And then the names of things will be changed

George E. P. Box is famous for the quote: “all models are wrong, but some are useful.” […]

In my experience, most models outside of physics are heuristic models. The models are designed as caricatures of reality, and built to be wrong while emphasizing or communicating some interesting point. Nobody intends these models to be better and better approximations of reality, but a toolbox of ideas. Although sometimes people fall for their favorite heuristic models, and start to talk about them as if they are reflecting reality, I think this is usually just a short lived egomania. As such, pointing out that these models are wrong is an obvious statement: nobody intended them to be not wrong. Usually, when somebody actually calls such a model “wrong” they actually mean “it does not properly highlight the point it intended to” or “the point it is highlighting is not of interest to reality”. As such, if somebody says that your heuristic model is wrong, they usually mean that it’s not useful and Box’s defense is of no help.

On the opposite end of the spectrum are abstractions, these sort of models are rigorous mathematical statements about specific types of structures. These models are right and true of their subjects in any reasonable definition of the words. They are as right or true as the statement that there are infinite number of primes; or that in Euclidean geometry, the tree angles of a triangle sum to two right angles. When somebody says that an abstraction is wrong, they mean one of two things:

1. It is mathematically false. […]

2. Or, the structure you are applying it to does not meet the requirements of the abstraction. For example, in general relativity, space is non-Euclidean, so triangles don’t sum to 180 degrees.

I think you are missing out on some ideas on complexity. […] What makes you think that something mathematical is comprehensible? You already invoked one simple form of incomprehension: undecidability in computing. […] As to a belief that the universe is not “mathematical”: well, what else could it possibly be? Many mathematicians define mathematics as the sum-total of all possibility; to say that something isn’t mathematical is tantamount to saying it isn’t possible. Since there is nothing else that it could be, by law of excluded middle, it must be.

Hmmm, no edit-button to correct my post. Some footnotes, then: […]

Box’s quote is kind-of the mirror image of Kolmogorov complexity, which states that a model is useful only if it is smaller than the thing being modelled, and, what’s more, that there are things that cannot be modeled.

According to the U.S. Department of Agriculture, honey bees pollinate 80% of our flowering crops, and are thus essential for the production of 1/3 of our food. […] But for more than 2 million Americans, bees are a dangerous threat. Somewhere between 1% and 7% of human beings are allergic to insect venoms, with their symptoms ranging from mild overreactions to full-blown anaphylactic shock. For those with bee allergies, even the slightest sting can lead to a fight for life. Even more troubling is that, in half of all fatal sting allergy cases, victims had no previous major reactions to venom. Nearly 100 Americans die every year from bee stings. […]

Allergies are defined as ‘hypersensitive immune responses’—or, in colloquial terms, odd moments when our immune systems flip out. Anaphylaxis is the whole-body manifestation of an allergy, which can range from something as minor as hives to sharp drops in blood pressure and even cardiac arrest. You don’t have an allergic reaction the first time you come in contact with an allergen; instead, like with viruses or other potential invaders, your body takes an immunological picture so it can remember the allergen later. This is what is known as the adaptive immune response, and it’s usually a good thing—when you get the chicken pox, for example, your adaptive immune system remembers what the disease looks like, and can find and kill it should you ever be re-exposed. But when it comes to allergies, the adaptive immune system goes too far. The next time it detects allergens, it sends out hordes of IgE antibodies to destroy them. These IgE antibodies wreak havoc in our bodies—through cascading immunological pathways, IgE antibodies cause the release of histamine and other inflammatory compounds and can lead to anaphylaxis.

Even though boys express a wider range of emotions than girls do as infants, boys are typically discouraged from showing their emotions as they grow older due to traditional ideas about masculinity and gender roles. Crying frequency between boys and girls shows little difference until the age of eleven or twelve when girls overtake boys. 

Being told that “big boys don’t cry,” boys are socialized against any display of strong emotion considered inappropriate while crying is specifically targeted as being “feminine” behaviour. There can be enormous culture differences over when and under what circumstances men and women are allowed to cry but men are often expected to be more stoic and unemotional in most situations. […]

Though crying among men seems more tolerated, there are still strong biases against men crying in public. In a 2001 study of undergraduate males in the United States, only 23 percent of males reported crying when feeling helpless as opposed to 58 percent of females with similar sex differences being noted in the United Kingdom and Israel.

According to the Standard Model of particle physics, the universe should be empty. Matter and antimatter, which are identical except for their opposite electric charges, seem to be produced in equal parts during particle interactions and decays. However, matter and antimatter instantly annihilate each other upon contact, and so equal amounts of each would have meant a wholesale annihilation of both shortly after the Big Bang. The existence of galaxies, planets and people illustrates that somehow, a small surplus of matter survived this canceling process. If that hadn’t happened, “the universe would be void,” Schönert said.

The explanation for the survival of some matter may lie in subatomic particles called neutrinos. These particles might have a special property that would give rise to neutrino-less double beta decay.

What pilots spend a lot of time doing is monitoring screens and keying in data. They’ve become, it’s not much of an exaggeration to say, computer operators.

And that, many aviation and automation experts have concluded, is a problem. Overuse of automation erodes pilots’ expertise and dulls their reflexes, leading to what Jan Noyes, an ergonomics expert at Britain’s University of Bristol, terms “a de-skilling of the crew.” […]

Doctors use computers to make diagnoses and to perform surgery. Wall Street bankers use them to assemble and trade financial instruments. Architects use them to design buildings. Attorneys use them in document discovery. And it’s not only professional work that’s being computerized. Thanks to smartphones and other small, affordable computers, we depend on software to carry out many of our everyday routines. We launch apps to aid us in shopping, cooking, socializing, even raising our kids. We follow turn-by-turn GPS instructions. We seek advice from recommendation engines on what to watch, read, and listen to. We call on Google, or Siri, to answer our questions and solve our problems. More and more, at work and at leisure, we’re living our lives inside glass cockpits.

‘Poor are the happy, for they are just what passes.’ –Pessoa

Almost all rich countries are rich because they exploit technological progress. They have moved the bulk of their labor force out of agriculture and into cities, where knowhow can be shared more easily. Their families have fewer children and educate them more intensively, thereby facilitating further technological progress.

Poor countries need to go through a similar change in order to become rich: reduce farm employment, become more urban, have fewer children, and keep those children that they have in school longer. If they do, the doors to prosperity will open. And isn’t that already happening?

Let us compare, for example, Brazil in 2010 with the United Kingdom in 1960. Brazil in 2010 was 84.3% urban; its fertility rate was 1.8 births per woman; its labor force had an average of 7.2 years of schooling; and its university graduates accounted for 5.2% of potential workers. These are better social indicators than the United Kingdom had in 1960. At that time, the UK was 78.4% urban; its fertility rate was 2.7; its labor force had six years of schooling on average, and its university graduates accounted for less than 2% of potential workers.

Brazil is not a unique case: Colombia, Tunisia, Turkey, and Indonesia in 2010 compare favorably to Japan, France, the Netherlands, and Italy, respectively, in 1960. […]

So today’s emerging-market economies should be richer than today’s advanced economies were back then, right?

Wrong – and by a substantial margin. Per capita GDP at constant prices was 140% higher in Britain in 1960 than in Brazil in 2010. It was 80% higher in Japan back then than in Colombia today, 42% higher in old France than in current Tunisia, 250% higher in the old Netherlands than in current Turkey, and 470% higher in old Italy than in current Indonesia.

While most people seem to take this correction in stride, @StealthMountain’s favorites list (which is linked from his bio line) is populated with some of the recipients’ more colorful reactions. You too, dear reader, can laugh at those victims, and their absurd, futile anger towards the machine.

Fishing operations have expanded to virtually all corners of the ocean over the past century. […] How badly are we overfishing the oceans? Are fish populations going to keep shrinking each year — or could they recover? Those are surprisingly contentious questions, and there seem to be a couple of schools of thought here.

The pessimistic view […] is that we may be facing “The End of Fish.” One especially dire 2006 study in Science warned that many commercial ocean fish stocks were on pace to “collapse” by mid-century. […]

Other experts have countered that this view is far too alarmist. […] Overfishing isn’t inevitable. We can fix it.

Both sides make valid points — but the gloomy view is hard to dismiss. […] One reason the debate about overfishing is so contentious is that it’s hard to get a precise read on the state of the world’s marine fisheries.

With every quarterly earnings call, my Twitter feed lights up with jokes about how Amazon continues to grow its revenue and make no profits and how trusting investors continue to rewards the company for it. The apotheosis of that line of thoughts is a quote from Slate’s Matthew Yglesias earlier this year: “Amazon, as best I can tell, is a charitable organization being run by elements of the investment community for the benefit of consumers.”

It’s a great quote, one that got so much play Amazon even featured it in its Annual Letter to Shareholders. But like much of the commentary about Amazon, it’s a misreading of Amazon’s business model.

If Amazon has so many businesses that do make a profit, then why is it still showing quarterly losses, and why has even free cash flow decreased in recent years?

Because Amazon has boundless ambition. It wants to eat global retail.
