Mike explores some of the latest and greatest networking technologies with the Internet of Things (IoT). He describes the three common wireless technologies used to connect to IoT devices, 802.11, Zigbee, and Z-wave. Mike finishes with a...

A demonstration of a 4 x 9W light bulb smart home system prototype. Each light bulb is connected to a 5V relay module. A special input controller (instead of an Android smartphone with app) is used to turn each respective light bulb on...

This video is a lecture on energy, charge and potential difference within an electrical circuit. The presenter uses a visual aid to explain the transfer of potential energy from cells to charges within the circuit and the transfer of...

The video is a lecture presentation on the results of an experiment investigating the relationship between light intensity and the rate of photosynthesis in pondweed. The experiment involved placing pondweed in a dilute solution of...

This video explores the myths surrounding Thomas Edison and his inventions, debunking the idea of him as a lone genius and highlighting the collaborative nature of innovation. It examines the truth behind Edison's education, sleep...

The central processing unit is where the computer performs calculations. CPUs support a specific set of instructions. Internally, CPUs have multiple pipelines in order to handle multiple instructions at the same time. This clip is from...

A stream of air is used to levitate a small ball--and also a light bulb. Parts Needed 1 bendy straw 1 ping-pong ball 1 ball pit ball 1 light bulb 1 strong blower

The video is a lecture presentation on VI characteristics, where the speaker demonstrates how to investigate the relationship between the current through a light bulb and the potential difference across it. The speaker shows how to...

This video is about Sankey diagrams and how they can be used to represent energy transfers in a system or process. The video uses examples such as a car engine and a light bulb to explain how energy can be transferred and wasted in...

This video is a lecture about energy dissipation and efficiency. It begins by defining what efficiency means in energy transfer processes and how it is calculated. The video provides examples of calculating efficiencies in different...

This video is about thermal radiation and how thermal energy is transferred by infrared radiation. The video also explains how different surfaces absorb and emit infrared radiation and their effect on the transfer of thermal energy. The...

From the section: CPUs. In this section, we explore features about CPU. The central processing unit is where the computer performs calculations. CPUs support a specific set of instructions. Internally, CPUs have multiple pipelines in...

An internally frosted, large light bulb is dipped into a fish tank of water, and the total internal reflection effect produces 'other-worldly' consequences to how the bulb looks in the water. The bulb goes from white to a silvery orb....

From the section: The Internet. Here, we explore our internet options. Mike explores some of the latest and greatest networking technologies with the Internet of Things (IoT). He describes the three common wireless technologies used to...

A tutorial for a 9W light bulb smart home system. The light bulb fixture is connected to a 5V relay module as well as to the mains. An android smartphone (with app) is used to turn the light bulb on and off. ESP32S microcontrollers with...

How does physics define power? How would you write the concept of power? In some situations, why use horsepower instead of watt?<br/>
Physics Power, Part 1

This video is a lecture on electrical charge and current, explaining how current is defined as the amount of electrical charge passing a given point in a circuit per second. The presenter discusses the factors that affect the size of...

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

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...

The video is a lecture on electric power, specifically on how the rate of energy transfer is defined in an electric circuit. The speaker discusses various equations and concepts relating to power, energy transfer, current, potential...

Marketing in a Minute: Don't get discouraged when you fail; by failing you learn what does not work. In this video, Bill goes into detail about how you can benefit from failures.
