Science, my lad, has been built upon many errors; but they are errors which it was good to fall into, for they led to the truth.
Interpretation
Science progresses through mistakes that ultimately lead to greater truths.
This quote by Jules Verne emphasizes the idea that scientific advancement often involves making errors. Each mistake serves as a stepping stone toward a more accurate understanding of the truth, illustrating the iterative nature of scientific discovery where failure is not just an obstacle, but a valuable part of the learning process.
In practice
This quote can be used in a presentation about the scientific method to illustrate the value of learning from mistakes.
Travel enables us to enrich our lives with new experiences, to enjoy and to be educated, to learn respect for foreign cultures, to establish friendships, and above all to contribute to international cooperation and peace throughout the world.
It is always a vulgar and often an unhealthy pastime, and it is a vice which does not go alone; the man who gambles will find himself capable of any evil.
Nothing can astound an American. It has often been asserted that the word 'impossible' is not a French one. People have evidently been deceived by the dictionary. In America, all is easy, all is simple; and as for mechanical difficulties, they are overcome before they arise.
However strong, however imposing a ship may appear, it is not 'disgraced' because it flies before the tempest. A commander ought always to remember that a man's life is worth more than the mere satisfaction of his own pride. In any case, to be obstinate is blameable, and to be wilful is dangerous.
The Yankees, the first mechanicians in the world, are engineers - just as the Italians are musicians and the Germans metaphysicians - by right of birth. Nothing is more natural, therefore, than to perceive them applying their audacious ingenuity to the science of gunnery.
Nothing is more dreadful than private duels in America. The two adversaries attack each other like wild beasts. Then it is that they might well covet those wonderful properties of the Indians of the prairies - their quick intelligence, their ingenious cunning, their scent of the enemy.
If a given scientist had not made a given discovery, someone else would have done so a little later. Johann Mendel dies unknown after having discovered the laws of heredity: thirty-five years later, three men rediscover them. But the book that is not written will never be written. The premature death of a great scientist delays humanity; that of a great writer deprives it.
One does not have to appeal to God to set the initial conditions for the creation of the universe, but if one does He would have to act through the laws of physics.
The search for knowledge is in our genes. It was put there by our distant ancestors who spread across the world, and it's never going to be quenched.
The dramatic importance of climate changes to the worldβs future has been dangerously underestimated by many, often because we have been lulled by modern technology into thinking we have conquered nature. This well-written book points out in clear language that the climatic threat could be as awesome as any we might face, and that massive world-wide actions to hedge against that threat deserve immediate consideration.
We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.
Our great struggle in medicine these days is not just with ignorance and uncertainty. It's also with complexity: how much you have to make sure you have in your head and think about. There are a thousand ways things can go wrong.
