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.'

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?
Interpretation
What this quote means
The quote questions why, despite the vastness and potential of the universe, we have not encountered extraterrestrial life.
Enrico Fermi's quote highlights a paradox in the search for extraterrestrial civilizations, known as the Fermi Paradox. It posits that given the age of the universe and the potential for life to arise elsewhere, we should have observable evidence of advanced civilizations, yet we find none. This raises fundamental questions about the existence of other life forms, the nature of intelligence, and the future of humanity in the cosmos.

All quotes βThe 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.

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.

Government! Three-fourths parasitic and the rest stupid fumbling - oh, Harshaw concluded that man, a social animal, could not avoid government, any more than an individual could escape bondage to his bowels. But simply because an evil was inescapable was no reason to term it "good." He wished that government would wander off and get lost! (96)

You know the theory of cell irritability? If you take an amoeba cell and poke it a thousand times, it will change and then re-form into its original shape. And then, the thousandth time you poke this amoeba, the cell will completely collapse and become nothing. That's kind of what it's like being famous. People say hi, how are you doing, and after the thousandth time, you just get angry; you really pop.
