I was born without a left brain. Well, maybe a tiny rudimentary piece of left-ish cortex is in there. Even if the whole left brain/right brain thing is indeed a myth, all I can say is this: My brain doesn’t do the left-brain stuff. Numbers, algebra, equations, calculations, detail. Digits.
This is not to plead total incompetence. My checkbook is balanced, and I can figure tips and keep a very proper ledger of business income and outgo for tax purposes. For that matter, I did my own taxes for some time before marrying Mr. Left/Right Brain 25 years ago and succumbing to the hypnotically attractive suggestion that he’d be glad to do everything financial or mathematical for the happily ever after – which has worked out just fine.
But digital issues have bedeviled me for as far back as I can remember. In the very olden days of long road trips without car radios, a favorite family entertainment for my parents and three older sisters was “Rapid Calculations.” My father would call out numbers, as in “Start with 2. Add 4. Multiply by 6. Subtract 3. Add 17. Divide by . . .” You get the picture. My mother would determine when the game ended and everyone would write down a figure on a piece of paper to see who got the right answer. I would usually still be worrying with 36 minus three.
When I was in high school, the “dumb blond” thing was everywhere in the land and I ferociously tried not to fuel that fire. But connections with my inner left brain regularly eluded me. I blame some of it on the high school days themselves. At my beloved Henry Clay High School in beautiful downtown Ashland, Virginia, I, along with the 39 other members of the Class of ’49, hit eighth grade at a time when the school board couldn’t seem to find a math teacher. So they brought in Mac Simpson, stodgy but brainy son of the academic dean of the nearby college and a student there himself at the time. I had Mac for Algebra I and II, and maybe something else, if I ever got any farther – it’s a hazy memory. My incomprehension of basic math was utterly incomprehensible to Mac. Everything made such perfect sense to him that he was unable to back up to when that sense-making began. Thus without any grasp of the whole x-over-y thing as I launched myself into the world, my left brain simply went dark.
(I did get even, somewhat, by later dating Mac once or twice when poodle skirts were all the rage. The skirts were made out of two square yards of felt. I would agree to go to a movie, after which he would come to the house, calculate and draw the diameters of the two circles – waist and hemline – and then I’d serve him a cup of hot chocolate and say good night.)
Acknowledgment of my lifelong left-brain struggles formed the basis of my signing up, all these decades later, to volunteer for a recent program at the Commonwealth Club featuring Keith Devlin of Stanford University’s H-STAR Institute. Devlin is also President of BrainQuake, NPR’s “Math Guy,” and author of Finding Fibonacci. That last stirred something buried deep within my cerebral cortex. Fibonacci, a distant voice squeeked! The Fibonacci Sequence! Something about rabbits and multiplication! It was wonderfully comforting to know I retained a connection to the Logical Leftbrain.
Ah, to have drawn Fibonacci for Algebra I.
I might have started with Liber Abbaci (The Book of Calculation,) which introduced the western world to basic math – at a level designed for ordinary people to understand. Devlin explains that Fibonacci (whose official name was Leonardo of Pisa but there was that other Leonardo) went with his merchant father to North Africa, where trade with the far east had led to calculating prices with beads (think abacus,) something far more efficient that using fingers as was the custom in Italy. Fibonacci eventually went back home, translated the Arabic figurings into Roman numerals, wrote a bunch of books and started the whole modern arithmetic thing.
Devlin’s story of uncovering Fibonacci’s life and work through obscure library archives across Italy and elsewhere makes for a fascinating book, and his rapid-fire presentation was a treat – until the insertion of equations into his talk became necessary. Having started out on a level playing field with an historical narrative, once the numbers started popping up on the screen I began to feel again the old “Rapid Calculation” angst about being the only person in the audience still struggling to add 17.
And then Devlin tossed this bubble-popping dart: Fibonacci did not invent the Fibonacci numbers. My dimly remembered connection to the brainy lefts? Somebody else came up with that “Fibonacci Sequence.”
What’s a Right Brain to do?
“No. It’s just hard. But it’s what we do: get up in the morning, every day, and go to work at 8 AM.” Some extraordinary examples of Schumaker’s work were assembled for the latest show – creating them took about a year and a half, not all of which time was clouded in depression. My personal favorite is a piece titled “The cloud of unknowing.” Schumaker conceived the piece as a meditation, referencing the ancient (late 14th century) work of mysticism which suggests that contemplative prayer might lead to an understanding of the nature of God.
Postcards take a little more time than a phone call or email, but are a powerful way to make one’s voice heard. Especially if one is worried about human rights, the future of the planet one’s grandchildren will inherit, and the protection of our democracy.
“Critical thinking,” says author 
Dr. Willie Parker wants the moral high ground back.
Both encountered a turning point, he explains, on hearing Martin Luther King’s famous last speech which included the biblical story of the good Samaritan. In that story: after others had passed by a man in need a Samaritan stops to help. Those who passed by, Dr. King said, worried, “If I stop to help this man, what will happen to me?” Parker writes in Life’s Work that “What made the Good Samaritan good, in Dr. King’s interpretation, was that he reversed the question, ‘If I do not stop to help this man, what will happen to him?’” Immediately after hearing that, Parker writes, “Once I understood that the faithful approach to a woman in need is to help her and not to judge her or to impose upon her any restriction, penalty or shame, I had to change my life.”
You can, without undue effort, lose them to theft, ineptitude or malfunction. In the latter case – see above re my lovely Epson – the good news is that function can actually be restored in some cases.
