Happy Pi Day

[RalofTyr]

This day is good because it is...(circular reasoning)

[Moose]

Thanks for reminding me. I have to stop at the grocery store on the way home tonight for some ceremonial circumference.

[NEOWatcher]

The local media is all over this one. (Ok; I heard it twice... once a fluke, twice a story?)

One TV station had a reporter that could (and did) recite it to 50 decimal places (funny that they didn't show what he was looking at :think:)

And a radio station with the news guy who recited it to 20 decimals. Yah, Roight. :rolleyes:

did you know Pi went out with Miss Thurd for a while, but he couldn't take how she used to just repeat herself all the time.

I hear they talked about having a kid, but decided three's a crowd.

(BTW, your .sig had me do a bit of a double-take.)

Or a crowd of threes...;)

I have a middle school book that teaches about pi. It's about the Knights of the Round Table with Sir Cumference and Lady Di of Ameter.

As an aside, yesterday I needed to measure a piece of PVC pipe to determine its diameter. I had my 5th grade son measure the circumference with a tape measure and then I asked him how to deduce the diameter, and he thought about it for a second and said "I'm not sure, but I know I need to do something with pi to get the answer." Math has been a struggle with him, but maybe we're finally making a little progress.

All the Math teachers except mine had parties. Our teacher would never give us a whole day off. The days he let us watch October Sky, we had to take tests both days before.
But he did say "If you can tell me all the digits of Pi, I'll give you a passing grade in this class right now."
So I said "But you can't say all the digits of Pi, Pi never ends!"
"Exactly Kai. Just like I'd never pass anybody in March!"

[Frog march]

if you use pi as the number base then all the digits of pi are 1 and 0, ie 10, tell him that next time.

Math has been a struggle with him, but maybe we're finally making a little progress.A good way to proceed from there might be to try all of the options for doing something with π, then look at the answers and let him literally see which one makes sense. For example, if the measured circumference was about 15.42", then adding, subtracting, and multiplying by π would yield 18.56, ±12.28, and 48.44, all of which he could easily see are too large (or negative, while still being too far from zero), while dividing π by 15.42 would yield 0.20, which he could easily see is too small. Only dividing the circumference by π would yield an answer that was anywhere near the right size: 5".

On the other hand, 2*2=10.22012202112111030100...1 which isn't really practical.



1) I think this miight qualify as an entry in the "You know you're a nerd..." thread, since I actually calculated those digits:doh:

[mugaliens]

Am I going in circles? I thought I'd seen this somewhere before...

[Jim]

I send birthday cards to my several nieces and nephews. My calendar has them displayed and I try to send the cards early, so I don't really notice the actual birth dates, so... Okay, that's a weak excuse.

I just noticed that I have a nephew who was born on Pi Day.

[Donnie B.]

Pity the poor Europeans, who have no Pi day. (31/4 does not exist. Nor does day 3 of month 14. There's something irrational about that.)

Let them eat Cake, I say.

...since I actually calculated those digits:doh:

Ok, out of sheer boredome, I have to ask...

Why?

[hhEb09'1]

On the other hand, 2*2=10.22012202112111030100...1 which isn't really practical.4pi = 102.20122021121111030100... comes in handy calculating the surface area of a sphere

[HenrikOlsen]

Ok, out of sheer boredome, I have to ask...

Why?
It's just the kind of slightly silly things I actually take the time doing when a chain of reasoning passes that way.

And for the 5 minutes it took to hack together the perl script that did the real calculations, it was a fun challenge.


I have another one churning in the back of my mind that's definitely harder, inspired by the grafting thread, which I don't really know when/if will get done.

R U 4pi nw?

I'd better add to this thread before the 1 year expiration date (that some have lobbied for).
