1. Are there symbols for 'supported by' or 'contradicted by' etc. to show not quite formal logical relations in a short hand?

In addition to the other excellent suggestions, I don't think you'll find anything specific that that was used historically for these, but there are certainly lots of old annotation symbols you might be able to co-opt for your personal use.

Evina Steinova has a great free cheat sheet list of annotation symbols: The Most Common Annotation Symbols in Early Medieval Western Manuscripts (a cheat sheet).

More of this rabbit hole:

(Nota bene: most of my brief research here only extends to Western traditions, primarily in Latin and Greek. Obviously other languages and eras will have potential ideas as well.)

Tironian shorthand may have something you could repurpose as well: https://en.wikipedia.org/wiki/Tironian_notes

Some may find the auxiliary signs of the Universal Decimal Classification useful for some of these sorts of notations for conjoining ideas.

Given the past history of these sorts of symbols and their uses, perhaps it might be useful for us all to aggregate a list of common ones we all use as a means of re-standardizing some of them in modern contexts? Which ones does everyone use?

Here are some I commonly use:

Often for quotations, citations, and provenance of ideas, I'll use Maria Popova and Tina Roth Eisenberg's Curator's Code:

• ᔥ for "via" to denote a direct quotation/source— something found elsewhere and written with little or no modification or elaboration (reformulation notes)
• ↬ for "hat tip" to stand for indirect discovery — something for which you got the idea at a source, but modified or elaborated on significantly (inspiration by a source, but which needn't be cited)

Occasionally I'll use a few nanoformats, from the microblogging space, particularly

• L: to indicate location

For mathematical proofs, in addition to their usual meanings, I'll use two symbols to separate biconditionals (necessary/sufficient conditions)

• (⇒) as a heading for the "if" portion of the proof
• (⇐) for the "only if" portion

Some historians may write 19c to indicate 19th Century, often I'll abbreviate using Roman numerals instead, so "XIX".

Occasionally, I'll also throw drolleries or other symbols into my margins to indicate idiosyncratic things that may only mean something specifically to me. This follows in the medieval traditions of the ars memoria, some of which are suggested in Cornwell, Hilarie, and James Cornwell. Saints, Signs, and Symbols: The Symbolic Language of Christian Art 3rd Edition. Church Publishing, Inc., 2009. The modern day equivalent of this might be the use of emoji with slang meanings or 1337 (leet) speak.

1. If you have experienced trouble in rememberingdates try the following system which has proved beneficial to at least onestudent.

Maxfield suggest drawing out a timeline as a possible visual cue for helping to remember dates. He seemingly misses any mention of ars memoria techniques here.

1. My composition is greatly aided both 20 years' worth of mnemonic slurry of semi-remembered posts and the ability to search memex.craphound.com (the site where I've mirrored all my Boing Boing posts) easily. A huge, searchable database of decades of thoughts really simplifies the process of synthesis.

Cory Doctorow's commonplace makes it easier to search, quote, and reuse in his process of synthesis.

1. Excerpting requires effort and thus combats natural laziness; inhis regimen there is no reading without taking notes, which would be idleand vain, and no time wasted because every free moment can be put to usereading over one’s notes (seeA,p. 84).

Even early in the history of note taking treatises Jeremias Drexel acknowledges the idea that good note taking, and particularly excerpting, takes work.

Modern students seem to have now lost both the ars memoria as well as the note taking arts which helped supplant it. We really need to be able to regain both of these traditions, but it will obviously take commitment to do the work.

2. Drexel emphasizesthe difficulty of image-based arts of memory and how short-lived are theirresults: “Great labor places so many images of things in this treasury ofmemory; but no amount of labor has managed to preserve them there forlong without excerpts” (A, p. 3). Instead, for Drexel excerpting is the onlysure way to retain material for the long term. Drexel insists too that, farfrom detracting from memory, note taking is the best aid to memory.

Jeremias Drexel is certainly a writer who complains about the work of the ars memoria, particularly for long term memory and supplants it with writing/note taking.
