Anantapur boy on way to Guinness
Anantapur: M Hari Prasad, a prodigious wizard of numbers, will multiply
two eight digit numbers in eight seconds in an attempt to find a place
in the Guinness Book of World Records. He will demonstrate his wizardy
at the Indian Institute of Science, Bangalore on October 30.
Son of an RTC conductor M Mohana Krishna, the prodigy received
guidelines for calendar and mathematics calculation of the square root
of a six-digit number from the Guinness correspondence editor Armanda
Talking to Deccan Chronicle, Hari stated that he would set a new record
in mathematics by breaking the record created by John Conway, who had
multiplied two six digit numbers in 10 seconds. "I am going to multiply
two eight digit numbers in a record eight seconds," the prodigy said.
Dr C R Praneshachar, Department of Mathematics, IISc, Bangalore and C E
Beni Madhavan, Head of the Department, Computer Science and automation,
IISc, Bangalore, would be the authenticators for Hari's record-breaking
demonstration in Bangalore.
The Guinness publications, in their letter to Hari, stated that the
record for mathematics calculation of the square root of a six digit
number set by an individual was the square root of a six digit number to
eight significant numbers.
If done on paper, the calculation takes at least an hour. The
publication company also stated that the authentification should be done
by two reputed members in the community. Hari Prasad had demonstrated
his talent at several shows, including at the National Science Fair in
He was hailed as another Srinivasa Ramanujam. The prodigy completed his
intermediate from Sai Baba National Junior College and is planning to
join a B Tech course. Barring encouragement from his near and dear, the
State government is yet to recognise his talent.
"English is my main draw back. I stand first in all other subjects," the
boy told this reporter. "I have no special talents. It is because of the
encouragement from my father that I am able to perform this. There is an
untapped talent in abundance in our schools and colleges," he said.
Hailing from Kadiri, Hari Prasad's father Mohan Krishna is the guiding
spirit behind his extraordinary talent.
"Most of my income is spent on books for the boy. I had to abandon
studies due to family problems. He will definitely break the Guinness
record," the father said confidently.

[M. Hari Prasad correctly calculated in one minute the days on which 12 random calendar dates fell, at the Indian Institute of Science, Bangalore, India, on October 30, 1999.]
A 20-year-old M. Hari Prasad set three Guinness World Records on October 30, 1999, at the Department of Mathematics, Indian Institute of Science, Bangalore, India. The Indian Institute of Science is a world-renowned organization; although their basic function is learning, they have encouraged the mental calculation skills of Hari Prasad and acted as judges and co-coordinators on the day.
The three records set by Prasad were calculating the square rot of a six-digit number to eight significant places, multiplying two eight-digit numbers, and calculating calendar dates. Prasad was given a 10 to 15 minute break between the three tasks. When calculating calendar dates, Prasad was given 10 sets of 25 dates (between 1601 A.D. and 2100 A.D.) and asked to write down the corresponding weekdays without the use of a calculator or computer.
Hari Prasad was born August 20, 1982, and is currently a B.Tech (Computer Science) student at NARAYANA ENGINEERING COLLEGE, NELLORE, Andhra Pradesh, India. His hobbies include reading mathematical books and searching numbers. Hari Prasad's ambition is to become a noted scientist in numbers theory.
On behalf of M. Hari Prasad, Apollo Quest requests the philanthropic people in the Scientific World to sponsor Hari Prasad's future.
Parents M. Mohan Krishna and M. Ramakrishnamma have only one thing to say, "We are proud of our son".

Fastest Six Digit Square Root Calculation
M Hari Prasad correctly calculated the square root of a six digit number in 1 minute 3.8 seconds at the Indian Institute of Science, Bangalore, India, on October 30, 1999. Without the use of a calculator or computer he worked out the square root of 732,915 as 856.1045496. He also made two other successful mathematical attempts - most calender dates calculated in a minute and the fastest time to multiply two eight digit numbers.
Comment by Oleg Stepanov: On this place you can find video what show how
Hari Prasad calculate 12 calendar dates on one minute, but voise told that
we looks extracting root.
