The biomechanics of walking can be modeled using a rimless wheel. Each time a person takes a step, another spoke of the wheel comes in contact with the ground.

Trochoidal Wave Action

Waves in water take the shape of a trochoid—the path drawn by a point on rolling circle. This is because water molecules follow circular orbits. This textbook page illustrates this phenomenon.

Running Without Springs

The biomechanics of running is often modeled as a mass (representing the body) attached to a spring (representing the leg) bouncing along like a pogo stick. However, this poster illustrates that the energy lost at each step is better modeled without springs.

Ecopavers

Ecopaving bricks form a grid that allows grass to grow while simultaneously providing a hard flat surface for vehicles. This reduces water runoff and re-radiation of heat from roads and parking lots reducing the heat island effect.
