 Political Detox - Why Political Discussions Become Disres...

For one week, political stories are off-topic. Please flag them. Please also flag political threads on non-political stories. For our part, we'll kill such stories and threads when we see them. Then we'll watch together to see what happens. Why? Political conflicts cause harm here. The values of Hacker News are intellectual curiosity and thoughtful conversation. Those things are lost when political emotions seize control. Our values are fragile—they're like plants that get forgotten, then ...

 How to Teach Vocabulary

Begin with a story or explanation of the term. Modeling how you use the word in your life or in conversation may be helpful to students. Have students put information into their own words. This process, which I call “recoding,” is necessary to make sure students understand the word. This is a vital step in the memory process. Skipping this step can be disastrous as students may have a misconception that will be placed in long-term memory through incorrect rehearsals (Sprenger, 2005). Ask ...

 Five Ways to Stretch Your Perception of Time

1. Keep learning Learning new things is a pretty obvious way to pass your brain new information on a regular basis. If you’re constantly reading, trying new activities or taking courses to learn new skills, you’ll have a wealth of ‘newness’ at your fingertips to help you slow down time. 2.

 The Concept of Supervenience and the Web

One view is reminiscent of the philosophical idea of supervenience [168, 169]). One discourse or set of expressions A supervenes on another set B when a change in A entails a change in B but not vice versa. So, on a supervenience theory of the mind/brain, any change in mental state entails some change in brain state, but a change in brain state need not necessarily result in a change in mental state. Supervenience is a less strong concept than reduction (a reductionist theory of the mind/brai...
