Mr. Sharma handed him back the old book. “Then keep reading. Because Class 9 is just the beginning. In Class 10, you’ll learn about light—reflection and refraction. That’s the story of how a ray of light gets lost, bounces off a mirror, and finds its way home.”
When the results came out, Mr. Sharma announced from the front: “Top marks: Priya, 18 out of 20.”
Dinesh felt the old sinking feeling. But then Mr. Sharma continued: “And the most improved student—from 4 to 16 out of 20—Dinesh Kumar.”
Dinesh took the book home reluctantly. That night, instead of watching TV, he opened Chapter 1: Motion .
“Sound travels through a railway track faster than through air.” – He imagined a train coming, and he put his ear to the metal rail. He felt the vibration arrive before the sound in the air. The formula was just the time it took for that news to travel.
Dinesh didn’t panic. He saw the bus. A tired old school bus. The driver was slowing down. He whispered, “It’s okay, bus. I’ve got you.” He wrote the formula, substituted the values, and got the answer: a negative acceleration, or retardation .
He finished the paper with ten minutes to spare—a first in his life.
Over the next week, he became obsessed. He started narrating every problem like a cricket commentary.
Dinesh Kumar was a boy who hated Physics with a passion that most reserved for bitter vegetables or Monday mornings. He was a Class 9 student at the Shri Ram Public School, and for him, Physics was a swamp of confusing symbols. ‘g’ was not a letter, it was gravity. ‘m’ was not for mother, it was mass. And ‘a’? It was a nightmare called acceleration.
