Bad Science

Besides Congressman Akin, who clearly ditched high school biology, my favorite member of the Congressional Science Committee is Dana Rohrabacher (R-CA) who is on record as saying:

“Is there some thought being given to subsidizing the clearing of rainforests in order for some countries to eliminate that production of greenhouse gases? … Or would people be supportive of cutting down older trees in order to plant younger trees as a means to prevent this disaster from happening?”

http://motherboard.vice.com/2012/8/21/congress-s-science-committee-doesn-t-get-science

According to Motherboard, the Congressional Science Committee is responsible for “the entire spectrum of national science interests, from energy, the environment and the atmosphere, civil aviation and nuclear R&D, and space.”

I wish I could say these are actors in a Mel Brooks movie, especially since Congressman Brooks (R-AL) said, in an interview with Science Magazine  that high levels of carbon dioxide means that “plant life grows better, because it is an essential gas for all forms of plant life.”

I’ll let the opportunity for an “essential gas” joke pass.  There’s enough to laugh and weep over in these words from our members of Congress.

The Serious Business of Play

Posted on by

As I worked on the previous post and began to envision a series of articles on imagination, the July-August issue of the Smithsonian Magazine arrived with a piece that fit the theme.  In “Why Play is Serious,” Alison Gopnik, a leading researcher in cognitive development, says play is “a crucial part of what makes all humans so smart.”

Alison Gopnik

Many of us intuitively know that play matters, but Gopnik and her colleagues at UC Berkeley have new theories and research on why it’s so important.  http://www.smithsonianmag.com/science-nature/Let-the-Children-Play-Its-Good-for-Them.html

How is it that very young children learn so much so quickly?  Gopnik’s research focuses on pretending, which she calls “counterfactual” thinking.  She gives the example of Einstein wondering what would happen on a train traveling at the speed of light.

Gopnik found that “Children who were better at pretending could reason better about counterfactuals – they were better at thinking about different possibilities.  And thinking about possibilities plays a crucial role in the latest understanding about how children learn.”

Ms Gopnik is concerned about policymakers who “try to make preschools more like schools.”  In hard times, “frivolous” programs are always the first to go – disciplines like the arts, music and humanities – the very ones that stretch imagination and encourage us to envision new possibilities.

By the time we are adults, we’ve learned how to sideline play in order to get down to business.  Even – or perhaps especially – in the creative realm, it’s no simple matter to let go of goal-oriented behavior when competition in the marketplace is so stiff.  Working for concrete or pre-defined results is the antithesis of the kind of free experimentation that opens up new vistas.

Some sort of strategy is usually needed for us to approach the unselfconscious freedom of children at play, but it doesn’t need to be anything dramatic.  At the end of his life, Joseph Campbell said an hour a day in a quiet room with a favorite book or a journal is enough for us to step into sacred space where the real hero’s journey always takes place.

Simple but never easy.  In a recent post on his own blog, Michael Meade quoted these marvelous lines penned by E.E. Cummings:

“To be nobody-but-yourself — in a world which is doing its best, night and day,
to make you everybody else — means to fight the hardest battle which any
human being can fight; and never stop fighting.”

The fact that the battle is hard is all the more reason why we cannot afford to forget how to play.

Hunting UFO’s and Your Chance to Tweet Outer Space

Tonight at 9:00pm, the National Geographic Channel will present “Chasing UFO’s,” with a team of three investigators checking out reported sightings in Texas, Fresno, and other hotspots of alien activity.

The National Geographic Team – move over Men in Black!

In a recent survey, National Geographic discovered that 80 million Americans – a third of the population – believe in UFO’s.  Seventy-nine percent of us think the government has kept UFO information hidden, and more than half believe there are real Men in Black who threaten people who report sightings.

Aliens grok Geena Davis in “Earth Girls are Easy,” 1988

But wait – there’s more going on tomorrow than just watching other people have all the fun.  There’s something to take our minds off wondering how to land a job as a UFO Chaser.  It’s the Wow Reply Project.

In August, 1977, Jerry Ehman, a researcher at the Ohio State Big Ear radio observatory, spotted a coherent alpha-numeric sequence on a computer printout of signals from deep space.  He grabbed a red pen, circled it, and wrote “Wow!” in the margin.

Tomorrow night, National Geographic gives us the chance to Tweet back to whatever alien intelligence may have tried to contact us.  You can schedule your reply at this link: http://channel.nationalgeographic.com/channel/chasing-ufos/the-wow-reply/.

And in case you’re a bit stuck in figuring what to say, the Geographic has solicited suggestions from several experts, including Stephen Colbert, to help us.  Check out Colbert’s recorded message, which begins, “Greetings intelligent alien life forms.  I am Stephen Colbert, and I come to you with an important message from all the peoples of the earth.  We are not delicious.”

From “The Day the Earth Stood Still,” 1951

It isn’t easy to make up a tweet for space beings.  What can you possibly say?  “Greetings, aliens. I had cheerios for breakfast, how bout you?” See, this is going to take some work, and there isn’t much time, so we better get busy!

What Ancient Bones Tell Us About Being Human

Last week a remarkable show ran on PBS, “The Bones of Turkana,” which documents Richard Leakey’s search for the origin of the human species. Convinced that the Turkana Basin in Kenya is the place where we all began, Leakey, his wife, Meave, and their team have excavated the region around Lake Turkana since the 1960’s.

This documentary, largely narrated by Leakey, gives a real feel for the region and the painstaking work of uncovering our past, but the most interesting questions concern what it means to be human.  Computer simulations picture early hominids who lived hundreds of thousand years apart.  At what stage, at what point in time, did our ancestors become human?  What core attributes distinguish us from other mammals?  In the 1980’s, Leakey founded the Turkana Basin Institute to explore this and related questions.

Language is one key attribute Leakey says, along with walking upright and using tools.  Communication, walking on two legs, and tool use are not  exclusively human traits, so Leakey expands on his nuanced criteria:

“We know birds use tools and chimps and insects and lots of mammals. But to take a block of very hard stone and to take another stone and fashion an object from it, that’s something different. You have to “see within” the stone to know what you’re fashioning before you fashion it. You have to project an idea.  That’s a step that no other tool maker uses.” http://boingboing.net/2012/05/15/bones-of-turkana-meave-and-ri.html

Leakey bases his final core criterion on the 1.6 million year old skeleton he calls, Turkana Boy.  This young person apparently suffered from spinal deformities.  He was not a robust adolescent and could not have warded off predators or hunted on his own.  Leakey identifies the final key human trait as compassion.  This is something he knows about first hand.  Since losing his legs in a plane accident in 1993, Leakey has had to rely on the kindness of others to help him survive and thrive.

PBS has made the entire program available to watch at this link:  http://video.pbs.org/video/2235479708/.  It’s a fascinating account.

Ancient Mayan Newsflash: The World is Not Going to End in December

We can all breathe easier on this score, according to a recent find at Xultan, in northeast Guatemala.  Archeologists discovered a wall in a small room that seems to have functioned as a blackboard for Mayan astronomers.  The 1200 year old calculations represent the oldest known Mayan astronomical tables, suggesting a future at least 6,000 years long.

Courtesty, National Geographic.

“Why would they go into those numbers if the world is going to come to an end this year?” asked Anthony Aveni of Colgate University, an expert on Mayan astronomy.  Aveni and others published their findings Friday, in the journal, Science.

Independent researchers call the find very significant.  The results of Mayan calculations of moon phases and the position of the Sun, Mars, and Venus were known from public monuments, but up until now, the means of calculation were unknown.  Aveni suggests the scribes may have been  “geeks … who just got carried away with doing these kinds of computations and calculations…”

At the end of the year, when we no longer have the the elections to worry about, and all your friends are starting to think of apocalypse, you can tell them about the Mayan geeks, and suggest they chill.

The Secret Life of Pronouns

Posted on by

Who knew that pronouns can predict romantic compatibility, reveal power dynamics, lying, and who will recover from trauma?  James Pennebaker, a psychologist at the University of Texas at Austin has been tracking the truth of pronouns for 20 years.

James Pennebaker

He includes them in the group he calls “function words,” necessary parts of speech that are invisible to us in conversation:  the, this, though, I, and, an, there, that, he, she, where, when.  Pennebaker contrasts these with “content words,” which carry meaning and evoke images in our minds, words like, school, family, life, friends.

In a recent NPR interview, Pennebaker related that he and his students studied couples’ compatibility in the context of speed dating, http://tinyurl.com/7skcgf4.  Computers proved an essential tool for analyzing results, since try as we might, we really don’t hear function words.  By entering both the transcript and the speed dating outcomes, Pennebaker’s team discovered a strong correlation between matching function word usage and the decision to get together after the first meeting.  The computer predicted who would hit it off more accurately than the couples themselves.

This is not because similar people are attracted to each other, Pennebaker says; people can be very different. It’s that when we are around people that we have a genuine interest in, our language subtly shifts.

“When two people are paying close attention, they use language in the same way,” he says. “And it’s one of these things that humans do automatically.  They aren’t aware of it, but if you look closely at their language, count up their use of ‘I, and, the,’… you can see it. It’s right there.”

The other discovery Pennebaker discussed in the interview centers on power dynamics.  When two people with different status or power interact, the subordinate uses “I” much more frequently.  Pennebaker suggests self consciousness is the cause, concern about how we’ll be perceived.

Finally, Pennebaker weighed in on the My Fair Lady question:  if we change our language, do we change?  After 20 years of research, Pennebaker says no.  Change who you are and your language will change, but not vice-versa.

What’s interesting is that several people I respect claim that changing your handwriting changes personality.  Organize your penmanship, for instance, and other aspects of your life will follow.  This suggests the added visceral dimension makes the difference.  Makes you wonder – The rain in Spain falls mainly on the plain.  Probably doesn’t work as well on a keyboard…

People and the Planet: A Report by the Royal Society

Posted on by

On April 26, The Royal Society, the UK’s 350 year old academy of science, released the results of a 21 month study of patterns of population and consumption.  Sir John Sulston, chair of the working group, put it very simply:

“The world now has a very clear choice.  We can choose to address the twin issues of population and consumption.  We can choose to rebalance the use of resources to a more egalitarian pattern of consumption, to reframe our economic values to truly reflect what our consumption means for our planet and to help individuals around the world to make informed and free reproductive choices.  Or we can choose to do nothing and to drift into a downward vortex of economic, socio-political and environmental ills, leading to a more unequal and inhospitable future.”  http://royalsociety.org/news/Royal-Society-calls-for-a-more-equitable-future-for-humanity/

The Society issued a 132 page report that makes several key recommendations  http://royalsociety.org/policy/projects/people-planet/report/:

  1. The international community must bring the 1.3 billion people living on less than $1.25 per day out of absolute poverty, and reduce the inequality that persists in the world today. This will require focused efforts in key policy areas including economic development, education, family planning and health.
  2. The most developed and the emerging economies must stabilise and then reduce material consumption levels through: dramatic improvements in resource use efficiency, including: reducing waste; investment in sustainable resources, technologies and infrastructures; and systematically decoupling economic activity from environmental impact.
  3. Reproductive health and voluntary family planning programmes urgently require political leadership and financial commitment, both nationally and internationally. This is needed to continue the downward trajectory of fertility rates, especially in countries where the unmet need for contraception is high.
  4. Population and the environment should not be considered as two separate issues. Demographic changes, and the influences on them, should be factored into economic and environmental debate and planning at international meetings, such as the Rio+20 Conference on Sustainable Development and subsequent meetings.

Please look at this video clip of Sulston summarizing the findings of the report, which he will present at the United Nations on May 1, ahead of the Rio+20 conference.

Of special interest to me was Sulston’s critique of GDP as the key measure of economic wellbeing for nations.  GDP, he says, drives growth to levels that cannot be sustained.  Michael Meade once observed that unbridled growth in the body is cancer, and unbridled growth in the body politic is a parallel ill.

Growth is such an ingrained measure of wellbeing that re-imagining global socio-economics will not be simple or easy.  One tactic, according to the working group, is to factor in real costs:  what are the real costs of disappearing forests and species?  What is the real cost of water when the study predicts that 1.8 billion people will live with severe water scarcity by 2025?

The issue of water brings to mind my previous post, “Another Regulation Conundrum,” http://wp.me/pYql4-21e, which describes a couple’s 40 year effort to create an self-sustaining and non-polluting homestead.  One of their projects was recycling household “gray water.”  The county building codes have no provision for such experimental ways of doing things, and the couple has racked up large fines and an eviction notice.  In a very real sense, the status quo is the problem.  According to the Royal Society, not only our building codes but the mindset behind them must change or the quality of life for everyone will continue its spiral of decline.

One parting thought:  the study was released on Thursday.  Why haven’t we heard it mentioned on any US media?

Another Regulation Conundrum

Posted on by

My previous post centered on regulations to force bloggers to disclose seemingly small-fry issues, like whether they were comped with an ebook for reviewing independently published authors.

Thursday’s paper ran a story from the New York Times on a more weighty and poignant regulatory issue.  The article, “Marin County battles hippie holdout,” tells of David Lee Hoffman, an entrepreneur of artisan teas, who designed and built 30 structures during the 40 years he lived on a rural hillside.  Inspired by youthful treks through Tibet and Nepal, Hoffman, 67, and his wife, Ratchanee, have tried to create a sustainable, non-polluting, homestead.  In the process, by ignoring repeated notices of violations of county building codes, they racked up $200,000 in fines and have just been ordered to vacate their home until the violations are fixed. The case is now before a judge.  http://www.sacbee.com/2012/04/26/4443307/hippie-askldj-flaksj-dfklaj-sdlfkj.html

The Hoffman homestead contains such fanciful structures as the Worm Palace, a Solar Power Shower Tower, and a moat, which is integral to recycling household water.  One of the county’s chief concerns is their method for disposing of human waste, which uses worm colonies to help turn human waste into humus.  Composting toilets are not legal in Marin.  The county also says it’s worried about an excess of rain, which could flood the moat and send the gray water into nearby creeks.

Hoffman says, “I did what I felt was right.  My love of the planet is greater than my fear of the law.”

***

There’s nothing simple about the regulations that govern our lives, and many of them serve us well.  I like clean water and knowing the content of the food I eat.  I want pure aspirin when I have a headache, and I want to trust the odometer when I shop for a used car.  If I buy a hot dog during a ballgame, I don’t want to have to think , of Upton Sinclair’s, The Jungle.  And I might not want to live downstream from the night soil in the Hoffmans’ garden.

And yet…

Most of us know, in the corners of our awareness, that many of our problems are beyond the capacity of our current institutions.  We know that business as usual is part of the problem.  That regulators do not create solutions.  As Einstein said, “One cannot alter a condition with the same mind that created it in the first place.”

How do we enable people like the Hoffmans, willing to devote their lives to imagining new ways of living?  If we fine and evict people for living their dreams, pretty soon we’re going to run short of dreamers.
