Physics of Life videos - favorites

Certain of the videos we have produced for Physics of Life stand out as my personal favorites. Here are a few, which I update from time to time, so come back often.

The paradoxical locomotion of the water strider

Water striders inhabit the interface between air and water. When they move about, are they swimming or walking? The answer will surprise you

Angie and the vortex

Swimming, flying and paddling all rely on a common mechanism for generating thrust - imparting momentum to a relatively stationary fluid vortex.

Life at low Reynolds number

The strange viscous world of little things that live in ponds.

The click of the click beetle

The surprising physics behind the click of the click beetle. Filmed on location in Namibia.

Leaf shape and leaf temperature

How plants use leaf shape to control the temperature of their leaves.

Keeping a dry leaf

How leaves use a trick of surface tension to keep dry even in pouring rain.

Why don't trees fall down?

Why dont trees fall down? The answer will surprise you.

Succulents and flow

What are succulent plants doing with those spines. We use fluorescein dye to follow how spines affect flow of air around the plant.

The frill is gone

How a basic understanding of fluid flow can tell us something about the biology of long-extinct animals, like the function of the frills of Triceratops.

The Reynolds number and flow

A demonstration of flows around simple shapes and the different Reynolds number regimes.

Optimum walking speed

Physics of Life goes to Namibia to answer a basic question: How fast should animals walk? We use the physics of pendulums to give an answer.
