In physics, fields describe the distribution of forces in space. Their description thus requires the knowledge of magnitude and direction. Both are expressed through field contours; field forces act in the direction of the contours, and the distance between the contours indicates their magnitude. (The closer the contours are together, the larger the force.) In an electric field the direction of the field is given by the electric charge of the charged sources. If the charge is negative, the field is directed toward the charge. All electric fields begin on a positive charge and end on a negative charge. If two positive charges interact, their forces are directed against each other. This creates a repellent force as shown in the illustration. (The same occurs with two negative charges, because their respective forces also act in opposite directions.)

One of Murray’s most helpful advisers on American words was aGerman living in Boston, Carl Wilhelm Ernst. Ernst was a journalist, theeditor of the Beacon newspaper, and a former Lutheran minister who hadmoved to America when he was eighteen years old. Murray wrote to thejournalist in a panic when completing the entry for public school. ‘In workingat this, I overlooked the fact that we had nothing for the US use, and findmyself now almost stranded, and unable to complete the article.’ He wrote toErnst asking for illustrative quotations and for clarification on the Americansense of the word: ‘It is said to be synonymous with Common School. I donot know which of these is the official appellation, and which the popular, orwhether they are both so used. We should like to know this. The designationin England has a long and rather complicated history coming down from theL. publican schola, which is already used by Jerome of Quintilian.’Murray started the entry by defining the use of public school in Englandas ‘originally a grammar-school founded or endowed for the use or benefit ofthe public’ but more recently, in the nineteenth century, as ‘the old endowedgrammar-schools as have developed into large boarding-schools, drawingfrom the well-to-do classes of all parts of the country or of the empire’. Henoted that ‘the ancient endowed grammar-schools or colleges of Eton,Winchester, Westminster, Harrow, Rugby, Charterhouse, Shrewsbury’ aresometimes referred to as ‘the Seven Public Schools’. He contrasted this senseof public school with that in Scotland, the British colonies and the UnitedStates of America, as a school provided at the public expense, usually free.Above six American quotations spanning from 1644 to 1903, Murray added alengthy note, thanks to Ernst’s advice, ‘The term has been used in NewEngland and Pennsylvania from the 17th c., and has been adopted in all Statesof the American Union. An early synonym was “free school”, and a later onein some States, “common school” which is now however generally confined toa school of the lowest grade or “public elementary school”.’
I recently heard someone talking about the differences in public vs. private schools in Britain and America as having opposite definitions.

This search for order pushes one to seek out under-lying patterns and trends, to find relations that may betypical and causal.
Finding order and relations (and their particular types), is a form of linking ideas found in some of the more complex zettelkasten and knowledge management spaces. It's not as explicit here and he doesn't seem to be focusing on stating or writing explicit links within his notes. He does, however, place some focus on the quality and types of links he's making (or at least thinking about), something which isn't frequently seen in the current PKM space. For example, no one is creating user interfaces that show links between ideas which are opposite (or in opposition or antonym relation) to each other.
here are several ways I havefound useful to invite the sociological imagination:
C. Wright Mills delineates a rough definition of "sociological imagination" which could be thought of as a framework within tools for thought: 1. Combinatorial creativity<br /> 2. Diffuse thinking, flâneur<br /> 3. Changing perspective (how would x see this?) Writing dialogues is a useful method to accomplish this. (He doesn't state it, but acting as a devil's advocate is a useful technique here as well.)<br /> 4. Collecting and lay out all the multiple viewpoints and arguments on a topic. (This might presume the method of devil's advocate I mentioned above 😀)<br /> 5. Play and exploration with words and terms<br /> 6. Watching levels of generality and breaking things down into smaller constituent parts or building blocks. (This also might benefit of abstracting ideas from one space to another.)<br /> 7. Categorization or casting ideas into types 8. Cross-tabulating and creation of charts, tables, and diagrams or other visualizations 9. Comparative cases and examples - finding examples of an idea in other contexts and time settings for comparison and contrast 10. Extreme types and opposites (or polar types) - coming up with the most extreme examples of comparative cases or opposites of one's idea. (cross reference: Compass Points https://hypothes.is/a/Di4hzvftEeyY9EOsxaOg7w and thinking routines). This includes creating dimensions of study on an object - what axes define it? What indices can one find data or statistics on? 11. Create historical depth - examples may be limited in number, so what might exist in the historical record to provide depth.

Video about the Double-Bubble Map: https://youtu.be/Hm4En13TDjs
The double-bubble map is a tool for thought for comparing and contrasting ideas. Albert Rosenberg indicates that construction of opposites is one of the most reliable ways for generating ideas. (35:50)
Bluma Zeigarnik - open tasks tend to occupy short-term memory.
I love his compounding interest graphic with the steps moving up to the right with the quote: "Even groundbreaking paradigm shifts are most often the consequence of many small moves in the right direction instead of one big idea." This could be an awesome t-shirt or motivational poster.

And dry grass singing
Dry grass to me seems so lifeless, basically dead. But as the stanza before, this is like pairing opposites. If dry grass does sing, I imagine it's a sad song.

They took the air and they swarmed as one
The end of this first song on Spoils recalls the end of the first song on the Farewell Sorrow album, particularly the lines:
Life is but Death's own right-hand man<br> In every piece of his own left-hand business.<br> So arm in arm, we'll run toward that pair<br> And we as they, joined and double-threaded
Similarly Grief and Joy are "as one", and the parallel with Life and Death brings us full circle to the tacit allusion in this song's title to Hamish Henderson's Flyting o' Life and Daith.

we must be able to employ persuasion, just as strict reasoning can be employed, on opposite sides of a question, not in order that we may in practice employ it in both ways (for we must not make people believe what is wrong), but in order that we may see clearly what the facts are, and that, if another man argues unfairly, we on our part may be able to confute him. No other of the arts draws opposite conclusions: dialectic and rhetoric alone do this.
In order to persuade one must address and understand all facts in a situation. Art of opposites.
