To play the hurdy-gurdy, one needs to learn the basics, such as turning the crank, pressing the keys, and producing different pitches. The instrument can be used to play chords and create vibrato to add depth and expression to the sound.
We watch videos (also known as motion pictures) every day. Itâs hard to avoid seeing one with all the screens around us - from our phones to televisions, and even digital billboards. So, how was the first motion picture created? And prior to having screen technology, how did we even viewed them in the past? To answer that, we need to understand more about cinematography. Cinematography is the art and science of making the best out of photography and camera work to produce the right quality for the motion picture being created. From choosing how the lighting is captured through the lens, to choosing how best to display all the work. A projector is one of the earliest (read: archaic) methods of viewing...
What sounds like a cross between a violin and a bagpipe, works like a violin, held like a guitar, and plays like a keyboard. It's the almighty hurdy-gurdy! Picking up groovy hurdy-gurdy skills is definitely your gateway to learning other musical instruments in the future, such as the violin or the piano in the future. But, why these particular instruments in the future? It's because the sounds youâll learn to make on the hurdy-gurdy range from simple notes that sound like a violin, to tunes that sound like a bagpipe. The way you play the keys of the hurdy-gurdy is also undoubtedly similar to playing a keyboard or piano. How do I play the Hurdy-gurdy? How does one go about picking up...
Letâs take a closer look at the key parts of a steam locomotive and learn how a steam locomotive moves. Also, read how our mechanical wind up train, the Polaris Express, mimics an actual steam locomotive very closely.
Pendulums look innocently simple. Yet, they power some of the most jaw-dropping engineering feats we see in the modern world around us. Tall skyscrapers that remain sturdy against the strong winds? Pendulums. Earthquake resistant bridges? Pendulums. Power stations that generate energy from waves? Pendulums. Thereâs no greater way to understand this effect brought about by pendulums than by building a mechanical pendulum clock and seeing its effect come alive yourself! The engineering principles behind a mechanical pendulum clock go beyond just the pendulum alone. It is also about sustaining the released energy through the pendulumâs swing and timing, ensuring that the clock utilises this energy for as long as possible. The best case example of this is a swing in a...
