Since the beginning of atomic testing steel has become weakly radioactive making it useless for applications sensitive to radiation such as in the manufacture of Giger Counters.

The video discusses the concept of light as a type of electromagnetic radiation and explains the different types of radiations in the electromagnetic spectrum based on their wavelength, frequency, and energy. It also highlights the...

Event: October 1921. Scientist Marie Curie, winner of two Nobel prizes, visits the White House to accept a gift of one gram of radium. Story: Marie Curie worked hard to study science and was sometimes rejected because of her gender. She...

The physics of how to cool down your cup of coffee or tea fastest. Testing with physics how to cool down your coffee or drink. And explaining heat transfer: convection, conduction, evaporative cooling. The basics of thermodynamics...

What do you think of when you hear the phrase “emitting radiation”? Do you think it’s a good thing or a bad thing? What if I told you it was vital for life on Earth?

Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive,...

Heat can be transferred from place to place by conduction, convection and radiation. Today though we'll be focusing on radiation. All objects emit and absorb thermal radiation, which is also called infrared radiation. Even we do, just a...

How did the field of quantum mechanics come about in the first place? The Rayleigh-Jeans catastrophe, also known as the ultraviolet catastrophe was a prediction by the Rayleigh-Jeans law that a blackbody would radiate infinite amounts of...

This video provides a brief yet intriguing overview of black holes, explaining their formation, characteristics, and different types. It highlights the challenges scientists face in directly observing black holes and explores the...

Are microwaves dangerous? We investigate the invisible and turn the heat, on microwaves. Help or hazard?

A comet's journey through the solar system is perilous and violent. Before it reaches Mars - at some 230 million miles away from the sun - the radiation of the sun begins to cook off the frozen water ice directly into gas. This...

At the start of the 20th century scientists had a good estimate of how old the Earth was. At least several billion years of age. This led to the tricky question as to how the Sun not only generated heat and light, but how it had done...

Now that we're done with circuits, we are going to talk about heat transfer and temperature. This video explains the laws of thermodynamics and covers the three methods of energy transfer (conduction, convection, and radiation, as well...

This video explains how thermal energy is transferred by infrared radiation and compares the ability of different material surfaces to absorb and emit this radiation. Examples of different objects and surfaces are given to illustrate...

This video is a lesson about the life and achievements of Marie Curie, a pioneering female scientist. It covers her early life in Poland, her struggles to pursue education in France, her marriage to Pierre Curie, and their joint research...

Our rocky planet Earth is wrapped up in a gaseous blanket, known as the atmosphere. It’s this atmosphere that we can thank for all the life on earth. In fact, it is the only planet in our solar system with an atmosphere that can sustain...

What have the Hulk and Spiderman got in common? They both gained their super powers because of radiation. Well, in films and comics at least. In real life, radiation has never given anyone super powers. But when used carefully radiation...

Nebulae get their name from the Latin word for cloud, but they're very different than the clouds we see on Earth. Learn what causes these space clouds and about different types of nebulae.

Check out the range of possibilities the electromagnetic spectrum gives science. This animated series of short videos acts as a video glossary to define specific scientific terms or concepts in a fun, easy to understand way. In each...

X-Rays are part of the electromagnetic spectrum and have a wavelength of about the diameter of an atom. Because of this small wavelength they are able to penetrate healthy tissue but are absorbed by denser material like bone and metal....

What happens to cells for cancerous growths to occur? Your body is made up of millions and millions of cells. In fact there are between 50 and 75 trillion cells in the body. These cells are dying and being replaced all the time. Cancer...

In this lecture video, the different types of electromagnetic waves are examined, and their uses and applications are explored. The video begins with an overview of the electromagnetic spectrum, starting with gamma rays and ending with...
