 Why Correlate IQ and Race?

...the question of the relation, if any, between race and intelligence has very little scientific importance (as it has no social importance, except under the assumptions of a racist society) … As to social importance, a correlation between race and mean I.Q. (were this shown to exist) entails no social consequences except in a racist society in which each individual is assigned to a racial category and dealt with not as an individual in his own right, but as a representative of this catego...

 Tenets of the Satanic Temple

There are seven fundamental tenets. One should strive to act with compassion and empathy towards all creatures in accordance with reason. The struggle for justice is an ongoing and necessary pursuit that should prevail over laws and institutions. One’s body is inviolable, subject to one’s own will alone. The freedoms of others should be respected, including the freedom to offend. To willfully and unjustly encroach upon the freedoms of another is to forgo your own. Beliefs should conform...

 The Problem with How We Teach Math

Why do some children find Math hard to learn?  I suspect that this is often caused by starting with the practice and drill of a bunch of skills called Arithmetic—and instead of promoting inventiveness, we focus on preventing mistakes.  I suspect that this negative emphasis leads many children not only to dislike Arithmetic, but also later to become averse to everything else that smells of technology. It might even lead to a long-term distaste for the use of symbolic representations. ...

 The Problem with Age-Segregation in Schools

A new class of 6-year-old children will soon begin to share similar ways to think and behave. Then, next year, when they are 7 years old, most of those pupils will still remain in that group—and thus will tend to perpetuate those same patterns of activity. The next year, they will be 8-year-olds, but will continue to share many attitudes, values, and cognitive strategies. So as those children proceed through their K-12 grades, large portions of their ways to think will remain much like th...

 Ways to Tackle a Problem

If a problem seems familiar, try reasoning by Analogy.  If you solved a similar one in the past, and can adapt to thedifferences, you may be able to re-use that solution.  If the problem still seems too hard, divide it into several parts.  Every difference you recognize may suggest a separate subproblem to solve. If it seems unfamiliar, change how you’re describing it. Find a different description that highlights more relevant information. If you get too many ideas, then focus on ...

 The Stress of Cold Temperatures Extends Lifespans

In 1986, John Holloszy of Washington University immersed his lab rats in shallow, cool water for four hours each day. They burned so many extra calories that they ate half again as much as control rats, but weighed less. The cold rats lived 10% longer, on average. Holloszy framed his report on this experiment not as a hormetic effect of cold exposure, but as a refutation of the “rate of living” hypothesis. In 2006, Gordon Lithgow of the Buck Institute for Aging Research exposed lab worms...

 12 Tone Equal Temperament

On a standard piano keyboard, one octave is divided into 7 whole tones: A, B, C, D, E, F and G. In between these tones are 5 further notes which can be called either sharps or flats: A# (Bb), C# (Db), D# (Eb), F# (Gb), G# (Ab). (whether it's a sharp of a flat doesn't really matter, the note has the same frequency, just a different name). This gives us a grand total of 12 notes in one octave. If you were to measure the frequency of a note, then measure the frequency of a note exactly one octa...

 The Mind on Music

For some reason that no one really understands, there is a psychological effect upon human listeners in regards to the musical scale. The tonic pitch, or tonal center is not only the mathematical center of the scale, but is the psychological center as well. Human perception of the tonic pitch in relation to the other notes of the scale gives each note of the scale, including the tonic pitch, a distinct "personality" or identity. If we were to label each note of the major scale with a number, ...

 Idea Debt

Idea Debt is when you spend too much time picturing what a project is going to be like, too much time thinking about how awesome it will be to have this thing done and in the world, too much time imagining how cool you will look, how in demand you’ll be, how much money you’ll make. And way too little time actually making the thing. If… You tell 15 friends about your screenplay idea, but devote zero time in your week to facing the blank screen. You buy a domain name, spend weeks or mont...

 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....
