Jumping water droplets improve power-plant efficiency
Scalable nanopatterned surfaces designed by MIT researchers could make for more efficient power generation and desalination.
How nutrients spread in a turbulent sea
How nutrients spread in a turbulent sea
A computer simulation shows the way a patch of nutrient material is pulled apart into swirling filaments by turbulence in the water, eventually dissolving away completely.

Shifting sands
Shifting sands
Sand in an hourglass might seem simple and straightforward, but such granular materials are actually tricky to model. Ken Kamrin of MIT MechE has come up with a model that predicts the flow of granular materials under a variety of conditions.
Steel Ball Dropped in a Viscous Fluid
Steel Ball Dropped in a Viscous Fluid
Five steel balls of different sizes are dropped into corn syrup. The balls reach a constant velocity shortly after entering the fluid. The velocity is constrained due to the drag balancing the force of gravity in the fluid. This demonstrates the relationship between the size of the ball and ...
