My Brain's Big Bang

        

            I stare stunned as, on the blackboard, the professor writes a scientific formula that stretches into its third line of squiggles and numbers. He spews incomprehensible narration of what sounds like chemistry, physics of light, and astrophysics.
            Was this science course listed as non-prerequisite? I must complete a single science requirement this last semester for my M.A. in Economics. When I graduate in three months, I will leave my husband, take my two babies, and move to the city where the jobs are. Without a science course, I’ll lose my investment of four years and money I can ill-afford.
            At the blackboard, the professor explains how to measure the temperature of a mass of compact matter called “a star” based upon its thermonuclear fusion, and then shows how to extrapolate in the process how old this star is and how many eons will it live before its supernova nucleosynthesis. The kinematic viscosity is helpful here, and don’t forget the hydrostatic equilibrium, of course.… No science prerequisite? When I signed for Cosmology, I thought of Astronomy. I could already point out the Great Dipper and Orion, but would flaunt new expertise about constellations at a beach party on dark summer nights….
            At recess, I stop at the professor’s desk. He is munching on a sandwich.
            “Professor, this class was listed specifically as one with no science prerequisite.”
            “Do you have high school math?”
            I nod.
            “Well then, you have all the background you need.”
            I point at the blackboard. “Not this—”
            His hand waves in dismissal. “Cosmology is fun.” He gulps coffee from his thermos. “Trust me. You’ll be okay.”
            After everyone has written their names on the yellow legal pad, introductions are made. Of the over thirty students, I am the only one who is not a science teacher, a Brookhaven nuclear lab worker, or an engineer taking this “safe” course for a graduate management degree.
            Before next week’s class I verify that none of the university’s other science classes is listed with no prerequisite. They must all be worse than this Cosmology business. Besides, this class is scheduled in the evening, off campus, closer to my house. It’s difficult to pay for a babysitter and gasoline these days when my husband is MIA, yet suing for custody of my babies, and my legal fees have already depleted my parents’ savings.
            I can only switch classes in the first two weeks of the semester. It’s now or never. My entire future is on the line. Therefore, when in the second lecture the professor explains why Einstein’s Law of Relativity does not apply to cosmos, I plant myself in front of his desk at recess. I wait until he passes around the yellow legal pad for all to sign attendance.
            “Professor.” My eyes filled with tears. “I don’t know why Einstein’s Law of Relativity works on our Planet Earth. How can I figure out why it doesn’t elsewhere? This class is for scientists.”
            “High school math is all you need,” he repeats.
            “If I don’t drop out today, I won’t be able to get into another course.” I place in front of him the printout of the school program. “Can you suggest another one for a lay person?”
            “Look.” He picks something caught between two molars. “I believe that if you just sit in class and listen, you’ll get it.”
            I am certain that if I lay in the river for months I won’t turn into a crocodile. I shake my head. “No way.”
            “I’ll make a deal with you,” he says. “If you just show up for all classes, I’ll give you a B.”
            Just like that? “What about the quizzes and the semi-final and final exams?”
            “You’ll get a B. Just for attending.”
            Maybe it doesn’t look good for him when people drop out, but I am willing to buy the arrangement. Off the hook, I take a jaunty jig to my seat.      
     For the rest of the semester, I ignore the two multi-choice quizzes in which I fail, followed by the mid-term. I also do not attempt to decipher the formulas the professor scribbles on the blackboard. I am light-years away from caring what happens to helium at 40,000 degrees Fahrenheit or calculating the velocity of matter gravitating toward a nebula (what’s that?) by converting the heat volume to light units. Or perhaps, the reverse deduction? Oh, yes, all these pieces of data also tell us how old the star is. Or is it a planet? Calculate it all, please, with your high school math. Did I mention distance? It can be extrapolated from this data if we also add the color of the light of a given star because it can be deduced from its electromagnetic spectrum….
            That is Cosmology. The science to top all sciences because it includes all of them.
            I show up every Wednesday at seven in the evening and sit down to doodle. The only thing I learn is that quantum mechanics and molecular physics are also incorporated into the formulas on the blackboard. It doesn’t matter, really. I will get a B. At recess, I sign my name on the yellow legal pad, then leave and go home to my babies and to study for the other classes I must complete. Actually, my home is no longer “my home,” as I have escaped domestic violence, and we now sheltered in someone’s basement. Soon, I’ll finish this semester and begin a new life far from here.
            Three weeks to finals. A judge with an unabashed dislike of women wishing to liberate themselves grants me only twenty-five dollars a week for the three of us. If not for the kindness of strangers, we’d starve. I polish my resume and start applying for jobs.
            I stop at the professor’s desk. “Remember our agreement?” I ask. “I don’t need to do well on the final. I get a B.”
            “Oh, no,” he replies. “The agreement was for you to sit in the classroom. You left every week at recess.”
            The hair roots stand on my head. A split second later, the blood drains from my temples. “You can’t do this,” I whisper. “I can’t graduate with less than a B.”
            “Sorry. That was the deal.”
            I begin to hyperventilate.
            His sympathy must be genuine because he says, “Look. If you get an A, I will ignore all these failed quizzes and the mid-term.”
            “An A?” I blurt like a dimwit.
            “I’m giving you a new deal.”
            I walk away in a daze. My celestial fantasies of a life outside the doomed marriage is sucked into the kind of black hole the professor talked about, some mass so compacted that nothing escapes from it, not even light.
           
            There is no choice. I must get an A in Cosmology as if my life depends on it, because it really does.
            I go to the public library and plant myself in the children’s section. I begin reading first-grade books about planets and novas and black holes. I study the colorful pictures of the expanding universe and read about stellar dynamics and galaxies and what they are made of. Junk, really, clouds of particles and gasses—hydrogen and helium mostly—that under high pressure change from one chemical composition into something else whose density can be measured using luminosity and temperature.
            Equipped to put it all in some context, I move to middle-school level books. I should be able to learn material suitable for a ten-year old, even a fourteen-year old. The Big Bang theory; the Hubble telescope; white and red dwarfs; isometric theory; gravitation; black spaces; nuclear fission. Artists’ renderings are very helpful. I begin to get it. Presented in a way I can understand, the material piques my curiosity. Suddenly, I even enjoy it. Coming out of the library late on a moonless night, I look at a pinprick of a star in the sky and know that I am staring at history: this light left its source eons ago, but only now it reaches my human eye here on earth. How awesome is that?
            I am soon in the library’s high school science section, then check another library to make sure I cover all available easy books. I have no idea what material was taught in class; to be on the safe side I read everything.
            By the end of an intensive three weeks, I close the last page of The Encyclopedia of Cosmology, having read every value in it. To my bewilderment and surprise, I comprehend it all.
           
            The transcript of my grades arrives. Scared, I hold the envelope in my palm. I’ve already moved my family. I glued stickers of galaxies and constellations on the ceiling of my babies’ new bedroom. My lawyer guaranteed the first two months’ rent, uncertain how I would pay it. I’ve taken the first semi-decent marketing job offered. The unknown, the responsibility, and the fear bear down on me so much that I’ve lost the grip on who I am.
            I open the envelope.
            Cosmology: A.
                       
            In the decades that have passed since my last exam, I’ve stared many times into the depth of the Milky Way. I know that our galaxy is merely one of hundreds of billions other galaxies, but rather than feel small, I feel victorious: I explored the farthest reaches of our vast, ever-expanding universe and came out a winner.

Au Revoir, Paris

(This blog was written at the end of my sojourn, but the long hours in class and café conversations—and even longer walks—took their toll on my poor spine and kept me away from the computer. Now at home in NY, I am struggling to recover.)

             French uses three different words for “Goodbye.” Adieu, a strong, decisive finality of parting. Au revoir, as in “see you around,” or “see you again,” and À bientôt, indicating a tight time frame of “see you in a jiff,” or at least “later today.”
            I am sitting outside a patisserie on Rue des Écoles, so named for the various Sorbonne colleges that have made this street famous. In fact, the Latin Quarter was once the home of the language that dominated the world of science. 
            In some magical way, this intellectual history should seep into my brain, the way Parisian glamour must come to inhabit my skin. But the pigeons picking at my feet, the city-lending bicycles, the passing middle-aged couples—American retirees making Paris their home for a few months—offer no hint of such osmosis. Still…. The romance of Paris is forever present, pulsating in the sights of the brasserie across the street painted in red; in the ornate carvings on the building next door, with filigree faux balconies; and in the glimpse of a man who comes out of the patisserie carrying three unwrapped baguettes.
Rue Moufftard

            Through the door left ajar behind me whiffs the voice of the chatting proprietor. The tattooed, gray-haired pig-tailed, muscular man might have been one of the students who in 1968 rebelled right on this very street, flinging cobblestones at the police. His butter-filled, flaky croissant makes the transition to the world of working middle-class adults worthwhile. 
            Today is May Day, and several blocks away at l’Odeon, one of the parades fills the streets. The French take this labor day seriously. All shops and services are closed. People buy one another the flower that symbolizes the day, Lily of the Valley, muguet. A Frenchman asked me to compare Israel’s and France’s socialism. My response: “Israel started as a socialist country but has moved away from this ideology, while France is sinking deeper into socialism.”
            It is very cold, in the upper 40s, the kind of temperature I would certainly not tolerate in NY, sitting outside with my deca crème, (decaffeinated coffee,) not even under a space heater that dries my hair but leaves my toes to freeze. This afternoon I am signed up for a walk in the path of Ernest Hemingway, but the persisting cold spring is discouraging. The urge to grab more of every moment is strong, though. There is always another public art to look at, another alley to discover, another surprising storefront not to be missed. There are prints to be leafed through at art galleries, there are French words pouring around me to be caught and mulled over. There are events, and people and blooming flowers. Did I mention shopping?
Store window--of an exterminator....
            A major debate has been raging here about what we in the US call "Same-sex marriage," but they call "Mariage pour tous," (translated: Marriage for all.) Against demonstrations and heated TV discussions, the parliament has passed the law this week. In my French conversations I explained the nuanced difference in the name: While in USA "same-sex" marriage means that two people of the same sex can (or should be allowed) to marry, "marriage for all" includes plural marriage! This oversight might have serious implications given France's growing Muslim population. Some immigrant families arrive with multiple wives, but many such unions are formed within the community in France against the law. 
            Having multiple wives in the French socialist environment that provides generous benefits for children greatly profits the man. While wives number two, three or four  appear to the authorities as single mothers and therefore are entitled to a host of benefits, the reality is that in their strict, honor-bound society these women would have been killed for just speaking with a man, let alone for bearing children out of wedlock—unless their union is indeed recognized internally by their tradition. It is left to see when these marriages will be claimed legitimate under the new law of "marriage for all."
            In forty-eight hours I will be at the airport, about to board the plane that would deliver me back to my life in New York. I came here to immerse myself in French. I took dance classes and played Mah-Jongg in French, and had been quite certain that my former fluency would pop up, the way memories resurface. But through the long hours of classes and equally long hours of conversations I came to the disappointing realization that while my language skills have indeed improved, it must be all relearned, verb by conjugated verb. My facial muscles must be retrained. (Research shows that French have a particularly strong and animated upper lip.) Had I really known all these idioms and word turns? Had I once talked as fast as the locals? Had I understood French films? These past four weeks I’ve also learned to appreciate the contribution of the two subsequent generations that have since my youth enriched the language—or butchered it, as their critics claim.
            With holes in all my socks and debilitating back pain, but light in my heart, I return home. Au revoir, Paris, but not Adieu.
