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.
Little did this group of onlookers know, but Kilbyâs invention, 7/16-by-1/16-inches in size and called an integrated circuit, was about to revolutionize the electronics industry. For almost 50 years after the turn of the 20th century, the electronics industry had been dominated by vacuum tube technology.
