The formula for penguin poop.



“Pressures produced when penguins pooh—calculations on avian defaecation
penguins_poo.jpg

Abstract Chinstrap and Adelie penguins generate considerable pressures to propel their faeces away from the edge of the nest. The pressures involved can be approximated if the following parameters are known: (1) distance the faecal material travels before it hits the ground, (2) density and viscosity of the material, and (3) shape, aperture, and height above the ground of the orificium venti. With all of these parameters measured, we calculated that fully grown penguins generate pressures of around 10 kPa (77 mm Hg) to expel watery material and 60 kPa (450 mm Hg) to expel material of higher viscosity similar to that of olive oil. The forces involved, lying well above those known for humans, are high, but do not lead to an energetically wasteful turbulent flow. Whether a bird chooses the direction into which it decides to expel its faeces, and what role the wind plays in this, remain unknown.”

Based on my observations, they aim for a fellow penguin – more points for spraying a clean, white chest.

My favourite snippet from the abstract: “energetically wasteful turbulent flow”… poo poetry if I ever read it.

Global Rich List



How rich are you?

“Every year we gaze enviously at the lists of the richest people in world. (editor’s note: well, not really enviously, more curiously) Wondering what it would be like to have that sort of cash. But where would you sit on one of those lists? Here’s your chance to find out.”

Poke, an interactive company in London, built this site “to challenge people’s perception of their personal wealth… and hopefully raise some money for a good cause.”

a costume of circumstance (I blame the sushi)



“Sweeeetie. Whatever your costume choice,” he gently started, “mouthwash should be part of it.”

Sometimes the truth is funny.

“It could even be your costume. You could say ‘I have really bad breath but it’s disguised in mouthwash.'”

He was the pitcher, I was the catcher.

I never laughed so hard in my life.
