'''Rajan Srinivasan Mahadevan''' (born 1957) is an Indian [[mnemonist]].<br />
<br />
== Early life ==<br />
Mahadevan was born in [[Madras]] in 1957 and moved to [[Mangalore]] in 1959. He discovered his ability to memorize numbers at the age of 5 during a party hosted by his family. During the party, Rajan wandered to a parking lot and committed the license plate numbers of every guest's car for recitation later.{{cn|date=October 2018}}<br />
<br />
== Education ==<br />
In 1977, after losing interest in engineering, Mahadevan set to memorize substantial parts of [[pi (mathematical constant)|pi]]. On 5 July 1981, he recited from memory the first 31,811 digits of pi. [[pi (mathematical constant)|pi]].<ref>[http://www.brainyhistory.com/events/1981/july_5_1981_154000.html Rajan Mahadevan recites 31,811 digits of ã from memory 5 July in History<!-- Bot generated title -->]{{dead link|date=April 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> This secured him a place in the 1984 ''[[Guinness Book of World Records]]'', and he has been featured on ''[[Larry King Live]]'' and ''[[Reader's Digest]]''.<ref>{{cite web |url=http://www.undergrad.ahs.uwaterloo.ca/~blstuart/accomplishments.html |title=Archived copy |accessdate=2007-04-17 |url-status=dead |archiveurl=https://web.archive.org/web/20051221103731/http://undergrad.ahs.uwaterloo.ca/~blstuart/accomplishments.html |archivedate=21 December 2005 |df=dmy-all }}</ref><br />
<br />
Mahadevan received his bachelor's degree in psychology in 1984 and his master's degree in clinical psychology from the [[University of Mysore]] in 1986 during his extended participation in memory study. Mahadevan's [[digit span]] was found to be nearly ten times the average; it is estimated that, before the effects of practice, it was 15 digits.{{cn|date=October 2018}}<br />
<br />
Although Mahadevan is adept at remembering numbers, he nevertheless displays only an average memory when it comes to prose passages or geometric shapes.<ref>DAVID R.
