SPM Physics: AHA! Induction Moment — Faraday’s Falling Magnet & Humble Genius

 

In 1831, Michael Faraday asked a simple question: How can a falling magnet produce electricity? His experiments with coils and galvanometers revealed the principle of electromagnetic induction — the foundation of modern electrical science. More turns of wire meant greater change in magnetic flux, leading to stronger induced current.

But Faraday’s greatness was not only in science. He was known for humility, refusing prestigious positions and reminding the world: “I am no philosopher, but I am a hard-working man.” His life teaches students that true genius is not pride, but perseverance and character.

This comic blends physics with humanity: the formula explains the current, but the story explains the spirit.

AHA! Cosmic Moment — How Old Is the Sky? When Humans Learned the Universe Has a Birthday

 

For thousands of years, civilizations believed the universe was eternal, without beginning or end. But modern science changed that view. Edwin Hubble’s discovery that galaxies are moving apart revealed that the universe is expanding, meaning it was smaller in the past. This led to the Big Bang theory, and today scientists estimate the universe began 13.8 billion years ago.

This comic helps students see the sky not as a static backdrop, but as a cosmic timeline. Every star we see tonight is ancient light, traveling across billions of years to reach us. In Chinese culture, the sky is traditionally addressed as "Lao Tian" (Old Heaven), reflecting a deep cultural intuition that the sky is certainly not young.

Physics teaches us that the universe has an age; life teaches us to treasure our own brief moment within that vast story. When we measure this against the span of human life—especially for you, young ones currently facing the rigorous SPM examinations—our days are truly a blink in cosmic time. In this brief and fleeting life, how will you choose to make good use of it?

AHA! Cosmic Moment — Why Darkness Became the Universe’s Greatest Clue

 

Do you like the night? Perhaps it is a quiet hour for late-night reading under the lamp. I used to dislike the night, as it often brought a sense of fear, as if shrouded by dark forces. But as the years go by, I've found that night allows the mind to settle down and reflect deeply. While it is often a time that evokes melancholy, it is also the very moment closest to dawn. Even in the dark, hope can bloom—don't you agree?

This personal reflection mirrors a grander cosmic mystery: Why is the night sky dark? At first glance, it feels ordinary, but science reveals a paradox. If the universe were infinite and eternal, stars would fill every direction, and the sky should be bright. Yet we see darkness. This contradiction tells us something profound: the universe has an age, a beginning, and a story still unfolding.

Physics explains that darkness is not emptiness — it is evidence. Light takes time to travel, and the most distant stars have not yet reached us. Darkness becomes a silent teacher, reminding us that the cosmos is alive with history. For students, this comic is more than astronomy; it is a lesson in how questions lead to insight, and how even the shadows of the night can illuminate truth.

AHA! Cosmic Moment — Light-Year, The Distance of Wonder

 

Many students mistake a light-year for a unit of time. In truth, it is a unit of distance — the distance light travels in one year. Physics explains it with a simple formula: $\text{Distance} = \text{Speed} \times \text{Time}$. At the speed of light, that becomes nearly $9.46$ trillion kilometers.

This mention of distance makes one ponder: perhaps the furthest distance in the universe is not from this star to that star, but the distance from the head to the heart. Surely you can resonate with this—knowing very well that exams are coming and revision is needed, yet the mind just can't focus and the heart refuses to catch up. Hopefully, this gap isn't a light-year wide!

Yet, beyond the numbers, the light-year is a metaphor for perspective. It reminds us that the universe is vast, that every star we see tonight may be millions of light-years away, and that human curiosity itself can travel across unimaginable distances. Just as light journeys through space, our questions and dreams journey through time.

SPM Physics: AHA! Light Moment — The Little Forest Inside a Magnifying Glass (Niah Reflections)

Years ago, I captured a quiet moment of my son in Niah National Park — leaning over a fallen tree, curious about the hidden details of the forest. That small act of looking closer became the inspiration for this comic: The Little Forest Inside a Magnifying Glass.

Physics teaches us that a convex lens can magnify tiny objects when placed between the lens and its focal point. But life teaches us something deeper: when we pause, lean closer, and truly observe, we discover worlds we never knew existed. The forest was always there; we just needed to look closer.

This blog is not only about optics. It is about childhood curiosity, parental memory, and the reminder that insight often begins with wonder.
