Dusk on the edge of the bay

The time between anniversaries of the uranium bomb dropped on Hiroshima, plutonium on Nagasaki, have the same off-center pull on me of the awful hours on Good Friday. Attaching this disequilibrium to specific times is, of course, a human conceit, as is dreading the inevitable.

Still....
***

 The mid-moon evening tide lets us wander out onto the tidal flats at dusk--there's still a hint of color on the western edge of the bay, but the sun sank a half hour ago.


I wander around collecting horseshoe crab molts, the exoskeletons split along the front edge, where the sea creature wriggled its way out of its shell, self actualization in action. The husks of these ancient creatures hold no flesh.

As I scuffled my feet in water only inches deep, a globular critter wiggled its way from the edge of the sea back to the depths, and I pondered whether it was a sally growler, a croaker, a northern star gazer, or something else.

As if a name matters to it, to me.

To anything.




The shells in the photo were collected two dusks ago.
The critters that once claimed them are likely wandering around in the brown cool depths of the Delaware at this moment, unaware of anniversaries, but not unaware.

Awareness is not what makes us human.

Horseshoe crab graveyard

 Horseshoe crabs and I have a long history.
 Theirs longer than ours.





These were tossed up on a huge hill of dredge waste, peering through the gray mud.




I have witnessed much, most unspoken, in my years, as I am sure you have, too.

I do not understand, or trust, my silence.


Their blood runs blue, copper grasps the same oxygen molecules that let us strip electrons from our food.
 Our blood runs red, the deep rust of iron, 

Most of us can see, most of us can talk.

Our stories remain as opaque as the mud deep below the waters of the Delaware Bay, where now in the darkness, a solitary horseshoe crab consumes a careless clam, neither ever seen by humans.

 

They have not changed much in hundreds of millions of years, their life perfect for their world.



And now they rest on the spoils made by us, we who are impossibly foreign in our own skins, looking for something beyond this life.








When you walk the fissured hillock on a chilly April morning, the exoskeletons whisper what they know.



This is all, and all is enough.

A response to a technophile

This post is a mess, an amalgam of several yet-born posts swirling about.


This is a tool, made by Takeshi Yamada,  an artist who saw visions while surveying horseshoe crabs on the shores of our bay.

It is a pen crafted from the tail of a horseshoe crab. Mr. Yamada uses it almost every day, to create stunning images.

Compared to some tools, his pen may be thought inefficient. It certainly lacks the precision of a YAG laser engraver , or even a Koh-I-Noor 5611 drafting pencil, but that's not the point. That's not the point at all.

Mr. Yamada is human, with the same frailties as any of us, with the same natural curiosity. He did not learn to use his telson in an American school. There is no place for it there.

Unique does not guarantee better. Unique things are often unique because they are not worth reproducing. Technology thrives on precise, efficient, reproducible results. There is little room for Mr. Yamada in the industrial world.

Mr. Yamada's work, however, gives me pleasure. His work pleases others as well. Someone shared it with me, now I share it with you.

Gerald Aungst, "a supervisor of gifted children," writes for Connected Principals, a shared blog written by school administrators, a blog well worth visiting. His recent post "Why 'I Don’t Do Technology' Isn’t Acceptable" raises some good points, and I have no qualms with the thesis of its title. His arguments within the article, however, reveal some interesting thoughts shared by many technophiles, and I'd like to offer some views from the other side of the aisle, an aisle I straddle with my Google + account in my right hand, my Dixon Ticonderoga No. 2 pencil in my left.

Go read the post. I'll go check my sundial and pick weeds from my garden while you read.

"Some people argue that technology is simply a tool to be applied where and how it’s appropriate. Others say no technology is neutral and we have to be deliberate in our choices to use it."

The two are not mutually exclusive--"appropriate" covers a lot of ground. We also should consider what is lost when a newer technology is used. Reel mower vs. gas-powered rotary. Pencil vs. pixels. Chalkboard vs. IWB.

I'm a retired doc--before I stopped succoring the afflicted I saw the mess high tech mania produced in medicine. Mr. Aungst's example of the CT machine is an interesting example, because of the quandaries it has created, and because of the change in skills that have resulted.

Classic appendicitis (and many subtle variants) can be diagnosed by history and physical exam alone if the practitioner has learned how to do this. CT scans are quite useful in certain situations, but are often superfluous, and can, at times, mislead. They certainly tangle up a few DNA molecules (which are usually repaired), and they are very expensive.

The obvious downsides to CT imaging is that it takes time (and time is an issue with appendicitis), and it requires tossing some radiation through a living critter. Less obvious is the erosion of skills in tech-dependent docs. By the time I left medicine, CT scans were evolving from an overused, nonessential tool to standard of care, partly because the less experienced docs felt no need to refine the clinical skills needed to accurately diagnose appendicitis--because they had CT machines....

High tech has supplanted the low tech history and physical examination--if you delve into the luverly world of Bayesian statistics, you start to grasp why this matters. I loved CT machines--but I used them judiciously. No, you do not need one just because you hit your head. But thanks for asking....

***
"Everything that we can do using digital technology can certainly be done in some other way. As I understand it, technology gives us three capabilities: to do things

  • More efficiently
  • More precisely
  • More thoroughly"

Well, no, and no. Some things done with digital technology cannot be done any other way. I'll save that for another post. The second part, though, intrigues me because it gets a deeper question. Why the hurry?

Given the phenomenal information now (efficiently, precisely, thoroughly) available to all of us, does pedagogy require the same technical sleekness? Do our classrooms need to follow the industrial model of production? Is this even possible? The Slow School movement makes a nice counter-story to the frenzy spawned in Silicon Valley.

If you believe that our current cultural practices have had disastrous effects on our seas, our air, our children, maybe stepping back a bit to reflect on what matters, itself not a particularly efficient activity, then efficiency loses its luster. If we took the time to reflect on our practices, to appreciate the depth of consequences we make with our choices, would the shimmering cognitive dissonance awaken us enough to change? Or would it drive us back into the dull din of relentless data, back to our coffee and wine and the digital distractions of our [dis]connected lives.

 "Why you'll love a Mac. A Mac is as good as it looks."

"Technology advances give all of us—doctors, forensic scientists, teachers, and students—the ability to make better decisions...."
This is where our paths divide. "Better decisions" is a huge category--and "better" is as slippery as butter. The large cultural decisions we have made (or have had pressed onto us) the past few generations have had consequences, huge consequences.

Our current air of Western superiority is fueled by cheap calories pumped up from the ground, from finite sources. Our tremendous gains in growing food stem from our ability to fixate nitrogen through the Haber-Bosch process, also dependent on finite sources. We have the time to ruminate, though few of us do.

The same technology that allows us to chat with our "neighbors" half a world away allowed a British "Reaper" un-manned drone to kill civilians in Pakistan using digital communication from an airbase in Nevada. Yes, it was an accident. It wasn't the first time--two children were injured via remote control in 2009. No, it won't be the last.

High tech allows us to make quicker decisions--but if technology makes us capable of better decisions, I'd like to see the evidence.

***

At the end of each school year, I take over a hundred kids to see horseshoe crabs mating along the Sandy Hook Bay. While a few critters may end up frustrated by coitus interruptus sophomoribus, a few humans leave the tide's edge feeling a little bit more connected to the world, and, perhaps, a little bit more in love with the world.

Some of them may end up in Afghanistan, the ones least likely to find it on a map. The Japanese call the horseshoe crab kabuto-gani--"the warrior's helmet"--because of its similarity to the headgear worn by the samurai, a culture that forbid killing by stealth.



We don't dwell on these things, those of us protected by money and class here in the States. They make us uncomfortable.

Teaching science requires some cognitive dissonance, which is convenient, because allowing a child to become more aware of her universe will lead to huge doses of cognitive dissonance. If I aim for efficiency, the children in my class can hide from their dissonance.

Mr. Aungst's article and the subsequent discussion are a wonderful start to why technology matters in the classroom, and who can disagree with his assertion that "educators have accepted responsibility for the growth of the students in their care."

I think we need to discuss what "growth" needs--deeply, slowly, thoroughly, if not efficiently. We'll need some technology--comfortable chairs, maybe a glass or two of something brewed, perhaps a guitar, and artificial light if our chat extends past sunset. We mostly need ourselves and our love for what we do.

Care to join the discussion?

Another horseshoe crab story

I fished in thigh deep water today, surrounded by gazillions of horseshoe crab eggs, most of which will be eaten in the next day or two. A small fish, obviously versed in the Curly and the Oyster Stew episode, kept grabbing my lure just as I was pulling it out of the water, then gleefully letting go just as it broke the water's surface.




A rather exuberant male horseshoe crab got flipped in the waves as he tried to mount the love of his life. A small child, no higher than my waist, approached it, and an older, officious looking child warned him to stop, that the tail would sting.

I can hardly bare officiousness at any age, but it's particularly sad to see in a tween, so I broke away from the playful fish, picked up the horseshoe crab, and showed the child that the tail is perfectly safe. (Well, I guess I wouldn't run with a live horseshoe crab--I could trip and accidentally poke my eye out, I suppose.)

Myths matters. Decades ago I slaughtered dozens of horseshoe crabs on a very hot August afternoon, their blue blood covering us in our frenzy. The life guards had told us, a gang of 9 and 10-year-olds, that they were dangerous, and fearless as we were, we attacked the seemingly loathesome critters.

It does no good for me to tell the officious one that he was wrong. He saw what he saw today, and fear's a funny thing.

The younger child, however, gleefully touched the squirming horseshoe crab. He touched the tail, the shell, the tiny claws, the lucky bones, pretty much everything there is to touch on a horseshoe crab. Before the day is done, I bet he shows a few others his size that the critters are harmless.


The officious one stood off to the side. Not my intention to embarrass him. Maybe he will hold a horseshoe crab before his week here is up, maybe he won't, but he will be a little less certain in his fear next time one tumbles up out of the surf.

How many of my fears remain from my ignorance, even now, old as I am? How many do I unwittingly share with others?

Pssst...don't hold them by their tails.

Quick report

We took about 150 kids to Sandy Hook today, just as the high tide of the new moon of June was receding.



Horseshoe crabs, oblivious to our presence, did what horseshoe crabs have done for millennia.

A few dozen horseshoe crabs danced at the water's edge. Thousands upon thousands of impossibly blue-grey horseshoe crab eggs floated in the water.

Four huge, filleted drum littered the beach.


When the young of the H. sapiens species mix with the old of the L. polyphemus, good things can happen.

And they did.










Thank you PSEG, Bloomfield BEF, BHS administration, and all the chaperones for making this day a tremendous success.
Learning, truly learning, about horseshoe crabs (or any other form of life alien to our culture) will not help on any NCLB exam. But it will change a life, in a good way.
I teach children. Today was a good day. Photos taken by the kids.

Bleeding on Memorial Day

My hands were awash with  patriotic colors this morning. Blue blood of a lovely lady horseshoe crab, hooked by a lad whose enthusiasm, alas, could not compensate for his ignorance. Red blood of a dogfish, also hooked by the exuberant one. His first fish. Ever.



I landed and unhooked the fish. The child posed with it, two feet of shimmering muscle wrapped in sandpaper.
Can you eat it? 
Sure, if you bleed it first--

The father never acknowledged me; he refused to let the child take home and eat the fish.

"Nobody eats those things," he muttered. His eyes flashed fear when the dogfish had first broken through the surface.

The child looked at me. I had already shown him horseshoe crabs were harmless, letting the child brush his hands along the wriggly harmless claws. I had already shown him how to  handle a "shark," letting him run his fingers along the sandpaper skin. He trusted me.
You can eat it, I said once again, quietly--no reason to embarrass the child or his father. But it'll be fine if you let it go gently.
 He believed me.
***

Both the dogfish and the horseshoe crab had real reasons for fear. The milky blue blood oozing from the injured horseshoe crab may marks its doom. The bright red drops of blood on the handle of my net, now a dull burgundy, will cost the dogfish.

Neither knows of Memorial Day, when we splash red, white, and blue on our homes celebrating the brave young folks fighting over in lands we cannot be bothered to learn how to pronounce, battling ideologies in a futile attempt to defeat fear.

We fear, and we slaughter, those things we do not understand. The father has chosen ignorance, his child is still open to learning.

The child learned a little bit about fishing today, a little bit about the critters of our bay. He learned a much bigger lesson about ignorance, and he has a picture of himself holding a magnificent animal he feared moments before the photo was taken.

Our ignorance kills us. The local jetties are missing a few young men and women who are thousands of miles away. We barbecue and play in their names.

How many of us really know their stories? How many of us  want to know?





Yes, I am aware of the inconsistencies--fishing is complicated, and it's not.

Just to see stuff...

I wasted a day today prepping my lambs for the New Jersey Biology Competency Test. I will waste another day on Monday.

I have no idea what it means to be competent in biology, and judging by the practice questions, I am not alone. If a child passes the biology competency test, is she a biologist?

I chased a herd of daphnia today in one of my tanks--we have about 10 in the room. A child from another class came to visit today, just to see stuff.

We have a generation of children who do not see stuff. We have a generation of adults who do not see stuff. We can't even blame the gods-we've gone done outsourced hubris.
***




In a couple of weeks I will lead almost 200 kids on a trip to Sandy Hook. We will hold fiddler crabs and grass shrimp and pipefish and horseshoe crabs. We will get too much sun, and a few of us will lose some red blood cells. Children will watch the tide fall--we cannot stay long enough to watch it rise again.

We will hunt for hermit crabs and whelks and killies and mussels.

The children will see that the world is for them, of them, and that it is, ultimately, incomprehensible. Science is, to paraphrase Richard Feynman, understanding how nature behaves. The "why" I leave to the priests, the astrologers, the charlatans--grasping the how is more than enough for a thousand lifetimes.

And what, really, will help a larval human "get" science? Prepping for a test given to meet the demands of a few aged men sitting in fancy buildings just over a couple hundred miles away? Or walking along Sandy Hook Bay in early June?






A shame I even need to pose the question. A bloody shame....

Formalizing informal science

I got an email from Education Week this morning that prompted this.

Conclusion 1: Across the life span, from infancy to late adulthood, individuals learn about the natural world and develop important skills for science learning.



I'm taking my lambs to Sandy Hook in a month to watch horseshoe crabs mate, to hold a few fiddler crabs, to seine the bay and see what they find, and to pick up a little trash while they're there.


For at least one day, I do not fret over my biggest classroom fear--killing curiosity. (I fret over a bazillion other things--bleeding, sunburned, and drowning dreams will haunt me for the next month.)

A 2009 National Resource Council report suggests that informal science--going to museums, watching Mythbusters, or looking under rocks in the backyard--matters if the goal is to spark lifetime interest in science.

But we have a problem--no immediate way to measure the effects of informal science, at least in a way that compels the data-driven drones who have co-opted our schools:
Without a common framework specifying outcomes and approaches, it is difficult to show gains in learning that occur across localities or across time frames, and attempts to portray the contributions of infrastructure for science learning that exists across varied institutions and activities will continue to be hindered


Our data-driven ed culture does not  accept what it cannot effectively ostensibly measure. So we continue to do what we know doesn't work! How do we know? We have a decade's worth of NCLB data....

*** 
Conclusion 8: Designers and educators can make science more accessible to learners when they portray science as a social, lived experience, when they portray science in contexts that are relevant to learners, and when they are mindful of diverse learners’ existing relationships with science and institutions of science learning.

Conclusion 14: Learning experiences across informal environments may positively influence children’s science learning in school, their attitudes toward science, and the likelihood that they will consider science-related occupations or engage in lifelong science learning through hobbies and other everyday pursuits.
Here's an idea--why not try this inside the school building? We have the students for a good chunk of their awake hours.


Every science teacher, and every school administrator, should read the report. You can read it free online.






The conclusions were lifted directly from the 2009 report Learning Science in Informal Environments: People, Places, and Pursuits,

Horseshoe crabs redux

I saw that someone Googled "can you pick up a horseshoe crab" today to find my blog.
I found a half dozen tiny horseshoe crabmolts on the beach today, the smallest the size of my thumbnail.
I rescued an ancient old female, caught high on the beach, twice today. Flies had settled on her the first time around, she shoved off the second. This may well be her last year, but not her last day.

So I brought this back....


Spiders, really.
And like spiders, feared.

Kids, really.
And like kids, fearless.

I was 8, old enough to know better. The lifeguard, bronzed and confident, draped in red, asked us to slaughter the horseshoe crabs.

"Hold them by the tail so they can't sting you, then smash them on the wall."

The wall--a creosote bulkhead jutting into the beach, already slimy with the blue blood and cracked shells of these fearsome creatures.

It was mating season. Not yet old enough to understand a desire that drove these beasts onto my beach, Ideal Beach, I smashed one creature on top of the others, picking the same one up over and over until the shells splintered and the sky blue blood soaked the shells underneath.

Sea gulls pecked into the soft flesh of our dying prey as the legs were still scratching at the sky.

When we were done, tired, stinking, and proud of our aching muscles, we jumped back into the water, washed ourselves, then went home.



Hemocyanin: blue blood. We wore it that day like war paint--stinking of death, sweating under the early July sun.

20 mg of high purity hemocyanin will fetch $175.00

20 milligrams.
Less than the weight of a fat housefly. Less than the weight of our soul. Our blood runs red from the iron in hemoglobin; a horseshoe crab's blood runs blue from copper.

Hemoglobin is cheaper.


Every spring the she crabs come to the beach, several smaller males trailing behind. The bayshore teems with horseshoe crab eggs, tiny bean curds at the lip of the beach. Millions upon millions, so many that none mean anything at all to me. Birds crowd along the beach, feasting. I used to think the birds were what mattered.

A female crab can lay 80,000 eggs in a season. She creeps up onto the beach, riding the spring tide on the full moon. She crabs reach sexual maturity in 9 to 12 years, not much younger than when humans do. May is crazy with life everywhere. Within 2 to 4 weeks, they are ready to hatch. I never really looked at the eggs closely, until last year.

It took me a long moment to believe what I was seeing. Horseshoe crab eggs do not remain opaque. Soon before they egg splits, the tiny pale crab spins wildly. Half the egg is clear, the other half white from the curled embryo. If you look carefully, you can tell that this tiny critter is a curled up horseshoe crab. As it spins, it looks like a tiny blinking eye.

If you watch one long enough, you will catch its birth. It will already have survived longer than most of its siblings. And it will not likely survive the next high tide.

Still, catching the exuberance of a newly hatched critter the size of an ice cream sprinkle on a warm, June afternoon changed me. Strangers saw a wild-haired middle-aged man squatting by the water's edge, staring intently at nothing, gesticulating a bit too much for others to come share his excitement.

I would not have let my kids close to me, either, had our roles been switched. Fortunately for my kids, I am not a stranger.


The smell of a dead or dying crustaceans can overwhelm a kitchen. On an open beach, however, mixed in with the salty life-teeming spray, a balance is reached. At high tide, the smell is almost too clean; at low tide, whiffs of the decaying mud is sharp, but not repulsive. The tide washes over us twice a day, the rhythm of mortality.

I occasionally find horseshoe crabs stranded on the beach. I will gently pick them up, and return them to the water. I may have returned thousands by now. I cannot make up for the hundred I slaughtered. That is not why I do it.

Every summer I show children how to pick up a horseshoe crab. Cradle the carapace with your hand. Do not carry them by their tails. I touch the point of the tail, show a child there is no stinger. They are gentle creatures. Omnivorous, true--clams, worms, and algae, so perhaps not so gentle, but certainly not harmful to humans.

Young loggerhead turtles snack on horseshoe crabs. Humans use their blood in medical research. Otherwise, they have few "enemies." Not sure being higher up in the food chain makes one an enemy. Someday I will feed the worms, unless some stranger stuffs my veins with formaldehyde and buries me too deep to be useful.

Horseshoe crabs live an average of 19 years, or so the scientists will tell you. I doubt the average longevity matters to a horseshoe crab--the mad, exuberant spinning of horseshoe crab embryos one June afternoon reminded me what matters.

Ask me someday....ask me in June. I will show you. Words will not do. I bet you smile like an idiot, too....

The end of winter

Our crocuses bloomed today. A tiny horseshoe crab, smaller than my thumbnail, crawled out of the Delaware Bay. The day lilies are rising again, like Phoenixes from the snow's ashes.



All of this is more real than the nonsense that passes for discourse in the education world. I can still close my classroom door (though I rarely do) and tackle whatever problems we care to tackle that day.
Why is my plant wilting? Hey, sow bug babies! I think my slug drowned.
How come the starfish hasn't moved in three days? Are those mosquitoes?
Look! Peas!
We got kids from Somalia, from Sierra Leone, from Poland, from China, from Ghana. Not third generation, not second. We're talking off the airplane (Newark Liberty International Airport) and into the brink. I taught a child who spoke only Bengali.

And we thrive.

We thrive despite the mandates, the tests, the current climate that forgets the roots of the word public, "pertaining to the people." Our town supported the last budget, despite the struggles of family after family after family.


Families that come from desperate situations know education matters. Families that come from desperate situations value teachers who care about their children. They put their trust in our hands, in our classrooms.

So while the elite press on about this magnet school, that philosophy, the myriad ways to use (and abuse) technology, scouring the US News and World Report for college rankings (and the NJ Monthly for state rankings), most of the rest of us go about our business, getting children ready for loving, happy, and (yes) productive lives.


But never just productive.

I work for Bloomfield, and its families, and for its children. I do not work for Arne Duncan, I do not work for Governor Christie. I give my all every day, because I want my lambs to be happy, in the Jeffersonian sense, and I want them prepared to pursue whatever dreams they hope to pursue.


I wiled away a good chunk of the afternoon on a jetty poking into the bay. I stared at barnacles for a bit, mourned all the oysters scraped off the rocks by this year's ice. The water was exceptionally clear, revealing thousands of comb jellies, floating in with the tides, then floating out again.

My happiest moments are spent on the edges of the sea. 


I stumbled upon the horseshoe crab, not much different than its ancestors that wandered these same shores when dinosaurs still roared. It may be still alive, it may be in the belly of a gull now. Tomorrow I will share its story with my students, because for them, these stories still matter.

And then I will test them on meiosis and synapses and centromeres and chromatids, to get them ready for the state exam in May. Those who finish early will be allowed to study their terrariums, their aquariums, to see how their critters did over the weekend.




 And the day will not be completely wasted, the last Sunday of February, as the light returns, and all things, all things, again become possible.






All photos taken today.
 First one crocuses, then the tiny (and live) horseshoe crab, then the points of a dead horseshoe crab, 
then barnacles hanging out waiting for the next tide, 
and finally, light as seen through the compound eyes of a horseshoe crab.

February horseshoe crab


Leslie and I found the tiny shell of a young horseshoe crab this afternoon while walking on the edge of the Delaware Bay.

The shell is backlit by our sun, the source of just about all our energy, whatever "energy" means.

I can construct all kinds of things on computers, create all kinds of worlds, live all kinds of lives, and none of it, none, can compare to the miracles we find with each step we take on the beach outside.





A loon surface no more than 10 feet away from us today. The water was clear. The sanderlings are gone.

A February horseshoe crab



I love this picture.

My wife has tiny feet--that is the tip of her tiny shoe. The tracks were made by a tiny horseshoe crab last February. Chances are pretty good no one else has seen this particular horseshoe crab, and chances are pretty good it is no longer alive.

But it might be. It might be just a mile off our beach, poking along mud 30 feet below the bay's surface, bigger now, munching on whelk. No way to know.

If it lives a few more years, it may return to our beach to mate. A curious child may squat next to it, an ignorant child may run away screaming. A fisherman may snag it with a morsel of squid, his hands washed in creamy blue blood as he struggles to dislodge the hook. A wave may flip it over, and before it rights itself, a gull may peck at its gills as it flings its telson (not a "stinger"),  into the wet sand, trying to right itself.

But last February, it sauntered along our beach, no more than an inch long, feeling its way along a world I cannot imagine.
***

Horseshoe crabs see light we cannot. They have 10 eyes, the two obvious ones sitting on top of the shell--they are used to find mates in the gloom of the bay.

They can "see" light with their telsons, their "tails." They have tiny eye-spots on the front of their shells, designed to see ultraviolet light from the sun, from the moon. They know when the moon is new, when the moon is full. Such news is obvious on the edge of the shore, of course, but not so obvious deeper in the bay. The horseshoe crabs time their orgies to the moon.

They also have eyes underneath, next to the mouth--to see what?

We can pretend to know what it means to have 10 eyes, to sense UV light, to rise from the depths to mate under moonlight, but it's all pretending. We cannot know the universe of the horseshoe crab. But we can know that it exists.
***

I have a classroom set of netbooks, from very generous donations by the Roche Foundation, by the Bloomfield Education Foundation, and by our local Home and School Association.

I love what we can do with them: students can collaborate on projects, we can grab information on the fly, and there is a huge gee whiz factor built into these tiny machines that can liven up a classroom. They are not, however, a window into the world.

The only world visible on a monitor is the human world. Even high resolution photographs of exotic life are just that--human inventions, pixels flashed through electronic streams. They are not real.

A human framed the moment. A human cropped the photograph. A human machine translates the signal into the image on the screen. It is flat. It is manipulable. It is not real.

Oh, but think of the children who do not have access to these wonderful creatures!

I'd rather think of our reluctance to let the children get access to what lives among us.


My daughter, very young at the time, once found a pigeon's nest under the creek bridge that led to our closest park. She watched it for weeks, first eggs, then tiny critters, then fledglings, then gone.

She wrote no reports, took no photos. She just watched.

We keep roly polies ("pill bugs") in our room--harmless crustaceans that bumble around in a few of our terrariums, going about the business of the living, sometimes doing a whole lot of nothing.

My kids can learn all kinds of facts about them from the internet, but the only thing they really need to know for now is what to feed them, how to keep them healthy. Kids ask me, and I explain that I really don't know, because, well, I really don't.

We see that they only shed half of their shells at a time. We see that they tend to hang in groups. We see their antennae busily working the world immediately in front of them. Occasionally some die, occasionally new ones appear.

No pixels, no chips, no pressure. Just our classroom companions, who will be brought back to the outside world when the sun returns.
***

And what do the children take home with them? I do not know, I'll have to ask them years from now.

I do know that if the kids do not see life beyond the human walls now, it is unlikely to happen later.
I also know that most children (and most adults) confound the world we created with the world that exists. Our economy depends on the fantasy.

So I teach biology. Life. And life cannot be found in a chip.

National Lab Rat Day

We all have a vested interest in advancing our country’s proficiency in the disciplines of science, technology, engineering and math as a means to driving innovation and jobs — which are key to fueling our economic growth and global competitiveness.
Steve Ballmer
CEO, Microsoft



Yesterday was National Lab Day--major corporations, foundations, politicians, and business folks got together to fuel a national PR project to push technology under the guise of science. Again.

Technology serves the self, science is another beast altogether.

We teach mostly technology in high school--it's what the corporations want, it's what the Feds want, it's what parents want. Get edumacated, get a degree, get a career, get fed, get laid, maybe have kids, and eventually get dead. I'm not saying that's a bad plan, at least not publicly, but it does require limited vision. Thankfully, we live in a culture that's designed to provide the blinders.

Science, unlike technology, serves no one. It is selfless. Peek beyond the hoopla of equations and models and jargon and the floor falls out of the universe.

Or rather, the universe, it seems, has no floor.

If I could teach this to 15 year old brains, bad things would happen. Fortunately, their brains are not mature enough to grasp this, and I'm not half the teacher needed to teach this. Even with tenure, I'm not sure my career could survive a class of children grasping how tenuous reality is.
***

Pick up an object you know, one that gives you comfort, maybe an old shell. It feels solid, has some heft, it's real.

Yet it's mostly empty space.
Yet is is tugged by every other object that exists in the universe.
Yet its elements were fused in the vast gravitational depths of some unknown star.
And maybe most stunning, the oyster was once alive, a sentient creature, and no longer is.

I do not teach religion in class, I teach science. You get to the edges of it, though, and words fall apart. When words fall apart, walls, which are mostly space anyway, fall apart as well.

If a child is locked in a human universe, culturally bound to the myths that will help her become the successful careerist she's been taught to want, grasping even basic physics may ruin her as surely as mainlining heroin.

Thankfully, a child can fly through school "knowing" all kinds of equations without truly understanding their implications. We keep science safe.

Steve Ballmer wants your kid's brain wrapped in gauze. I want your kid's brain so open to possibilities that it oozes all over the universe. I admit his version is more likely to lead to financial success.

But I bet my version is happier.

If anyone asks, say "Limulus polyphemus"



We're taking a bunch of kids to Sandy Hook.

We will be looking for horseshoe crabs, pipefish, eels, and anything else we can legally catch and release. (Clams, alas, are out--even with a license, raking for clams is illegal in condemned areas.)

Many of my kids have never seen a horseshoe crab. Many of those that have, fear them.

Every day from now until the trip I will remind the children that if anyone asks, we are going to study Limulus polyphemus. I work under great conditions, under a wonderful supervisor, but why start trouble?

OK, what do you say if someone asks why we're going to Sandy Hook?
Limulus polyphemus!
What do you say if someone asks you what we're studying?
Limulus polyphemus!
What do you say if someone asks you how nuclear fission works?
Limulus polyphemus!
Spew out a scientific word and folks go running.

Part of teaching is getting observed. I don't mind it so much, and prefer frequent, unannounced visits to formally planned lessons since it gives the administration a better idea of what happens in my class, which (ideally) gives me better feedback. I love gold stars as much as anyone, maybe more (I had a lot of concussions growing up), but I learn most from the occasional disasters. A second pair of eyes helps me dissect them better.


Folks without a scientific background, however, often preface their remarks by saying science is too hard, so they didn't really get the lesson. I don't hear anything else said--I am completely deflated. If I cannot teach an administrator a concept I'm expected to teach to children who still believed in the tooth fairy a few moons ago, what's the point?

(And yes, I get another gold star for my collection....)
***

So here's the point--we live in a wonderfully complex , ultimately inexplicable,universe. (OK, that was too much of a mouthful--go stare at an ant colony for a few minutes and get back to me). This fantastic universe appears to be governed by teasingly simple laws.

If I ever hope to get a child interested in grasping these laws, a child who just rubbed a amgazine advertisement for Stetson cologne on his chest while leering at another child who (it seems) forgot to put something on over her stockings, I need to get them outside themselves by getting them outside.

If the Park Ranger asks if we have a permit, I'll just mutter Limulus polyphemus....

Apropos nothing two....


I went fishing yesterday, tossing a bucktail into a channel behind West Wildwood. The sky was steely, a mist was falling, and the bugs enjoyed slurping hemoglobin from my scalp.

I didn't catch anything, which was fine with me--I have scallops from Walt the scalloper in the freezer waiting for next Saturday, and we have a chunk of last summer's fluke waiting for us as well.

While working the beach I stumbled across a couple of the holes we left clamming the day before--I fill my holes, but the bay was double-checking my work. A few feet from one of the holes I saw a grand-daddy of a quahog--a huge chowder clam just sitting on the flat exposed by the low tide.

A quahog that big may well rival me in years on this Earth. It didn't get that large by acting stupid, and here's hardly enough nervous tissue for clams to get senile. Still, there it was.

I went to pick it up. It resisted.
I went to pick it up again. It resisted again, as if glued to the beach.

I tugged yet a third time, and the sands shifted--the clam was stuck to the base of an old horseshoe crab, now buried in the sand. Her kicking legs pushed the sand next to the clam.

A large horseshoe crab may well be 20 to 30 years old.

Here they were, an old horseshoe crab tethered to an even older quahog, waiting for the tide to rise. The quahog, guided by millions of years of instinct, clams up tight at low tide. With the edge of the horseshoe crab wedged along it edge, though, it faced dessication.

I tried to remove the clam again, but dared not pull any harder than I did. I left the two critters there to square their issue with the next full tide.

Some things cannot be anticipated, and some things cannot be fixed.

Ambergris


Leslie and I took a walk along the edge of our world, as we do most Saturdays. The tide was out.

At the edge of our universe, we witness miracles. Today we saw a 1" horseshoe crab the color of sand, not quite a yearling, making the universal horseshoe crab tracking pattern. I rescued an older one, at least a decade old, flipped upside down, a gull nearby eying its gills.

The beach is littered with blue crabs recently dead, their murderers betrayed by the tracks of webbed feet.


The February wind whipped through our coats.
It's still winter here.



And then I stumbled on this:




Its earthy marine aroma seduces me, and repulses Leslie.

I think I've found a good chunk of ambergris, worth something back in the days before chemists played gods. A decade or two ago, a sperm whale wrestled with a giant squid, perhaps a mile deep, and won. The squid's beak took one last stab at the whale's gut, which formed a protective coating of, well, whale excrement around the squid's last charge.

The beak was eventually expelled, either as poop or vomit, neither method particularly charming, and after years in the sea was tossed up on our beach.

If anyone wants to buy it, let me know. In the meantime, I'll keep sniffing it, drawing up images of death and delight in the deepest recesses of my hind brain.



It was 2 years ago February that I tossed a whale's tooth back in the drink.
I wish I held onto that. Far more interesting than a piece of poop.

New Year's Day


And so we're told this is the golden age
And gold is the reason for the wars we wage
Though I want to be with you
Be with you night and day
Nothing changes
On New Year's Day
U2, New Year's Day

Leslie and I went for a long beach walk on New Year's, as we have for years, and as we will, God willing. I liked the first walk so much I went for another as the sun slid over the edge of the bay.

We do this instead of resolutions.

I cannot adequately describe a winter beach, but I will try. The thoughts are scattered, as my thoughts usually are, and I am laying them down for me, to remind me what matters in the next few days, few weeks, few months, as I go back to the classroom.

At low tide, the Delaware Bay recedes from our flat beaches as though swallowed by the first of The Five Chinese Brothers.

The light is a riotous gray--steel gray sky against a changing gray sea. The splashes of white from the waves seem out of place. If you look at the sky, patterns emerge, a blue-gray swirl blending with a patch of green-gray, ever-changing.

The wind whistles through your hoodie, occasionally overwhelming the mesmerizing call of the waves. The waves never stop, they never stop. Sometimes I do not hear them, then remember they never stop, and I hear them again. A crow caws. The gulls were strangely silent.

You smell the salt air tinged with odd sweetness of bay mud. In the summer, the death smell of the bay mud is more obvious, but less noticeable. In January, the tinge of death is dulled by the cold, but on this wintry beach there is little visible life to deflect its message.

I dug into the mudflat, to find a clam. The water stings. Later, on the way home in a cozily warm car, the aroma of the little mud left on my hand overwhelms my thoughts.

We saw a few vultures hovering over the beach a couple hundred yards up--beneath them, a large sea gull dragged its tattered left wing, foraging the ebb tide for the last time. There was enough life left in the gull to scatter the vultures. They will return with the tide.

At low tide, the tidal flat reaches out hundreds of yards--in the distance I saw a lone blue heron standing at the edge of a tide pool. There is enough life to sustain her. I look harder.

Tiny whelks are buried in the mud--the air is near freezing, the water a cozy 40 degrees F. There's more life present than I had realized.

About 30 yards away I see a huge horseshoe crab shell. I worked my way through the shallow pools to the shell, perhaps to use for class.

The shell is half buried in the mud, with characteristic tracks leading to where she lay--the horseshoe crab was very much alive.

I was tempted to move her back into the water--if the temperatures dropped below freezing before the new tide flooded the flats, she would freeze.

A large horseshoe crab is almost always female; one this large certainly was. She was likely near 20 years old, old enough to know what she was doing.

I headed back home.


Back in the classroom soon: WAC assignments, NCLB mandates, HSPA tests, UbD questions, NJCCCS. Acronyms developed by committees formed under the dull hum of fluorescent light.

I wonder what committees under sunlight would create?

But we cannot do that, we would be distracted,
we have important work to do!



If an idea seems silly literally under the light of day, then maybe it's the idea, not the light source.

So what am I going to do about this? If I am so enamored of the flats, of being surrounded by the natural world, yet teach under fluorescent lights, who's the villain?

Time for a field trip, to take my lambs to the real world, the one beyond the matrix we've created.

So here's my resolution: take a busload of kids to the shore, ostensibly to study something seemingly scientific, and let them loose among the mating horseshoe crabs this May.

November horseshoe crab


Ida blew through here, and took a good chunk of the coast with her.

Leslie and I walked down the beach to see what we could see (every one of our walks is different).

I found an old, male horseshoe crab turned upside down at the edge of the bay, digging its tail into the new sand, trying to flip itself back over.

This is an unremarkable story for most, but it mattered to me, and it mattered to him.

Finding a live horseshoe crab is a rare event in November. The fellow has descended through a few million generations of similar critters, and here he was at my feet.

I come from a much shorter line of humans (though the horseshoe crab and I have both been evolving for through the same few billion years). A few decades ago, my family left Ireland; horseshoe crabs abandoned Europe millions of years ago.

Through happenstance, I got to play with a distant cousin of mine.

If you think of life in terms of individual organisms, each with meaning, well, you'd be paralyzed--each step you take destroys life, each step you take makes life possible.

Every time I clean my pond filter, thousands, maybe millions, of critters die.
Every time I walk through the grass, I kill innumerable creatures.

If you imagine your own life is something special, more special than anything else, you're in for a bit of a surprise in the next few decades. Even you, as special as you are, are finite.

If you extend this specialness of your own life to all of God's critters, you may end up angsty sitting in a dark room, afraid to move for fear of hurting a fly. Eating becomes an act of betrayal.
You may as well be dead.

If you transfer this feeling of specialness to life itself, recognizing the joyful party that must end for each of us individually, but which will continue so long as the sun keeps shining, well, welcome to the party.

Humans are not the only organisms that feel fear, that feel ecstasy, that feel life. I have no idea what the horseshoe crab felt as it was lifted into the air, only to be gently set into the now gentle waves of the Delaware Bay.

But I know how I felt.
