You've probably heard of fool's gold, and it might make you think of prospectors in old timey California seeking their fortunes. But there's another kind of fool's gold called chalcopyrite, and lucky for those that want to strike...

Welcome to the thirteenth video in our chapter by chapter analysis of Kazuo Ishiguro's Never Let Me Go! In this video we'll look at the real reason Chrissie and Rodney brought our three main characters to Norfolk.

NASA and the European Space Agency are joining hands for a planetary defense mission in order to learn how to protect Earth from a possible asteroid collision. <br/>

This video is part of a series of videos that consider data analysis using R programming. It is primarily for beginners. In this video I talk about using R to visualise your data. Data visualization using R is best done using the ggplot...

R is on the rise and showing itself as a powerful option in many software development domains. At its core, R is a statistical programming language that provides impressive tools for data mining and analysis, creating high-level...

This clip is from the chapter "Maven Repositories" of the series "Apache Maven: Beginner to Guru".This section provides an explanation of Maven repositories.

In This Episode, Tyler Teaches Us About How to Analyze the Data with Charts and Graphs in Google Sheets

In this lesson, students learn how to compare rates of speed by analyzing equations that represent proportional relationships between distance and time. By finding the unit rate and dividing the distance by the time, they can determine...

👉 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...

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...

Paul Andersen explains how graphs are used to visually display data that is collected in experimentation. He describes five main types of graphs; line graph, scatter plot, bar graph, histogram and pie chart. He describes the important...

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...

The simplest organisms can still accomplish wonders.

Today we're going to start our two-part unit on data visualization. Up to this point we've discussed raw data - which are just numbers - but usually it's much more useful to represent this information with charts and graphs. There are...

In this video, the teacher explains how to display data using a histogram. They discuss the difference between a histogram and a bar graph, and demonstrate how to create a histogram by grouping data into intervals and representing the...

In this video, students learn how to create a picture graph by organizing data and creating a key, title, and labels. The video explains the importance of using the same symbol for each category in the graph and demonstrates how to...

In this lesson, students will learn how to create and graph exponential relationships by using a table of values. They will explore the concept of exponential growth and decay, and understand how to translate it into an equation.

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.

Virgin has an exciting new spaceship!

👉 Learn how to solve exponential equations in base e. An exponential equation is an equation in which a variable occurs as an exponent. e is a mathematical constant approximately equal to 2.71828. e^x is a special type of exponential...
