Watching the clock

I've posted before about the phenomenon of dart-thrower's bias; the tendency of humans to notice outliers, and therefore give them more weight in our attention (and memory) than the ordinary background noise with which we are constantly bombarded.  And once we notice a particular outlier, we're more likely to notice it next time -- further reinforcing the effect.

I remember having an experience of this a while back.  On two consecutive work days, I noticed, when I glanced at the clock after finishing breakfast, that it was 6:43.  On the face of it, this wasn't that odd, since my alarm was always set for the same time, and I did more-or-less the same sequence of actions to get ready for work, in more-or-less the same order, every day.  But I did notice it.  And subsequently, every time I glanced at the clock after breakfast and it was 6:43, it registered.  I was less likely to pay any kind of serious attention if it was 6:46 or 6:39, because I'd already primed my brain to be more aware of one particular time.

But if you think this exemplifies dart-thrower's bias, you ain't heard nothin' yet.  There's a guy named Jordan Pearce who posted over at SpiritScience and has had a similar experience, but doesn't chalk it up to a perceptual bias in the human brain...

... he thinks it's evidence we're going to have a "planetary shift of consciousness."

For him, the time was 11:11.  Despite my feeling that 11:11 is simply the most convenient way to get from 11:10 to 11:12, Pearce thinks that this time is deeply meaningful.  Here's what he has to say:

I’ll bet that if I asked publicly how many people saw 11:11 regularly, we’d probably see a huge sea of hands popping up all over the place. Its [sic] pretty common nowadays, there’s something to it, and its about time we decoded it.

In case you answered that you’ve never noticed 11:11, I would remind you that you’re reading a blog about it right now.  Welcome to the beginning of your 11:11 synchronistic voyage.

There was a time only a few years ago when I hadn’t heard a thing about 11:11.  It was brand new to me, until it wasn’t anymore.  Interestingly enough, my 11:11 synchronicities started right around the time when I began learning about a planetary shift of consciousness… The Shift.

Okie-dokie.  But isn't something being "new until it isn't anymore" kind of the usual way things work?  Anyhow, the upshot is, if you notice 11:11, you're heading toward enlightenment, or something.  So yay for you.

Then he throws in a lengthy quote from Uri Geller, who I really wish would go away.  You'd think Geller's popularity would have waned after his conspicuous inability to telekinetically bend spoons on The Tonight Show decades ago, but no, he's still around, and still making grandiose statements about psychic stuff and global consciousness and spiritual ascension.

So Geller doesn't really add anything to Pearce's credibility.  But Pearce goes on, undaunted, and tells us that it all... means something:

11:11 is a wake-up call of sorts, an initiation into the “aha” of realization that something big was going on.  Something that connected everyone.  In truth, the numbers are only a representation of what’s really going on.  A symbol for the connection taking place all over the world.  The numbers aren’t significant, but their meaning.

Well, it would certainly be a wake-up call for me, because if I rolled over in bed and saw the time was 11:11, it would mean that I'd overslept by six hours.  But that's not what he's driving at, of course.  And what sort of meaning does he ascribe to all of this?

When you observe 11:11, you notice some interesting things.  The first thing that I see is that it is a balanced equation.

Actually, it's not an equation at all, given that an equation needs an equals sign somewhere.  But do carry on.

Not only is it two elevens, but two elevens with a : in between.  Two sides of a balanced equation, that equal out at zero.  They have a stable equilibrium were they a mathematical equation.

Yes!  Two elevens with a pair of dots!  And that equals zero!  Except when it equals four:

They also come down to 4.  I feel it like a 4 elements equation, a perfect balancing of a yin and yang energy.  If you know anything about Tarot, you might think of the 4 leaders.  Prince, Princess, Queen, and King/Knight.

I thought that the Tarot cards had a King, Queen, Knight, and Page, but what do I know?  I mean, he's basically making shit up as he goes on, so may as well make this up too, right?  But it gets even better:

Now, the magic about 11:11 is not just that it’s happening to you, but it’s happening everywhere.  11:11 is a global event, it is something that people all over the world, including you right now (because you’re reading this) is experiencing.

Well, I agree that 11:11 is a global event.  In fact, it happens twice a day, no matter what time zone you're in.  That's got to be significant somehow, don't you think?

And he ends with a bang:

You are not alone.  We are all growing and learning different things, and in truth we’re really all learning the same thing.  How to love.  What is love, what does love look like, and what it means to embody Christ.

So 11:11 = 0 = 4 = synchronicity, and therefore Christ?

I mean, this is taking dart-thrower's bias and raising it to the level of performance art.  Sometimes patterns are meaningful, and sometimes they just... aren't.  Imposing some kind of cosmic significance on something that is a random occurrence doesn't make it real.

So anyhow, there you are.  I just glanced at the clock, and it's 5:36, which as times go, is all higgledy-piggledy and unbalanced, and probably points to the fact that I am feeling particularly unenlightened at the moment because I haven't had any coffee yet.  Maybe I'll feel better at 5:55, although by then I'll probably be in the shower.

Maybe I'll see what happens at 6:43.  That's bound to be interesting, right?

Of course right.

Watching the clock

 If I had to pick the scientific law that is the most misunderstood by the general public, it would have to be the Second Law of Thermodynamics.

The First Law of Thermodynamics says that the total quantity of energy and mass in a closed system never changes; it's sometimes stated as, "Mass and energy cannot be destroyed, only transformed."  The Second Law states that in a closed system, the total disorder (entropy) always increases.  As my long-ago thermodynamics professor put it, "The First Law says you can't win; the Second Law says you can't break even."

Hell of a way to run a casino, that.

So far, there doesn't seem to be anything particularly non-intuitive about this.  Even from our day-to-day experience, we can surmise that the amount of stuff seems to remain pretty constant, and that if you leave something without maintenance, it tends to break down sooner or later.  But the interesting (and less obvious) side starts to appear when you ask the question, "If the Second Law says that systems tend toward disorder, how can a system become more orderly?  I can fling a deck of cards and make them more disordered, but if I want I can pick them up and re-order them.  Doesn't that break the Second Law?"

It doesn't, of course, but the reason why is quite subtle, and has some pretty devastating implications.  The solution to the question comes from asking how you accomplish re-ordering a deck of cards.  Well, you use your sensory organs and brain to figure out the correct order, and the muscles in your arms and hands (and legs, depending upon how far you flung them in the first place) to put them back in the correct order.  How did you do all that?  By using energy from your food to power the organs in your body.  And to get the energy out of those food molecules -- especially glucose, our primary fuel -- you broke them to bits and jettisoned the pieces after you were done with them.  (When you break down glucose to extract the energy, a process called cellular respiration, the bits left are carbon dioxide and water.  So the carbon dioxide you exhale is actually broken-down sugar.)

Here's the kicker.  If you were to measure the entropy decrease in the deck of cards, it would be less -- way less -- than the entropy increase in the molecules you chopped up to get the energy to put the cards back in order.  Every time you increase the orderliness of a system, it always (1) requires an input of energy, and (2) increases the disorderliness somewhere else.  We are, in fact, little chaos machines, leaving behind a trail of entropy everywhere we go, and the more we try to fix things, the worse the situation gets.

I've heard people arguing that the Second Law disproves evolution because the evolutionary model claims we're in a system that has become more complex over time, which according to the Second Law is impossible.  It's not; and in fact, that statement betrays a fundamental lack of understanding of what the Second Law means.  The only reason why any increase in order occurs -- be it evolution, or embryonic development, or stacking a deck of cards -- is because there's a constant input of energy, and the decrease in entropy is offset by a bigger increase somewhere else.  The Earth's ecosystems have become more complex in the 4.5 billion year history of life because there's been a continuous influx of energy from the Sun.  If that influx were to stop, things would break down.

Fast.

The reason all this comes up is because of a paper this week in Physical Review X that gives another example of trying to make things better, and making them worse in the process.  This one has to do with the accuracy of clocks -- a huge deal to scientists who are studying the rate of reactions, where the time needs to be measured to phenomenal precision, on the scale of nanoseconds or better.  The problem is, we learn from "Measuring the Thermodynamic Cost of Timekeeping," the more accurate the clock is, the higher the entropy produced by its workings.  So, in effect, you can only measure time in a system to the extent you're willing to screw the system up.

The authors write:

All clocks, in some form or another, use the evolution of nature towards higher entropy states to quantify the passage of time.  Due to the statistical nature of the second law and corresponding entropy flows, fluctuations fundamentally limit the performance of any clock.  This suggests a deep relation between the increase in entropy and the quality of clock ticks...  We show theoretically that the maximum possible accuracy for this classical clock is proportional to the entropy created per tick, similar to the known limit for a weakly coupled quantum clock but with a different proportionality constant.  We measure both the accuracy and the entropy.  Once non-thermal noise is accounted for, we find that there is a linear relation between accuracy and entropy and that the clock operates within an order of magnitude of the theoretical bound.

Study co-author Natalia Ares, of the University of Oxford, summarized their findings succinctly in an article in Science News; "If you want a better clock," she said, "you have to pay for it."

So a little like the Heisenberg Uncertainty Principle, the more you try to push things in a positive direction, the more the universe pushes back in the negative direction.  

Apparently, even if all you want to know is what time it is, you still can't break even.

So that's our somewhat depressing science for the day.  Entropy always wins, no matter what you do.  Maybe I can use this as an excuse for not doing housework.  Hey, if I make things more orderly here, all it does is mess things up elsewhere, so what's the point?

Nah, never mind.  My wife'll never buy it.

When people think of mass extinctions, the one that usually comes to mind first is the Cretaceous-Tertiary Extinction of 66 million years ago, the one that wiped out all the non-avian dinosaurs and a good many species of other types.  It certainly was massive -- current estimates are that it killed between fifty and sixty percent of the species alive at the time -- but it was far from the biggest.

The largest mass extinction ever took place 251 million years ago, and it destroyed over ninety percent of life on Earth, taking out whole taxa and changing the direction of evolution permanently.  But what could cause a disaster on this scale?

In When Life Nearly Died: The Greatest Mass Extinction of All Time, University of Bristol paleontologist Michael Benton describes an event so catastrophic that it beggars the imagination.  Following researchers to outcrops of rock from the time of the extinction, he looks at what was lost -- trilobites, horn corals, sea scorpions, and blastoids (a starfish relative) vanished completely, but no group was without losses.  Even terrestrial vertebrates, who made it through the bottleneck and proceeded to kind of take over, had losses on the order of seventy percent.

He goes through the possible causes for the extinction, along with the evidence for each, along the way painting a terrifying picture of a world that very nearly became uninhabited.  It's a grim but fascinating story, and Benton's expertise and clarity of writing makes it a brilliant read.
