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.
Windmills installed around the world converting their direct current into alternating current and feeding the electric energy into the world network can harvest the planet Earth's prime daily energy income source-the wind--and adequately supply all the world's energy needs
From a certain temperature on, the molecules 'condense' without attractive forces; that is, they accumulate at zero velocity. The theory is pretty, but is there some truth in it.
Science affects the average man and woman in two ways already. He or she benefits by its application driving a motor-car or omnibus instead of a horse-drawn vehicle, being treated for disease by a doctor or surgeon rather than a witch, and being killed with an automatic pistol or shell in place of a dagger or a battle-axe.
We have to have a combination of general relativity that describes the warping of space and time, and quantum physics, which describes the uncertainties in that warping and how they change.
In the past, there was active discrimination against women in science. That has now gone, and although there are residual effects, these are not enough to account for the small numbers of women, particularly in mathematics and physics.
I take no pleasure in the fact that the scientific predictions I’ve relayed to popular audiences turn out to be true.
