I lived in Germany for the latter half of the nineties. On August 11th, 1999, parts of Germany were in the path of a total eclipse of the sun. Freiburg—the town where I was living—wasn’t in the path, so Jessica and I travelled north with some friends to Karlsruhe.

The weather wasn’t great. There was quite a bit of cloud coverage, but at the moment of totality, the clouds had thinned out enough for us to experience the incredible sight of a black sun.

(The experience was only slightly marred by the nearby idiot who took a picture with the flash on right before totality. Had my eyesight not adjusted in time, he would still be carrying that camera around with him in an anatomically uncomfortable place.)

Eighteen years and eleven days later, Jessica and I climbed up a hill to see our second total eclipse of the sun. The hill is in Sun Valley, Idaho.

Travelling thousands of miles just to witness something that lasts for a minute might seem disproportionate, but if you’ve ever been in the path of totality, you’ll know what an awe-inspiring sight it is (if you’ve only seen a partial eclipse, trust me—there’s no comparison). There’s a primitive part of your brain screaming at you that something is horribly, horribly wrong with the world, while another part of your brain is simply stunned and amazed. Then there’s the logical part of your brain which is trying to grasp the incredible good fortune of this cosmic coincidence—that the sun is 400 times bigger than the moon and also happens to be 400 times the distance away.

This time viewing conditions were ideal. Not a cloud in the sky. It was beautiful. We even got a diamond ring.

I like to think I can be fairly articulate, but at the moment of totality all I could say was “Oh! Wow! Oh! Holy shit! Woah!”

Our two eclipses were separated by eighteen years, but they’re connected. The Saros 145 cycle has been repeating since 1639 and will continue until 3009, although the number of total eclipses only runs from 1927 to 2648.

Eighteen years and twelve days ago, we saw the eclipse in Germany. Yesterday we saw the eclipse in Idaho. In eighteen years and ten days time, we plan to be in Japan or China.

Tuesday evening saw the inaugural Connections event at 68 Middle Street, home to Clearleft. It was a rousing success—much fun was had by all.

There was a great turn-out. Normally I’d expect a fairly significant no-show rate for a free event (they’re often oversubscribed to account for this very reason), but I was amazed how many people braved the dreadful weather to come along. We greeted them all with free beer, courtesy of Clearleft.

The talks had a nice yin and yang quality to them. Honor talked about darkness. Justin talked about light. More specifically, Honor talked about dark matter and Justin talked about Solarpunk.

Honor made plentiful use of sound during her presentation. Or rather, plentiful use of electromagnetic signals converted into sound: asteroseismology from the sun; transient luminous events in the Earth’s upper atmosphere; the hailstorm as Cassini pirouettes through Saturn’s rings; subatomic particle collisions sonified. They all combined to eerie effect.

Justin’s talk was more down to Earth, despite sounding like a near-future science-fiction scenario: individuals and communities harnessing the power of the photovoltaic solar panel to achieve energy-independence.

There was a beer break between the talks and we had a joint discussion afterwards, with questions from the audience. I was leading the discussion, and to a certain extent, I played devil’s advocate to Justin’s ideas, countering his solar energy enthusiasm with nuclear energy enthusiasm—I’m on Team Thorium. (Actually, I wasn’t really playing devil’s advocate. I genuinely believe that nuclear energy is the cleanest, safest source of energy available to us and that an anti-nuclear environmentalist is a contradiction in terms—but that’s a discussion for another day.)

There was a bittersweet tinge to the evening. The first Connections event was also Honor’s last public speaking engagement in Brighton for a while. She is bidding farewell to Lighthouse Arts and winging her way to a new life in Singapore. We wish her well. We will miss her.

The evening finished with a facetious rhetorical question from the audience for Honor. It was related to the sonification of particle collisions like the ones that produced evidence for “the God particle”, the Higgs boson. “Given that the music produced is so unmusical”, went the question, “does that mean it’s proof that God doesn’t exist?”

We all had a laugh and then we all went to the pub. But I’ve been thinking about that question, and while I don’t have an answer, I do have a connection to make between both of the talks and algorithmically-generated music. Here goes…

Justin talked about the photovoltaic work done at Bell Labs. An uncle of Ray Kurzweil worked at Bell Labs and taught the young Kurzweil the basics of computer science. Soon after, Ray Kurzweil wrote his first computer program, one that analysed works of classical music and then generated its own music. Here it is.
