Be Interested to Be Interesting

It’s funny when people say “you’re lucky you found something that you love doing.”

It reminds me of that thing Picasso supposedly said when some Parisian marveled at his 5-minute napkin drawing: “Sure it took 5 minutes… and forty years.” Quoted very loosely, but hopefully you get the idea. It’s a result of time and effort.

It’s also a strange thing to say (although I do understand what they mean) because it’s not like taking something from a grab-bag and deciding, “Oh yeah this one’s pretty good. I can do this.”

I used to think that way, as a child. I had no idea about the weight of things. There were fun things (like drawing) and horrible, boring things (like math). What depth was there? For a child, why not change your mind weekly: Teacher, Disney Animator, Doctor… What else? Same with subjects in school: all treated basically equally.

It’s only fairly recently that I started to see that maybe all’s not so equal at all. So when someone says “you’re lucky,” I wonder if they really don’t see it. It has nothing to do with luck. It’s just plain wonder. Taking a step back from living for a second, to wonder at it. Isn’t it WEIRD? Isn’t it interesting that you’re this bunch of non-sentient stuff that’s put together with some bits of code and rules and all of it comes together to make this “living” thing? Don’t you want to know more about that?

It’s unlike anything else, to wonder at that. You can say history is important or finances are important, but then it’s arbitrary human stuff. It could go this way or that, and have little effect on nature outside of our silly little planet. (Although we like to pretend otherwise, and superimpose biological feelings generally unique to our species onto the rest of the universe, with phrases like “Love conquers all.”) But there’s something you can learn about that does affect EVERYthing, regardless of planet or size or anything… Is that luck? It’s noticing. Finally noticing.

It’s important that humans have varied communities with members that have different skillsets in order to function, so we can’t possibly all have the same interests. But if you’re really wondering what to do with yourself, why revert to that grab-bag of subjects? Certainly sometimes circumstances dictate how you can proceed, but when you can make a choice, Why not Be Interested? There’s so much more outside of us…

The concept of the project I find useful. Something you do in the present, and can remember doing in the past, and expect to do in the future, in order to create something. A work of art which need not be in the arts per se, but something human worth doing.”

Do you imagine they must have been fools? Do you think you would never make such a mistake? Don’t you be so sure. Really you have no idea. It’s like nothing you’ve ever seen. You may think you are inured, that nothing outside the mind can really interest you anymore, as sophisticated and knowledgeable as you are. But you would be wrong. You are a creature of the sun. The beauty and terror of it seen from so close can empty any mind, thrust anyone into a trance. It’s like seeing the face of God…

2312, Kim Stanley Robinson

We can’t answer questions about ourselves the same way anymore — by just thinking about it philosophically, looking for some metaphysical reason.

Call it reductionist if you must, but it’s beautiful that even weekly we’re ever-closer to answering our deepest questions by looking into our biological, chemical — and deeper still — physical blueprints.

When wondering why we animals do as we do, we can also inquire about what the particles do, and how those activities travel up and down the chain of magnifications to create a whole, and the epiphenomenon we finally witness.

Did you know that quantum effects are observed in macroscopic, biological processes?

Ephemeral vacuum particles induce speed-of-light fluctuations ›

Interesting!

Questions:

  • Is it a big deal? If vacuum is not true emptiness but “filled with continuously appearing and disappearing particle pairs such as electron-positron or quark-antiquark pairs” then doesn’t it make sense that the SOL would fluctuate when traveling through a space/substance that, itself, fluctuates? Like through water vs air? Do I misunderstand?
  • Are the fluctuations large enough to matter (to us, at our scale)?

Things. And Stuff, too.

The re-evaluation of what constitutes “a thing”, or whether “things” as we think of them even exist. Certainly it’s easy to define objects in our macroscopic world — we can call a set of visible parameters “a person” or ” a planet”. But it seems that “things” are vastly more blurry, the smaller the reference scale — the closer you get to the basics of life’s constituents.

If “things” don’t quite hold up, then neither do some traditional ideas about them. Perhaps some of it is “slippery slope” reasoning, but for example: why should something have a static make-up (gender), how can anyone reasonably think that Mercury affects refrigerators or that cats affect luck, and if what we imagine to be “a person” is actually a tree of possibilities spread out over space-time, why do we think we’re able (at this time) to compress all that into a container?

Relative Perspective

Usually, my personal outlook stems either from the all-encompassing bottom-right of the top image, or from somewhere towards the bottom of the bottom image. (!) Meaning, all else is relative to those scales, in both size (obviously) and importance. This practice helps me live.

It’s nice to be human. It’s nice to have a cool brain that’s capable of noticing all of this. (Or, even just this much?) But unfortunately, our species’ culture is — extremely generally — one that encourages a mental scope ranging from something like a centimeter to a few kilometers. (Metaphorically, but maybe literally as well.) Anything outside of this in either direction is deemed irrelevant, or worse, pretentious.

I’ve been incredibly stressed and angryfor the past few weeks… and finally realized, it’s because I allowed something roughly the size of an A4 sheet of paper and with all the longevity of a fly to become — in my mind — as big as the universe.

It’s disgusting. It doesn’t matter. (Read: { I think you’re all fucking mad. }) “Our” priorities are stupid; it’s important to figure out how not to participate.

I’m aware of being idealistic, but it’s really annoying that selling people stuff, handling money, and providing non-enriching entertainment are all so massively rewarded… while searching for / contributing / creating / researching anything remotely transcendent is not only hard to do, but often puts one in a position of struggling to live.

Why did the Greeks seem to have so much more time and respect for the latter? Ha. Ha.

And when you gaze long into an abyss, the abyss also gazes into you.

Either way, it would mean that the Universe is fundamentally nonlocal, in the sense that every bit of the Universe can be connected to any other bit anywhere, instantly. That such connections are possible defies our everyday intuition and represents another extreme solution, but arguably preferable to faster-than-light communication. “Our result gives weight to the idea that quantum correlations somehow arise from outside spacetime, in the sense that no story in space and time can describe them.”

Fascinating. I wish I could take part in that conversation in some real way.

That’d be a pretty good social leveller, come to think of it. So there, James Murdoch. You might well walk around thinking, “Ooh, hooray for me, I’m the chairman and CEO of News Corporation Europe and Asia, not to mention chairman of SKY Italia and STAR TV, the non- executive chairman of British Sky Broadcasting, and a non-executive director of GlaxoSmith-Kline”, but at the end of the day you’re just one of 900 trillion insignificant molecules in an all-encompassing turdiverse. And your glasses are rubbish.

Anyway, the astronomers who made the discovery about Andromeda deserve our awe and respect, because their everyday job consists of dealing with concepts so intense and overwhelming that it’s a wonder their skulls don’t implode through sheer vertigo. Generally speaking, it’s best not to contemplate the full scope of the universe on a day-to-day basis because it makes a mockery of basic chores. It’s Tuesday night and the rubbish van comes first thing Wednesday morning, so you really ought to put the bin bags out, but hey – if our sun were the size of a grain of sand, the stars in our galaxy would fill an Olympic-sized swimming pool, and if our entire galaxy were a grain of sand, the galaxies in our universe would fill several Olympic-sized swimming pools. You and your bin bags. Pfff!

How can I flip channels and enjoy Midsomer Murders once I’ve been reminded of the crushing futility of everything? I can’t even get worked up about the murders in that kind of mood. Yeah, kill him. And her. And them. Sod it. It’s all just atoms in an unfathomable vortex.

{ “Contemplating the scale of the universe makes a mockery of household chores” }

Every. Damned. Day.

But unlike Charlie Brooker — who seems bothered by being so awed by it all that he can’t take out the garbage — this is my favorite thing. This is why I have garbage jenga and don’t give a fuck. This is what makes it all bearable and worthwhile.

And yet, for some things, totally unbearable. The things that deserve to be jenga’d like garbage in the face of all this… and yet are not, because they’ve been made important by organizations whose CEOs don’t read enough science news. Pretentious things. The worst things.

New research supports the huge potential of { Tidal Power }
January 18, 2013

A global group of scientists and engineers, including from the University of Southampton, has published in a special issue journal of the Royal Society in support of tidal power, which has the potential to provide more than 20 per cent of the UK’s electricity demand, they calculate.

Was { just talking about this }. Evidently Britain, at least, is making headway.

…there is a continuum, a connection back all the way to the Big Bang with these self-organizing systems that make the galaxies, stars, and life, and now is producing technology in the same way.

Einstein [May Have Been] Right: Space-Time Is Smooth, Not Foamy

Space-time is smooth rather than foamy, a new study suggests, scoring a possible victory for Einstein over some quantum theorists who came after him.

In his general theory of relativity, Einstein described space-time as fundamentally smooth, warping only under the strain of energy and matter. Some quantum-theory interpretations disagree, however, viewing space-time as being composed of a froth of minute particles that constantly pop into and out of existence.

“If foaminess exists at all, we think it must be at a scale far smaller than the Planck length, indicating that other physics might be involved,” study leader Robert Nemiroff, of Michigan Technological University, said in a statement. (The Planck length is an almost inconceivably short distance, about one trillionth of a trillionth the diameter of a hydrogen atom.)

Interesting. Initially I thought of a sculpture I created a couple of years ago — the { Quantum Chess } set. Figured this would mean the idea is now obsolete, until I got to the part about Planck length. I’ve never really thought about the distinction between space-time foam and quantum foam before, or perhaps hadn’t heard of the former? Learned something.
