"Why do we find ourselves so close to the aftermath of this very strange event, this Big Bang, that has such low entropy? The answer is, we just don't know. The anthropic principle is just not enough to explain this. We really need to think deeply about what could have happened both at the Big Bang and even before the Big Bang. My favorite guess at the answer is that the reason why the universe started out at such a low entropy is the same reason that an egg starts out at low entropy. The classic example of entropy is that you can take an egg and make an omelette. You cannot take an omlette and turn it into an egg. That is because the entropy increases when you mix up the egg to make it into an omelette. Why did the egg start with such a low entropy in the first place? The answer is that it is not alone in the universe. The universe consists of more than just an egg. The egg came from a chicken. It was created by something that had a very low entropy that was part of a bigger system....

Every time you put milk into your coffee and watch it mix and realize that you can't unmix that milk from your coffee, you are learning something profound about the Big Bang, about conditions in the very, very early universe. This is just a giant clue that the real universe has given to us to how...

"Relaxing on an idyllic beach on Grand Cayman Island in the Caribbean, Anthony Aguirre vividly describes the worst natural disaster he can imagine. It is, in fact, probably the worst natural disaster that anyone could imagine. An asteroid impact would be small potatoes compared with this kind of event: a catastrophic encounter with an entire other universe. As an alien cosmos came crashing into ours, its outer boundary would look like a wall racing forward at nearly the speed of light; behind that wall would lie a set of physical laws totally different from ours that would wreck everything they touched in our universe. “If we could see things in ultraslow motion, we’d see a big mirror in the sky rushing toward us because light would be reflected by the wall,” says Aguirre, a youthful physicist at the University of California at Santa Cruz. “After that we wouldn’t see anything—because we’d all be dead.”"

"Only in very serious minds can these conceptions of the US government co-exist: 1. The US government is so hopelessly inefficient and incompetent, that any attempt to deliver government-provided health insurance (or the option thereof) to the uninsured (and some/all of the already-insured) is an unprecedented fool’s pipe dream of a fantasy of a boondoggle with no chance for any positive outcome. Also, socialism. And at a price tag of $1.2 trillion dollars over ten years, there is no way we can afford to chase such fantastical chimera. AND 2. The US government is so remarkably efficient and competent that it can transform (wholesale) Iraqi and Afghan societies (at the same time) and remake those societies into US-friendly, Western-conceived models of good governance, free market economics and liberal democracy all through multi-decade armed occupations. These goals are easily attainable for a government so adept at devising and delivering effective political, economic, social service...

"As even their critics admit, Levitt and Dubner have performed a useful service in drawing greater popular attention to geoengineering. Garden hoses to the sky,however, are not the only approach. Iron fertilization is simpler, cheaper and much more easily testable. Most people are aware that CO2 and temperature are positively correlated in the long historical record but fewer people know that iron dust correlates negatively on the same scale - that is, temperature and CO2 levels are low when iron-dust is high. The graph illustrates. The basic mechanism that appears to drive the association between low temperature, low CO2 and high iron-dust levels is that iron-rich dust sometimes sweeps off the continents into the oceans where it creates a plankton bloom. Phytoplankton take up CO2 in order to grow and as they die and produce fecal matter (I kid you not) carbon sinks to the lower depths or bottom of the ocean where it may remain for 100 to a 1000 or to even to millions of years (in the...

I met some marine microbiologists from Max Planck Institute Bremen at ISMB last summer where we talked about this specifically. They explained a couple of problems with this. Under natural conditions, only a fraction of the CO2 taken up by phytoplankton actually reaches the ocean floor, because grazers normally eat the phytoplankton and bring it back up to the surface. But under...

I got all that from one lunch with people who specialize in marine microbiology and have been thinking specifically about combatting climate change. I wonder if Levitt or Tabarrok have done the equivalent, or if they automatically understand everything because they're economists and thus can do away with the need for expertise (or even data) by the sheer power of their intelligence.
- Ruchira S. Datta
Jim, that doesn't follow. Actually reducing CO2 emissions is much simpler, though not easier, than these geoengineering solutions. The geoengineering solutions only *seem* simple because the complexities of ecology are swept under the rug. Economists of a certain stripe are accustomed to sweeping complexities under the rug (with regard to the economy as well), but in this case it just won't do.
- Ruchira S. Datta
Do you think that's an affliction unique to economists? I see a fair amount of it in other fields too, like computers for example.
- Jim Norris
It seems like we'd have much less insight into the secondary effects of any of these global warming mitigation schemes than we would if we pursued reduction in greenhouse gases in the first place. It seems like a lot of the mitigation strategies just trade off one environmental problem for another.
- Jim Norris
No, it's not unique to economists--in fact I think they caught the attitude from physicists, but the attitude at least seems to work well in physics itself (as opposed to various other fields to which physicists think they can lend their powerful intelligence--see http://arxiv.org/abs...).
- Ruchira S. Datta
Do you think they caught the "pure math" bug and lost touch with empirical reality?

About computers, I think that may be at least a bit different because at least a small number of human intelligences designed the computer in the first place.

I interacted with some mathematical economists when I was doing my (pure math) thesis in game theory. One of them actually told me, "Don't use examples, they just make things more confusing." !!!

I can't stand gratuitous math porn in economics (or CS or any other science). I think a lot of it just serves to make the reader feel dumb and make the author look smarter, even when it has no bearing on reality. But then again I am not a scientist. I just admire them from afar.

Jim, you said "It seems like we'd have much less insight into the secondary effects of any of these global warming mitigation schemes than we would if we pursued reduction in greenhouse gases in the first place. It seems like a lot of the mitigation strategies just trade off one environmental problem for another." and I think that sounds great. The thing that stumps me is the fact that we're increasing our output of greenhouse gases, not decreasing. So, how do we pursue reduction of greenhouse gases?
- Jason Wehmhoener
OK, interesting concept. Then how do we get the industrialized world to stop increasing emissions? Or, maybe we need a more tractable problem: Is it possible to design an experiment that demonstrates the mitigation of secondary effects given a partial or localized reduction in emissions? In other words: do we need the whole world to grow up and get along before we can prove the efficacy...

I'm sure I'll get in trouble for this comment, but I think stopping industrial emissions is like stopping teenage sex.

One day I think we will give up and decide to reduce CO2 by planting forests, increasing...

- Amit Patel
Amit, the reason I had that conversation with those microbiologists in Bremen is because I was interested in developing geoengineering to reduce CO2 myself. I'm all for planting forests, but they take a long time to grow. In this case relying on geoengineering would be like engaging in unsafe sex in 1920, gambling that a birth control pill will be invented before an unplanned pregnancy occurs.
- Ruchira S. Datta
Much simpler than planting forests and waiting for them to grow is stopping deforestation, e.g. for producing beef or biofuels, which no matter how efficient will always be net carbon positive.
- Ruchira S. Datta
Ruchira, that makes complete sense. Unfortunately our agricultural lobbyists have an unhealthy amount of power and work hard to prevent any reduction in support for biofuel or beef production. How can we resist these forces?

Confronted with those who neglect to recognize themselves in our orgies of negation, we offer neither dialogue nor criticism but only our derision. We must negate all banality—in secret.

"Ezra Klein sat down with an insurance industry CEO to try and better understand what’s going on with our health care system. The most interesting part of the conversation (to hear him tell it) was seeing charts that actually assign costs—in dollars—to different units of care (like pills, doctor visits, and lab tests), and then compare those costs to the same units in different countries. He describes the United States column in all the bar charts like “a New York skyscraper that got lost in downtown Des Moines” in comparison to all the other countries. And, looking at the charts, it’s hard not to agree. The takeaway: our health care costs more because we let insurance companies and care providers charge more. In other countries, governments set the rates for different treatments and drugs."

"Football faced a version of this question a hundred years ago, after a series of ugly incidents. In 1905, President Theodore Roosevelt called an emergency summit at the White House, alarmed, as the historian John Sayle Watterson writes, “that the brutality of the prize ring had invaded college football and might end up destroying it.” Columbia University dropped the sport entirely. A professor at the University of Chicago called it a “boy-killing, man-mutilating, money-making, education-prostituting, gladiatorial sport.” In December of 1905, the presidents of twelve prominent colleges met in New York and came within one vote of abolishing the game."

"CSSEmbed, a tool to automatically embed images into CSS files as data URIs. This is a very small, simple tool that reads in a CSS file, identifies the images referenced within, converts them to data URIs, and outputs the resulting style sheet. The newly-created stylesheet is an exact duplicate of the original, complete with comments and indentation intact; the only difference is that all references to image files have been replaced with data URIs. Because it preserves the original formatting of the style sheet, it can be used both on nicely-formatted source code and crunched source code without worry."

"Coming from the house of Michigan-based design firm Jruiter, here is an inner city bike concept that seems to be more about fashion and culture than speed and performance. Designed as a Spartan two-wheeler for short-range urban travel, the city bike features a minimalist design for easy commutation and parking in urban environments. Drawing inspiration from the “hobby horse” and the cafe racer, the bicycle removes basic key components to create a new type of minimal city bike. Integrating 29″ rims, huge big apple tires, a rear hub (planetary internal freewheeling, unicycle through axle) and a single front disc brake, the stripped-down bike is easy to control and allows quick turns while generating huge power from the rear wheel."
