Lessons From the Great Wave

A documentary by BBC4 explores views of risk in terms of cultural clues and imagery. It interviews numerous experts to reveal the origins of The Great Wave off Kanagawa print, and shows how it has represented very different things to different people.

Great Wave

The Japanese viewer apparently sees groups of men set together in harmony with nature to achieve success — possibly a spring-time catch of bonito fish for a hard-working crew returning as quickly as possible to a market. The huge, towering wave is not an image of despair but of power and collective effort. Toshio Watanabe, a Japenese Art Historian, explains:

(1:14/10:04) “It’s depicting, basically, speedboats like DHL or FedEx.” […] (9:14/10:04) This is an image of courage and perseverance because the oarsmen have a job to do. “There are so many rowers because they need speed and they are not worried about the waves at all. They are taking it in great stride.”

Dr. David Peat, a Physicist at the Pari Center in Italy (among several others) suggests a very different effect for a viewer from the West. He sees the Great Wave as a moral lesson for an individual, which centers around mortality, anxiety and a fear of the unknown (based on chaos theory):

(5:40/8:25) It’s telling us something about being on the edge of chaos; something about how we live our lives. We have to have regularity and order. But if we have too much then we become dead. So it’s telling us where life lies. It’s telling us something about ourselves. We have to learn how to live on the edge of chaos.

Although it is easy to split the views and categorize them among Far East and Western views, following the BBC’s narrative, it could be split a different way. Those who live in and around water and on small boats may look at the Great Wave as familiar and controllable; while those who spend all their time on land may look at the wave with fear of the unknown — “surf’s up” versus “run”. Which are you?

Majority of US Children Unable to Swim

The BBC reports that drowning is the second leading cause of death among US children under age 14. Results from a study of 2,000 children suggests that leaving swimming education up to parents has significantly increased risk.

Just under 70% of African-American children surveyed said they had no or low ability to swim. Low ability merely meant they were able to splash around in the shallow end. A further 12% said they could swim but had “taught themselves”.

The study found 58% of Hispanic children had no or low swimming ability. For white children, the figure was only 42%.

“It is an epidemic that is almost going unnoticed,” says Sue Anderson, director of programmes and services at USA Swimming.

Ironically, it is said a parent’s own fear of water is the primary reason they do not help their child learn to swim.

“Fear of drowning or fear of injury was really the major variable,” says Prof Carol Irwin, a sociologist from the University of Memphis, who led the study for USA Swimming.

Typically, those children who could not swim also had parents who could not swim.

A secondary reason is related to a history of discrimination and segregation in America. The opportunities for swimming are not always equal.

The BBC compares the issue to the UK where swimming is required (except in Scotland) as part of the education curriculum, but they do not provide UK drowning statistics.

Pacific 8.9 Quake Tsunami Info

Only a short time ago (9:45 pm Pacific) tsunamis caused by a 8.9 Earthquake hit Japan. Another strong earthquake is expected.

Orcas Hunt in Predictable Stealth Mode

Researchers say that Orcas can co-ordinate attacks without using normal communication channels.

“They go into stealth mode – completely silent,” said Dr Deecke [from the University of St Andrews in Scotland]. “This raises the question: how are they communicating?”

It seems that orcas can carry out complex, co-ordinated mammal-hunting trips without “talking to each other” at all.

[…]

Dr Deecke thinks that the orcas might “rehearse” their hunting routines, to learn the position of each group member.

“They tend to be very predictable,” he said. “I often know exactly where they are going to surface.”

Very predictable stealth mode? Funny. I assume he is trying to make a point with the contradiction in what he is describing.

Orca
Haha, missed again
