Stop Sign Mistake Proofing

This is a pretty cool example of using technology to prevent problems. The video shows a system that cascades a sheet of water and displays a stop sign directly in the path of trucks ready to crash into a tunnel (because the truck is too tall).

The driver had ignored several less obvious signals that they were headed for danger. This is an application of one of my favorite management (and industrial engineering) concepts: mistake proofing. As I have stated before, often it is really mistake making more difficult rather than mistake proofing. This truck driver ignored the first several warnings and actually could have ignored this one. This system doesn’t physically prevent the error (the options to do this I can think of would be impractical) but this does prevent the errors in any reasonable case it seems to me.

It does seem the process could be improved a big by doing the cool shower stop sign when the truck still has time to turn off without a huge delay. From the video it seems the truck progressed to a point where getting it out of the way created a major traffic backup.

Parrots Given “Names” by Their Parents and Use Them Throughout Their Lives

Parrots learn their ‘names’ from their parents

Parrots, which have long amused us for their ability to imitate our vocal patterns, actually learn to caw their “names” from their parents, says a new Cornell study. The research offers the first evidence that parrots learn their unique signature calls from their parents and shows that vocal signaling in wild parrots is a socially acquired rather than a genetically wired trait.

Previous research had shown that all wild parrots use unique “contact calls” that not only distinguish each bird individually, but also communicate their gender, and the mate and larger group they belong to.

“Parrots can have extremely long periods [leading up] to independence, and this is thought to be related to their large brains,” explained Berg. The same goes for primates, he said, with humans in particular being “off the charts” when it comes to a lengthy stage of child dependence.

More research is required, to better understand the evolution of and interaction between these physical and behavioral traits, he said. “We still don’t have good explanations of how these behaviors help wild individuals survive and reproduce in nature,” he said.

The paper offers some possible explanations: Perhaps the parrots’ far-ranging journeys to “communal foraging sights” are what impress upon each parent the need to have their fledglings’ names sorted out — not unlike human parents’ need to call for their children by name at a crowded fair.

I enjoy learning more fun and cool stuff about the animals we share the world with. They are quite an interesting bunch of creatures.

Friday Fun: Gibbon Plays with Tiger Cubs

While this gibbon appears to be playing with the tiger cubs I am not sure the tigers see it as play.

Capuchin Monkeys Don’t Like Being Paid Less

Quite a fun video. Frans de Waal shows us a task he gave Capuchin monkeys to see if they responded to a sense of fairness. See the rest of the talk.

Frans de Waal is a Dutch primatologist and ethologist. He is the Charles Howard Candler professor of Primate Behavior in the Emory University psychology department in Atlanta, Georgia. His research centers on primate social behavior, including conflict resolution, cooperation, inequity aversion, and food-sharing.

New Blog with Simple Demonstrations and Scientific Explanations

Try this at home is a new blog by Dr Mark Lorch, a chemistry lecturer at the University of Hull, with instructions for the citizen scientist. This example shows how to move a can with a ballon without touching the can.

The posts include instructions on how to do these simple demonstrations and a nice explanation on the scientific reason for what is going on:

Rubbing the balloon on your hair charges it up with static electricity which makes the balloon negatively charged. When you put the balloon near the can it pushes electrons (which are also negatively charged) to the other side of the can. This makes the side which is nearest the balloon positively charged. Positive charges are attracted to negative charges so the can moves towards the balloon.

It is quite a nice site (especially if you have kids interested in science or are a kid interested in science – no matter how old you are), add it to your RSS reader. Here are some more science blogs you may enjoy.
