I remember my friend Johnny von Neumann used to say, 'with four parameters I can fit an elephant and with five I can make him wiggle his trunk.'

Interpretation

What this quote means

The quote humorously highlights the flexibility and limitations of models in science and data fitting.

Enrico Fermi's quote serves as a witty reminder of the power and absurdity of mathematical models in science. It suggests that while one can create complex models to fit data, these models can also become overly complicated or disconnected from reality when adorned with excessive parameters. The essence is that fitting a model should maintain a balance between accuracy and simplicity to retain its usefulness.

Where is everybody? Humans could theoretically colonize the galaxy in a million years or so, and if they could, astronauts from older civilizations could do the same. So why haven't they come to Earth?

The fact that no limits exist to the destructiveness of this weapon [the 'Super', i.e. the hydrogen bomb] makes its very existence and the knowledge of its construction a danger to humanity as a whole. It is necessarily an evil thing considered in any light. For these reasons, we believe it important for the President of the United States to tell the American public and the world what we think is wrong on fundamental ethical principles to initiate the development of such a weapon.

Never underestimate the joy people derive from hearing something they already know.

Experimental confirmation of a prediction is merely a measurement. An experiment disproving a prediction is a discovery.

Whatever Nature has in store for mankind, unpleasant as it may be, men must accept, for ignorance is never better than knowledge.

One might be led to question whether the scientists acted wisely in presenting the statesmen of the world with this appalling problem. Actually there was no choice. Once basic knowledge is acquired, any attempt at preventing its fruition would be as futile as hoping to stop the earth from revolving around the sun.

Here we were, the only seven humans in space, repairing a telescope whose only purpose is to enrich the minds of people on planet Earth and increase our understanding of the workings of the universe. I can think of no better peaceful use of space for all humankind.

The dimmed outlines of phenomenal things all merge into one another unless we put on the focusing-glass of theory, and screw it up sometimes to one pitch of definition and sometimes to another, so as to see down into different depths through the great millstone of the world.

On two occasions I have been asked, 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

How strange it would be if the final theory were to be discovered in our lifetimes! The discovery of the final laws of nature will mark a discontinuity in human intellectual history, the sharpest that has occurred since the beginning of modern science in the seventeenth century. Can we now imagine what that would be like?
