Schrödinger's Dishwasher

For your consideration: an everyday kitchen appliance -- perhaps very much like one in your kitchen -- that's both clean and dirty at the same time:

          Beloved Spousal Unit: "Is the dishwasher clean?"
          Me: "No, I just emptied it. It's dirty now."

At the instant I said that our dishwasher was "dirty" -- and spoke truthfully -- it didn't have a spot of dirt in it. This pristine, yet fallen state would continue for a few more blissfully ambiguous moments until I fouled the nest, defiling our beloved Putzmaschine with the first crumb-stuck breakfast plate and stained coffee mug of the day.

This ambiguous state of our pre-pastried power-scrubber is related to the Physics conundrum known as "Schrödinger's Cat":

          Schrödinger's Cat's a metaphorical cat
          It lives in a box with a nuclear vat
          When a nucleus decays, a loaded gun is released
          And although the box hides it, the cat is deceased
                    ...or is it?
                                                            -t.s. eliot

To the outside world, the cat is unobservable as it waits for the ax to fall; it's unobservable after the ax has fallen. In some external sense, the cat is both dead and alive at the same time.

Or, consider the moment of any creature's demise. Let's say there is one last atom left in a cat's Central Nervous System that has kept the cat alive; for surely there must be a last one, as there must have been a first one. It's down to its ninth life, as it were, and it's the bottom of the ninth with two outs and two strikes. We know from the Heisenberg Uncertainty Principle that the exact position and state of a particle are mutually indeterminate. Is our beloved kitty dead or alive at the indeterminate moment of the last atom's expiration? Or both?

Notwithstanding any of this, our feline friend clearly picked the wrong box to crawl into; it should have selected our dishwasher instead (or else the curtain where Carol Merrill is standing). It might have gotten clean, it might have gotten dirty, or both; but it surely wouldn't have fallen into the clutches of that horrific sadist Erwin Schrödinger, the mere mention of whom, properly framed, could lift PETA's Freshman Orientation Week fund drive to goal immediately.

I saw the following headline recently: "World's Oldest Person Dies".

Not any more.

UPDATE: Since writing this piece, I Googled "Schrödinger's Dishwasher" to see if Google had indexed the article yet. What I found instead surprised me: one metaphorical variation on Schrödinger's Cat is indeed called Schrödinger's Dishwasher! Imagine dirty dishes inside a dishwasher; then, imagine an atomic switch for the dishwasher whereby the electrical circuit is closed, and the appliance starts, when the atom decays. Are the dishes inside clean or dirty? Or both? It's an equivalent dilemma to the classic metaphor involving an atomic-triggered gun, except that no animals were harmed. Hooray animals!

          It would be such a pity
          If we bumped off the kitty!

Shocked, Shocked About Steroids

Retired pitcher Curt Schilling once wrote an emphatic opinion piece on his 38 Pitches blog about the steroids era in baseball. According to Schilling, it's naive to think that any major league team was completely clean during that era, which he says encompassed his entire career.

It's deflating to realize that such awesome spectacles as the McGwire vs. Sosa home run race of 1998, the tape measure home runs of Bonds and A-Rod, the clutch hitting of Manny Ramierez, and the power pitching of Roger Clemens into his greybeard years have reflected the willingness of players to cheat and owners, executives, and managers to look the other way -- perhaps even encourage the practice.

In addition to steroids, consider: growth hormones (both human and equine); blood-doping (both human and equine); surgical enhancement (Tommy John surgery, LASIK); podiatrics (athletic shoe design); textile science (swimsuit fabrics); applied aerodynamics (curveballs, spitballs, knuckleballs); and statistical evaluation ("Moneyball"). And oh, those lovely East German swimmers! Success and failure accrue not just to athletes but also the technological prowess of the society that sends them forth into the arena.

Given the importance of sports in understanding the capabilities and limits of the human body, and the importance of sports science in developing those capabilities further, is there really a clear, ethical line between physical enhancements that represent cheating and those that are legitimate technological advances? Who makes that determination?

Consider the classical origins of athletics: as a means of inspiring, motivating and testing physical fitness, coordination, teamwork, and strategy -- in preparation for military battle. Somewhere right now, some American kids on combat patrol are probably taking various performance-enhancing drugs in a belief (true or mistaken) that doing so will aid in their muscle recovery or alertness and help keep them alive. Some American captains or sergeants might be encouraging this practice.

Somehow I doubt that the public would react to such "cheating" with the same scorn that it heaps upon juiced ballplayers who, for reasons both laudable and selfish, have given their bodies over to the R&D labs.

Spherical Recreations

Colorful balls are such a pleasing form. They practically shout out loud: "Sports!" "Games!" "Toys!" And above all: "Recess!"

Superballs from the toy store. Billiard balls on the bumper pool table at the the Y, where we had summer day camp. A game of 8-ball with my dad on the pool table at the volunteer firehouse. A croquet game in progress in the backyard. Yellow tennis balls. Yellow golf balls. Miniature golf balls in every primary color. Baseballs, softballs, and wiffle balls; basketballs, bowling balls, soccer balls, volleyballs. Red-rubber kickballs at school. Red cricket balls too, or so I understand. Pinballs. Bocce balls. Nerf balls, even.

That pile of colorful balls at the Ikea entrance -- sanitized hourly by the staff, surely -- in which you can happily lose a kid for an hour. There's nothing that's not happy about a pile of balls.

Which probably explains my current obsession with a simple, freeware computer game that I found on Yahoo: the aptly named "Pile of Balls". It's an absurdly simple, Tetris-like recreation in which you manipulate the falling balls, three at a time, into color groups that vanish when you get four or more together. Every so often, a satisfying little fanfare sounds -- "Ta-daaaaa!" -- and you advance a level. I have yet to survive Level 7, but it's not for lack of trying.

Toy models of atoms and planets in science class are fun, too. Speaking of which, I've been following the updates of American astronaut Mike Massimino (@Astro_Mike) on Twitter. He'll be on the Space Shuttle that launches into orbit in about a week. I'm really envious; pretty soon he'll have a large blue and green ball out the window to play with.

Have Wait's Laws Been Refuted?

We have previously introduced and discussed Wait's Law and Wait's Second Law in this space. Namely:

(1) Everything in adult life costs $500.
(2) $800 is the new $500.

Today, however, a striking challenge to Wait's Law and Second Law arose, shaking my confidence in an orderly universe. Specifically, the Silver Zloty's car battery required replacement. Even opting for the Sears Die-Hard with the longer warranty, the invoice came to only $131 including tax, a far cry from the theoretically incontrovertible parameters previously set forth.

As with Rutherford's gold foil experiment, we cannot merely discard observations that seem inconsistent with existing theory. We investigate further.

Reviewing: it's true that today's charges fell short of the mark, and that the damage to the household treasury was, if not minimal, moderate. It's also true that this modest expenditure was voluntary, in part, as the battery had recharged itself adequately during the drive to the store since its earlier failure during the day. Does this fact account for the apparent exception?

(Aside: Is there a better unclaimed name for a rock band than The Cold Cranking Amps? Answer: No.)

Then it happened. The service technician uttered those magic words: "Mr. Wait, can I show you something?"

He points out the loose engine mounts. Price to replace: $800. The guy at Sears spotted them, for Pete's sake. Clearly Wait's Laws hold; confidence in their universality is restored once again. Naturally, I declined to have the work done this time, as before. Who has $800 just lying around?

Which leads us immediately to Wait's Third Law:

(3) If you think Wait's First and Second Laws don't apply: buddy, just you wait!
