Kingston, Ontario, 1-Jan-1999 -- Eureka Software Inc. (www.eureka.ca) today released version 1.1 of Newton's Aquarium: A Solar System Construction Set for Mac OS. Greater numerical accuracy, collision detection, improved graphics, basic 3-D support and on-line help are just a some of the new improvements in this latest release. Newton's Aquarium is an interactive physics package that helps students visualize and understand Newton's Law of Universal Gravitation. While building and exploring their own solar systems, students are exposed to many of the core concepts in classical physics. Newton's Aquarium was designed for use in high school and college physics courses. Features: * Interactive 3-D n-body simulation * Display of velocity, acceleration and force vectors * Centre of mass and conservation of momentum * Collision detection * Variable G and distance exponent * Real mks units * Cut, copy and paste, export and print * Gravitation Ltd. 4.0 & 5.0 document support * Sample universes, stationery pads and student activities * On-line User's Guide, balloon help and tooltips Requirements: * Mac OS 7.0 or later (8.0 or later recommended) * 2 MB free memory (3 MB or more preferred) * 68020 processor or better (68040 or PowerPC recommended) During the last few weeks, teachers from around the world were invited to test and review Newton's Aquarium. Dr. Hal Hawley, a former physics teacher and K-12 Curriculum Specialist for Montana's Department of Education, had this to say: "The graphical imagery is wonderful. Your software is exciting and appropriate for anyone learning about the basic laws of physics. As a former physics teacher I find your curriculum to be outstanding. What a powerful and informative tool! You are to be commended for designing a first rate instructional program."
