изобретател

Джак Килби (8 ноември 1923 г. – 20 юни 2005 г.) В нашия свят, ако има изобретение, което се е променило не в определена област, а в целия свят и в цялата индустриална система, това е микрочипът с интегрална схема, изобретен от Джак.

OnSeptember12,1958,thiswasthebeginningofagreatmomentwhenTexasInstrumentsengineer'JackKilby'inventedtheworld'sfirstintegratedcircuitICmicrochip.Thisdeviceopenedthepreludetotheelectronicrevolutionofthetwentiethcenturyandatthesametimeannouncedtheadventofthedigitalage.

През 2000 г. той спечели Нобеловата награда по физика. Това е Нобелова награда по физика, която закъсня с четиридесет и две години. Тази чест, тъй като колкото по-дълъг е интервалът между наградите, толкова по-видни са тези постижения.
