Do we need endless digits of pi? Alex Dainis explores the significance of pi, an irrational number crucial for relating a circle’s circumference to its diameter, boasting infinite digits. But how often do scientists actually utilize all those digits? She uncovers the truth behind pi's practical applications, revealing insights from NASA's Jet Propulsion Lab on the precision required for interplanetary travel. From separating essential digits to understanding its real-world implications, this video aims to demystify the enigma of pi and its relevance in the realm of mathematics and science.

Do you
really need all this pi? 3.14159265358
97932384626. That's all I have memorized. Pi is an irrational number
used to relate a circle circumference
to its diameter. It has infinite digits. But how often do
scientists actually use all those digits? Never. A scientist for NASA's
Jet Propulsion Lab said that even
for their most accurate calculations, things like
interplanetary travel, you only need to use pi
rounded to the 15th decimal place and you'd only need
about 37 decimal places to very
accurately calculate the circumference
of the universe. Though that doesn't
stop people from memorizing way
more than that. The record currently stands at 70,000 memorized digits, which took
the person 10 hours to recite.
But for your everyday purposes,
3.14 is probably fine. And you really only need
a handful more digits for your most accurate
engineering applications. But how much pie
is too much pie? The limit does not exist.

As pointed out in the Simpsons by Dr. Frink, in order to get everyone's attention... ahem ... "Pi is exactly 3!". Now that I have your attention...
The was so surprising. I thought I was the only person that memorized until when the easy pattern stopped after 626.
Computer scientists use more than 37 decimal places for generating pseudo random bit 🐥
I feel like, given these circumstances, that 42 digits of pi is the perfect amount of digits to round to/memorize.
34, is still insanely precise.
10 hours? His ride could’ve dropped him off went to work n picked him up wit time to spare listening to the last digits
Two comments One: 1/3 has infinite digits too. B: 355/113 is easy to remember.
I believe only 60 digits are necessary to calculate the size of the observable universe to the precision of a plank length. (And thus any more digits than that has precision that is beyond physical meaning) only being relevant in the world of math.
Cool 🙂 but please, say "visible universe". It's obvious when you do know ppl tend to omit that "visible" part. But very confusing when you don't
Nah, I'm a dumb dumb. I prefer my 3.14 and nothing else. But the equation for eating pie is N+1. Where "N" equals the current amount.
I only understand: how much pie is too much pi... No limit exists...
Cheesecake is my favorite π
3.14159 just rolls off the tongue better, sound so clean, at just 3.14 your still waiting for more
Aaah, that pecan pie oie looks so good!
When I do math on paper, pi = 3.14159
Never too much Pi....or pie. 😉
Happy pi day everyone!!!
I have found a limit to foof pie, that is when 30 minutes after your collegues complain about your complaining.
Who is this person? Is this her channel?
