Measuring Distance
The ancient Romans certainly had a hand––and foot––in the way we measure distance today, but modern technology has advanced measuring techniques considerably. Scientists have used nanotechnology to make the study of even minuscule distances more tangible. Readers discover this information and much more through text and illustrations as they learn about the concepts involved and the tools used to measure distance.
