A certain ounce of arrogance is not essential in carrying forward an idea. In talking about the device with others, surprising now number of people who either were quite negative and had reasons to suggest it would not function as described or claimed that it would be of little interest and no better than some already existing device.
Light, properly so called, is only a narrowly defined part of a far greater phenomenon, that of radiation in general.... The lengths of [visible] light waves fall between close limits; but the rules of wave motion apply to the infinitesimal waves of X-rays on one hand and to the long radio waves on the other.
Science doesn't always go forwards. It's a bit like doing a Rubik's cube. You sometimes have to make more of a mess with a Rubik's cube before you can get it to go right. You build up this picture of what there is and you believe it to be true and you work with this picture and you refine it but sometimes you have to abandon the picture. Sometimes you discover the picture you thought you had, that everybody thought we had, actually turns out to be wrong.
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.
The structure of the human brain is enormously complex. It contains about 10 billion nerve cells (neurons), which are interlinked in a vast network through 1,000 billion junctions (synapses). The whole brain can be divided into subsections, or sub-networks, which communicate with each other in a network fashion. All this results in intricate patterns of intertwined webs, networks of nesting within larger networks.
History of science played a very important role for me. Before I knew well how to do an experiment, I knew why Joliot has missed the neutron, why his wife missed the fission, why they succeeded in having artificial radioactivity, and even why they almost missed the other things, by doing very nice experiments, but didn't come to the conclusion. That is science. Science is doubt, is research. It is not something which is – and that is the danger of teaching – which is too academic and which the people explain you it is like the logic thing that comes out of the computer, which is not true. You have intuition, you have passion.
