This morning, while sipping my coffee and glaring half-heartedly at the pile of laundry that refuses to fold itself, I found myself mulling over the notion of time. Not in the grand, philosophical sense, but more like, how does it slip through my fingers so fast? Just yesterday, I think, I spent an ungodly amount of time scrolling through Instagram. You ever just scroll and then suddenly it's dark outside and you're like, how did this happen?
Anyway, I think it was somewhere between thinking about this and half-remembering a conversation about queues and waiting lines that I stumbled quite by accident into this concept called PASTA. No, not the kind you eat – though, wouldn't that be something? – but PASTA as in Poisson Arrivals See Time Averages. And I can't help but wonder... what on earth does that really mean?
So, apparently, this PASTA thing is some kind of theorem in queueing theory. It’s all math-y and very brainiac, and involves like, calculating average waiting times or something. From what I gather, it’s sort of about how if you have things arriving randomly (like, you in a queue), the chances of you seeing the system in its average state are... pretty high. Probably? But why is it called PASTA? Kind of makes me think of carbs, but not complaining.
I started thinking about my own life waiting in lines. Like, should I think of my waiting as some kind of average? One time at the grocery store, I got so annoyed waiting, I switched lines three times and somehow ended up worse off. Did PASTA have something to do with it? Maybe I was seeing the system all wrong. Or maybe I just have bad line-choosing skills.
I read somewhere, I think it was on an online forum, that this PASTA thing means that regardless of when you arrive, the system behaves predictably. But still, every time I choose a line, I swear, I pick the wrong one. So, is PASTA even a thing in real life? Or is it just some comforting math illusion? I don't know.
And how does PASTA even relate to life, if it does at all? Like, can we apply it to other areas? I remember downloading all these time management apps, like, in an effort to organize myself better. Some had timers, some had alarms, but I deleted most of them when they annoyed me more than helped. It always feels like time slips through before you even realize it's gone. Is that average? Is PASTA lurking there too, quietly smirking as my day flies by?
I’m guessing... maybe? Or maybe it’s just another piece of knowledge that floats around in the back of my mind, like a random fact waiting for a true-or-false quiz on theoretical concepts I don't fully understand.
I should probably go fold that laundry, or maybe not. But in the meantime, does this theory mean I should stop overthinking and just trust the process? I don't have a neat answer. Guess that's the thing with time – it just keeps moving whether you get it or not.
