Interactive 3D models of how things work, from a beating heart and the Krebs cycle to a balloon that obeys the gas laws.
An interactive 3D heart that beats in time with a circulation model. Watch the conduction system fire, the valves open and shut, and blood move through every chamber.
Launch AppFollow molecules through all eight enzymes of the Krebs cycle inside a 3D mitochondrion. Trace labelled carbons, starve it of oxygen, or poison a step and watch the cycle respond.
Launch AppHeat, chill, squeeze and inflate a balloon inside a bell jar. Watch the gas particles, predict what happens, and graph Boyle's, Charles's, Gay-Lussac's and Avogadro's laws.
