Pooh Sticks

Just a short post today. I came across this video of the strangest animal behaviour I’ve ever witnessed. The bear, named Claude, can be seen twisting and spinning a large stick with more precision and agility than your average sergeant major. Such complex tool use is rarely seen in the animal kingdom naturally, such as […]

Fact of the Day #2 Pigeons are smarter than most mathematicians. Well, they are if you look at one specific mathematical conundrum called the Monty Hall Problem.

All the water we normally drink – from taps, from bottles, from the garden hose – contains impurities which affect a property of water called tonicity.

This, simultaneously, causes your inner ear bones to dance around like a teenager at a rock concert. In turn, this moshing vibrates tiny hairs in your […]

The Descent of Giraffe

The birth of a new life, for most of us, is a wonderful thing. For the newborn, it is the first glimpse of our bright, brave new world. What adventures have we set in store? What beauty will we see? A multitude of possibilities are ahead. For a baby giraffe, however, birth must be an […]

The Dance of the Starlings

This amazing video by Mark Rigler demonstrates the beautiful complexity that exists throughout the natural world. Like a Bach fugue, patterns emerge and fade, interweave, and are exquisitely modified to form an endless variety of beautiful structures. The end result seems too complicated, too ordered, too apparently designed to have appeared by chance. But, like […]
