Gifts of knowledge to humanity There are many commonalities we can admire in these endeavors: the dazzling leap of imagination, the broad scope of applicability, the founding of a new paradigm. But let’s focus here on their form of distribution. These are all things that are taught. To “use” them means to learn them, understand them, internalize them, perform them with one’s own hands. They are free to any open mind. In Hamming’s world, great achievements are gifts of knowledge to humanity. Bret Victor, The Art of Doing Science and Engineering: Learning to Learn knowledge
Hamming-greatness Hamming-greatness is tied, inseparably, with the conception of science and engineering as public service. This school of thought is not extinct today, but it is rare, and doing such work is not impossible, but fights a nearly overwhelming current.

Up and Down the Ladder of Abstraction An Essay by Bret Victor worrydream.com The most powerful way to gain insight into a system is by moving between levels of abstraction. Many designers do this instinctively. But it's easy to get stuck on the ground, experiencing concrete systems with no higher-level view. It's also easy to get stuck in the clouds, working entirely with abstract equations or aggregate statistics. This interactive essay presents the ladder of abstraction, a technique for thinking explicitly about these levels, so a designer can move among them consciously and confidently.

What is unspoken Ethnographic studies are distinct from ethological research in other species because we can speak with our subjects and ask them questions. This has tremendous value, but much of what humans do is not spoken, and we also observe, count, and measure. researchux
Research questions From my records, research questions emerged that I never expected when I was making them. notetakingquestions
Quantitative data collection Quantitative data collection involves systematic and repetitive observations on the same set of variables.
Anthropological rapport Accurately capturing how people spend their time is contingent not only on systematic data collection, but also on participants moving in a relaxed and normal manner through their daily activities. Just as primatologists habituate their subjects to their presence, anthropologists first must develop rapport and trust with the communities in which they live. ux
Scan samples, focal follows Scan samples and focal follows are two commonly used behavioral observation methods. During a scan sample, randomly selected individuals are located at specified time intervals, usually every ten to fifteen minutes, and the observer instantaneously records what the participant is doing. Focal follows complement scan samples by documenting the continuous sequence of an individual's activities. During a focal follow, each subject is observed over a period of several hours with each change in activity recorded with a start and stop time.
Multitasking In most traditional societies children help care for their younger siblings. However, it is often the case that a child minding his younger sibling does so out of the corner of his eye while playing with other children. Is this play or child care?
A nested classificatory hierarchy I organized behavioral codes to contain several levels of information. As in this example, if a child is outside playing with friends while minding her two-year-old sister, the activity was coded as 675: the 600 signifies noneconomic activity, the 70 that it is playing, and the 5 that it is playing while in charge of a child. All activities were coded in this way. A nested classificatory hierarchy preserves both detail for future research and flexibility to lump or disaggregate activities for analyses. This method of nesting information carries over into many kinds of coding and classificatory schemes. research
A child's question Because they live so successfully in their world, we expect our subjects to readily explain the strategies that underlie the behaviors we observe. This can be trying, because from their point of view we are asking the obvious, a child’s question.
