Why Did the Boeing 737 MAX Crash?
Starting in late 2018, two Boeing 737 MAX airplanes crashed, killing 346 people total. The crashes occurred just months apart and the 737 MAX was grounded as a result. Why did both airliners crash? […]

How to See Electrical Power Producing a Magnetic Field in Action
What we call electric power is voltage multiplied by current. In order to have electric power available to our plugs, we first have to generate it. And our ability to generate electrical energy really means that we convert it from another form of energy. […]

Why We Don’t Have Magnetic Charges
Magnetic fields aren’t visible to us. But if we wanted to see one, it’s as easy as pouring iron filings over a magnet and seeing how they line up from one end of the magnet to the other. […]

The Problem of Generating Electrical Energy
We use generators to get the electrical current we need. Generators are what are used to convert other forms of energy into electrical energy. […]

New Electrical Engineering Series Dives into Edison/Tesla War
Thomas Edison and Nikola Tesla’s electricity feud is legendary. While Edison championed direct electrical current, flowing just one way, Tesla worked on alternating current, which flowed in two directions. This week on Wondrium Shorts, electricity gets ugly. […]

Understanding the Natural World Through Scientific Method
The scientific method is an ongoing process that includes the following steps: observation, synthesis, hypothesis, and prediction. It is not a rigid guidebook, but rather it is an idealized path to knowledge. […]

The Science of Flight—Breaking the Sound Barrier and Beyond
During and just after World War II, the quest for ever faster fighter planes reached an apparent natural barrier—the speed of sound. Yet, on approaching this limit, aircraft became unstable and uncontrollable. In this full lecture, discover how a new approach to aircraft design solved the problem of compressibility and shock waves in this transonic region, paving the way for supersonic flight and paved the way to breaking the sound barrier.
