## Level Two Chaos

Level two chaos is chaos that reacts to predictions about it, and therefore can never be predicted accurately. Markets, for example, are a level two chaotic system. What will happen if we develop a computer program that forecasts with 100 per cent accuracy the price of oil tomorrow? The price of oil will immediately react to the forecast, which would consequently fail to materialise. If the current price of oil is \$90 a barrel, and the infallible computer program predicts that tomorrow it wil...

## Cooperative Game of Competitive Questioning

Great Cooperative games make the play experience deliberately difficult; the game shouldn't be a cake walk. Mr. Glass's decision, therefore, is for him to assume the role of the game and present himself in opposition to his students—the players. He does this by instructing his students (working in groups designed to get everyone working together, especially those who have struggled in the past) to prepare 30 questions that, in their estimation, adequately assess or measure the topics with w...

## Digital Content and the Common Core

Common Core Standard 7 says students should be able to "integrate and evaluate content presented in diverse media and formats, including visually and quantitatively, as well as in words." Anchor Standard 6 in writing says students should "use technology, including the internet, to produce and publish writing and to interact and collaborate with others." And Anchor Standard 8 says students should "gather relevant information from multiple print and digital sources, assess the credibility and ...

## Language is Important in Direction

The room is made i.^ up of four curtains, used to create four walls in a rectangle, defined by two types of information: geometric (two short walls and two long walls) and color information (one red wall). Now, think about the corners. If you are using only geometric information, pairs of corners are identical. There are two corners with a short wall on the ft and a long wall on the right, and two corners the other way around. If you are using only color information, there are also two pair...

## Overconfidence Breeds Error

In one classic demonstration, clinical psychologists were asked to give confidence judgments on a personality profile. They were given a case report in four parts, based on an actual clinical case, and asked after each part to answer a series of questions about the patient’s personality, such as his behavioral patterns, interests, and typical reactions to life events. They were also asked to rate their confidence in their responses. With each section, background information about the case i...

## Physics VS Metaphysics

In the 1920s, there was a dinner at which the physicist Robert W. Wood was asked to respond to a toast ... "To physics and metaphysics." Now by metaphysics was meant something like philosophy—truths that you could get to just by thinking about them. Wood took a second, glanced about him, and answered along these lines: The physicist has an idea, he said. The more he thinks it through, the more sense it makes to him. He goes to the scientific literature, and the more he reads, the more promi...

## The Universe is One Great Machine

Look round the world, contemplate the whole and every part of it: you will find it to be nothing but one great machine, subdivided into an infinite number of lesser machines, which again admit of subdivisions to a degree beyond what human senses and faculties can trace and explain. All these various machines, and even their most minute parts, are adjusted to each other with an accuracy which ravishes into admiration all men who have ever contemplated them. The curious adapting of means to end...

## Knowledge Must be Combined With Honesty

Knowledge and ability must be combined with ambition as well as with a sense of honesty and a severe conscience. Every analyst occasionally has doubts about the accuracy of his results, and also there are times when he knows his results to be incorrect. Sometimes a few drops of the solution were spilt, or some other slight mistake made. In these cases it requires a strong conscience to repeat the analysis and to make a rough estimate of the loss or apply a correction. Anyone not having suffic...

## The Political Environmental Conundrum

Action regarding the environment requires objectivity, precision, accuracy, validity, replication, constructive criticism, and consensus. Scientists, engineers, and economists have to stay focused on putting accurate data into the hands of decision makers, while they explain their findings to the public, which, in the end, wields decisive power in a free society. Mechanisms must be developed to transform highly technical findings into governmental and economic policies. If we can reach a po...

## Dunning–Kruger effect

People tend to hold overly favorable views of their abilities in many social and intellectual domains. The authors suggest that this overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it. Across 4 studies, the authors found that participants scoring in the bottom quartile on tests of hum...
