Anthropocene Traps
The concept of evolutionary traps has been used almost exclusively for studying how non-human species respond to cues in anthropogenic environments [24–34]. Key examples include artificial human lights attracting insects, island species responding naively to the presence of introduced predators, and seabirds not being able to discriminate between the cues of marine plankton and marine plastics [34–36] (figure 1a). In the context of humans, evolutionary mismatch is a much more frequently u...Folksonomies: evolution maladaptation

Understanding Cause and Effect is Based on Experience
Were a man, such as Adam, created in the full vigor of understanding, without experience, he would never be able to infer motion in the second ball from the motion and impulse of the first. It is not anything that reason sees in the cause, which make us infer the effect. Such an inference, were it possible, would amount to a demonstration, as being founded merely on the comparison of ideas. But no inference from cause to effect amounts to a demonstration, as being founded merely on the compar...Folksonomies: philosophy empiricism

Space Colonists as Selfish Fools
Human beings live in ideas. That they were condemning their descendants to death and extinction did not occur to them, or if it did they repressed the thought, ignored it, and forged on anyway. They did not care as much about their descendants as they did about their ideas, their enthusiasms. Is this narcissism? Solipsism? Idiocy (from the Greek word idios, for self)? Would Turing acknowledge it as proof of human behavior? Well, perhaps. They drove Turing to suicide too. No. No. It was not...Told from the perspective of the AI running the ship.

Scientific Laws Mean That God has No Freedom
he one remaining area that reHgion can now lay claim to is the origin of the universe, but even here science is making progress and should soon provide a definitive answer to how the universe began. I published a book that asked if God created the universe, and that caused something of a stir. People got upset that a scientist should have anything to say on the matter of religion. I have no desire to tell anyone what to believe, but for me asking if God exists is a valid question for science...02 MAR 2019 by ideonexus
New Kind of Memory for AI
AI researchers have typically tried to get around the issues posed by by Montezuma’s Revenge and Pitfall! by instructing reinforcement-learning algorithms to explore randomly at times, while adding rewards for exploration—what’s known as “intrinsic motivation.” But the Uber researchers believe this fails to capture an important aspect of human curiosity. “We hypothesize that a major weakness of current intrinsic motivation algorithms is detachment,” they write. “Wherein the algorithms forget...31 OCT 2018 by ideonexus
Bumper Sticker Computer Science
A few of my favorites, not found in the linked article: "There are two ways of constructing software. One way is to make it so simple that there are obviously no deficiencies. The other is to make it so complex that there are no obvious deficiencies." C.A.R. Hoare "The purpose of software engineering is to control complexity, not to create it." Dr. Pamela Zave "The most important single aspect of software development is to be clear about what you are trying to build." Bjarne Stroustrup "T...27 JUL 2018 by ideonexus
With Educational Games, Even if the Kids Don't Get It, Yo...
...where does probability theory come from? What is its source? Clearly, like many other sciences, like arithmetic itself, probability theory emerged from observations of certain real-world phenomena, namely, random, unpredictable phenomena. And it is exactly these kinds of observations—fundamental to the formation of science—which are worth making together with kids. Well, not all of them, of course, just the simplest ones. Besides, kids are making them on their own; e.g., when they play gam...27 JUL 2018 by ideonexus
Our Modern Worldview and Morality is Shaped by Science
To begin with, the findings of science imply that the belief systems of all the world’s traditional religions and cultures—their theories of the genesis of the world, life, humans, and societies—are factually mistaken. We know, but our ancestors did not, that humans belong to a single species of African primate that developed agriculture, government, and writing late in its history. We know that our species is a tiny twig of a genealogical tree that embraces all living things and that emerged...16 APR 2018 by ideonexus
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
