Yes - It's That Time of the Year - Again - To Say Lots and Do Nothing
June 2, 2010
It's time to stop being nice about this issue. This has gone on for a decade now, and the numbers have only gotten worse.
Where, in the private sector, would declining results over a 10-year period be tolerated?
The government collects data. The attorney general issues an annual report. IT'S VIRTUALLY THE SAME REPORT EVERY YEAR!
Law enforcement agencies give the same explanation year after year. The stops are correctly reported, but the underlying population numbers are meaningless.
And another year passes.
Missouri has been hailed as a leader in the reporting of vehicle stops. This is true.
Missouri has a lot of data - so much they're drowning in an ocean of data - in search of INFORMATION!
This time, we're taking the offensive.
The real data is out there - and I'm going to get it. I've laid out, in previous years' columns, a proper method of analyzing this problem. Get out of the way, you clumsy numerical oafs, who think "the data is what it is".
Analysis to follow, as I retrieve the real data ...

Kansas City Fountains and Sculptures
June 7, 2010
AKA: Flame Fountain
Description: The Pegasus was originally placed on the Country Club Plaza in 1954 and had a small, winged horse as the focal point. It was the work of sculptor Wheeler Williams who had also designed the Muse of the Missouri Fountain. In 1963, Pegasus was moved to a new location on West 47th Street near Broadway. When the fountain was moved, it was redesigned and now consists of a bronze bowl mounted atop the pedestal, equipped with a gas jet to produce flames. The water elements of the fountain were not changed and still consist of the circular arcing jets that spray toward the center of the pool. It enjoys a popularity resulting from its mixture of fire and water.
Location: in median at 47th & Broadway, Kansas City, MO
Date erected: 1954
“Pan (Bacchus) Fountain”
AKA: “The Nymphs of the Forest, Fields, Rivers, Fruits and Flowers of the Earth Paying Homage to Pan”.
Description: A sculptural group set within a quatrefoil basin. A central male bust, a terminal pedestal, is surrounded by four female figures. Figures represent Bacchus holding court, surrounded by his female nymphs and male satyrs. Male bust of Bacchus depicts a youthful head with flowing locks of hair. Grapevines curl around the pedestal. Oak leaves and acorn form a wreath in his hair. The female figure to the left of Bacchus on the north elevation is portrayed kneeling and looking backward with an upraised arm that supports multiple folds of drapery. Her backward gaze is directed toward a cloven-hoofed satyr figure who is reaching up to touch her with a pine branch. To the right of Bacchus on the north side of the sculpture, a female figure is looking up at the central bust and a child’s figure is holding a garland of flowers and leaning back against her. A child figure with insect-like wings appears on west elevation. The south elevation contains a female figure who gazes outward, portrayed with sheaves of wheat beside her and sprigs of wheat in her hair. She holds a cornucopia. The adjacent figure on the south side has a cat-o-mine tails in her hair and holds a scallop shell. The child figure in front of her and beneath her is shown on his hands and knees in pursuit of a frog. His legs end in a webbed tail-like form suggesting a mermaid figure.

Muse of the Missouri
Description: The Muse of the Missouri is located in the heart of downtown. Based on classical mythology, this creation of artist Wheeler Williams personifies a goddess bestowing her interest and guidance on the Missouri River. Williams had originally intended to use fish native to the river spilling from the net. However, he found catfish too ugly and carp unworkable. The nine fish netted by the muse are a hybrid using a carp body and bluefish head. There are 200 spouts of water making up the total fountain display.

Caught in a Bind
June 8, 2010
While in Chesterfield, MO, over the weekend, I came upon an
interesting article in the St. Louis Post Dispatch.
We all know what it said. We can guess what happened. It's been in the news in every community in America.
A criminal flees. Police pursued. An innocent bystander died.
Let's back up a second, and capture all that I just said in a quick logic diagram. There's a crime, and the police are in hot pursuit. Inevitably, there's a collision. An innocent bystander dies. The public? Outraged. The result? A change in policy - only pursue "dangerous-crime" criminals.
Of course. It's an issue, as I said, arising everywhere.
And this leads to the article I referred to. You see, auto-thefts were on the rise. They were sky-rocketing. Why? Criminals, of course, knew police would not pursue! And the public? Outraged! Pursue ALL criminals!
And you see the viscous cycle that results ..
Is there any way out of this feedback loop? Is this a forever tug-of-war between the good guys and the bad?
Let's check our premises. Our assumptions.
The dilemma - the conflict: pursue / don't pursue.
Why would we pursue? Of course, to capture criminals.
Why would we not pursue? It takes only the death of one innocent bystander to verbalize this - to ensure public safety?
That seems to make sense, but at the same time, is this the reason police would not pursue a criminal, or is this the goal of the law enforcement community?
Let's diagram this out ...
One thing that stands out immediately, merely in writing this down, is the idea of ensuring public safety. Is it really ensured if policy don't pursue non-dangerous criminals?
Who says they're non-dangerous? Merely because they're stealing cars? If they're stealing cars, what else are they doing? What other crimes have they committed, if they're willing to break into a car and flee at high speeds?
Yes, occasionally - and sadly - an innocent person is killed in pursuit. This is a high-profile death. There's also 10 times that many people killed in less-than-high-profile deaths every day. How many of these people are killed - needlessly - by criminals once considered "non-dangerous".

Let’s see. Let’s also incorporate some of the information we’ve used already:
This looks a little messy. Let’s clean it up by simplifying:
To make sure we’re on the same page, here’s what I got, solving for S:
My goodness, am I done yet?
You see, S is the base of the entire triangle. That’s OK, because I need that for the formula for the area of the triangle.
However, I also need the height h, and in finding the height, I’ll (again) be using tangent. But as you can see, the relevant “run” is really b. This is ½ of S --- easy enough to find:
What’s the area of our triangle? That’s what we want to know!
OUR FINAL TRIANGLE!
Please expand this, as you would an ordinary situation with two factors like (´ + 4)( 2´ - 7):
within a Fixed Equilateral Triangle: a summary
Why does our formula have an ‘n’ in it? Let’s remember we kept the radius of the circle set at 1. So the length of the sides depend on the number of circles n we’ve embedded.
Given n circles on the bottom row, each with radius 1, the area of all circles is
and the area of the external triangle is:
Let’s take a quick break.

COLORING THE MANDELBROT LANDSCAPE
Let’s recall our earlier graph of the behavior of the Mandelbrot Set as the escape value is changed:
Briefly, this “escape value” told us how long to check a point to see if it’s in the Mandelbrot Set. The idea was many patterns of distances go like this: 1, 2,4, 8, and off to infinity quickly. Other sequences cycle through a pattern like this: 1, 1.5, 1, 1.5, etc. In both of these cases, we have an idea quickly about what’s going to happen.
Other times, we don’t have such a quick idea. For example, what about this one:
It’s tough to tell what’s going to happen, because this thing seems to be bouncing all over the place. But we have to put a limit on how long we’ll check, and we called this the “escape value”. If our process escapes within a certain period, great. If it doesn’t, we assume it never will.
Well, not exactly. We just mark the result as “not escaping”.
In Volume #1 of =EQUALS=, we captured the images of certain escape values.
But is there a way to put all these images together into one consolidated image? Let’s just color the image and see:
Maybe nothing to those of you who have used many wonderful fractal programs on the internet, but additionally wonderful to me since it was done in Excel.
What else can Excel tell us?
As the color changes, it means a process was at one point considered “under control” (meaning it didn’t escape before a certain number of iterations), but when that threshold (escape value) was increased, it was found that behavior did change - and exceed our threshold distance.
So there’s some behavioral change going on. Let’s see how the points change over time. Let’s extract 62,500 points from our grid, equally spaced across this 250 ´ 250 grid:
and set our escape value to 1,000. That is, if the sequence does not escape by then, we stop. We don’t necessarily say it will never escape, but merely that it didn’t by this point.
What’s the distribution of points by ‘escape value’? But first, what do we expect? Looking at the above graph (iterations 1 – 9), we see a lot of color changing. Each point within a color change means changing the escape value threshold changed the graph. So we expect a lot of early changing.
Of the 62,500 points checked, 15,140 never escaped. That means 47,360 points did escape! But how fast did they escape? Let’s graph it:
Indeed, a lot of changing. Not included here are 15,140 points that made it all the way to the 1000th calculation, and were still within the threshold.
But there’s additionally a lot where the change took place above 25. What can be going on here? Fortunately, because we’ve created all of this ourselves, we can see.
For example, point c(0.03, –0.63) generates a sequence where the escape distance is breached only after 965 iterations!
965 iterations? What does the behavior look like?

The great thing about a spreadsheet is honesty is a virtue. If you're going to graph an ellipse, you need to know the points. You cannot fake reality.
I'm in a spreadsheet now, and I want to find a way to graph all the points on the ellipse.
As usual, I'll start with something specific - two Foci, and a known distance.
Let's get started. Let's just take an x-coordinate at random, say ´ = 8, and move forward with the single goal: find the corresponding y coordinate:
By the Pythagorean Theorem, I have the following:
What else do I know about ellipses? The total distance of the point on the ellipse from the foci is fixed:
Let's put all of this together:
I've solved for one of the distances. Let's use an actual number for the total distance, just to get something on the table ...
and remind ourselves what exactly we've just found ...
And now, concluding, let's find our missing y ...
If we wanted to tie all of this logic together, we could, of course ...
And, more importantly, we could find the general formula for the problem, given any value 'x', what's the corresponding 'y' values such that the points fall on the desired ellipse?
All done --- and in the process of doing all of this, you'll find a ton of other problems arising in your head, plus the confidence to know you can solve any of them!
Part I of "The Nutrition Series"
June 14, 2010
I'm not going to actually eat five Snicker's bars, but let's
suppose I was. What would happen?
Sure, I'd gain weight, and a reasonable question is to ask "Why?" For example, if I ate the same amount of food (weight-wise) in carrots, I'm pretty sure I wouldn't gain weight.
Let's save this question.
Five Snicker's Bars in my system, What would happen to me - besides weight? My blood sugar readings would go up. That must mean there's a normal blood-sugar reading, and this massive influx of sugar has caused my blood-sugar reading to spike.
The body is a miraculous thing. When it realizes there's "unusual" activity, it acts to fix it. For example, when you cut your finger, the body responds automatically to correct the problem. The wound is sealed with clots.
The body's immune system kicks in.
Does the body do something similar when there is too much sugar in the system?
A similar thought comes to mind regarding the oil spill in the Gulf. There's always oil being leaked from the gulf floor into the huge body of water. This is the nature of our planet. However, the massive amount of water merely soaks up the oil - it's a part of the gulf.
Now, however, there is a huge amount of oil spewing into the gulf - an unnatural amount - and the gulf cannot absorb it.
What about our bodies?
When there's too much sugar in the blood stream, what does our body do? It miraculously tells cells to start soaking up the unusual amount of sugar.
What does this?
Insulin is a "sugar-regulator".
Yes - the pancreas. Among many things it does, the pancreas creates insulin, and sends it to the body to inform cells to get ready to "absorb" the excess sugar.
How does the insulin do all of this?
And what happens if insulin doesn't work? Your pancreas doesn't create - or release - it?

(x,y) coordinates (0.3604, -0.318)
Innocent looking coordinates.
Around this area, this specific, you'll see a lot of behavior changes when you change the escape value.
For example, the point above generates stable behavior until the 7,411 iteration, and then it explodes!
What does this behavior look like?
Here are all of these iterations ...
The "wobble" becomes uncontrollable, and the behavior zooms "off to the Milky Way"!

Some Scary Thoughts
June 18, 2010
The leak continues, and the estimates are now up to 60,000 barrels a day. At 42 gallons per barrel, that's 2,520,000 gallons daily.
That's an Exxon Valdez every four days.
There seems to be no end in sight. Is there? Is there a point where "the well runs dry"?
BP CEO Hayward said yesterday the oil reservoir under the Gulf holds 50,000,000 million barrels of oil. And as ominous as that number sounds, the accompanying words are more scary, given the predictive nature of the BP disaster. Remember, the leak started at 1,000 barrels a day, and the 5,000. After a while it jumped to 25,000, and it's now up to 60,000 barrels.
Those two words: at least.
At least 50,000,000 million barrels of oil. At least 2.1 billion gallons of oil.
That's about two-and-a-quarter years of oil flowing, at 60,000 barrels per day.
Can we put a stop to this? That's, obviously, the key question.
Let's see if we can first figure out what is going on. Here's my understanding of the set-up:
After the Deepwater Horizon explosion, the rig sank, taking the riser with it. The riser, connected to the wellhead, severed - partially. A leak ensued.
How do we stop the leak?
Initial attempts to cap the leak included a dome-like structure atop the wellhead. This made sense to me.
But it failed for reasons I still don't understand.
You see, first off, I've got the wrong impression of what the dome was intended to do. My containment dome above sat on top of the wellhead, and sealed everything in. Why not? Problem solved!
Their containment dome put in place was merely to funnel leaking oil from the damaged wellhead and riser to the Gulf surface.
But the dome's opening became clogged with gas hydrates - crystal structures that form when gas and water mix and are found in the low temperature and high pressure at the Gulf floor.
I don't know why this would become clogged, but the riser (when operating correctly) itself wouldn't clog.
And I don't know why it wasn't a dome merely intended to sit atop the wellhead. Maybe the pressure building would be too great, and eventually lift the dome off the Gulf floor. That's probably the case.
I'm still trying to reason through all of the above, but the end result of BP Attempt #1: failure.
Having failed with the "funneling" containment dome, the second attempt was a form of mud-jacking, as I understand it. High-pressure pumps sent mud into the pipe, with hopes of clogging it.
This failed also. I don't know how it could have succeeded, honestly. This attempt didn't make any sense to me, either.
The next attempt was to cap the wellhead, but to cap it meant cutting free the damaged riser, which was bent when the Deepwater Horizon sank. But to cut the riser free meant the risk of increased flow, we were told.
Imagine a crimped garden hose, with water coming out. By removing the crimp, water explodes out of the hose.
Yet this is what they did. And the flow of oil did increase - greatly.
It was necessary to cap the wellhead, we were told.
But they haven't capped the wellhead - and they're not even trying.
And this leads to an ominous scenario: why not?
Part II - tomorrow.
Some Scary Thoughts
June 19, 2010
The riser's been cut, but BP is not even attempting to cap the wellhead. Why not? The only logical explanation, to me, now is the riser was not cut to afford capping.
Why was it cut, then?
To relieve pressure building in the pipe leading from the reservoir to the wellhead.
Because that pipe's been compromised.
If the wellhead were capped, and if the connecting pipe were compromised, then the leak would merely be transferred from the wellhead to many spots along the pipe - and eventually - there would be a massive blowout.
And then it's uncontrollable.
Cutting the riser increased the flow - yes. Dramatically. But it headed off a major blowout.
This explains why all efforts now are on capturing the oil as it rises to the surface, and not stopping the flow.
It can't be stopped.
And this scene from Apollo 13 comes to mind ...
Houston ... we sure could use the re-entry procedure up here. When can we expect that?
That's coming real soon, Aquarius.
Houston, we ... we just can't throw this together at the last minute. So, here's what you're gonna do. You're gonna get the procedure up to us, whatever it is ... and we're gonna go over it step by step, so there's no foul-ups. I don't have to tell you we're all a little tired up here. The world's getting awfully big in the window.
Jim, this is Deke
They don't know how to do it.
"They don't know how to do it".
As ominous as this sounds, I think it gets worse.
Can Nothing Be Done
Relief shafts are on the way.
Two are being dug now, hopefully completed in August.
But what will they do? Here's what I think the situation looks like:
Let's suppose both relief shafts 1 and 2 breach the oil reservoir. What can they do? If both begin pumping oil, and if the total pressure is constant, then the pressure on the damaged pipe is reduced - by 2/3.
But the oil continues to flow, 2/3 directly captured through the relief shafts, 1/3 via funneling from the damaged shaft.
But the oil continues to flow.
And I don't see how it can ever be stopped - until the reservoir is depleted of oil, in a minimum two-and-a-quarter years!
For example, if they are able to finally seal the damaged pipe, there's still oil pumping through the relief shafts. If the flow from either of the relief shafts is ever shut off, the pressure is transferred to the compromised pipe, and then through the fissures! We're back where we started, aren't we?
The only solution: don't focus on the top of the damaged pipe, but the bottom!
But how can one build a containment dome at the bottom of the compromised pipe, where the pipe breaches the oil reservoir?
That, to me, is the crucial question.
And as far-fetched as it may sound, I think I have a reasonable answer. A science-fiction answer, for sure, but nonetheless, something plausible!
To complicate matters, any solution right now hinges on the success of the relief shafts. Industry experts predict a 60% chance of success for any given shaft. If this is valid, what can we expect?
A 16% change we do not breach the reservoir?
As usual, my "map of the territory" is off a bit, which is OK, since I started with no map of the territory at all!
Here is a recent BP image of the relief wells ...
The goal of the relief wells is to drill parallel to the damaged well-head shaft to 10,000 feet, and then angle towards it, intersecting it around 15,000 feet.
However, if they intersect it heading down, won't the oil explode up through the new point?
So, just before intersecting the casing of the main shaft, they turn upwards.
They will inject a type of mud to slow the flow, and then inject quick-drying cement into the shaft.
I hope the success of this mission does not depend on the structural integrity of the casing.
A Short Story about Batting Cages and System Correction
June 20, 2010
We were at the batting cages today. Batting practice.
And with "automatic pitchers", you'd expect the ball to cross the plate at the same place every pitch. After all, it's a machine mechanically throwing the ball!
If 20 pitches are thrown, you might expect this:
Of course, the pitches don't look like this.
There's variability in a lot of places. Every ball weighs just a little bit different. Every ball is built a little bit different. And every ball enters - and exits - the machine a little bit different - every single pitch.
Micro-millimeters makes a difference.
And actual pitches look like this:
Every kid is different, too, in size particularly. My strike zone, for example (I'm 6'7") is different from my son's strike zone.
We need to adjust the machine.
There's this control device:
When you use it, it can be frustrating.
Let's suppose you step into the batting cage. The first pitch:
You walk back to the controls and push the "up" button a couple times. However, it takes time for the machine to accept the changes and re-calibrate itself. You didn't hit the button quick enough, so your changes aren't "in the system". Here's the second pitch:
You hop back to the controls, quickly, and pound the "up" button immediately, in frustration, and this time you hit the button quick enough so the changes do take effect. Now there are four "up" pushes in the system. The third pitch comes across the plate - head high:
Why did the pitch come in this high? Remember, there was natural variation already embedded in the system, so in addition to our four "up" pushes of artificially-added variation, there was the variability already there!
Now we're really frustrated, of course.
What's our next natural reaction? DOWN! DOWN! DOWN!
And the next pitch?
By this time, we're cursing the machine, as we're using up precious pitches on our coin.
"What's wrong with this machine? What's wrong with these buttons"?
Is there anything wrong - or is there something wrong - with us?
What should we do? "When should we push the button?"
"WHEN SHOULD YOU PUSH THE BUTTON?"
You might be thinking - let it go a couple pitches so you can determine the "normal limits" of the machine. Let's suppose the first four pitches were like this:
All four pitches are "below average", but all four are within "normal limits". Would you push the "up" button? Is four enough? Is it too many? And is it count only that matters?
For example, consider these four pitches:
Would you push the "up" button? These, too, are "below average". These, too, are within "normal limits". But there's a pattern. Would you consider something possibly wrong with the machine? Maybe it's slipping.
These four pitches are also "below average" but "within control limits":
It's clearly not just a matter of "number of consecutive pitches below average" that drives your decision. It's location. It's trend. It's consistency.
They all play a part.
The question remains: WHEN SHOULD YOU PUSH THE BUTTON?

In an earlier post, I showed, with one map, three
layers of causality. The position of the earth relative to the
sun. The amount of sunlight during the day, and the temperature.
Today is "Summer Solstice". What does that mean?
After playing around with a number of definitions and simulations with a globe, I thought I had arrived at a reasonable definition: it's when the earth, revolving around the sun, is at it's closet point to the earth. Moreover, because of the tilt of the earth, the circle traced as the earth rotates once at this point is the Tropic of Cancer and the Tropic of Capricorn (if you're in the opposite hemisphere).
This was a cool demonstration.
But I was troubled by it.
Could it be the case just at the point the earth is closest to the sun on its trek about the sun it's also the case it's tilted furthest from the sun?
This is too coincidental.
It can't be right.
I don't think solstices and equinoxes have anything to do with the place in the orbit about the sun.
But where is the ellipse in any of this?
So my new operating hypothesis: equinox and solstice have nothing to do with the place in the revolutionary orbit about the sun.

The Lakers / Celtics rivalry. Game 7. A great game.
The Lakers' franchise now has 16 titles, one behind the Celtics.
So the Celtics have 17.
The two combined - 33.
The league has been in existence since the late 40s.
These two franchises have about 1/2 of all championships.
But it's been a while since the Celtic dynasty of the 60s.
And the Lakers and Celtics share a unique distinction among current franchises - they've been around since the start.
Lots of things going on here - let's try to put it into a visible format:
HOW LONG HAVE THEY BEEN AROUND?
CHAMPIONSHIPS - LOST

The Story of the Pioneer Monument
June 30, 2010
Dr. Chester Warren Chapman, Nevada City dentist, was appointed chairman of the Donner Monument Committee.
It was 1901.
55 years after the Donner Party - yes, that Donner Party - got trapped in the Sierra's.
Chapman became fascinated with the story of the Donner Party.
A suggestion was made not to memorialize the Donner Party, but create a memorial to all Pioneers who headed west.
Chapman knew what these people were like - and liked the idea. These people were courageous, tough, adventurous.
They put the idea to San Francisco sculptor Douglas Tilden. His idea:
"I would like to depict actual privation so that posterity can see and understand. On top I would place the lone pioneer figure [you described]. At the bottom I would place all around in the shadow of the rest, a dozen or so figures sitting, lying, creeping in different attitudes from cowering anxiety to resignation of death."
Chapman didn't like it at all, and shot off this response:
"While I can see all of the elements in the experience of the Donner Party, yet my concept of the Pioneers is that of a type of men who possessed courage, determination and endurance to suffer physical and mental strain, remaining steadfast and resolute to triumph over difficulties under which others succumb. I would want the figure that surmounts this pedestal to show by attitude and mien that he had experienced terrors and strain. I would want the eager, searching gaze to show a realization that the goal was near, and I would like the face to show the light of the conqueror's soul that never fails except through death, no thought of which could be gleaned from the steadfast gaze toward the promised goal. I would not have those who leave its presence exclaim that it was beautiful. I would have them square their shoulders and say, "I CAN AND I WILL!"

Chapman won - fortunately.
