Creating a new theory is not like destroying an old barn and erecting a skyscraper in its place. It is rather like climbing a mountain, gaining new and wider views, discovering unexpected connections between our starting points and its rich environment. But the point from which we started out still exists and can be seen, although it appears smaller and forms a tiny part of our broad view gained by the mastery of the obstacles on our adventurous way up.
Interpretation
Developing new theories involves gradual exploration and understanding rather than a complete overhaul of previous ideas.
In this quote, Albert Einstein emphasizes that creating new theories is a process of exploration and gradual understanding rather than a simple act of replacing outdated concepts. He compares it to climbing a mountain, where each step provides new perspectives and insights, allowing one to see how earlier thoughts contribute to a broader understanding of the subject matter. The original ideas still hold significance, even as one's view expands with new knowledge.
In practice
In a lecture about scientific progress, this quote can illustrate the nature of theory development.
I cannot then believe in this concept of an anthropomorphic God who has the powers of interfering with these natural laws. As I said before, the most beautiful and most profound religious emotion that we can experience is the sensation of the mystical. And this mysticality is the power of all true science.
If I would follow your advice and Jesus could perceive it, he, as a Jewish teacher, surely would not approve of such behavior.
I want to know all Gods thoughts; all the rest are just details.
In the middle of adversity there is great opportunity.
I do not believe that civilization will be wiped out in a war fought with the atomic bomb. Perhaps two-thirds of the people of the earth will be killed.
To me the worst thing seems to be a school principally to work with methods of fear, force and artificial authority. Such treatment destroys the sound sentiments, the sincerity and the self-confidence of pupils and produces a subservient subject.
All of a sudden, space isn't friendly. All of a sudden, it's a place where people can die. . . . Many more people are going to die. But we can't explore space if the requirement is that there be no casualties; we can't do anything if the requirement is that there be no casualties.
Psychology, as the behaviorist views it, is a purely objective, experimental branch of natural science which needs introspection as little as do the sciences of chemistry and physics.... The position is taken here that the behavior of man and the behavior of animals must be considered in the same plane.
There is no branch of mathematics, however abstract, which may not some day be applied to phenomena of the real world.
Those who say that climate change doesn't exist are being understood as the flat-earthers that they are, as the people who deny the link between smoking and cancer, as the people who denied the link between HIV and AIDS.
I think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of great value to realize that we do not know the answers to different questions. This attitude of mind - this attitude of uncertainty - is vital to the scientist, and it is this attitude of mind which the student must first acquire.
An experiment is a question which science poses to Nature and a measurement is the recording of Nature's answer.
