- It’s Pi-day today!
- Maybe they were preparing festivities… anyway, lately the number one search term for people coming to Qulog is Pi Song.
- As a result, the stats on that post have gone up from maybe four every day to over yesterday!
- There are seconds in a year (error is less than a percent).
- You can ‘measure’ by repeatedly dropping a needle onto a ruled surface. It’s not a very practical way, but I like it anyway.
- Somewhere in the digits of is my birthday. (But where? I always forget.)
- A circle with diameter 1 has circumference and surace area .
- During a lecture on quantum field theory, Gerard ’t Hooft once joked that he used the ‘small circle approximation’: .
- There are more pi-songs than just the one I wrote about last year.
- Oh, I almost forget: , followed by a
*lot*of digits I don’t remember…

Your birthday (and many other strings of numbers) can be found in pi’s digits via the Pi search page: http://www.angio.net/pi/piquery.html

Regarding yours, the answer this page returns is:

“The string ******** [censored] occurs at position 7,411,604 counting from the first digit after the decimal point. The 3. is not counted.

The string and surrounding digits:

90873298712148346809 ******** 02253004005621775580 [censored again]”

Though censored, there is sufficient information available to retrieve your date of birth…

:-)

Thanks for the censoring!

But is is only Pi-day in the usa, right? ;-)

By the way, surace -> surface.

My favourite fact about Pi is that it’s a transcendental number.

It made my A5 class laugh out loud when I told them about pi day. We, the chemists, also have a day called Mole Day. It’s either on June 2 (6/02) from 10.23 AM to 10.23 PM, or on October 23 (10/23), from 6:02 AM to 6:02 PM.

@ Wilfred: Thanks for pointing out the typo. Yes, it’s only Pi-day in the US, and then only for the nerds who like this sort of thing.

@ Machiel: Mole day… that’s a nice one, too. There must be a lot more possibilities…. day? 1st of May (5th of Jan in the USA), 10:34 or something (maybe 9:26, because that’s 10:(-34)?).

Thanks for the article. This is way of the mark…but I was delighted to know that my sur-name has a day reserved for it. LOL :)

You’re lucky with a name like that!
