Mirrors and their Manifestations
On the podcast, we hear about the life changing realization of one man's perception of himself based on what he sees in the mirror and how different his perceptions are from those of everyone else who see only his non-mirror image self every day. Throughout a long childhood of being bullied and belittled, the poor guy one day makes a crazy discovery--all these years he has parted his hair to the right, thinking it was to the left, which is how he saw it in the mirror. The very day he changes his hair part, he is welcomed into society in a way he never dreamed could be possible for him. Because a mirror reflects light, our brains receive an image that has the completely opposite orientation of what the actual object being reflected is. Now, whether or not parting your hair to the right will make you a social pariah is another topic, perhaps best answered by psychology, but this one man's trials bring up a whole slew of fascinating points and questions.
One of these questions is: Are mirror images the same as the objects being reflected? The answer lies in the thoughts and discoveries of biologists, chemists, mathematicians, authors, and philosophers who have all tackled this idea with interest. From a scientific point of view, we can talk about the physical orientation of molecules. The idea of chirality deals with molecules whose mirror images are not identical to the original molecule. We assume a mirror image is just a reversal of orientation on a page like backwards text, or a film negative, but mirror images apply differently to molecules like the all important building blocks of life, amino acids and other proteins and sugars. Here is a good time to bring in Lewis Carol's "Alice Through the Looking Glass and What she Found There." Alice asks her ever present cat, "How would you like to live in a looking-glass house, kitty? I wonder if they'd give you milk there? Perhaps looking-glass milk isn't good to drink..." In fact, it wouldn't be good to drink at all. Lactose, the major sugar in milk, is L-chiral (left-handed orientation), meaning that if you take the mirror image of the molecule, you will find that you have something completely different, D-chiral which is in a right handed orientation and is called Beta galactosidase, which is not digestible, and is what many of us lactose intolerant people know as lactase. (Lactase milk has added lactase in it to help us digest the lactose, but the difference is that all the lactose is not replaced by lactase). Mirror milk, in essence, would be a different liquid (kliM), and would be awful and indigestible!
So what do people in other disciplines say about mirrors and their manifestations? Leave a comment about things you have heard or read about.

A Day as a Tourist
The Monteverde Institute
Monteverde, Costa Rica
1400ft
Strangler Fig (Ficus) |
Yesterday we went to Curi Cancha, which is a preserve about a twenty minute walk from the institute. We decided to take a break from our work (i.e. bushwacking through dense jungle, complete with Tarzan vines, I must add, and setting transects and counting fruiting plants) and be tourists for a day. We had a guide who could mimmick bird calls very well. I kept reaching for my binoculars to look for a motmot or a quetzal that I thought was very near, but it was just our guide attempting to attract one of these territorial birds. (Sometimes you can hear a distinct call coming from the forest, and you get excited about the prospects of seeing an awesome bird, but you can't help but wonder if it is just another guide trying to attract one for tourists).
At the end of the hike, I came round a bend to see our guide hugging a huge fig tree. "Mi abuelo!" he said. Fig trees were clearly his favorite thing in the reserve. He pointed out each one we passed, as if it was the most amazing spectacle we had seen all day (some of them pretty much were). "Es increible!!!" he would say at a tree not a stone's throw from the last one we had experienced. And by experienced, I mean, standing inside the hemiepiphytes and looking up through the hollow middle and seeing all the life that consider this impressive plant to be "their bed and breakfast" as our guide put it. The strangler fig is an epiphyte in its early life, which means it does not depend on the ground soil at all to live. Instead of sending roots into the soil, it has adapted to germinate at the top of the canopy and therefore receives light that below the tree tops is a resource well competed for. Once established, it becomes a hemiepiphyte, sending large roots down to the soil, and anchoring itself around its host tree. At this point, the host tree is ancient history, as the strangler fig has cut off both its supply of sunlight and its ability to grow. The host tree rots, leaving an empty space inside and all the way up the fig tree. The effect is an entanglement of roots that have grown into each and formed buttresses and windows and criss-crossing patterns that make some of the older figs look like nature cathedrals in the woods. This phenomenon is truly a wonder to see.
Our guide's "abuelo tree" had a smooth, round section towards the bottom and it did look perfect por abrazando. "If I hug a tree all the monkeys will climb off my back, because this is my grandfather!" It was funny to see how genuinely sure of his statement he was. but i also admired his positivity--that he could find a psychological place to put his daily burdens and be mentally free of them at least for the time being. I need to find a place to let the monkeys off my back too! After some of us finished tree hugging, we swung on a long vine and felt like George of the jungle for a few seconds. It was great!
When the day was nearly over and after walking all through the busque again, on our own, and covering such topics as our plant taxonomy, JFK's assassination from a conspiracy theorist's pint of view and favourite movies, we walked back to an open field with citrus trees and purple stachytarpeta bushes outlining a gorgeous view of the sunset and the valley and water below. What I enjoyed most about our day of walking through the reserve was that we were in no hurry, had no destination, and Professor Stone would stop periodiclly to teach us about a particular plant or tell an awesome story. There is no better place to learn than outside while walking. We completed our fulfilling day by playing hacky-sack in the dazzling sunset. "What a terrible Jan Plan!" somebody exclaimed. We all hurriedly agreed and wished we were in our dorms looking out our windows at coldness, and classrooms, and computer screens.

What's so Fascinating about a Weed?
It turns out, a whole lot! I won't even get into identification, which is certainly not so fascinating for everyone, but what prompts me to write today is not simply the interesting story the weed itself holds, but rather what happens on the weed. But first, a little descriptive painting of the place I am lucky enough to go to school in:
The Autumnal Equinox doesn't arrive for another two weeks, but here in Maine, Autumn restlessly advances. It has been my daily pleasure to stroll up Runnals Hill each afternoon after classes to see the garden vegetables and wild fall blooms that make home of this windy, exposed location. Cherry tomatoes--red, purple, yellow and orange--fall into the hand at the slightest nudge and the winter squashes and rainbow kales add color to the brown hillside as they await the harvest. Queen Anne's lace, yarrows, purple clover and chicory show their delicate blooms among the spent dandelions and drying grasses of the almost-fall landscape. Milkweed, stunted by the exposure on the hillside, half heartedly relent their tightly closed pods to the cajoling breeze, as if they have forgotten their long-prepared-for cue to release their seeds.
Rainbow kale is almost too pretty to eat |
Despite an overgrowth of weeds and choking vines, the tomatoes are abundant and immensely flavorful |
The ants constantly tend the aphids and check for droplets of honeydew |
My gaze traveled up the plant, and I took note of the busy honeydew ants, which make their living by harvesting the honeydew produced by the bottom side of aphids in tiny droplets each time they stab their stylets into the flesh of a host plant. In so doing, they unwittingly provide a complete source of nourishment to the ants which vigorously protect their stock from such animals which make it their sole business to prey on aphids, namely, Lady beetles and others in the coccinelidae family. Thus, these two unlike species, aphids and ants, exist through a persistent mutualistic relationship which provides protection for one and food for the other.

Midsummer Ramblings
Maine is a beautiful state. Purple mist straggles behind as wild trees keep it tangled in their branches for an extra photographic moment each morning. Monday mornings bring frost, because I stumble out of bed early enough to see it. Looking down into the Kenebec Valley from the very top of Mayflower Hill, on the library steps (a view I saw for the first time on the tour more than a year ago) I think of why I am here. College, I have come to see, is most importantly a time and place set aside to learn about yourself. Who are you, whom do you want to become? What are your aspirations, your passions, your needs and your joys. Though all of these things haven't changed in name (I still want to be a scientist, I love animals, I want to raise a family) they do change in quality as I grow and learn.
Since that first day, I had grown inside tremendously, not changing who I am but, learning more so as to be wiser than before, and in this way, I am different in how I approach each problem and each joy alike, in my life. I look forward to the coming years.
These are just some ramblings which flow from mind to paper as I take time to reflect back on my first year of college.
A Midmorning's Pondering
I sit on a sun-warmed stone amongst garden flowers that hum with the sound of busy aviators and whisper with the delicate wings of such dignitaries as sport iridescent green coats and ruby neckties and powdery laces that flutter flower to flower. Summer is here, and the thistle family makes no small effort to be noticed by the commoners and aristocrats of the neighborhood alike, for, from the unweeded patch at the bottom of the yard their purple heads bob about in the gentle breeze, trying to outcompete the nearby wisteria I thought I eradicated last fall.

Returning
So much has changed, and my life is now completely different from when I last posted. In the next few weeks, I will share with you my recent happenings and stores of the exciting road that lead me to the present. Please come back and read often, as I will be sharing some of the highlights of the past year. Below are some teasers of stories to come:
A Stag Beetle I Happened Upon in a most Unusual Manner |
I pin hundreds of Chrysalises a Week at Work! |
One of the Highlights of my week is feeding the baby Cottontails |
I think it is fascinating to study the differences and similarities of similar species |

Raspberries
This year's spring yielded a bucketful of raspberries on our two-year-old bushes. The berries were small, but very sweat, and the most delicious raspberries I personally have every eaten!

Bumblebee Buisness
I am excited to delve into this study, as bees fascinate me. Did you know that bees leave chemical signals on petals of flowers which are later decoded by other bumblebees that come to the same flower, letting those bee know that that flower is exausted of its supply of pollen, so that no prescious foraging time is wasted? What I found even more interesting than this, was that a Bumblebee that detects a chemical signal on some surface that was made to direct it to a newfound, and profitable foraging site, can not only find the new site with astonishing precision and speed, but also, durring its flight, can even account for wind drift that it encounteres!!! Awesome right!!! I mean....I coudn't possibly dream of doing something like that without the aid of GPS, and the world at the level of a Bee is so much more complex, vast and confusing than the world we humans think we have "discovered". These little tid-bits of knowledge never cease to astonish me, and fill me with awe..but then, I get thinking to myself...well, of Course, God is a genious, of course he could make a such a tiny, simple-looking insect capable of such complex tasks.
More to come later on this topic, once I dive for a few days into my knew Bumblebee book.

Change is in the Air
I was just getting used to being a high school graduate when the college paper work came in by the ream and the postman handed me stacks of Colby College Envelopes stuffed to the poorly sealed seems with an incredulous and inquisitive look on his face. Luckily for me, I found how much I hate administration. Not only do I question Colby's need for no less than 8 documents which all ask for my name, my DOB, my age, my nationality and my signature and suspect some form of scheme to mass identity theft, but I have become seriously concerned with the lack of usable pens in my home which are desperately needed to carry out Colby's redundant and ceaseless requests for information. As Dad so profoundly noted, "You'd better get used to it because that's the rest of your life." Well, if the rest of my life is going to contain sheets of paper that request all my personal information, then yes, and thanks Dad...I'd better get used to it.
College is just eight weeks away, and so is my step up to the responsibility that comes with young-adulthood. I am excited and nervous as anything I will admit, but I am ready, and that's what counts. I look forward to the people out there that I will soon meet and who will become some of my best friends, and I look forward to learning that one thing that will give me the spark that will grow into a passion and that will fuel my interests and career for the greater part of my future.
And just on a very ponderous note, though so much will change for me in the coming months, so much will stay the same, and I find tremendous comfort in knowing that the people that are there for me are the friends and family that built me up to who I am today. Thank you for making me possible!

Rising in the East- A little poem I wrote myself
Red and yellow
Purple, gold
Fog bending colors
I lie down to get some rest
On the moist green grass
With drops of water
Refreshing on my hot brow
The day is over
But the sun shines still beneath me
Soon it will rise in the East
And that will be tomorrow.
A Particularly Interesting Prairie Home Companion Guest
Not only in church
and nightly by their bedsides
do young girls pray these days
prayer is woven into their talk
like a bright thread of awe
Even at the pedestrian mall
outbursts of praise
spring unbidden from their glossy lips.
Tension
By Billy Collins
Never use the word suddenly just to create tension.
-Writing Fiction
Suddenly, you were planting some yellow petunias
outside in the garden,
and suddenly I was in the study
looking up the word oligarchy for the thirty-seventh time.
When suddenly, without warning,
you planted the last petunia in the flat,
and I suddenly closed the dictionary
now that I was reminded of that vile form of governance.
A moment later, we found ourselves
standing suddenly in the kitchen
where you suddenly opened a can of cat food
and I just as suddenly watched you doing that.
I observed a window of leafy activity
and beyond that, a bird perched on the edge
of the stone birdbath
when suddenly you announced you were leaving
to pick up a few things at the market
and I stunned you by impulsively
pointing out that we were getting low on butter
and another case of wine would not be a bad idea.
Who could tell what the next moment would hold?
another drip from the faucet?
another little spasm of the second hand?
Would the painting of a bowl of pears continue
to hang on the wall from that nail?
Would the heavy anthologies remain on the shelves?
Would the stove hold its position?
Suddenly, it was anyone’s guess.
The sun rose ever higher in the sky.
The state capitals remained motionless on the wall map
when suddenly I found myself lying on a couch
where I closed my eyes and without any warning
began to picture the Andes, of all places,
and a path that led over the mountains to another country
with strange customs and eye-catching hats,
each one suddenly fringed with colorful little tassels.
