What began as esoteric explorations of the workings of the physical world – the nature of electromagnetism and the atomic structure of matter, for example – became, in the hands of inventors and innovators, telecommunications, new drugs, medical imaging and devices, nuclear power, the computer chip, and the Internet. There are now more connected mobile devices than there are people on the planet.
一开始，它们只是对物理世界运转方式的深奥探险——电磁学的性质和物质的原子结构等——如今，再发明家和创新者手中，它们变成了通信、新药物、医学造影和设备、核电、计算机芯片和互联网。如今，连上互联网的移动设备数量比地球人口还要多。
