SimInsights is making simulation tools that enable virtual tinkering in collaboration with your friends. You can tinker with a model of a machine or circuit, then send a link to your friend so he or she can tinker with it. With tinkering comes experience which eventually helps build intuition and insights. Those insights differentiate a great scientist or engineer from a good one. Companies all around the world are tinkering with simulation tools to design better products in less time and with less money. Why shouldn't young people do the same?
