“The Memory Palace is one of the most powerful memory techniques I know. It’s not only effective, but also fun to use – and not hard to learn at all.
The Memory Palace has been used since ancient Rome, and is responsible for some quite incredible memory feats. Eight-time world memory champion Dominic O’Brien, for instance, was able to memorize 54 decks of cards in sequence (that’s 2808 cards), viewing each card only once. And there are countless other similar achievements attributed to people using the Memory Palace technique or variations of it. Even in fiction, there are several references to the technique. In Thomas Harris’ novel Hannibal, for example, serial killer Hannibal Lecter uses Memory Palaces to store amazingly vivid memories of years of intricate patient records (sadly, it was left off the movie).
Of course, most of us are not in Dominic’s memory championship line of business (or in Hannibal’s line of business for that matter). But still, the Memory Palace technique is amazingly effective in all kinds of endeavors, such as learning a foreign language, memorizing a presentation you’re about to deliver, preparing for exams and many others – even if all you want is to jog your memory.”
