Applets and Videos

 

 

Note:  This is just the beginning of what will be a much longer — and better organized — list,
eventually to be linked to the demo pages.

Linear, circular, and elliptical polarization from sums of linear x and y polarization with different

amplitudes and different relative phase:

The “Retard” Physlet shows the time development of electric fields from an accelerating charge.

Applets related to color:

 

The Spectrum Applet lets you draw a spectrum consisting of 16 data points; the spectrum is "perceived" by the computer eye, which calculates three numbers: X, Y, and Z. These numbers are called the CIE primaries. These are converted to red, green and blue components that are then added to produce the resulting color. http://www.cs.rit.edu/~ncs/color/a_spectr.html

The Chromaticity Diagram and Gamut Applet introduces the notions of the chromaticity diagram and the color gamut. The chromaticity diagram is defined by the X+Y+Z=1 plane. A color gamut is a range of colors defined on the chromaticity diagram. Here you can explore the effect of adding colors together. http://www.cs.rit.edu/~ncs/color/a_chroma.html

The Color Spaces Conversion Applet demonstrates how color is represented in different color spaces and how conversion between these spaces can be done. There are many different color spaces, but only four of them - RGB, HSV, YIQ and CIE L*a*b* are presented here. Each color space, when selected, is implemented as a separate Java frame. A change to any one of them will result in the appropriate changes in the others. Note: All images are computed in real time and have been optimized to improve performance. http://www.cs.rit.edu/~ncs/color/a_spaces.html

The Color Matching Game Applet allows you to select a color space and then try to match two colors. It turns out to be rather difficult, so please be patient and carefully watch the hints. This is for those of you who have successfully run the previous applets and are mentally able to visualize each of the color spaces in 3D. http://www.cs.rit.edu/~ncs/color/a_game.html

Videos

 

 

Diamagnetism of water is easily demonstrated using a dish of water <http://www.youtube.com/watch?v=2FvWtEdY4sE> , or with a
stream of water <http://www.youtube.com/watch?v=7b-w0oWttN0> . (In the latter video, the strong attraction with the charged glass
rod is probably due to induced negative charge in the water stream, pulled from ground.
In any case, what I'm linking it for here is the last part, showing the repulsion from a magnet.)

Pyrolytic carbon <http://en.wikipedia.org/wiki/Pyrolytic_carbon>  is similar to graphite but has a parallel planar structure
with macroscopically large planes. It has the largest diamagnetic susceptibility by weight
of any room temperature material, and can be levitated above small neodymium magnets <http://www.youtube.com/watch?v=jyqOTJOJSoU> .
