Show Atoms in Action The first motion pictures of the actions of single atoms have been produced by two University of physicists, Albert V. Chicago Crewe and Michael Isaacson. In 1970 Crewe became the first scientist to see a single atom. He viewed it through a scanning electron microscope of his own design. With this instrument, and others like it, Crewe and Isaacson and their colleagues at the University can see uranium atoms placed on a specimen of carbon 50 angstroms of a millionth of an thick (one-fift- h inch). In order to see the atoms in microscope operates with a magnification of 10,000,000. We thought, said Crewe, that the atoms might just sit there, but they try to interact with the carbon and with each other and move around quite a lot. This peculiar activity shows up clearly in the film." The short film is significant, both historically and scientifically. It is the first time that man has even the tiny building seen atoms moving in blocks of all matter their natural state. The film, which is the forerunner of others like it, view of will provide a science-ey- e how atomic and molecular structures hook together. In time, this information may provide answers to medical and chemical questions and will help untangle structures basic to such fields .as virus and materials technology research. Albert V. Crewe is Dean of the Division of the Physical Sciences at The University of Chicago, and Professor in the Department of InPhysics, the Enrico Fermi Bioof the Department stitute, physics, and in the College. Michael Isaacson is Assistant Professor in the Department of Physics, the Enrico Fermi Institute, and in the College. He is an Alfred P. Sloan Research Fellow. The. work described here is supported in part by the United States .Energy Research and Development Administration (ERDA). The scream of a siren commonly warns of a nearby emergency vehicle. But, cautions a team of acoustical scientists, that warning if often dangerously incomplete. From a sirens sound alone, a drive cant always determine the position or direction of an approaching emergency vehicle. And, without this critically important information, any snap decision as to stops, turns, acceleration, or deceleration may result in disaster. Visual identification of an emergency vehicle is vital for totally safe evasive maneuvers, claims the research team. Richad C. The two scientists Potter and Hsien-shen- g Pei of Bolt Beranek and Newman, Inc., Camcame to bridge, Massachusetts their conclusions after tests to develop more effective sirens for police cars, ambulances, and fire engines. A group of blindfolded subjects first listened to a randomly positioned siren while seated in the open air, then in a car with an idling engine. In the open air, subjects correctly located the sirens position 91 percent of the time. In the car even with the windows open they became almost completely confused, correctly identifying the sirens location a mere 25 percent of the time. Particularly significant was the subject's inability to pinpoint a siren either directly ahead or behind the test car two positions emergency vehicles are likely to take in actual urban and suburban circumstances. Only 18 percent of their judgements were correct in this situation, not much better than chance guessing, the researchers claim. 1 These tests underscored the potentially lethal auditory difficulties THE SALT LAKE TIMES FRIDAY, JULY 2, 1976 Page Eight Solons Sponsor Reform Act Over 130 legislators have sponthe Consumsored or er Communications Reform Act of 1976 which was recently introduced into Congress.

Also, internal noise such as radio, air conditioner, and windshield wipers might complicate the total sound heard by the driver. As a result, it can be difficult for a driver to dtermine the emergency vehicles location or direction.

There is no mystery connected with matching the right oil for your engine. That seldom read owner's manual in your glove compartment has the answer. Pay attention to it because late model cars have emission controls that require higher operating temperatures and a better quality of oil. It's important that you spend your petroleum dollars wisely. Adding a quart of oil to an engine with dirty oil really doesnt do much for your car. Again, follow your manual on how often you change oil. Normally, six months is about time for a change regardless of the mileage. Short trips are much rougher on an engine than long hauls. Finally, when you change the oil, change the filter. Replacing the oil without replacing the filter is like adding new oil to a worn out supply. Deceased.

Although consisting largely of rainbow trout, the stocking also includes brown and cutthroat trout, grayling and brook trout. Long before the fishing season is even thought of by most fishermen, Division Fisheries personnel are planning and working to provide the complex of Utah fishermen with adequate fish and plenty of enjoyment. The state now operates 11 hatche eries and employs 38 workers and 20 part-tim- e helpers. In the average year, these workers raise the approximately 13.5 million trout that are stocked in Utah. That is the equivalent of bout 800,000 pounds of fingerlings and catchables. Planting The Division attempts to break its catchable plantings into three periods over the summer. Just prior to the opening, if snow, ice and run-of- f conditions permit, most season general fishing areas are supplied. The other periods are the July 4 period and, again, about Labor Day. Reservoirs are usually planted once a year with typical three-inc- h fingerling in an effort to utilize the lakes natural (food production) potential to help grow the fish. These fingerling will enter the catchable size classifiction (nine to ten inches), in most waters, the following season.

In addition to planting the streams and reservoirs of the state, the Division also utilizes its fixed-win- g aircraft to plant many of the smaller lakes in high alpine areas like the Uninta and Boulder Moune tains. One plane is used from three to four weeks to plant 500,000 to 800,000 brook and cutthroat trout in these upper lakes. Because of the colder weather stocking in the mountains usually takes place from July through August. To effectively transport the large numbers of fish planted each year, the Fisheries Section maintains a fleet of specially equipped trucks. Two big tank trucks, capable of full-tim- moving between 1,500-3,00- 0 pounds of live fish, are used to transport large quantities to various locations in the state. In addition, each of the 11 hatcheries has one or two smaller tank trucks that carry 300-60- 0 pounds of live fish. Last year, fish culture personnel drove over 225,000 miles in their efforts. The Hatchery Hatcheries raise three different size fish for planting in various conditions. Obviously, the bigger the fish, the longer its stay in the hatchery and the greater the cost of raising it. Most widely used are the three-inc- h fingerling. The advanced fingerling, which is approximately five inches in length, is used in areas where rough fish populations compete with the trout for food and space. The additional size increases their chance of survival to maturity. The third size, already mentioned, is the r t V i jt T I. !
