What is it with index cards ? .t3_17ck5la._2FCtqQzlfuNSwVMUZMM3 { postTitleVisitedLinkColor: #9b9b9b; postTitleLinkVisitedLinkColor: #9b9b9b; postBodyLinkVisitedLinkColor: #989898; } So I posted a while ago about my journey into the zettlekasten and I have to admit I still enjoy using this system for notes.I must say, I am an avid note taker for a long time. I write ideas, notes from books, novels, poems and so much more. I mainly used to use notebooks, struggle a while with note taking apps and now I mainly use two kind of things : index cards (A6) and an eink tablet (the supernote) for different purpose of course, the index cards for the zettelkasten and the eink tablet for organization and my work. To be honest I used to consider myself more a notebooks kind of person than an index cards one (and I am from France we don't use index cards but "fiche bristol" which are bigger than A6 notecards, closer to an A5 format)Still, there is something about index cards, I cannot tell what it is, but it feels something else to write on this, like my mind is at ease and I could write about ideas, life and so many stuff covering dozens of cards. I realize that after not touching my zettelkasten for a few week (lack of time) and coming back to it. It feels so much easier to write on notecards than on notebooks (or any other place) and I can't explain it.Anyone feeling the same thing ?

Some of it may involve the difference in available space versus other forms of writing on larger pages of paper. Similarly, many find that there is less pressure to write something short on Twitter or similar social media platforms because there is less space in the user interface that your mind feels the need to fill up. One can become paralyzed by looking at the larger open space on a platform like WordPress with the need to feel like they should write more.
With index cards you fill one up easily enough, and if there's more, you just grab another card and repeat.
cross reference with Fermat's Last Theorem being easier to suggest in a margin than actually writing it out in full.

it became clear that Fermat's Last Theorem could be proven as a corollary of a limited form of the modularity theorem (unproven at the time and then known as the "Taniyama–Shimura–Weil conjecture"). The modularity theorem involved elliptic curves, which was also Wiles's own specialist area.[15][16]
Elliptical curves are also use in Ed25519 which are purportedly more robust to side channel attacks. Could there been some useful insight from Wiles and the modularity theorem?

Or do you recall jotting down formulae for molecules and compounds in the margins of your chemistry textbook?
I can't help but think of one of the biggest and longest standing puzzles in mathematics in Fermat's Last Theorem. He famously wrote in the margin of a book that he had a proof. but that it was too large to fit in the margin.
