Gamification Set Collection
I recently codeveloped a game with a colleague who teaches a course in global studies to advanced high school students. We called the game Global Shuffle, and it was meant to simulate two realities of the 21st century global marketplace. First, the developed world creates certain kinds of resources, and the developing world creates different resources. Though this is true, these resources relate to each other and have a reflexive quality; resources that are available or made in the developed ...Folksonomies: education gamification

The Monte Carlo Method and Evolutionary Algorithms
Back then, I thought of one thing: Have you heard of the Monte Carlo method? Ah, it’s a computer algorithm often used for calculating the area of irregular shapes. Specifically, the software puts the figure of interest in a figure of known area, such as a circle, and randomly strikes it with many tiny balls, never targeting the same spot twice. After a large number of balls, the proportion of balls that fall within the irregular shape compared to the total number of balls used to hit the ci...Folksonomies: algorithms evolutionary algorithms

Computer Metaphors for Biochemistry
The metaphor of the computer represents in some crude fashion the chemistry of life. Nowadays one may assume that the average citizen of an industrialized country is at least as familiar with computers as with rain forests. The idea of using the computer as a metaphor is a natural one. A computer is a device for handling information according to a program which it is able to remember and execute. A living cell, to remain in control of its vital functions in a variable environment, must also p...Folksonomies: metaphors

Hydrogen Levels in the Universe
Our Sun is significantly enriched, having formed when the Universe was more than 9 billion years old in the plane of a spiral galaxy, one of the most enriched places in the Universe. Yet, when our Sun formed, it was still made out of — by mass — 71% hydrogen, 27% helium, and about 2% “other” stuff. If we convert that into “number of atoms” and treat the Sun as typical of the Universe, that means, over the first 9.3 billion years of the Universe, the fraction of hydrogen ha... 1 notes

Spider Trap
A spider trap (or crawler trap) is a set of web pages that may intentionally or unintentionally be used to cause a web crawler or search bot to make an infinite number of requests or cause a poorly constructed crawler to crash. Web crawlers are also called web spiders, from which the name is derived. Spider traps may be created to "catch" spambots or other crawlers that waste a website's bandwidth. They may also be created unintentionally by calendars that use dynamic pages with l...Folksonomies: computer science hacking

IDIC - Infinite Diversity in Infinite Combinations
IDIC basically states that we should delight in the differences amongst people, not hate people because they are different. It seems that the human race has found a large number of ways to hate (different sex, color, religion, nationality, political party, social class, etc) and has emphasized hate over co-operation, caring, and compassion. The result has been a world torn by big and small wars, religious and philosophical differences, and alienation of one person from another.
This has take...

The Link Between Smoking and Cancer
The risk of developing carcinoma of the lung increases steadily as the amount smoked increases. If the risk among non-smokers is taken as unity and the resulting ratios in the three age groups in which a large number of patients were interviewed (ages 45 to 74) are averaged, the relative risks become 6, 19, 26, 49, and 65 when the number of cigarettes smoked a day are 3, 10, 20, 35, and, say, 60—that is, the mid-points of each smoking group. In other words, on the admittedly speculative ass... 1 notes

Repeatability and Probability
When an observation is made on any atomic system that has been prepared in a given way and is thus in a given state, the result will not in general be determinate, i.e. if the experiment is repeated several times under identical conditions several different results may be obtained. If the experiment is repeated a large number of times it will be found that each particular result will be obtained a definite fraction of the total number of times, so that one can say there is a definite probabil...Folksonomies: experimentation

Disproving Santa Claus with a Back of the Napkin Calculation
There is another approach to the extraterrestrial hypothesis of UFO origins.
This assessment depends on a large number of factors about which we know little,
and a few about which we know literally nothing. I want to make some crude
numerical estimate of the probability that we are frequently visited by
extraterrestrial beings.
Now, there is a range of hypotheses that can be examined in such a way. Let
me give a simple example: Consider the Santa Claus hypothesis, which maintains
that, in a ...

Homogenization of the Milky Way
It is possible to speculate on the very distant future of advanced civilizations. We
can imagine such societies in excellent harmony with their environments, their
biology, and the vagaries of their politics, so that they enjoy extraordinarily long
lifetimes. Communications would long have been established with many other
such civilizations. The diffusion of knowledge, techniques, and points of view
would occur at the velocity of light. In time, the diverse cultures of the Galaxy,
involving a...Folksonomies: culture homogenization
