The Mavericks
With apologies to Edgar Allen Poe
Once upon a midnight weary, the Mavs did beat the Lakers clearly
Over many a foul and furious shots within the Center's core.
While I shouted, nearly rasping, suddenly there came a tapping,
As of some one loudly gasping, tapping on the wooden floor.
"Tis the Lakers," I uttered, "gasping up and down the floor -
Only them, and nothing more."
Ah, clearly I can say, twas in the joyous month of May
That each three pointer the Mavs did make, left no mark upon the wooden floor.
Eagerly I await tomorrow; - tickets I had sought to borrow
To relieve the past of sorrow - sorrow for the losses that came before
For the rare and jubilant reason to avenge the losses that came before
Forgotten now for evermore.
And the sad but certain unravelling of each yellow and purple jersey
Thrilled me – filled me with fantastic feelings never felt before
So that now, to the beating of my heart, I stood repeating
“Tis some visitors, getting swept upon our Center floor –
Some Laker visitors, getting clearly swept upon our home floor.
This it is, and nothing more.”
Presently my team grew stronger, hesitating then no longer,
“Sir,” said I, “or Madam, truly your indulgence I implore;
But the fact is I was clapping, as so weakly you came rapping,
And so faintly you came tapping, tapping upon our wooden floor,
That scarce was sure I heard you” – here we opened wide the score.
Lakers there, and then no more.
Deep into that score peering, long I stood there clapping, cheering,
Seeing, dreaming dreams no fan had ever dared to dream before.
But the shouting was unbroken, and the Lakers were but tokens,
And the only word there spoken was a shouted, “Gone in four!”
This I shouted, and the walls echoed back “Gone in four!”
Merely this, and nothing more.
[there may be more to come]

Song: Flying with the TSA
Flying with the TSA
[to the tune of “Charlie on the MTA”]
[Spoken: This part isn’t on some of the recordings]
These are the times that try men's souls. In the course of our nation's history, the people of this nation have rallied bravely whenever the rights of men have been threatened. Today, a new crisis has arisen. The Transportation Security Agency, better known as the TSA, is executing illegal assaults on the population in the form of unconstitutional searches. Citizens, hear me out! This could happen to you!
[Sung:]
Well, let me tell you of the story of a man named Charlie,
On a tragic and fateful day.
He put his phone in his pocket, kissed his wife and family,
Went to fly in the USA
(Well, did he ever return? No, he never returned.)
(And his fate is still unlearned.)
(He may remain forever at the TSA checkpoint.)
(He's the man who never returned.)
Charlie showed them his ticket at the TSA checkpoint,
Just hoping to catch his Plane.
When he got there the agent told him, "One more pat down."
Charlie could't get onto that plane.
(But, did he ever return? No, he never returned.)
(And his fate is still unlearned.)
(He may remain forever in the airport terminal.)
(He's the man who never returned.)
Now, all night long Charlie stands spread eagle,
Wonderin’, "Where will they touch me next?
I can’t let this happen to my sister in Dallas,
It’s all based on a false pretext”
(But, did he ever return? No, he never returned.)
(And his fate is still unlearned.)
(He may remain forever in the airport terminal.)
(He's the man who never returned.)
Charlie's wife goes down to the TSA checkpoint,
Every day at quarter past two.
And she keeps filming those pat downs as Charlie stands helpless,
As the TSA searches continue.
(Well, did he ever return? No, he never returned.)
(And his fate is still unlearned.)
(He may remain forever at the TSA checkpoint.)
(He's the man who never returned.)
Now citizens of the nation, don't you think it's a scandal,
How people are assaulted every day?
Fight for sane and sensible airport security!
Let’s get rid of the TSA!
(Or else we'll never return. No, we'll never return.)
(And our fate will be unlearn'd.)
(We may remain forever at the TSA checkpoint.)
(We'll be the ones who never returned.)
(We'll be the ones who never returned.)
(We'll be the ones who never returned.)

Poem: Divisionist History
Divisionist History
We fight for many reasons,
We fight for what we believe.
We’re right, they’re wrong,
And they’re trying to deceive.
We start a fight, or defend ourselves,
In battles won or lost.
War rages on forever,
And no one knows the cost.
We teach “divide and conquer”,
Study tactics and strategy.
And each day we keep on killing,
Because they’re not like me.
We keep building better weapons,
To kill Them more efficiently.
Why should we even care a bit,
They are the enemy.
Millions die and billions suffer.
The atrocities abound.
A dozen here, thousands there,
We’re indifferent to the sound.
To some “it” never happened.
Others argue that “it” did.
Some say “it” might have happened,
But not the way “They” said.
Each side tells their story,
Convinced that what they say is true.
But the victors always get to say,
And write history anew.
We’ll never truly know the reasons,
Only what the victors say,
Cause They’re the ones who write the books.
It doesn’t matter anyway.
One day I hope we’ll stop the madness,
It’s causing quite a fright.
But that doesn’t really seem to matter,
When we go to bed at night.
We’re no specific country,
Nation, state, or faith.
Nor race, nor creed, nor color,
We are the human race.
We can’t ever know the reasons.
We can’t begin to count the cost.
We can’t even know the truth.
We can only mourn the loss.
But any way you view it,
I hope we all can see.
Our righteousness perpetuates
Our divisionist history.

Why the EPA Limits for Drinking Water Are Irrelevant to Radiation From Japan
Originally published as a note on my Facebook page Apr 25, 2011
The most recent results for iodine-131 levels in milk in Arizona have been widely misrepresented in media coverage as 1600x the EPA limit for drinking water. In fact, it's 16x (1600%), however, even that is meaningless. In fact, the EPA doesn't have a level for milk, and comparing it to the drinking water level is flawed as a level for milk and drinking water would not the same due to the differences in daily consumption. So any comparison to EPA levels is complete nonsense. The EPA levels serve a different purpose than the FDA levels, see info on EPA levels below. BTW, AZ publishes the readings from testing water and milk at http://www.azein.gov/azein/2011/Data%20landing%20page.pdf
The FDA sets limits for food and drink (including milk and drinking water), and the highest level reported is ~ 1/1000 of the FDA DIL (Derived Intervention Level). Now the FDA DIL is probably too lax for drinking water because of the amount of water consumed daily. For food and milk, the FDA limits are better, but are arguably still too lax (at least for extended exposure). However, they're far more appropriate to a transient exposure, and they're specific to ingested food and drink, so they're far more applicable than the EPA levels in this situation.
http://www.atsdr.cdc.gov/csem/iodine/standards_regulations.html
More info on EPA limits:
EPA limits are based on consuming the MCL every day for 70 years, which is to say they are for a maximum "every day" level, not a maximum "safe" level. The EPA levels don't differentiate between getting the MCL every day for a lifetime and getting a somewhat larger dose for a few days. As a maintenance level, it make some sense, but they don't address transient levels. They are flawed in other ways as well, for instance, they allow 5x higher dose from alpha emitters which are far more damaging when inhaled/ingested than they do for beta and gamma emitters. They allow 5x as much exposure to a type of radiation that is ~ 20x more damaging, how does that make sense?
The EPA limits are occupational exposure limits (Quoted from 40 CFR 141.66(d)(2)):

Notes About Radiation Exposure
Originally published as a note on my Facebook page Mar 29, 2010
Is any level of radiation exposure "safe"? Is all radiation exposure "harmful". Below I apply a bit of logic and sanity to examining the effects of radiation exposure:
There is no difference between "naturally occurring" and "man-made" radiation exposure at the same level. However, there is a difference between external (radiation source outside your body) and internal (radiation source inside your body) radiation. Internal or external radiation can come from natural or man-made sources. Again, there is no difference between the two, when the dosage and internal/external are the same. In general, inhaled radioactive particles are most dangerous, since they're more likely to get into the blood stream where they can affect any part of the body. Ingested radioactivity is usually not absorbed as effectively and it's less likely to reach as much of the body. Both should be taken seriously. See the "Treatment" section below if you suspect you have received significant exposure,
Radiation comes in basically four varieties:
Alpha - can be very damaging if it reaches living tissue, however, it's easily stopped. A piece of paper or your skin will block almost all alpha particles. It's only a significant health risk if inhaled or ingested in notable quantities.
Beta - can be moderately damaging, but is also relatively easy to stop. It will penetrate slightly below the skin, so external beta sources are similar to a sunburn (for high levels) and the most likely health effects are similar to sun exposure, including possible skin cancer if the exposure is high enough for a long term.
Gamma - X-rays and "cosmic rays" are types of gamma radiation (technically, x-rays and gamma rays are different, but the difference is not important here). Because it's very common and more difficult to block, this is the type of radiation that we hear most about. There is little difference between internal and external exposure to gamma radiation because your skin and clothing provide almost no protection from it. It's a mixed blessing, as most will pass through the body without any effect, but some percentage will interact with atoms in your body. The percentage that interacts with your body can do significant damage in high enough doses.
Neutron - rarely encountered in notable levels outside of a nuclear reactor (or nuclear weapon), but it does exist in low levels in nature. This can cause atoms to split, or absorb a neutron, which may then give off a minute amount of one of the above 3 types of radiation. Most will pass through your body without interaction. Most of the atoms in your body are not prone to splitting, so low doses will have minimal impact on living tissues.
With any of those 4 types, low dose has no measurable effect on your body because most damage will either cause cell to die and be replaced, or your body is able to repair the damage quickly. However, a sufficiently high dose of any type, or an "unlucky hit" from a lower level, can cause more damage than the body can repair, or a type of damage that the body can't repair, thus causing short term or long term damage.
Given the above, it is incorrect to say that all radiation is harmful, as the vast majority of it will either have no effect at all or will do less damage than the body can repair. It's equally incorrect to say that any level is harmless, as an "unlucky hit" from a very small dose can cause a long term problem, it's just statistically extremely improbable.
Below the maximum "safe" levels, you have much better odds of winning a huge lottery jackpot than of having measurable long term effects. Between the maximum "safe" levels, and approximately 500 mSv in less than 48 hours, your chances of both short term and long term effects increase significantly with increasing dosage. Above 500mSv in 48 hrs, your chances of short term and/or long term effects become probable (e.g. at those doses, you're likely to have effects).
Because your body is constantly repairing and replacing cells, the same total dosage received as a lower dosage over a longer time (e.g. 5 mSv/day for 100 days rather than 500 mSv in one day) is dramatically less likely to cause any measurable short term or long term effects.
Clearly, minimizing your exposure minimizes your risk. But also realize there are levels below which the risk is not even measurable. Worrying about exposure below (or even slightly above) the maximum "safe" levels is about as useful as worrying about getting hit by an asteroid or whether the sun will rise in the morning. Likewise, for worrying about brief exposure to higher levels such as receiving a CT scan or PET scan.
A simple analogy:
To put radiation exposure in terms just about everyone can understand, it's a lot like alcohol.
Too much in a short time will make you ill, or possibly kill you. That same amount spread out over days, weeks, or months won't even make you ill. However, too high a level long term can cause problems (e.g. cirrhosis, pancreatitis, cancer, infertility, etc.). Low doses for a long time are not known to cause problems (and at least with alcohol, appear to be beneficial).
In either case, if the dose is below what your body can process and repair any minor damage caused, there are few or no long term effects. If you exceed that level by too much, or for too long, the risks increase with both dosage and duration.
Treatment:
The first thing to know about getting treatment for any suspected radiation exposure is to seek medical treatment and decontamination immediately. If you have reason to believe you've been exposed to more than the maximum "safe" level, do not hesitate, seek immediate testing, decontamination, and treatment. This is particularly important if you may have inhaled or ingested a radioactive substance. Most common radioisotope inhalation or ingestion can be treated, but urgent treatment is critical to effective treatment.
For the two most common isotopes that released in nuclear power plant accidents, treatments are commonly available. For iodine-131 (aka 131I or I-131), treatment is usually done by taking potassium iodide (KI) tablets. This saturates the thyroid with non-radioactive iodine, minimizing the amount of I-131 that will be absorbed. For cesium-137 (aka 137Cs or Cs-137), treatment is usually done with medical grade "prussian blue". Prussian blue binds to many heavy metals, including Cs-137, and carries it out of the body. In both cases, the key is to get treatment BEFORE any significant amount has been absorbed by the body.
Most other radioisotopes can be treated, if treatment begins quickly enough.
Prevention:
Activated charcoal filters are effective at reducing the amount of iodine in air/water, so if your water supply has elevated levels of I-131, a good charcoal filter will help. Air purifiers that use activated charcoal will help remove I-131 from the air.
Charcoal filters will also remove some heavy metals, so they may reduce the level of Cs-137, but unless they've been specifically designed to remove Cs, they are not as effective at removing Cs as they are at removing iodine.

This one is easy to comprehend, but some the the technical details are wrong so don't rely on the details. The overview and debunking of false claims are solid. True facts about Ocean Radiation and the Fukushima Disaster

Major Security Oversight
Originally published as a note on my Facebook page Nov 18, 2010
Ladies and Gentlemen, flight crew and flight attendants, we have overlooked something major. The White House, US Capitol, and the Pentagon are all known terrorist targets. Planes were merely the method used to attack those targets. If terrorists can no longer use planes to attack these targets, they will use more direct attacks. Therefore, we need to petition our government to immediately install backscatter scanners and implement enhanced pat-down procedures at each of these locations.
No one should be allowed to enter these facilities without going through the scanner or pat-down. Not our elected officials, not the military, not the employees, not even the President, first lady, or their young daughters. These are high value targets, and we can't be too safe. In fact, given that the backscatter machines do not show anything inside the body, they should install both backscatter and millimeter wave scanners and everyone must pass through both to be sure they're not carrying any contraband.
Furthermore, if the terrorists can disrupt our security forces, that would give them more access, therefore the DHS and TSA offices become high value targets too, and they must also have these scanners and pat-down procedures immediately.
I believe we should extend this to all state government capital buildings as well, or at least for the most populous states, NY, CA, FL, TX, OH, IL, PA, MI, GA, NC, NJ, & VA. We should include MD because of it's proximity to DC. And we should include AK, HI, and RI since they're physically disconnected from the continental US.
Please, I urge you to immediately contact your state and federal representatives demanding that they correct this oversight that puts the entire government of the country at risk of terrorist attack, and by extension, puts everyone in the country at risk. I am horrified that we've left these high profile targets unprotected for this long.
Satirically yours,
Geoff Strickler
P.S. I was going to title this "Porno scanners and en-hands-ed feel-ups everywhere", but I didn't want to give away the satire too soon.

Song: Don't Fly
Originally published as a note on my Facebook page Nov 16, 2010
Don’t Fly
(to the tune of “Don’t Cry” by Asia)
Original Songwriters: John Wetton & Geoff Downes
New lyrics by Geoff Strickler
Hard times you had before you, I knew when they first saw you
You girl, you’re gonna be selected, inspected
So leave your stuff behind you, they’ve looked so long to find you
I know this search will last forever, ever and more, oh, oh, oh
Don't fly, now they’re gonna hound you
Don't fly, they’ll take a look around you
Don't fly, their groping will astound you
They do what they want so little darlin' please don't fly
I knew you’d be selected, knew you would be rejected
Don't think it’s like it’s been before
They'll watch you when you're scanning, they’ll grope you when you're standing.
Don't argue if you want to ever get on board, oh, oh, oh
Don't fly, now they’re gonna hound you
Don't fly, they’ll take a look around you
Don't fly, their groping will astound you
They do what they want so little darlin' please don't fly
(repeat previous verse 2 more times)
Don't fly, don't fly, don't fly
Don't fly, don't fly, don't fly
Don't fly, they’ve looked so long to find you
Don't fly, they’ll take a look around you
