On the Teknokrat Show aired on Focus FM, first-year Physics student at KNUST, Eric Assah, challenged common misconceptions by asserting that many everyday experiences we attribute to magic or mystery are simply applications of physics. “Switching on a light, heating food in a microwave, or even using a seatbelt in a car — none of these are magical.
They’re all physics at work,” he told host Audrey Sika Dzifa during a segment titled “Physics in Everyday Life: The Invisible Engine.” Eric explained that electrons are responsible for lighting systems and powering appliances.
“When you flip a switch, it’s electrons flowing through a circuit that produces light. The same principle applies to how a microwave quickly heats up your food.”
He also broke down how transducers inside microphones convert sound waves into electrical signals that are transmitted and modulated for listeners to hear—another process grounded in physics. Beyond gadgets and devices, he emphasized physics’ role in ensuring human safety.
“Seatbelts and motion in cars operate on the laws of inertia and momentum. Physics is what keeps you safe during sudden stops,” he said.
Encouraging fellow students, Eric added that studying physics requires curiosity and a desire to understand the “why” behind how things work. His insights sparked renewed interest in the relevance of physics beyond the classroom—highlighting how it shapes our everyday reality.
