π knows how long it is, yet π still didn’t say “no, after you, you’ll take up a second of my time, but I’ll take up ALL of your time”.
π here is a mindless and inconsiderate jerk.
Being courteous [Off the Mark]

I mean, duh? He’s irrational. ¯\_(ツ)_/¯

doesn’t have to be pi, maybe it’s just 3.1415 :)

Great, but why is 6’s name Sharon? lol
spicytuna62@lemmy.world 5 months ago
Because she’s Sharon the road.

I don’t know, 7 is a bit of a cannibal. π just is a little in the way

It’s OK not to know pi and it would also be OK not to get the joke :)

You should never give up your right of way under the guise of being courteous. It’s unsafe for everyone, and even the best scenario it still causes frustration to all drivers involved.
Dont be polite, be predictable. And thst means taking the right of way when it’s your turn!
6 deserves what they got.

From memory. If I made any error, it had to be a typo.

over_clox@lemmy.world 5 months ago
I’m gonna absolutely take your word on that haha!
I memorized the first 50 digits when I was only 10 years old. They weren’t even teaching that to us at that age, I was learning trigonometry on my own from books my dad found for me.
bstix@feddit.dk 5 months ago
Yeah what a typo. The exact number is : π
I’m procrastinating a bit here so you can skip the rest of the post - unless you’re bored too.
It’s only when you have to actually draw something that you need to plot in an approximation of π with however many decimals are necessary, and only then depending on the accuracy of your tools.
In a lot of math it pays off to save it for later and eliminate it from the equation on both sides or at least only do it once.
And even then it’s futile. In most construction cases, it’s probably better to construct the π physically using a compass, even if it means constructing a compass first.
Let’s step back. For straight lines, people say “measure twice, cut once”, but in reality you also hardly ever need to measure anything in any kind of unit at all. For instance, if you need two boards of equal length, you don’t need to make a measurement at all. Just put them on top of each other and saw both pieces at once. They’ll be more identical than any attempt to measure and cut both pieces individually. Or if you want all your terrace boards to end neatly, don’t even measure them. Just place them all and cut one straight line through the excess at the end. Copying a length of undetermined length is as easy as to place stuff next to each other and cut. “The length of some board” is just as good of a unit as anything else right?
The same kind of ideas also exist for trigonometry, but this might take a little more abstract thinking. Let us make an angle. Instead of measuring or calculating, you just place two sides of your folding ruler against the object and you can copy that exact angle. This can obviously be turned around and create the opposite angle and those kind of tricks.
So let’s say we don’t know the angle or have anything to copy from at all. Pythagoras is easy to construct. It’s as simple as putting stuff up with a 3/4/5 and there’s the right 90° angle. Using a compass we can also easily construct 60° or multiples or fractions of it. We do not ever need a specific angle that isn’t already a factor in or of 60 or 90. Want the gutters to drain? One end goes above the other. As easy as that. Want two sides to meet? Just lay down a straight line between the two.
Take a look at this which appears to be a mathematical work of wonder. I am willing to bet that they didn’t calculate a god damn thing with any amount of digits. It’s all made by using a (large) compass or “rig” as it is called when you attach two pieces of wood to make a compass.
Anyway. I don’t mean to put down to your skill of memorisation. I admire it, and I can’t do that.
If you have any interest in applied trigonometry, I can highly recommend the app: euclidea (android). I honestly think I learned more from playing this game than from any math class I ever took.
over_clox@lemmy.world 5 months ago
That Euclidea game is pretty neat actually. Too bad your link didn’t and won’t work for me though, I’m not signed into Google, so the Play Store doesn’t work for me.
But I found it on APKPure Store haha!

You must have installed my gutters because while one side is higher than the other, they never considered how level it was, because the fucker never drains completely
Bishma@discuss.tchncs.de 5 months ago
I’ve always thought the digits of pi have a sort of lyrical quality up to and including the 897, which made it easier to memorize. I manage to remember the 9323, but past that nothing will stick in my long term memory.

That’s about as far as I memorized it. What’s your method? I picture 2 digit numbers on a number line.
over_clox@lemmy.world 5 months ago
I memorized it in 5 digit sections, except for the first 10 digits. The first 10 I memorized as a 6 digit then 4 digit sequence.
