  1. Hmmm, not able to take a look as I don't have a NY Times login... perhaps we can find this somewhere else.
  2. Very cool -- yes. And gotta love her duds... but this is another Moog Music April Fool's joke: http://www.wired.com/underwire/2011/04/polyphonic-theremin/
  3. Great insight into the physics of the sweet spot and waves... not so sure about the Yankees pitching this year, though...
  4. Some of those look pretty painful!
  5. Wow, never thought my MacGyver Magnetostriction video would gain an audience! Now to put a video together on superconducting magnetic levitation...

    Help needed!!

    See forum post: http://www.aplusphysics.com/forums/showthread.php?185-Web-Assign-Electric-Potential&p=319&posted=1#post319

    A recap on Gauss' Law

    Nice synopsis... isn't it amazing how writing about what you've learned forces you to really organize and understand?
  9. Whew! It’s been a long and challenging project, but I am thrilled to announce that the APlusPhysics.com Regents Physics course tutorial has been completed (well, at least the first revision). I’ve been done with the tutorial less than 20 minutes, and already I’m making notes on additions, modifications, and enhancements, but I think it’s worth taking a moment to step back and look at everything that’s been accomplished. [ATTACH=CONFIG]96[/ATTACH] A year ago I had never created a web page, and didn’t know the difference between HTML and ELMO. But, with a vision to create a resource sp

    Physics in Wegmans

    That is an excellent reaction time... just remember when doing your calculations that you need to convert 3.5 feet to meters first! (3.5 feet = 1.07m) Or, to be more accurate, since the box only fell about 2.5 feet, the displacement of the box was closer to 0.76m. Now how fast was your reaction time? :egg)
  11. Outstanding point. eBay here I come!
  12. And all for the amazingly low price of only $500!!! http://www.instrumentpro.com/P-MOOETPLUS?source=CJ&AID=10362375&PID=1095380
  13. Almost like you knew what you were doing... I hope you'll continue to give him a bit of a hard time about this! :wave)
  14. From New Scientist Magazine A BALL spinning in a vacuum should never slow down, since no outside forces are acting on it. At least that's what Newton would have said. But what if the vacuum itself creates a type of friction that puts the brakes on spinning objects? The effect, which might soon be detectable, could act on interstellar dust grains. In quantum mechanics, the uncertainty principle says we can never be sure that an apparent vacuum is truly empty. Instead, space is fizzing with photons that are constantly popping into and out of existence before they can be measured directly
  15. My goodness. That much energy would power an awful lot of Tickle-Me-Elmo's!

    Formulas!

    I'll see if I can't find a way to "Sticky" a link to this post... another you can do is treat it as a "group" blog, where more than one person can write/edit/post to it. I believe you can play with the settings from the top navigation bar where it says "blog settings." I'll do a bit more research, but I know that capability comes with our blogging/messaging software. Just as an aside, I can't begin to tell you guys how thrilled I am with the effort and thought you're putting in to your posts. Not only are you finding fun and unique physics applications, you're also building tools to hel

    Superbowl

    Great physics demos notwithstanding, it was a very entertaining game... even for a Steelers fan painfully observing his team find new and exciting ways to snatch defeat from the jaws of victory.
  18. Anyone who can prove Santa is real with physics must know their stuff!

  20. That'd wake you up in a hurry!

    Formulas!

    Great idea moe.ron!!! I think this will be a terrific asset for your class as well as classes to come. Perhaps when it's finished we can blow it up into a giant poster too. Question... did you mean to write Fr for the torque in this equation? Thanks for this valuable post!
  22. This could be a very challenging theoretical problem... or a very simple experiment with a force sensor. :-)

    Physics of Running

    Terrific analysis of many of the energy conversions in the human body!
