While the finish given to our picture of the world by the theory of relativity has already been absorbed into the general scientific consciousness, this has scarcely occurred to the same extent with those aspects of the general problem of knowledge which have been elucidated by the quantum theory.
Interpretation
Niels Bohr suggests that while relativity is widely accepted in understanding the universe, quantum theory's implications for knowledge remain less understood.
In this quote, Niels Bohr reflects on the contrasting acceptance of two foundational theories in physics: relativity and quantum theory. He points out that although the implications of relativity have become well-integrated into scientific understanding and common consciousness, the deeper philosophical and conceptual challenges posed by quantum theory have not yet been fully realized or appreciated by society at large, emphasizing a gap in understanding the nature of knowledge itself.
In practice
In a lecture about the implications of quantum mechanics on modern science.
When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'
An independant reality in the ordinary physical sense can neither be ascribed to the phenomenon nor to the agencies of observation.
An expert is a man who has made all the mistakes which can be made, in a narrow field.
Those who are not shocked when they first come across quantum theory cannot possibly have understood it.
When searching for harmony in life one must never forget that in the drama of existence we are ourselves both actors and spectators.
And anyone who thinks they can talk about quantum theory without feeling dizzy hasn't yet understood the first thing about it.
Mitt Romney's energy policy is a relic of the 19th century. We need a 21st century plan. The fate of the planet is at stake.
In the distant future I see open fields for far more important researches. Psychology will be based on a new foundation, that of the necessary acquirement of each mental power and capacity by gradation. Light will be thrown on the origin of man and his history.
Wherever we look at the living biota … discontinuities are overwhelmingly frequent…The discontinuities are even more striking in the fossil record. New species usually appear in the fossil record suddenly, not connected with their ancestors by a series of intermediates.
Haemoglobin is a very large molecule by ordinary standards, containing about ten thousand atoms, but the chances are that your haemoglobin and mine are identical, and significantly different from that of a pig or horse. You may be impressed by how much human beings differ from one another, but if you were to look into the fine details of the molecules of which they are constructed, you would be astonished by their similarity.
To the field of synthetic chemistry belongs an array of responsibilities which are crucial for the future of mankind, not only with regard to the health and needs of our society, but also for the attainment of a deep understanding of matter, chemical change, and life.
It was strange, in a way, because there were no ideas involved in the laser that weren't already known by somebody 25 years before lasers were discovered. The ideas were all there; just, nobody put it together.
