Susan Blackmore studies memes: ideas that replicate themselves from brain to brain like a virus. She makes a bold new argument: Humanity has spawned a new kind of meme, the teme, which spreads itself via technology -- and invents ways to...

Paul Andersen explains how scientists analyze and interpret data. Data can be organized in a table and displayed using a graph. Students should learn how to present and evaluate data.

One of the most important processes in science is the art of observing. This video highlights different ways observations are made, emphasizing methods by which students can observe their world. Different types of data, how data is...

👉 Learn how to evaluate the limit of a function involving rational expressions. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time. The...

Composite functions



In the introduction to functions video, we discovered what functions are, what domain and range mean and how to solve some

problems.

We saw that they could be called f(x) or
g(x) or any...

The simplest organisms can still accomplish wonders.

Unlike Earth, our Sun is a giant ball of mostly hydrogen and helium. Astronomers managed to figure that one out roughly 100 years ago. But after all this time, they still can't come to an agreement on what "mostly" means, precisely.

In this video, students will learn about the differences between bar graphs and picture graphs. They will understand that bar graphs use bars and a scale to represent data, while picture graphs use symbols and a key.

One of the most important processes in science is the art of observing. This video highlights different ways observations are made, emphasizing methods by which students can observe their world. Different types of data, how data is...

This video discusses three ways in which scientists can display and analyze data to identify patterns and relationships within the data. The first method is using bar charts to quantify and compare different categories of data, which can...

The dark side of the moon is full of mystery, and according to some, evil robots, but, in 1959 Luna 3 was able to shed some light on it for the first time.

👉 Learn about the angles on the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle...

Have you seen the videos on Youtube in which beached, deceased whales explode? How does this occur? In this video, we delve into the biological and physical reasons for this "booming" topic.

In this video series I show you how to add and subtract complex numbers. Addition and subtraction of complex numbers is very similar to addition and subtraction of polynomials where we can only combine like terms. We then want to write...
