After World War II, Los Alamos was anxious for its own computer. While on a walk along the river during a picnic with their families, Enrico Fermi outlined to L.D.P. King a plan for an analog computer to simulate neutron transport. L.D.P. King built it with materials lying around the Omega Site in Los Alamos Canyon. They used the “FERMIAC” for a couple of years, and it was forgotten, until 1966, when Bengt Carlson found it in his office. The lab drew up some blueprints and it went out on loan to the Smithsonian. It is now on display at LANL’s Bradbury Science Museum. There still are several questions as to how the FERMIAC was used. The FERMIAC is too fragile to handle, so our plan in the summer of 2017 was to build a museum-quality replica, much like the Italians did last year. However, the summer student was leaving before it could be re-constructed. Thus, finding ourselves in a similar situation as Fermi and King, we developed our own one-speed neutron transporter fashioned out of the chassis of a toy monster truck. We describe our “Monster Truck FERMIAC” on an XY problem.

第二次世界大战后，洛斯阿拉莫斯（Los Alamos）急于拥有自己的计算机。在与家人野餐期间在河边漫步时，恩里科·费米（Enrico Fermi）向LDP King概述了模拟计算机以模拟中子传输的计划。LDP King用位于洛斯阿拉莫斯峡谷（Los Alamos Canyon）欧米茄（Omega）场地周围的材料建造了它。他们使用了“ FERMIAC”几年了，直到1966年Bengt Carlson在他的办公室里找到它时，它才被人们遗忘。实验室草拟了一些蓝图，然后借给史密森尼实验室。现在在LANL的布拉德伯里科学博物馆展出。关于如何使用FERMIAC，仍然存在一些问题。FERMIAC太脆弱了，因此我们在2017年夏季的计划是建造博物馆品质的复制品，就像意大利人去年一样。然而，那个暑假的学生在重建之前就离开了。因此，发现自己处于与费米和金类似的境地，我们开发了自己的单速中子运输车，该运输车是用玩具怪物卡车的底盘制成的。我们描述了有关XY问题的“ Monster Truck FERMIAC”。
