Logic as Magical Thinking
These battles over definition are not taking place in the same universe as the one in which men throw around these terms online. But for the Logic Guys, the purpose of using these words — the sacred, magic words like “logic,” “objectivity,” “reason,” “rationality,” “fact” — is not to invoke the actual concepts themselves. It’s more a kind of incantation, whereby declaring your argument the single “logical” and “rational” one magically makes it so — and by e...02 MAR 2019 by ideonexus
Entropy in our Everyday Lives: Active Stability
Because things naturally move to disorder over time, we can position ourselves to create stability. There are two types of stability: active and passive. Consider a ship, which, if designed well, should be able to sail through a storm without intervention. This is passive stability. A fighter jet, in contrast, requires active stability. The plane can’t fly for more than a few seconds without having to adjust its wings. This adjustment happens so fast that it’s controlled by software. Ther...27 NOV 2018 by ideonexus
Emotional Contagions in Social Networks
These results highlight several features of emotional contagion. First, because News Feed content is not “directed” toward anyone, contagion could not be just the result of some specific interaction with a happy or sad partner. Although prior research examined whether an emotion can be contracted via a direct interaction (1, 7), we show that simply failing to “overhear” a friend’s emotional expression via Facebook is enough to buffer one from its effects. Second, although nonverbal ...02 NOV 2018 by ideonexus
Input and Output Randomness
The fundamental difference between randomness that support strategy and randomness that under cuts strategy, input randomness allows the player to build the strategy output randomness undercuts it and limits your ability to plan ahead. For example let's look at Pandemic this is a great example of input randomness flicking the cards is certainly random, create a situation that the players need to react to that reaction is completely deterministic. If for example you have to roll dies if you re...Input randomness is a random initial state for a game, while output randomness is rolling dice or drawing cards during the game. The second removes strategy from the game.

The Enlightenment Needs Vigorous Defense
The ideals of the Enlightenment are products of human reason, but they always struggle with other strands of human nature: loyalty to tribe, deference to authority, magical thinking, the blaming of misfortune on evildoers. The second decade of the 21st century has seen the rise of political movements that depict their countries as being pulled into a hellish dystopia by malign factions that can be resisted only by a strong leader who wrenches the country backward to make it “great again.”...20 MAR 2018 by ideonexus
Human Females Menstruate to Eliminate Unviable Fetuses
From a female perspective, pregnancy is always a huge investment. Even more so if her species has a hemochorial placenta. Once that placenta is in place, she not only loses full control of her own hormones, she also risks hemorrhage when it comes out. So it makes sense that females want to screen embryos very, very carefully. Going through pregnancy with a weak, inviable or even sub-par fetus isn't worth it. That's where the endometrium comes in. You've probably read about how the endometriu...Folksonomies: human evolution pregnancy

The Disruptive Nature of Homo sapien's Rapid Rise to Apex...
Genus Homo’s position in the food chain was, until quite recently, solidly in the middle. For millions of years, humans hunted smaller creatures and gathered what they could, all the while being hunted by larger predators. It was only 400,000 years ago that several species of man began to hunt large game on a regular basis, and only in the last 100,000 years – with the rise of Homo sapiens – that man jumped to the top of the food chain. That spectacular leap from the middle to the top ...10 MAR 2017 by ideonexus
Changing Focus from Teacher to Learning in Education
Most theories of teaching and learning take a particular stance on the role of the teacher and the relative importance of the teaching act, in contrast to the role of the learner and the learning act. This fundamental division splits the world of educational theory into two clear schools of thought. In the first—more ancient—school, it is the authority of the teacher that takes pride of place. The teacher is seen as a master or wise one who possesses knowledge and who, through the act of ...27 DEC 2016 by ideonexus
History of the Concept of Art
Nowadays when someone speaks of "art" you probably think first of "fine arts" such as painting and sculpture, but before the twentieth century the word was generally used in quite a different sense. Since this older meaning of "art" still survives in many idioms, especially when we are contrasting art with science, I would like to spend the next few minutes talking about art in its classical sense. In medieval times, the first universities were established to teach the seven so-called "liber...15 JUN 2016 by ideonexus
