The Center of the Earth
Of all regions of the earth none invites speculation more than that which lies beneath our feet, and in none is speculation more dangerous; yet, apart from speculation, it is little that we can say regarding the constitution of the interior of the earth. We know, with sufficient accuracy for most purposes, its size and shape: we know that its mean density is about 5½ times that of water, that the density must increase towards the centre, and that the temperature must be high, but beyond thes...Invites speculation and is the realm of mathematics, not observation.

God of the Gaps
The man in the street will, therefore, twist the statement that the scientist has come to the end of meaning into the statement that the scientist has penetrated as far as he can with the tools at his command, and that there is something beyond the ken of the scientist. This imagined beyond, which the scientist has proved he cannot penetrate, will become the playground of the imagination of every mystic and dreamer. The existence of such a domain will be made the basis of an orgy of rationali...The gaps in what science knows gets filled with gods and ghosts, but the atheist also fills it with the idea that chance rules the universe.

Children Learn New Languages More Easily Than Adults
Other, less tragic kinds of evidence also support this idea. Most people have a much more difficult time learning a second language late in life than they do in childhood. Immigrants may try to learn the language of their new country, only to be outdone by their own children. When we visit a foreign country for a while, our kids seem to be happily chatting with the other kids in the playground, while we are still painfully looking through the phrase books. When we learn a second language past...It is best to teach someone a new language when they are young and their brain is more plastic.

The Net is a Playground of Entropy
It may be fun to surf the Net and follow things randomly, but there's value in structure. The Net is a playground of entropy--the structurelessness that occurs when energy dissipates from a system. Yes, the Net also fosters self-organization, when individuals apply their energy, selectng and filtering information for others (aided by search and filtering tools). But there's rarely uch internal structure to what's selected; the structures created by links are usually webs of cross-references r...The net is information entropy in the way things are associated, without strong semantic connections, but mere relations in links.
