Physics Color 'Gimmick' Baffles By Inverting Words
By RICHARD TATUM
Equipment used in atomic research and a new "invention" called a selective color inverter are feature displays of the physics department at the Engineering Exposition.
The selective color inverter is constructed of lucite, wire, and wood, and was designed solely for the purpose of testing intelligence. All words seen through the viewer of the device printed in any color other than red appear inverted. Words printed in red remain upright.
The inventor, who wishes to remain unknown, says the gimmick is of no practical value. So far its main reason for existence has been to puzzle physics professors and graduate students. Most have remained mystified while trying to figure out just how the cylindrical piece of lucite manages to invert some colors and leave others upright.
One graduate student is said to have looked at the inverter for 36 hours without discovering its secret. This display is in in 109 Marvin hall.
The Van de Graaf electrostatic generator, used to create artificial radioactivity, will be on display in Blake annex A. The generator will be explained and demonstrated to the public by members of the physics department.
The electrostatic generator is used to speed up the nuclei of hydrogen and other small nuclear particles by electrostatic attraction and repulsion. The result is a beam of particles traveling about one-tenth the speed of light.
Focused on a target, the effect of this bombardment reveals clues as to the structure and processes which occur inside the atom.
The generator, which weighs five tons, was designed to develop a maximum operating potential of three million volts and a power output of 75 watts. It was recently operated at more than two million volts, the highest value yet reached. A small change soon to be made will enable it to run at maximum power.
Pressure insulation is the principle reason why the Van de Graaf generator can attain such high voltages. To prevent losses caused by sparking, the electrodes are enclosed in a steel tank where the pressure is about 10 times air pressure at sea level.
Medical Lecturer To Speak April 24
The second Clendening lecture on the history and philosophy of medicine will be given by Chauncey D. Leake, vice-president of the University of Texas Medical branch, Galveston.
The talk will be at 11 a.m. Tuesday, April 24, in Strong auditorium. Mr. Lake will speak on new gems from old Egyptian medical papyrus.
Funds for the lectureship were contributed by Mrs. Logan D. Clendening in memory of her husband, Dr. Clendening, who was a member of the staff of the School of Medicine.
The second lecture will be given at 4 p.m. Wednesday, April 25, in the amphitheater on the third floor of the Clinic building at the University of Kansas Medical center in Kansas City.
Dr. Leake will tell of the Hearst medical papyrus at this meeting.
Ornithology Class Takes Field Trip
The courtship behavior of prairie chickens was studied by the ornithology class on an early-morning field trip recently. Ten members of the class and H. B. Tordoff, instructor, left at 6 a.m. for the prairie country in Franklin county, southeast of Ottawa.
Maurice Baker, graduate student, and Richard Frederickson, College senior, accompanied the class.
"We will be out on field trips every Saturday for the rest of the term," said Mr. Tordoff.
Construction of the generator started in 1947. Except for forming the pressure tank, the project was carried out by the staff of the physics department and graduate students.

Students interested in making reservations should call Mary Lou Fischer, education senior, 3510.
States which are already represented are Vermont, Massachusetts Connecticut, Rhode Island, New York, New Jersey, Pennsylvania Maryland, Washington, D.C., Virginia, North Carolina, Florida, Alabama, Ohio, and Indiana.
Illinois, Michigan, Montana, Washington, Oregon, California, Nevada, Oklahoma, Missouri, and Kansas.
Dr. John Ise will represent Kansas
Teacher Register To Be Compiled
A registration of persons qualified to teach, but not actively engaged in the teaching profession, will be conducted Friday and Saturday in the Chamber of Commerce rooms in the WREN building.
Registration will be from 10 a.m to 8 p.m. on Friday and from 10 a.m. to 4 p.m. on Saturday.
Persons who have 60 hours or more of college work, those who now have a teaching certificate, or those who are interested in meeting requirements for certification are urged by the registration officials to register.
The purpose of the listing of qualified personnel is to establish a list of those who may be called upon in the next several years if the teaching shortage becomes acute.
Lawrence Education council officials said there is a shortage both in the high and grade schools, but particularly in primary grades.
City Managers To Hold 4th School
Clarence Ridley, executive director of the International City Managers association, Chicago, will again teach at the City Managers school Wednesday, April 25 through Saturday, April 28 at the University of Kansas.
An attendance of nearly 60 persons from a seven-state area is anticipated. This is the fourth year for the school.
William D. Wolfe, superintendent of schools, Lawrence, is included in the school faculty. Discussion leaders from the K.U. staff will be Dr. Ethan P. Allen, director of the bureau of government research; Allen Crafton, professor of speech; Dr. Hilden Gibson, head of the human relations department; Dr. Edwin O. Stene, professor of political science; and Dean Burton W. Marvin of the William Allen White School of Journalism and Public Information.
The entire morning of the school's second day will be for the now famous "Ridley clinic."
The University Daily Kansan incorrectly reported Monday that Charles Pearson, instructor of journalism, would teach the Reporting I class of Emil L. Telfel, associate professor of journalism.
CORRECTION
Mr. Pearson will teach Mr. Telefel's Editing I class and the Reporting I class formerly taught by Prof Walter Ewert.
UN Forces Make Big Gains
Tokyo (U,P) — United Nations forces launched a general attack in western and central Korea Tuesday. They scored "big gains" behind two tank-infantry killer columns running interference.
The Chinese Communists fled north ahead of the advancing Allied infantrymen all along the front except for the western end of the vital Hwachon reservoir.
One officer said he believed the Reds were withdrawing to another defense line closer to Chorwon, big Red base 17 miles north of the 38th parallel.
At Hwachon the Reds withdrew only to positions north and east of the dam. From there they poured rifle and machinegun fire into two Allied patrols attempting to reach the dam. Both patrols were driven back.
Jump-off of the new U.N. offensive was witnessed by Lt. Gen. James A. Van Fleet, who took over the U.S. Eighth army from Lt. Gen. Matthew B. Ridgway last Saturday.
Van Fleet toured the front lines and said he was "delighted" with the Eighth army's morale and confidence.
Sigma Xi To Hear Dr. Kollmorgen
Members of Sigma Xi, honorary scientific society, will hear Walter M. Kollmorgen, professor of geography, speak at a meeting at 7:30 p.m. Thursday in 210 Blake hall.
Dr. Kollmorgen will speak on the population and settlement changes in Sherman and Thomas counties of western Kansas.
The public is invited to hear the lecture, which will be followed by a business meeting and the election of new members to the society.
KU, KC Engineers To Meet Together
The University chapter and Kansas City section of the American Society of Civil Engineers will hold a joint dinner meeting at 6:30 p.m. today in the Union building. About 60 members from each group are expected.
Following dinner the members of the University chapter will put on a skit entitled "Pinfeathers," a satire on the life of an engineering student at K.U.
Frank Davis, civil engineering department representative on the Engineering Student council, will give a preview of the Engineering Exposition. Thomas Hendricks, another council member, will speak on the social responsibilities of the engineer.
Ernest E. Howard, member of the Kansas City section, will discuss the importance of society membership after graduation. William Gartung, engineering junior, will act as master of ceremonies.
Closing remarks and adjournment will be made by J. Q. A. Greene, president of the Kansas City section.
The current issue of the Midwest Sociological society's quarterly journal, The Midwest Sociologist, accries two articles written by University faculty members.
KU Sociologists Write For Journal
E. Gordon Ericksen, assistant professor of sociology, has written an article called "Human Ecology and the Superhighway with Particular Reference to Los Angeles." E. Jackson Baur, associate professor of sociology, wrote an article titled "Differences Between Voters and Non-Voters."
Davis To Discuss MacArthur
R. M. Davis, professor of law,
will speak to the Young Democrats
on the MacArthur dismissal at 8
p.m. today in 106 Green hall.
WORLD WIDE NEWS
GI's To Lose Insurance
Washington (U.P.)-About 10 million World War II veterans will lose the right to take out new government life insurance policies when resident Truman signs the free GI insurance bill.
The bill will provide $10,000 worth of free insurance for servicemen while they are on active duty, and for 120 days after they leave service.
The measure also will cut off all future rights to national service life insurance for veterans who let their World War II insurance policies expire.
Warns Against Enlarging War
Chicago (U.P.) — Gen. Omar N. Bradley, chairman of the joint chiefs of staff, warned today that any act to enlarge the war in Korea might plunge the nation into World War III.
In apparent answer to some views of Gen. Douglas MacArthur and congressional Republicans, Bradley counselled against the United States rashly serving an ultimatum on the Communist enemy or suggesting the threat of bombardment of the Red China mainland.
Japan Policy Still The Same
Tokyo (U.P.)—Bombassador John Foster Dulles, adviser to the U.S. state department, assured the Japanese today that Gen Douglas MacArthur's occupation policies would be continued.
There will be no change in the J.S. desire to conclude an early peace treaty with the defeated nation, he said.
Orders Check On Policy
Washington (U.P.)-The senate Republican policy committee approved today a resolution ordering a "complete" investigation of United States Far Eastern policy, including the dismissal of Gen. Douglas MacArthur.
MacArthur To Be Televised
Washington (U.P.) — Television viewers as far south as Jacksonville and New Orleans and as far west as Kansas City and Omaha will have front row seats for Gen. Douglas MacArthur's appearance in congress Thursday.
All TV networks, working on a pool basis, will carry the address the length of the coaxial cable. Ceremonies at the Washington monument and a parade along Pennsylvania avenue for MacArthur also will be televised.
RFC Letters Create Problem
Washington (U.P.)—About 800 letters from congressmen to the Reconstruction Finance Corp. gave the senate banking committee the problem today of how to handle them.
Chairman Burnet R. Maybank (D.-S.C.) called the group behind closed doors to try and decide how to look into the file of letters.
Mr. Truman's statement that he found nothing illegal in the letters later dulled interest in them, but the issue was revived when Sen. Charles W. Tobey (R.-N.H.) announced he made recordings of two telephone conversations with the president about RFC matters and the letters.
Other congressional developments:
Un-American—The Communismin-Hollywood investigation reached into the radio industry as the house un-American activities committee called radio writer Sam Moore, film actress Ann Revere, and screenwriter Harold Buchman to testify.
McArthur—Senate Democrats pledged cooperation with Republicans in an investigation of far east extremists by the filing of Gen. MacArthur.
Crime—The senate crime committee studied the American Bar association's recommendation to abandon its sensational hearings and turn itself into a "steering committee" working for passage of formal crime-curbing legislation.
Typrists' tuition—Sen. Harry F. Byrd (D.-Va.) announced that the air force has agreed to stop paying—at least temporarily—tuition fees to train typrists and stenographers on the federal payroll.
Calls Report Whitewashed
Topeka (U.P.)—Mrs. Eumice Hyeo who precipitated the calling of the Shawne county grand jury which reported Monday, today said she planned to lead a movement to call a second grand jury.
Mrs. Hyre, who asked that the original panel be called to investigate "irregularities" in the state insurance department, called Monday's report by the jury a "white-wash." Monday's report of the panel made no mention of the alleged irregularities.
Sub Lost With 75 Crew
Upper Mississippi Highest Yet
Planes, helicopters, at least five destroyers and other warships sped to the scene south of the Isle of Wight, where the submarine had been scheduled to surface at 1:30 a.m.
Portsmouth, England (U.P.) — The 1,620-ton British submarine Affray failed to surface today after a test dive off the English south coast and the admiralty said it might have sunk with its crew of 75.
Winona, Minn. (U.P.)-The Mississippi river surged to the highest level ever recorded here and engineers warned today that most of the city might be under water by Thursday.
Hundreds of volunteers manned shovels and bulldozers throughout the night to build up a 1,300-foot levee as the river rose toward the 18-foot level.
Albanians Battle Reds
Rome (U.P.)—More than 6,000 tough anti-Russian guerrillas are battling government forces in the mountainous northern area of Red Albania, newly arrived refugees said today.
They said the guerrillas have openly defied from 6,000 to 10,000 Russian police and military experts rushed to the tiny Soviet satellite nation last month to squash anti-Communist uprisings.
Except for the guerrilla camp, the civil revolts have been crushed, the refugees said. There was no hope now, they said, that Premier Enver Hoxha would bolt, like Marshal Tito of Yugoslavia, from the Soviet camp.
The removal of MacArthur surprised the Communists as much as it did everybody else. For about three days they said nothing, because their dilemma was that they couldn't praise MacArthur. He wants to carry all-out war to them. Nor could they praise Mr. Truman, because he ordered the troops in against them.
Truman Move Baffled Reds
The Communist finally put their propaganda on a military basis. They said the removal of MacArthur made certain a Red victory in Korea. Then they were silent until yesterday when they came forward with their peace plan.
USSR May Open Peace Talks
Lake Success, N.Y. (U.P.)—Russia may bring international Communism's renewed offensive for peace in the Far East before the United Nations Security council today.
Chief Soviet delegate Jacob A. Malik, may bring up the North Korean peace offer which was broadcast Sunday and Monday by the Pyongyang radio and received at the U.N. Monday. There was no advance inking of Malik's intentions.
Russian Production Is Up
Moscow (U.P.)—Russia announced today that production has soared 73 per cent above the 1940 level with completion of the first five-year plan since World War II.
A 30-page government report said the fourth five-year plan since the system was started in 1923 had been fulfilled in four years and three months. However, no actual production figures were given.
The report said war-ravaged industries had been completely rehabilitated. Production in coal and oil fields ruined under German occupation has exceeded the pre-war level, the report sald.
