 Pianos Make Music Accessible Like Computers Make Math Acc...

Though it has become a naturalized part of music-making since the first one was built in 1710, the pianoforte (its name means "soft-loud") was a technical marvel for its time, a machine that changed music in ways that are hard to imagine. Computer pioneer Alan Kay once observed that any technological advance is "technology only for people who are born before it was invented,' and in the case of the piano, this applies to no one alive today. Seymour Papert, the MIT researcher, concluded, "That...

 The Machine Euthanizes the Atheletic

"Well, the Book"s wrong, for I have been out on my feet." For Kuno was possessed of a certain physical strength. By these days it was a demerit to be muscular. Each infant was examined at birth, and all who promised undue strength were destroyed. Humanitarians may protest, but it would have been no true kindness to let an athlete live; he would never have been happy in that state of life to which the Machine had called him; he would have yearned for trees to climb, rivers to bathe in, meado...

 The Mind on Music

For some reason that no one really understands, there is a psychological effect upon human listeners in regards to the musical scale. The tonic pitch, or tonal center is not only the mathematical center of the scale, but is the psychological center as well. Human perception of the tonic pitch in relation to the other notes of the scale gives each note of the scale, including the tonic pitch, a distinct "personality" or identity. If we were to label each note of the major scale with a number, ...

 China to Rate Online Behaviour in Social Credit System

Chinese internet firms are definitely interested, as Ant Financial, a subsidiary of ecommercegiant Alibaba, recently showed. To its popular app Alipay it added a new service which rated a person's credit worthiness on a scale of 350 to 950 points. This score is not only determined by one's lending behavior, but also by hobbies and friends. If friends have a poor lending reputation, this reflects badly on the person, just as prolonged playing of video games. Buying diapers indicates responsibi...

 The Many Ways of Representing Sounds in English Spelling

English spelling, owing to the conditions that gov- ernd the growth of the English language, now presents many anomalies. The same letter, or combination of letters, often represents many different sounds; while the same sound is often represented by many different letters, or combinations of letters. The combination ough, for example, represents at least 9 different sounds in the words cough, rough, though, through, plough, hough, thorough, thought, hiccough; and the sound of e in ...

 The Sensation of Pressure

We feel pressure on our skin, when we place our hand over the outlet of a bicycle pump, for example, as a kind of springy push. Actually, pressure is the summed bombardments of thousands of molecules of air, whizzing about in random directions (as opposed to a wind, where the molecules predominantly flow in one particular direction). If you hold your palm up to a high wind you feel the equivalent of pressure - bombardment of molecules. The molecules in a confined space, say, the interior of a...

 Characteristics of a Game

When you strip away the genre differences and the technological complexities, all games share four defining traits: a goal, rules, a feedback system, and voluntary participation. The goal is the specific outcome that players will work to achieve. It focuses their attention and continually orients their participation throughout the game. The goal provides players with a sense of purpose. The rules place limitations on how players can achieve the goal. By removing or limiting the obvious ways...

 The Unknowable

This girl was perhaps not born of a mother. But blossomed in a peach tree: Her love fades Quicker than peach-flowers. Although I know her soft body I cannot sound out her heart; Yet we have but to make a few lines on a chart And the distance of the farthest stars In the sky can be measured.

 Fourier Transformations

So what was Fourier’s discovery, and why is it useful? Imagine playing a note on a piano. When you press the piano key, a hammer strikes a string that vibrates to and fro at a certain fixed rate (440 times a second for the A note). As the string vibrates, the air molecules around it bounce to and fro, creating a wave of jiggling air molecules that we call sound. If you could watch the air carry out this periodic dance, you’d discover a smooth, undulating, endlessly repeating curve that’...

 The 12-Note Octave is Too Good to be True

[Playing notes on a piano] One... Two... Three... Four... Five... Six... Seven... Eight... Nine... Ten... Eleven... Twelve... 12 different pitches, and then back to where we began. Incredible! Fantastic! The mystical number 12. There are 12 hours in the A.M. and 12 hours in the P.M. The new day begins at 12 midnight. There are 12 months in a year. Both the Western and Chinese Zodiac have 12 signs. Further, the Chinese use a 12-year cycle for reckoning time. There are 12 eggs in a dozen. 12 d...

The number 12 seems so perfect, but a 12-note scale made of 3/2 ratios brings the circle around to a point a little sharper than the the next octave.
