Hello again! Welcome to Part Two of:
Let's review the agenda:
Part One: Review of Stephen Hawking's 'A Brief History of Time' & String Theory.
Celebrating the physicists who have advanced comprehension of the universe; we quoted that, "The eventual goal of science is to provide a single theory that describes the whole universe." (Hawking). So far, the closest attempt to a unified theory is called, "String Theory," described by Physicist Michio Kaku, as a "multi-verse theory" explaining the Big Bang to either have been a "collision or fissioning of universes."
Part Two | 03.21.18: Let's address the analogies between physics and music. We review a Google Talks presentation of the book, 'The Secret Link Between Music & Universe' (2016) by physicist and jazz master, Stephon Alexander. We delve into music theory with the PBS series on Youtube, "Sound Crash Course" and "Physics of Music."
Part Three | 03.22.18: How has rock and metal, historically, adapted inspiration from discoveries in Physics? We match historical albums with Stephen Hawking quotes.
Gif | In a Nutshell
'The Secret Link / Music & The Structure of the Universe' | Stephon Alexander
YouTube & Quotes | Stephon Alexander @ Google Talks
Physicist & Artist Stephon Alexander improvises jazz and equations;
1. Early Adulthood:
"Throughout my life; music and physics were deliberately separate from each other. I used to play clubs at night and during the day do calculations for post-doc."
2. Physics and Music:
"I became friends with Brian Eno (programmer of the DX7; frequency modulated synthesis); He was freely importing ideas from science into his art into his music. I started bringing physics and music (jazz) together."
3. Book Thesis:
"I assert; after working as a theoretical physicist with quantum field theory, string theory; the name of the game is about vibration and patterns of vibration. Music, quantum mechanics and cosmology are connected."
4. Final Analysis:
"I wish someone would have told me when I was a student who was conflicted between being a musician, or being a physicist, or being a nobody - that the very birth of what we call Western science, music and astronomy and mathematics and what became physics; were all unified. It begins actually, with Pythagoras, the one who came up with the Pythagorean scale."
The Pythagorean Scale in Music, describes the universal intervals developed by Pythagoras to which orchestras tune their instruments;
Gifs & Quotes: "Sound Crash Course"
1. Introduction: "You probably receive thousands of cues about what's going on in your environment everyday, strictly from sound."
2. Thesis: "Sound is a wave which travels through a medium like air or water (or metal, or bones). Knowing that sound is a wave, is important; because we can use the physics of waves to describe the quality of sound."
thINKING ABOUT THE UNIVERSE AND MUSIC IN CONTEXT OF WAVES FEELS DIFFICULT TO PICTURE. hOW DO scientists even study what we cannot see? According to Bill Nye, with an Oscilloscope; one can measure properties of sound waves.
3. Microphones: "They use a diaphragm stretched over a sealed compartment; as sound waves pass by, they create areas of lower or higher pressure; The differences in pressure cause the diaphragm to move back and forth, which electronics translate into audio data.
4. Ears: "Your eardrums work in the same way. As sound waves pass through, they make your eardrum vibrate. Your brain then interprets those vibrations are sounds."
4. Sound Waves: "Sound is a longitudinal wave, meaning that the wave's back and forth motion happens in the same direction in which the wave travels. "
5. Wave Scale: "Humans have been describing sound by loudness and pitch. Too high in pitch is called ultrasonic, infrasonic is pitch we can't hear."
Gifs & Quotes: "Physics of Music Crash Course"
1. Introduction: "When we talk about sound waves in the context of music; there's all kinds of properties and rules to talk about."
2. String Instruments: "String instruments create sound when strings vibrate in the air."
3. Thesis: "Making music is not just an art; it's also a science."
4. Standing Waves: "String, wind & brass instruments use a special kind of wave; Standing waves; different frequencies correspond to different musical notes."
longitudinal wave, Standing waves, Frequency, Wavelength, Amplitude; understanding music involves a lot of hard work and formulas!
Conclusion | Analogies Between Physics and Math
After a brief overview of the physics behind understanding sound and music; it's apparent there is so much more to delve into: Sound Waves, Harmonies, Melodies, Music Theory & Notation, Electronics (Amps, Microphones, Synth); it's clear that music is a science!
Stay tuned tomorrow for Part 03:
