Update

It has been a while since I have posted on the blog.  This is mainly because I have been busy. The manuscript of A New Map of Wonders is just about done, and the book will be published in 2017.

Here are two among many passing wonders from the last few weeks. There is no particular connection between them apart from the fact that they both expand our sense of reality.

• Plants may ‘see’ underground by channelling light to their roots. Their stems may act like a fibre-optic cables, conducting light down to receptors in the roots known as phytochromes. These may trigger the production of a protein which promotes healthy root growth.

• Weather systems have been observed on an exoplanet for the first time. Massive storms move across the surface of HAT-P-7b, a thousand light years away. The clouds in its atmosphere are likely made of corundum, the mineral which forms rubies and sapphires.

Not a human move

[AlphaGo] doesn’t perceive the world or move within it, and the totality of its behaviour is manifest through the moves it makes on the Go board. Nevertheless, the intentional stance is sometimes useful to describe its behaviour.

...Commentating on the match, the European Go champion Fan Hui remarked: ‘It’s not a human move. I’ve never seen a human play this move. So beautiful.’ According to AlphaGo’s own estimate, there was a one-in-10,000 chance that a human would have used the same tactic, and it went against centuries of received wisdom. Yet this move was pivotal in giving it victory.

"Dance all night on the shore of another world"

One legend of the Yurok people says that, far out in the Pacific Ocean but not farther than a canoe can paddle, the rim of the sky makes waves by beating on the surface of the water. On every twelfth upswing, the sky moves a little more slowly, so that a skilled navigator has enough time to slip beneath its rim, reach the outer ocean, and dance all night on the shore of another world.

First sight

When people received the digital images from the Hubble telescope, those first few eyes who are getting it on their screens —  I guess it has to be something very similar to that. When I look inside our own anatomy at the time where nobody knows if we even exist it’s the same as looking at dimensions that we never imagined we would ever see because we didn’t know they existed.

Where we got our music

After about half an hour, the wind began to funnel down from the high southern pass, gaining force with each passing moment. A Venturi effect caused the gusts passing upstream through the narrow gorge to compress into a vigorous breeze that swept past our crouched bodies, the combined temperature and windchill now making us decidedly uncomfortable. Then it happened. Sounds that seemed to come from a giant pipe organ suddenly engulfed us. The effect wasn't a chord exactly, but rather a combination of tones, sighs, and midrange groans that played off each other, sometimes setting strange beats into resonance as they nearly matched one another in pitch. At the same time they created complex harmonic overtones, augmented by reverberations coming off the lake and the surrounding mountains. At those moments the tone clusters, becoming quite loud, grew strangely dissonant and overwhelmed every other sensation... 

[Our guide Angus Wilson, a Nez Perce Indian] took us a cluster of different length reeds that had been broken off by the force of wind and weather over the course of seasons. As the air flowed past the reeds, those with open holes at the top were excited into oscillation, which created a great sound -- a cross between a church organ and colossal pan flute... 

Seeing recognition in our faces, Angus then took a knife from the sheath at his belt and...selected and cut a length of reed from the patch, bored some holes and a notch into it and began to play...[Then] he turned to us and, in a measured voice, said: "Now you know where we got our music. And that's where you got yours, too."

Behemoth

So much human sacrifice and environmental devastation have gone to create a false heaven.

The line between night and day

The Station goes around the world in an hour and a half, which means it flies through fifty minutes of day, followed by fifty minutes of night, endlessly repeating. This means that during a seven-hour spacewalk, you may see four sunrises and sunsets. I remember holding onto a handrail on the outside of the Station, which was flying silently up the Atlantic, from south to north, and as we moved toward Europe I could see the terminator—the line between night and day—rolling up over the horizon ahead of us. The white sun sank quickly behind us in a showy flurry of orange, pink, and red horizon bands, and then we were suddenly in twilight, floating into the dark half of the world. The terminator flicked over us, and, in the deeper darkness ahead and below us, I could see a huge lit-up city, glued to the curved Earth, sliding up over the rim of the world to meet me. I could see the structure of the city, with its glowing heart, its network of roads and its halo of suburban lights fading into the dark countryside. The city was Cairo, looking beautiful and radiant. Down there, millions of people were trying to make a living, find or keep a job, provide for themselves and their families, and worrying about the future. I could cover all of them with one outstretched hand. Cairo slid under and then behind me, and more cities rolled into view over the horizon, all tacked to the outside curve of the planet surface, and all seemingly moving toward us, rather than us toward them.
