Simple Mechanics Cams The basic principle of the cam is to turn a circular motion into a linear one. This is referred to as reciprocating movement. In it's simplest form you turn a handle to make something move up and down. The cam-follower is connected to, and part off, a shaft known as the Push-Rod.

The Story of Mathematics - A History of Mathematical Thought from Ancient Times to the Modern Day Follow the story as it unfolds in this series of linked sections, like the chapters of a book. Read the human stories behind the innovations, and how they made - and sometimes destroyed - the men and women who devoted their lives to the Story of Mathematics.

I'm excited to have Edutopia's new Web Video Strategy Coordinator, Keyana Stevens, guest curating today's Five-Minute Film Festival. You may be seeing more of Keyana in this space moving forward, I'm sure you'll love her picks as much as I do!
Math, Physics, and Engineering Applets Oscillations and Waves Acoustics Signal Processing Electricity and Magnetism: Statics Practical Physics This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Free Online Physics Courses Get free online Physics courses online from the world's leading universities. You can download these audio & video courses straight to your computer or mp3 player. The collection includes introductory physics courses recorded at top universities (e.g. Yale, UC Berkeley & MIT). You will also find more specialized courses covering topics like Einstein's theory of Relativity, black holes and string theory, not to mention some classic lectures by Richard Feynman. For more online courses, please visit our complete collection of Free Online Courses.
Energy & Machines Activities and Games Free Downloads Physical Science Sorry this category is so small. I don't often get stuck in situations where I have to generate physical science resources. (My inventions always come about as the result of finding myself in a teaching situation for which I can't find adequate resources.) Energy Science Xplained Science Xplained is a collection of video podcasts that tell the stories of the science behind everyday topics. Dr. Ainissa G. Ramirez, self-proclaimed science evangelist and associate professor of mechanical engineering and materials science at Yale University, is the dynamic host of the series. Filter Resources by Grade: HyperPhysics Concepts About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation.
Evolution of the Universe - GigaPan Time Machine Jump to: From GigaPan Time Machine Direct Cosmological Simulations of the Growth of Black Holes and Galaxies This timelapse shows the distribution of matter in a simulated universe on large scales. What causes lift? Yesterday, I wrote about one of my favorite kinds of clouds: Kelvin-Helmholtz clouds, also called fluctus clouds. You can call them wave clouds, because that’s what they look like: Waves breaking over a beach. I also embedded a video from Sixty Symbols explaining them, but during that explanation the scientist, Mike Merrifield, made a bit of a flub: He said that with an airplane wing, lift is generated because air is moving faster over the top of the wing than the bottom.
News - NASA Space Telescopes Provide a 3D Journey Through the Orion Nebula Astronomers and visualization specialists from NASA’s Universe of Learning program have combined visible and infrared vision of the Hubble and Spitzer space telescopes to create an unprecedented, three-dimensional, fly-through view of the picturesque Orion Nebula, a nearby star-forming region. Viewers experience this nearby stellar nursery “close up and personally” as the new digital visualization ferries them among newborn stars, glowing clouds heated by intense radiation, and tadpole-shaped gaseous envelopes surrounding protoplanetary disks. Using actual scientific imagery and other data, combined with Hollywood techniques, a team at the Space Telescope Science Institute in Baltimore, Maryland, and the Caltech/IPAC in Pasadena, California, has created the best and most detailed multi-wavelength visualization yet of this photogenic nebula. The fly-through enables people to experience and learn about the universe in an exciting new way.
Earth - Travel at light speed from the Sun to Jupiter Sit back and take a ride from the Sun to Jupiter, at the speed of light. Animator Alphonse Swinehart made this video to illustrate the sheer mind-boggling scale of the solar system. It isn't completely accurate, as Swinehart admits. "I've taken liberties with certain things like the alignment of planets and asteroids," he says, "but overall I've kept the size and distances of all the objects as accurate as possible."
