Walter H. BrattainDied 13 Oct 1987 at age 85 (born 10 Feb 1902). Walter Houser Brattain was an American physicist who shared (with John Bardeen and William B. Shockley) the Nobel Prize for Physics in 1956 for investigating semiconductors (materials of which transistors are made) and for the development of the transistor. At college, he said, he majored in physics and math because they were the only subjects he was good at. He became a solid physicist with a good understanding of theory, but his strength was in physically constructing experiments. Working with the ideas of Shockley and Bardeen, Brattain's hands built the first transistor. Shortly, the transistor replaced the bulkier vacuum tube for many uses and was the forerunner of microminiature electronic parts. |

MAGIC SQUARE: Calculate A*B-C
The aim is to place the some numbers from the list (4, 5, 13, 14, 15, 23, 30, 31, 39, 97) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A*B-C. The first user who solved this task is Nasrin 24 T.
