In physics and geometry, the concept of "three dimensions" refers to a spatial framework necessary to describe the position or location of an object fully. Each dimension provides a unique axis that, together with the others, can describe any point in space. Here’s a...

Scientific Notations
Scientific notation is a way to express very large or very small numbers in a compact form. It's especially useful in fields like science, engineering, and mathematics where such numbers frequently occur. The notation is based on powers of 10. Here's the general form:...
Drive, Walk, Refuel: Find Displacement, Time & Velocity
You drive a car on a straight road at a constant speed of 70 km/h for a distance of 8.4 km, after which the car runs out of fuel. You then walk a further distance of 2 km for 30 minutes to reach the gas station. a) What is the total displacement from the beginning of your drive to your arrival at the gas station? b) What is the total time interval from the beginning of your drive to your arrival at the gas station? c) What is the average velocity from the beginning of your drive to your arrival at the gas station?
The Legacy of Puddled Iron in Contemporary Metallurgy
Puddled iron is a refined form of iron produced through a process known as puddling. It was a significant technological innovation during the early stages of the Industrial Revolution, providing a method to transform crude pig iron into a more malleable and durable material suitable for various applications. The puddling process involves melting pig iron in a reverberatory furnace and stirring it with rods, which oxidizes impurities such as carbon and silicon, resulting in a more refined iron product.
