Man of the Year 2017


Look at him. He is the Pee-Wee Herman that you thought Pee-Wee Herman looked like after you found out he was a child molester (is that even true? No, I think he just got caught jerking off in public.)

Shkreli ordered jailed after online bounty on Hillary Clinton's hair
Reuters, Sep 2017

For sheer entertainment value alone this guy should get person of the year. He has added more priceless content to the interwebs than any other person (I guess this has been going on for more than a year, but we have to draw the line somewhere).

He raises drug prices so high that he basically kills dozens of people, and has absolutely no remorse. He goes to trial for securities fraud and tweets about how all the people involved are dumbasses, to the chastisement of his lawyer. He goes on trial and they can't even find a jury for him because he is so infamous for being a dirty asshole. His face is that of a sneaky shitbag (just look at him). His name, for christ's sake, is that of the sleeziest scumbag you ever heard of (Shkreli? Just say it out loud). He buys the secret and almost priceless Wu-Tang album for millions of dollars and then threatens to upload it to a torrent site so everyone can have it for free. I think he tried to pick a fight with Raekwon (am I making that up?). He uses twitter better than Donald Trump. (what does that even mean?)

I am definitely missing some things here, but we pause right after this - he puts a bounty on Hillary Clinton's hair, just one strand. You have got to be kidding me. He's serious, he's hilarious, he's preposterous, his moral compass is actually a piece of spin-art made on the boardwalk at the Jersey shore, his conscience is the evil, zero-fucks-epitome of all of us, manifest. He is the perfect child of corrupt capitalism, born fully formed from the head of the Merrill Lynch Bull.

In my series of coward-heroes, he is just the one I've been waiting for. First Jared Loughner, then Julian Assange, now this guy, Martin Shkreli. Man of the year, 2017.

Milk Does a Body


Evolution of Adult Lactose Absorption

Farming, cheese, chewing changed human skull shape
Aug 2017, phys.org

The agricultural revolution put the human genome in the spin cycle of a washing machine. Plants, though fibrous, are easier to chew than animals. So during the thousands of years while we were discovering the magic of seed-sowing, and eating the results of our pre-science experimentation, our bodies (our jaws especially) were changing in response.

At this time in our development, the rate of change for a genome was equal to the rate of change of our culture, and our diet, and so the two were able to influence each other. Nowadays, those rates have changed so that our culture moves faster than the genome - i.e., just this week we saw the first 'living drug' that changes the patient's genome so that it attacks cancer.

Anyway, this is our history:

The largest changes in skull morphology were observed in groups consuming dairy products, suggesting that the effect of agriculture on skull morphology was greatest in populations consuming the softest food (cheese!).
-phys.org

I just have to rant for a moment about arguments for an extreme vegetarian diet. I'm all for being healthy and eating more vegetables and less animals, but to say that it is not natural for us to eat meat or dairy products is preposterous, and this is one of those reasons why. Furthermore, to conjure support for the rational adoption of a 'paleo' diet that mimcs the caveman's diet, because 'that is the diet that we evolved to eat', is also preposterous. A lot has happened since caveman days. Sure, the homo sapien is (?) years old (let's just say on the order of 100,000 years). But since that time, our genome has continued to change. Dairying practices are not 100,000 years old, but more like 10,000. And the impact this had on the homo sapien genome was tremendous.

We are the only mammal that maintains lactase into adulthood - that is a genetic modification that we did to ourselves. Nature did not do that to us; we did it. According to this article above, we also changed the shape of our skulls because of eating cheese.

So, in short, we are  complex creatures. We are more complex than any new diet can encapsulate. I'm not trying to tell anyone what to eat up in here. But I am saying that instead of asserting that there is something wrong with the way we are, and that we should try to be more like the way we were, the "natural way", is to ignore the unfathomably complex and epic journey we have made as a species, and that we should continue to make, as long as we don't all kill each other, and as long as the planet that gave us life doesn't go and kill us all.

Post Script
Here's a paper on lactase persistence, perhaps the greatest story in human culture ever, because it was the inflection point beyond which our culture moves faster than our genes can keep up with.

The Natural Way

Robots eating robots.

'Cyborg' bacteria deliver green fuel source from sunlight
Aug 2017, BBC news

Scientists have created bacteria covered in tiny semiconductors [solar panels] that generate a potential fuel source from sunlight, carbon dioxide and water.

The so-called "cyborg" bugs produce acetic acid [vinegar], a chemical that can then be turned into fuel and plastic.

After combing through old microbiology literature, researchers realised that some bugs have a natural defence to cadmium, mercury or lead that lets them turn the heavy metal into a sulphide which the bacteria express as a tiny, crystal semiconductor on their surfaces.

Dr Kelsey Sakimoto from Harvard University in Massachusetts, US:
"We grow them and we introduce a small amount of cadmium, and naturally they produce cadmium sulphide crystals which then agglomerate on the outsides of their bodies."

They have an efficiency of around 80%, which is four times the level of commercial solar panels, and more than six times the level of chlorophyll.

POST SCRIPT
The Energetically Autonomous Tactical Robot (EATR) was a project by Robotic Technology Inc. (RTI) and Cyclone Power Technologies Inc. to develop a robotic vehicle that could forage for plant biomass to fuel itself, theoretically operating indefinitely. It was being developed as a concept as part of the DARPA military projects for the United States military. [And so it eats dead bodies too]

Off the Grid


Brooklyn's social housing microgrid rewrites relationships with utility companies
Aug 2017, The Guardian

"Microgrids offer something that rooftop solar alone cannot: the ability to leave the grid entirely."

Until the shit goes down.

I am totally into the sentiment here, and I hope this triggers copycats all across the city, and every city. But there is no such thing as an island in the middle of a city; unless of course you're an actual island. After the power went out during Superstorm Sandy, there was not a single hot (powered) outlet in the city that didn't have something plugged into it. There is no way that a community like this, with its off-the-grid resilience, would be spared during an emergency of like proportions. They would be inundated by others trying to charge their phones, and their phone chargers, and their phone charger chargers.

If you want to be able to maintain power in such an emergency where everyone around you does not have it, you're gonna need a lil military to go with that power grid. A security defense system that keeps people out, and maybe even a way to protect the people who live there as they go out into the rest of the city, because people will be pretty pissed that you get power and they don't. This is all part of the glaring hole in prepper mentality - you may be able to prepare for you and your family, but you can't prepare for others. When the shit really goes down, the most dangerous thing you will face is not food shortages but other people.

Unzipf


Zipf's law, top ten most favorite thing on Network Address. New theory ---

Unzipping Zipf's Law: Solution to a century-old linguistic problem
Aug 2017, phys.org

Sander Lestrade, a linguist at Radboud University in The Netherlands, proposes a new solution to this notorious problem in PLOS ONE.

...shows that Zipf's law can be explained by the interaction between the structure of sentences (syntax) and the meaning of words (semantics) in a text.

"In the English language, but also in Dutch, there are only three articles, and tens of thousands of nouns," Lestrade explains. "Since you use an article before almost every noun, articles occur way more often than nouns." But that is not enough to explain Zipf's law. "Within the nouns, you also find big differences. The word 'thing', for example, is much more common than 'submarine', and thus can be used more frequently. But in order to actually occur frequently, a word should not be too general either. If you multiply the differences in meaning within word classes, with the need for every word class, you find a magnificent Zipfian distribution. And this distribution only differs a little from the Zipfian ideal, just like natural language does.
-phys.org

WHAT'S ZIPF

The most frequent word in a language, or in a book, or whatever, will occur approximately twice as often as the second most frequent word, three times as often as the third most frequent word, etc.

(straight from wikipedia, I mean it's all numbers anyway, right?)

For example, in the The Brown University Standard Corpus of Present-Day American English, the word "the" is the most frequently occurring word, and by itself accounts for nearly 7% of all word occurrences (69,971 out of slightly over 1 million). True to Zipf's Law, the second-place word "of" accounts for slightly over 3.5% of words (36,411 occurrences), followed by "and" (28,852). Only 135 vocabulary items are needed to account for half the Brown Corpus.

The same relationship occurs in many other rankings unrelated to language, such as the population ranks of cities in various countries, corporation sizes, income rankings, and so on.

*Zipf's law is referenced in Science Fiction author Robert J. Sawyer's www.wake, when the main character is searching for intelligent life on the web.
http://en.wikipedia.org/wiki/Wake_(Robert_J._Sawyer_novel)

META

There's some other laws meta-physical, like Benford's Law:

In this distribution, the number 1 occurs as the first digit about 30% of the time, while larger numbers occur in that position less frequently, with larger numbers occurring less often: 9 as the first digit less than 5% of the time. This distribution of first digits is the same as the widths of gridlines on a logarithmic scale.

Physicists eye neural fly data, find formula for Zipf's law
August 2014, phys.org

mathematical models, which demonstrate how Zipf's law naturally arises when a sufficient number of units react to a hidden variable in a system.

"If a system has some hidden variable, and many units, such as 40 or 50 neurons, are adapted and responding to the variable, then Zipf's law will kick in."

"We showed mathematically that the system becomes Zipfian when you're recording the activity of many units, such as neurons, and all of the units are responding to the same variable".

Eyes on the Street


Computer 'anthropologists' study global fashion
Aug 2017, phys.org

What is the world wearing?

These scientists are using a deep learning object recognition program to discover visual patterns in clothing and fashion across millions of images of people worldwide and over a period of many years. They detected attributes like color, sleeve length, presence of glasses or hats, etc. (They end up filtering for only waist up photos). They ask questions such as, "How is the frequency of scarf use in the US changing over time?" or "For a given city, such as Los Angeles, what styles are most characteristic of that city."

The objective of this research is ultimately to "provide a look into cultural, social and economic factors that shape societies and provides insights into civilization."

Dashed lines mark Labor Day. Who said Americans don't like conformity?

via Cornell University: StreetStyle: Exploring world-wide clothing styles from millions of photos. arXiv. arxiv.org/abs/1706.01869

I imagined that stuff like this is already happening all over the place, in all kinds of other fields, and being integrated into global policy decisions and bottom-line business calls alike. But, this is not the case; this is still just the beginning. One thing I caught from this, some digital era common sense - Google Trends results for "scarves" peak right before they do on Instagram, because, presumably, people are searching for the thing, then they buy it, then they take pictures of themselves wearing it.

These are the real people, not the algorithms, that analyze and predict the world of fashion:

Believability Likability Falliblity


Why humans find faulty robots more likeable
Aug 2017, phys.org

If you've never watched the robots from Boston Dynamics get pushed over while they try to stand, you really should. (just search robot fail videos). If you've never thought, aw man, I feel really bad for that guy, then you should watch definitely watch it. Because you know, one day when a real robot-looking robot is taking care of your feeble parents, or you, you're gonna want to like that robot. And as it turns out, watching something struggle, whether it's a robot or a bug, or ^this kid trying eat cereal, when you watch someone mess up, it makes you like them more.

Says science:

"...participants took a significantly stronger liking to the faulty robot than the robot that interacted flawlessly." ... This finding confirms the Pratfall Effect, which states that people's attractiveness increases when they make a mistake," says Nicole Mirnig, PhD candidate at the Center for Human-Computer Interaction, University of Salzburg, Austria. -phys.org
