The most awful invention is nothing more thana so-called perpetual motion machine.According to the law of conservation ofenergy,there is no such a machine existing in the world.You see,energy neitherproduces nor disappears without foundation; it can only transfer from one formto another or shift from one object to another,and its general quantity is alwayskept changeless during transferring or shifting.Now,everybody knows that sucha machine can not do work without limit while not being supplied with energy froman external source.Unfortunately,there used to be many wishful thinkerswanted to invent perpetual motion machines; among them there is no lack of nominalcitizen scientists who wished that they should have broken the scientificsystem in existence,but more of them were those who wanted take advantage of itto cheat others of money.
最糟糕的发明莫过于所谓的永动机.按照能量守恒定律,世界上根本不可能有这样的机器.能量既不会凭空产生,也不会凭空消灭,它只能从一种形式转化为其他形式,或者从一个物体转移到另一个物体,在转化或转移的过程中,能量的总量不变.现在,人人都知道这种机器不可以连续无限期地作功而不从外部能源吸取能量,不幸的是,曾经有许多痴迷者企图发明永动机,这些人中不乏希望打破现有科学体系的“民间科学家”,更多的则是一些想借机牟取钱财的人.
