Physics Simulations make a difference in learning

There are many Physics concepts which are still very unclear to me till date. But, thanks to graphics and modeling people who have come up with many simple simulations to make us understand the concepts better. One such community is the PhET.

About PhET:
PhET provides fun, interactive, research-based simulations of physical phenomena for free. To help students visually comprehend concepts, PhET simulations animate what is invisible to the eye through the use of graphics and intuitive controls such as click-and-drag manipulation, sliders and radio buttons. In order to further encourage quantitative exploration, the simulations also offer measurement instruments including rulers, stop-watches, voltmeters and thermometers. As the user manipulates these interactive tools, responses are immediately animated thus effectively illustrating cause-and-effect relationships as well as multiple linked representations (motion of the objects, graphs, number readouts, etc.)

All PhET simulations are freely available from the PhET website and are easy to use and incorporate into the classroom. They are written in Java and Flash, and can be run using a standard web browser as long as Flash and Java are installed.

One of the Funder is National Science Foundation.

Demo Time:

You should have latest version of Java enabled in your browser.

Interesting videos on Science and Spirituality

  • Play the video and listen carefully at 1:30 - 1:40 time stamps of the video. The author talks about "..a frequency shift according to the Fibonacci series. Be prepared for 2012 December 12, when it touches the 13 cycles per second mark..".
  • "Human heart has the ability to heal you based on your belief. One's physical atoms realign in the right order to bring this change and the radiance of such a healing power spreads out and can influence the outer world as well. This is what has been said by saints and spiritual masters across the world!!"

    "One day when the entire world realizes this power of heart, it is a better world to live." Yes - I think so. What do you think?
