Great Discoveries, the first expansion for Newton, adds two different modules to the game: A deck of 30 new action cards. Once you use these cards below your personal board, you can choose on which side you would like to turn it: action symbol or income. Great discovery tiles you can collect on the different action boards that will give you bonuses during the game or victory points for the final scoring. The New Edition of Newton already includes this expansion. —description from the publisher
