聪明人的机器 有史以来,人类就在寻求能够帮助减轻计算量和加快计算速度的设备。直到十九世纪这种设想才有了实现的可能。 法国科学家帕斯卡设计了一台以机械为原理的计算机,这种机器可以做八位数以内的加减法,能自动逢十进一,机器上面有一个窗口,可以看到计算的结果。 德国数学家莱布尼兹改进了帕斯卡的加法机,设计并创造了能做四则运算的手摇计算机,它能进行整数和 Smarter Machines Historically, humans are seeking equipment that can help reduce the amount of computation and speed of computation. It was not until the nineteenth century that this vision had been realized. French scientist Pascal designed a mechanical principle of the computer, the machine can do addition and subtraction within eight digits, automatically every decade, the machine has a window above, you can see the results of the calculation. German mathematician Leibniz improved Pascal’s addition machine, designed and created a hand-cranked computer that can do four operations, which can be integer and
