 Programming as a Way of Thinking

Running programs is the whole point of programming, of course, but there is more to it. The ability to execute code makes programming a tool for thinking and exploring. When we express ideas as programs, we make them testable; when we debug programs, we are also debugging our brains.

 What We Learn from Games

What also went unremarked was how much I was learning by playing these games: basic ideas such as taking turns and developing patience while others completed their turns, the strengthening of simple memory, improved physical coordination, an ability to recognize and act on patterns, the capacity to see what might happen in a few turns if I took one move as opposed to another, resilience when losing, and the kind of strategic thinking that emerges once you realize that Scrabble is both a game ...

 You were never actually accomplishing anything by watchin...

If you ask someone what they accomplish by watching the news, you’ll hear vague notions like, “It’s our civic duty to stay informed!” or “I need to know what’s going on in the world,” or “We can’t just ignore these issues,” none of which answer the question. “Being informed” sounds like an accomplishment, but it implies that any information will do. You can become informed by reading a bus schedule. A month after you’ve quit the news, it’s hard to name anything u...

 Core Elements of Reading Skills

In 2008, the National Institute of Literacy issued its report, Developing Early Literacy: Report of the National Early Literacy Panel, and, among its many findings, stated that the foundational reading and writing skills that develop from birth to age five have a clear and consistently strong relationship with later conventional literacy skills. “These six variables not only correlated with later literacy as shown by data drawn from multiple studies with large numbers of children, but also ...

 Physiological Decline in the Body When You Stop Exercising

...regular endurance exercise leads to four major consequences: Increased ability of the heart to eject blood increased ability of the blood vessels to send blood to where blood is needed Increased number of capillaries (the vessels that deliver oxygen and ‘food’ to the muscles) increased size and the number of mitochondria (the “power plants” of the cells). All these changes lead to the more efficient use of oxygen, as well as nutrients. [...] Pino considers a person who can run...

 The Republican Party needs to stop talking to itself

The Republican Party needs to stop talking to itself. We have become expert in how to provide ideological reinforcement to like-minded people, but devastatingly we have lost the ability to be persuasive with, or welcoming to, those who do not agree with us on every issue.

 Apple is Not the Alternative Choice

For some reason Apple is still considered the liberal/counter-cultural choice but if you think about every dystopian novel/movie and then I said “there’s going to be a company, the world’s largest company (or thereabouts), they’re going to sell one product (basically - the difference between an iphone/ipad/macbook/apple watch is just the form factor) that everyone has to accept as is, and people will line up for days for that one product, missing work to get it, you will have no contr...

 Sugar Impacts Learning

The DHA-deprived rats also developed signs of resistance to insulin, a hormone that controls blood sugar and regulates synaptic function in the brain. A closer look at the rats' brain tissue suggested that insulin had lost much of its power to influence the brain cells. "Because insulin can penetrate the blood–brain barrier, the hormone may signal neurons to trigger reactions that disrupt learning and cause memory loss," Gomez-Pinilla said. He suspects that fructose is the culprit behi...

 Hyperlinks as Conversation

Hyperlinks are fine-grained, bidirectional, and extrinsic. Frequently, an argument is not with a document or chapter as a whole. It is with a particular point that someone made at a particular place in the text. For example, someone refers to the fourth law of thermodynamics, and someone else writes a criticism saying there is no fourth law of thermodynamics, linking it to the original. The fine-grained property allows the link to designate the particular piece of text with which one is takin...

 Debt Makes College a Risky Investment

Our findings, especially those that examine household decision-making, emphasize that while the return to higher education is high, it is not a safe investment for many households. The deterrent effect of risk survives the ability of agents to feasibly debt finance college with student loans. The main force here is that debt makes higher education riskier for student borrowers, suggesting that alternatives that are mindful of risk may be more effective. In turn, the focus of the policy experi...
