I began to study trigonometry. There was solace in its strange formulas and equations. I was drawn to the Pythagorean theorem and its promise of a universal—the ability to predict the nature of any three points containing a right angle, anywhere, always. What I knew of physics I had learned in the junkyard, where the physical world often seemed unstable, capricious. But here was a principle through which the dimensions of life could be defined, captured. Perhaps reality was not wholly volatile. Perhaps it could be explained, predicted. Perhaps it could be made to make sense.
The misery began when I moved beyond the Pythagorean theorem to sine, cosine and tangent. I couldn’t grasp such abstractions. I could feel the logic in them, could sense their power to bestow order and symmetry, but I couldn’t unlock it. They kept their secrets, becoming a kind of gateway beyond which I believed there was a world of law and reason. But I could not pass through the gate.
Mother said that if I wanted to learn trigonometry, it was her responsibility to teach me. She set aside an evening, and the two of us sat at the kitchen table, scratching at bits of paper and tugging our hair. We spent three hours on a single problem, and every answer we produced was wrong.
“I wasn’t any good at trig in high school,” Mother moaned, slamming the book shut. “And I’ve forgotten what little I knew.”
Dad was in the living room, shuffling through blueprints for the granaries and mumbling to himself. I’d watched him sketch those blueprints, watched him perform the calculations, altering this angle or lengthening that beam. Dad had little formal education in mathematics but it was impossible to doubt his aptitude: somehow I knew that if I put the equation before my father, he would be able to solve it.
When I’d told Dad that I planned to go to college, he’d said a woman’s place was in the home, that I should be learning about herbs—“God’s pharmacy” he’d called it, smiling to himself—so I could take over for Mother. He’d said a lot more, of course, about how I was whoring after man’s knowledge instead of God’s, but still I decided to ask him about trigonometry. Here was a sliver of man’s knowledge I was certain he possessed.
I scribbled the problem on a fresh sheet of paper. Dad didn’t look up as I approached, so gently, slowly, I slid the paper over the blueprints. “Dad, can you solve this?”
He looked at me harshly, then his eyes softened. He rotated the paper, gazed at it for a moment, and began to scrawl, numbers and circles and great, arcing lines that doubled back on themselves. His solution didn’t look like anything in my textbook. It didn’t look like anything I had ever seen. His mustache twitched; he mumbled. Then he stopped scribbling, looked up and gave the correct answer.
I asked how he’d solved it. “I don’t know how to solve it,” he said, handing me the paper. “All I know is, that’s the answer.”
I walked back to the kitchen, comparing the clean, balanced equation to the mayhem of unfinished computations and dizzying sketches. I was struck by the strangeness of that page: Dad could command this science, could decipher its language, decrypt its logic, could bend and twist and squeeze from it the truth. But as it passed through him, it turned to chaos.

I STUDIED TRIGONOMETRY FOR a month. I sometimes dreamed about sine, cosine and tangent, about mysterious angles and concussed computations, but for all this I made no real progress. I could not self-teach trigonometry. But I knew someone who had.
Tyler told me to meet him at our aunt Debbie’s house, because she lived near Brigham Young University. The drive was three hours. I felt uncomfortable knocking on my aunt’s door. She was Mother’s sister, and Tyler had lived with her during his first year at BYU, but that was all I knew of her.
Tyler answered the door. We settled in the living room while Debbie prepared a casserole. Tyler solved the equations easily, writing out orderly explanations for every step. He was studying mechanical engineering, set to graduate near the top of his class, and soon after would start a PhD at Purdue. My trig equations were far beneath his abilities, but if he was bored he didn’t show it; he just explained the principles patiently, over and over. The gate opened a little, and I peeked through it.
Tyler had gone, and Debbie was pushing a plate of casserole into my hands, when the phone rang. It was Mother.
“There’s been an accident in Malad,” she said.

MOTHER HAD LITTLE INFORMATION. Shawn had fallen. He’d landed on his head. Someone had called 911, and he’d been airlifted to a hospital in Pocatello. The doctors weren’t sure if he would live. That was all she knew.
