Frederick P. Greenleaf, 17, grand prize winner of the 14th annual Science Talent Search and his apparatus used for the separation of metals by distillation

Chemical Project Wins Prize Awards to winners of Science Talent Search cul­

minates competition among 40 high schoolers from 17 states

A METHOD to isolate rare earth metals -"* more cheaply and more efficiently than is now practiced copped the first prize in the Fourteenth Annual Science Talent Search. Frederick Paul Green-leaf of Allentovvn High School, Allen-town, Pa., developed the method and received the $2800 Westinghouse Grand Scholarship.

Presenting the awards to winners of the Science Talent Search culminated a five-day competition among 40 high school seniors from 17 states. The 40 teen agers, picked from 2575 entries of other students throughout the na­tion, were brought to Washington to take part in the Science Talent Insti­tute and to compete for the scholar­ships provided by the Westinghouse Educational Foundation.

Greenleaf, grand award winner (17 years old and a high school senior) found that an old chemical method of separation, that of distillation, could be more effectively and cheaply used to boil off rare earths one at a time than could other present methods of separating the rare earths. Greenleaf found that the most promising solution was a partially tested electrolytic sepa­ration from pyridine solutions of an­hydrous chlorides yielding such metals as sodium and lithium from their salts.

Runner-up for the top award and re­cipient of a $2000 scholarship was Kathleen Anne Hable, 18, of LoyaL

Wis., who conducted studies in hered­ity.

Eight other finalists received $400 scholarships and the other 30 received scholarships of $100 each. Among the exhibits of interest to the chemical field was the one of W. Stanley Marshall, 17, of Isaac Litton High School, Nash­ville, Tenn. Marshall, a $400 scholar­ship winner, extracted alkaloidal and other principal medicinal components from crude botanical drugs.

A second alternate to a $400 scholar­ship, A. Gary Shilling, of W. W. Ross High School, Fremont, Ohio, exhibited his slow neutron nuclear reactor.

Coal Microscopy, A New Tool for Coal Research was the exhibit of Carol Irene Hawkins, 17, of South Charleston High School, South Charleston, W. Va. Carol was a $100 scholarship winner.

their program is designed to help women's colleges because these insti­tutions are making an indispensable contribution to America by helping to provide a constant supply of educated trained women so important to prac­tically every aspect of our national life today.

In addition to the scholarship pro­gram for women Procter & Gamble also has a general scholarship program un­der way bringing their present scholar­ship fund from the level of $328,000 to more than $650,000 per year. The two programs will provide 200 four-year undergraduate scholarships at 25 to 30 privately endowed colleges and universities and 40 four-year scholar­ships at women's institutions.

Each scholarship, under both the women's college and the general col­lege program, provides for full tuition for four years, an allowance for books and supplies, and an unrestricted addi­tional grant of $500 each year to the institution. Two thirds of the scholar­ships under the general program will be in the area of liberal arts and one third will be technical scholarships.

Women Physical Scientists A r e in Demand

Women trained in the physical sciences are needed and wanted in in­dustry, in medical fields, in government establishments, and education. This is a conclusion reached by a conference of educators and employers on the role of women's colleges in the physical sciences held at Bryn Mawr College in June 1954.

One of the greatest obstacles in the way of educating women in scientific fields has been the persistence of cer­tain outmoded conceptions in the minds of students, of their parents, and even of some employers and educators, according to a report based on the con­ference. Among these are the beliefs that it is not womanly to study science, that there is no cultural value in the study of the physical world in which we live, and that there are no really good opportunities for women in scien­tific fields.

The results of the conference discus­sions may be secured from the depart­ment of physics, Bryn Mawr College, Bryn Mawr, Pa.

gineering work on a high level. Cur­rent demand, for the degree is small, said j . C. Warner, president of Car­negie. Drojpping of the professional degree in rto way affects Carnegie's academic programs leading to the en­gineering degrees of bachelor of science, master of science, and doctor of philosophy.

• Ohio S ta te University's college of engineering is introducing a course on the fundamentals of nuclear engineer­ing during the 1955 spring quarter. This course includes the necessary basic nucleaa: physics and the primary elements of reactor technology. • St . John's Universi ty of N e w Y o r k is erecting .a four-level science-phar­macy building at the university's new suburban caampus in Hillcrest, Queens. The building will include lecture halls seating 240 students, science lecture rooms seating 90, and many small and large laboratories for students in addi­tion to faculty research labs. Faculty and administrative offices and a general science library on the structure's sec­ond floor a re also included in its plans.

• Saint Petee-'s College, beginning with the fall teran, September 1955, will offer a pre-«engineering curriculum in conjunction with the college of engi­neering, Unriversity of Detroit. Stu­dents matriculating in this program will take a two-y^ear pre-engineering curric­ulum at S^int Peter's College and then transfer to the University of De­troit college of engineering for their junior, pre-senior, and senior years. The engineering program is a five-year program wtxether taken entirely at De­troit or taken at Saint Peter's College and Detroit-• Pratt Insfr-ltute School of Engineer­ing will offer major sequences in chem­istry aiid in industrial engineering. These curriculums are added to those in chemical, electrical, and mechanical engineering which have been regularly offered. • University of Tennessee is including eight classes in different phases of nuclear scie-nce and radioactivity in its July 18 to 29 th education short-course for high school science teachers. Classes will include instruction in atomic and nuclear structure, radioac­tivity detection, tracer techniques, atomic energy, and health physics. Laboratory sessions will help the teach­ers set up classroom demonstrations with radioisotopes made available through a national movement to aid science teaching in the secondary schools. Amplications may be obtained from W. W. Wyatt at the U-T college of education in Knoxville, Tenn.
