Physics Teaching

My Online Course Journey and a Guide to My Favorite Tool, OBS

My move from oCam to OBS became a crash course in scenes, audio, and output settings—practical lessons to make your own course recording smoother.

Air Resistance, Terminal Velocity, and Rainfall

A raindrop in ideal free fall could reach 153 m/s—so why doesn’t it? Follow the physics from air resistance to terminal velocity.

[Scientist Biography Series] Galileo: His Life and Free Fall

Galileo never finished university, yet returned to teach and kept challenging authority. His choices and controversies offer a fresh way to understand free fall.

[Scientist Biography Series] Aristotle: Learn Philosophy, and You Can Learn Anything

Aristotle’s physics was later revised, but he once tried to explain the entire world through one intellectual system. His interdisciplinary life shows how knowledge advances through correction.

[Scientist Biography Series] Robert Hooke: Master Mechanic and Hooke’s Law

Hooke was far more than F = kx: cells, mechanics, architecture, and a scientific rivalry with Newton whose later legends still need fact-checking.

[Scientist Biography Series] Newton and the Apple

An apple did not knock universal gravitation into Newton. Follow the real story from his plague-era breakthroughs to the calculus dispute.

[Scientist Biography Series] Kepler and His Dream of the Heavens

A song recalled Kepler’s name, but refusing to ignore eight arcminutes is what turned perfect circles into elliptical orbits.

[Scientist Biography Series] Archimedes Was More Than Just the Naked Guy

Everyone remembers Archimedes running naked, but his real story spans buoyancy, levers, mathematics, siege engineering—and famous tales that may not be true.

A Gentle Introduction to Differentiation

From secant lines to tangent slopes, build a visual understanding of differentiation, limits, and instantaneous rates of change in physics.

A Gentle Introduction to Integration

Understand integration through finer partitions, sums, and limits—then see how it describes accumulation in physics.

Differentiating Trigonometric Functions

Derive the derivatives of sine and cosine from two key limits, then see how their four-step cycle connects to simple harmonic motion.

How Simple Harmonic Motion Really Works—and the Mathematics Behind It

From spring forces and differential equations to circular-motion projections, see where equilibrium and the SHM period really come from.

Have You Ever Seen Yourself in the Crystals of the Great Crater of Paldea?

A Pokémon character faces away from the crystal—so why does the reflection show their face? Use reflection and plane-mirror imaging to unpack the physics bug.

A Story Spanning More Than 200 Years: Where the Mole and Atomic Weight Converged

From laws of proportion and atomic theory to isotopes, carbon-12, and the modern mole, trace two centuries of science behind one textbook formula.
