Interactive Physics 1989 ⇒ [ Reliable ]
Students could build incredibly complex contraptions, such as Rube Goldberg machines, using actuators, dampers, motors, and joints.
The brothers founded a company named that same year, basing its entire mission around this single educational tool. At a time when the Macintosh Plus was still a novelty, Interactive Physics arrived as a "general-purpose physics simulator" —offering a 2D environment where anyone could build experiments simply by using a mouse. The idea was as bold as it was simple: instead of memorizing equations, students could actually see velocity, gravity, friction, and collisions unfold on their screens.

Eventually, MSC Software acquired Knowledge Revolution, integrating these pioneering physics simulation concepts into enterprise-level computer-aided engineering (CAE) software. Today, every modern physics simulation tool—from PhET Interactive Simulations to the physics engines powering modern video games like Angry Birds or Kerbal Space Program —owes a conceptual debt to the groundwork laid in 1989.

The core experience was built on a simple drag-and-drop interface that allowed users to:
In 1989, a software program called Interactive Physics transformed science education by turning abstract equations into living simulations. Developed by Knowledge Revolution, this groundbreaking motion lab allowed students and educators to build, experiment, and visualize Newtonian mechanics on a computer screen. By bridging the gap between textbook theory and real-world experimentation, Interactive Physics laid the foundational blueprint for modern educational software and digital physics engines. The Problem: The Abstract Wall of Physics
If you look at the underlying DNA of , you see Interactive Physics. The idea that a user—regardless of coding knowledge—can build a world where objects interact based on physical properties started in that 1989 classroom tool. It democratized simulation, moving it from the hands of scientists into the hands of kids and hobbyists. Why It Still Matters
