The IRSâs audit priorities fall into four areas: 1  Tax return ânon-filers and underreporting of income.â The IRS now estimates that there may be as many as of 8.6 million non-filers. 2  This number is up from about 6 million estimated non-filers just a few years ago.
Jack Kilby, in full Jack St. Clair Kilby, (born Nov. 8, 1923, Jefferson City, Mo., U.S.âdied June 20, 2005, Dallas, Texas), American engineer and one of the inventors of the integrated circuit, a system of interconnected transistors on a single microchip.
It was in a relatively deserted laboratory at TI's brand new Semiconductor Building where Jack Kilby first hit on the idea of the integrated circuit. In July 1958, when most employees left for the traditional two-week vacation period, Kilby -- as a new employee with no vacation -- stayed to man the shop.
