I remember 3.14159. Recently I tried to add an additional 5 or 6 numbers onto it during my spare time. I remembered them for a little while, but now I can't remember them.

I saw this post yesterday and thought; maybe I should look at this pi! Doesn't take that long memorising raw numbers, now I know:Monique said:I don't understand why people waste their time remembering the decimals of Pi, do something productive that will actually be of value!

I add a couple of digits every decade or so. Now in my late 40's, I have 8 or 9 digits memorized.Klockan3 said:I doubt that there is any scientist who knows less than 3.14.
Felipe61 said:must get really old now.. i only remember 3 decimals of pi.
So, you say 3.1?rewebster said:if you remembered 3----would they still be called decimals?
(i just know one decimal of pi)

I don't think I could do it in 15 minutes if I tried right now. And probably not in an hour even - unless I figure out some clever trick to memorize it. In general though, the way I memorize things is by seeing/using them periodically (i.e., through familiarity). I'm terrible at committing to memory by repeated recitation, like I've seen others do, but that's also probably because I have not put much effort into developing that skill.Klockan3 said:I saw this post yesterday and thought; maybe I should look at this pi!

I am sure you know much more digits than that, associated to different things than pi though. I mean 4 digits take ~1 minute to memorize, so the above string should take roughly 15 minutes. Not that much of your life.
The trick is to want to memorize, at least for me. If I don't care I will only remember bits but when I focus I can remember just about anything indefinitely. The problem is of course that you can't just conjure up such focus at will.Gokul43201 said:I don't think I could do it in 15 minutes if I tried right now.

pi-70679 said:I just find that learning pi is a good way to maintain your memory active, plus it's a really good time waster. I found out that now i can remember series of numbers in a lot less time. I just use birthdates, repeating numbers, and my latest, pattern you do with your fingers when you type the keys on the numpad.
As a scientist, I have studied and used Pi extensively in my work. I can confidently recite up to 50 decimals of Pi.
Currently, there is no known limit to how many decimals of Pi can be calculated. With advanced computing technology, Pi has been calculated to over 31 trillion digits.
Pi is considered an irrational number because it cannot be expressed as a simple fraction and its decimal representation never ends or repeats in a pattern. It is an infinitely long and non-repeating number.
Pi is used in various fields such as mathematics, physics, engineering, and even in everyday technology such as GPS and computer graphics. It is a fundamental constant that helps us understand and solve complex problems related to circles and spheres.
Yes, Pi can be used to calculate the circumference of any object that has a circular cross-section, such as cylinders, cones, and spheres. This is because Pi is a constant ratio between a circle's circumference and diameter, and this ratio remains the same for all circles, regardless of their size or shape.
