Heat has made civilization possible. With heat, man could melt metals. As man learned to use metals and fuels, industries grew. As a result, engines were invented. These are machines that change heat energy into mechanical energy. Engines can do the work of many men. Without engines industrial civilization is impossible.
Yet when the first engines were built in the 17th century, men were still wondering about the nature of heat. “What is it?” they asked. Not until the early years of the 19th century did they find the right answer.

参考翻译:
热能使文明变得可能.利用它,人类可以融化金属.由于人类学会了使用金属和燃料,工业化发展起来了.结果,发明了引擎.这些就是把热能转化为机械能的机器.引擎可以做很多人才完成的工作.没有它,工业文明是不可能的.然而当十七世纪第一个引擎制成,人们仍然对它的本性存在很疑惑.热能是什么?直到十九世纪初期,才得到正确答案.
