184a Since, in all pursuits in which there are sources or causes or elements, it is by way of our acquaintance with these that knowing and understanding come to us (for we regard ourselves as knowing each thing whenever we are acquainted with its first causes and first beginnings, even down to its elements), it is…
For 99 per cent of the tenure of humans on earth, nobody could read or write. The great invention had not yet been made. Except for first-hand experience, almost everything we knew was passed on by word of mouth. As in the game of 'Chinese Whispers', over tens and hundreds of generations, information would slowly be…
One of the great commandments of science is, 'Mistrust arguments from authority'. (Scientists, being primates, and thus given to dominance hierarchies, of course do not always follow this commandment.) Too many such arguments have proved too painfully wrong. Authorities must prove their contentions like everybody…
It was from Kuiper that I first got a feeling for what is called a back-of-the-envelope calculation: a possible explanation to a problem occurs to you, you pull out an old envelope, appeal to your knowledge of fundamental physics, scribble a few approximate equations on the envelope, substitute in likely numerical…
It is necessary for the Bible, in order to be accommodated to the understanding of every man, to speak many things which appear to differ from the absolute truth so far as the bare meaning of the words is concerned. But Nature, on the other hand, is inexorable and immutable; she never transgresses the laws imposed…
Instead of being ashamed that so little has been hitherto done by female abilities, in science and in useful literature, I am surprised that so much has been effected. Till of late, women were kept in Turkish ignorance; every means of acquiring knowledge was discountenanced by fashion, and impracticable even to those…
As individuals, we are amazingly ignorant and incapable. How many of us, alone in a wilderness, could make a flint knife? Is there anyone now alive who knows even a tenth of everything there is to know in science? How many of those employed in the electricity industry could make any of its components, such as wires or…
One way, that's kind of a fun analogy in trying to get some idea of what we're doing in trying to understand nature, is to imagine that the gods are playing some great game like chess, let's say, and you don't know the rules of the game, but you're allowed to look at the board, at least from time to time, in a little…
