Whoever wishes to acquire a deep acquaintance with Nature must observe that there are analogies which connect whole branches of science in a parallel manner, and enable us to infer of one class of phenomena what we know of another. It has thus happened on several occasions that the discovery of an unsuspected analogy between two branches of knowledge has been the starting point for a rapid course of discovery.
Interpretation
Understanding nature requires recognizing connections between different scientific fields.
William Stanley Jevons emphasizes the importance of observing analogies across various branches of science. By identifying these connections, one can leverage knowledge from one area to gain insights into another, often leading to significant discoveries and advancements in understanding natural phenomena.
In practice
In a scientific conference discussing the relationship between physics and biology, a speaker might use this quote to emphasize interdisciplinary collaboration.
It is clear that Economics, if it is to be a science at all, must be a mathematical science ... simply because it deals with quantities... As the complete theory of almost every other science involves the use of calculus, so we cannot have a true theory of Economics without its aid.
Value is the most invincible and impalpable of ghosts, and comes and goes unthought of, while the visible and dense matter remains as it was.
Back in my days as a chemistry student, I used to be quite a technocrat. I was firmly convinced that scientists would have cornered God and photographed Him in color by 1951.
But the beauty of Einstein's equations, for example, is just as real to anyone who's experienced it as the beauty of music. We've learned in the 20th century that the equations that work have inner harmony.
If you come from mathematics, as I do, you realize that there are many problems, even classical problems, which cannot be solved by computation alone.
But in most cases even the possibility that the correlations reflect shared genes is taboo.
Climate change, demographics, water, food, energy, global health, women's empowerment - these issues are all intertwined. We cannot look at one strand in isolation. Instead, we must examine how these strands are woven together.
Nuclear accidents anywhere can affect people everywhere.
