This elaborate calculation was ineffective because once his daughter disconnected her computer to plug in a hair dryer. Thankfully, the work is saved when plugging in an emergency power source for 10 minutes.

Professor Kondo was also forced to remove the computer case and open the cooling fan (worth about $ 17,750 and the machine has a 32 terabyte hard disk) many times because his indoor temperature is up to 40 degrees Celsius in hot summer. most since 1946.

Professor Kondo intends to try to calculate the value of Pi to 10 trillion digits but due to the limitations of the computer, it cannot be completed.

Kondo's wife, Yukiko, complains that computers use a lot of energy on a three-month project and push electricity up to 236 dollars a month.
