Dr. Yip Swee Chooi on Memorizing a 1774-page Chinese-English Dictionary

The video about Dr. Yip Swee Chooi’s memorizing a 1774 page dictionary keeps coming up in discussions about memory, so I decided to make a blog post that I can link to to reference the video (easier to find than the YouTube video).

Here is the video:

Thanks for posting this! I used a similar technique to memorize the Gospel of Mark, but that only has 678 loci slots, not 57,000. :) I'm relieved he didn't memorize the prose definitions verbatim ... that would seriously mess with my head. Although Foer mentions those "Shass Pollak," who seem to have memorized the exact layout of 5000+ pages of Talmud...I wonder if those texts had any rhythm or rhyme.

How could he learn how to spell all those words?

I'm not sure how he did it, but maybe look into some of the techniques used for school spelling bees (prefixes, suffixes, etymologies). Some of those kids take it really seriously. :)
