180年前的神奇设计！ 这个设计的计算机在150年的时间里一直被认为不可能实现的，直到1991年，一个团队仅使用维多利亚时代的材料建造了这台重达5吨的机器。 这指的是查尔斯·巴贝奇的 2 号差分机。 具体细节如下： 1) 设计于～180年前：查尔斯·巴贝奇确实在 1846 年至 1849 年间设计了 2 号差分机。他之前曾参与设计 1 号差分机，后来又构思了更具雄心的分析机，这台通用计算机。 2) 150 年的时间里一直被认为不可能实现：虽然并非普遍认为“不可能”，但巴贝奇的设计在当时极其复杂，而且由于 19 世纪制造精度和资金的限制，他在制造过程中面临着巨大的挑战。许多人认为，在当时的技术条件下，他的设计是无法实现的。 3) 团队于1991年仅使用维多利亚时代的材料建造了它：伦敦科学博物馆承担了根据巴贝奇原始设计建造差分机2号的项目。他们于1991年完成了计算部分，并于2002年完成了打印机的制造。至关重要的是，他们仅使用了巴贝奇在19世纪所能获得的材料和工程公差，证明了他的设计确实可行。 4) 这台重达5吨的机器运转完美：完成的差分机2号重约5吨，操作时确实按照设计完美运行，自动生成数学表格。 A computer designed in the 1840s was thought impossible for 150 years. When a team built it in 1991 using only Victorian-era materials, the 5-ton machine worked perfectly. This refers to Charles Babbage's Difference Engine No. 2. Here's a breakdown: 1) Designed in the 1840s: Charles Babbage indeed designed the Difference Engine No. 2 between 1846 and 1849. He had previously worked on a Difference Engine No. 1 and later conceived of the more ambitious Analytical Engine, which was a general-purpose computer. 2) Thought impossible for 150 years: While not universally "thought impossible," Babbage's designs were incredibly complex for his time, and he faced significant challenges in getting them built due to the limitations of 19th-century manufacturing precision and funding. Many believed his designs were unbuildable with the technology available. 3) Team built it in 1991 using only Victorian-era materials: The Science Museum in London undertook the project to build the Difference Engine No. 2 from Babbage's original plans. They completed the calculating section in 1991 and the printing apparatus in 2002. Crucially, they used only materials and engineering tolerances that would have been available to Babbage in the 19th century, proving that his designs were indeed feasible. 4)The 5-ton machine worked perfectly: The completed Difference Engine No. 2 weighs about 5 tons and, when operated, does indeed work perfectly as designed, producing mathematical tables automatically.
