This new unit can be used in conjunction with any brand of potentiometer requiring 6 M.A. or less measuring circuit current at nominal 1.029 V.D.C. It operates directly from line voltage input of 100 to 135 V.A.C., 50/60 cycles, and provides extremely precise regulation with highly accurate temperature compensation. It can also be used for a bridge circuit power supply with slight degrading of voltage regulation. You'll find West's constant voltage supply exceptionally compact...only 2 1/2" x 2 1/2" x 4 1/2".

[[/advertisement]] Getting into College (Concluded from page 24) further learning by your answers to his questions. Learning becomes even more fun when it is shared by all members of the family. The child who is a natural reader presents no great problems. If your family includes a nonreader you have a special problem, but one which can sometimes be solved by introducing him to books which feed his natural interests. A librarian will help you select books which deal with baseball, with the mechanical world, with birds or animals, and, later on, books on electronics, chemistry, music, or art. Once your child has learned the fun of reading in the field of his special interest, there is a chance that he can be led into an exploration of other fields. No College Is "Best" You may wonder at this point why I have said nothing about marks or test scores. The omission of these two tyrannies is intentional. When learning is in its rightful place, marks and test scores follow learning. Today so much emphasis is placed on the difficulty of winning admission to college and on the importance of tests and marks that all to often marks and tests have become the goals of learning rather than the by-products. When marks and test scores are made the primary target of learning, real learning is lost. The school report cards give you an opportunity to place marks in proper perspective. Instead of asking "What did you get?" try "What have you learned?" It is up to you to de-emphasize the marks and test scores and to help your child focus on reading, writing, and learning. An approach like this as preparation for college helps your child to understand that learning is something he does where he is and that all about him are people and books which will help him later. Under such a program your child will see that his understanding of the world does not depend on whether he is in Boston, or in San Francisco, or in Yankton, but on how much advantage he takes of the opportunities around him. If your child is reared in this manner, neither he nor you will worry about whether he gets into Harprince, Dartyale, or Calford, but only that he gets to a college where he can talk to teachers, 58 THE TECHNOLOGY REVIEW
