Answer: PEDOMETER
Example of device to measure steps taken
Marie asked me the same question a few years ago when we had shared a rainy afternoon under a green awning. We had an entire conversation isolated only on that question. My last name, Angstrom, is outmoded as a scientific measurement. Very few people in the scientific world still use the word, preferring to measure in nanometers, which are equivalent to one millionth of a millimeter. One nanometer equals ten Angstrom. When we had the original conversation, she told me that I was smaller than the nanometer, but that meant that in and of myself, I encompassed the nanometer. The nanometer reads ten Angstrom.
She was also asking how far I've traveled since she last asked. We had talked about building a device to measure steps taken in incredibly small measurements years ago, and we jokingly argued about whether the device should measure in nanometers or Angstrom. She wanted to call it a nanometer, like a speedometer. How many nanometers had it been since I saw Marie?
