- What is measurement?
- Numerals vs. numbers
- Measure the indicators not the concepts
- Atomic Clock
- Old atomic clock is only accurate to a few tens of quadrillionths of a second.
- What is the "true concept" of a second? 9,192,631,770 Hz, a natural resonance frequency of cesium, which defines the length of the second in our modern world.
- Systematic error
- Random (human) error
- Can we repeat the measure and find a similar result (measure twice, cut once)?
- Counting Votes
