 The grade calculator. Fill in your current and estimated grades the calculator will calculate your estimated grade.

Extras:
 We won't be able to delve into this in detail but the first person who made a working telescope and recorded the results was Galileo. A picture of Galileo's notebook is on this site.
 The Phet lens demonstrator.
 Burning Mirrors?? Did Archimedes use a mirror (or mirrors) to burn the Roman fleet? Here are
translations of some accounts and pictures created centuries later. Here are
some links giving some perspective from the physical point of view. There's more on the Siege of Syracuse in these pages.
 Rainbows! You all might enjoy this site devoted to the scattering of light from spherical droplets of water. Check out the variablity in published indices of refraction of water.
 A "guest" appearence of the deceased rapper Tupac Shakur used the technique of Pepper's ghost. See more on ars technica.
 Snell's law waves, without the reflected wave, with the reflected wave.
 The electromagnetic spectrum.
 An animation of an e&m plane wave. Wave of an accelerating charge. Wave of an oscillating dipole.
 Light! The details if you want to see them  notes on the derivation of the wave equation of electromagnetic fields
 Notes for the BiotSavart calculation of the magentic field on axis of a solenoid.
 The 3D electric field line viewer: Download from here.
 Electric motor kits have been distributed. These details include a description of what it is all about and a description of a motor design.
 The Phet Electric Hockey!
 Here's the article by Mayo on the energy of waves at sea. For more on ocean waves try this link.
 The Doppler effect at a train station and as a costume on Big Bang Theory.
 The Doppler shift for light is used in astronomy. Here is an illustration and info on red and blue shifts. The effect is one technique for finding extra solar planets.
 An applet demonstrating the Doppler effect for sound (requires java).
 Here is the Phet simulation of interference.
 Animations of different types of wave motions.
 Here's the derivation of the equation of motion for sound.
 The grade calculator (an excel spreadsheet). Simply fill in your midterm exam grade, solution set grades (out of 10), and estimates for rest, and the calculator will calculate your estimated grade.
 There's a Chladni plate picture in the banner of this web page. Wikipedia has more on Ernst and his plates. Here's a page of his notebooks! Of course, YouTube has Chladni plate videos and there's a 2D flaming (!) demonstration shown in this video.
 Check out this comic on resonance
 A video of a wine glass orchestra or harp
 Here is the Phet simulator on resonance, used in the Guide 5 problem set.
 A resonator exhibit at the Exploratorium.
 Here's the PhET wave demo.
 A reconstruction of the black hole merger event that led to the gravitational wave discovery last year.
 The masses on springs videos: 1 and 2.
 The Citicorp Center in NYC and the Taipei 101 Tower have tuned mass dampers. I opened class on Monday February 6 asking why the Taipei 101 Tower has a pendulum inside. For more specifics see "Wind and Earthquake Resistant Buildings", some of which is on google books.
 You can see more of the Tacoma Narrows bridge in this video.There's a 2006 American Journal of Physics article by Green and Unruh on a more careful modeling of the Tacoma Narrows bridge. APS News recently had a piece on this as well, where they remind us that the original accidfent report pointed out the nonresonant behavior of the bridge.
 Fun can be had exciting the different modes of a suspension bridge. Here's an example at Messiah College.
 Check out this comic on resonance.
 In class on Monday, February 6 we went through the late time solution of driven, damped, harmonic motion. Here are the notes (pdf).
 Millennium Bridge oscillation video. See also a BCC program on this
 For a review of rotational dynamics see Chapter 10 of HRW.
 Galileo may have timed the swinging of the chandeliers in the Pisa cathedral. A picture of the ones installed in 1587, at History of Science at UO.
 Here is the PhET spring massonaspring demo. Enjoy!
