Example text

We developed what was then the only commercially available, high-definition, real-time 3-D light microscope and sold it to research scientists throughout the world. I have been issued seventeen patents for 3-D microscopes, many of which have Three dimensions of information are tracked in this image of a mouse tongue. The red color labels a protein specific to smooth muscle cells, thus the red tubular shape reveals the presence of a tiny arteriole. The yellow striped fibers are muscle cells. The yellow color is created from the combination of two proteins, actin and myosin, found specifically in muscle cells.

So are these colors "natural"? Birefringence is a phenomenon of nature, so it surely must be natural. It's just that those colors can't be seen without the polarizing filters. These filters provide us with a new set of eyes for viewing nature, a fresh point of view that provides a new dimension of information. Interestingly enough, some animals, such as bees and migratory birds, see polarized light naturally. They use this special sense to navigate from place to place, even during overcast days when the sun isn't out.

The sand is usually very dry, with less than 1 percent wetness. Also the sand must have a medium grain size and be well sorted for consistent size, so that all the grains have about the same diameter. The grains are quite spherical in shape with semipolished or frosted surfaces when viewed through a low-power microscope. However, unevenness in surface roughness on the electron microscope level is an important factor for acoustic quality. The pitch of the sound is related to grain size, while the volume of the sound is related to surface texture.
