Happy π day


Through AutoDesk Labs I have found out that today is the day that since 1988 has been celebrated in honor of the letter PI, a representation of that number that we hate when we are studying. We refer to the number (3.14159 ...), which in dates would be March 14 at 1:59 am with 7 seconds, 254 thousandths of a second and ...

As we know, the origin of this number is the times that the radius can fit in a circle, when we carry trigonometry we are taught to calculate it by means of series, for practical purposes it is enough to say 3.14 O well 3.1428 3.1416

image This brings to mind one of the Guinness Records Winness, which certifies that a Japanese could say 67,890 memory digits of this number in a time that took 24 hours and 4 minutes ... that fit * n!

For this he used a practice called philology, which consists of associating words to numbers based on how many letters he has and learning only the words, to exemplify it we will use part of the poem of Hugo Chavez in his political campaign:

they are going to pee and shit gasoline ...

Let's observe that if we count the number of letters that each word has, we have: 3 1 4 1 5 9, and that is how Japanese could learn that many digits ... the Chinese had nothing to do, well it could have helped me with 22,345 cadastre documents that I have to scan, extract, and associate with registration plates in personal folio; so I cannot give you a Winess award but I can pay you for your memory, because you have to read each document and look for transaction numbers in old print that coincide at some point with numbers listed in the cadastral record.

  1. With all the shame of the world, thanks for the correction friend.

  2. Two things: The first one is that the PI number is 3.1416, or 3.141592. Nothing 3.1428 like you say. That number is the one used by the TopCart (topographical calculation program) to punch you when you have a pirate. You think that you are doing well the conversion between degrees centesimals and radians, and in fact all your azimuths and coordinates appear displaced.

    Secondly, it is not Winness but Guinness.
