世界上第一台通用目的数字计算机诞生了，名叫“电子数字积分计算机”，英文缩写“ENIAC”(埃尼阿克)。黑料网

事实上，ENIAC只是世界上的第二台电子计算机——开创者属于ABC(阿塔纳索夫-贝瑞计算机)——它只是第一台通用电子计算机。

但这丝毫不影响它在历史上的地位，因为它是完全的电子计算机，能够重新编程，解决各种计算问题，使得人类首次以电子速度进行数学计算。

ENIAC的诞生源于二战期间美国军方的需求，目的是给美国陆军的弹道研究实验室(BRL)计算火炮的弹道轨迹。

ENIAC由宾夕法尼亚大学摩尔电气工程学院研制，创造者包括科学家约翰·冯·诺依曼，工程师埃克特、莫希利、戈尔斯坦，以及华人科学家朱传榘，其中埃克特是总工程师，当时年仅25岁。

ENIAC诞生后，每秒能进行约5000次加法或400次乘法计算，是同期设备的1000多倍，更是手工计算的20万倍。

宾夕法尼亚大学工程学院博客提到：“原本用手摇计算器需要12小时的弹道计算，ENIAC只需30秒就能完成。”

除此外，它还被用于氢弹计算、弹道导弹与火箭测算、天气预报实验等多项工作。

当年，ENIAC的运算能力无可匹敌，但是今天，一只普通的电动牙刷，算力都比它强得多。桃图杂志
