From the section: Power Supplies. Here, we check our power supply, mount the power supply and learn how to cool our PC. Power supplies come in a dizzying array of the power ratings, sizes and efficiencies. A good tech understands these...

From the section: Mass Storage Technologies. In this section, we cover topics related to Mass storage. Solid State Drives (SSDs) are quickly replacing HDDs for mass storage needs on almost all computers. SSDs are faster and more robust...

In this video, the teacher explains how to use systems of equations to solve word problems. They use the example of buying gummy bears and chocolate at a store to demonstrate the process.

This video covers renewable energy, which majors to choose in order to get into this field, and some research being done.



Renewable energy is not just one field, it can be broken up into solar, wind, geothermal,...

The central theme of this course is self-discipline. How we think about ethical problems at work and how our mind processes these problems is a huge first-step in dealing with workplace dilemmas. This process of thinking about how we...

This week we celebrate our 175th anniversary with a manifesto for renewing liberalism through a programme of radical reform. But what does this entail?

In this live-action program viewers will learn that an autoimmune disease occurs when the immune system mistakenly attacks and destroys healthy body tissue. Students will come to understand that special cells called regulatory T cells...

In 2020, Terra completed its final inclination maneuver, using some of its limited fuel supply, to maintain that crossing time. Since that final inclination maneuver, Terra has continuously drifted to an earlier...

Knowing where to look for malware lurking on your network gives you a better chance to prevent damage from it.

When we discuss zoology, we are always also talking about evolutionary biology. And with evolution, we are sometimes concerned with origins. What is the origin of animals? What is the origin of eukaryotes? What is the origin of life on...

Hospitals and other health-care stakeholders are collecting vast stores of intimate data on consumers and patients. How can that information be used to improve health and reduce costs, while protecting patient privacy?

In this video, the teacher explains how to model and solve problems with constrained solutions using systems of linear inequalities. The example used is determining the range of scores needed on a college entrance exam to get into a...

The video features Jeff Hendrickson, the executive director of the Global Human Project and the creator of Walk A Mile In My Shoes Migration Simulation, explaining the importance of teachers and educators in helping communities navigate...

In this video, I explain and demonstrate the Romberg and Sharpened Romberg test, two related balance tests that are used in the assessment of sensory organization of balance.

What's the latest, best thinking on how to build and scale the digital experience - from infrastructure, to workflow, to the team and culture that supports it?

How to solve systems of linear equations using Cramer's rule.

Charles Fadel is a global education thought leader and futurist, author and inventor, with several active affiliations; his work spans the continuum of Schools, Higher Education, and Workforce Development/Lifelong...

You had a baby! Hooray! Now it's time to stop building ramps and pulleys and it's time to start building baby stuff. You love astronomy so you decide to make a mobile of the solar system. But in order to get everything to balance out, we...

What if you had just a few seconds to sell an idea? Entrepreneurs encounter this situation every day.



Often, so do people funded by the National Science Foundation’s Small Business Innovation Research and Small...

In this video, we learn about three types of simple machines: levers, wheel and axle systems, and pulleys. The different types of levers are explained, as well as the mechanical advantages of each. We also learn about the different types...

From the section: CPUs. In this section, we explore features about CPU. CPUs are so incredibly fast today that failing to keep a steady supply of code coming into the system creates stalls that stop the CPU. To avoid stalls, all CPUs...

In this video, we explore the world of fluid power and how it's used in both pneumatic and hydraulic systems. We learn about the equations and measurements used to describe these systems, as well as the advantages and disadvantages of...

This live-action video program is about the word biodiversity. The program is designed to reinforce and support a student's comprehension and retention of the word biodiversity through use of video footage, photographs, diagrams and...
