The Memory Masters
Vaystrem writes "Wired's Article 'The Masters of Memory' details the outcome of the recent U.S. Memory Championship ,where 'three dozen people who had, in just five minutes, memorized the positions of 52 cards in a shuffled deck and were now happily organizing cards in a new deck into the same order as the pack they had memorized.'" The article includes details of "the mind numbing upcoming world championship. Could you in a half hour 'memorize a random string of thousands of 1s and 0s'?" I'm still working on the mnemonic alphabet.

... It really does seem to go something like 1,2,3,4,5,6,7,lots. We seem to have a distinction of the innate "three-ness" of a scene, for example, and don't need to count to know that the quantity of X is three.
:-) The thing is that we can do it recursively, with a bit of effort, so you remember group A is (21,63,37,78,39) and group B is (25,544,62,150,311). It's easier to recall both sets if you first subdivide into the largest quantum you can most-easily recall, and remember the sets individually. Normally you can do this for the number of sets in your personal quantum, so if you can easily remember 5 numbers in a set, this helps you remember 25. It's not "free" of effort, but it's a lot easier than remembering 25 numbers straight off..
The brain seems to actually have the sort of grasp of numbers that we sometimes ascribe to "Neanderthals"
Different people vary with the maximum innate value they just grok, with most people coming in about 5 or 6, rarely do you get 7, and vanishingly rarely do you get 8.
What has this to do with memory, you cry! Well, in the same fashion, we can innately recall small numbers of things, without doing an exhaustive search. This is useful for PIN numbers

If technology advanced enough that you could download memories from the brain of someone with extremely good memory, would the brain be an illegal recording device? I read once that your brain can recall almost everything. Some of the material merely needs coaxing out (like with hypnosis). Hmmm....

When they're not in competition they're memorizing 1's and 0's for me. I keep them in my basement as a backup in case my harddrives crash.

I guess the thinking is, "well they do very well on tests". Sure, that's because they memorized everything. But do they Understand? There's a difference between knowing something, and really understanding what it means. I really think schools should focus more in testing how well a student really understands a subject, perhaps demonstrate the ability to teach it to someone else.
In Schacter's memory book, an anecdote is presented about the 1999 National Memory Champion. She commented that she relied on post-its to get through the day.
It's not really ironic because memory competitions test how transient your memory focus is. Post-Its help those with attentional problems of memory.
In other words, these memory champions don't have all-around good memory skills.

PIN codes, phone numbers, ID numbers, passwords, registration numbers.
They are hardly ever as long as 150 digits but they are EXTREMELY common.
> Instead, our brains are much better suited to recognizing patterns
RTFA, that's what the whole concept is based on. Just associate symbols with patterns/images and then create a story/image based on the set created.

Does anyone remember that Happy Days where the Fonz helps Richie and Potsie study for a Biology test by turning it into a rock song that they play in class? Was that just a weird dream I had? I swear it actually happenned. Well, ever since then I turn things into songs in my head to remember them -- and it works really well. I mean, I added a tune to the Constitution and remembered the entire first two articles. It's kinda scary.
The human brain has a limited space for memory, so if you try to remeber too much you will end up forgetting other important stuff. That guy that memorized the 3000 long binary number probably can't remember his mother maiden's name now, or where he parked his car.
Remembering a sequence of 52 cards is actually not that hard. Well, okay, it's hard, but it's doable. I used to be able to do it with relative success, but I haven't practised in over 3 years.
:)
There are several techniques, and most of them use grouping and storylining. For example, this is the one I used:
Every card gets three possible meanings -- a subject, an object, and an action. Then you draw the cards in threes and make up a story on the spot. E.g. say you drew a two-hearts, jack-spades, and six-diamonds. In your designation chart, these cards have the following meanings:
two-hearts: subject: Madonna; action: seduce; object: boobies
jack-spades: subject: drug dealer; action: wave above one's head menacingly; object: bling-bling
six-diamonds: subject: bank attendant; action: pay; object: a wrapped packet of dollars.
So your combination becomes: Madonna menacingly waving a wad of dollars above her head. The key here is to visualize these things and make up a continuous story, as if describing what happened to you on the way to work. (Out of the door, I saw Madonna waving menacingly a wad of dollars above her head. I came to talk to her, and apparently she was angry because a drug dealer shot her car (jack-spades/three-spades/four-diamonds). I offered her a ride, and on the way to her house we saw from the windows of our car Saddam Hussein trying to hump a church building (king-spades/four-hearts/ten-crosses).). It's important to tie the previous action to the next (saw through the windows of our car), so you don't lose the sequence of events.
The cards are grouped by subjects -- all hearts have to do with sex, all diamonds have to do with money, all spades have to do with criminal element, and all crosses have to do with cults and religion. Usually just three possible meanings per card is not enough, because it can always be that you just CAN'T make something meaningful out of a combination ("Bank teller seducing an electric chair" takes... a lot of imagination to visualise, though if you manage, you'll never forget a six-diamonds/two-hearts/five-spades. Ever).
Sometimes you sure make up very amusing combinations. E.g. among the ones I recall is Saddam Hussein licking a cash register (king-spades/ace-hearts/ten-diamonds), Marylin Monroe wearing a punctured car tire on her neck (queen-hearts/queen-diamonds/three-spades), and Bill Gates seducing a bill fold (king-diamonds/two-hearts/two-diamonds), though this one could have actually happened for all I know.
The weirder you make your combination, and the more vividly it stands out in your imagination, the higher is the chance that you will remember it.

You can use it for any serialization of numbers, and cards are very simple. You can also do this with binary (but be good at converting two digit decimal to binary and back).
Develop a set of references for most two digit numbers that have meaning to you.
Some I use for example are: 07 - think of James Bond, 22 think of 22 caliber pistol, 13 think of unlucky. It also helps to have a set for single digits, 7 think of lucky for example.
Then when you look at a series of numbers, all you do is make a story to fit the numbers together.
For example:
1307877299220713442
The story I would make up to remember this:
Unluckily, James Bond found a RX7 to get away back when I was born. During the getaway, agent 99 shot a 22 pistol at Bond but she was unlucky, and got shot with a 44 magnum twice.
(The story is often shorter in your head, but I wanted to make it readable for you guys)
In essence instead of remember numbers, you are remembering the plot to a story.
Without looking above here is the number set: 1307877299220713442
13 - Unlucky
07 - Bond
87 - Year of RX7 I had a long time ago
72 - Year I was born
99 - Agent 99 (from Get Smart)
22 - 22 pistol
07 - Bond again
13 - Unlucky
44 - 44 Magnum
2 - Twice
If you get your associations down for the number pairs you can create little stories and easily remember 100 digit or more sequences of numbers.
For card tricks, just add color to the story, I use blue and green to denote the difference between hearts and clubs, or sometimes will mix in the heart or spade or club reference into the story (i.e. the Queen took her Spade, etc)
Most people are impressed if you can just remember the number sequence of a deck of cards and not even bother with the suit, so if the extra colors for the suits throw you, just do the number order of the cards.
Start with a deck of cards, and I will guarantee you in a few hours or day, you can easily do this.
Just make up the story as you look through the deck, the faster you know your associations for a story, the faster you can remember the cards. You should be able to remember an entire deck by literally flipping through them as fast as you can read them.
Happy memorizing...
But... that IS what they do!
They encode the data into easily rememberable kind they don't compress it, but rather expand - creating stories, images, pictures, sentences, through the "mnemotechnic memory" technique. Then they decode it just the same way.
Say, you have a memory medium that can remember arbitrary values from 0 to 256, it has a plenty of room, but it tends to float lightly, i.e. 128 may become 120 or 140 or 100, but not 20 or 210. So for your purpose instead recording byte values, you recode them to binary and record every "1" as two 255's and every "0" as two 0's, then record them. You need 16 bytes of your diskspace to store 1 byte, but it will NOT get lost - only really strong corruption could change the results...

Perhaps the most famous, certainly one of the most cited, papers in cognitive psychology is George Miller's 1956 paper "The magic number seven plus or minus two: some limits on our capacity for processing information." The 7+/-2 rule is one of the few, true "laws" in psychology. It describes the number of items that can be held online in working memory by the average individual. I won't even begin to touch here the myriad theories that proposes mechanisms for this limited capacity.
The technique you talk about regarding the grouping of multiple memoranda into a single unit is called "chunking" and was studied by another great in psychology, the late Herb Simon of CMU. He and Bill Chase found that chunking was basically what set chess masters apart from novices. They saw entire board configurations at once, rather than the relation of individual pieces.
The ability to appreciate the numerosity of multiple items without counting is called subitizing. I know less about this, but the average person can subitize up to about five items.
Anway, just wanted to give credit where it's due for what has become pop psychology fodder.
This is a typical anonymous slashdot troll. The poster is trying to put down someone else's post where that person discovers that his abilities are not unique, as he'd long suspected, but rather are a deep and complex portion of the human experience. I know that the AC was expecting some kind of epiphany to result from this, but basically, he's just putting someone else down because he had no intelligent comment whatsoever to make and nothing to add to the discussion.
