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.

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.

The recollections of an older man are different from those of a younger man. What seemed vital at forty may lose its significance at seventy. We manufacture stories, after all, from the fleeting sensory material that bombards us at every instant, a fragmented series of pictures, conversations, odors, and the touch of things and people. We delete most of it to live with some semblance of order, and the reshuffling of memory goes on until we die.
That the Jews are connected with God in a special way and that God does not allow that bond to fail is entirely obvious. We wait for the instant in which Israel will say yes to Christ, but we know that it has a special mission in history now ... which is significant for the world.
Not keep a journal! How are your absent cousins to understand the tenor of your life in Bath without one? How are the civilities and compliments of every day to be related as they ought to be, unless noted down every evening in a journal? How are your various dresses to be remembered, and the particular state of your complexion, and curl of your hair to be described in all their diversities, without having constant recourse to a journal?
