Announcing an experimental new tool for thought
@michael_nielsen and I have been wondering: what happens if we take powerful ideas from cognitive science and deeply integrate them into explanations? Our first experiment in a new "mnemonic" medium:https://quantum.country/qcvc

One reason books are hard is: readers run all the feedback loops. "Did I really get that? Should I flip back?" This demands attention to both the content and also the meta. We interleave prose and lightweight spaced repetition to take some of that work off the reader's plate.pic.twitter.com/vy7ewONxYh

Imagine you’ve just finished a tough section. We say: catch your breath; let’s take stock. We quickly flick through what we learned. Got it all? Great, we’ll review again later, when you've probably forgotten. Something slipped your mind? OK: we’ll review that bit sooner.

Something felt totally mysterious? You just learned that you left the stove on before you left the driveway. It doesn’t feel so onerous to read a section again on the spot. It would feel much more tiresome to realize that a few days later… so you might not reread the section.

One reader said: "There was a section where I tanked them all. I thought: wow, I clearly didn’t get whatever I was supposed to get. […] So then I went back and asked ‘why am I not retaining this?’ I’ve never had that with a textbook before: usually the problems are at the end."

That's the retrospective effect. The *prospective* effect is a feeling of safety. Once you’ve read a few sections, now you read each new passage knowing that you’ll have this quick check at the end. It's a save point every few minutes. You're not going to miss anything.

Then, the next day, you'll get your invitation to your first review session. A few minutes of study, repeated over about 20 sessions over the next year, and you'll remember everything forever. It feels like cheating. One reader: "The bang for the buck is extraordinary."pic.twitter.com/j2JbYkcmM1

Lots more to share: how the mechanics affect the prose and vice-versa; how we designed the interactions to be super light-weight; the impact of self-assessment on the design; conveying exponential progress; exploring new media via serious—not toy—content; etc. Stay tuned!

I recall
@kmett talks about spaced repetition in one of his talks. It must work for him - he is probably the best live coder I’ve ever seen. -
Watch Ulf Norell some time and I’ll come off as an amateur. :)

Re-read a passage after 5 mins 1 hour 1 day 1 week 1 month That should do it.
