Java via CheerpJ:
We've partnered with Leaning Technologies to allow our Java sims to run in a browser.
This sim is not compatible with iPads.
Java Version:
Supports offline use and offers improved performance.
Description
Did you ever imagine that you can use light to move a microscopic plastic bead? Explore the forces on the bead or slow time to see the interaction with the laser's electric field. Use the optical tweezers to manipulate a single strand of DNA and explore the physics of tiny molecular motors. Can you get the DNA completely straight or stop the molecular motor?
