 Border Crossings into Science Culture

Learning to communicate in and with a culture of science is a much broader undertaking than mastering a body of discrete conceptual or procedural knowledge. One observer, for example, describes the process of science education as one in which learners must engage in "border crossings" from their own everyday world culture into the subculture of science.^ The subculture of science is in part distinct from other cultural activities and in part a reflection of the cultural backgrounds of scienti...

 Animism, Solipsism, Language

Animism—the belief in n an intiterior spiritual reality to all things—sounds, to late twentieth-century eaars, quite a bi bit like solipsism, which holds that t only the self exists, manifesting itself in the architecture of reality. The "reality" of cyberspace falls somewhere in betwween these two; everything has an interior nature, which generates meaning, but this interior nature is self-created; collective will creating consensual reality. Appropriaately, there is precedent for this c...

 Games Use Constant Feedback

Moreover, games use systems of points, scores, leaderboards, achievement walls, and other clever mechanisms to reinforce how well you are playing (or not playing). Feedback should force us to face reality and redirect our efforts where they are needed. Regular, systemic feedback is a rarity in the traditional school; it is, however, de rigueur in even the most poorly designed game. It is this regular, rapid feedback that not only stimulates persistence and self-direction but also gets people ...

 The Machine Euthanizes the Atheletic

"Well, the Book"s wrong, for I have been out on my feet." For Kuno was possessed of a certain physical strength. By these days it was a demerit to be muscular. Each infant was examined at birth, and all who promised undue strength were destroyed. Humanitarians may protest, but it would have been no true kindness to let an athlete live; he would never have been happy in that state of life to which the Machine had called him; he would have yearned for trees to climb, rivers to bathe in, meado...

 Theoretical Uncertainty has No Meaning

If one looks at the history of knowledge, it is plain that at the beginning men tried to know because they had to do so in order to live. In the absence of that organic guidance given by their structure to other animals, man had to find out what he was about, and he could find out only by studying the environment which constituted the means, obstacles and results of his behavior. The desire for intellectual or cognitive understanding had no meaning except as a means of obtaining greater secur...

 Believing in the Afterlife Belittles the Importance of a ...

When my husband died, because he was so famous and known for not being a believer, many people would come up to me-it still sometimes happens-and ask me if Carl changed at the end and converted to a belief in an afterlife. They also frequently ask me if I think I will see him again. Carl faced his death with unflagging courage and never sought refuge in illusions. The tragedy was that we knew we would never see each other again. I don't ever expect to be reunited with Carl. But, the great thi...

 Infinity Times Zero is Not Zero

The problem is that the laws of addition and multiplication you are using hold for natural numbers, but infinity is not a natural number, so these laws do not apply. If they did, you could use a similar argument that multiplying anything by infinity, no matter how small, gives infinity, thus ∞×0=∞. More sophisticated arguments can also be made, like ∞×0=limx→∞(x×1/x)=1. Clearly all these different values for ∞×0 mean that ∞ cannot be treated like other numbers. In order to ...

 "Infinite in All Directions," Meaning of the Title

The title is now changed so as to focus more sharply upon the message I am preaching. Boiled down to one sentence, my message is the unbounded prodigality of life and the consequent unboundedness of human destiny. As a working hypothesis to explain the riddle of our existence, I propose that our universe is the most interesting of all possible universes, and our fate as human beings is to make it so.

 Giordano Bruno Observations of the Sun

The meaning is the more excellence, as it is the less vulgar, and you will see that it is single, unified, and not strained. You must consider that although the sun appears different with respect to different regions of the earth according to time and place, nevertheless with respect to the entire globe it acts always and everywhere in the same way, for in whatever point of the ecliptic it may find itself, it causes winter, summer, autumn, and spring, and the entire earthly globe receives the...
