Semiconductors are the essential components that allow electricity to flow and regulate the flow of electrical energy in all electronic devices. They are materials that sit between conductors and insulators, enabling the controlled...

Explore the Tuolumne River from its glacial headwaters at 13,000 feet down through Tuolumne Meadows and into the Grand Canyon of the Tuolumne. Scientists and rangers describe the power this river has on the landscape and on the people...

This video provides an overview of acupuncture as an alternative treatment method. The video discusses the origins of acupuncture in traditional Chinese medicine and its belief in the flow of energy called Chi along pathways called...

This video provides a guide to the standard circuit diagram symbols that are commonly used in physics exams. The narrator explains the components that each symbol represents and how they fit into a circuit. The video covers symbols for...

Is there water on Mars? There sure is! It’s not exactly like water on Earth, but Martian H20 can tell us a lot about the planet’s distant past while potentially aiding explorers in the future. Some of the water is even trapped inside...

Main veins and tributaries of the lower extremity.

A difficult subject to talk about, but this serves as a pointer towards it.



Consciousness is a mysterious thing. But the scientific mind has struggled to understand it. Only in meditation can we unde

It explains resistance, factors affecting the resistance of a wire and resistivity or specific resistance.

In late June 2013, an exceptional binary system containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system...

Through real world footage students will learn that a change in kinetic energy of particles with heating and cooling produces expansion and contraction. Viewers will observe convection in a fluid (gas and liquid) and learn about flow in...

Our prejudices are often outdated and unecessary. Putting these lenses down can be liberating...

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 human body video lesson is all about our nose and how we smell and taste. Students will love this engaging and interactive video.This video serves as a great introduction or review video for your learners.

This video discusses the causes and treatments for heart disease, focusing on coronary heart disease and high blood pressure. It explains how fatty deposits in the arteries can lead to reduced blood flow to the heart, and the role of...

How does a battery work? Now that you think about it, you have no idea, do you? Well take a gander! Turns out it's just redox chemistry.

This nugget explains Ohm's law and its derivations for a system of resistors in series and parallel.

Here Sadhguru presents his perception of the the 5 sheaths or layers in the human being. The layers are of increasing subtlety.

This video describes the flow state, and also talks about the normal 'trying state'. Some useful pointers to get into and stay in the flow state are given.

Earlier this year Greg and I travelled to Thailand where we discovered that rubber comes from trees! Find out how natural rubber grows and learn how the locals take it from under the bark!

A discussion of resistance, and how to understand it.

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The length...
