      Yes, I think it's a great idea for wall decoration!

      Kind of strange that one can miss things like that!
      I think I look around quite a bit "downtown" and this I've missed completly!
      Nice!

      I was very surprised, too. You've seen the Fibonacci numbers on the other side of the building?

      Those were the only ones I've seen - π I've missed completely. Should go have a look at it.

      Passing by there a lot. Never seen this before, have be to more allert when I'm walking the town. Nice pic BTW!

      I usually look down a lot more than up. A wide-brimmed hat, progressive glasses, and a fascination with what's littering the ground will do that to you. But I'm learning that it pays to look up now and then.

      Pi has now been calculated to about 10^12 decimal places. That means you need about the biggest disk drive available just to hold it! The record for human memorizing pi is about the same as it was calculated to in 1960, but the computers are getting ahead so much now that a person cannot even recite it all let alone remember it.

      Wow, this is only 260 places…
      So, how much of the city would 10^12 decimal places of pi cover?

      it looks like this pi here is approximately 10 digits by 5 rows, or 50 digits per square meter. now i don't know how big this building is, but it looks about 5 or 6 stories tall, so let's suppose it's 20m x 20m x 20m. with 5 sides (including the roof) visible, that gives us 400x5 = 2000 sq m of surface area. that means we could fit about 50x2000 = 100,000 digits on this building. so we will need 10 million of these buildings, or a smaller font. :-)

    10. Eva the Weaver 88 months ago | reply

      No, no. Not a smaller font.
      I think it's easier to find out the human population of a city than to find out the number of buildings. Gothenburg is only about half a million people… but how many persons should one estimate for one building???

    11. mag3737 88 months ago | reply

      many times more than 1/20th of a person per building, i reckon, which is what you'd need for 10 million buildings.

    12. Eva the Weaver 88 months ago | reply

      Oh, I was thinking more in line of how many Gothenburgs would you need - and that wouldn't be just 20.

      Great find!

      Seen in Renaissance Man (or Woman) group.

    14. Eva the Weaver 88 months ago | reply

      …because someone had a great idea!

    15. mag3737 10 months ago | reply

      I wonder if 260 is significant to the artist, or just what would conveniently fit given the size of lettering they chose.

    16. Eva the Weaver 10 months ago | reply

      Ten digits to a row (pretty conventional) and the height is what fits the available space - that's my guess
