What science actually does is to show that any natural object we please may be treated in terms of relations upon which its occurrence depends, or as an event, and that by so treating it we are enabled to get behind, as it were, the immediate qualities the object of direct experience presents, and to regulate their…
When I realized that I was unintentionally disengaging from some students, I developed a classroom management practice that ensures equal participation and on-the-fly formative assessments. I use a deck of playing cards, each of which is marked with a student's name, to determine who will answer the next question. The…
...innovation often occurs through sequencing—building on prior innovation. Recall that suitcases didn't used to have wheels. Then someone created a suitcase with two wheels. Now many suitcases have four wheels. What helpful improvement on the suitcase might come next? I've pitched this question to students, who then…
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…
What is This? My Example urlHosted is an experimental web app that misuses the part after the "#" of a URL to store and read data. The app is unhosted. See this definition from unhosted.org: Also known as "serverless", "client-side", or "static" web apps, unhosted web apps do not send your user data to their server…
Kindergarten means a garden of children, and Froebel, the inventor of it, or rather, as he would prefer to express it, the discoverer of the method of Nature, meant to symbolize by the name the spirit and plan of treatment. How does the gardener treat his plants? He studies their individual natures, and puts them into…
None of this actually explains how Flatlanders move. We know various things about their locomotion; that travelling somewhere involves some form of effort, that it is harder to travel North than in other directions, especially for women, and that femails "undulate" as they travel, although this is more of a safety…
So did Hobbes get it right? In part, he did. In the nature of man we find three principal causes of quarrel: gain (predatory raids), safety (preemptive raids), and reputation (retaliatory raids). And the numbers confirm that relatively speaking, “during the time men live without a common power to keep them all in awe…
In communication theory, information is the reduction of prior uncertainty. Organisms are 'uncertain' because they are composed of conditional adaptations that adopt different states under different conditions. These mechanisms can be described in terms of the decision rules that they embody—'if A, then B', or 'If you…
Filters in a digital world work not by removing what is filtered out; they simply don't select for it. The unselected material is still there, ready to be let through by someone else's filter. Intelligent filters, which is what we need, come in three kinds: A smart person who takes in a lot and tells you what you need…
A child stacks and packs all kinds of blocks and boxes, lines them up, and knocks them down. What is that all about? Clearly, the child is learning about space! But how on earth does one learn about time? Can one time fit inside another? Can two of them go side by side? In music, we find out! It is often said that…
The research looked at the results of an experiment in which 282 participants in grades 2-4 were observed in the fall and spring during one school year. Student engagement was monitored by actions such as answering a question, raising a hand, or participating in discussion, while off-task behaviors included talking…
When Mike was installed in Luna, he was pure thinkum, a flexible logic--"High-Optional, Logical, Multi-Evaluating Supervisor, Mark IV, Mod. L"--a HOLMES FOUR. He computed ballistics for pilotless freighters and controlled their catapult. This kept him busy less than one percent of time and Luna Authority never…
In the Wonderland of these statistics, a remarkable number of law school grads are not just busy — they are raking it in. Many schools, even those that have failed to break into the U.S. News top 40, state that the median starting salary of graduates in the private sector is $160,000. That seems highly unlikely, given…
The whole world needs to burn coal and oil, right? So what’s wrong with our coal? Do you know how much coal China has burned? In 2013, we had already burned 3.6 billion tons. But do you know how much all the other countries in the world have burned? We have burned more coal than the rest of the world combined. The…
Look at them, the bugs. Humans have used everything in their power to extinguish them: every kind of poison, aerial sprays, introducing and cultivating their natural predators, searching for and destroying their eggs, using genetic modification to sterilize them, burning with fire, drowning with water. Every family…
At least once a week, if not once a day, we might each ponder what cosmic truths lie undiscovered before us, perhaps awaiting the arrival of a clever thinker, an ingenious experiment, or an innovative space mission to reveal them. We might further ponder how those discoveries may one day transform life on Earth…
What follows herein is strictly for the eyes of you, the campaign referee. As the creator and ultimate authority in your respective game, this work is written as one Dungeon Master equal to another. Pronouncements there may be, but they are not from "on high" as respects your game. Dictums are given for the sake of…
1. First, you start with soil. We identify what nutrition the soil lacks. 2. Then we identify what species we should be growing in this soil, depending on climate. 3. We then identify locally abundant biomass available in that region to give the soil whatever nourishment it needs. This is typically an agricultural or…
...like curriculum, the garden is primarily a social construct that reflects the intent of the maker and the prevailing cultural ideologies of the time. The lived experiences of the person within both curriculum and garden are a synthesis of orchestrated and phenomenological experiences. The garden and the curriculum…
