The Science of Forgetting: How to Remember What You Learn
“Learning is not complete when you understand something. Learning is complete when you can recall it when you need it.” Have you ever spent hours studying for an examination, only to discover a few days later that much of what you learned has disappeared from memory? Have you walked out of an examination hall and suddenly remembered the answer to a question you couldn’t recall during the test?…
Project-Based Learning for CBSE Students: How to Turn Classroom Lessons into Real-World Skills
Project-Based Learning is no longer a side activity or an “extra” classroom idea. For CBSE schools, it is becoming increasingly relevant because the larger direction of school education in India now emphasizes competency-based learning, skill education, experiential pedagogy, and real-world application rather than memorisation alone.[cite:25][cite:26] For teachers, parents, and school leaders,…
Superlubricity vs Superfluidity: Two “Super” Phenomena That Are Not the Same
Have you ever wondered whether a surface could slide without friction or a liquid could flow forever without resistance? These ideas may sound like science fiction, but physics has revealed fascinating phenomena that come surprisingly close. Two such concepts are superlubricity and superfluidity. At first glance, the names appear similar, and many students assume they refer to the same…
Superlubricity: When Friction Almost Disappears
The Mysterious World Where Surfaces Slide Without Resistance Imagine pushing a heavy cupboard across a room with just one finger. Imagine machines running for years without losing energy to heat. Imagine car engines, industrial equipment, or even tiny nanomachines operating with almost no wear and tear. It sounds like science fiction. Yet modern physics suggests that such a world may not be…
Friction: The Necessary Evil That Moves Our World
Friction: The Necessary Evil That Moves Our World Why the Force That Slows Us Down Is Also the Force That Keeps Us Going Have you ever wondered why you can walk without falling, write with a pencil, stop a bicycle using brakes, or strike a matchstick to produce fire? The answer lies in a fascinating force that works quietly around us every moment — friction. At first glance, friction appears…

What Is Physics? Scope, Branches, and How to Think Like a Physicist
Physics is the study of the natural world. It helps us understand matter, energy, motion, force, and the laws that govern everything around us. This is the first lesson in the CBSE Physics category, and it builds the foundation for every topic that follows. Introduction Have you ever wondered why an apple falls to the ground, why a stone moves when you push it, why light travels in straight…
A Journey Through the Discovery of Elements
It is a well-known fact that scientists have discovered 118 elements so far. Elements are pure substances made up of only one kind of atom, with no chemical bonding between them. The stories behind their discoveries are not only fascinating but also filled with unexpected moments. Many of them were not discovered through perfectly planned experiments, but were found by accident or emerged from…
