17548 | Maxwell introduced real fields, which transferred forces from point to point [Heisenberg] |
Full Idea: In the theory of fields of force one came back to the older idea, that action is transferred from one point to a neighbouring point. ...With Maxwell the fields of force seemed to have acquired the same degree of reality as the body's of Newton's theory. | |
From: Werner Heisenberg (Physics and Philosophy [1958], 06) |
17533 | Radiation interference needs waves, but radiation photoelectric effects needs particles [Heisenberg] |
Full Idea: How could it be that the same radiation that produces interference patterns, and therefore must consist of waves, also produces the photoelectric effect, and therefore must consist of moving particles. | |
From: Werner Heisenberg (Physics and Philosophy [1958], 02) |
17537 | Position is complementary to velocity or momentum, so the whole system is indeterminate [Heisenberg] |
Full Idea: The knowledge of the position of a particle is complementary to the knowledge of its velocity or momentum. If we know one with high accuracy we cannot know the other with high accuracy; still we must know both for determining the behaviour of the system. | |
From: Werner Heisenberg (Physics and Philosophy [1958], 03) | |
A reaction: This is the famous Uncertainty Principle, expressed in plain language by the man himself. At this point we lost our grip on the prospects of determining the behaviour of natural systems. |
17532 | An atom's stability after collisions needs explaining (which Newton's mechanics can't do) [Heisenberg] |
Full Idea: The first new model of the atom could not explain the most characteristic features of the atom, its enormous stability. No planetary system following the laws of Newton's mechanics would ever go back to its original configuration after a collision. | |
From: Werner Heisenberg (Physics and Philosophy [1958], 02) |
17551 | It was formerly assumed that electromagnetic waves could not be a reality in themselves [Heisenberg] |
Full Idea: The idea that electromagnetic waves could be a reality in themselves, independent of any bodies, did at that time not occur to the physicists. | |
From: Werner Heisenberg (Physics and Philosophy [1958], 07) | |
A reaction: 'At that time' is when they thought the waves must travel through something, called the 'ether'. |
