👉 Learn how to simplify expressions by multiplying its terms. When multiplying expressions, each individual term of the expression is multiplied to its like term and the exponents are evaluated using the product rule, the quotient rule...

Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary...

In this video, the teacher explains the section formula in coordinate geometry and how it can be used to find the coordinates of a point that divides a line segment in a given ratio. The teacher also introduces the midpoint formula,...

This video explains the distance formula in coordinate geometry, which is derived from Pythagoras' theorem. It demonstrates how to use the formula to find the distance between two points when given their coordinates, and also explains...

Why is there a zeroth law of thermodynamics? What use is such a simple-sounding law? And how can it be used to smash glass? Chemical engineer Valeska Ting explains in the first film from our 2016 advent calendar, all about...

Unlock the secrets of Feynman Diagrams. Part 5 in our Quantum Field Theory series.

We are surrounded by wildlife, like pigeons and squirrels, all the time. Sadly, all those animals eventually die, but why don't we see carcasses on the street? Where do they go?

Less than a tenth the size of an ant, a dust mite's whole world is contained in the dusty film under a bed or in a forgotten corner. This realm is right under our noses, but from our perspective, the tiny specks of brilliant color blend...

Today, cosmic rays are used to understand things like supernovas, but in the early 1900s, they helped us discover brand-new subatomic particles long before the first accelerators.

Can we call any economy "healthy" in the face of dwindling resources and growing inequality? What if we cut off our addiction to endless growth, and used a new compass for modern prosperity? One such compass is known as "doughnut...

Our hard-wired stress response is designed to give us the quick burst of heightened alertness and energy needed to perform our best. But stress isn't all good. When activated too long or too often, stress can damage virtually every part...
