    1. Recent reviews on DFT may be found in Jones and Gunnarsson (1989) and Dreizler andGross (1990)

      This is before the PAW method came along (Blochl '94), so probably nothing method-specific.

    1. In contrast, activities of invention almost always progress towards the creation of new or better things but not necessarily through refi nement. Normally we invent by combining a set of things we already understand how to create into larger, more complex, or more capable things that did not previously exist.

      The purpose of HCI as invention:

      • "understanding can sometimes decrease" due to complexity of making things

      • "things are more capable"

    2. Activities of discovery can have a variety of aims, including generating rich, empirically based descriptions, and creating new theoretical understandings

      The purpose of HCI as discovery:

      •"form framing truths"

      • elaborate to "progress toward improved understandings"

      • refined to "explain more phenomena or to be more predictive"

      • "developing and testing competing ideas"

    3. Another way of understanding technical HCI research is by contrasting it with other types of technical work that is not research. For our purposes, research can be seen as having the creation of reusable knowledge at its core. More specifi cally technical HCI research emphasizes knowledge about how to create something (invention) but also knowledge that might be reused to assist in the creation of a whole class of similar things or even multiple types of different things.

      HCI research definition. Contrast this with the previous development-based definition.

    4. In an interdisciplinary setting such as HCI, we often shift between disciplines that have stable and functional but potentially con-tradictory world views. In doing so, we are confronted with the need to select and use (or at least appreciate, understand, and evaluate) a wide range of methods and with them a wide range of expectations and values.

      The interdiscipliinary nature of HCI provides an impetus to consider non-STEM perspectives but can also reveal frictions between approaches, practices, values, and goals.

    5. Technical HCI focuses on the technology and improvement aspects of this task—it seeks to use technology to solve human problems and improve the world. To accom-plish this, the fundamental activity of technical HCI is one of invention —we seek to use technology to expand what can be done or to fi nd how best to do things that can already be done.

    1. How strange! She looked up at the pale sky, and all she thought was, “Yes, it was the most successful party.”

      There is no denying that Laura thinks a party with the dead is not a successful party. So I supposed that it is a verbal irony. There are also many ironies in The Moonstone. How can we track the irony through a computational method? I think this example of irony gives me an inspiration. There are some passive words which indicate the meaning that is ostensibly expressed in this paragraph, but "the most successful" are positive words. The strong contrast can be a typical symbol for the computer to recognize irony.

    1. Do you have questions about how best to moderate your online community? CivilServant, software created at the MIT Center for Civic Media, helps online communities do your own A/B tests of moderation practices.

      This is an interesting SaaS system for exploring how to create good moderation systems.

    1. I always found it incredible. He would start with some problem, and fill up pages with calculations. And at the end of it, he would actually get the right answer! But he usually wasn’t satisfied with that. Once he’d gotten the answer, he’d go back and try to figure out why it was obvious. And often he’d come up with one of those classic Feynman straightforward-sounding explanations. And he’d never tell people about all the calculations behind it. Sometimes it was kind of a game for him: having people be flabbergasted by his seemingly instant physical intuition, not knowing that really it was based on some long, hard calculation he’d done.

      Straightforward intuition isn't just intuition.

    1. It reminds me of the New Math of the 1960s, which fashioned mathematics in a dramatically more abstract, more analytic way than before. And if Johnny Can’t Add with the new math, maybe Jenny Won’t Code with an overly abstract presentation of computing. Papert points us in the opposite direction

      It’s a source of power to do something and figure things out, in a dance between the computer and our thoughts. The inversion, starting with computing as a formal thing to understand and then come to the application later, takes away its power.

    2. One striking comment follows a couple of pages later, where the phrase “computer-aided instruction” evokes in Papert the unappealing idea that “the computer is being used to program the child” — his vision, of course, is that the child must program the computer.
    3. In 1980, Seymour Papert published the book “Mindstorms: Children, Computers, and Powerful Ideas” [2]. Papert was co-director, under Marvin Minsky, of the MIT Artificial Intelligence Laboratory from 1967 to 1981. Previously, he had worked with Jean Piaget in Geneva. Piaget was a developmental psychologist best known for pioneering the learning theory known as constructivism: simply put, that learners construct new knowledge (in their minds) from the interaction of their experiences with previous knowledge. Papert, in turn, developed the theory of constructionism, adding the notion that learning is enhanced when the learner is engaged in “constructing a meaningful product.”
