Your brain does its best to inform you about the world around you, but sometimes it gets tricked. Enjoy eight optical illusions to test your brain’s sensory input.

The good news is that your experimental robo-ants are a success. The bad news is that you accidentally gave them the ability to shoot deadly lasers . . . and you can't turn it off. Can you stop them from escaping their habitat before the...

Jedidah Isler dreamt of becoming an astrophysicist since she was a young girl, but the odds were against her: At that time, only 18 black women in the united States had ever earned a PhD in a physics-related discipline. In this personal...

Fifty percent of traffic accidents happen at intersections. Gary Lauder shares a brilliant and cheap idea for helping drivers move along smoothly: a new traffic sign that combines the properties of "Stop" and "Yield."

In this video, the teacher explains how to find the solutions to a system of equations by graphing them and looking for points of intersection. They demonstrate that a system of equations can have one, more than one, or no solutions,...

America is home to some of the biggest, most futuristic tech

companies in the world. But America's infrastructure — its roads, bridges, sewer
s and
tunnels — is stuck in the past, and falling apart, endangering millions of...

In this video, the teacher explains the concept of systems of equations with no solutions. They demonstrate this by graphing two equations and showing that they have parallel lines with no points of intersection. They also explain how to...

👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

In this video, we explore the concept of lateral inhibition, which is the process by which neighboring neurons in our brain pathway inhibit each other. This phenomenon enhances our visual system's ability to respond to edges of a...

In this video lesson we will learn about compound linear inequalities. We will discover that compound inequalities are two inequalities joined by an AND or an OR. You will write, graph and solve compound inequalities. You will...

The video provides an overview of two mathematical tools used to calculate probabilities: Venn diagrams and probability trees. The speaker explains the concept of sets and elements within a set, and how Venn diagrams can be used to...

Researchers at MIT have published a study outlining the basis for a potential traffic-light-free transportation design that, if developed, could allow twice as many cars to travel smoothly on the road.

👉 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...

Venn diagrams are an important tool allowing relations between sets to be visualized graphically. This chapter introduces the use of Venn diagrams to visualize intersections and unions of sets, as well as subsets and supersets.

An introduction to set theory.
