Space is Negative Energy
The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materiahse out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy."
To help you get your head around this weird'd but crucial concept, let me draw on a simple analogy Imagine a man wants to build a hill on a flat piece of land. The hill will represent the univ... 1

Seeing Organizations as Biological Systems
There’s a continuing struggle between complexity and robustness in both evolution and human design. A kind of survival imperative, whether in biology, engineering, or business requires that simple, fragile systems become more robust. But the mechanisms to increase robustness will in turn make the system considerably more complex. Furthermore, that additional complexity brings with it its own unanticipated failure modes, which are corrected over time with additional robust mechanisms, which ... 1 notes

“Judge the value of what you have by what you had to gi...
The principle of an opportunity cost does not at first glance seem hard to understand. If you spend half an hour noodling around on Twitter, when you would otherwise have been reading a book, the lost book-reading time is the opportunity cost of the tweeting. If you decide to buy a fancy belt for £100 instead of a cheaper one for £20, the opportunity cost is the £80 shirt you could otherwise have bought. Everything has a cost: whatever you were going to do instead, but couldn’t.

A Student's Skill-Level Should be Private
A student's skill level should be a private matter, between him and the teacher, and students who are behind should be able to work comfortably, without embarrassment. "They know they should know more. They know they should not be working on tens and ones when their friends are doing division and fractions and all that, and there's no shame in working on it with the computer." Actually, the same principle applies to kids who are off-the-charts advanced: if they just want to relax and do high-...Folksonomies: education personalization

Anarchism Extends from Socialism
Rudolf Rocker describes modern anarchism as “the confluence of the two great currents which during and since the French revolution have found such characteristic expression in the intellectual life of Europe: Socialism and Liberalism.” The classical liberal ideals, he argues, were wrecked on the realities of capitalist economic forms. Anarchism is necessarily anticapitalist in that it “opposes the exploitation of man by man.” But anarchism also opposes “the dominion of man over man.... 1 notes

The Give-N Task for Assessing Child Number Knowledge
Children learn very early (often as young as 2 years old) to
recite the number-word list in order (Fuson, 1988). But at
the beginning, the words are merely placeholders—children
recite the list without knowing what the individual number
words mean. Over time, children fill in the words with
meaning, one at a time and in order (Carey, 2009; Sarnecka
& Lee, 2009). The child’s progress on this front is called
their number-knower level, or just knower level. A child
who does not yet know ...Folksonomies: education mathematics

Principles of Transhumanism and Conflict
All transhumanists to date would likely also have no disagreement with the principles of intelligent technology, self-direction, or rational thinking. Intelligent Technology “means designing and managing technologies not as ends in themselves but as effective means for improving life. Applying science and technology creatively and courageously to transcend ‘natural’ but harmful, confining qualities derived from our biological heritage, culture, and environment.” Self-direction means ...Folksonomies: philosophy transhumanism

Anyone Should be Allowed to Speak
Anyone should be allowed to speak out, whoever he may be, so long as he is not a hostile element and does not make malicious attacks, and it does not matter if he says something wrong. Leaders at all levels have the duty to listen to others. Two principles must be observed: (1) Say all you know and say it without reserve; (2) Don't blame the speaker but take his words as a warning. Unless the principle of "Don't blame the speaker" is observed genuinely and not falsely, the result will not be ... 1 notes

Objective in the "Real Life" Game
The game heavily relies on the "carrot on a stick" principle. All objectives appear to be increasingly possible, yet every goal point disappears moments before you achieve it. There also appears to be no reward for honesty, hard work, altruism, or loyalty.
Highly pessimistic version.

Enthusiasm Improves Productivity
When we are engaged in what we are
doing, all sorts of things happen. We
persist longer at difficult problems—and
become more likely to solve them. We
experience something that psychologist
Tory Higgins refers to as flow, a presence
of mind that not only allows us to extract
more from whatever it is we are doing but
also makes us feel better and happier: we
derive actual, measurable hedonic value
from the strength of our active
involvement in and attention to an activity,
even if the activi...
1 And it creates a cycle of enthusiasm as our accomplishments increase our positive outlook on the task, increasing our focus.
