1.6195 .5 5.98.02 . . . Scientific Progress in the past decade has opened to the people- of the world many new fields of endeavor. In our year book we have depicted some of the most unusual and startling de-velopments made by the mind of man. We believe the following photographs portray the greatest contemporary advances. ATOM SMASH ER This 90-ton electrostatic machine is 65 feet high and is designed to build up an electrical field of more than five million volts. BIKINI EXPERIMENT Out of the Bikini lagoon exploded the Baker Day Bomb, A column of water ascended about 5,000 feet high and about 2,000 feet across. This picture is the third in a series of three. SPECTROGRAPH This strange sorting machine segregates gas molecules and their constituent atoms according to their masses. The spectrograph will analyze as little as a thimble full of gas, or a bit of solid substance no larger than a grain of salt, providing it can be vaporized. The device is so sensitive it will detect one part in l00,000 of a substance under observation. BUTADIENE PLANT The manufacture of synthetic rubber was the combined effort of both chemists and chemical engineers. Due to the critical shortage of natural rubber during the war it was imperative to develop a substitute. GRAND COU LEE DAM Grand Coulee, already the owner of an impressive war time record when it generated billions of kilowatt hours of electricity for industry, is ready for another important task - the irrigation of more than a million acres of semi-arid land in south central Washington. SYNCHROTRON The seventy million watt synchrotron, using electrons as projectiles, is a powerful source of x-rays. These machines were created for nuclear research but are bein used in medicine and industr also. 9 TELEVISION ANTENNA Experimental electronic equipment revealed future possibilities for nation- wide distribution of theater television in a demonstration in Schenectady during the year. Microwaves were used to send the program from the WRGB studios to the City's Civic Playhouse. The scenes were fed by way of coaxial cable to a special low-power microwave EM transmitter located on a tower adjacent to the studio. The transmitter output was then beamed by a directional antenna. The sound was also transmitted by means of a radio link. four

ofzewofzd . . . The twentieth century has given to man an ever expanding world. The frontiers of the unexplored regions have been pushed back by the mind of man as it has conquered one by one the various aspects of our physical life. Proof of the progress which has be-en attained is found in the increased comfort, the greater convenience, and the improved standards of living which all of us enjoy. The genius of man is challenged by the realization of the un- limited fields of endeavor which are still before us. Research is beginning to reveal areas which have been shrouded in the dark- ness of ignorance. The surface of the possibilities of human achieve- ment has hardly been scratche-d. New fields of endeavor will con- tinue to unfold as science achieves intriguing wonders which will affect our daily lives. The world of today will seem quite primitive and amateurish in the light of the knowledge which may be gained tomorrow. ln the future our task will be to concentrate our efforts on the new fields of endeavor. The world offers unlimited opportunities if man has the intellectual stamina and the moral fortitude to conquer the new fields of endeavor. That is both the challenge and invitation to the youth of today.

MONTAGE Symbolic of the great variety of an electrical manufacturer's operation are the scenes depicted in this montage at work. The series includes views of a drafting room, giant rotor, huge generator, a research study, search- Iights, a fusing kettle, transmission lines, welders, insulators and Grand Coulee generators, largest in the world. STEEL Molten pig iron is placed in huge vessels, blasts of cold air are blown through this charge. The oxygen in the air combines with the impurities in the metal forming a slag and the result is Bessemer steel. About I2 minutes are required to produce IO tons of steel. odamfs qoufli I marvel at the wonders of This modern day and age, And all that science promises, Upon tomorrow's page. The plane that flies like lightning And the magic mystery Of what can be accomplished with Atomic energy. And yet, I think the world is young, And there are years in store With miracles more wonderful Than anything before. I think that in the universe Posterity will find An answer to the things that now Amaze the human mind. In later years it will be seen, From what the people say That actually in many ways, The world was young today. Dolores Slapkasky five
