After writing two books about the history of inventions, one thing I've learnt is that while it is the enchantingly sophisticated technologies that get all the hype, it's the cheap technologies that change the world.
在写了两本关于发明历史的书之后，我学到的一件事是，虽然那些迷人而复杂的科技总能引起轰动，但真正改变世界的却是那些廉价的科技。
In my own book about radio I recorded how, on one drive: "I caught up with the news, learnt some 17th-century history, and was startlingly educated by an unpretentious programme on the history of the stethoscope.
在我的关于广播的书中，我记录了一次驾车经历："我及时获取了新闻，了解了一些17世纪的历史，并被一个关于听诊器历史的平实节目惊人地教育了一番。"
