Meme of two women fighting while a man smokes from a pipe in the background.
The women fighting are labeled “mathematicians defining pi” and “engineers just using 3 because it’s within tolerance”
The man smoking is labeled “astrophysicists” and the pipe is labeled “pi = 1”

Pi = 355/113
38 digits of pie gives youv an error of less then a hydrogen atom in the circumference of the known universe.

From the article for anyone who cares, NASA uses 15 digits (
3.141592653589793) because at Voyagers current distance from earth (~48 billion kilometers) that would give you an accuracy of less than half an inch.
As a retired mechanical engineer, the joke is that we don’t really remember the value of Pi, but we think it’s somewhere around 3. But maybe we should use 4 just to be safe.
In any case, I have to remember 3.14 because one of my Daughters was born on Pi Day. Which, according her, is the second most important day of the year, just right behind Christmas Day, when she was growing up. So when she got into high school that meant that we had to bring enough pie to be served in each of her math classes on that day. (Oddly enough she prefers cheese cake over pie on her Birthday).
Now I’m not saying being born on Pi Day influenced her life any, but she has a PhD in Mech Engineering.
Good news for her. Cheese cake is a pie not a cake.
Not according to her. And I ain’t about to argue the point with her…
This made my day.
Solidifies my preference for pie over cake
It’s called “cheese cake” not “cheese pie” so I don’t think so
Pie is a set filling in a crust. Cake is a sponge with optional glaze or frosting.
Twas a joke
You sound like an involved and caring father. Rock on, dude
as an engineer, a lot of languages (even proprietary ones) have a built-in constant pi variable because it is so ubiquitous - its easier and more readable to use pi than 3…
I’ve also never seen a fellow engineer simplify pi to just 3, although I have seen a rise of memes from people who think they do.
I would slap someone if I saw them try that, it’s unnecessarily sloppy. 3.14 is the default, and trivial to work with if you’re using a calculator (I would also slap someone if I saw them not using a calculator). Unless you just LIKE having all your calculations be off by almost 5%. Then you’ll come back wondering why so many of your parts are out of tolerance.
Electrical engineer. Never used 3. Always 3.14. don’t really get the joke.
I heard once π²=10 is fairly accurate approx and thus g=π²=10 in astrophysics where people thinks in order of magnitude, not value.
But my engineering ass is telling assumptions with larger than 50% difference from actual value may cause issues on order of magnitude if the value is used multiple times and isnt it better be like 5=1/2×10?
That’s because your engineering ass needs things to be physical and sane. Physics is a field for the mentally unwell to sink further into insanity while incoherently scribbling greek letters on every available flat surface.
On a more serious note, yeah you absolutely have to be careful about where you apply really ambitious simplifications like that. There are plenty of mathematical regimes where you can use natural units (this is the term to look up if your interest extends further) and simplify your reference frame by a hell of a lot though. Setting the speed of light to 1 is also a hell of a drug, and brother I’ve got an addiction
I use 3 16/113
You’re a monster. I love it
Only basic math. You can convert Pi even more precise, but I think to 6 decimals is enough.
So this is just an Ai produced meme?
“Everything I don’t like is ai”
Grow up. The imgflip watermark is clearly visible in the meme, and it’s an ancient meme format.
This image is a two-panel meme utilizing a blurry, chaotic photo of individuals seemingly engaged in a mock fight and a separate photo of a person appearing to conduct a science experiment with a small flame, possibly under the influence of poor judgment.
In the left panel, the text “MATHEMATICIANS DEFINING PI” is superimposed over two individuals engaged in a dramatic physical altercation, one holding the other back. A third person, who is uninvolved but present, is labeled “ENGINEERS JUST USING 3 BECAUSE IT’S WITHIN TOLERANCE.” This suggests a hierarchy of concern regarding the numerical precision of π (pi), with mathematicians caring deeply, engineers demonstrating relaxed standards, and general chaos ensuing.
In the right panel, a shirtless person crouches and conducts a questionable experiment involving a lighter and a small pipe. The caption “ASTROPHYSICISTS” is positioned above their head, and below is the phrase “PI = 1.” This implies a level of approximation so extreme it borders on parody, indicating astrophysicists allegedly use such simplifications in the name of cosmic-scale practicality.
The overall composition is an exaggerated commentary on varying standards of numerical precision in different disciplines, presented through low-resolution imagery and humorous juxtaposition.
