Players all begin with a value of zero. Players alternate turns adding a random number of 1–6 to their current value. The first player to reach a value of exactly 100 wins (if adding the random number to a player's total would make the total exceed 100, do not add the random number this turn). When a player's total exactly reaches certain numbers, the total changes. For example, if a player reaches exactly 9, her total becomes 31.

The chemical industry, seeing its livelihood threatened by her action, responded with an equally selective set of arguments, chosen in defense. This may have been a fine way of achieving justice, and perhaps in this instance it was scientifically excusable; b...
