There's one thing they aren't screaming about: how free will is a myth. It's a topic that gets shot down a lot.

That's barely an info dump on the subject. Observe -

Free will is a complicated subject. If there is a divine creation (or simulation or whatever) then then what started the universe was a seed - or rather a set series of circumstances that started everything. Then everything built on that leading to me writing and you reading this.

Free will is a choice - a decision to choose where your decisions come from. Are you truly in control or do you just choose the best possible outcome based on past relevant experiences? Obviously you will live with the consequences, no one's saying you wouldn't ๐Ÿ‘€

Regardless, we're all built on consequences of our past self which'll in turn become your new past self. And from there it'll continue till death. Obviously death itself is complicated and you'll eventually face it. And what happens afterwards is another conversation. But until then you'll make the most of everything you have. Every damn day.

Edit: formating

I browse Windy but don't rely on any of those 4 weather forecasting models: I take the median of predicted temperatures and rainfalls instead. Also, I predict rain only if the median exceeds 1mm, and if it's below that threshold but at least 3 models predict (some) rainfall I predict drizzle. Which is the same approach I had at my previous job, using data of doubtful quality to adjust Holt-Winters and Box-Jenkins models in order to forecast drug sales for Big Pharma.

Kaggle by the way began to demand users engaged on modelling competitions to make PDFs explaining their methodologies after learning some cheaters would just combine results from other competitors.

P.S. - Don't average results from different models unless you are really, really sure of what you're doing. Many times the models take turns on which one will output garbage, and you don't want garbage contaminating your average. By switching to median you avoid the crap they sometimes spit altogether - not to mention it's so simple you don't even need to write numbers on paper or use a pocket calculator.

In vulcano seismology there is this fun little thing called a tremor and its really annoying but also really mysterious as no one knows where it is coming from or what cases it. I've had multiple people try to explain it or I was listenin to talks about it and I have yet to hear solidly overlapping theories. Also not only does the signal look different at every single opportunity (aka every vulcano) that you to look at it, it also hides within a frequency range that is mostly overlapped with random background signal. So to look at it you need to do analzye your seismometers for a directional eigenvalue (not sure if its the correct word or even the only what its just what I'm doing. I'm normally German speaking but what we do is look at the seismometers and whether or nor all or most of the signals are comming from the same direction) so that you can even detect it, meanin just to look at it you already need some statistics.

Not really sure where I'm going with this I just find this concept really really and I'm just once again baffled that we simply do not know about things in science.

Bet you've met a few soldiers and a few too many cops.
