Can Microbes See Without Eyes?

In this video, we explore the theory, use, and parameters with infrared (IR) light therapy, a sub-type of thermotherapy with a different mechanism.

Using Autodesk's free Tinkercad Circuits online web app you can build and code a virtual Arduino circuit with 3 LEDs, resistors, Arduino Uno microcontroller and a half breadboard. Block-based coding tools are also provided. This is a...

In this video, we explore the theory, use, and parameters with infrared (IR) light therapy, a sub-type of thermotherapy with a different mechanism.

Dr. Mark Matney, Space Debris Scientist and Astronomer, talks about the science and history of eclipses. He also describes the total solar eclipse that will sweep over the U.S. on August 21, 2017, and how to safely view it. HWHAP Episode 7.

In this full-lecture video, we discuss the theory, contraindications/precautions, specific uses, and techniques by which we can apply heat as a therapeutic modality along with any relevant associated parameters.

When you mix red and green, what do you get? White light is all of the colors, right? So, how do computer screens show you every wavelength of light? Or do they?

In this video, we discuss the specific uses and techniques by which we can apply heat as a therapeutic modality along with any relevant associated parameters.

New York Mayor Michael Bloomberg is pressuring the state to allow the city to install more red light cameras. Last year New York City earned $52 million from its 150 red light cameras. New York City's red-light cameras are made by...

In this video Janet Treasure discusses fear learning and how the fact that it tends to be context dependent can make recovery after hospital challenging.

A penumbral eclipse will occur over the Americas between July 4 and July 5, according to NASA.

This video teaches about color theory using high powered lasers to pop balloons. It is also an experiment in a new kind of educational video that is more interactive for the viewer.

A detailed demonstration of a NodeMCU-based IoT Smart Home Model with a Blynk app, which helps to monitor and control automated temperature and adjustable LED lighting on the model.

This video is a lecture on the colors of opaque objects and how light interacts with different surfaces to define the color of an object. It explains how white light is a combination of all visible colors and that surfaces with color...

This video explains the benefits of Blu-ray discs compared to CDs and DVDs. Blu-ray discs can store up to six times more data, thanks to the use of a blue laser beam that writes smaller. This allows for higher quality HD movies and...

In this lecture, we are going to work on a project for traffic lights.

Brandon challenges Kayne to go out after dark and spot little Penguins sneaking out of the sea to feed their babies!

NASA astronomer Lucy McFadden and UCLA graduate Carolyn Crow recently made a discovery that will help identify characteristics of extrasolar planets. By comparing the reflected red, blue, and green light from planets in our solar...

This video is a lecture on the effects of wavelength and speed on electromagnetic waves. The speaker explains what can happen to a wave at the boundary between two media, including reflection and refraction. They also discuss how...

This guided tour of the area surrounding McMurdo Station in Antarctica uses the Landsat Image Mosaic of Antarctica (LIMA). It's a great way to experience the frozen continent without any risk of frostbite.<br/>

James, our master of microscopes, recently received a package from a coral farm in Germany. We’ve explored some of the microscopic creatures and bristle worms that were living and thriving in those packages in previous videos. But today...
