Elllipsis (Long - Space Anemone Dub)

Even Mountains Get the Blues

The Traveling Radio Show's latest episodes focus on the campuses of the CSU in California. In this episode, we visit CSU Monterey Bay. Enjoy!

The Traveling Radio Show goes to CSU Monterey Bay!

The Traveling Radio Show's latest episodes focus on the campuses of the CSU in California. In this episode, we visit CSU Sacramento. Enjoy!

The Traveling Radio Show goes to Sac State!

A "free" improvisation. I hope you enjoy.

Meditation on Black Silk

The 13th Card in the Major Arcana of the Marseilles Tarot has no name.  It generally gets a bad wrap -Death- but can also represent massive changes, revolution in one's life, the harvesting to start anew.  Hope you enjoy.

Meditation on Thirteen

Fall Up

The interlock of fragrance. mood and melody.

Black Oudh

Heart riding the thermals...this was a meditation, of sorts, a spontaneous expression of the Heart on May 4, 2024

Comme Ca (Flying Heart Mix)

This is a very different piece of music than my previous piano meditations.  Done in one take - it came on me out of the blue and represents whole new vistas for me.  Hope you enjoy!!! 

Here's what Wikipedia says about Spontaneous Emissions:

Spontaneous emission is the process in which a quantum mechanical system (such as a molecule, an atom or a subatomic particle) transits from an excited energy state to a lower energy state (e.g., its ground state) and emits a quantized amount of energy in the form of a photon. Spontaneous emission is ultimately responsible for most of the light we see all around us; it is so ubiquitous that there are many names given to what is essentially the same process. If atoms (or molecules) are excited by some means other than heating, the spontaneous emission is called luminescence. For example, fireflies are luminescent. And there are different forms of luminescence depending on how excited atoms are produced (electroluminescence, chemiluminescence etc.). If the excitation is effected by the absorption of radiation the spontaneous emission is called fluorescence. Sometimes molecules have a metastable level and continue to fluoresce long after the exciting radiation is turned off; this is called phosphorescence. Figurines that glow in the dark are phosphorescent. Lasers start via spontaneous emission, then during continuous operation work by stimulated emission.

Spontaneous emission cannot be explained by classical electromagnetic theory and is fundamentally a quantum process. According to the American Physical Society, the first person to correctly predict the phenomenon of spontaneous emission was Albert Einstein in a series of papers starting in 1916, culminating in what is now called the Einstein A Coefficient.[1][2] Einstein's quantum theory of radiation anticipated ideas later expressed in quantum electrodynamics and quantum optics by several decades.[3] Later, after the formal discovery of quantum mechanics in 1926, the rate of spontaneous emission was accurately described from first principles by Dirac in his quantum theory of radiation,[4] the precursor to the theory which he later called quantum electrodynamics.[5] Contemporary physicists, when asked to give a physical explanation for spontaneous emission, generally invoke the zero-point energy of the electromagnetic field.[6][7] In 1963, the Jaynes–Cummings model[8] was developed describing the system of a two-level atom interacting with a quantized field mode (i.e. the vacuum) within an optical cavity. It gave the nonintuitive prediction that the rate of spontaneous emission could be controlled depending on the boundary conditions of the surrounding vacuum field. These experiments gave rise to cavity quantum electrodynamics (CQED), the study of effects of mirrors and cavities on radiative corrections.

Jeff practices sound art, sound design, radio production, directing, producing, writing, and performing, and happily serves as Professor of Media Arts in the department of Broadcast & Electronic Communication Arts at San Francisco State University. Jeff has also served on the faculty of Quinnipiac University, Real Art Ways, The Media Arts Center, and the National Radio Project. Current projects include Sonic Dark Rides (sound art), The Traveling Radio Show (creative radio program), and collaborations with artists and creators working in a variety of mediums. Jacoby has been recognized for his work with an Emmy award and two Emmy nominations, two Benjamin Franklins, two Crystal Radios, four BEA Best of Competition awards, and two Ciné Golden Eagles, among other honors. His work has been heard on PBS, NPR, commercial radio, at art festivals South by Southwest, Black Maria, Festival du Cinéma de Paris, ASIFA East, and in galleries across the country. Jeff lives in San Francisco with the brilliant visual artist Sharon Steuer. For more information visit www.jeffjacoby.net.
