The Increasing Chemical Complexity of the Cosmos
The ancient origins of stars, planets and life may be viewed as a sequence of emergent events, each of which added to the chemical complexity of the cosmos. Stars, which formed from the primordial hydrogen of the Big Bang, underwent nucleosynthesis to produce all the elements of the Periodic Table. Those elements were dispersed during supernova events and provided the raw materials for planets and all their mineralogical diversity. Chemical evolution on Earth (and perhaps countless other plan...15 MAR 2017 by ideonexus
Emulate Water
虛實: 夫兵形象水,水之形,避高而趨下:兵之形,避實而擊虛;水因地而制流,兵因敵而制勝。故兵無常勢,水無常形;能因敵變化而取勝,謂之神。故五行無常勝,四時無常位,日有短長,月有死生。 Weak Points and Strong:...: Military tactics are like unto water; for water in its natural course runs away from high places and hastens downwards. So in war, the way is to avoid what is strong and to strike at what is weak. W...10 MAR 2017 by ideonexus
Learning is Intrinsic to Games
As one gamer has said, “In a game, you want to learn because you’re playing it, and if you didn’t want to learn, why would you be playing it?” (Selfe & Hawisher, 2007, p. 1). For this very reason, games are uniquely powerful tools that help teachers understand how to build empowering lessons and shape how students experience learning. Each game is a curriculum unto itself; each game is a unique engine that can reengineer learning experiences. Every game gives the player an opportu...Folksonomies: education gamification

The Composition of Planets
As to your reasoning of the inconvenience that a centre would become further removed from another centre than from the circumference of his own globe, though centres are of the same species while the centre and circumference are of contrary nature and should therefore be furthest removed from one another, I reply as follows: Firstly, that contraries need not be at the furthest distance one from another, inasmuch as one may influence the other or may be patient of influence therefrom; as we se...And why we do not see them orbiting other suns.

Accelerating Knowledge
The rate at which man has been storing up useful knowledge about himself and the universe has been spiraling upward for 10,000 years. The rate took a sharp upward leap with the invention of writing, but even so it remained painfully slow over centuries of time. The next great leap forward in knowledge—acquisition did not occur until the invention of movable type in the fifteenth century by Gutenberg and others. Prior to 1500, by the most optimistic estimates, Europe was producing books at a...Toffler describes and quantifies the increasing production of information in human civilization and its implications.

Combinatory Analysis in the IChing
Combinatory analysis refers to a group of techniques that can be used to determine the number of elements in a particular setwith- out having to count them one-by-one. Theelements in question could be the results froma scientific experiment or the different potential outcomes of a random event. [...] Combinatory analysis has interestedmathe- maticians forcenturies.According toTakacs (1982), such analysis dates back to ancient Greece. However, the Hindus, the Per- sians (includingthe poet an...And in another ancient Chinese text.
