On certain occasions, the eyes of the mind can supply the want of the most powerful telescopes, and lead to astronomical discoveries of the highest importance.
Francois AragoRead
In the experimental sciences, the epochs of the most brilliant progress are almost always separated by long intervals of almost absolute repose.
Interpretation
Scientific progress often occurs in bursts, interspersed with long periods of stagnation.
Francois Arago highlights that in the field of experimental sciences, significant advancements tend to come in sudden bursts, but these breakthroughs are typically preceded and followed by lengthy periods of little activity or progress. This suggests that innovation and discovery are often not continuous processes but rather punctuated by phases of rest or inactivity, reflecting the complexities of scientific research and its inherent rhythm.
In practice
During a lecture on scientific advancement, one might mention this quote to illustrate the nature of breakthroughs.
On certain occasions, the eyes of the mind can supply the want of the most powerful telescopes, and lead to astronomical discoveries of the highest importance.
Given exponential growth dynamics of infectious diseases, containing an epidemic is straightforward early on, but nearly impossible once a disease spreads among a population.
A good science fiction story is a story with a human problem, and a human solution, which would not have happened at all without its science content.
The history of acceptance of new theories frequently shows the following steps: At first the new idea is treated as pure nonsense, not worth looking at. Then comes a time when a multitude of contradictory objections are raised, such as: the new theory is too fancy, or merely a new terminology; it is not fruitful, or simply wrong. Finally a state is reached when everyone seems to claim that he had always followed this theory. This usually marks the last state before general acceptance.
If you represent the Earth's lifetime by a single year, say from January when it was made to December, the 21st-century would be a quarter of a second in June - a tiny fraction of the year. But even in this concertinaed cosmic perspective, our century is very, very special: the first when humans can change themselves and their home planet.
The math of quantum mechanics and the math of general relativity, when they confront one another, they are ferocious antagonists and the equations don't work.
The recurrence of a phenomenon like Edison is not very likely. The profound change of conditions and the ever increasing necessity of theoretical training would seem to make it impossible. He will occupy a unique and exalted position in the history of his native land, which might well be proud of his great genius and undying achievements in the interest of humanity.
