Q&A for How to Memorize Pi

No. The numbers representing pi never repeat themselves in a particular sequence. This is true of any irrational number.

Pi was originally calculated by comparing the length of the circumference of a circle with the length of its diameter.

There is no precise answer to that question, because computers have calculated trillions of digits for pi with no apparent end.

No. Since pi is an irrational number, it goes on forever. You can try to memorize as much as you can though!

The world record is held by Suresh Kumar Sharma, a kid in India, who had memorized 70,030 digits and recited them in 17 hours and 14 minutes in October 2015.

Maybe noon, when you're brain has woken up and is working properly. At night your brain gets tired and stressed as you long for sleep.

First you need to make sure you're comfortable with remembering more than what you can. Don't stress yourself out.

Take a reliable source. Split the number into sections, and memorize each section separately. Once you have them all memorized, put them together, slowly.

Use the Phineas and Ferb excerpt where the mom goes crazy and sees three performing pies singing "3.141592" over and over and then says Pi! Then use the song method.

It depends. Many people just remember 10-15 digits, but some people have memorized dozens or even hundreds.

It does take more mental effort to translate it, but the actual translation method is easy enough to remember, and some people find it much easier to remember poetry or phone numbers than just strings of digits. For those people, it would take less effort to translate pi into a poem, remember that, then translate it back when they want to say pi.

Nothing works better than repetition. Just keep repeating as many digits as you can, and gradually add more digits as you master them.

No. The digits of pi are completely random and unpredictable.

Just go over it a few times. Singing it is a good idea. I'm memorizing them right now. Doing them before bed (but don't be too tired) is a good idea because if you sleep with it, you will most likely remember it in the morning.

Using formulas. Lots are very easy to calculate on a computer.

Pi is a non-ending decimal number. There seems to be literally no end to it. The latest computer-generated versions of pi run into the trillions of digits to the right of the decimal point. So the answer to your question is "no one knows!"

Yes, if you're an extremely good memorizer. Most people would find that very difficult.

It depends on how sharp your memory is. Search "Pi" in Google to memorize faster!

Pi is irrational because 1) it cannot be described as a fraction and 2) it cannot be marked on a number line. Any number that does not belong to these two categories are irrational.

The octillionth digit of pi is 3. What's after that... scientists are doing their best to figure out as many numbers as they can.

She has memorized a lot. I think she may have grouped digits together, or started with a song. You should start with those methods.

That is a lot of pi. If you still want to memorize more, than add a few digits at a time now. Add two digits every day. If your brain can't hold anymore, than pause a day. Don't make it feel like a responsibility.

I memorized around sixty, and the best way in my opinion is search up some pi songs. My friend memorized 122 digits, and we both started with the pi song! You can search the song up on YouTube if you would like.

Pi is an irrational number. That is why it is infinite. Although there is no "proof", as far as we know, it is infinite. It's like there is no "proof" that numbers go on forever, we know that they do.

You can search on your preferred search engine "first one million digits of pi." That should be enough digits for a start!

It depends on how much effort. I know someone who memorized 122 in a year and a half, but I only memorized about sixty at the same time. I think you can memorize 100 in total in about a month if you tried, because you already know 75-80.

It is possible to use programs such as Python to calculate pi.

Yes. Though pi continues forever, it starts with 3.14, so 3.15 is greater than pi.

It's for calculating the circumference and area of a circle. Basically if you get the circumference of a circle and divide it by the diameter of the same circle, you will always get pi. The formula of the circumference of a circle is 2 x pi x r or pi x d where the r is the radius (half of the diameter) and d is the diameter. The formula of the area of a circle is pi x r squared (r x r) where r is the radius (half of the diameter).

Pi is the ratio (approximately 3.14 : 1) between a circle's circumference and its diameter. It is used in many scientific applications.
