A good example is remembering names: when one’s name is “John Baker”, it is so much easier to remember by silently adding “the” in front of it.

We’re also very good at remembering salacious stuff. I tried constructing my own memory palace for a grocery shopping list that included cream cheese. If you mentally make Claudia Schiffer take a bath in cream cheese, you’ll never forget that. (I read the book at least 10 years ago and still haven’t…)

0: 's'

1: 't'

2: 'n'

3: 'm'

4: 'r'

5: 'l'

6: 'sh'

7: 'k'

8: 'v'

9: 'p/b'

To use it, just make images/stories that correspond to the digits you need to remember.

The more absurd the story, the less likely you'll forget.

E.g. pi (3.14159265359 ) could be the images of these objects: mit, rat, lab, Noah, shell, mail, bee. Then just sew them together in a story e.g. someone drops a mit, it lands on a rat, the rat runs up to someone in a lab, it's Noah, he throws a shell, it knocks over some mail which lands on a bee.

I don't use it often, but I like to memorise any 8+ digit door code when checking into a serviced apartment or airbnb, in case I forget my phone and would otherwise be without the code.

I can teach you right now, the first 50 digits of Pi, after the 3 and the comma. And with almost zero effort. Just memorize the text below...

Congrats you little, little genius.

"A poem I write carefully to encode every new digit silently, reminding curious beginners how we can decipher each number in hidden text you see.

Whenever you go through beautiful green wilderness at midnight, remember when I carefully recited a simple paragraph and practiced repeating the numbers again; I remembered."

[1] i memorized 3,141 digits of pi to prove a point (https://www.youtube.com/watch?v=KAjkicwrD4I)

Edit: I had only skimmed through the OP when I posted this comment, turns out both the video and this article talk about the memory palace method! They diverge in the way it's applied though, with the AiP video associating digits with real life locations

Funny thing is that another kid memorized pi to over 500 digits just from pure memorization.

I don't find the memory palace tricks helpful at all though. I think that is a consequence of my Aphantasia and something I only realised recently. I can't visualise a memory palace so placing things in it is impossible!
