Quotes About Quantum

Deoarece principiul de incertitudine nu permite s? avem valori exacte atât pentru câmp, cât È™i pentru viteza lui de variaÈ›ie, spaÈ›iul nu e niciodat? gol. El poate avea o starea de energie minim?, numit? vid, dar acea stare e supus? la ceea ce numim fluctuaÈ›ii cuantice sau fluctuaÈ›ii ale vidului.

If information is lost in macroscopic black holes it should also be lost in processes in which microscopic, virtual black holes appear because of quantum fluctuations of the metric. One could imagine that particles and information could fall into these holes and get lost. Maybe that is where all those odd socks went.

Of course, any scenario involving quantum mechanics in the origin of life three billion years ago remains highly speculative. But, as we have discussed, even classical explanations of life's origin are beset with problems: it isn't easy to make life from scratch!

Quantum mechanics is normal. It is the world it describes that is weird.

it was known that genes could be faithfully transmitted with mutation rates (errors) of less than one in one billion. This extraordinary high degree of fidelity convinced Schrödinger that the laws of heredity could not be founded on the "order from disorder" classical laws. Instead, he proposed that genes were more like individual atoms or molecules in being subject to the nonclassical but strangely orderly rules of the science he helped to found, quantum mechanics.

Much of the skepticism Schrödinger's claim attracted at the time was rooted in the general belief that delicate quantum states couldn't possibly survive in the warm, wet and busy molecular environments inside living organisms

between the quantum and classical worlds, the quantum edge, where we, as you will have guessed from the title of this book, are claiming life also lies.

Life appears to have one foot in the classical world of everyday objects and the other planted in the strange and peculiar depths of the quantum world. Life, we will argue, lives on the quantum edge.

entanglement is a quantum step up from coherence whereby quantum particles lose their individuality, so that what happens to one affects them all, instantaneously.

Schrödinger's seventy-year-old insight that the kinds of living system that are likely to support quantum rules will involve small numbers of particles.

there is in fact no evidence that quantum mechanics is actually needed at all to account for consciousness—unlike other biological phenomena that we have considered in this book such as enzyme action or photosynthesis.

The British philosopher and novelist Raymond Tallis, writing in the New Scientist (January 2010), commented on how the 'material world, far from being the noisy, colourful, smelly place we live in, is colourless, silent, full of odourless molecules, atoms, particles, whose nature and behaviour is best described mathematically'.

This is why magic is worse even than quantum physics. Because, while both spit in the eye of common sense, I've never yet had a Higgs bosun turn up and try to have a conversation with me.

A)ny working hypothesis was probably going to involve quantum theory at some point—the part of physics that made my brains trickle out of my ears.

There are relatively few experiments in atomic physics these days that don't involve the use of a laser.

The math of quantum mechanics and the math of general relativity, when they confront one another, they are ferocious antagonists and the equations don't work.

In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.

We might feel very sure that there is no more to reality that the material world in which we live, but we cannot prove that this is the case. Theoretically there could be other realms, other dimensions, as all religious traditions and quantum physics alike maintain. Theoretically, the brain could be as much a receiver as a generator of consciousness and thus might be fine-tuned in altered states to pick up wavelengths that are normally not accessible to us.

Their math lacks integers!" "As far as we can tell," Jennifer added. "They don't use whole numbers at all. Only 'smears,' they call them.

bosons—photons, and so on— are in some respects strongly tied to spacetime. Their wavelengths expand as the universe expands.

Feynman once said that if you understand quantum theory, you don't. I had no idea what Lisa was talking about.

Hugh Everett's work has been described by many people in terms of many worlds, the idea being that every one of the various alternative histories, branching histories, is assigned some sort of reality.

The qubit acts as a bridge between the microscopic and the macroscopic worlds.

So what I'm saying is why don't we think about changing Schrodinger's equation at some level when masses become too big at the level that you might have to worry about Einstein's general relativity.
