I am passing this request along on behalf of Kevin McCartney, Director of the new Northern Maine Museum of Science. They would like to build and exhibit a "galton quincunx," a device used to drop balls to show a normal bell curve distribution. Do any of you science museum folks have such an exhibit? Would you be willing to share plans? Please respond to me, and I will pass all information to Kevin. Thanks in advance! --Julia Hunter, Manager, Cultural Resources Information Center Maine State Museum, State House Station #83, Augusta, ME 04333-0083 (207) 287-5794 [log in to unmask]
