Elpino. Why then do we not see the other bright bodies which are earths circling around the bright bodies which are suns? For beyond these we can detect no motion whatever; and why do all other mundane bodies (except those known as comets) appear always in the same order and at the same distance? Philotheo. The reason…
Another way of describing the revolution in physics is to say that the key moves and acts, physicists do not care; 'matter' to them means 'to matter'. moves and acts, physicists do not care; 'matter' to them means 'to matter', to make a difference. But our language is still geared to express 'states of being', rather…
The difference between a piece of stone and an atom is that an atom is highly organised, whereas the stone is not. The atom is a pattern, and the molecule is a pattern, and the crystal is a pattem; but the stone, although it is made up of these pattems, is just a mere confusion. It's only when life appears that you…
In thinking about hidden layers, it’s important to distinguish between the routine efficiency and power of a good network, once that network has been set up, and the difficult issue of how to set it up in the first place. That difference is reflected in the difference between playing the piano (or, say, riding a…
In America here, life expectancy for the average woman is 80. But for an Adventist woman, their life expectancy is 89. And the difference is even more pronounced among men, who are expected to live about 11 years longer than their American counterparts. Now, this is a study that followed about 70,000 people for 30…
...older people in traditional societies have a huge significance that would never occur to us in our modern, literate societies, where our sources of information are books and the Internet. In contrast, in traditional societies without writing, older people are the repositories of information. It's their knowledge…
The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them…
When you say exergasia, synathroesmus, and incrementum together in a list, it seems to me that you have thereby given an example of all three devices in that same phrase.” Swan snorted at this. “How so, Socrates?” “ ‘Exergasia’ means ‘use of different phrases to express the same idea,’ ‘synathroesmus’ means…
As we move from the "low" level to the "high", say from the domain of machine code all the way up to, for instance, a rich, expressive Ruby DSL, the question arises, as it does for all language: have we acquired a surplus of content that cannot be simply reduced to core rules? At this point things get less…
I shall here insert a problem of that very ingenious and studious promoter of real knowledge, the learned and worthy Mr. Molyneux, which he was pleased to send me in a letter some months since; and it is this:- "Suppose a man born blind, and now adult, and taught by his touch to distinguish between a cube and a sphere…
Lorenz and his team were working to develop a weather forecasting program on an early computer known as a Royal McBee LGP-30.21 They thought they were getting somewhere until the computer started spitting out erratic results. They began with what they thought was exactly the same data and ran what they thought was…
To dissimulate is to pretend not to have what one has. To simulate is to feign to have what one doesn't have. One implies a presence, the other an absence. But it is more complicated than that because simulating is not pretending: "Whoever fakes an illness can simply stay in bed and make everyone believe he is ill…
The History of Evolution of Organisms consists of two kindred and closely connected parts: Ontogeny, which is the history of the evolution of individual organisms, and Phylogeny, which is the history of the evolution of organic tribes. Ontogency is a brief and rapid recapitulation of Phylogeny, dependent on the…
Run the tape again, and let the tiny twig of Homo sapiens expire in Africa. Other hominids may have stood on the threshold of what we know as human possibilities, but many sensible scenarios would never generate our level of mentality. Run the tape again, and this time Neanderthal perishes in Europe and Homo erectus…
The genome is not a blueprint for constructing a body; it is a recipe for baking a body. As the hox story illustrates, DNA promoters express themselves in the fourth dimension; their timing is all. A chimp has a different head from a human being not because it has a different blueprint for the head, but because it…
The inventor and the research man are confused because they both examine results of physical or chemical operations. But they are exact opposites, mirror images of one another. The research man does something and does not care [exactly] what it is that happens, he measures whatever it is. The inventor wants something…
There is only one law of Nature—the second law of thermodynamics—which recognises a distinction between past and future more profound than the difference of plus and minus. It stands aloof from all the rest. ... It opens up a new province of knowledge, namely, the study of organisation; and it is in connection with…
Geology has its peculiar difficulties, from which all other sciences are exempt. Questions in chemistry may be settled in the laboratory by experiment. Mathematical and philosophical questions may be discussed, while the materials for discussion are ready furnished by our own intellectual reflections. Plants, animals…
I could not help laughing at the ease with which he explained his process of deduction. 'When I hear you give your reasons,' I remarked, 'the thing always appears to me to be so ridiculously simple that I could easily do it myself, though at each successive instance of your reasoning I am baffled, until you explain…
Openness has several facets, but all are rooted in the same two principles: embracing your own fallibility and embracing diversity. Secularists, being human, are as prone as anyone to cling stubbornly to our opinions once they’re established. Openness includes recognizing our own fallibility: No matter how thoroughly…
