Cosmic Exhilaration and Anxiety

I don't remember a lot from my childhood. Perhaps not a lot has happened then or maybe I choose not to remember. Many of us don't have full recollections, only memories of memories; it is how the mind forms and matures. One of the few memories in sight and sound I do retain is of Carl Sagan on his "Ship of the Imagination" exploring a starry space to the sounds of the opening theme of Cosmos. I did not understand much, perhaps nothing at all, but I do remember a sense of wonder, sincerity and a subtle urgent importance.

Years later, I have re-watched, or perhaps watched for the first time, the entire series, this time as an adult. Watching it has touched me deeply, perhaps especially with the half buried memories of it and with understanding and a framing of many contexts I could not do earlier (it is, after all, dubbed "A Personal Voyage"). Each time I play the opening theme in my mind I can still sense that feeling of wonder that was there, a special kind of innocence I strove to preserve, not always successfully.

I have been in the US these past few weeks as part of an assignment from work and so was fortunate enough to watch live the newly made Cosmos, hosted by Neil deGrasse Tyson. It will take decades to see how the present series affects the children and teenagers growing with it today. The times and the generations have changed, and I cannot say if the medium and the way the message was chosen to be delivered are the best for the current audience (I'll need to ask my nephews). But as part of the 'older' generation, who can't really avoid the comparison (the first episode in particular, it seemed, carries with in it more than a subtle homage for Sagan and the original series) I think it was very well done and look forward for the next episodes. Tyson is perfect for the job and I think Sagan would have been proud.

Funny enough though, as eagerly as I was waiting for Cosmos to air throughout the trip, my day started in church. I am not a christian or any sort of theist for that matter, though, again, my childhood had some affect on me in this matter. Still, I have a strange fascination with churches. Whenever I'm abroad I dedicate a few minutes to sit quietly in a church or a cathedral (New York's St. Patrick's is a favorite of mine), watch the people around and try to absorb the atmosphere. Today (Sunday) I decided to attend an actual service so I put on my least travel weary clothes (one dresses up for Sunday, or so I heard) and went to a church in Brooklyn. I wanted a taste of an actual gospel immersed service, passionate choir, heated sermon and a devout congregation as I imagined it.

And this is also what I had received: friendly, open and welcoming people, thundering music (yes, a joyous noise), a not too long a sermon that was not illogical (for the most part) and a unique experience to take with me and reflect upon. Oh, and also a two hour long panic attack; being in a large hall surrounded by hundreds of people is not easy for an agoraphobic. Yes, I have anxiety (and related depression) issues.

What brought that up, though, is the Scott Stossel article from The Atlantic, that I only fully read today. It is indeed long, but it is also something I could have almost as easily have written myself, with the exception of a few points:
1. I have not been formally diagnosed or treated.
2. I have not taken any medications to deal with it.
3. I don't drink, so that can't numb me.
4. I never met the Kennedys.

How does it all come together? Stossel concludes his story and say that maybe anxiety also has its positive sides, that without it he would have been a different person with a different life. Personally, I think the 'tortured artist' image is far more romanticized than it ought to be, and that there are moments I would do quite a lot to be just a normal, anxiety free (or reduced) kind of a guy. Would I be different? Yes, but isn't that also kind of the point? To try to make yourself better? More free?

As I'm writing this I can still hear the echoes of that opening theme of the original Cosmos. I am tired, tomorrow is my last day in New York, and I already feel the sleep deprivation caused headache. But I am also reassured that I am still on that personal voyage, that I know what I am not (a theist, among other things) though I can appreciate what comes with it and its costs; and that I am still anxious for the road ahead.

I highly recommend the original Cosmos (available on DVDs and probably unofficialy on YouTube)


And the new series (It is Past time to get going again)

A Boltzmann Brain walks into a bar

Have you ever pondered what it would feel like to fall into a black hole? Or wondered, as you observe a black cat turn the same corner twice, whether reality is really all it's cracked up to be? If consciousness involves such high innate latency (around 100ms), how do musicians play so perfectly, without a seeming conscious effort? How much can we really know about the world and ourselves and how much do we have to assume in order to begin to contemplate answering these questions?

An observable Cat {Wikipedia}

These and other questions were discussed at this year's FQXi (The Foundational Questions Institute) conference on the physic of information, held at the impossibly distracting Vieques Island (Puerto Rico). As a layman who's been exposed to a few snippets of it, I can regrettably say I understand very little of what was discussed. Quantum Physics, a known buzzword, now commonly weaved into the vocabulary of charlatans and quacks, is a mystery. As the great Richard Feynman put it, "If you think you understand quantum mechanics, you don't". And yet, it seems to be governing our existence in scales and ways we can barely imagine and produce ridiculously accurate test results.

The title of this post references an issue within physics about the possible emergence, through quantum fluctuations (in which particles seemingly spontaneously come in and out of existence), of something so complex as a brain, with its own unique thought patterns (see Wikipedia here and more advanced stuff here). This is similar, to some extant, to the idea of a room full of monkeys that randomly type the entirety of Hamlet. While extremely unlikely, it's not impossible that over a great length of time (longer than the average queue at the local post office, some say), such an endeavor can be completed. In this year's conference, however, it's been suggested that the underlying physics may not be so supportive of the emanation of floating disembodied brains in the vastness of space after all.

Whether we are brains-in-a-vat, souls trapped inside a frail body, a part of the greater consciousness of the universe or simply our bodies, we need to make sure to include in our basic assumptions, other than that that we can make sense of the world, that we want to. As we live and die we affect one another in more than the observable way. But sometimes, it seems, it would be easier to understand quantum physics than to understand your next door neighbor.

On the music front, and not completely unrelated, I've been listening to quite a bit of Johnny Flynn, whom I mentioned before. Flynn is about to start a big tour encompassing the US, Canada and Europe in support of his latest album, Country Mile (recommended).
