Mental Calculation And Memory Champions [Rudiger Gamm]

[Havaldur]

Could anyone recommend material or techniques that are an aid in the
ability of mental calculation of large numbers and memorizing large
amounts of data with various memory systems. I bought several books,
and read about parts of each -- I plan to just read the rest of them
to get a grasp of the various concepts, implement them, and modify to
fit a particular memory problem I face.

Apparently, he spent time learning he memorized tables of functions,
exponential functions, logarithmic functions, multiplication, etc.

"Rüdiger Gamm (born July 10, 1971) is a German "mental calculator". He
attained his ability to calculate (memorize most of the time) complex
mathematics in his head at the age of 21. As well, he can also speak
backwards in complete sentences and words, and calculate calendars.
Featured on the Discovery Channel show The Real Superhumans, he was
examined by scientist Allan Snyder (Savant Expert) who concluded that
his ability was not a result of Savant Syndrome but connected to
genetics. According to Gamm, anyone can do what he can do. "There is
just a table of numbers to learn then anyone can do it."

I have always been good at understand the abstract nature of
mathematics, but perform rather poorly on basic mental calculation --
it would be a great skill to have and away with a physical calculator;
combined with a developing memory system; dual n-back training (1h
daily); healthy diet, and all other things good. I would throughly
enjoy expediting learning and overall metal capacity and efficiency.

Note: I am having racing thoughts, and am having horribly intense
dreams; they aren't bad, but I sweat, move around, and become physical
exhaustive -- seeing shapes and images if I lay my head down and close
my eyes and allow my mind to wander; often during a transitionary
phase from consciencenss to sleeping.. I don't know what you would
call it. I was in my office today and felt I had a mental and bodily
surge, electrical in nature. I often experience moments when thinking
or analyzing concepts and deriving answers and explications myself,
and get the same sensation as I do when I orgasm. I can even activate
it on demand. Would anyone know what would cause this?

I have noticed this for several years, but not inquired about it.

I am interested myself in mental calculation. You might want to look
into the Trachtenberg system, and check out
http://www.myreckonings.com/Dead_Reckoning/Online/Online_Material.htm

Personally, I've read a book about the Trachtenberg system, but I
haven't practised much beyond mentally squaring two-digit numbers.

The pre-sleep experiences you describe are probably what are called
hypnagogic sensations. http://en.wikipedia.org/wiki/Hypnagogia#Sensory_phenomena

The intense dreams are probably related to n-back's effect on dopamine
receptors, especially if you're doing 1h daily. You might want to
learn lucid dreaming, for general interest and to control nightmares.

Dopamine receptors are also related to the reward system, which might
have to do with the orgasm feelings; I don't know much about this.

i think practice mental math may have some cognitive benefit, like
addition, subtraction, multiplication of two digit numbers under time
constraints

i think squaring two digit numbers may also have benefit and some
limited single/double digit division.

i doubt as much of an effect as dnb training, but nonetheless, some
benefit.


i could be wrong--it is just an opinion.

there are techniques for mental math..........using rounded tens
place, doing the calculation, then adding in the remaining
calculation........there is a guy who wrote a book and did a video
series for greatcourses/teachco/teaching company that shows these
techniques..............

lumosity has some practice we can do for each, but not sure of the
squares.


it would be kinda cool if there was some of those addition/subtraction/
multiplication games that lumosity uses that were free--basically
flash games of things dropping down from the sky, increasing in speed/
difficulty

On a separate note, i have taken an interest in LINGO. I realized
while watching my wife watch the game, that i sucked at it--i am not
good with vocabulary.

so i found some free source that took 40,000 words used from movies
and such, and i separated them into groups of 2, 3, 4, 5, 6, 7, 8, 9,
10, 11, 12 words and sorted by frequency...........obviously the ones
at the top are more accurate (less crap, slang) than the ones at the
bottom, and probly more important anyway since they are used more.


i think there were about 2000 or so legit LINGO words (5 letters)


i was too lazy to clean the lists and i have not practiced
yet................


all i am saying/thinking is that it would be nice to find a way to
'practice' word recall based on the 40000 word list wherein all vowels
are removed or something, some sort of frequency repetition algorithm
is used like in supermemo (sm2 algorithm), and we could improve our
word recall thru active memory processes.


i lack the skills to implement something like that tho.

here was the mental math book:
http://www.amazon.com/Secrets-Mental-Math-Mathemagicians-Calculation/dp/0307338401

not that i am recommending it, but i have seen it online in pdf format
for illegal download

here is the movie version, but probly not worth it just for this since
the book is straightforward:
http://www.teach12.com/tgc/courses/course_detail.aspx?cid=1406


i dont know how to do a research paper, so i did purchase their
writing course with the printed transcripts for review:
http://www.teach12.com/tgc/courses/course_detail.aspx?cid=2133

It would be nice if there was a book of perhaps 100 research papers
utilizing all the major techniques (comparison and contrast, etc) for
social and hard sciences, in addition to research resources (my wife's
university rarely had the research documents--they had to be special
ordered via interlibrary loan or whatever, so it took forever to just
gather 20 or so research documents and then decide on a POV for the
paper--that concept sucks. When i was at UCR back in the old days,
research was pretty easy there--they had floors and floors of bounded
texts of journals, and microfiche--my community college sucked, so i
got a library card from UCR and did my research here and was able to
earn an A in English Literature, for instance)


20+ years later, and first i realize i wasnt a very organized writer
in the first place (intuitive), and second now i have forgotten just
about all i did know.............

[napoleon's_pidgin]

I vouch for the "Secrets of Mental Math: The Mathemagician's Guide to
Lightning Calculation and Amazing Math Tricks" books. It's full of
practical mental math instruction

In the mental division chapter there is an interesting quote that
reminds me of DNB and digit span

"When dividing in your head instead of on paper, you may find it
difficult to remember the parts of the answer as you continue to
calculate. One option, as you've seen, is to say the answer out loud
as you go. But for greater dramatic effect, you may prefer, as I do,
to hold the answer on your fingers and say it all together at the
end...."


This stuff shouldn't be considered "magic tricks". It's incredibly
useful and efficient.
