在科幻电影《全面回忆》中,地心隧道列车出现在银幕上,这或许还是电影史上的第一次.其实地心隧道列车并不是什么新奇的想法,早在17世纪,英国科学家胡克就提出过这个设想.1构建物理模型S.Targ在其所著《理论力学简明教程》中涉及到一个有趣的力学问题:“忽略空气阻力和摩擦,试求物体从沿着地球的弦开挖的隧道AB的一端运动到另一端所经过的时间.”[1]设地球半径
In the science fiction movie “Total Memories,” the Geocentric Tunnel trains appear on the screen, which may still be the first movie history.In fact, the geocentric tunnel train is not a novel idea, as early as the 17th century, British scientists Hook Proposed this idea.1 The Physical Model Building S.Targ involved an interesting mechanistic problem in his book “The Concise Theory of Theoretical Mechanics”: “Ignoring air resistance and friction and trying to excise objects from the string along the earth Of the time that has elapsed since the end of tunnel AB has moved to the other end. ”[1] Set the Earth’s radius
