"Where's my Eraser, Bud?"
When a pencil is placed behind a glass of water, the end of eraser disappears. However, the eraser is visible on the opposite side of the glass. The pencil appears to be severed where it meets the glass. This optic phenomena is due to the glass of water behaving like a converging lens. The image produced is real, inverted, and has a magnification greater than one. The eraser appears to be stretched. This is due to the round shape of the glass, which allows the water to take a convex shape. The law of refraction is obeyed because when light enters a material, the water glass which has a greater index of refraction than air, the speed of light is slowed. Because of the this, the light rays are bent, causing the inverted, magnified eraser.

My whiteboard. It was a pain to install, but I am enjoying the benefits of it. I was doing some physics homework to break it in. Day 195 of the project.
A close up photo featuring the logo of the triode amplifier manufacturer, Continental Electronics. This piece of equipment provides power for one of the segments of Fermilab's LINAC (linear particle accelerator)
Set Description: For fun, myself and a group of friends took a grade-school like field trip of Fermilab, the nation's biggest particle physics laboratory and home of the Tevatron particle accelerator. Here are some photos.

This exercise in creative energy features a variety of short scenes, all original material by Bethany students and theatre faculty written, rehearsed, and readied in three weeks. Performed September 19-21 in the Sigurd K. Lee Theater of the Ylvisaker Fine Arts Center.

"Blinded by the Light"
Contrived
This picture, taken at a Nine Inch Nails concert, illustrates a lens flare of a purple light. When the light from this stage light projected through the lens of the camera, there are a couple of things that may have happened to it that to cause this phenomenon. Internal reflection may have occurred in the lens before it transferred the image. Internal reflection is when the light entering the lens hits at a large angle away from the normal. The light reflects inside of the lens before it exits at a different angle than the rest of the rays from the object making it much brighter. Another reason lens flares occur is due to aberrations in the material that the lens is made of. An aberration is a defect in the surface or material of the lens. This defect may send the light scattering in a different way than the rest of the image, causing the flare to occur. If you'll notice, there is a flare around the source of the stage light, and several smaller flares as you move down and to the left. These smaller flares help show that the lens is also diffracting the purple light, breaking it apart into its components.
