Mobile Unit Shows Uses Of Atomic Energy In Peace
Q.
An added attraction for the big weekend will be the "Atoms for Peace" mobile unit, located in the parking lot behind Marvin Hall.
The display is a self-contained, walk-through exhibit housed in a modern bus. It is the latest in a series of travelling atomic energy exhibits prepared by the U.S. Atomic Energy Commission as part of a program to inform citizens about atomic energy.
A series of panels, animated by the spectator, explains research and development in the atomic energy field. The panels cover a range from mining to refining radioactive ores.
The visitor will see many of the uses of radioisotopes in medicine, agriculture, and industry. The exhibit also contains samples of radioactive ore, simulated fuel elements, reactor control rods, and radiation-
detection devices.
The animated panels show how a nuclear reactor, using atomic fuel can produce heat that is used to convert water into steam. The steam activates an ordinary turbine engine, resulting in the production of electrical power.
Another of the panels is concerned with radioactive elements and compounds in fertilizers. They will show how the growing corn plant absorbs all the phosphate necessary to its growth.
Also shown will be the ways in which the atom can aid the physician and his patient. One of the uses of treatment of cancer and other diseases is by machines which emit beams of intense radiation that destroy the diseased tissue. This machine will be shown in one of the panels.
This Class Looks At Stars In The Heavens, That Is
Several nights this year small groups of star-gazers have been seen atop Lindley Hall.
Unlike numerous other groups who claim this same avocation—but generally gather in the Potter Lake area—the Lindley observations are with the full authorization of the University.
The watchers are members of the Astronomy 1 class. They meet to observe the stars, planets and moons with N.W. Storer, associate professor of astronomy. They use two sizes of refracting telescopes, a 3-inch and a 6-inch.
The 6-inch telescope is used for looking at the stars, planets, and moons of the planets. The 3-inch is used for determining exact time from the stars.
Wants Limit On Enrollment
FREDERICK, Md.—(IP)—In a student opinion poll to determine the feasibility of limiting Hood College enrollment to 600 students, 305 students replied "yes" while 29 answered "no." Five remained undecided. Ninety-four per cent of the students stated that they chose Hood because it is a small college.
The Carnegie Corporation says mathematics is the least popular high school subject offered today.
When Precise Time Is Needed Prof. Storer said that the measure of precise time is not necessary for ordinary situations, but you could not tell the time of the next eclipse without it.
Later this semester the students of beginning class in astronomy will be given a chance to view the heavens through the University's 27-inch reflecting telescope.
Besides being used for direct observation of the heavens, this big telescope is used for research. It can photograph the stars, measure their brightness or tell their chemical composition.
To Observe Comet
A high point of this semester's work will be the observation of the Arend-Roland comet sometime in the middle of April.
The courses in astronomy are in the physics and astronomy department.
A total of 17 courses in astronomy are offered.
"Not very many students take courses after the beginning course," Prof. Storer said. "The reasons are not hard to see. With a major in astronomy you can either go into research work or teach it."
"It is a very interesting hobby," he said, "and helps answer some of the questions about the universe."

KU Scientists Study Hot Atoms
Welcomes you to the
KANSAS RELAYS
Good Luck KU.
Starting with four empty labs last June, student and faculty research workers have advanced to the point of running into space difficulties.
'Hot' Atom Research
The labs, which were empty less than a year ago, now contain between 10 and 15 thousand dollars worth of equipment and provide working space for eight persons under the direction of F. S. Rowland, assistant professor of chemistry.
The research is being done in the field of hot atom chemistry, the study of the reactions of energetic radioactive atoms and ions.
"Our primary problem is to find out what happens when energetic atoms react," Prof. Rowland said. "Secondarily we are exploring the possibilities of producing radio active tracer materials.
way a person studying the plant or animal is able to tell which part of the organism utilizes the material. In cancer research it is often useful to know which materials are used by the affected areas.
"In this second phase we have an informal connection with the M.D. Anderson Tumor Hospital in Houston, Tex. They send us samples of materials used in cancer research. With these samples we can try our methods of labeling," Prof Rowland continued.
He explained that radioactive tracers are materials which can be followed as they move through a living plant or animal by measuring the amount of radioactivity present in any part of the organism. In this
"The radioactive materials we now use are tritium and carbon 14, which we get from Brookhaven National Laboratory in Upton, N.Y. These materials retain their activity for long enough periods to permit us to spend time getting them through the mail." Prof.
N.Y.U. Adopts New Course Plan
NEW YORK, N.Y.—(I.P)—A new program of coordinated liberal studies has been adopted by New York University's Washington Square College of Arts and Science, Dean Thomas Clark Pollack said recently. It will take effect in September.
Concerned with basic required courses of freshman and sophomore years rather than with major or minor fields, the program is the result of some years of experiment with undergraduate curriculum.
Replacing the old required-elective program, the new program sets up a requirement of coordinated courses within each of three major divisions for all students in their first two years. The divisions are humanities, natural sciences, and social sciences.
Rowland said. "Another material we want to use is radioactive bromine, but this retains its activity for only one week."
Prof. Rowland said plans have been made with Worth Seagondollar, associate professor of physics, of the physics department to use their Van de Graaff generator to produce radioactive bromine for use in the experiments.

The project is being financed by the Atomic Energy Commission and the University. During the current year the AEC has provided $28,-000 for new equipment and salaries for research assistants.
Working on the project are Dr. Jung Kong Lee, research associate in chemistry; Jack G. Kay, St. John, Larry Haskin, Baldwin, Raymond M. White, Satanta, Ernesto Ureto, Monterey, Mexico, and Lawrence J. Mulac, Santa Monica, Calif., all graduate students; Burdon C. Musgrave, Lawrence senior, and Barbara McCarty, Lawrence junior.
Now This Looks All Right
GETTYSBURG, Pa. —(IP)—The Gettysburg College faculty has accorded second semester seniors voluntary chapel attendance, exemption from final exams in their major fields, and voluntary class attendance for any senior in his second semester who has a 2.0 point average.
The U. S. Air Force uses nearly four million gallons of fuel per day.

Good Luck to Coach Easton and the Track Team.
Yes, top performance is a must at any track meet. Your car, too, can be a top performer if you give it Cities Service care at FRITZ CO. After the Relays you'll enjoy more
care-free driving home if you make your last stop in Lawrence at FRITZ CO., downtown-near everything.
