20th-century Physicist Quotes
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.
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.
Research is a matter of overcoming obstacles. That's what research is about. There are problems. There are difficulties. It's hard to make sense of a collection of information or whatever. Obstacles are the nature of research. Maybe that's why some people give up. There's always an obstacle. You overcome one to find there's another one.
One can see clearly some ambivalence in Dirac's attitudes... On the one hand, he has repeated many, many times his conviction that beauty in the fundamental equations of physics has priority... On the other hand... we see Dirac deeply involved with approximate calculations whose only purpose was to obtain an answer which the experimenters could rely upon.
Human beings are organisms capable of manipulating internal representations of the world by means of concrete operations and can transcend the bounds of their biologically given perceptions. They can liberate themselves and construct a view of reality that conflicts with intuition, yet gives a true, more encompassing view.
