Every Day is Pi Day

April 8, 2011

Wowwwwwwwwww!!!!!!

π   π   π

Mathspig is very excited to note that Pi has been in the news this week.

.

.

.

Firstly, in an article titled Pimp My Memory New Scientist, 2nd April, cited Chao Lu’s feat of remembering π to 67,890 places in November 2005.

.

It took Chao (pictured below) 24 hours and 4 minutes to recite the 67,000plus places!!!!!!!!

.

.

If Mathspig was listening I dare say she would have fallen asleep and slammed her snout into the table top at 200kph at about the 300th decimal place.

.

.

But I can’t help wondering what would happen if some one said, Aussie style ‘Nah, mate! You missed one. That 61, 235 place was a 3!!!!!’

π

This is more a feat of memory than maths.

.

Wowwwwww !!!!^2!!!!


Then The New Yorker, 4th April 2011, reported on Pi Day activities in the Facing History School (pictured ), Hell’s Kitchen, NY. (Below random students)


.

Maths teachers held a pi-memorisation day on Pi Day (3/14 in USA, which unfortunately in Australia is written 14/3) offering a new iPod Touch as a prize.

π

.

There was also a pi pie-eating contest and a pi “jeopardy” game.  The Maths teachers all wore Pi Day teachers with names printed on the back such as Karina “The Algorithm” Garcia.

π

 

The winner of the pi-memorisation was a sophomore (Year 10 in Australia), Jason Gil, who recalled 162 digits. Yey!!! Go Jason.

Mathspig urges maths teachers to have a fun maths day. Other subjects have days and events!!! Give maths a big profile in your school. A Pi Day is good. And a pi-memorisation challenge can be lots of fun. Here are three ways to remember Pi.

π

1.Phone No. Method

π

Some students at Facing History School, NY committed  the pi sequence to memory by putting the numbers in blocks of cellphone numbers.

2. Song Method

The Pi sequence can be remembered using a Pi Song.  Here’s a song to recall the first 10 digits.

π


If numbers had a heaven

.

Their God would surely be

,

3.1415

.

92653

π

It is sung to the Mickey Mouse Club Song.

.

.

Here is a more entertaining song called Mathematical Pi Song by 4ACT, which proves that good mathematicians make crap singers.


.

.

3. Piem Method

The third way to memorise the pi sequence is to write a PIEM … or Pi Poem.

π


It can be a crazy poem but each word has the number of letters of the digit to be remembered.

π


eg.

How I want a drink, alcoholic of course, after the heavy chapters involving quantum mechanics.

π

Here’s a piem by Maths pig:

.

Get a grip u maths pyschopath I’m afraid piday fun shidz students painfully.

π


All right, already. Some poetic license is allowed. Tricks such as rhymes and mnemonics like the piem will only help memory if they are witty and apt but you must know what you can get away with.

π

How to study for exams? According to studies reported in New Scientist the best way to learn for an exam is to constantly test your memory. Make it work hard. REcall. REcall. REcall.

π

I’m Mathspig. I didn’t say I would be a nice pig.
