Continual miniaturisation allows resources to be conserved, efficiency to be increased, pollution to be reduced, and the remarkable flexibilities of the quantum world to be tapped. Very advanced civilizations elsewhere in the universe may have been force to follow the same technological path. Their nano-scale space probes, their atomic-scale machines and nano-computers, would be imperceptible to our course-grained surveys of the universe.... This may be the low-impact evolutionary path you need to follow in order to survive into the far, far future.

Bertrand Russell had given a talk on the then new quantum mechanics, of whose wonders he was most appreciative. He spoke hard and earnestly in the New Lecture Hall. And when he was done, Professor Whitehead, who presided, thanked him for his efforts, and not least for 'leaving the vast darkness of the subject unobscured'.

If I were to propose to you that my arm could be in this position or in that position but it would be forbidden by the laws of nature to be in some intermediate position, that would likely strike you as absurd, as contrary to experience. And yet on the subatomic level, there is a quantization of energy and position and momentum. The reason that it seems counterintuitive is that is that we are not ordinarily down at the level of the very small, where quantum effects dominate.

Physics is at present a mass of partial theories which no man has yet been able to render truly and clearly consistent. It has been well said that the modern physicist is a quantum theorist on Monday, Wednesday, and Friday and a student of gravitational relativity theory on Tuesday, Thursday, and Saturday. On Sunday he is praying... that someone will find the reconciliation between the two views.

The theory of quantum electrodynamics describes Nature as absurd from the point of view of common sense. And it agrees fully with experiment. So I hope you accept Nature as She is — absurd.

Science, it is usually believed, helps us to build a picture of objective reality – the world 'out there'. With the advent of the quantum theory, that very reality appears to have crumbled, to be replaced by something so revolutionary and bizarre that its consequences have not yet been properly faced.

I have a more fractal way of working, if you like, it is more like the way most people's minds actually work. They don't work in any linear way. When your mind wanders if you ever pay attention to some of the paths it takes, you generally find it's these paths of association that can link all over the place. …The movements of the mind don't follow any linear pattern, they can't be explained with a mechanistic, clockwork view. You could find quantum models of how the mind works that might fit.

Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.

However the development proceeds in detail, the path so far traced by the quantum theory indicates that an understanding of those still unclarified features of atomic physics can only be acquired by foregoing visualization and objectification to an extent greater than that customary hitherto. We have probably no reason to regret this, because the thought of the great epistemological difficulties with which the visual atom concept of earlier physics had to contend gives us the hope that the abstracter atomic physics developing at present will one day fit more harmoniously into the great edifice of Science.

If we want to make relatively minor changes in our lives, we can perhaps appropriately focus on our attitudes and behaviors. But if we want to make significant, quantum change, we need to work on our basic paradigms.

Just by studying mathematics we can hope to make a guess at the kind of mathematics that will come into the physics of the future. A good many people are working on the mathematical basis of quantum theory, trying to understand the theory better and to make it more powerful and more beautiful. If someone can hit on the right lines along which to make this development, it may lead to a future advance in which people will first discover the equations and then, after examining them, gradually learn how to apply them.

Can quantum mechanics represent the fact that an electron finds itself approximately in a given place and that it moves approximately with a given velocity, and can we make these approximations so close that they do not cause experimental difficulties?

Having presented all the relevant nanoscale mechanisms, thus laying down a firm background for the readers' understanding, the author moves to the topic of architectural challenges in Chapter 7. This field is claimed still to be an unsolved problem so the author gives examples of currently used technologies and points out potential architectural solutions such as self-assembly, carbon nanotubes, or quantum systems. That is why it makes the book even more valuable for those who intend to involve nanonetworks in their research.

My brother Fairchild has just bought himself an "electronic janitor", a costly device which, I understand, keeps his house at an even temperature of 70 degrees without any effort on his part whatsoever. I don't know quite how it works, but it has something to do with molecules and the quantum theory.

If a woman has her PhD in physics, has mastered quantum theory, plays flawless Chopin, was once a cheerleader, and is now married to a man who plays baseball, she will forever be "former cheerleader married to star athlete."

Like anyone who is interested in science I was always interested in quantum mechanics, because it has so many bizarre philosophical implications. I have also been interested in what kind of knowledge you can have of people's intentions. It just seemed to me that there is a kind of parallel between physical uncertainty and people's intentions.

I like relativity and quantum theories because I don't understand them and they make me feel as if space shifted about like a swan that can't settle, refusing to sit still and be measured; and as if the atom were an impulsive thing always changing its mind.

As I realized what the abstract mathematics of quantum theory was actually saying, the world became a very strange place indeed. I became uncomfortable. I would like to share that discomfort with you.

It seems necessary to introduce in the laws in question a quantity foreign to classical electrodynamics, I.e., Planck's constant, or as it is often called, the elementary quantum of action.

Calculations that merge the equations of general relativity and those of quantum mechanic typically yield one and the same ridiculous answer: infinity. Like a sharp rap on the wrist from an old-time schoolteacher, an infinite answer is nature's way of telling us that we are doing something that is quite wrong.
