Understanding Over Memorizing: The Day Physics Started Making Sense

There is a huge difference between reading something and actually understanding it. For years, I believed that if I read a chapter enough 

times, highlighted every important line, and memorized every formula, I would automatically become good at the subject.But reality had different plans. The moment the questions changed,all that memorization seemed to disappear, leaving me staring at a blank page.

This is especially true for physics.

Physics has a reputation for being difficult, but I don’t think it’s difficult because the concepts are impossible.I think it’s difficult because many of us are taught to remember instead of understand. We spend hours trying to memorize derivations and equations without ever asking why they exist in the first place.We know the formula, but not the story behind it.

The funny thing is, physics is happening around us every second. The phone slipping from your hand, the sound of rain hitting your window, a bicycle slowing down after you stop pedaling, or even the reason your backpack feels heavier after filling it with books—these are all physics. The subject isn’t locked inside textbooks. It’s alive in the world we live in.

Everything changed for me when I stopped asking, “What is the formula?” and started asking, “Why does this happen?”

That one question made learning feel completely different.

Instead of blindly memorizing Newton’s laws, I imagined riding a bus. When the bus suddenly stops and everyone moves forward,no longer saw it as an example printed in a textbook. I understood inertia.It became something I had experienced countless times without realizing it.

The same happened with electricity. Instead of memorizing definitions, I pictured water flowing through pipes. Suddenly, current, voltage, and resistance weren’t just words anymore. They became ideas I could visualize.

Understanding creates connections. Reading only creates familiarity.

When you only read, your brain recognizes the words. But when you understand, your brain builds a picture. And pictures stay much longer than paragraphs. That’s why we often remember a teacher who explained a concept with a simple real-life example better than pages of notes.

I’ve noticed that whenever I truly understand a topic, solving numerical problems becomes surprisingly easier. I don’t panic if the numbers are different or the question is twisted in a new way. 

Because I’m no longer searching my memory for the exact question I practiced—I understand the principle behind it.

That’s the beauty of conceptual learning. It gives confidence instead of fear.

Sadly, many students, including me at times, fall into the trap of measuring productivity by the number of pages completed. We feel accomplished after reading twenty pages, even if we can’t explain a single concept without looking back at the book.Real learning isn’t measured by how much you read. It’s measured by how well you can explain it to someone else using simple words.

Albert Einstein once said, “If you can’t explain it simply, you don’t understand it well enough.” I think that perfectly describes what learning should feel like.

Understanding also makes studying less exhausting. Memorizing everything feels like carrying a heavy bag uphill.Understanding feels like finding a shortcut. You still have to work hard, but your effort finally starts making sense.

Physics taught me something beyond science. It taught me that knowledge isn’t about collecting information; it’s about connecting ideas. Once those connections are built, formulas stop feeling like random symbols and start becoming tools that describe how the universe works.

Maybe that’s how every subject should be learned—not by racing through chapters, but by slowing down enough to understand them.Because the goal of education isn’t to fill our minds with facts that disappear after an exam. It’s to help us see the world differently.

And once you truly understand something, you rarely have to memorize it again.
