Universities with the Best Free Online Courses Free online courses are offered by real schools. Learn which courses are available, what topics they cover and which ones lead to real college credit. Online Courses for Credit All of the schools listed below are well-known universities with a variety of free online course offerings. These classes are typically offered as part of an OpenCourseWare (OCW) project. Materials can be accessed at any time and the coursework is self-directed, though no academic credit is awarded for course completion.

Learn Science at Scitable Classrooms Scitable Classrooms are rich research spaces that allow you to provide your students a custom online reading list, threaded discussions, news feeds, and research tools. For your online reading list, you can pull from our library of more than 500 expert-authored, peer-reviewed, readable explorations of key concepts in life sciences commissioned and edited by our team of Nature Publishing Group staff editors. Designed to guide students beyond memorization of scientific facts into a deep understanding of the scientific method, the experimental tradition, and the nuances of data analysis, our articles help students learn to think scientifically.

25 Awesome Virtual Learning Experiences Online - Virtual Education Websites Just because you’re online doesn’t mean that you can’t experience the world first-hand — or as close to first-hand as possible. Here are websites that feature virtual learning experiences, exposing online visitors to everything from history to geography, astronomy to anatomy, literature to government. 7 Wonders Panoramas – 360-degree views of the Seven Wonders of the World.

5 Really Weird Things About Water Water, good ol' H2O, seems like a pretty simple substance to you and me. But in reality, water - the foundation of life and most common of liquid - is really weird and scientists actually don't completely understand how water works. Here are 5 really weird things about water: 1. Check out my cool home design on Autodesk Homestyler! © 2013 Autodesk, Inc. All rights reserved.

Starting the pendulum from a slightly different initial condition would result in a completely different trajectory. The double rod pendulum is one of the simplest dynamical systems that has chaotic solutions. Chaos: When the present determines the future, but the approximate present does not approximately determine the future. Chaotic behavior can be observed in many natural systems, such as weather and climate.[6][7] This behavior can be studied through analysis of a chaotic mathematical model, or through analytical techniques such as recurrence plots and Poincaré maps.

Math, Physics, and Engineering Applets Oscillations and Waves Acoustics Signal Processing Electricity and Magnetism: Statics Electrodynamics Quantum Mechanics Science Matters Yah, I know some of us are winding down from schooling for the summer months, but I can’t help but stay on the lookout for resources I know I’m going to be needing again all too soon. I’ve come across some interesting science things of late that I want to check out – perhaps you, too, can find something useful.

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.

The Rotary Piston Array Machine -- Air-Sea Temperature Difference Engine -- Solarthermal Power Generator The Rotary Stirling Engine The Wave Pump Heat Engine With No Compressor Portable Tent Platform The rotary piston array (RPA) is the possibly most compact and most elegant machine to transform the volumetric change of gas into shaft work and vice versa. It can be used as pneumatic motor, steam engine, gas compressor, vacuum pump and the like, but also as part of new heat or combustion engines which – like the Stirling engine – open new ways to harvest renewable energy.
