The Mental Calculation World Cup 2014 was held in Dresden on 10-12
October 2014 at Math
Adventure Land and the University
of Dresden. 39 calculators from 17 countries took part
(selected from 74 persons from 21 countries who applied in the
qualification).
The event started with a welcome reception where George Lane
presented on a modular
checking system for identifying errors in a calculation - and
for correcting them. Willem Bouman was awarded a "Prix d'Excellence"
for factorizing a number that is the product of three 3-digit primes
(a famous challenge that has been solved by Zacharias Dase). And
there was even a world record at the first evening: Wenzel Grüß
(Germany) correctly factorized 20 randomly selected five-digit
numbers in 10:03 minutes.
After taking part in the first part of the competition on Saturday,
the participants had the opportunity to take part in a guided tour
at Math Adventure Land. The day ended with a show event where the
calculators had the possibility to show their best "tricks" to the
museum visitors at Math Adventure Land.
On Sunday morning, part two of the competition was held. Before the
award ceremony, the calculators got a guided tour at the MPS
at Zwinger - one of world's finest collections of antique
mathematical, physical and astronomical instruments.The award
ceremony took place at Zwinger - the residency of the the former
king of Saxony.
