You Call this Progress?

One of the prevailing narratives of our time is that we are innovating our way into the future at break-neck speed. It’s just dizzying how quickly the world around us is changing. Technology is this juggernaut that gets ever bigger, ever faster, and all we need to do is hold on for the wild ride into the infinitely cool. Problems get solved faster than we can blink.

But I’m going to claim that this is an old, outdated narrative. I think we have a tendency to latch onto a story of humanity that we find appealing or flattering, and stick with it long past its expiration date. Many readers at this point, in fact, may think that it’s sheer lunacy for me to challenge such an obvious truth about the world we live in. Perhaps this will encourage said souls to read on—eager to witness a spectacular failure as I attempt to pull off this seemingly impossible stunt.

The (slightly overstated) claim is that no major new inventions have come to bear in my 45-year lifespan. The 45 years prior, however, were chock-full of monumental breakthroughs.

Programmed to Ignore?

640px-CognitiveFunctionsI started Do the Math in 2011 as a way to reach a larger audience than a handful of students every year or two in an energy course at UCSD. I had (and still have) deep concerns about the assumptions we make as a society based on our fossil fuel trajectory over the last century or so. Trying to steer policy from the top seemed a losing proposition: feckless politicians hew to their constituents’ desires via a mechanism we call democracy, so why not try to get people on board directly?

I never imagined creating a blog that would get millions of pageviews, although this by itself falls well short of having an impact on a grand scale. But I figured I owed it to myself to reach as many as I might. What I have found is that a select few seem to share my concerns. And some vocal contributors to comments strongly disagree that we need to worry (why then make the seemingly wasted effort to respond to—in their eyes—doomsaying kooks if in fact we need not be concerned?). But most people simply don’t care enough to tune in. They’ve learned to ignore prognostications of any flavor, perhaps. Lately, even fewer people are entertaining ideas of resource limits owing to increased global oil production (led almost entirely by U.S. shale oil) and a recovering economy.

But I think there is something more fundamental going on here. I think we’re dealing with personality traits cooked into human nature. Are we capable of mitigating a far-off potential calamity via proactive efforts decades ahead of a putative crisis? In this post, I’ll use some survey data suggesting that we may be in trouble.

Okay: Three Question Survey for DtM Readers

I should have done it right the first time.  I now realize that I’m hungry for a tiny bit more information in relation to personality type.  I have had almost 500 responses to the previous query (see previous post, below).  The results are fascinating.  I have added two quick questions that will give me a fair bit of insight into some key systematic issues.

Even if you have answered the poll already, I would appreciate a quick moment of your time to answer two additional questions (click here).  It requires very little time: especially if you responded to the first survey request.

If you did not respond to the first survey, please do this one.

Instructions appear on the survey page for how to determine your Myers-Briggs type, if you do not already know it.  Thanks for your patience, and look for a post in mid-April with the jaw-dropping results.

One-question Survey for DtM Readers

I have a new post written up, but thought that before I release it I should get some delicious new data.

To that end, please take this single-question bare-bones survey (link decommissioned; see this post) about your personality type.  There are sixteen choices in a drop-down menu according to the Myers-Briggs personality type indicator.  If you do not already know your type, you can find free online versions.  While I have no particular affinity for this specific one, it may be good for the sake of uniformity that you go take this one.  It’s 72 yes/no questions (should take 5–10 minutes).

Just remember to be honest and answer for the person you are, rather than the person you may aspire to be (if different).

And don’t forget in your excitement to indicate the outcome on my lighting-fast survey (link decommissioned; new survey here).

I’ll let you know what it’s all about shortly.


Tuning in on Noise?

xkcd-904It’s a bit off-topic for the series, but I can’t even go to Google now without being reminded of the World Cup and soccer this, soccer that. (Apologies to non-Americans who know the sport as football—but don’t get me started on football!) I have often wondered: given characteristic low score values, is soccer anything more than Poisson noise? When discussing this with colleagues, one pointed me to this XKCD comic, reproduced at right.

Any random process that produces discrete events in some time interval, with uniform probability per unit time follows a Poisson distribution. When the number of events becomes large, the distribution tends toward a Gaussian (normal) distribution.

My thesis is that soccer is an amalgam of random processes whose net effect produces rare events—those more-or-less unpredictable events spread more-or-less uniformly in time. Whether a good or bad bounce off the bar, a goal keeper who may or may not prevent a goal, a referee who may or may not see an illegal action, a pass that may or may not be intercepted, and on and on: the game is full of random, unpredictable events. So I expect soccer to behave similarly to a Poisson process and follow a Poisson distribution. By extension, I will claim that the attention devoted to the World Cup is founded on flimsy numerology and might even be called a tremendous waste of time and money.

Normally I allow comments on Do the Math for ten days after each post. I’ve tackled some controversial topics and stirred up emotional responses. Yet I predict that the outrage generated by my insinuation that watching soccer is a waste of time will absolutely dwarf the reactions to my saying that we may not be looking at a space-faring future, or that indeed we may face collapse of civilization. To the extent that this (untested) prediction is true, it would seem that soccer is more important than the fate of the world, in the eyes of many. Scary, if true. [After reconsideration, I enabled comments, but I won't have time to vet and respond with my usual level of attention.]

But getting back to soccer numerology, my question becomes: given a final score (which is taken to be the ultimate “truth” of the match) how likely is it that the victor is actually a better team?

Plans to Put PV to Pasture?

PV out to pasture?A colleague pointed me toward an article in the LA Times last week, which lays out a plan to remove financial incentives legally bestowed on solar photovoltaics (PV) to the detriment of utility power companies. The plan is spearheaded by the Koch brothers and their political action group, Americans for Prosperity.

In summary, they target two laws that give a big boost to solar: net metering, and renewable mandates. Both impart crucial advantages to solar installations that can change the economics by a large factor.

The Already-Written Future?

thumbnail from NYT

As a rejoinder to my piece a couple weeks ago (not really), the New York Times published an article on population growth, and why we need not worry. The problem—and solution—is all in our head.  The bottom line was that we have always transformed our ecosystem to provide what we need, and in so doing have pushed the carrying capacity along with our growing population. In fact, the author says, “there really is no such thing as a human carrying capacity.” And he goes on to ask, “why is it that highly trained natural scientists don’t understand this?”

Clearly there is a misunderstanding, but I’ll side with the natural scientists, naturally. The succinct answer is that natural scientists are not comfortable with ruthless extrapolation of past trends.

The Real Population Problem

Sometimes considered a taboo subject, the issue of population runs as an undercurrent in virtually all discussions of modern challenges. Naturally, resource use, environmental pressures, climate change, food and water supply, and the health of the world’s fish and wildlife populations would all be non-issues if Earth enjoyed a human population of 100 million or less.

The subject is taboo for a few reasons. The suggestion that a smaller number would be nice begs the question of who we should eliminate, and who gets to decide such things. Also, the vast majority of people bring children into the world, and perhaps feel a personal sting when it is implied that such actions are part of the problem. I myself come from a long line of breeders, and perhaps you do too.

Recently, participating in a panel discussion in front of a room full of physics educators, I made the simple statement that “surplus energy grows babies.” This is motivated by my recognition that population growth bent upwards when widespread use of coal ushered in the Industrial Revolution and bent again when fossil fuels entered global agriculture in a big way during the Green Revolution. These are really just facets of the broader Fossil Fuel Revolution. I was challenged by a member of the audience with the glaringly obvious statement that population growth rates subside in energy-rich nations—the so-called demographic transition. How do these sentiments square against one another?

So in the spirit of looking at the numbers, let’s explore in particular various connections between population and energy. In the process I will expose the United States, rather than Africa, for instance, as the real problem when it comes to population growth.

Crippling Intellects

Star Trek brainiac

People can be individually smart and collectively dumb. Or some may argue that people can be individually dumb yet collectively smart. When it comes to plotting a future path, I think we often get the worst of both worlds. In this post, I’ll look at the role that mental horsepower plays in our societal narratives, for better or for worse. We’ll explore two aspects to the problem: people who are so smart that they have dumb ideas; and smart people who are held captive by the manufactured “dumb” of society.

A word of warning: “smart” and “dumb” are loaded words, and even impolite. We place so much value on intelligence in our society that being called smart can make a person’s day, while being called dumb can cut to the core. We’re very sensitive to people’s perceptions of our intellectual standing, and some of the choicest insecurities are laid upon this foundation. I use “smart” and “dumb” as blunt instruments in this post, so if you’re particularly touchy on the topic, either steel yourself or skip the post and call it the smartest thing you did all day.

Let me preface what I am about to say by the disclaimer that most of this is conjecture. I have little data, relying instead on hunches about what makes people tick based on personal observations.

One other disclaimer: this isn’t a post whose veiled message is how smart I am. I might once have thought so, but then I met bona-fide geniuses when I was in grad school at Caltech. Fortunately, I was mature enough at that point for it not to cause a crisis of confidence or identity, and rather enjoyed the window I had into the off-scale brilliance of some individuals. So let’s go ahead and put me in the dumb box so we can move on to what I want to say.

Survey the People

The futuristic survey (covered in last post) has attracted about 1300 respondents, 900 from DtM, 300 from the Energy Bulletin (now, and a smattering from other places.

I will ultimately be sharing the results, but the habitual readers of the aforementioned sites are perhaps not representative of the population at large.

Thus I would like your help in pushing this out to a broader population.  See if you can get your friends and family members to take the survey, and perhaps even pass the link on to their friends, etc.  I’ve never done this sort of thing before, so do not know what to expect.  But let’s give it a try, yeah?

Here’s the link you want to pass on in whatever form (paste into e-mail, Twitter, link on FaceBook, whatever works):

Thanks for your help—should be very interesting.
