This video explains the concept of selection bias and how it can lead to false conclusions. Through examples like the story of Abraham Wald and the Simpson Paradox, it demonstrates the importance of understanding data and selecting...

This video explores five fun facts about WW2.

A Vapor Cone is a cloud around the rear of a very fast jet plane, in the shape of a cone, formed by quickly falling pressure, falling temperature, and rising relative humidity. It does not require a plane to break the sound barrier and...

When the elimination method is used to solve a system of linear equations, viewing the geometrical changes that happen to the system during this process can give insight into the mechanisms which underlie the logic behind the algebraic...

This clip explores the historical history, and some important cultural features of the Great Plains Region.

When Gauss-Jordan elimination transforms a matrix representing an inconsistent system of linear equations to reduced row-echelon form, a matrix row containing all zero coefficient entries and a non-zero constant entry is produced,...

When the graph of the solutions of a system of linear equations in three variables is a line in Cartesian space, the solutions can be described either by a group of three parametric equations, or a parametric ordered-triple. This lecture...

In this video, the teacher explains how to estimate the measure of angles using visual clues and benchmark angles. They give examples of estimating the angle of a plane's takeoff, the opening angle of a door, and the angle formed by bike...

It's common to think that the UK doesn't actually manufacture anything these days, and assume that the UK has left manufacturing in the past. However, the stats show that's not true. Manufacturing is growing in the UK and there are some...

Despite early warnings of a catastrophic fire season, authorities are still scrambling to get extra water bombing aircraft to Australia. Four jet water bombers called up by the Prime Minister are stuck overseas, unable to fly because of...

In this lesson, students will learn how positive and negative numbers are used to measure elevation above and below sea level. They will understand that sea level represents 0 elevation, and that both positive and negative elevations...

This video covers a summary of the book "How not to be wrong, the power of mathematical thinking". Most of the math we learn in high school and beyond is not used ever again (unless you go into math, science, or engineering). ...

Although Gauss-Jordan Elimination is typically thought of as a purely algebraic process, when viewed geometrically, this process is beautiful and amazing, providing insights into the underlying mechanisms of the matrix transformations...

When solving a system of linear equations with a single solution, we get a unique value for each variable. But how do we recognize when a system of equations has infinitely many solutions or no solutions?

👉 Learn how to label points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A point is...

This video is a quick look at the topics and should be used with my other what's on paper 1 video. I go through some of the key areas that I think will come up on the gcse pe exam this year

New inventions and improvements are almost always made by teams – innovation is a team sport! This video will explore how STEAM teams work collaboratively to solve problems.

Once a system of linear equations has been converted to augmented matrix form, that matrix can then be transformed using elementary row operations into a matrix which represents a simpler system of equations with the same solutions as...

Here is volume 8 of the planet pe 5 a day gcse pe revision questions. As we move towards the exam in a few weeks time I will be posting 5 questions each day to help test your revision. Place your answers in the comments section and...

The U.S. Air Force IS investigating the circumstances surrounding human remains found in the wheel well of C-17 cargo plane call sign REACH885, which flew out of Afghanistan’s Hamid Karzai International Airport on Tuesday, August 17.

Join us on an adventure as we explore the captivating city of Saigon, also known as Ho Chi Minh City, in Vietnam. In this video, we delve into the rich history and cultural significance of Saigon, from its French colonial architecture to...

This lecture examines an example of Gauss-Jordan elimination on a dependent system from Algebra chapter 58, and follows how the planes are geometrically transformed step by step, from a system of three planes, representing three...

👉 Learn essential definitions of points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A...

This video tells the story of Garuda Airlines navigating through financial crises, mismanagement, tragedies, and debt restructuring in the early 2000s. Despite facing immense challenges, new leadership and strategic decisions helped the...
