From The Greatest Show On Earth by Richard Dawkins (thanks, Blair):
Behold the mighty dinosaur,
Famous in prehistoric lore,
Not only for his power and strength
But for his intellectual length.
You will observe by his remains
The creature had two sets of brains –
One in his head (the usual place),
The other at his spinal base.
Thus he could reason A priori
As well as A posteriori.
No problem bothered him a bit
He made both head and tail of it.
So wise was he, so wise and solemn,
Each thought filled just a spinal column.
If one brain found the pressure strong
It passed a few ideas along.
If something slipped his forward mind
‘Twas rescued by the one behind.
And if in error he was caught
He had a saving afterthought.
As he thought twice before he spoke
He had no judgment to revoke.
Thus he could think without congestion
Upon both sides of every question.
Oh, gaze upon this model beast,
Defunct ten million years at least.
– Bert Leston Taylor (1866 – 1921)

What jobs (and other unpaid responsibilities) have you had?

You read yesterday’s VatulBlog post on natural disasters and the benefits of educating yourself in this time of information plenty. Where do you start, however, when search engine output has a rather low signal-to-noise ratio?
1) A list of Google’s or Ask’s search terms shows many internet users cannot pose a question to save their lives. Use these 20 Tips For More Effective Google Searches to avoid being overwhelmed by search results. Become one with Boolean.
2) There are many free science search tools out there. Here is a review of the prominent ones. Search early, search often.
3) Ask a librarian. There exist these humans, many Library & Information Science graduates and other smart people, who work at libraries who can help you hone your search skills as well as find answers to your questions. They also do funny dances with library carts, I hear, which is always worth the time spent at your local library. Jokes aside, considering the number of people who don’t possess home computers and computer & online literacy, well-funded libraries and intelligent, helpful librarians are crucial to the future of information facilitation. Also consider publishing your search results and analyses as a blog post to help others who may have the same question.
4) For humanity’s sake, lower the noise or help verify data.
Blair pointed me to The Economist’s The Data Deluge which simultaneously celebrates and bemoans the exponential increase in data, be it photographic, tabular, scientific or vital-statistical in nature, and how corporations are only beginning to find value in separating the wheat from the chaff. Violation of privacy aside, the greatest threat to signal quality is data hoarding (especially by individuals, taxpayer-funded organizations and publishing houses) and a large amount of noise in the system. Those who do put information out there don’t (want to) curate it, which includes ensuring accuracy and constant updates. In a comment on the aforementioned Economist article, a D. Sherman says it best:
… the vast majority of of “noise” in databases is simply bad data, duly entered and propagated … We put a great deal of effort into collecting more and more data, but comparatively little into weeding out bad data. This implies that the sign[al]-to-noise ratio is only going to deteriorate. Part of the reason for that is that the incentives all favor collecting more data, but do not adequately penalize bad data.
… Members of the database resistance movement who are willing to risk more radical means of spoofing more important databases can readily imagine even more creative (though less legal) methods. When RFID tags and image-recognition tracking of people and vehicles becomes more common, the opportunities and means for injecting noise into the system will multiply exponentially.
The solution is a selective and sophisticated willingness to part with data depending on what the data involves. Not divulging personal information and data hoarding are two different things. While I value my personal privacy and often purposefully give wrong phone numbers and zip codes to websites and salespeople, I will readily part with any scientific, technological or social information that is not classified explicitly as proprietary. Google and Bing are not entitled to my street address but they are to my paper on transtensional folding because Americans paid for it and not Elsevier or Springer.
Another sure-fire way to lower noise is to cut back on content replication. A mature search engine will a) enforce canonical URLs and b) take a scythe to unabashed content scrapers who enjoy high search engine rankings. I’ve lost track of the number of MY blog posts that show up on others’ sites as higher-ranked search hits. (Just because my content is published under a CC-BY-NC-SA license does not mean you are entitled to pilfer it and ignore the non-commercial and share-alike components of the license.) Also, take-down notices only work if you can find a responsive human on the other end to respond, and who has time for that? There has to be an easier way to punish websites and aggregators for outright plagiarism and internet abuse.
Speaking of content replication, here’s an interesting “what-if” article on information copying and machine sentience. I guess there is one benefit to a low signal-to-noise ratio in the network: really dumb Artificial Intelligence, should it emerge.
@geologynews wanted to know where he could find “a list of all earthquakes from 2010 (say, >M5.0+), not just from the past week or month.” At the Incorporated Research Institutions for Seismology (IRIS) Earthquake Browser, of course!
The following map shows all 963 earthquakes between January 1st, 2010 and today.
In two months, a tiny fraction of a percentage of a blink of the geological eye, there were almost a thousand recorded movements of the lithosphere. They nicely outline Earth’s plates and some intra-plate activity: Oceans subducting under continents, the mid-Atlantic rift quietly creating new crust, the furious Pacific Ring of Fire, the East African Rift, India ramming away at Asia and America unraveling at the Basin and Range. The Earth is alive and doing its thing. Earthquakes aren’t oddities, they are the natural norm. Never forget that.
Next up are all earthquakes above Magnitude 5.0 for the same time frame. These make up a third of all earthquakes in the last two months.
The IRIS Earthquake Browser uses the Google base map and interface, so you can zoom in on particular earthquake-hit regions and look at satellite imagery & terrain data along with regular map view.
I urge everyone to donate as much as they can to the victims of the earthquakes in Chile and Haiti, and also ask you to take an objective stance towards why natural disasters happen. As I explained to my physician brother who was concerned about the frequency and severity of recent earthquakes and attendant natural disasters, think of the earth as the human body, i.e. it’s all inter-connected and there is a perfectly plausible reason for all “ailments,” even ones we don’t yet fully understand.
Let’s use Haiti and Chile themselves as examples. Haiti is an impoverished and deforested former French island colony sitting on the steep, clayey soil over an active strike-slip fault which just moved in a catastrophic manner in the lead-up to the rainy and hurricane seasons. I hope to still be alive when the nation is rebuilt and recovers from its ongoing and upcoming physical, emotional and social trauma. The geographic shape of Chile could not have been fashioned more disastrously by God himself. The nation parallels an active subduction zone to the west and a highly-explosive mountain range to the east. When were this earthquake and associated tsunami NOT going to happen? (As it happened half a century before. And how long until the Andes let one loose?) Thankfully, Chilean buildings are more sturdy in build and the earthquake occurred offshore and not directly underfoot as in the case of Haiti. This also highlights the difference between the magnitude and intensity of an earthquake and why a 7.0 in Haiti wreaked more havoc than an 8.8 in Chile. Again, this time around, the generated tsunami did not take as many lives as in 2004.
Each new natural and unnatural disaster definitely weakens our collective will, but it’s not an excuse for brain rot. This is why I’m glad to be alive in the internet age. We use this interconnectedness to give and get help, hope and knowledge. Vive Haiti. Vive Chile.
