I can calculate the motion of heavenly bodies, but not the madness of people.
Sir Isaac Newton
The only laws of matter are those that our minds must fabricate and the only laws of mind are fabricated for it by matter.
James Clerk Maxwell
Nothing is to wonderful to be true
I have learned more from my mistakes than from my successes.
Sir Humphrey Davy
Every moment dies a man,
Every moment 1 1/16 is born.
A point of great importance would be first to know: what is the capacity of the earth? And what charge does it contain if electrified? Though we have no positive evidence of a charged body existing in space without other oppositely electrified bodies being near, there is a fair probability that the earth is such a body, for by whatever process it was separated from other bodies — and this is the accepted view of its origin — it must have retained a charge, as occurs in all processes of mechanical separation.
It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present. But if (and oh! what a big if!) we could conceive in some warm little pond, with all sorts of ammonia and phosphoric salts, light, heat, electricity, &c., present, that a proteine compound was chemically formed ready to undergo still more complex changes, at the present day such matter would be instantly absorbed, which would not have been the case before living creatures were found.
Charles R Darwin
The mind of man may be compared to a musical instrument with a certain range of notes, beyond which in both directions we have an infinitude of silence.
I can assure you that there is the greatest practical benefit in making a few failures early in life
Thomas H Huxley
Some of the most famous books are the least worth reading. Their fame was due to their having done something that needed to be doing in their day. The work is done and the virtue of the book has expired.
How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love?
