The Effort in Keeping the Internet Clean

Contract workers in San Francisco, processing thousands of complaints a day. Sweatshops in the Philippines, where outsourced labor decides what’s obscene and what’s permissible in a matter of seconds. Teams of anti-spam engineers in Mountain View, adapting to the latest wave of bots. An unpaid moderator on Reddit, picking out submissions that violate guidelines. So much of the internet is garbage, and much of its infrastructure and many work hours are devoted to taking out the garbage. F...

 Being Against Technological Progress if Futile

Ron complaining that antibiotics put too many grave diggers out of work. The transfer of labor from humans to our inventions is nothing less than the history of civilization. It is inseparable from centuries of rising living standards and improvements in human rights. What a luxury to sit in a climate-controlled room with access to the sum of hu¬ man knowledge on a device in your pocket and lament how we don't work with our hands anymore! There are still plenty of places in the world where p...

 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...

 The Dojo Extends Beyond its Walls

If the translation of Do predicates the meaning of one's Truth, what we call home for the purpose of such training is Dojo. Jo (translated as the place, or the Hall) is the center of total focus, where all venerable learning is to take place through myriads of human struggles and energetic interactions. It is therefore stated cogently that the place called "Dojo" must be designated as the place of being enlightened by all things. It is the place where one's purest form of existence must be fo...

 Civilization is About Capturing Energy

Civilisation, like life itself, has always been about capturing energy. That is to say, just as a successful species is one that converts the sun’s energy into offspring more rapidly than another species, so the same is true of a nation. Progressively, as the aeons passed, life as a whole has grown gradually more and more efficient at doing this, at locally cheating the second law of thermodynamics. The plants and animals that dominate the earth today channel more of the sun’s energy thro...

 All War is Based on Deception

兵者，詭道也。故能而示之不能，用而示之不用，近而示之遠，遠而示之近。利而誘之，亂而取之，實而備之，強而避之，怒而撓之，卑而驕之，佚而勞之，親而離之。攻其無備，出其不意，此兵家之勝，不可先傳也。 All warfare is based on deception. Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away;when far awa...

 Unlike Physics, Biology Can't Ignore Information

Physicists love to think about systems that take only a little information to describe. So when they get a system that takes a lot of information to describe, they use a trick called 'statistical mechanics', where you try to ignore most of this information and focus on a few especially important variables. For example, if you hand a physicist a box of gas, they'll try to avoid thinking about the state of each atom, and instead focus on a few macroscopic quantities like the volume and total en...

 Teaching Temperature

Outside Temperatures. Place a thermometer outside a window so students can make daily calculations and keep a chart reporting the actual temperature and the temperature change from the previous day. Students will see that the change can be a negative number without the temperature falling below 0—an often-confusing concept that is clarified by these observations. An achievable-challenge extension could include barometers, and students who need more advanced work can learn how negative—or...
