler Game List of unsolved problems in physics Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail. Unsolved problems by subfield The following is a list of unsolved problems grouped into broad area of physics. Cosmology, and general relativity Cosmic inflation
Over the Top - A First World War Free Online Adventure Game Introduction Over the Top is an interactive adventure game that allows YOU to experience life in the trenches during the First World War. As a young Canadian soldier stationed somewhere along the Western Front in the late Fall of 1916, you will live through some of the excitement, despair, brutality and sheer horror of trench warfare. Over the Top is based on the real-life experiences of Canadians who lived and died in the trenches during the First World War.
