If gravity is so attractive, why doesn't the earth just crash into the sun? Or the moon into the earth? The answer: Stable Orbits

In this episode we talk about dimensions and how we know that we live in 3D (or do we?).

Just because there are four dimensions doesn't mean there's a "fourth dimension"

Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what's all this nonsense of extra dimensions?

Are matter, mass, and time real?

In this shorts video we will find an unknown side length. We are given a pair of triangles and told they are similar figures. Using the definition of similar figures, similar figures have corresponding sides that are proportional, we...

The Volcano That Caused a Cataclysmic Event in El Salvador #volcano #documentary

A video entitled "Rectangular Prism Cross Sections" which shows the shape of various cross sections of the 3D figure.

What is reality? What is the standard model trying to tell us? Are we living in the 11 dimensions of string theory?



The holy grail of physics is a theory of everything. It may show the...

We just looked at note taking and sketching as two ways of documenting the crime scene. Now let's look at two more, photography and videography. What is the correct protocol for taking photos of all the evidence at the crime scene? Let's...

When protecting your garden, you can stay green with some environmentally sound solutions.

Pupil outcome: I can prepare an orthographic projection of my design. Key learning points: - Orthographic projections are used to communicate designs accurately. - Orthographic projections are to scale, show multiple views and the...

Explore how position and displacement vectors describe motion in two and three dimensions using i, j, k notation. Learn how to calculate vector differences and understand reference frames in kinematics

In this video, we use quadratics to determine the dimensions of a metal sheet that was folded up to make a box of a particular volume.

Charles Fadel, founder of the Center for Curriculum Redesign, discusses the evolving role of education in an AI-driven world. He argues that rather than focusing solely on how teachers can use AI, we should reconsider what students need...

This video contains four challenging maths puzzles with answers and explanations of how we came to that answer. These maths puzzles are great for brain training and for lesson starters. Pause the video while you work each one out.
