Winter project’s finished – now to enjoy the summer!

Last thanksgiving, inspired by both a friend’s adventures and an article featured on Lifehacker (original here) I had a stroke of inspiration. What I was not aware of was that this particular project would ultimately take me just about 6 months to complete, but having finished it recently I thought I’d share.

The idea behind the whole thing is to take a photograph or painting, crank down the resolution, and what you’re left with is a pixelated version, which you can then lay out as coloured tiles – in this case paint chips – and recreate the photo low-res but at large scale and without lifting a paintbrush.

n1_rect540 The inspiration

Perhaps influenced by the above picture and associated nostalgia, I thought a fedora-clad Bogart might do well. Some searching brought me to this:

Spade3

Which yielded to some mile photoshopping:

Spade4  Spade40 Spade50

And then shrunk to a much smaller resolution:

SpadeFinal FinalBlowUp

With my design set, it was then a quest to get raw materials. A trip raiding the local hardware stores yielded a wide selection of paint swatches, and then began the many-month-long process of cutting out hundreds upon hundreds of squares of colour for tiles. Montreal is cold in winter. There’s no need to go outside.

Splitting the photo into three colour zones let me partition the chips, and then began the selection of tiles to fit the photo. Splitting it into zones of 10x10 helped. For example, the crown of the hat:

7 Zone7BlowUp

And laying out the patterns:

DSC08555

And after another long amount of time, all that was done. Laying them all out, we got:

DSC08557

Note the TV show on in the background. Simultaneous other activities is highly recommended.

A bit more work, and it was glued down, and the final product complete.

DSC08562

Yes, not every colour matches the template. I think that makes it better. Yes, there are gaps. I had to face the reality that I can’t consistently cut squares with a ruler and utility knife. I accepted it and just tried to make sure the gaps ended up randomly dispersed, which I mostly accomplished. And yes, it looks a little eerie in the camera flash, but under ambient light it really worked out well.

And now that sucker hangs on my wall. To those who say I have no artistic talent, I have this to say: only when I don’t have a template.

Science is Hella-cool

It seems the proposal has been put forward to make the SI prefix for 10 to the 27th power “hella-”

I’m a little surprised that this wasn’t named already, I had just assumed that these prefixes were already named up to and far beyond what we would ever need to use. Granted, we haven’t found much use for 10^27 yet; it’s been almost twenty years since the previous (yotta-) was named.

There’s a facebook petition to convince the overlords (Système International – you know they’re the real Illuminati, right?) to add this to their vocabulary. With the force of thousands of high-schoolers and college students, they might just have to concede to the masses.

I can already envision bait-and-switch manoeuvres to lure in unsuspecting young recruits to science.

“Hella-big ridic all-ages edutainment nite! Off the rails, yo!”

It’ll so work.

“Lie to Me”, Temporary Autism and Malcolm Gladwell’s Igon Values

I just finished with Malcolm Gladwell’s Blink: The Power of Thinking Without Thinking. It raises some interesting points, and is certainly an entertaining enough read, but I have to say it’s got my logic gland a little bit inflamed.

logic_glandLocation of the logic gland

Blink deals with the processes that take place in our minds before we’re aware we’ve thought about them (i.e. first impressions). He discusses job interviews, market research, and police (over)reactions, among other things. I’d like to report the take-away message of it all, but to be honest I’m kind of confused what it was supposed to be.

Half the time Gladwell is describes how our first impressions are more correct than we give them credit for, and half the time that they’re terribly, terribly wrong. That’s fine, but without outlining where the distinction lies, it doesn’t help anyone better understand how they might change their thinking on first impressions. The only point that is put forward is that snap judgements are correct if you’re an expert and trained to make objective evaluations, and wrong if you’re a non-expert. Which does all of us non-experts a lot of good.

As an example, Gladwell explains how meticulous analysis of facial expressions, down to specific muscle movements, can carry crucial clues to the person’s intentions. This comes from research by Paul Ekman (Tim Roth on Lie to Me) and the meticulous system he developed, which involves recording facial expressions and breaking down expressions frame-by-frame, giving each one particular, inaccessible codenames.

Those are Action Units 89 and 104 right there, and they tell me Tim Roth had the veal parmigiana for dinner last night

Following this praise for scrutinizing small details to pick out the truth is a complete rebuttal of this methodology. Gladwell goes through how over-analysis of data cost “Blue Team” in the American Army’s Millennium Challenge 2002 war-game. They chose to carefully scrutinize their data, give everything inaccessible acronyms, and break everything down into categories. And this time, that was a bad thing.

My problem with Gladwell’s writing is the same as that recently voiced by Steven Pinker, in response to Gladwell’s most recent book, What the Dog Saw – And Other Adventures. He calls it Gladwell’s Igon value problem, after a particularly damning error (Eigen value, a term any mathematician knows, was the term Gladwell meant to use). Talking about What the Dog Saw, Pinker writes:

The problem with Gladwell’s generalizations about prediction is that he never zeroes in on the essence of a statistical problem and instead overinterprets some of its trappings. For example, in many cases of uncertainty, a decision maker has to act on an observation that may be either a signal from a target or noise from a distractor (a blip on a screen may be a missile or static; a blob on an X-ray may be a tumor or a harmless thickening). Improving the ability of your detection technology to discriminate signals from noise is always a good thing, because it lowers the chance you’ll mistake a target for a distractor or vice versa. But given the technology you have, there is an optimal threshold for a decision, which depends on the relative costs of missing a target and issuing a false alarm. By failing to identify this trade-off, Gladwell bamboozles his readers with pseudoparadoxes about the limitations of pictures and the downside of precise information.

Steven_PinkerWhack! Pinker-slapped!

Gladwell doesn’t get statistics. This prompted Pinker’s response for What the Dog Saw, and was the case in his earlier writings as well. While one scientist’s views, a remarkable event, or a business success story may make for interesting discussion points, it is never the be all and end all. For every example of failed market research, how many times has it been successful? For every time experts identify a forgery, how often are they fooled? A single story makes for a good anecdote, but it is not convincing that it is representative of a phenomenon. The stories he writes on are, after all, remarkable in some way, or else they wouldn’t be worth publishing.

Perhaps most frustrating was his coining of the term “temporary autism” to refer to the lack of comprehension we have of fine details in the first rapid moments of experiencing a novel situation, person, or object. I’ll try to ignore how offensive this is to those afflicted with autism and their loved ones, but seriously, I don’t complain of momentary paraplegia whenever my leg falls asleep. That’s not cool.

Malcolm_GladwellBad, Gladwell, bad!

“Temporary autism” is supposed to represent that we cannot comprehend every detail of a situation and make judgements based on only our (often misled) first impressions. He describes how we need to avoid falling into that trap where the rest of our cognitive processes supposedly shut down. I think he takes this completely the wrong way. People don’t fall into a pathological state (which, if true could be extremely legally problematic) whenever they don’t have enough information. Instead, they operate based on whatever information they have, and then once a complete picture is available, full reasoning and such can kick in. To call everyone potentially irrational and unemotional is pretty damn misanthropic.

Okay, that’s enough for now. I still plan on reading Outliers and What the Dog Saw, but needed to vent about Blink for now. If I have to say one thing, it’s take your Gladwell with a grain of salt.

p.s. If you’ve read Gladwell before (and maybe even if you haven’t), you should read this essay: I Dream in Malcolm Gladwell. Its funny, and helped ease some of my frustrations about this book.

Oh, and here’s Steven Pinker’s Review:

The 5 Second Rule - Expanded

For every rule, there are exceptions. Even something like the 5 second rule, which has saved many a spilled college student's dinner. Check it out:

10second_rule_flowchartSource:Audrey Fukman and Andy Wright

I like to advocate a realistic approach to bacteria in the world around us; while it’s probably not the best idea to eat a pound of soil (for several reasons), contact with non-pristine surfaces doesn’t necessarily make food irreversibly spoiled. In fact, researchers have shown that food may be okay after being left as long as 30 seconds on a cafeteria floor.

There’s lots of places you wouldn’t want to eat food off the ground (hospitals, barnyards, and daycares come to mind) but its possible that we’ve become so accustomed to clean environments, and grown so afraid of all bacteria that we’ve lost perspective on the world around us. Not that long ago the closest thing to a table available was a tree stump or rock. And no one wiped those down with Lysol first.

Tolkien’s Ents Just Became a Little Less Fantastical

green_sea_slugLooking something like a leaf, this sea slug (Elysia chlorotica) has just become the newest organism to breach traditional kingdom boundaries and do something scandalous – photosynthesize. All by itself. Its parents must be so ashamed.

We thought the idea of walking, talking, hobbit-toting, orc-squashing Ents was something wholly in the realm of fantasy. No more. Give it a few hundred million years and we may well see geriatric trees walking the Earth. Whoops, I mean Middle-Earth. Yes, I went there.

What Are You Made Of Indeed, Tiger?

I do my best to avoid celebrity gossip as much as possible, what with the brain-rotting inanity and all. That said, I can’t avoid sharing this one: on the back of a recent (November) newsmagazine, I spotted an ad of America’s newest celebrity philanderer (move over, Jon Gosselin):

Tiger_Tag_Heuer

Oh the sweet, hilarious irony of it all. “What are you made of” indeed. I expect sponsors are tripping over themselves to distance themselves from the Tiger. At least Gillette, another sponsor who builds their image on Tiger’s reputation, has two others to pick up the slack for his poisoned public image. Who were they again?

A thousand taxonomists cried out into the night…

Whoever said cladistics were useless?

Certainly I haven’t.*

An example has just surfaced that shows the importance of taxonomy to this day. Sadly, taxonomists’ vindication may come at the cost of a species of fish, the flapper skate, now recognized as critically-endangered. Classification of this fish as the same species as the related blue skate has allowed the flapper to be fished almost to extinction, and all because of a classification error.

skatePictured: The Flapper Skate. So cute!

So while the fact remains that taxonomy is mostly an outdated field, there might still be some role for the science of natural classification yet. Just not in any of the important sciences.

Knock on wood – LHC might be operational in one week

After more than a year down after various technical problems have kept it from starting, the Large Hadron Collider at CERN in Geneva is planned to be operational next week. The world’s largest experiment may soon be under way.

A week is not much time for anyone to get their tin foil hats on again, but I’m sure we can count on some crazies coming out of the woodwork once they get hold of this news. Bring on the fireworks.

Evolution in the Test Tube – Cool 20-year experiment demonstrates natural selection

or

Richard Lenski is the Awesomest Scientist of All Time. Yes, even more awesome than Doc Brown.

In the ongoing “debate” over evolution going on in the educational system, one claim that the creationists have made is that evolution has not been demonstrated to occur as we watch it. Enter a particularly elegant 20-year study conducted by Dr. Richard Lenski at Michigan State University.

First published a year ago, Lenski’s group has now followed up with a second genomic study on populations of initially citrate-metabolism-deficient bacteria that were cultured in the presence of excess citrate. In these conditions, it was an obvious benefit to any bacterium that would develop the ability to use citrate as an energy and carbon source, as it would then be able to grow faster than the other cells in the culture.

E_coliSeen above: E. coli, not growing

Over tens of thousands of generations, the bacteria did just that, and accumulated beneficial mutations, allowing them to utilize the extra carbon source, and thus gain selective advantage over the bacteria that did not gain these beneficial mutations. This takes incredible foresight, planning, and a little bit of fortuity, but it worked, and 21 years later the research has been published in PNAS and Nature.

While the research is exciting, the enjoyment I truly got associated with this work was not with the scientific publication itself, but Lenski’s response to inquiries of an insidious nature from Conservapedia founder Andrew Schlafly. Click that link to Conservapedia. I dare you. I was sucked into an hour of frustration reading their “balanced alternative to the liberal-slanted Wikipedia” articles, and you should have to endure it as well.

The entirety of Lenski and Schlafly exchange is presented on both the Bad Science blog and RationalWiki. I’ll just place my favourite excerpts here, but I encourage you to read the exchange in its entirety.

Excerpts from Lenski’s response:

I offer this lengthy reply because I am an educator as well as a scientist. It is my sincere hope that some readers might learn something from this exchange, even if you do not.

But perhaps because you did not bother even to read our paper, or perhaps because you aren’t very bright, you seem not to understand that we have the actual, living bacteria that exhibit the properties reported in our paper, including both the ancestral strain used to start this long-term experiment and its evolved citrate-using descendants. In other words, it’s not that we claim to have glimpsed “a unicorn in the garden” – we have a whole population of them living in my lab! [http://en.wikipedia.org/wiki/The_Unicorn_in_the_Garden] And lest you accuse me further of fraud, I do not literally mean that we have unicorns in the lab. Rather, I am making a literary allusion. [http://en.wikipedia.org/wiki/Allusion]

So, will we share the bacteria? Of course we will, with competent scientists. Now, if I was really mean, I might only share the ancestral strain, and let the scientists undertake the 20 years of our experiment. Or if I was only a little bit mean, maybe I’d also send the potentiated bacteria, and let the recipients then repeat the several years of incredibly pain-staking work that my superb doctoral student, Zachary Blount, performed to test some 40 trillion (40,000,000,000,000) cells, which generated 19 additional citrate-using mutants. But I’m a nice guy, at least when treated with some common courtesy, so if a competent scientist asks for them, I would even send a sample of the evolved E. coli that now grows vigorously on citrate.

However, if an incompetent or fraudulent hack (note that I make no reference to any person, as this is strictly a hypothetical scenario, one that I doubt would occur) were to make false or misleading claims about our strains, then I’m confident that some highly qualified scientists would join the fray, examine the strains, and sort out who was right and who was wrong. That’s the way science works.

You may be unable to understand, or unwilling to accept, that evolution occurs. And yet, life evolves! [http://en.wikipedia.org/wiki/E_pur_si_muove] From the content on your website, it is clear that you, like many others, view God as the Creator of the Universe. I respect that view. I find it baffling, however, that someone can worship God as the all-mighty Creator while, at the same time, denying even the possibility (not to mention the overwhelming evidence) that God’s Creation involved evolution. It is as though a person thinks that God must have the same limitations when it comes to creation as a person who is unable to understand, or even attempt to understand, the world in which we live. Isn’t that view insulting to God?

Anyway, Richard Lenski is pretty much my hero.

It’s been a while since I’ve brought out the camera here, so I dragged it around a bit this weekend. Mont Royal is in full swing colour-changing, so makes for good photos these days.

Coffee contains – gasp! – CHEMICALS!!!!!!

Ever wonder just what is in a cup of coffee? At first, you might not want to.

coffeePhoto source: Simone♠13

On the short list, in addition to caffeine, your average brew also contains:

  • Dimethyl disulfide, which contributes to the odour of human waste
  • 2-Ethylphenol, a cockroach pheromone
  • Putrescine, a toxic breakdown product of rancid meat 

While I don’t believe the article writer set out to have this effect, a couple comments indicate he has in fact scared some readers. Of course, it all depends on how you want to take it. Some might be made uneasy at the mention of strange-sounding chemicals with scary qualifiers, and opt to eschew their coffee tomorrow morning. I, however am not about to abandon my sweet, caffeinated nectar of the gods morning cup just yet.

Coffee’s been around for a while now, and (debates about small effects on overall health aside) it’s safe to say that the compounds in coffee, especially at cup-a-day levels, are harmless. This presentation of facts is a good illustration that one shouldn’t be scared of something just because it has chemical names attached to it. The unknown is scary and chemicals particularly intimidating, but any everyday material could be made to sound scarier if placed in the right light.

That cup your coffee’s in? Aluminum and silicon oxides
The table it’s sitting on? Reducing sugar polymers and lignins
The spoon you mixed with? Smelted iron-carbon alloy

You don’t even want to know what sort of nasty phytochemicals are in that banana you were about to eat.

The point being, just because you can name something chemically (and even describe potentially unsavoury places it might be found in nature or industry), that doesn’t make it bad for you. When someone says that a product contains (cue spooky music) chemicals, that person is trying to scare you, usually to buy their product. Case in point:

Note that they never say those chemicals are not present in their product (they are), just that they are present in the competitors. Sneaky bastards.

Anyways, that said, I’m thirsty. I’m off to grab a nice cold glass of dihydrogen monoxide.

Cool Lipdub Video from UQÀM

I might be late to the game with this, as I got the tip-off from CBC, which in turn saw it from CNN, but it’s still cool. As part of the orientation at my neighbouring school, Université de Québec à Montréal (UQÀM), students put together a gigantic, 172-cast single-take uncut lipdub to the Black Eyed Peas’ I Gotta Feeling. And now I have the song stuck in my head. Mazel tov.

The CBC National story said that it had 50 000 views. Now, an hour later, I look and it has 124 000 viewsrefresh the browser – 139 000 views*. Seems it’s not done gathering popularity.

This all reminded me of one I saw earlier this year, that no doubt had influence in inspiring the UQÀM students.

This one was from a school in Germany (Hochschule Furtwangen) and as far as I can tell, pioneered the idea. Their video and accompanying site solicited a whole string of responses at the time - http://universitylipdub.com/response-videos/. Check them out.
