The Biggest of Puzzles Brought Down to Size
- silentOpen 18y agoInteresting if not slightly fluffy article. Unfortunately, the author decided to use calories as a unit of energy in one of the examples to compare gasoline energy content and human energy consumption. While the numbers are correct, the use of the 'calorie' for a non-dietary energy unit actually equivalent to a kcal, is disappointing. America may learn numerical literacy but it seems unlikely they'll be able to apply it to many problems without a system of units that doesn't require knowledge of arbitrary conversion ratios or ambiguous magnitudes.
