More From Tammet

The mathematical capabilities of autistic savants are often among of the most difficult parts of their repertoire to understand or explain. These may include lightening-fast calculation or other feats of computation. And oftentimes, as in Daniel Tammet's case, their description of numbers as having color and texture or shape is likewise difficult to conceive. Tammet is famous for reciting pi accurately to 22,000 digits, a virtually inconceivable accomplishment, but aided by his of pi as not just a number, but a landscape so-to-speak.
Interestingly in his new book Tammet hypothesizes that his math prowess stems from "abnormal cross-communication" between areas of the brain that govern math skill and those that govern language, and specifically syntactic rules, which normally are separate. He points out that the two areas (left parietal lobe and and left frontal lobe) lay physically next to each other in the brain, and that his "numerical abilities are rapid, intuitive, and largely unconscious" very much like the way most people speak and process language. Also, he notes that along with his mathematical talents he has already learned a dozen languages, and very easily picks up new languages to a conversational level. His explanation is purely intuitive and speculative (so far as I know), but seems to make as much sense as anything else offered by others.

In a totally different section of the book (on logical thinking) Tammet throws out this simple, yet interesting old puzzle-example of Lewis Carroll's:

a) My saucepans are the only things I have that are made of tin.
b) I find all your presents very useful.
c) None of my saucepans are of the slightest use.

...and then asks, what is the 'ultimate' logical implication arising from these statements? (answer below)
answer: your presents are not made of tin

Sleep and Learning

A lot of research, as well as longstanding folk wisdom, contends that the number of hours of sleep one gets is very important for the well-being of an organism, specifically humans. This study on memory/learning further argues that it is not just the length of sleep, but 'quality' of sleep which is a major factor.

"Embracing The Wide Sky"

WOW!! I snapped up autistic savant Daniel Tammet's latest book hot off the bookstore shelves the other day ("Embracing The Wide Sky" here and here), and am about 2/3 of the way through it, but can say I LUV it! Hits on a wide range of cognitive issues. And Tammet's perspective is of course utterly unique, as an articulate, thoughtful savant who can introspectively analyze how his own mind works. The book actually includes a lot of references to more standard journal literature as well, but Tammet never blindingly accepts the conclusions of academic researchers when his own intuitive understanding of how the brain works runs counter to the party line of academics. Plenty of outside-the-box thinking here on subjects where outside-the-box thinking is much needed, and sometimes difficult to come by.

Although he doesn't go into great depth in any given area, Tammet touches upon a shmorgasbord of cognitive subjects including brain plasticity and re-wiring, intelligence testing, memory, language acquisition and processing, number instinct, perception, and creativity. And interestingly, he believes many of the talents of savants are not as special as they appear, and in some cases are even accessible by non-savants.
A very interesting read for anyone interested in the workings of the brain.

Monty Hall Redux

The "Monty Hall problem" (here and here) is one of the most widely-discussed and popularized math problems of all times, and it just keeps going and going. There will soon (well, June) be an entire book out devoted to it from Jason Rosenhouse: "The Monty Hall Problem: The Remarkable Story of Math's Most Contentious Brain Teaser." Should be a good read for mathematicians and lay folks alike.

Pinker On Personal Genomes and Behavioral Genetics

Nice NY Times article by the always eloquent Steven Pinker on the pertinence of personal genomics (he has had his own genome sequenced and released, and here he tries to analyze what it all means as we approach a time when everyone will have routine access to their personal genomes).

Riemann Hypothesis Prediction

John Brockman's "Edge" group was asked, as their yearly question this year, what scientific development do they expect to see "change everything" within their lifetime. Clifford Pickover's answer here, is that the Riemann Hypothesis, one of math's most enduring unsolved problems, will be proven.

(Worth reading many of the other Edge respondents as well...)

More Ambiguous Ambiguity

Ambiguous headlines straight off the press: here.

(How we quickly and successfully disambiguate meanings in a rapid stream of speech, or even text, is one of the most perplexing questions in linguistics.)

In the next sentence, the number of occurrences of 0 is 1,
of 1 is 7, of 2 is 4, of 3 is 1, of 4 is 1, of 5 is 1,of 6 is 1, of
7 is 1, of 8 is 2, and of 9 is 1.

Brain Games

"Cognitive Daily" ran a post on "brain games" Xmas Eve and also asked for further suggestions from readers. If you like number, word, or other mental puzzles it may be worth checking out for some online possibilities you weren't aware of. And of course many more links are possible.
(The actual focus of the post was on the notion that such mental exercise can help maintain sharper cognitive function as we age.

Everything Is Relative....

A snail is mugged by two turtles. When the police asked him what happened, he said, "I don't know. It all happened so fast."

Pat: Mike, I'm calling you from the freeway on my new cell phone.
Mike: Be careful Pat. They just said on the radio that there is a nut driving the wrong way on the freeway.
Pat: One nut? Hell, there are hundreds of them!

"Zaphod Beeblebrox's Brain and the Fifty-ninth Row of Pascal's Triangle"

According to Clifford Pickover the above is the "all-time strangest title" for a published serious paper in mathematics.
And for the non-math-phobes out there here is that paper.
