Science

Science points act as both a currency and a bonus multiplier.
 * Some buildings can be purchased with Science.
 * Every Science point counts as a 1% bonus to the coins gained per hex during a run, and the coins generated automatically in the player's districts.
 * If you are eligible to progress to the next era, but choose to remain in the current era for another run or two (so that you have far surpassed the goals for that era), the amount of science points you gain (when you do eventually advance) will be substantially higher.
