Fluid Dynamics of Paper Making
Measurements of the three-dimensional motion of fibers in turbulent fluid flow are helping us understand the multiphase flows involved in making paper.
Coloring INSIDE The Lines
Have you ever wondered why shining light on a glass of water causes rainbows to appear? Or noticed the colors that reflect from a CD or DVD? In this lesson, you will make an instrument called a spectroscope that can separate light into its hidden components. You will also be able to use the spectroscope to understand why different colored objects and light sources appear the way they do.
This photon walks into a crystal . . .
When light strikes a material, electrons may be ejected from the material. This is called the photoelectric effect, and it’s the basis for many different technologies that convert light energy into electrical energy to generate current. In addition, the photoelectric effect is useful to scientists studying novel materials.
