Marc Estrin : Happy Birthday, Albert Einstein

Albert Einstein and Marie Curie.

HAPPY BIRTHDAY, ALBERT

(Albert Einstein was born on March 14th, 1879.)

Blanchot : "La réponse est le malheur de la question." (The answer is the misfortune of the question.)

ALBERT EINSTEIN SAID
Sometimes I ask myself how it came about that I happened to be the one to discover the theory of relativity. The reason is, I think, that the normal adult never stops to think about space and time. Whatever thinking he or she did about these things will already have been done as a small child. It, on the other hand, was so slow to develop that I only began thinking about space and time when I was already grown up. Naturally I then went more deeply into the problem than an ordinary child.
THE ANSWER IS THE MISFORTUNE OF THE QUESTION

There exists a remarkable photograph of Einstein and Marie Curie standing together on a naked, blasted heath, both dressed in black -- he in a cape, she in a hooded cloak. They look like allegorical figures from an early Bergman film -- set eternally there for us to ponder their meaning, their relationship to one another, their relationship to us.

I'd been carrying that mysterious image around for a long time when I came upon a poem by Adrienne Rich which explained it to me:
Today I was reading about Marie Curie

She must have known she suffered from radiation sickness
her body bombarded for years by the element
she had purified.
It seems she denied to the end
the source of the cataracts on her eyes
the cracked and suppurating skin of her
finger ends
till she could no longer hold a test tube or a
pencil

She died a famous woman denying her wounds
denying her wounds came from the same source
as her power.
Einstein, too, suffered from radiation sickness. Einstein, too, denied. Two kinds of radiation sickness, actually. Sickness over his unintended contribution -- in theory and in practice -- to the deaths of so many and the poisoning of the planet. And sickness about from-radiation-born physics, a disease within the whole swing of science which left him behind, an oddball, a hermit, a naysaying party pooper, a pathetic, has-been, once-important old man.

His wounds came from the same source as his power. The power to imagine an entirely other view of the world, of the universe, the view of someone who rides on a light beam. The power of the light-beam-rider to see the light also enabled him to envision a world without war, a world beyond nations, beyond power, greed and corruption. One can't see these visions without being seriously wounded. One can't be wounded without denying.

"God does not play at dice," he said. Events in the world must have a cause, in spite of what the quantum mechanics were saying. At its deepest level the universe must be orderly, not random. If he could only find this statement which would describe it. "Forget it," said the mechanics.

He wouldn't forget it. His eyes were glued on the universe and the possibility of penetrating to the ultimate core where all secrets would be resolved and understood as the emanation of a single law. This law, the unified field theory, would be for him the name of God. He could never name the Name. His wounds came from the same source as his power. He could never name the Name

ALBERT EINSTEIN SAID
Everyone who is seriously involved in the pursuit of science becomes convinced that a spirit is manifested in the laws of the Universe -- a spirit vastly superior to that of humanity, and one in the face of which we, with our modest powers, must feel humble. In this way the pursuit of science leads to a religious feeling of a special sort, which is quite different from the religiosity of someone more naïve.
THE ANSWER IS THE MISFORTUNE OF THE QUESTION

MOSES AND ARON

He could never name the name of God. It is a remarkable coincidence that just at the time Einstein was leaving the physics community, beginning his retreat into the desert of his solitary vision quest, another German seeker was articulating something very similar. Let's switch our eyes over to the power and wounds of Arnold Schoenberg, the great revolutionary who broke open a millennium of Western tradition to lead music into uncharted territory. Between 1923 in 1928 he worked on his largest, most ambitious and shattering work, his opera, Moses and Aron. This piece is a radical and comprehensive act of the imagination, an attempted human song in the face of the unspeakable immensity of God.

At the opening of the first act, Moses hears the wordless voice of God, and understands that it is einziger, ewiger, everywhere, invisible and inconceivable. Standing in relation to such a God, he cannot sing, he is almost dumb, he can express himself only in a halting, halfway manner, using a vocal technique of Schoenberg's called Sprechstimme -- half singing, half speaking, limited, frustrated, fallen. The voice from the burning Bush instructs him to prophesy the name of the eternal God. But he resists. He is too simple, he cannot speak, he cannot express the infinite.

No prob. Aron, his brother, sizes up the situation, and is ready for the job. He has a beautiful tenor voice, sight-sings well, and although describing the infinite God is a difficult task, he'll give it a shot. Granted, it may be only an approximation, but it's close enough for church work, and besides, the people need an image to hang onto, or they just won't buy the whole business.

The opera concerns the conflict between Moses and Aron over trying to enclose the boundless in a finite image. Like Einstein.

ALBERT EINSTEIN SAID
I do not believe in a personal God. If something is in me which can be called religious, it is the unbounded admiration for the structure of the world so far as science can reveal it. My religiosity consists in a humble admiration of the infinitely superior spirit that reveals itself in the little that we, with our weak and transitory understanding, can comprehend of reality.
THE ANSWER IS THE MISFORTUNE OF THE QUESTION

THE RETREAT FROM THE WORD

A nine-year-old asked me the other day "What did Einstein do?" I found it hard to describe. If he had invented the steam engine or discovered penicillin, or the charge on the electron, I could've explained more easily. But just try telling a child what Einstein did -- it ain't easy. And that is in large part because what he did is not in English. It's not in German either. As his futile search dragged on, it was conducted more and more in the language of mathematical symbols, unrepresented by the tongue.

This was new, but not, perhaps, inappropriate. New because until relatively recently, our Judeo-Christian culture bore witness to the belief that all truth and realness -- with the exception of a small, clear margin at the very top -- could be housed inside the walls of spoken language. Until the 17th century, the predominant bias and content of the natural sciences were descriptive. But with the invention of analytic geometry and the theory of algebraic functions, with the development of calculus, mathematics transcended being an instrument to characterize certain aspects of nature, and became its own independent language, one of progressive untranslated ability. Mathematical forms and meanings have receded from spoken language at an ever accelerating pace. For no dictionaries to relate the vocabulary and grammar of contemporary higher mathematics to ordinary speech. One cannot even paraphrase.

This was the world in which Einstein ended. No more railroad cars and flashing lights of special relativity. Gone were the elevators of general relativity. Just pages and pages of reiterative tensor equations. The small, queer margin at the top. No song; beyond speech; never expressible even in its own terms. Einstein. Moses. The Unspeakable, Unreachable Absolute Idea of God.

ALBERT EINSTEIN SAID
The religious feeling engendered by experiencing the logical comprehensibility of profound interrelations is a somewhat different sort from the feeling that one usually calls religious. It is more a feeling of awe at this scheme that is manifested in the material universe. It does not lead us to fashion a godlike being in our own image -- a personage who makes demands of us and to take some interest in us as individuals. There is in this neither will nor goal, but only sheer being.
THE ANSWER IS THE MISFORTUNE OF THE QUESTION

THE TRIAL OF ALBERT EINSTEIN

PROSECUTOR
Is it not true that your discoveries of mass and energy equivalence led directly to the production of atomic weapons?

EINSTEIN
(Shakes his head vehemently)

PROSECUTOR
Is it not true that you wrote a series of letters to President Roosevelt recommending that the United States develop an atomic bomb?

EINSTEIN
(Thinks, then shakes his head decisively)

GEORGE GAMOW
When Einstein accepted a consulting ship with the Bureau of Ordinance he said he would be unable to travel to Washington regularly, and that someone from the Division of High Explosives would have to come up to meet him at Princeton. I was selected to carry out the job. And so, on every other Friday, I took a morning train to Princeton, carrying a briefcase packed with secret Navy projects. Einstein would meet me in his study at home, and we would go through all the proposals one by one. He approved practically all of them, saying, "Oh, yes, very interesting, very, very ingenious," and the next day the admiral in charge was quite happy with Einstein's comments.

EINSTEIN (screams out)
I have never worked in the field of applied science, let alone for the military! I condemn the military mentality of our time just as you do! I have been a pacifist all my life, and I regard Gandhi as the only truly great political figure of our time!
(Pause, quietly...)
I just served as a mailbox. They brought me a letter and all I had to do was sign...

AUDIENCE APPLAUSE FOR FAMOUS SPEAKER EINSTEIN

EINSTEIN
Our time is distinguished by wonderful achievements in the fields of scientific understanding and technical application. But let us not forget that knowledge and skills alone cannot lead humanity to a happy and dignified life. What humanity owes to Buddha, Moses and Jesus ranks for me higher than all the achievements of the inquiring and constructive mind. What these blessed men have given us we must guard and try to keep alive with all our strength if humanity is not to lose its dignity, the security of its existence, and the joy in living.

APPLAUSE

EINSTEIN
The unleashed power of the atom has changed everything save our ways of thinking, and thus we drift toward unparalleled catastrophe. A new way of thinking is essential if humanity is to survive and move toward higher levels.

HUGE APPLAUSE

EINSTEIN
The big political doings of our time are so disheartening that one feels quite alone. It is as if people had lost the passion for justice and dignity and no longer treasured what better generations have won by extraordinary sacrifice. The foundation of all human value is morality. To have recognized this clearly in primitive times is the unique greatness of our Moses. In contrast, look at the people today...

POLITE APPLAUSE

EINSTEIN
(Yelling)
It is easier to change the nature of plutonium than people's evil spirit!
(He looks at the clappers, who do not respond)
People grow cold faster than the planet they inhabit.
(He looks for God)
Mine eyes fail with looking upward.
(Pause)
Three great powers rule the world: stupidity, fear and greed.

SILENCE
THE ANSWER IS THE MISFORTUNE OF THE QUESTION

ALBERT EINSTEIN SAID
People like you and me, though mortal like everyone else, do not grow old no matter how long we live. What I mean is that we never cease to stand like curious children before the great Mystery into which we are born.
THE JEWISH QUEST FOR THE ABSOLUTE

Aron puts forth a comprehensible image so that Israel may live and not fall into despair. Moses loves an idea, an absolute vision, relentless in its purity. He would make of Israel the hollow, tormented vessel of an inconceivable presence.

Here, in George Steiner's imagination (in The Portage to San Cristóbal of A.H.), is Hitler's self-defense after he was captured as an old man in the Brazilian jungle:
"There had to be a solution, a FINAL solution. For what is the Jew if he is not a long cancer of unrest? Gentlemen I beg your attention. Was there ever a crueler invention, a contrivance more calculated to harrow human existence, than that of a non-impotent, all seeing, yet invisible, impalpable, inconceivable God?... the Jew emptied the world by setting his God apart. No image. No concrete embodiment. No imagining even. A blank emptier than the desert. Yet with a terrible nearness. Spying on our every misdeed, searching out the heart of our heart for motive... the Jew mocks those who have pictures of their God. HIS God is purer than any other. And because His inconceivable, unimaginable presence and develops us, we must obey every jot and tittle of the Law. We must bottle up our rages in desires, chastise the flesh and walk bent in the rain. You call me a tyrant, and enslaver. What tyranny, what enslavement has been more oppressive, has branded the skin and soul of man more deeply than the sick fantasies of the Jew? You are not God killers, but GOD makers. And that is infinitely worse. The Jew invented conscience and left humanity guilty serfs.

"But that was only the first piece of blackmail. There was worse to come. The white-faced Nazarene. Gentleman, I find it difficult to contain myself. But the facts speak for themselves. What did that epileptic rabbi ask of us? That we renounce the world, that we leave mother and father behind, that we offer the other cheek when slapped, that we render good for evil, that we love our neighbor as ourselves, no, far better, for self-love is an evil thing to be overcome. Oh grand castration! Note the cunning of it. Demand of human beings more than they can give, demand that they give up their stained, selfish humanity in the name of a higher ideal, and you will make of them cripples, hypocrites, mendicants for salvation. The Nazarene said that his kingdom, his purities were not of this world. Lies, honeyed lies. It was here on earth that he founded his slave-church. It was men and women, creatures of flesh, he abandoned to the blackmail of hell, of eternal punishment. What were our camps compared to THAT? What can be crueler than the Jew's addiction to the ideal?

"First the invisible but all seeing, the unattainable but all demanding God of Sinai. Second the terrible sweetness of Christ. Had the Jew not done enough to sicken man? No, gentlemen, there is a third act to our story.

"'Sacrifice yourself for the good of your fellow man. Relinquish your possessions so that there may be equality for all. So that justice may be achieved on earth. So that history may be fulfilled and society be purged of all imperfection.' Do you recognize that sermon, gentlemen? Rabbi Marx. Was there ever a greater promise? 'The classless society, to each according to his needs, brotherhood for all humanity, the earth made a garden again, a rational Eden.' In the name of which promise tyranny, torture, war, extermination were a necessity, a historical necessity! It is no accident that Marx and his minions were Jews, that the congregations of Bolshevism -- Trotsky, Rosa Luxembourg, the whole fanatic, murderous pack -- were of Israel. Look at them: prophets, martyrs, smashers of images drunk with the terror of the absolute. It was only a step, gentleman, a small inevitable step, from Sinai to Nazareth, from Nazareth to the covenant of Marxism. The Jew had grown impatient. Let the kingdom of justice come here and now, next Monday morning. Let us have a secular messiah instead. But with a long beard and his bowels full of vengeance.

"You are not humanity's conscience, Jew. You are only its bad conscience. And we shall vomit you so we may live and have peace."
The Nazis set a price of 50,000 marks on Albert Einstein's head.

ALBERT EINSTEIN SAID
You believe in a God who plays dice, and I in complete law and order in a world which objectively exists, and which I, in a wildly speculative way, am trying to capture. I hope that someone will discover a more realistic way, or rather a more tangible basis than it has been my lot to find.
THE ANSWER IS THE MISFORTUNE OF THE QUESTION

The physicists walked away from Einstein to follow Schrodinger's cat. The old man was left alone on his deathbed, pad and pencil in hand.

ALBERT EINSTEIN SAID

God does not play at dice.

Infinite Universes : Death Does Not Exist

Does death exist?
New theory says 'No'
One of the surest axioms of science is that energy never dies; it can neither be created nor destroyed. But does this energy transcend from one world to the other?
By Dr. Robert Lanza / December 9, 2009

Many of us fear death. We believe in death because we have been told we will die. We associate ourselves with the body, and we know that bodies die. But a new scientific theory suggests that death is not the terminal event we think.

One well-known aspect of quantum physics is that certain observations cannot be predicted absolutely. Instead, there is a range of possible observations each with a different probability. One mainstream explanation, the "many-worlds" interpretation, states that each of these possible observations corresponds to a different universe (the 'multiverse'). A new scientific theory -- called biocentrism -- refines these ideas.

There are an infinite number of universes, and everything that could possibly happen occurs in some universe. Death does not exist in any real sense in these scenarios. All possible universes exist simultaneously, regardless of what happens in any of them. Although individual bodies are destined to self-destruct, the alive feeling -- the "Who am I?" -- is just a 20-watt fountain of energy operating in the brain. But this energy doesn't go away at death. One of the surest axioms of science is that energy never dies; it can neither be created nor destroyed. But does this energy transcend from one world to the other?

Consider an experiment that was recently published in the journal Science showing that scientists could retroactively change something that had happened in the past. Particles had to decide how to behave when they hit a beam splitter. Later on, the experimenter could turn a second switch on or off. It turns out that what the observer decided at that point, determined what the particle did in the past.

Regardless of the choice you, the observer, make, it is you who will experience the outcomes that will result. The linkages between these various histories and universes transcend our ordinary classical ideas of space and time. Think of the 20-watts of energy as simply holo-projecting either this or that result onto a screen. Whether you turn the second beam splitter on or off, it's still the same battery or agent responsible for the projection.

According to Biocentrism, space and time are not the hard objects we think. Wave your hand through the air -- if you take everything away, what's left? Nothing. The same thing applies for time. You can't see anything through the bone that surrounds your brain. Everything you see and experience right now is a whirl of information occurring in your mind. Space and time are simply the tools for putting everything together.

Death does not exist in a timeless, spaceless world. In the end, even Einstein admitted, "Now Besso" (an old friend) "has departed from this strange world a little ahead of me. That means nothing. People like us... know that the distinction between past, present, and future is only a stubbornly persistent illusion." Immortality doesn't mean a perpetual existence in time without end, but rather resides outside of time altogether.

This was clear with the death of my sister Christine. After viewing her body at the hospital, I went out to speak with family members. Christine's husband -- Ed -- started to sob uncontrollably. For a few moments I felt like I was transcending the provincialism of time. I thought about the 20-watts of energy, and about experiments that show a single particle can pass through two holes at the same time. I could not dismiss the conclusion: Christine was both alive and dead, outside of time.

Christine had had a hard life. She had finally found a man that she loved very much. My younger sister couldn't make it to her wedding because she had a card game that had been scheduled for several weeks. My mother also couldn't make the wedding due to an important engagement she had at the Elks Club. The wedding was one of the most important days in Christine's life. Since no one else from our side of the family showed, Christine asked me to walk her down the aisle to give her away.

Soon after the wedding, Christine and Ed were driving to the dream house they had just bought when their car hit a patch of black ice. She was thrown from the car and landed in a banking of snow.

"Ed," she said "I can't feel my leg."

She never knew that her liver had been ripped in half and blood was rushing into her peritoneum.

After the death of his son, Emerson wrote "Our life is not so much threatened as our perception. I grieve that grief can teach me nothing, nor carry me one step into real nature."

Whether it's flipping the switch for the Science experiment, or turning the driving wheel ever so slightly this way or that way on black-ice, it's the 20-watts of energy that will experience the result. In some cases the car will swerve off the road, but in other cases the car will continue on its way to my sister's dream house.

Christine had recently lost 100 pounds, and Ed had bought her a surprise pair of diamond earrings. It's going to be hard to wait, but I know Christine is going to look fabulous in them the next time I see her.

[Robert Lanza, MD, is considered one of the leading scientists in the world, especially for his pioneering work in stem cell research. He is Adjunct Professor at the Institute for Regenerative Medicine, Wake Forest University School of Medicine. He is the author of Biocentrism: How Life and Consciousness Are the Keys to Understanding the True Nature of the Universe , a book that lays out his theory of everything.]

By Bending Light, Researchers Appear Closer to Creating Invisibility Cloak


The fantasy-like technology offers practical uses, like making computer chips even smaller
By John Johnson, Jr. / August 12, 2008

Long the stuff of fantasy, practical invisibility shields have been brought a step closer to reality by researchers who say they have engineered materials that can hide an object by bending ordinary light like balloon animals at a circus.

The researchers, led by Xiang Zhang of the Nanoscale Science and Engineering Center at the University of California, Berkeley, have created two composite materials that possess negative refraction indexes, meaning they bend light opposite to the way most natural substances do. If water exhibited negative refraction, fish swimming in a pool would appear to be in the air above the water.

"This is an important step toward creating a cloak," Zhang said Monday.

But he insisted the work was not aimed at shielding Federation starships from Klingon battle cruisers. A more practical application, he said, would be to create a so-called "super lens" that could image infinitesimally small objects, enabling the manufacture of still tinier computer chips.

Materials scientists previously have found two-dimensional materials that cause negative refraction, making an object seem to disappear. But the light-bending properties of these materials were unreliable, the science team said.

The Berkeley researchers, whose work appears this week in the journals Science and Nature, created two different, three-dimensional materials that exhibit negative refraction.

The first method involved stacking alternating layers of silver and magnesium fluoride, a transparent compound used in lenses and windows. Then, tiny fishnet patterns — with holes 860 nanometers apart, or less than one-hundredth the diameter of a human hair — were cut into the layers.

Jason Valentine, a UC Berkeley graduate student, said the layers of fishnet work together to bend the light in an unnatural direction. With further development, the material might eventually be able to bend light entirely around an object, channeling it like water flowing around a rock. With no light reflected back at a viewer, the object would not be visible.

The silver-magnesium fluoride material worked only on light frequencies in the infrared range, beyond the visible spectrum. But with a second technique, researchers succeeded in bending light in the red portion of the visible light spectrum.

The technique involved placing small silver nano-wires inside porous aluminum oxide to accomplish a similar light-channeling ability.

Among the advantages of these new materials is that less light is lost than with the previous two-dimensional materials.

Jie Yao, a graduate student in applied science and technology, said several obstacles remained before the materials could be put into mass production. The material is expensive to produce, and researchers need to demonstrate negative refraction at all wavelengths of visible light, not just red.

They also must overcome the problem of directionality. At the present time, an object coated in the material could appear invisible in one direction but fully visible in another.

Surmounting these barriers will take years, Yao said.
