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? […]

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. […]
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. […]
We use generators to get the electrical current we need. Generators are what are used to convert other forms of energy into electrical energy. […]
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. […]
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 subject of genetics is huge, it studies the evolution of humans through parental traits and their relation with various species. Does the study also help in knowing how crossbreeding can result in a variety of different plants? […]
Genetically modified organisms are useful for farmers as plants can be modified to keep insects away and increase the yield. Being so beneficial for foods, why are most people concerned about GMOs used in animals and plants? […]
There are some dominant genes which can pass on to one’s offspring. Also, the human trait of eye color has a single gene governing it. Which color eyes are dominant and which recessive? […]
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.
