Topic Tuesday #64 2013/10/08 - "Rose Colored Glasses & BS Detector Goggles"

I am, by nature, an inquisitive person. I do not take anything at face value. Everything needs to be respected enough to first give it some thought before drawing any conclusion. There are always shades of grey and multiple points of view. What these POVs have in common are facts. It's been said you are entitled to your own opinion, but not your own facts, and I adhere to that in my daily life. It is important to not get lulled into a false sense of reality, as many of the opinions you have were manipulated without your knowledge a long time ago (maybe generations in the past). This, at its core, is skepticism. Doubt.
We have many built in tools for detecting fraudulent things. The ability to recognize deception is something we have honed over millennia. At the heart of the matter is a misinformation maelstrom; an arms race of lies. Better detection, better lies. Many concepts are so susceptible to deception that we think they are true, time and time again. The rose colored glasses of what we wish to be true, regardless of facts. And then...  Conspiracy theories! Delicious tabloid lies!
I love a good conspiracy theory, as much as the next guy, and can certainly buy into them from time to time. It takes patient research to ferret the facts out of a "conspiracy" for one simple reason, most of the information is factual. The conspiracy just strings multiple facts together with leaps of logic that are just outlandish enough to be both interesting and possible, even if unlikely. The more grand and secret they are, the more they play on our psyche.
We have to bust out the BS Detector Goggles and put away the rose colored specs that make life just a beautiful and heart warming paradise. What we need are tools. Here is a list inspired and expanded from Carl Sagan's own "Baloney Detection Kit" born from "The Demon Haunted World".
* First, we have to have data. As much hard data as possible. Quantifiable facts are all you should be interested in until it is time to reason beyond them.
* Whenever possible there must be independent confirmation of the facts. Verification is important.
* Now, quickly you can apply Occam's Razor, and then Hitchen's Razor in turn.
  Occam's Razor: "The simplest answer is often correct." (Very powerful tool.)
  Hitchen's Razor: "What which can be asserted without evidence can be dismissed without evidence."
  With the one/two punch of these epistemological razors, you can quickly cut to the heart of an issue.
* Brainstorm. Don't simply run with the first idea that caught your fancy; spin more than one hypothesis.
* Tear it apart by yourself. Try to defeat the hypothesis. Can you falsify the argument? Is it testable? Can/have others duplicated the experiment and the result?
* In testing the arguments hypothesis, did it rely on shaky information? You've heard it before (and with good reason), a chain (argument) is only as strong as its weakest link.

**When dealing with people, I highly recommend familiarizing yourself with "Logical Fallacies". We use them all the time in our speech and politicians pop them out every few words. I suggest taking a look at https://yourlogicalfallacyis.com/home and http://www.fallacyfiles.org/taxonomy.html but here are a few of the very popular:
* Begging the question (assuming an answer in the way the question is phrased).
* Ad hominem - attacking the arguer and not the argument.
* Straw man - caricaturing (or stereotyping) a position to make it easier to attack.
* Argument from "authority".
* Loaded Question - a question that couldn't be answered without appearing "guilty".
* Argument from adverse consequences (putting pressure on the decision maker by pointing out dire consequences of an "unfavourable" decision).
* Appeal to ignorance (absence of evidence is not evidence of absence).
* Confusion of correlation and causation.
* Post hoc, ergo propter hoc - "it happened after so it was caused by" - confusion of cause and effect.
* Meaningless question ("what happens when an irresistible force meets an immovable object?).
* Non sequitur - "it does not follow" - the logic falls down.
* Special pleading (typically referring to god's will).
* Observational selection (counting the hits and forgetting the misses).
* Statistics of small numbers (such as drawing conclusions from inadequate sample sizes).
* Misunderstanding the nature of statistics (President Eisenhower expressing astonishment and alarm on discovering that fully half of all Americans have below average intelligence!)
* Inconsistency (e.g. military expenditures based on worst case scenarios but scientific projections on environmental dangers thriftily ignored because they are not "proved").
* Suppressed evidence or half-truths.
* Excluded middle - considering only the two extremes in a range of possibilities (making the "other side" look worse than it really is).
* Short-term v. long-term - a subset of excluded middle ("why pursue fundamental science when we have so huge a budget deficit?").
* Slippery slope - a subset of excluded middle - unwarranted extrapolation of the effects (give an inch and they will take a mile).
* Weasel words - for example, use of euphemisms for war such as "police action" to get around limitations on Presidential powers. "An important art of politicians is to find new names for institutions which under old names have become odious to the public"

Now hopefully you have prepared your own kit and can interrogate the world for facts.
Don't let the skeptics of the skeptics get you down either. Just because you traded your rose colored lenses in for a magnifying glass and ask a lot of questions and seem rather contrary, doesn't mean that the reality we share has changed, or that something tastes different because you know more about it. What they will be unhappy with is not being able to get a fast one over on you any more.
I'm all out of gum, watch out for the weasel words!

Topic Tuesday #44 2013/05/21 - "The Finger of God"

The devastation in the heartland cannot be ignored. We will not go into the bloodshed and human damages imparted to us by the recent rash of twisters through Oklahoma. We must look ahead so I will talk about the power of nature and how we classify these storms.

The National Weather Service was instrumental in saving lives by having a tornado warning in effect 16 minutes before the 2 mile wide twister wrought havoc on the ground for over 40 minutes traveling 17 miles. This was the worst of a series of storms that devastated 16 counties in Oklahoma over the weekend.
Tornados are measured on a severity scale, similar to hurricanes. Let's be clear however. To equate the two would be like saying trench warfare in WWI was the same as the bomb dropped on Hiroshima in WWII. Hurricanes are a slow burning bonfire; tornadoes are kegs of black powder and nitro thrown into a volcano.
In 1971, Dr. Tetsuya Fujita and Allen Pearson came up with a scale (F-Scale) for measuring the intensity of tornadoes by their damage path. 
In 2007, the scale was updated to its current form, the Enhanced Fugita Scale

Each damage level is associated with a wind speed however, the Fujita scale is effectively a damage scale, and the wind speeds associated with the damage listed aren't rigorously verified. 

Basically, rating the damage of a tornado is as much an art as it is a science.
For a write up on what is entailed in the EFScale, follow the link below. The reading is fascinating but dry.
http://www.depts.ttu.edu/weweb/Pubs/fscale/EFScale.pdf

What we are usually concerned with is the F0 - F5 range.

  • F0 - Wind: 64-116 km/h - Damage Path Width: 10-50 meters - Damage: Light. Heavy storm style
  • F1 - Wind: 117-180 km/h - Damage Path Width: 10-50 meters - Damage: Moderate. Hurricane force winds, roof surface damage, light structures damaged.
  • F2 - Wind: 181-253 km/h - Damage Path Width: 10-50 meters - Damage: Significant.  Roofs sail away, trains overturn, large trees snap, highrise windows blow in.
  • F3 - Wind: 254-332 km/h - Damage Path Width: 200-500 meters - Damage: Severe. More and worse, larger missiles, some cars leave the gound.
  • F4 - Wind: 333-418 km/h - Damage Path Width: 400-900 meters (1/4 to 1/2 mile) - Damage: Devastating. Well constructed homes demolished. Cars take flight.
  • F5 - Wind: 419-512 km/h - Damage Path Width: 1100 meters (3/4 of a mile) - Damage: Incredible Car size missiles hurled 100+ meters, bark on trees removed, steel reinforced concrete structures damaged

The storm in Oklahoma, would be beyond an EF5. It's damage path was over 1.5 miles wide.
No one every really classifies tornadoes beyond an EF5. But now, you know why storms of such magnitude are referred to as "The Finger of God".

Topic Tuesday #42 2013/05/07 - "Disruptive Tech"

I love technology. I love history. I love science and science fiction (the inspiration for more of the former). The last few days have seen a turn in the direction of what was thought of just at the top of the year as pure science fiction. Well, when I say thought of, I mean all but those with their eyes on a gun manufacturer here in the United States. Defence Distributed, and its front man Cody Wilson, have dreamt up a cottage industry in disruption. Cody, over the last year, has designed and now succeeded in building a fully 3D printed firearm called the Liberator. It's designed as a homage to the single shot weapons that were air dropped over France during WWII. Besides that, the weapon is all plastic save the nail used as a firing pin. The plans have been released to the wild. Anyone can make one of these if they so desired.
And that is outstanding.
Don't think so? Let me explain my stance.
Freedom.
Oh... You probably want more of a platform than that. OK, look at it this way, this is a technology that cannot be stopped. It cannot be regulated to the governments liking and never will be without massive outrage. This is manufacturing in your garage. Dream it one day, make it the next. You don't need permission. You just need the know how, the raw materials and the tools to put them together. Cody made a gun. Will this gun be used to hurt someone? Almost certainly. This is a logical progression to this kind of device (3D printer). Think for a moment as I stroll down technology of years past lane. When Gutenberg and his movable type printing press came on the scene the scribes were out of a job, and it was revolution in the streets (Martin Luther ring a bell?). When the cassette tape was released and you could record onto it easily, the Recording Industry lost their minds. When the VCR came out the Motion Picture Industry went nuts. CD Burners, DVD Burners, BlueRay burners MP3, MP4, JPEG things that can make a copy of something without the originator getting their due, will always be disruptive. I recall that digital copiers were so good at color reproduction that they were used in counterfeiting operations. The Liberator is a statement and a loud extension of this phenomenon. This says, "You can't stop the future. This is the information age, and now we can make use of that information - whatever form it takes."
It is a shake up. It is a wake up call. What that call sounds like changes depending on who hears it, but really it's about freedom.

Personally, I knew this was coming, and making my own gun if just not my cup of tea. Personally, I would rather be the toy maker or make replacement parts and mockups for my own projects. But that is what most people will do. Again, take the internet as a case in point. When it was started, there was no security, no anti virus, no pictures... It was innocent, with innocent ideals. None of those early engineers considered that it would be used for terrorism, free speech, porn, dating, and social networking, or even voice and video. It proved to be disruptive. In a very short time, look how far it has come! Now, where will 3D printing go as the technology becomes less and less expensive?  In less than 10 years, I can see the personal 3D printer all over. Remember inkjet printers were very expensive when they first came on the scene; now they are practically disposable. The printer they used for the gun, was $10,000 on ebay second hand. You can get a MakerBot for considerably less. http://store.makerbot.com/ And I encourage you to go make something.

What will your imagination make next? Will regulation over these devices stifle creativity and rapid prototyping with red tape? Will it just be impossible to regulate, like desktop printing and copy machines?
What do you think?
