It is not a simple matter to differentiate unsuccessful from successful experiments. . . .[Most] work that is finally successful is the result of a series of unsuccessful tests in which difficulties are gradually eliminated.
Interpretation
Success often comes after many failures, as each setback helps refine the approach.
This quote by Robert H. Goddard emphasizes that distinguishing between unsuccessful and successful experiments is not straightforward. It highlights the reality that many successful outcomes are achieved only after undergoing a series of trials, where each failure teaches valuable lessons and gradually removes obstacles. This reflects the iterative nature of scientific inquiry and progress, stressing the importance of perseverance and learning from mistakes.
In practice
In a motivational speech about innovation and resilience in the face of failure.
How many more years I shall be able to work on the problem I do not know; I hope, as long as I live. There can be no thought of finishing, for 'aiming at the stars' both literally and figuratively, is a problem to occupy generations, so that no matter how much progress one makes, there is always the thrill of just beginning.
It is difficult to say what is impossible, for the dream of yesterday is the hope of today and the reality of tomorrow.
The only barrier to human development is ignorance, and this is not insurmountable.
Every vision is a joke until the first man accomplishes it; once realized, it becomes commonplace.
The problem with intelligent-design theory, is not that it is false but that it is not falsifiable. Not being susceptible to contradicting evidence, it is not a testable hypothesis. Hence it is not a scientific but a creedal tenet - a matter of faith, unsuited to a public school's science curriculum.
We have this very clean picture of science, you know, these well-established rules with which we make predictions. But when you're really doing science, when you're doing research, you're at the edge of what we know.
The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.
Small-scale fisheries should not be favoured over large-scale operations ebcause of romantic notions of rugged small operators battling both the elements and anonymous corporations. [They ought to be supported] because of the scientific evidence available to confirm the common-sense inference that local fishers, if given privileged access, will tend to avoid trashing their local stocks, while foreign fishers do not have such motivation.
As in nature, all is ebb and tide, all is wave motion, so it seems that in all branches of industry, alternating currents - electric wave motion - will have the sway.
I belonged to a small minority of boys who were lacking in physical strength and athletic prowess. ... We found our refuge in science. ... We learned that science is a revenge of victims against oppressors, that science is a territory of freedom and friendship in the midst of tyranny and hatred.
