The Big Here
Kevin Kelly on an intriguing concept called The Big Here:
You live in the big here. Wherever you live, your tiny spot is deeply intertwined within a larger place, imbedded fractal-like into a whole system called a watershed, which is itself integrated with other watersheds into a tightly interdependent biome. At the ultimate level, your home is a cell in an organism called a planet. All these levels interconnect. What do you know about the dynamics of this larger system around you? Most of us are ignorant of this matrix. But it is the biggest interactive game there is. Hacking it is both fun and vital.
Accompanying his post is a 30-question (plus 5 bonus questions) quiz that determines how closely you’re connected to the place in which you live. Taking the quiz as he suggests (without Googling) and then researching the actual answers using the recommendations left by previous quiz takers is a useful, humbling, and instructive exercise.
Even though I live in Manhattan, a place where so much of the surroundings are unnatural and the inhabitants are effectively disconnected from nature, I decided to tackle the quiz and expected to do poorly. And so I did. Here are my results, with commentary. (There are some spoilers below, so if you don’t want to be swayed in your answers, take the quiz first, then come back.)
Answered correctly
1) Point north.
Easy with Manhattan’s grid, although you have to remember that the avenues don’t run directly N/S.
3) Trace the water you drink from rainfall to your tap.
Comes from upstate NY via various aqueducts and tunnels. I’ve seen parts of the old Croton Aqueduct in northern Manhattan.
5) How many feet above sea level are you?
I guessed 30 feet, Google Earth says it’s 36 feet.
9) Before your tribe lived here, what did the previous inhabitants eat and how did they sustain themselves?
A somewhat complicated question — by previous tribe, does it mean the English, the Dutch, the Indians, or the printing company that owned the building I currently live in? — but I basically know how all of those groups lived, more or less.
11) From what direction do storms generally come?
18) Which (if any) geological features in your watershed are, or were, especially respected by your community, or considered sacred, now or in the past?
The skyscrapers of midtown Manhattan wouldn’t be possible without all that bedrock underneath.
19) How many days is the growing season here (from frost to frost)?
180 days. (180 is in the ballpark, but it’s probably a little more given the proximity to the ocean.)
22) Where does the pollution in your air come from?
Cars.
31) What species once found here are known to have gone extinct?
Passenger pigeons?
Partial credit
2) What time is sunset today?
Within 15 minutes of the actual time.
7) How far do you have to travel before you reach a different watershed? Can you draw the boundaries of yours?
Across the river to New Jersey. (Locate your watershed.) I don’t know enough detail to draw it.
8) Is the soil under your feet, more clay, sand, rock or silt?
I guessed bedrock, but Manhattan’s bedrock comes to the surface near midtown and points north of there, not further south where I live.
13) How many people live in your watershed?
10 million. (Actual answer is 9.1 million.)
15) Point to where the sun sets on the equinox. How about sunrise on the summer solstice?
20) Name five birds that live here. Which are migratory and which stay put?
Pigeons, hawks, falcons, ducks, sparrows. Ducks migrate. (Turns out that falcons and hawks migrate too.)
21) What was the total rainfall here last year?
50 inches. Average is ~48 inches and last years precip was ~56 inches.
24) What primary geological processes or events shaped the land here?
Glaciers
32) What other cities or landscape features on the planet share your latitude?
Portland, OR; Rome, Tokyo.
Correctness unknown
10) Name five native edible plants in your neighborhood and the season(s) they are available.
Are there plants still native to Greenwich Village? Marijuana? We grow tomatoes in our apartment, does that count?
17) Right here, how deep do you have to drill before you reach water?
500 feet? (Now that I think about it, it’s probably a lot less.)
34) Name two places on different continents that have similar sunshine/rainfall/wind and temperature patterns to here.
East coast of Japan? East coasts of southern Africa or South America?
Absolutely wrong / no clue
4) When you flush, where do the solids go? What happens to the waste water?
6) What spring wildflower is consistently among the first to bloom here?
12) Where does your garbage go?
On the curb?
14) Who uses the paper/plastic you recycle from your neighborhood?
16) Where is the nearest earthquake fault? When did it last move?
23) If you live near the ocean, when is high tide today?
25) Name three wild species that were not found here 500 years ago. Name one exotic species that has appeared in the last 5 years.
I’m assuming Williamsburg hipster, Chelsea queer, and PR flack are not the answers they’re looking for here.
26) What minerals are found in the ground here that are (or were) economically valuable?
27) Where does your electric power come from and how is it generated?
28) After the rain runs off your roof, where does it go?
29) Where is the nearest wilderness? When was the last time a fire burned through it?
30) How many days till the moon is full?
Turns out it was just full.
33) What was the dominant land cover plant here 10,000 years ago?

I answered 9/35 correctly and 9/35 for partial credit. I wonder if I would have done any better if I still lived in rural Wisconsin.
Update: Matt Jones is interested in building a Big Here Tricorder:
What I immediately imagined was the extension of this quiz into the fabric of the near-future mobile and it’s sensors - location (GPS, CellID), orientation (accelerometers or other tilt sensors), light (camera), heat (Nokia 5140’s have thermometers…), signal strength, local interactions with other devices (Bluetooth, uPnP, NFC/RFID) and of course, a connection to the net.
The near-future mobile could become a ‘tricorder’ for the Big Here - a daemon that challenges or channels your actions in accordance and harmony to the systems immediately around you and the ripples they raise at larger scales.
It could be possible (but probably with some help from my friends) to rapidly-prototype a Big Here Tricorder using s60 python, a bluetooth GPS module, some of these scripts, some judicious scraping of open GIS data and perhaps a map-service API or two.
Physicist Lawrence Krauss sums up his thoughts
Physicist Lawrence Krauss sums up his thoughts from a small conference he organized on the topic of gravity. “There appears to be energy of empty space that isn’t zero! This flies in the face of all conventional wisdom in theoretical particle physics. It is the most profound shift in thinking, perhaps the most profound puzzle, in the latter half of the 20th century.”

List of the top 5 most popular blogs written by scientists. Here’s the top 50 and a list of popular science blogs written by non-scientists. What’s clear is that the blog reading public doesn’t care that much for science…more people probably read Engadget than all of the top 50 science blogs combined.

Unobserved people paid almost three times as much to the “honesty box” when watched by a photocopied face than in the absence of the face. See also What the Bagel Man Saw by Freakonomists Stephen J. Dubner and Steven Levitt. I wonder if the smiley face on milk cartons deters people from drinking straight from the carton?
Update: Spiegel Online has a story with a graph depicting the results of different sets of eyes…sexy eyes did the worst while serious eyes looking straight ahead performed the best. (thx, roland)

Natural deselection
Tom Coates recently checked out the Royal College of Art Summer Show in London and ran across this project by Tim Simpson:
…three plants compete to reach the light that feeds and nourishes them. The first one to succeed survives. The other two are automatically cut down in their prime.
First plant to grow close to the proximity sensors wins. A simple and elegant idea.

Excellent photos of giant flocks of European starlings, which can comprise more than a million birds. In 1866, a passenger pigeon flock was observed in southern Ontario that was a mile wide, 300 miles long, took 14 hours to pass, and was comprised of some 3.5 billion birds. That would have been a fantastic sight.

The hygiene hypothesis of allergies “argues that exposure to more natural environments such as farms early in life helps train the body to respond appropriately to harmless microbes and pollen”. Could also be called the “let your kids eat dirt hypothesis”. Somewhat related story: my dad had allergies when he was a kid but then got stung by a bunch of bees one day and boom, no more allergies.

Italian scientists have created glass made out of carbon dioxide. At high pressure, instead of forming a crystal (dry ice), the CO2 forms a clear, hard, vitreous material. More info. (Little known fact: I did research on glass in college, rubidium and cesium borosilicates mostly. Here’s a few citations on Google Scholar.)

I can’t tell if this is a joke or not, but someone seems to be quite skeptical about the “theory of gravity” on this Christian Forums site. “are you going to tell me that the gravity of the sun is strong enough to keep PLUTo in orbit but not an airplane or a little bird??????”
Powers of Ten
Some sweet soul has put Powers of Ten online. If you’ve never seen it, I can’t recommend it enough:
Powers of Ten is a short film by Charles and Ray Eames, whose work you may have previously sat in. The film starts on a picnic blanket in Chicago and zooms out 10x every 10 seconds until the entire universe (more or less) is visible. And then they zoom all the way back down into the nucleus of an atom. A timeless classic. (via youngna)
Update: How in the hell did I miss this Powers of Ten Simpsons couch gag? (thx, ray and jeff)
Bill and Ted’s Excellent Adventure
I know I’m going to get mail about my five-star rating for this movie, but it cannot be helped. One summer when I was a kid, a friend and I watched Bill and Ted’s Excellent Adventure — no joke — every single day for a span of 2 months. I still know every line by heart, the timing, inflection, everything. If there were a Broadway production of this movie, I could slide effortlessly into the role of either Bill S. Preston, Esq. or Ted Theodore Logan, no rehearsal needed.
In my high school physics class my senior year, we had to do a report on something we hadn’t learned about in class — which, I discovered when I got to college, was a lot — and I did mine on time travel. I went to our small school library and read articles in Discover and Scientific American magazines about Stephen Hawking, Kip Thorne, quantum mechanics, causality, and wormholes. To illustrate the bit about wormholes, I brought in my well-worn VHS tape of Bill and Ted’s (a dub of a long-ago video rental) and showed a short clip of the phone booth travelling through space and time via wormhole. I got a B+ on my presentation. The teacher told me it was excellent but marked me down because it was “over the heads” of everyone in the class…which I thought was completely unfair. How on earth is Bill and Ted’s Excellent Adventure over anyone’s head?

Al Gore, movie star
An Inconvenient Truth, a movie about Al Gore’s global warming crusade, opens today in NYC and LA. John Heilemann has a lengthy piece on Gore for New York magazine, the NY Times has a piece about Gore and the movie, the climate science blog RealClimate has a positive review of the film, and here again is my review. Larry Lessig, who knows a thing or two about bringing tha PowerPoint noize, loves the movie, calling the slideshow “the most extraordinary lecture I have ever seen anyone give about anything”.
An Inconvenient Truth will open in the rest of the US in mid-June; check this theater listing for details. For more news, check out the movie’s blog.
