Happy Pi Day!
Posted by Joey on 14 March 2003, 01:00 GMT

In honor of this most nerdy of holidays, I am typing this article on my TI-89 with the assistance of my TI-Keyboard. There are a few pi-related things worth mentioning...

  • If you haven't already, go out and rent the movie Pi. Although it is rated R [in the USA -- Henrik], I saw it when I was 15 and received no ill effects. It is absolutely worth plunking down a few bucks for, unless you have some strange aversion to power drills. (Shhh... don't ruin it!)
  • Since last Pi Day, the record for the most digits of pi calculated was broken. A super-computer cluster in Japan calculated a whopping 1.2411 trillion digits of pi. (Of course, my cluster of Beowulf TI-81's will beat that some day.)
  • Although it has been available since 1999, it's worth mentioning Andreas Wahlin's Pi Training for the TI-89. By using it, I have managed to memorize 133 digits of pi.
  • 99% of girls and English teachers do not care at ALL about Pi Day, and will look upon you unfavorably if you mention it. General rule of thumb: Do not mention Pi Day to anyone unless you wouldn't feel silly telling them that "all your base are belong to us."
  • Nerd holidays are excellent excuses for postponing tests and eating pie during class. At the time of this posting, it isn't yet Pi Day in the U.S., so you've still got plenty of time to run out and buy pies for your math class. DOITGORIGHTNOW!
  • At 1:59PM (and 26 seconds, if you feel the need to be precise), it is advisable to spontaineously recite all of your memorized digits of pi aloud. Do this even if you think pi = 3.1416.
  • Instead of sleeping, spend all night wondering why ln(-1)/i = 4*(.5!)^2 = pi.
  • Keep in mind that being a nerd is a great gift, and that it will pay off in the long run. Word.

Did You Know?

It's Einstein's birthday... on 3/14

Every say happy bday to Albert!

It's not a coincidence...Einstein must have know what pi was to INF decimal places...it's a secret message...

So...who's interested in joining this new occult?

The next official nerd holiday is...... e DAY!!! Whoo Hoo!!! Someone check me, I worked it out to be April 12 (71st day of February if February had that many days, but on a leap year it would be April 11 :p ) Unfortunately, April 12 is a Saturday...

The official time is 12 April 2003, 08:28:18 GMT. Unfortunately, that is 3:30 AM here, but since it IS a weekend, I might be able to stay up. :p

Where can we find e to 200 decimal places, and I don't mean approximating with Y1=(1+1/X)^X...

You can never start preparing too early. :p

The URL above has 100,000 >:)

This URL is the "Top ln(e^10) Reasons e is Better then pi" according to the author... (same site as above):
http://www.mu.org/~doug/
exp/etop10.html

This is e to 2 million:

This is the Google search I used to find this useless (NOT!) junk:
http://www.google.com/search?
q=euler's+number&sourceid=opera&
num=25&ie=utf-8&oe=utf-8

It's time to start cramming and making study programs for this!!!

BTW, is there a constant 'd'? If there is, there can be a d*i*e = die day... <scary music>Who wants to come to my DIE Day party?</scary music> Actually, for it to be possible, it has to be d*i^2*e or it would be an ERR:UNREAL ANS, and you can't have an unreal date, but then that (d*i^2*e) would be negative (unless d is negative), so i would have to be d*i^4*e, but then to make it DIE day, it would need to be (die)^4, but that might be a number that is too large to correlate to a calendar... Sigh... Make it "(die)^4 Hour" or something. :p

e = 1 + 1/1! + 1/2! + 1/3! + 1/4! + 1/5! + ... + 1/n!

Sweetness... I ran it out to 20 with a simple BASIC prog and it matches the built-in e to as many as I can yank out of it... Cool...

Me too! :) prgmE It was only about 7 lines, though :) I didn't upload it because it's so much easier to type e^1.

On the 83+, it's e-ven e-asier: e
There's a e^( 2nd function (on ln( ) and a e 2nd function (on /).

LOL on the 82 you have to type the exponent. Another weird thing about 82 vs. 83/+... in the sequential graphing, the 82 only supports U(n-1). For the TI-83+, you can get any subtext in there that you want. At least it's less typing on the 82. Another weird thing... to do a regression and store it to a Y= value, on the 83+ you do <regression name> [<list>,<list>[,<function>]]
On the 82, you do <regression name> <list>,<list> then goto Y=, scroll to the function you want, and do [VARS] [5] [->] [->] [7]. *cry*

Re: Re: Re: Re: Re: Re: Guess what we have to memorize now!

No, you can't do U(n-3) or U(n-314)... Only U(n-1) or U(n-2) (TI-83+ Graphing Calculator Guidebook, p. 6-3) I tried this:

nMin=1
u(n)=u(n-1
u(nMin)={1}
v(n)=v(n-2
v(nMin)={1,2)
w(n)=w(n-3)
w(nMin)={1,2,3}

I gave ERR:INVALID and pointed to the w(n)=w(n-3).

Aw, darnit, I thought you could. *cry*

Hey, you could do the fibbonachi sequence really easily with the u(n) thing.

It *should* be easy to transform pi-learners to e-learners if it stores a string of numbers: Just change said string and make it say "Learn e" instead of "Learn pi".

*Gets right on it to have the first e-learner posted this year.*

Yup, I saw 'em on the main screen. Good job :) I thought it was you because of the QBASIC folder thing in there (you were talking about that earlier)... and then I saw the author name. :)

I'd just like to point out that the 99% of girls only applies to non-nerds.

As to the reciting Pi, it would take me more than a minute (way more then a second), and would be right in the middle of English class, the Nerdsum of English class=1.

So um yeah. And happy Pi day.

to tell the truth, they just hide it better. Being a nerd isn't seen as a positive thing, and, for some reason or another, female nerds seem better at hiding it.

Of course, male nerds act very odd......remember that Laura something hoax a few years back? lol I think her account's still here;)

Being is nerd is a GOOD thing! Look at the average nerd's GPA compared to the average dumb jock's GPA.

An IQ is only used to estimate the learning POTENTIAL. It is not necessarily how smart you are.

my iq was taken by the school psycolady... it was 176! jesus christ... no wonder i can like 'predict' what someone is gonna say in the end of his/her sentance EVERY SINGLE TIME! it gets annoying
i wonder...
i only remember 3.14159, but that's cause i never tried to learn pi!
hah... my teacher is algebra 1-b.... but... she takes the calc hw i hand in and i get an a anyway :)

Its not that hard if you are around a person for a little bit because your mind automatically anylises (I can't splle either) their speah patterns and behavior...I do the same thing and it drives me nuts because I do it all the time.

I tried to remember pi a long time ago, but I decided to resist the urge to fullfill my nerdyness.
