Anthropologetic

Author of “Hungry City” Carolyn Steel gives TED.com talk on how food shapes the world we live in.

“A third of the annual grain crop gets fed to animals, rather than to us human animals, and given that it takes ten times as much grain to feed a human if it’s passed through an animal first, that’s not a very efficient way of feeding us…”

This is just a quick quote from Carolyn Steel’s TED talk on the history of how food has shaped our cities.  Being a New York City resident it’s impossible not to notice the amount of food wasted (at one point in the talk she notes that currently in America one half of all food produced it thrown away in America) or the monumental amount of food available to purchase, the whole of which obviously could never be produced in the amount of area given in the greater five-boro area.

It’s a quick video, rounding off at about the 15 minute mark, and Carolyn is clearly knowledgeable about not only the current state of food but the history of it’s effect on the layouts and cultures of larger metropolitan areas (which can be connected to her other profession, which is architecture). She ties in historical data with solutions to coexisting agriculture with urban areas and presses the concept of local farmers markets that bring in endemically grown produce, meats and dairy.

The main point of the talk is to stress humankind’s interrelated relationship with the planet and the food we take from it which sustains us and in effect keeps us connected to the natural world we live in.  Anyone interested in the growing problem of and questions arising from the overproduction/consumption/waste of food will enjoy this presentation.  You can also always visit the TED main site and view the talk there: How Food Affects Our Cities.

One last quote from Carolyn; “And when you think, that 80% of global trade in food now is controlled by just five multinational corporations, it’s a grim picture.”

Things We Forget About the Sun
After reading while laying out on my roof in Brooklyn last week, I quickly rediscovered why I enjoy long sleeves in the summer so much.  It also occurred to me that there are many things about the sun we take for granted in our day to day lives (and on a larger scale, the natural world and universe in general, especially those of us in cities). Here are some of the finer, and to me more interesting points that came to mind as I applied numerous coats of aloe to my poor, U-V ray ravaged epidermus (as you read on, it’s obvious I paid attention in basic high school science courses, usually).

The light from the sun takes approximately 8 minutes to reach the earth and travels a distance of 92,955,820 miles to get here, and even at that distance little more than an hour outside peak mid-day sun cycle, and it is capable of inflicting 2nd degree burns on unprotected skin (see picture above).  It took me several days to heal from this burn, and I suspect staying out there any longer would have left me cracked and peeling.  The odds of being light skinned like myself and getting skin cancer from sun damage is 1 in 50 in America and each year almost 70,000 new cases of melanoma are reported in the United states alone. 
Carrying on with the good news, the sun is also to blame for heat stroke and heat exhaustion, both of which were factors in the Chicago heat wave in 1995 that claimed an estimated approximatley 700 peoples lives (the sun did not act alone here however, much of this was due to the layer of thick smog and pollution blanketing Chicago and acting as a gigantic incubator for the city, trapping in the heat for days not allowing the city to cool off even at night).



My personal favorite.  We can’t look at the sun.  It is constantly in our sky during the daytime hours (barring any atmospheric disturbances) and is the sole reason we exist on this planet, but we are constantly avoiding eye contact with it. Look at it even for a brief time, and the U-V ray damage to your eyes can leave you with irreperable retina damage and burns to the eyes. Correspondinly,  sunglasses are a 2.9 billion dollar industry. 


The sheer size and magnitude of the sun is almost incomprehensible. Being such a vast distance away (with currently space travel technology it would take 160 years to reach the sun) and at such great size (333,000 times the mass of the Earth and 99% of all the mass in our solar system, if hollow it could fit almost a million earths inside of it) and extreme heat (11,000 degrees fahrenheit on the surface) it remains the single most important aspect of our solar system, allowing photosynthesis to take place on Earth almost 3 billion years ago from crude cyanobacteria which lead to the creation of ozone, atmosophere and the air we breath today.

Cars with tinted windows, windows shades, sun screen (because you can’t go out in the summer without having to “protect” yourself from the sun), air conditioners, pools, hats with brims, you name it, all conceived to cope with our lives with the sun.  The point isn’t that the sun is evil, but that with just a little inspection it’s clear the universe was not made specifically to be a gift for humans at all, and as such it is clear why so many cultures invented myths and religions (and the new religions, consumerism and entertainment media) to take their minds off of a world that so obviously didn’t want them around if it could help it ( maybe I have been reading too much Vonnegut latley). Still, the universe remains not a place to fear or drive people to irrational, illogical beliefs, but something to inspire awe and wonder at such a complex, endlessly interesting existence that we have the good fortune of all species to be able to sit and reflect upon.  Now with that, I am going to get off this computer and get some sun.  I’ll leave you with some beautiful images of the sun from The Big Picture blog on boston.com, enjoy, wear sunscreen.

Elaine Morgan: Did we evolve from aquatic apes?

The long held theory for human evolution goes something similar to: our ancestors stood up, (possibly to gather fruit from bushes, or to have freed their hands to carry food or babies), walked out of the forests into the savannah where our legs then lengthened making us supreme distance runners as we lost almost all of our hair to keep us cool in the open grasslands of Eastern Equatorial Africa.

But recently, more and more proponents of an alternate theory, the theory of a semi-aquatic ancestor to humans, are speaking out, including; philosopher/darwinist Dan Dannett, Naturalist/Anthropologist Sir David Attenborough, and Zoologist Desmond Morris.

However possibly the biggest bulldog of the theory is most likely it’s shortest.  Elaine Morgan a writer, feminist, scientific theorist and octagenarian, presents here in this Ted.com video, and whith humor and ease expounds not only on the finer points of her theory, but also on the nature of science and the politics that shape it.

Some of the finer points of a semi-aquatic ancestry: Elaine begins by noting that at the paleontological level more and more digging at early hominin sites is bringing up fossils from that time period not of savannah wildlife, but plants and animals common to aquatic habitats.  On the phenotypic front (or physical. A phenotype is a physical manifestation of a gene. I.E. eye color, hair, number of limbs and so forth), Elaine makes note that every mammal that is alive and hairless today had an ancestor that was conditioned for the water (elephants, hippopotamus, manatee and dolphins are all mentioned). Furthermore humans, unlike any other apes, have a layer of fat under their skin, which is shared in common with other aquatic mammals like seals and whales (also humans as we have all seen can grow momumentally obese, which is physically impossible for any of the other great apes to do, but the build up of blubber in aquatic mammals is a common feature). She goes further to say that a prime factor in human speech is our capability to consciously control our breath, and the only other animals alive that are capable of that same feat are the diving mammals (whales, dolphins, seals) and diving birds (penguins, puffins).

Going on, she points out that though the other great apes can walk upright for short periods of time, all of them always do whenever walking in water. Below is a beautiful, short clip from Life of Mammals with David Attenborough.  The 5min clip has Attenborough walking side by side in marshy water with chimpanzees and offers a candid, startlingly convincing view of what our early beginnings may have been like.

David Attenborough: Chimps Walking Upright (Of course, Attenborough’s explanation will do much more justice than I ever could, this clip works perfectly as a compliment to Elaine Morgans talk and is worth watching in itself).

The talk ends discussing the politics of chance in science.  The aquatic-ape theory has been shut out of academia and schools of scientific theory by long established heads of the field for much longer than the 30 years that Elaine Morgan has been working on it, and brings to light the often times over political, close minded thinking so characterstic of fundamental dogma that is more closely associated with religion, rearing it’s head in the hall of objective thought (she likens it to a priesthood, and quickly makes reference to Richard Dawkins and his suggestion that the best way to treat a priesthood is to refuse to give it all the excessive reverence it’s been trained to recieve and learn to rock the boat and make some noise).

Her broader message is that science isn’t decided via headcount or popularity contest, but by facts and evidence.  Science is a constantly mutable, changing element itself, and history has shown us that it has been and will continue to be so indefinitely.  There is no ruling body of science that exists outside of the burden of proof and evidence, and everything is up for review (Stephen Jay Gould would famously rerun experiments that he found to give slighted racist results in the field of Anthropology, and would routinely retest and correct the tampered data).  Whether Elaine Morgan is correct is and she would agree should be up for debate, but whether it deserves the chance to be so, should not be.

(Excuse the long winded post, but as an Anthropology major this warranted a bit of explanation and time. Enjoy the video(s)).

The Periodic Table of Videos http://www.periodicvideos.com/

This is a website I came across from The University of Nottingham which simply displays the Period Table on screen and links every element to a youtube video (each about 3 minutes long) with one of the resident staff from the Univeristy giving a simple, concise explanation, history and demonstration of each element.

The posted video above is an example from the site for the element Phosphorus (symbol P, atomic number 15).

Each of the members has their own specialty background in various fields of chemisty. The videos as well as the experts are pretty entertaining and easy to access, (for those of us who may not have been the best chem students in highschool) as well as quick, which helps, seeing as how there are 117 elements to get through, each one present on the site for you to explore or discover.

Refreshingly the presenters also seem to be younger (with the exception of one of the professors, who sports a mad scientist meets Phil Specter look, check out his tie, outstanding!). Passionate, charismatic scientists are always welcome in helping the public find an appreciation for the sciences, especially in helping younger scientists-to-be find role models who are closer to their own age group and easier to identify with (needless to say no offense to the great E.O. Wilsons and the James Watsons, who remain invaluable to our understanding of the world around us and will for generations to come).

This is not only fun for the casual lover of science, but for teachers and professors it becomes an easy to access effective resource to offer students who may benefit from having a source to reference when studying while outside of school.  Younger generations will be and are increasingly reliant on the internet as a source of media, news and social interaction, but it has been slow to be picked up as a resource for learning especially in public schools.  Libraries close, but the internet is a 24 hour operation and is a much more accessible, quick source of information and a powerful resource that most younger people are already proficient with. Why not teach children it’s virtues as well as it’s vices (bottom line: the internet should never be approached the way midwest sex education is).

This website is a fantastic example of how the internet can and should be used not only as a source of entertainment, but as a phenomenal tool for the pursuit of education, and when it is as its best, hopefully both.

"Darwin In Kansas" by: Salman Rushdie

This is a short essay written in September, 1999 by Salman Rushdie (author of ‘Midnights Children’ and ‘The Satanic Verses’) on the unsettling lack of acceptance of Charles Darwins theory of evolution by natural selection published in 1859 (also independtly concieved but never published by Alfred Russel Wallace a friend and contemporary of Darwin’s) especially in the American Midwest where it had at the time been taken out of the Kansas school stystems science curriculum in favor of creationism.  Keep in mind this is before intelligent design was invented which further complicates the problem of educating people about the natural world from an objective non-superstitious point of view (furthermore evolution is now widely if not entirely accepted (and observable) by the scientific community and most of the civilized world).  Before I go on too long, here is Salmans short essay. Enjoy

“In This Movie, Toto, We Can’t Go Home Again

Many years ago, in the city of Cochin in South India, I found myself attending the World Understanding Day of the local Rotary Club. The featured speaker was an anti-evolution American creationist, a certain Duane T. Gish, who came armed with a slide show designed to prove, as I recall, that the chief reason for the malaise of Today’s Youth was the propagation, by the world’s school systems, of the pernicious teachings of poor old Charles Darwin.

Today’s Youth was being taught that it was descended from monkeys! Consequently, and understandably, it had become alienated from society, and depressed. The rest — its drift, its criminality, its promiscuity, its drug abuse — inevitably followed.

I was interested to note that a few minutes into the lecture the habitually courteous Indian audience simply stopped listening. The hum of conversation in the room gradually rose until the speaker was all but drowned out. Not that this stopped Duane. Like a dinosaur who hasn’t noticed he’s extinct, he just went bellowing on.

This summer, however, Mr. Gish’s lizardy kind will have received cheering news. The Kansas Board of Education’s decision to delete evolution from the state’s recommended curriculum and from its standardized tests is, in itself, powerful evidence against the veracity of Darwin’s great theory. If Charles Darwin were able to visit Kansas in 1999 he would be obliged to concede that here was living proof that natural selection doesn’t always work, that the unfittest sometimes survive and that the human race is therefore actually capable of evolving backward toward, rather than away from, those youth-depressing apes.

Nor is Darwin the only casualty. The Big Bang apparently didn’t happen in the Kansas area, either; or, at least, it’s just one of the available theories. Thus in one pan of the scales we now have General Relativity, the Hubble telescope and all the imperfect but painstakingly accumulated learning of the human race; and, in the other, the Book of Genesis. In Kansas, the scales balance.

Good teachers, it must be said, are appalled by their state board’s decision. But respected professors publicly concede that it’s going on everywhere and the creationists are winning. In Alabama, for example, a sticker on textbooks hilariously suggests that since no one was present when life first appeared on earth, we can’t ever know the facts. Seems you just had to be there.

Or, not so hilariously. This stuff would be funny if it weren’t so unfunny. American fundamentalists may be pleased to know that elsewhere in the world — Karachi, Pakistan, for example — the blinkered literalists of another faith have been known to come into university classes armed to the teeth and to threaten lecturers with instant death if they should deviate from the strict Quranic view of science (or anything else). Might it be that America’s notorious gun culture will now also take up arms against knowledge itself?

Nor should the rest of us feel too smug. The war against religious obscurantism, a war many people believe had been won long ago, is breaking out all over, with ever greater force. All sorts of gobbledygook are back in style. The pull of stupidity grows everywhere more powerful.

Meanwhile, slowly, beautifully, the search for knowledge continues. Ironically, in the whole history of the sciences, there has never been so rich or revolutionary a golden age. Big science is unlocking the universe, tiny science is solving the riddles of life. And, yes, the new knowledge brings with it new moral problems, but the old ignorances are not going to help us solve these.

One of the beauties of learning is that it admits its provisionality, its imperfections. This scholarly scrupulousness, this willingness to admit that even the most well-supported of theories is still a theory, is now being exploited by the unscrupulous. But that we do not know everything does not mean we know nothing. Not all theories are of equal weight. The moon, even the moon over Kansas, is not made of green cheese.

If the over-abundant new knowledge of the modern age is, let’s say, a tornado, then Oz is the extraordinary, Technicolored new world in which it has landed us, the world from which — life not being a movie — there is no way home. In the immortal words of Dorothy Gale, “Toto, something tells me we’re not in Kansas any more.”

To which one can only add: thank goodness, baby, and amen.”

From “Step Across This Line” a collection of non-fiction by Salman Rushdie, given to me by Mendeley Wells.

Like Stephen Jay Gould and David Attenborough, Neil Degrasse Tyson is one of the great communicators of science to the public.  If you weren’t familiar with him from his many spots on The Colbert Report or NovaScienceNOW which he hosts for PBS, he is an astrophysicist from New York City who runs the Hayden Planetarium at the American Museum of Natural History in Manhattan and is a rumored candidate to be the next head of NASA.  That being said.

In this short clip entitled “Stupid Design”, Tyson speaks about not only all of the things in the universe that want to kill you (meteors, volcanoes, radiation, malevolent microbes, and so forth) but some of the imperfections in nature that prove no sentient designer could have or logically would have come up with. Tyson makes a solid argument for some ontological humility, but not just to scare the audience, also as a reminder that what we really understand is still vastly limited, and that it is very clear what we do have is precious and how we have been thinking about it is a little megalomaniacal. (to put it lightly).

The idea is that the more we understand about the natural world, the more we can begin to understand out place within it.  The size and violent temperment of the universe doesn’t need to be terrifying, it can equally be awe-inspiring.  There is a reason once a month Conan O’Brien has Jack Hannah or Jeff Corwin on the show with a cavalcade of animals, people never lose that natural curosity for all things well, natural.

The milky way is on a crash course with the andromeda galaxy, the sun will go red giant and engulf the earth in 5 billion years, and oh yeah, who would put a theme park next to a waste management facility (you’ll have to watch the end of the video to understand that one).

I hope that this video impresses upon you that the stars that matter don’t have Academy Awards, enjoy the clip.

Something I will talk about quite a bit is the rise of global robotics. With japans rapidly aging retired community and lack of a young workforce, their progress has been fastest out of necessity for labor. Many human themed robots like Hondas ASIMO have been publicized and are truly amazing.  I think however the use of natures playbook rather than just what we have as humans is hands down the smarter approach, and this is a good example.

The video here is from newscientist.com

The robotic “rat” in this video has visual sensors but also whiskers that move back and forth and act as sensors to help the rat establish and navigate it’s environment.  This kind of sensory perception gives this particular robot an advantage in an area where light is unavailable rendering typical vision pretty much useless.  When you realize that other organisms in nature have to navigate the same world we do, but do so in a myriad of variations (bees see in infa-red, bats and dolphins independently evolved echolocation, sharks and rays sense other animals with electric sensors near their snouts, this list goes on) the possibilities for robotics becomes a much broader interesting field than just trying to create human-like robots.

Now as for robots taking over the world, that is another story…

Axolotls (famous for their text book example of neotony or becoming sexually mature but never fully physically mature) can also regenerate lost limbs, something that biomedical engineering has been looking into for some time now, and is inching ever closer as stem cell research has been given the green light.

Answers to medical problems will be found in nature, and evolution will be the greatest teacher the human species ever had.

The article is from sciencenews.org, check it out

The late evolutionary biologist Stephen Jay Gould speaks about the lack of perfection in nature as a better signifier of evolution that the perfections.

The highlight starts at the 3:00 minute mark in the clip as Gould goes on to explain that a Pandas thumb is not really a thumb at all, but an evolutionary tinkering of a common bone in the wrist that evolved to suit the needs of a former predator that was never intended to eat bamboo all day.

Gould is an entertaining speaker and his depth of knowledge is impossible to ignore.  Science, and truly the world, lost a great communicator when he passed away.
