Transformations

Anonymous — Wed, 29 Feb 2012 01:47:00 GMT

Yesterday we fooled a few bacteria into taking in some jellyfish DNA, and now they fluoresce green. Tomorrow I will take a few colonies of these and give them what we all need--food, shelter, and a little security, and I'll get a few million more by Thursday.

This has become old hat in high school biology classes, but it still blows my mind, as it should.

We are all God now. You may laugh, and I can temper this with some off-hand remark, but we're not the same critters we were before we started transforming lifeforms. That we do this with indifference makes it seem surreal.

(I wanted to jump up and down and scream in delight and fear--"Look what we've done!!!!" And, OK, maybe I did, just a little bit....)

***

A few planets are lining up this week, and a few folks are excited. So excited that you can go online and see them.

That planets are visible naked eye is pretty cool, and that they wander against the background of stars even neater. Indeed, that's where the word "planet" comes from--planasthai, "to wander."

To stare at one naked eye, though, is not particularly exciting. They flicker less than stars, and are quite bright, but, well, um--they look like stars.

We have made looking at planets a check list event, a commodity, an "event" simply because it's an event.

A lot of folks cannot fathom anymore why that bothers me, so I guess that puts me in the crank category. A lot of folks cannot fathom what they even want.

Maybe the point of education is to learn what you want, to figure out what's worth seeking. I'm pretty sure it's not to pass a standardized test.

***

Most of my students have never stumbled upon a flickering comb jelly, flashing electric blue as it lies dying on the beach. I have, and I wondered--who was meant to see the light?

I can change the way light is reflected off bacteria, light meant only for a few other humans to see, to reflect our glory of ourselves as we play God.

Some comb jellies flash an electric blue when disturbed, presumably to distract predators. This makes sense, a logical reason to expend energy, fit for our mechanistic view of the world.

Yet when I squat by a dying critter, the rhythm of the wash of waves running through my ears, the salty smell of the dying in my nostrils, the soft forgiving warm and wet sand caressing my feet, this single jelly flashing its last three, brief pulses of light on the edge of the bay matters to me, and I do not know why.

I only saw it because I happened to be there--and it would have mattered even if I had not seen it.

I have no opinion on the existence of God--my people said He is unknowable, and I, to their chagrin, took them at their word. I do not truck with what I cannot know.

But I do know this--we cannot know (and can never know) what we pretend to know today. Hubris does not require the existence of gods.

Tomorrow I will be the destroyer of earths as I kill the same bacterial cultures we worked hard to create. I will pretend this does not bother me.

***

As for the planets, if you think it's worth staring at them online, I have a few other parlor tricks that may interest you.

Cristoforo Colombo used a similar parlor trick to fool the locals of what is now known as Jamaica. The locals had supported Colombo and his crew, but were (understandably) a little annoyed at the murderous actions of some of his crew. Colombo knew of an impending lunar eclipse predicted by Regiomontanus many years before. He attributed the eclipse to the Christian God, the same God Europe used to justify slaughtering those who knew my bay before me.

Stories matter.

Still, a lunar eclipse is about as exciting as the planets lined up in late winter--a parlor show. That they exist (and that we figured out what those points of light mean) are the stories worth knowing.

So tomorrow, an hour or so after my bacteria break down their last molecules of sugar, I will wander outside Bloomfield High, take a look west, and see the string of planetary pearls that got so much attention this week.

Then I'll walk home, knowing I am among the luckiest men alive, feeling the earth below with every step that takes me home.

Hokey smokes! Fluorescent bacteria!!!!

The end of winter

Anonymous — Sun, 27 Feb 2011 23:38:00 GMT

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

Anonymous — Sat, 26 Feb 2011 21:31:00 GMT

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.

Last harvest

Anonymous — Sat, 22 Jan 2011 18:22:00 GMT

Then the LORD God formed a manfrom the dust of the ground and
breathed into his nostrils the breath of life, and the man became a living soul.

As I was poking around the classroom garden yesterday, getting the plants ready for the weekend, I found a pea pod dangling from a tiny pea vine.

The child who nurtured it will get "extra credit"--I used promises of points to get the some of my lambs 'interested' in putting dried peas into icky peat moss. She won't remember the points. She will remember the pod.

I hope she remembers the countless times she breathed on her hand--carbon dioxide and water released deep in her cells. Our plants are built on the carbon backbone of our exhaled breaths.

I do not pretend to know anything of God or gods. I enjoy reading the words of cultures past, to see what they saw when words were still so young that they were used carefully.

I can recognize grace, though--a pea pod given to us for the cost of our breath and a little bit of water.

***

I just came in from picking a few scrawny Brussels sprouts from very chilly plants--two of them now gracefully bend towards the ground, forming archways, seemingly honoring the earth that bore them, the last harvest of last spring's garden.

The sun is returning, slowly, so that our exhaled carbon dioxide can be used again, with grace.

I can show the kids the graph above--the annual wobble in CO₂ levels reflects the dance between the light of life and the ensuing darkness each winter.

Chloroplasts and mitochondria, ancient critters in cells that keep much of the living alive, work in tandem. Chloroplasts capture the energy of the sun in sugar, and mitochondria release the energy as the sugars tumble back to water and CO₂.

A child feeds on the lies of our culture. Magic erupts from screens, voices erupt from wire. We are consumers on the infinite, and we tell the children lies because we believe them ourselves.

She memorizes the photosythesis equation without understanding, because we tell her she must, in order to graduate, in order to get to college, in order to earn money, in order to eat.

A tiny pod just might put a tiny seed of doubt in her. It came from nothing, or so it seems.
It's tangible in a way photons can never be, no matter how thin the computer, how bright the screen.

***

So I will keep teaching about electron transport chains and ATP and things that can be tested with no more than a scantron and a pencil. I get paid to do this, and I enjoy it.

Our classroom garden provides the real lessons. Heads of wheat are erupting from plastic bottles, impossibly yellow squash flowers lean over plastic trays, and the peas keep wrapping themselves around everything in their path.

Not everything thrives--some of the children get quiet when their seedling wilts, a few get angry. There are always more peat pots and seeds in the back, and eventually another seed gets planted, converting our breath again to the living.

Biology.

Do not confuse grace with religion, nor technology with science. I know nothing. None of us do.

Crocuses and clams

Anonymous — Sat, 08 Jan 2011 22:41:00 GMT

We're a few weeks away from the crocuses. They know the sun is coming back. I do not know how they know but they do. Soon green fingers will break through the corms.

Meanwhile, my clams have settled in for the winter. Not deep, maybe 2 or 3 inches deeper than July, but still deeper, clammed up tight, waiting for the water to warm. Deep for a clam, though.

We still have a few stalks of Brussels sprouts growing, still with a few tiny sprouts left.

At this moment, the tide is just starting to rise again on the mudflats, under a crescent moon dancing between wintry clouds low in the west. The clams are there, under the black water glistening from the sliver of moonlight, as they have been before we came, as they will be when we're gone.

In a few more hours, a few feet of water will rise over the clams, then recede again before dawn.

***

We can teach about tides and the moon, we can talk of gravity, but until a child wrestles a clam from the mud, she knows nothing about them.

Most of what we teach, or pretend to teach, means nothing to a child, but often, sadly, nothing to the teacher as well.

I know of tides, but not the taiga or the tiger.

I know of quahogs, and reasonably well, but my words and pictures cannot replace an afternoon on the mudflats, the pungent sweet smell of life mingling with death, jolting young noses more familiar with Amber Romance and Axe.

A single afternoon on the flats can be ruined if I emphasize the abstract, especially to a generation that knows only the abstract. So I will pretend to care about mantles and siphons and the economic importance of hard shell clams while I hope that a few of the children get curious about this unknowable universe we've kept hidden from them.

And for the next few weeks, I am trapped in their world, until the crocuses come back.

Thanks to PSE&G, about 150 young adults will get to spend a day on a tidal flat in May.

On balance

Anonymous — Fri, 05 Nov 2010 11:08:00 GMT

Theology alert--feel free to jump in....
This was inspired by Father Sean and Brother John and the Reverend Scott.

Balance.

We need balance in our lives. Overwhelmed? Seek balance.

An innocuous philosophy--who could possibly be against balance?

A madman in the back wildy waves hand--and (again) I get sent out of the classroom.

***

The light is failing. Local carbon dioxide levels will rise until late May now, when resurrected plants start reconstructing the molecules back into something we can use again next winter. CO₂ and H₂O, carefully bonded back together into strawberries in June, peaches in July, corn in August, wheat in the September...little left now but the kale and the Brussels sprouts.

Breathe on your hand--you can feel the moisture, the breeze of molecules brushing your hand.

If God can be found, She will be found in the chloroplast, Her heart made of rubisco, the enzyme that puts us together, the most common protein in our known universe. She carefully holds a tiny molecule of carbon dioxide, three atoms of nothing, and glues them to life.

Heart of God?

She takes her life, her energy from the sun. Three times a second, another molecule of CO2 pressed together to a molecule of life, over and over and over again.

Rubisco is everywhere, in every green leaf, and as the leaves of summer fade into fall's glory, She leaves us. We start to drown in our own CO2, waiting for Her return, as She has, as She will. (That's called faith.)

***

You cannot balance a lifetime. You can dance, jump for joy, cringe in fear, curl up, scream, love or hate. There is no balance for love, for fear.

A well lived life is not one where you've balanced your fears with your joys, your love with your hate.

A "well lived" life makes no sense. You cannot "lived"--you can only live, now, this moment. Either the amygdala or the cortex rules a moment. We pretend we can string together moments, we hold on to memories, to words, to pictures, to myths of eternity, and we miss the obvious.

The here and now.

And we wonder why it's hard to teach children in a classroom....

***

A couple of soldier flies erupted from our class terrarium last week. Unexpected. Large critters crawled out of the thin litter layering the glass bottom. The yellow bar splashed on their legs with their waspish wings and fluttering antennae screamed danger. My cortex knows they're harmless, my amygdala makes my fingers stutter when I pick one up.

The last few days a half dozen more came from the same dirt.

When I opened the top to feed my sowbugs yesterday, two flew out and headed for the window. They only live a day or two as adults, and they had been trapped for hours in the terrarium. They flew fiercely, full of desire, and crashed right into the glass.

Instinct, true. Fixed action patterns with proximate and ultimate causes. Memorize this, children, pay $87, and earn your AP Biology credit.

We never speak of desire in other creatures. Of wants. Of needs.

The soldier fly carcasses will sit on the sill until my students return on Monday. I will ask them how they got there. Then I will ask why.

We all need what rubisco gets us--we all feel desire. It's why we burn our energy even though we know December's coming.

***

וייצר יהוה אלהים את האדם עפר מן האדמה ויפח באפיו נשמת חיים ויהי האדם לנפש חיה׃

And the LORD God formed man of the dust of the ground,
and breathed into his nostrils the breath of life;
and man became a living soul.

We think we're sophisticated and learned and (the worst conceit of the three) immortal. We gorge on the fruit of the Tree of Knowledge and forget that we are closer to the soldier flies than we are to rubisco.

I do not know who wrote the Hebew Bible, and I do not know which of the 47 men chosen by King James translated Genesis 2:7, but there's been a huge misinterpretation of "soul" in the last few hundred years.

The soul, at least according to the Words allegedly governing the actions of the dangerously powerful here in the States, is not separate from the dirt. Our "stuff," the polymers of proteins, our layers of lipids, our DNA, our essence, is our soul.

We are mortal and finite. We are living souls, dependent on rubisco, dependent on unimaginable events in the heart of the sun, hydrogen to fusion, mass to light.

You want your children ready for the world of humans, raise them under artifical light. Keep them planted in front of monitors. Feed them impossibly perfect fruit. Keep them shod. Pump them full of music made by machines. Surround them with images of the "perfect" human, and demand they become one.

Don't talk to me about balance.

We are training our children to avoid the window pane, to stay safe, to gaze at the world outside, to create stronger panes. We don't want to see them hurt. We cannot imagine their last agonal breaths.

Me? I want my children to crash into the glass, and if they're bloodied lying on the sill, to get up and crash into it again. Again and again and again.

3 billion years of desire got us to here; a few hundred years of playing God has reduced us chasing photons on screens, practicing religion disconnected from the wiser elders who wrote texts we refuse to read, to believing we are in control.

I may be unhinged, but I am not as unbalanced as anyone who believes in balance.

The sun that sustains me has been dropping lower into the sky day by day, the plants that feed me have lost their leaves, the bees I adore have gone. I am a man of science, I have a good idea why this is so.

I am also a man of faith--faith that the sunlight will return, and that rubisco will return with it come spring.

Photos are mine and Leslie's.

On ignorance

Anonymous — Sat, 07 Aug 2010 21:56:00 GMT

The sun slips toward the water. The breeze brings with it the thump-thump-thump of a karaoke box from Harpoon Henry's, a shore joint just over the dune. We barely here it over the waves, but we hear it.

I wandered into the muddy bay, up to my waist. The water is a little chilly, but my toes, buried in the sand, are warm, leftover heat from the sun hitting the beach before the tide rose.

A jelly comb drifts by, its edges marked by iridescent waves. A small crab scurries over my foot.

I am alive, as alive as I can be, and so is the jelly comb.

***

Tonight we're eating basil and cucumbers from the garden; yesterday we ate the tomatoes, and before that, the beans.

The tide rises, the tide falls, an incomprehensible volume of water moving twice a day a stone's throw from here.
Why? The moon, the sun, gravity....

Why? Well, the moon and the sun pull...

Why? Good Lord, child, no one knows why, no one....

***

The standardized tests allegedly test what we know. I want a test that tests what we don't know.

If our culture collapses in the next generation or two (and there are signs it may do just that), it will not collapse because of what we think we know.

It will collapse because of our stubborn refusal to acknowledge what we cannot know, or what we pretend to know.

If you watch a comb jelly even for a few moments on a late afternoon in August, really watch, allowing yourself to be washed by the beauty of a creature as foreign as Jupiter, you will (if only for a moment) grasp that we know nothing at all about anything beyond our human conceits.

And if you see the same creature glow at night, you might even worship it.

***

What would a test like that look like? How do you test for true ignorance?

Ignorance is easy to feign--some kids are motivated enough to study arcane ideas for hours in order to do well on tests that will get them ahead in life.

A child can be coerced into memorizing the equation for photosynthesis. Few kids grasp the significance, and why should they in a world dominated by lust and image and inopportune zits? It cannot be taught in a day, a week, a unit.

I could spend weeks on the sun alone, a magnificent star, a sphere of plasma. I could create plasma in the classroom, get my lambs excited about energy and matter as the boundaries between the two dissolve. Nothing here happens before the sun's existence.

But we do not worship the sun anymore.

We worship our words, our buildings, our cleverness.

So how would you assess ignorance, the awareness of how little we really know?
And should teachers spend more time showing what we don't know, instead of what we do?

The sun photo gets credited to NASA--one massive solar flare hurled towards Earth, and it's lights out.

Lammas again

Anonymous — Sun, 01 Aug 2010 11:34:00 GMT

Yep, same as last year--I like the rhythm of the year.

The sunlight diminishes perceptibly now. The plants know.

The past week we've eaten deep purple eggplants and bright pink brandywine tomatoes, yellow summer squash and green-and-red striped beans. Today we will pick basil for pesto, some for tonight, some for February. A bowl full of ripe blueberries waits for us, sunlight incarnate.

But the sunlight is dying, and the plants know.

We do not speak of religion in class, at least not formally, though students will occasionally ask religious questions, and I will deflect them. I explain that some things cannot be known through science, and that what I believe beyond the limits of science falls outside the province of class.

In class we talk of light and hormones, photoperiods and abscisic acids, to explain how plants know. We talk under the hum of fluorescent lights, time marked by defined blocks of time. In class, September light is exactly the same as February light, and class is always 48 minutes long, no matter where the sun sits.

Sunset today marks the start of Lammas, or Loaf Mass Day--joy for the harvests that are coming and regret for waning sunlight. Lammas used to be celebrated--the first wheat berries of the year were ground into flour and baked into bread offered in thanks, some used for Communion, some for the feast that followed.

We thank God (or Tailtiu or Lugh or some other forgotten gods)--harvest time reflects death and grace, whatever the culture. Death and grace feel foreign in the classroom, indeed foreign in our culture. We pretend, at our peril, that life is linear.

Lammas falls halfway between the summer solstice and the autumnal equinox. The days are shortening, winter is coming. Until you feel the seasons in your bones, until you follow a grain of wheat from the ground to plant to bread to you then back to the ground again, the modern myths may be enough.

Science can explain why plants produce fruit when they do, and I can teach the steps. We can test whether a student learns what I present, and the students that do this best have access to all our culture offers.

You can become very powerful, very rich, without knowing grace. You can go far in life if blessed with intelligence and beauty, degrees and citations, without ever knowing what a wheat berry looks like, without ever kneading a lump of flour and water and yeast into glistening dough.

In the end, we don't know much, and may never know much. We can, however, recognize grace. We might not grasp it rationally, but we we can grasp it--a good reason to celebrate Lammas.

6th Great Extinction? (Don't scare the kids....)

Anonymous — Mon, 05 Jul 2010 00:27:00 GMT

What do you teach a young adolescent? How much of the truth do you dare bare?

We are in the midst of the Sixth Great Extinction. Technology got us here, and I have my doubts it will get us out.

I have faith in life--creatures live in the deepest depths of the oceans, in scalding hot springs, deep within the Earth's crusts will survive whatever we might do in the next few generations.

I have faith in the sun--it will continue to beam on us for a good few more billion years.

I have faith in love--not that it will save us, but that we're redeemable, all of us.

I do not, however, have faith that the current culture has any inclination towards self-preservation. A bumper sticker on a Prius will not save us, no matter how near zero its emissions may be.

And here on the Fourth of July, in a land blessed with water and soil and a temperate climate, on a day marking the signing of the Declaration of Independence, most of us would starve to death without some sort of cash flow.

The man credited with writing the Declaration of Independence also wrote these words:

The earth is given as a common stock for man to labor and live on. If for the encouragement of industry we allow it to be appropriated, we must take care that other employment be provided to those excluded from the appropriation. If we do not, the fundamental right to labor the earth returns to the unemployed... It is not too soon to provide by every possible means that as few as possible shall be without a little portion of land. The small landholders are the most precious part of a state.

What do you suppose he would say in my classroom today? In your classroom?

Yep, clams again....

Anonymous — Sat, 24 Apr 2010 21:54:00 GMT

Today I dug up a couple dozen quahogs, half of which ended up on the table tonight. I also found a gold ring while raking for the clams. Which is worth more?

Aside from the nominal $10 fee I pay New Jersey, for the privilege of printing out of piece of paper that keeps me from paying more, the clams cost me nothing but a little exercise.

Nothing.

The ring cost someone some dollars. It has initials on it. I found it about 6" deep. I could sell it and get me some dollars for it. Someone was paid money to get it from the ground, someone else was paid money to put the monogram on it. I think maybe I'll just toss it back.

One of the clams had a deep purple patch on the inside, the kind of purple you see just before dusk ends. Purple is the last color we can see of the visual spectrum. Beyond purple, ultraviolet, then X-rays, then gamma rays. Purple is as much EMR excitement as we can safely tolerate.

Gold falls somewhere in the middle.

Would you trade your ability to see purple for a ton of gold? Do you even consider doing the calculations?

***

My uncle got the first little neck today. First one of the year.

We were trying out a new tide flat today, and I was not sure how we'd do.

I am an experienced clammer, and while I raked up a bunch of steamers, I could not find a little neck. Once my uncle did, though, I found a bunch more. I could not find them until I believed they were there. Once I believed they were there, I could not believe I missed them before that.

A huge part of science is framing the question, framing your observations. Our ability to see things is proportional to our belief that those things exist. We are very good at not seeing things we do not want to believe exist.

My grip on reality is tenuous, but I suspect it is no more tenuous than most of us.

A few hours ago a little neck siphoned sea water, as it has for 5 or 6 years now. It stripped organic compounds from the water, and it grew. That same clam is now somewhere between my stomach and my large intestine. Words can only defile the relationship I have with the clam, with the plankton the clam filtered yesterday, with the sun's energy captured by the plankton two weeks ago while I fretted about the school budget cuts.

That I can even think such thoughts depends on my ability to convert the clam's clamminess into glucose, to feed my brain.

Gold can't do that.

This was my 500th post. I'm thinking of retiring soon....
