A Thermometer In A Nanotube

Stone Rhino writes: "Yet another marvel has been created in the quest to create minature machines: a thermometer of liquid gallium within a carbon nanotube. The New York Times has an article on this. The thermometer is 10 microns long and measures temperatures from 120-950 degrees farenheit. Of course, the part I find most impractical about it is the fact that you need a scanning electron microscope to read it."

    The inventors of the transistor would have predicted it. The transistor was quite explicitly intended as a replacement for bulky vacuum tubes with inconvenient power requirements, and that's how we are using them.
