Contemplations – Now

An appetizer:

I have approximate answers and possible beliefs and different degrees of certainty about different things. But I'm not absolutely sure of anything, and there are many things I don't know anything about, such as whether it means anything to ask why we're here, and what the question might mean. I might think about it a little bit; if I can't figure it out, then I go onto something else. But I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose, which is the way it really is, as far as I can tell—possibly. It doesn't frighten me.

Is The Great Wave off Kanagawa a realistic depiction?

The Great Wave off Kanagawa, a well-known woodblock print by Katsushika Hokusai, was first published sometime around 1830. The first print in his series Thirty-six Views of Mount Fuji, it depicts a giant wave breaking over three fishing boats off the coast near the town of Kanagawa.

Recently, a team of researchers at the Universities of Oxford and Edinburgh have been studying how these unexpected so-called "freak" or "rogue" waves can form. They have discovered that, under the right conditions, two sets of smaller waves intersecting at 120 degrees can result in these gigantic waves forming. Running tests in their wave pool, they even created a rogue wave very similar to Hokusai's Great Wave.

Like many people, I have been enjoying Hokusai's woodblock print for most of my life. But I had always presumed it was a highly stylized interpretation. How amazing it is to now learn that it is likely a realistic rendition of an actual, if incredible. natural phenomenon! My appreciation of the print has deepened.

From an article by Daniel Oberhaus in Motherboard, Jan 22 2019:

On New Year's day, 1995, the Draupner oil rig off the coast of Norway was experiencing some rough weather. According to a wave log kept at the station, the rig was pounded by 40-foot waves for most of the day, but shortly after 3 PM a single 80-foot wave appeared out of nowhere and slammed into the rig at 45 miles per hour.

Why forgetting may make your mind more efficient

Fascinating article about what recent research is revealing about the way the brain processes information.

Forgetfulness is not necessarily a sign of a faulty memory. "In fact," Wimber says, "it's been shown over and over in computational models and also in animal work that an intelligent memory system needs forgetting."


Forgetting is essential, some researchers now argue, because the biological goal of the brain’s memory apparatus is not preserving information, but rather helping the brain make sound decisions.
