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. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física.

Public Library of Science Interactive 3D model of Solar System Planets and Night Sky 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. Hint numbers Each part of the simulation has a hint number that you can click to see a description of its function. The skill test Once you're familiar with how to use the reactor you can see whether you can control the reactor so that the power output matches the demand from the city.

I was thinking for a few days about whether I should post this article or not. This is just for your information. (Click on images to enlarge) The latest satellite data establishes that the North Atlantic Current (also called the North Atlantic Drift) no longer exists and along with it the Norway Current. The thermohaline circulation is sometimes called the ocean conveyor belt, the great ocean conveyor, or the global conveyor belt. Dr. A Normal Gulf Stream taken from 5 September2004.

How did life originate? How did life originate? Living things (even ancient organisms like bacteria) are enormously complex. However, all this complexity did not leap fully-formed from the primordial soup. Instead life almost certainly originated in a series of small steps, each building upon the complexity that evolved previously: Simple organic molecules were formed. Multicellularity evolved.

View the latest Image of the Day Learn The History Of Physics In 4 Minutes Aristotle was wrong. He claimed that heavier items fell faster than lighter items. Had he actually tested the theory, using a high-tech tool as sophisticated as a ladder, a ledge, or a cliff, he’d have immediately realized that it couldn’t possibly be true. Because Galileo did test the theory, and he found that balls of various mass fell at the exact same rate. Well, at least that’s what happened according to this fantastic animation directed by Åsa Lucande for BBC Science. [Hat tip: neatorama]
