Don Joyce (1944 - 2015)

Don Joyce: Over the Edge at KPFA FM, Berkeley
On July 22, Don Joyce died of heart failure at the age of 71. Don was a member of the Contra-Costa-county-based experimental music group Negativland (a loose translation of "Contra Costa") and hosted Berkeley's after-midnight radio show Over the Edge on KPFA FM. Don invented the concept of "receptacle radio" in which listeners would phone in and immediately be plugged into and out of the ongoing sound collage of live guests, sound "carts" and live electronic effects at Don's discretion. The resulting mix was a radio show that was ultra-bizarre even by Berkeley standards of strangeness. Over the Edge puzzled and stimulated Bay Area listeners for 34 years.

One of Don's many on-air alter egos was Crosley Bendix, Director of Stylistic Premonitions, Universal Media Netweb, who describes here the properties of a new primary color named "squant" after its discoverer  Dr Wohat Squant.

One Thursday night in 1987, I participated in one of Don Joyce's after-hours radio romps called The Quantum Church along with Berkeley physicist Dan Ruderman and numerous live anonymous voices and sound effects channeled "out of the ether" through Don's radio "receptacles". The description for that ancient bit of experimental wireless anarchy reads: "Two quantum mechanics and a radio science show host decide to seek out the Quantum Church, a sub-atomic religious cult formed by a renegade physicist inside the Black Hole Tube of Transreality."

Don Joyce was a genius in the area of audio improvisation. I knew Don scarcely at all, but I do know this: that our world is poorer now by one exceedingly strange and beautiful life form.

Obituary here by Don's friends at Negativland.

Adios, Don Joyce

Jabir's Proof

Dr Jabir, instigator of Tantric Jihad and Urge
JABIR'S PROOF

That from a blind universe
Did arise
Billions of eyes
Like yours and mine --
Could it be any plainer than that?

That a thousand human tongues
And billions of non-human languages
Effortlessly emerged
From a universe devoid of meaning --
What could be more convincing?

That from a heartless, dog-eat-dog universe
Came so many men, women and animals
Who have loved and befriended me --
What evidence could be more persuasive?

I hold these truths to be self-evident:

This raw non-symbolic experience
of how nature feels
from the inside;

That the universe is filled
with billions of kinds 
of invisible minds;

That all sentient beings
are created
equally near to the mystery;

That deep reality
is waiting for one of us 
to ask the right question.

Six Optical Miracles

Paul Peter Ewald (1888-1985) and Carl Wilhelm Oseen (1879-1944)
Exactly 100 years ago a remarkable paper appeared in Annalen der Physik, a prestigious German physics journal in which both Max Planck and Albert Einstein published their findings. This paper, by German physicist Paul Peter Ewald explained how light behaves when it strikes a sheet of glass. Ewald, in 1915, explained, in effect, how a window works. A few year later, Swedish physicist Carl Wilhelm Oseen extended these findings to explain how light behaves when it strikes a crystal. Together the work of these two men is known as the Ewald-Oseen Extinction Theorem.

(A new proof of the extinction theorem by Mansur Mansuripur has recently been published here,)

What's so mysterious about how a window works. Isn't a window merely a sheet of glass?

A light wave traveling through a sheet of glass
When light strikes a window some of it bounces off (about 10%) and the remainder is refracted (bent) into the glass at an angle that depends on a number "n" called the refractive index which is different for different materials. If n is greater than 1, the light bends deeper into the material; if n is less than 1, the light bends towards the surface. 

In a vacuum the speed of light is equal to a constant c. But in material media, the velocity v of light is equal to: v = c/n. For visible light in glass, the refractive index is about 1.5, so light travels at about 70% of its vacuum speed: inside glass, light travels SLOW. On the other hand, for X-rays in many materials, the refractive index is less than 1, so X-ray light travels FAST -- faster than light in a vacuum.

But those "in the know" realize that not only did Einstein prohibit anything from traveling faster than light, he also showed that light always travels at the same speed no matter who's looking at it. So both the notion of fast X-ray light and slow light in glass would seem to be outlawed by relativity. However this notion of fast and slow light in material media is being taught to high school students. It's called Snell's Law (and seems to have been discovered first by Arab physicist ibn Sahl during the Islamic Golden Age.

Snell's Law (Ibn Sahl's Law) does not violate relativity, because Einstein and Snell (ibn Sahl) are talking about two different ways of measuring velocity. Einstein's prohibition refers to group velocity, how fast a packet of light can move, while Snell's Law refers to phase velocity, how fast the peaks of a wavelet can move. The difference between group and phase velocity is often illustrated by the difference between how fast a caterpillar moves (group velocity) and how fast one of his humps moves (phase velocity). It is clear from this analogy that the phase velocity can be faster or slower than whatever speed limit the caterpillar must obey. Here's a nice animation showing the difference between group and phase velocity for deep ocean waves. (In this ocean wave case, phase velocity is faster than group velocity.)

To fully appreciate the miraculousness of the Ewald-Oseen Extinction Theorem, we must first realize that glass consists of a random arrangement of electrically-excitable molecules. And that light is a traveling electromagnetic wave that will excite each of the molecules it encounters. Each excited molecule will emit a omni-directional light wave (of the same frequency as the incident light) in somewhat the same manner as an ocean buoy will emit a scattered wave when struck by an incident wave train.

Incident ocean wave striking a buoy produces scattered wave.
But light approaching a sheet of glass is not just going to strike one buoy, but approximately 10^24 buoys or about 1 million billion billion buoys (electrical excitable molecules). And these buoys (in glass) are arranged in a random fashion. What is the first thing you would imagine happening if a wave of light impinged on a medium composed of zillions of randomly arranged excitable molecules? Total chaos. That's what I would guess. The window will turn into some sort of deeply frosted glass that will randomly scatter light in every direction.

If windows are made of zillions of randomly arranged excitable molecules, then windows can not be transparent. That's what I would predict.

The first optical miracle is that windows are transparent. But the second, third and fourth miracle are even better.

Ewald proves for random media like glass (and Oseen does the same for ordered media such as crystals), that the net result of all of those zillions of little excited light waves add up to zero in every direction but three.

Only three big waves survive the fierce destructive interference between zillions of little waves. The first surviving wave travels in the same direction as the incident wave but vibrates exactly 180 degrees out of phase with the incident wave. Thus the incident wave is extinguished as it passes into the glass over a length of a few tenths of a micron (the extinction length). This exceedingly unlikely mechanism for extincting the incident wave gives the extinction theorem its odd name.

Two more waves survive the Great Destruction -- the reflected wave that seems to bounce off the glass but in reality is created by zillions of tiny molecules all radiating with the proper timing to direct a beam only in the reflected direction (and no other) much in the manner of phased-array radar antennas which do not physically move but are aimed by changing the phase relation between separate fixed transmitters. The glass molecules (like the phased-radars) are radiating in all directions but in both radar and window pane destructive interference removes light from every direction except one.

The third wave that survives the Great Cancellation is the internally transmitted wave that travels into the glass at "Snell's angle" with a "slow" phase velocity of c/n. Everywhere inside the glass the little wavelets travel at velocity c, but the net product of all their activity is an effective slow-phase wave, produced, like the reflected wave, by a kind of internal phased-antenna array consisting of zillions of glass molecules.

Here then are four optical miracles:

1. That glass is transparent despite its consisting of zillions of randomly situated electrically-excitable molecules;

2. That the excitable medium, all by itself, completely extinguishes the incident wave;

3. That the excitable medium, all by itself, synthesizes a "reflected wave" traveling in exactly the right direction and no other.

4. That the excitable medium, all by itself, synthesizes an "internal wave" traveling in exactly the right direction (Snell's Law) and no other.

These four miracles apply not just to windows but to anything made of glass, or to anything transparent for that matter, such as the lenses in telescopes, the lenses in your cameras, your eyeglasses, your contact lenses, the living lens and the clear fluid that fills your eye. The inner operation of each of these optical devices is explained by the four-fold miraculous Ewald-Oseen Extinction Theorem. (Happy Hundreth Anniversary!)

But wait. There's more. The EOET was derived in 1915 before quantum mechanics was devised. And quantum mechanics has one final miracle to add to the wonder of classical window panes and lenses.

Classical physics considered all of its waves to be "real", that is, made of something actually vibrating at every location where the wave exists. Quantum physics, on the other hand, considers its waves to be "unreal", that is, made only of sheer possibility. A light wave, for instance, represents only the possibility for a "photon" (or quantum of light) to be observed.

Quantum waves only become real in the act of observation, in a still mysterious process called by some "the collapse of the wave function".

Now imagine the situation of a single photon striking a window pane. I remind you that a window pane consists of a million billion billion electrically excitable molecules. And photons like to excite molecules. 

What do you suppose the odds are for the photon to exit the window pane without collapsing its wave function? Because there seem to be a zillion ways for that photon to lose its phase, to shed its dignity, to become entangled with the randomly arrayed electrically-excitable mess that we call "a pane of glass", I would naively guess that a pane of glass must collapse the photon wave function with 100% certainty.

But this conclusion is wrong. For exactly the same reason that the window pane is transparent (namely the Ewald-Oseen Extinction Theorem), the window pane has a lot of fun with the photon but does not actually collapse its wave function.

This is the fifth optical miracle: Window panes do not collapse the photon wave function.

Lenses do not collapse the photon wave function. Your contact lens does not collapse the photon wave function The living lens in your eye does not collapse the photon wave function. Your aqueous and vitreous humours do not collapse the photon wave function.

But inside your retina the photon wave function does somehow finally collapse into an actual event.

Which gives rise to this marvelous visual experience.

The sixth optical miracle.

The Philosopher's Bone

Nick Herbert aka Dr Jabir 'abd al-Khaliq

THE PHILOSOPHER'S BONE

(for Kelly Evans)

I'd love to own the Philosopher's Bone
As big and hard as Allah's own
With Physics, Joy and Math inside It
And me be man enough to ride It
On my board that buggers the imagination
I'd surf the Curly Crimp of Creation
I'm strong and smart; I'm a quantum knave
But where can I go to catch Her Wave?

Tom Herbert (1938 - 2015)


Tom Herbert was born on June 13, 1938 in Pittsburgh, PA and died on the same day in 2015 in Vienna, VA from complications following a stroke. He was the second-oldest of 5 children: Nick, Tom, Marilyn, Donald ("Duke") and Nancy who all grew up together in the Linden neighborhood of Columbus, OH, which was then populated mainly by immigrants from Italy, Ireland and Eastern Europe. Our Father spoke Ukrainian; Mom spoke Slovak. And both grew up in coal mining towns in Pennsylvania and Ohio, migrating North to Lorain, Ohio where some of the family found work in the steel mills along Lake Erie.

Thomas Anthony Herbert (1938 - 2015)
Tom was younger than Nick but stronger so we two were physically an even match to wrestle, box, sled, skate and explore the woods and creeks within easy reach of our neighborhood. Tom and I both went to grade school at St Augustine Catholic school (where Mom ran the cafeteria) and both completed high school at St Charles Borromeo Preparatory School. Tom was fond of animals and of water -- in our back yard he raised rabbits, chickens and ducks in addition to the obligatory dogs and cats. Not only did Tom work as a lifeguard at our local Morningside pool, but he also organized special events at the pool including water ballets. Tom also bought a kayak which he piloted on the Olentangy and Scioto rivers -- and he imagined that someday he would follow the route Huck Finn took down the Mississippi on his raft. The floor of our boy's bedroom was covered with a big linoleum map of the USA, so we could rehearse Tom's future trip down the big river using bottle caps for boats.

Tom, Nick and Duke Herbert at Betsy's Memorial Celebration
Both Tom and I obtained Bachelor's Degrees from Ohio State University, Tom in Electrical Engineering and Nick in Physics. For the next stage in his life, Nick made a move to California -- our parents gave me the family station wagon as a graduation present. Tom and I decided to use this opportunity to explore the country we had only seen printed on a floor mat. So we packed camping gear in the car and embarked on a long road trip. In those days (1960), the US was relatively uncrowded and on the few occasions we could not find a campground we just set up camp near the road and were never bothered. We explored Colorado, Utah, the Grand Canyon, Las Vegas and large parts of California together. Tom was a congenial companion and good camping buddy -- no matter what hardships we endured he would always see its humorous side. And, yes the two Ohio boys finally got to experience the mighty Mississippi (near St Louis) and to cool our feet in the Father of Waters.

Tom liked to eat and was especially fond of the Slovak food that Mom put on the table, which included stuffed peppers, stuffed cabbages (holubki), cabbage, nut and prune roll pastries. Tom enjoyed eating this kind of food so much that, unlike his brothers, he actually learned to duplicate Mom's recipes for himself. And in addition to cooking holubki, etc, Tom learned how to make Perfect Spaghetti Sauce which Mom probably learned from Leona Vanelli, her best friend. Mom used to say that Tom preferred a meal of her spaghetti and meatballs over steak.

After our road trip, Tom flew back to Ohio State where he completed his degree, met and married his first wife Dawn and began an engineering career with the Air Force at Wright-Patterson in Dayton, Ohio. Tom and Dawn produced five children: Mark, Julie, Terri, Dan and Joe. After their divorce, Tom met a female physicist who had learned how to turn silicon into gold -- Gail Walters was a brilliant computer chip designer. Their combined careers took them to Colorado, to California's Livermore Valley and finally to their present home in Virginia near Washington, DC. Tom and Gail produced one child Meghan who, when asked what she wanted to do, answered: "Anything but what my parents do."

Tom Herbert and Gail Walters

After leaving Wright-Patterson, Tom took on another government job that was so secret  he could not talk about it. Since this job often involved trips to exotic locations near the equator, I assumed it had something to do with the tracking of military spy satellites. Whatever the nature of his clandestine work, Tom always found time to explore the underwater beauties of these tropical locales in his SCUBA gear. Later Tom, Gail and Meghan would vacation in exotic places like the Caymen Islands that Tom had no doubt reconnoitered on his "business trips"

Tom Herbert in SCUBA gear
Becalmed?
Tom Herbert worked hard, played hard (and often underwater) raised two fine families, was possessed of a contagious cheerfulness. I do not know whether he believed in reincarnation, but I'd like to think that in his next life Tom might come back as a smart, sexy, good-hearted dolphin.

Tom embraces his alter ego
Bon voyage, wonderful Tom. I will miss you, little brother.

Muldoon the solid man


In the latter half of the 19th Century, Irish politicians dominated the political life of New York and Boston. The Irish musical producers Harrigan and Hart (the Rogers and Hammerstein of their day) caricatured these immigrant upstarts in the figure of Michael Muldoon, the solid man. The song has long outlived its Victorian origins and recently appeared on a Chieftains album. This version that Nick performs in Santa Cruz's Floral Park was inspired by Dublin singer Frank Harte.

 For Californians, the "Tombs" and the "Island" in the third verse, where Muldoon's constituents go "to enjoy their summer recreation and the refreshing East River air",  refer to Manhattan's infamous Houses of Detention and Blackwell's Island. Then, as now, the line between criminals and lawmakers was not easy to discern.

Thirteen Unnatural Acts

Doctor Jabir 'abd al-Khaliq

THIRTEEN UNNATURAL ACTS

Our fore-fathers and fore-mothers twisted
This natural human need to breed
Into pornography, into romance,
Into the practice of recreational sex.

Our distant ancestors perverted
This natural human need to breathe
Into speech, into singing
Into making music with wind instruments.

Our ingenious predecessors debased
This natural human need to eat
Into gluttony, into usury, into greed
Into grabbing more than we need.

And in these times we ourselves abuse
This natural human need to excrete
To poison the bees, to shit in the seas

To bequeath to our kids burning turds

Whose quantum atomic fires
Will long outlast our human deeds.

More Subatomic Particles

First 13 GeV collisions at CERN: May 20, 2015
Physicists at the Large Hadron Collider at CERN have for the fiirst time begun to collide protons at the record-breaking energy of 13 GeV. They are currently adjusting the collimators that protect parts of the accelerator from leakage of its own Gigavolt radiation. Especially vulnerable to fast-particle impact are the 1232 superconducting dipole magnets which guide both beams into a roughly circular path with a circumference of 27 kilometers. Early next month, serious experiments will begin at the highest particle energy every achieved in a physics lab. Congratulations, guys and gals!

CERN's new high-water mark reminds me of the first science fiction story I ever published -- in a collection called Semiotext(e) SF, edited by Rudy Rucker and Peter Lamborn Wilson (aka Hakim Bey). This theme of the book was the exploration of dangerous edges and includes such gems as William Gibson's "Hippy Hat Brain Parasite", "The New Boy" by William S. Burroughs, Hakim Bey's "Antarctic Autonomous Zone", "We See Things Differently" by Bruce Sterling, "Six Kinds of Darkness" by John Shirley and Rudy Rucker's "Rapture in Space".

Compared to these literary heavyweights, my contribution to Semiotext(e) may seem paltry. But I'm going to take the liberty of sharing it with you anyway:

MORE SUBATOMIC PARTICLES

Only a few weeks before the Esalen Seminar on the Nature of Reality, where top physicists and philosophers gather each year to decide what portion of the Great Secret to release to the public, private researchers at the Strongly Non-linear Accelerator Center (SNAC), Bonny Doon, California, announced the discovery of a handful of new particles that sent theorists back to their blackboards and experimentalists into their tunnels for ritual confirmation. The SNAC facility, the largest of its kind, produces the strongest weird-particle beam in the Solar System.

The first of the new particles -- christened the "Sigma" in honor of San Francisco-based theorist Saul-Paul Sirag, who predicted its non-existence -- appears to be another heavy lepton, resembling in all properties (save mass) its lighter brothers Mu and Tau. Chief SNAC scientists Drs. Kenneth Goffman and Alison Kennedy are modest about their discovery. "We see weirder things on our coffee breaks," they said, insisting that the Nobel Prize be shared with their reclusive colleague Dr. Nic Harvard, who provided the drugs necessary for the fundamental break-through.

After months of secrecy, the SNAC group's unorthodox techniques were finally revealed in Kennedy's controversial article "Quantum Tantra" published in last month's "Physical Review", the major scholarly journal of the American physics community. Kennedy's paper was immediately repudiated by established physicists for its blatant violation of normal standards of professional conduct, scientific rigor, and common decency.

Unlike the Sigma, which can be observed by any physicist with a research budget the size of America's National Debt, SNAC's other new particles are invisible to everyone not in the proper state of consciousness, the first of many examples of "state-specific physics" emerging from research projects initiated in the 1960's and only now beginning to bear fruit. In addition to their unanticipated physical properties, the new particles seem to possess mental attributes as well. Making contact is easy, but scientific study of these psychic quanta -- or "Persons", as they are called at SNAC -- is possible only by researchers with strong egos, since the experience is more akin to demonic possession than data collection.


"Expect to be changed a lot, when you mess around with Persons," warn researchers Goffman and Kennedy. "Each one is unique -- an utterly alien island of consciousness. The're around us all the time now, and the only thing they want to do is get inside your mind."


"We can't keep them in the lab. They fly right through our thickest shields. Before we could shut SNAC down, trillions of merge-hungry Persons had already escaped through the walls. They're slithering into restaurants now, into laundromats, stock exchanges and shopping malls, even into your bathtubs and bedrooms, attracted by concentrations of human emotion,"


"We're terribly sorry, folks, but everyone alive is involved in this experiment now. The era of state-specific physics has arrived."

Kiss My Bare Art

Nick Herbert: Das Gym, May 2015
KISS MY BARE ART

We drink our Muse; we smoke our Muse
We duct Her thru our gaping pores
Invent new sins to fan Her whims
We're lovely Muse's lowly whores.

We follow Muse beyond the stars
To bomb labs, muscle gyms and porno bars
Where Life beckons, there we go
Seek deeper meat than Jacques Cousteau.

We crave that rush, that punch, that flood
We love that dark orgasmic drain
Then pick ourselves up off the rug
And open up another vein.

For just one glance we drop our pants
Her prostitutes and renegades
Yet every kiss burns like the first
We're virginal as new-born babes.

Nick Meets Werner von Braun

President J. F. Kennedy and Werner von Braun: both shared a dream of landing a man on the Moon.
In 1957, I was an undergraduate at Ohio State University, a year away from a degree in Engineering Physics. I answered an ad for a summer job at Redstone Arsenal in Huntsville, Alabama. I look upon my trip to late '50s Alabama as my first visit to a foreign country.

My summer job at Redstone Arsenal was exceedingly boring, having to do mainly with documenting the mechanical parts that go into the construction of a rocket weapon. Perhaps because I possessed TOP SECRET security clearance and was almost a physicist, my bosses took mercy on me and awarded a few assignments that took me out of the blueprint trenches and into the upper atmosphere. Every week or so, I would visit an office labeled "nuclear warheads" to check if the production of these crucial components was still on schedule in line with our corporate flow chart.

Then our documentation group was assigned to publish an internal Glossary of Missile Terms for the enlightenment of the troops.  I was chosen to interview the boss of Redstone concerning, among other things, the definition of "ballistic missile". Our boss was Werner von Braun.

I elevated up to von Braun's office, was ushered in and shook his hand. He offered me a seat and I interviewed him for almost an hour about the basic physics of ballistic missiles. In 1957, von Braun was 45 years old. He appeared big and physical like a retired football player, restless and uneasy behind a desk, aching for some sort of action.

Von Braun taught me a lot about ballistic missiles. After the initial burn, a ballistic missile travels in "free fall" like a rock tossed into the air. Ideally such a rock or rocket would travel along a gravity-defined trajectory called a "parabola" (a curve that quirky author Thomas Pynchon dubbed Gravity's Rainbow). But other forces are at work on the rocket besides gravity-- primarily air resistance and fictitious forces due to the rotation of the Earth.

Inside the missile, engineers have installed an "inertial platform" constructed of gyroscopes and accelerometers. If gravity were the only player in the game, this inertial platform would feel no forces and the trajectory of the missile would perfectly track gravity's rainbow. However in the atmosphere of a rotating Earth, the missile will experience additional forces as it travels from launch site to target. A new trajectory is calculated on the ground for a model atmosphere and rotational corrections, this "more realistic" trajectory will produce an expected pattern of forces on the inertial platform.

If the inertial platform feels only these expected forces, it does nothing, but if new forces are encountered different from those predicted for the path stored in its computer memory, the missile fires small attitude-control rockets to bring the rocket back into its calculated course.

The flight of a ballistic missile then is not truly ballistic. Its theoretical trajectory is calculated with the best corrections available -- producing a non-parabolic arc between launch and target site. En route to the target, the inertial platform measures the deviation between this theoretical path and the path the missile is actually following and applies appropriate rocket thrust to bring the course in line with what theory says it ought to be.

After a few more questions about other topics, I thanked the boss for giving me so much of his time, shook his hand a second time and went back to my pals in the trenches. I returned to school in Ohio before the missile glossary was completed and a few months later, the Russians sent up Sputnik, whose beep-beep-beep from space forever changed the world.

Alabama in 1957 was indeed for me a foreign country, with its incomprehensible deep South dialect, its peculiar patterns of racial segregation, its colorful Bible-belt fundamental preachers on the stairs of the Huntsville Court House, born-again Baptist tent revivals in the countryside and the ever-present feeling in the air (and in the public statues of Confederate heroes) that for many residents of Alabama the War Between the States was still current news. I was often referred to as a "Yankee"

And only much later, back home in Columbus, did I realize that in that casual interview with Werner von Braun, Nick Herbert's skin had come in contact with real psychic power --  Nick's hand one mere handshake away from the hand of officially designated Grand Satan Unsurpassed.
