I bet you’ve sat on an office chair at least in one point in your life. Those cool chairs are super comfortable with thick cushions, and oh my, you can move around with the wheels and spin around the chair! When I was a kid, I used to love spinning…

Your elementary school teacher may have taught you that there are three states of matter: Solids, liquids and gases. The fourth state of matter is plasma, which occur at extremely hot temperatures. Recently, scientists have discovered the fifth sate of matter — the Bose-Einstein condensate. A Bose–Einstein condensate (BEC) is…

Open sesame! A while ago, the Internet has been torn up debating whether there are more doors or wheels. However, why are doorknobs placed on the side, but not the hinge? This is related to torque, which I will be explaining in this article. Linear and Angular Equivalents You may have came across Newton’s…

The third law of thermodynamics states, “the entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 K)”. But what does this statement mean? In this article, I will discuss the meaning behind this law and present it in a clear…

For a long time, scientists have yearned to create the ideal engine to maximize power output and optimize efficiency. But many of them failed. This poses a theoretical question — does an ideal engine really exist, or is it a distant dream scientists have yet to achieve? An engine or…

“Give me a place to stand,” contended Archimedes, “and I will move the world.” Ignorant critics did not understand disdained Archimedes’ idea. They probably did not understand the working principles of the levers. In this article, I will explain Archimedes’ quote by using examples from our daily life to demonstrate…

Vroom, a racecar speeds by, leaving behind a trail of dust. Have you wondered how can racecars run so fast? To understand how racecars work, one must understand the fundamentals of aerodynamics — the study of the motion of an solid object, such as an airplane, through air. Air resistance…

Ring! The alarm clock incessantly chimes to wake its sleeper. You may hate your alarm clock for disturbing your sweet dreams — or you may thank your alarm clock for waking you. But how does physics govern alarm clocks? The Basics About Waves Before we dive into the physics behind alarm clocks, let’s understand…

You probably have used a ballpoint pen at some point in your life. Or perhaps you use it every day. Well, did you know that this simple writing tool beholds the phenomenal laws of physics? Have you wondered what makes the ball in the ball point pen rotate and allow…
