Copenhagen Famous Quotes

Slowly, numbed, I walk through the city's spring, the others' spring, the others' joyous transformation, the others' happiness. I'll never be famous, my poems are worthless. I'll marry a stable skilled worker who doesn't drink, or get a steady job with a pension. After that deadly disappointment, a long time passes before I write in my poetry album again. Even though no one else cares for my poems, I have to write them because it dulls the sorrow and longing in my heart.

As in Schrödinger’s cat, the famous thought experiment. Imagine a cat, a vial of poison, and a radioactive source in a sealed box. If an internal sensor registers radioactivity, like an atom decaying, the vial is broken, releasing a poison that kills the cat. The atom has an equal chance of decaying or not decaying. It’s an ingenious way of linking an outcome in the classical world, our world, to a quantum-level event. The Copenhagen interpretation of quantum mechanics suggests a crazy thing: before the box is opened, before observation occurs, the atom exists in superposition—an undetermined state of both decaying and not decaying. Which means, in turn, that the cat is both alive and dead. And only when the box is opened, and an observation made, does the wave function collapse into one of two states. In other words, we only see one of the possible outcomes. For instance, a dead cat. And that becomes our reality. But then things get really weird. Is there another world, just as real as the one we know, where we opened the box and found a purring, living cat instead? The Many-Worlds interpretation of quantum mechanics says yes. That when we open the box, there’s a branch. One universe where we discover a dead cat. One where we discover a live one. And it’s the act of our observing the cat that kills it—or lets it live. And then it gets mind-fuckingly weird. Because those kinds of observations happen all the time.

Thus, the EWG crowd claims that Copenhagenism violates Occam's economy by postulating a universe magically created by human thought. Because of the "is of identity" some Copenhagenists have actually gone that far. This led to Einstein's famous sarcasm that every time a mouse looks at the universe the universe must change; and Dr. Fred Allan Wolf has solemnly replied that the cells in the mouse's brain number so few that all the changes caused by all mouse observations total very, very little more than 0% and hence we can ignore them. I think Copenhagenism, as expressed in this book, without the "is of identity" evades the above criticism. (We will shortly ponder whether another alternative, hidden variable theories, can similarly evade the EWG criticism when restated without the "is of identity.")

Another famous town planning concept, the Finger Plan for Copenhagen, was based on a metaphor sand shown by a diagram, of a great hand resting over that city. Since 1947, the great hand has guided Copenhagen’s development. The merchant’s harbour, after which the city was named, sits in the palm of the guiding hand. Fingers point ways to new development. Power lines, telecom lines, and rapid transit lines follow the bones, arteries, veins and nerves of the fingers. Between those fingers we find the green lands of Denmark. Copenhagen was made into a garden city but the hand itself, of urban development, was grey.
