 A Sick Burn

Yet your prison without coherent design continues to imprison you. How can this be, if it has no strong places? The rational prisoner exploits the weak places, creates order from chaos: instead, collectives like the FSF vindicate their jailers by building cells almost compatible with the existing ones, albeit with more features. The journalist with three undergraduate degrees from MIT, the researcher at Microsoft, and the senior scientist at Apple might volunteer a few words about the regulat...

 Roman Arithmetic

...basic Roman arithmetic is largely rather simple, even for those of us spoiled by Arabic notation. Addition is no sweat, because complex Roman numbers already use what math pros call additive notation, with numerals set beside one another to create a larger number. VI is just V plus I, after all. To add large numbers, simply pile all the letters together, arrange them in descending order, and there’s your sum. CLXVI plus CLXVI? CCLLXXVVII, or CCCXXXII. And one of the advantages of the Rom...

 How the fantastic becomes dull and familiar

Most fantasy RPGs follow the tried and allegedly true formula, which strips them of anything ‘fantastic’ and grounds them in the dull ‘reality’ of the familiar. Sadly, the much coveted instant recognition usually means instantly forgettable. How many times should we save an utterly predictable and generic world before it gets really old? Why is that when we see a town on the horizon, it’s not a place of wonder and strange customs, but a place to restock on FEDEX quest and trade in y...

 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...

 Ideal Amount of Exercise for Longevity

People who got some exercise, but not enough to meet the physical activity recommendations were still 20 percent less likely to die over a 14-year period than those who did not do any physical activity. (The recommendations say to do 150 minutes of moderate activity per week or 75 minutes of vigorous activity per week.) People who engaged in the recommended level of physical activity saw even more benefit: They were 31 percent less likely to die during the study period, compared with those w...

Who recommendation is 150 minutes moderate or 75 minutes vigorous a week. Three to five times this amount was linked with a 39% reduction in mortality; therefore, 7.5 hours moderate exercise or 3.75 hours vigorous for best results.

 Mindfulness to Teach Students How to Pay Attention

"One of the primary ironies of modern education is that we ask students to 'pay attention' dozens of times a day, yet we never teach them how," Amy Saltzman elucidates in PBS's Mindfulness: A Teacher's Guide. "The practice of mindfulness teaches students how to pay attention, and this way of paying attention enhances both academic and social-emotional learning." [...] Mindful Schools recommends starting with a simple practice like mindful listening, where students sit in silence and notice ...

 Centireading: Reading a Book 100 Times

After a hundred reads, familiarity with the text verges on memorisation – the sensation of the words passing over the eyes like cud through the fourth stomach of a cow. Centireading belongs to the extreme of reader experience, the ultramarathon of the bookish, but it’s not that uncommon. To a certain type of reader, exposure at the right moment to Anne of Green Gables or Pride and Prejudice or Sherlock Holmes or Dune can almost guarantee centireading. Christmas is devoted to reading books...

 Lojban as AI Language

Can machines feel pride? Not sure question means anything. But you've seen dogs with hurt feelings and Mike had several times as complex a neural network as a dog. What had made him unwilling to talk to other humans (except strictly business) was that he had been rebuffed: They had not talked to him. Programs, yes--Mike could be programmed from several locations but programs were typed in, usually, in Loglan. Loglan is fine for syllogism, circuitry, and mathematical calculations, but lacks fl...

 We are the Dreams of a Future AI

An evolving cyberspace becomes effectively ever more capacious and long lasting, and so can support ever more minds of ever greater power. If these minds spend only an infinitesimal fraction of their energy contemplating the human past, their sheer power should ensure that eventually our entire history is replayed many times in many places, and in many variations. The very moment we are now experiencing may actually be (almost certainly is) such a distributed mental event, and most likely is ...

 The Umwelt Bubble

The biologist Jakob von Uexküll’s term Umwelt refers to a concept about the subjective world of an organism. The world can be imagined as a soap bubble, which surrounds each individual and contains signifying markers relevant only to the world of that specific creature. This soap bubble, or Umwelt, is actively created by the individual organism in a process of forming a perception of reality, which is guided by the organism’s design, its physiology, and its needs. According to Uexküll,...
