Cascade in space

On a whim, I picked up this book I didn't read even half way through. The Mathematics of Juggling, I found, is actually very readable and interesting book. In the former half of the book, the author goes on in depth about siteswap theorems and proofs, which is kind of boring. But, the latter half is a wealth of surprising and interesting topics.

Here's a picture of some relatively new solutions to so-called n-body problem. Celestial objects like suns obey a simple newtonic gravitational rule, however, solving such a system has long been known quite a tough problem to solve. Only two solutions were known until recently. Both solutions were found in 18th century.

In 1993, some guy found that the 3 body cascade is semi-stable. After his founding, somebody did a numerical analysis and predicted that there might be a combination of 3 suns in a galaxy or in the universe, where the 3 objects are doing the cascade! Amazing...

Sony's aquarium

photo by ken

I found this at the base of the Sony building near Sukiyabashi Crossing in Ginza. This weird notion popped up in my mind that this water tank could be a Sony's state-of-the-art display. I couldn't make out each fish but it seemed sooo real. People were gazing into it. Nobody gazes at fake fish? Nah, if it had been fake fish displayed on a device, it makes perfect sense to me that people can't take their eyes off from it. Taking a glance at a distance and hurrying, I didn't have time to check it out.

I googled it, and found that it was a real tank. The fact that I needed to google to be sure is something. Sony could have done it. Actually, they show super high resolution displays inside the building in which you can see every detail of a fish. Gotta check that out.

I took this photo with my cellphone. Not bad.

Hot summer day

My daughter was quite happy playing in a tiny pool we set on a balcony. It was a nice summer day.

Matsuri

There was an anual festival near my house. Surprised to see so many locals gather on a hot and humid summer evening, selling foods and drinks, providing games for kids. Where the hell do they come from? I thought my town is a new urban highly populated are where nobody knows neighbours. Local community is still alive, not that thriving, though.

street performance

On the way back to the office, I saw this street performance near a TV broadcaster in Shiodome area. Wish that had been a juggling act. The performance wans't that bad, though.

You need to have a license to perform in the street in Tokyo. Some peformers find it completely nonsense. I have heard foreign jugglers complaining about it.
