A Tale of Two Kitties

In Dickens’ tale, Madame Defarge is obsessed with vengeance.  The characters in our tale have different obsessions.  One of them is with understanding the code used to knit the fabric of reality.

When they called for weird stories to be submitted for Volume 2 of The Rabbit Hole, the editors suggested science and/or weather and/or entertainment as themes.  While the suggestion was not a requirement, many of the writers who responded did use those themes.  In particular, You’re Not Late has great synergy between weather and an aspect of science other than weather forecasting.  Maybe there are other great synergies; it will take me a while to read all the stories in RH-2.

Modern scientific theories are also stories, of a special kind.  Tho hard to read w/o wrangling equations, they are gloriously predictive and useful.  (U don’t need hard copy to read this post.)  They are also weird.  As the editors remark in the preface:

The stories are weird because life is weird; all these stories do is cross the boundary of our logic and assumptions, fetch a few samples from whatever lies beyond, and bring them back for you to see.  Just as explorers did in ages past, and scientists do today.
 

Back in 1935, the physicist Erwin Schrödinger told a story to illustrate the weirdness of quantum theory.  The story eventually became a celebrated meme, and here is yet another celebration:

Ode to Schrödinger’s Cat
|Schrödinger’s cat
|is both skinny and fat;
|both dead and alive
|(past age seventy five);
|both purring and hissing
|(while measurement’s missing);
|both mewing and yowling
|(while Einstein is howling).
|Schrödinger’s gone,
|but his cat carries on
|with a Cheshire cat grin
|at the pickle we’re in.

cheshire-cat

Hmmm.  Saying that the cat is “both dead and alive” is a common (and admittedly oversimplified) shorthand for the statistical limbo called “superposition of states” in quantum theory.  Here is a closer approximation to what the theory actually says:

If the box is opened now, there is a certain probability P_q (which we can approximate) that the cat will be observed to be dead, along with the complementary probability 1-P_q that the cat will be observed to be alive.  Before the box is opened, it makes no sense to say that the cat is “really” dead or alive.
 

Despite having a deterministic philosophy, Einstein had no qualms about common-sense probabilities:

The cat is really dead or alive, but we don’t know which.  From what we do know, we can compute an approximate probability P_c of the cat being dead now and an approximate probability 1-P_c of the cat being alive now.
 

Greenish-BunnyIs the clash between quantum theory and common sense just something for novice philosophers to argue about?  Nope.  To see why, we don’t need the nasty gadgets in Schrödinger’s story.  We need two kittens from the same litter, in separate boxes some distance apart.  We also — ah — ah — ACHOO!  The cat dander is ticking off my allergy.

Never mind.  There is a short humorous allegory about this stuff in my story Entanglements, with petting but no pets.  Spoiler alert: quantum theory wins.

Getting You’re Not Late and Entanglements and 27 other stories is easy.  Just buy RH-2.  To consider buying it from Amazon as either a printed book at $11.50 or an e-book at $2.99, click here.  To consider buying an e-book from other retailers at $2.99, click on the rabbit.

To see the Disney version of the Cheshire cat do its thing, U can get to a video on Facebook by clicking on the cat’s image here.  Clicking twice on the cat’s image there will start the video, but only buying RH-2 will get U to the 29 weird stories.

Partially Reflected Light

There is much to celebrate in the simple act of flipping a switch, and the resulting light provides many other mundane miracles to ponder.  Look closely at a partial reflection in the window.
(BTW, the [Menu] button atop the vertical black bar reveals the widgets.)

As the natural light outdoors fades, a mundane miracle occurs.  Tho I have no supernatural powers, I create light and see that it is good.  I need only flip a switch, and the resulting light provides many other mundane miracles to ponder.

Light ~ Pic and a Word Challenge #133

Before I close the curtains, a pine tree across the lawn is still visible thru the window.  Conversely, a bird roosting in the pine could see the light fixture I have just turned on.  Most of the light that my fixture throws toward the window goes right thru the glass, harmless and unharmed.  My fist could not do that.

It gets better.

Some of the light that hits the window is reflected back.  I see my fixture as a ghostly sphere, apparently hovering between me and the pine.  Hmmm.  Consider a single photon among the zillions that whiz from my fixture toward the window.  How does it decide whether to continue on toward the pine or bounce back toward me?

globe-pine-1_840x840

I know.  Photons are mindless particles that do not decide anything.  They just do whatever a divinely perfect knowledge of physics would say they do, and a humanly possible imperfect knowledge of physics is rather good at saying what big groups of them do.

By far the best current human knowledge says that what a single photon does is unpredictable.  Not just unpredictable because we do not know all the details about the laws of nature or how the photon is moving or what is in the glass where the photon hits it.  Not just unpredictable because exact calculations are not feasible. Intrinsically unpredictable!  On a photon-by-photon basis, even divinely perfect knowledge of the rules and the current situation does not determine what will happen in the next picosecond.  Even God must wait and see.

Dunno whether I will succeed in posting more about intrinsic unpredictability and its consequences.  (Don’t hold your breath.)  Without wrangling equations, a great deal can be still be said about the quantum physics behind partially reflected light and its wider implications.  See pages 173-176 of the excellent book Dice World by Brian Clegg (or web pages like the one U can visit by clicking here, if U do not have the book handy).

Tho I know no Noh …

The [Menu] button (atop the vertical black bar) reveals widgets like the Search box.  Typing just the [Enter] key into the Search box is a way to browse WordPress blogs.

I think I see serene contemplation in this face:

Noh-Mask_gold_800x838

Hmmm.  The face is a mask that nobody is wearing.  Who could be contemplating?  And yet

There is no nothingness.
|Quantum physics finds
|tumult in vacuum behind
|contemplative mask.

If the allusion in my haiku responding to
« Contemplation ~ Pic and a Word Challenge #103 »is too cryptic, I recommend A Universe from Nothing by L.M. Krauss.

While the form is conventional, the content of the haiku may be the farthest outside the box that I have gone.  As of now, anyway.  So the haiku is also a response to
