Prince Louis-Victor de Broglie
(15 Aug 1892 - 19 Mar 1987)

French physicist who made contributions to quantum wave mechanics and won the 1929 Nobel Prize for Physics in recognition of his discovery of the wave nature of the electron.


Science Quotes by Prince Louis-Victor de Broglie (6 quotes)

After long reflection in solitude and meditation, I suddenly had the idea, during the year 1923, that the discovery made by Einstein in 1905 should be generalised by extending it to all material particles and notably to electrons.
— Prince Louis-Victor de Broglie
Preface to his re-edited 1924 Ph.D. Thesis, Recherches sur la théorie des quanta (1963), 4. In Steve Adams, Frontiers (2000), 13.
Science quotes on:  |  Albert Einstein (535)  |  Electron (66)  |  Idea (440)  |  Particle (90)  |  Wave (55)

Many scientists have tried to make determinism and complementarity the basis of conclusions that seem to me weak and dangerous; for instance, they have used Heisenberg's uncertainty principle to bolster up human free will, though his principle, which applies exclusively to the behavior of electrons and is the direct result of microphysical measurement techniques, has nothing to do with human freedom of choice. It is far safer and wiser that the physicist remain on the solid ground of theoretical physics itself and eschew the shifting sands of philosophic extrapolations.
— Prince Louis-Victor de Broglie
New Perspectives in Physics (1962), viii.
Science quotes on:  |  Electron (66)  |  Free Will (11)  |  Werner Heisenberg (38)  |  Quantum Physics (16)  |  Theoretical Physics (15)  |  Uncertainty Principle (7)

Science itself, no matter whether it is the search for truth or merely the need to gain control over the external world, to alleviate suffering, or to prolong life, is ultimately a matter of feeling, or rather, of desire-the desire to know or the desire to realize.
— Prince Louis-Victor de Broglie
New Perspectives in Physics (1962), 196.
Science quotes on:  |  Philosophy Of Science (5)  |  Science (1699)  |  Truth (750)

There is no reason why the history and philosophy of science should not be taught in such a way as to bring home to all pupils the grandeur of science and the scope of its discoveries.
— Prince Louis-Victor de Broglie
New Perspectives in Physics (1962), 195.
Science quotes on:  |  Discovery (591)  |  History Of Science (53)  |  Philosophy Of Science (5)

Thus with every advance in our scientific knowledge new elements come up, often forcing us to recast our entire picture of physical reality. No doubt, theorists would much prefer to perfect and amend their theories rather than be obliged to scrap them continually. But this obligation is the condition and price of all scientific progress.
— Prince Louis-Victor de Broglie
New Perspectives in Physics (1962), 31.
Science quotes on:  |  Knowledge (1128)  |  Progress (317)  |  Scientific Progress (12)  |  Theory (582)

Vulnerable, like all men, to the temptations of arrogance, of which intellectual pride is the worst, he [the scientist] must nevertheless remain sincere and modest, if only because his studies constantly bring home to him that, compared with the gigantic aims of science, his own contribution, no matter how important, is only a drop in the ocean of truth.
— Prince Louis-Victor de Broglie
New Perspectives in Physics (1962), 215.
Science quotes on:  |  Arrogance (12)  |  Men Of Science (97)  |  Pride (45)  |  Truth (750)



Quotes by others about Prince Louis-Victor de Broglie (1)

Long may Louis de Broglie continue to inspire those who suspect that what is proved by impossibility proofs is lack of imagination.
In 'On the Impossible Pilot Wave', Foundations of Physics (Oct 1982), 12, No. 10, 989-999. Reprinted in Speakable and Unspeakable in Quantum Mechanics (1987), 167.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
