The Scientific Way To Cut A Cake

Alex Bellos demonstrates cutting a cake using scientific principles.

Brilliant!

In 1906, Sir Francis Galton proposed a way to cut a round cake so that the exposed inside does not go stale. For some reason, his method of cutting a cake did not catch on. Numberphile explains it to us, which is interesting in a geometric way, but only truly useful for people who have a round cake and find themselves eating it over several days all by themselves. Which is sad. Galton must have been a lonely man. When I bake a cake, there isn’t any at all left by the next day. And if you do eat cake by yourself, here’s a tip: you don’t have to put it in the refrigerator.

Pendulum Rolling Ball Clock

Using simple wood pieces, gears, and wire, Turnvater Janosch invented a completely mechanical pendulum rolling ball clock.

Enjoy!

A homemade mechanical rolling ball clock (english, deutsche Version)

The clock runs for 12 hours, driven by a weight of 2.5 kg sinking approx. 1 meter during that time.

Every minute a marble is lifted up and goes down a marble run with three flipping traps that count marbles for minutes, five-minute-steps and hours.

The timekeeping element is a second-pendulum with a pinwheel escapement.

The clock achieves a drift of less than 1 second per day.

How Falcons Catch Their Prey

How Falcons Catch Their Prey

Scientist Suzanne Amador Kane has discovered that falcons keep their prey locked in the same place on their retinas by attaching cameras onto hunting falcons. The original research was published in The Journal of Experimental Biology.

Amazing footage of falcons hunting crows.

Suzanne Amador Kane, working with falconers across the globe, has discovered that falcons pursue prey by keeping the image of the prey in the same place on their retina during the pursuit as they close in.

This movie shows ground breaking footage capture by movie cameras mounted on hunting falcons filmed by Eddy De Mol and his colleagues Valerie Collet and Francois Lorrain.

What’s Inside Red Wine?

Have you ever wondered what’s inside red wine? Wired takes a look at the ingredients that make red wine look, smell and taste the way it does.

Enjoy!

Oenophiles wax poetic about the look, feel, smell, and taste of red wine. But what’s actually inside the drink? Dozens of complicated molecules from the grape’s juice, seeds, and skin. Oh, and alcohol.
