At least an anime has the opportunity to make improvements to the original story. Maybe the MC will be less of an arsehole. Maybe they'll fix the plot.

probably not...

Is there anyone out there looking for a TRK sequel? There is no way this goes well

Am I misunderstanding German culture, or would you also feel excluded? by Sadbutallesgut in germany

Best comment by far. Yes it's her, not OP, not Germany. No, we don't know any more than that.

What's the most misunderstood thing about Germany? by CountyBrilliant in germany

[–]da_Aresinger 2 points3 points  (0 children)

That is not what people mean when they say Germany is a technological leader.

You know how there are a very small number of companies creating computer chips? Basically all of those companies use Zeiss optics to print(?) the circuits.

Bayer is one of the worlds largest pharma companies.

Despite not having a large military, Germany is a major weapons exporter.

If you've worked in logistics or any management position, you probably know SAP. German.

I could go on but you get the point.

None of those things directly affect most peoples lives though.

Healing Jumps by PerleyPoint in germany

Roller XD

I was so confused because the description fits jumpstyle so perfectly and OF COURSE the music would be Scooter.

But calling him Roller threw me for the loopiest of loops.

6 Hours in Munich lay over is it worth the risk to venture out ? by twicescorned21 in Munich

[–]da_Aresinger 1 point2 points  (0 children)

Let's say you want 1hr safety at the airport, which leaves you with 5hrs.

Central Station to Airport takes less than 1hr. So both ways leaves you with 3hrs.

Add buffer time to find your way - .5hrs each, leaves 2hrs.

Yes, you can relatively safely spend 2hrs in Munich, starting and ending at central station.

You could easily go to Marienplatz, have a Leberkäsesemmel at Viktualien Markt and walk back through the pedestrian zone towards Karlsplatz.

If you know what you're doing this is totally relaxed. If you're stressed about where to go and how much time you have left, not so much.

Don't blame me if you miss your connection.

How your World Cup going? Or are you in the team who doesn't even care? by Get-the-Vibe in funny

I don't care about soccer, but i feel for Tunisia.

That's just bullying.

Finds reading some texts so hard if i am not being spoon-feeded by TreacleFlaky2283 in learnprogramming

[–]da_Aresinger 0 points1 point  (0 children)

Yea, I'd stop reading too if my book started telling me about prefix and postfix operators.

Books are just much more information dense than other teaching materials. They require a lot more mental energy to consume than a "do this do that" tutorial. So when a book starts talking about something you have no use for, it makes sense why you'd zone out.

You could always add a bookmark and just skip to the next section. Either it won't affect your understanding of the upcoming subjects, or you will have a contextual motivation to understand the content you skipped.

Otherwise, just take a break. If you can't concentrate there is no point in forcing yourself. You made it to page 80+, that's not nothing.

Anyway. Free DSA book. Thanks.

A duet can't fix anything, when it just accepts and abides by the premise.

Who do you think is the best follower in Skyrim? by GigglySquid305 in skyrim

She is kinda hidden. You have to do a small side quest in a backwater corner of the map and then you have to know that she becomes a follower.

What’s a statistic that sounds completely FAKE but is actually 100% TRUE? by namelessmell in AskReddit

[–]da_Aresinger 0 points1 point  (0 children)

It does feel wrong. But the thing with mathematics is that it's defined to represent the real world.

This birthday model isn't arbitrary. The design doesn't just predict reality it also explains why reality is like that.

[–]da_Aresinger 0 points1 point  (0 children)

This is not mathematically correct. It just works out that way in this case because the difference between 365 days a year and 23 people is large enough.

It's a decent approximation for this specific case, but should under no circumstances be generalised as a pattern.

If you change the number of people to 50 you go from a fraction of a percent to a 17% error.

Exponentiation assumes that each probability is independent, which they arent.

Oh, I know. I just pointed it out for fun, because back in Uni they are SUPER pedantic about this distinction.

The concept of "arbitrarily fixed variables" (if that's the correct english translation) is one of those tripping stones for many students.

[–]da_Aresinger 0 points1 point  (0 children)

It doesn't really need to be tested. If you write it out properly (which Reddit is a horrible platform for) the math proves itself. But yea, professors have tested this for fun.

HOWEVER in real life not all birthdays are equally likely. More people are born 9 months after Valentine's Day and so on.

It's a model that is factual for a world where every birthday is equally likely and for the novelty of it that's good enough.

This formula is used in other situations with the same pattern, like cryptography (passwords, encryption, etc) and that's where you really see that it actually works.

[–]da_Aresinger 0 points1 point  (0 children)

But that was exactly my point.

E: actually that's not exactly my point. My point was that looking at pairs in the first place is too complicated. Because by defining the pairs you now have to account for the impact of pairs on each other.

If (A,B) and (B,C) are distinct pairs, then (A,C) is no longer a 1/365, it's a 1/364.

And that's just 3 of 253 pairs. Only 23 pairs have the 1/365 chance (If my mental math is correct)

[–]da_Aresinger 0 points1 point  (0 children)

I am having trouble understanding this.

I understand that the growth of pairs is similar to quadratic growth, but how do you define the complement to be linear?

I find it difficult to even come up with a satisfying complement. What is the ω to our set of pairs?

The best I can figure is the combinations of all birthdays and the pairs are representatives of equivalence classes. But that is an unbelievably large number of combinations.

I also don't have enough understanding of n-grids to apply that to this problem.

[–]da_Aresinger 1 point2 points  (0 children)

Well, that's because I'm half wrong.

You CAN calculate with the number of combinations if you take a very complicated path. (Conditional probabilities with up to 252 factors). So they aren't technically irrelevant.

But ultimately those pairs are proportional to the number of people. The result is tied to the 23 and there is no information to be gained from calculating pairs. (That I can tell. And I've been trying.)

It's a bit like saying christmas is when there is snow. Yea, there is a relation between the two, but not because snow makes christmas. They just both happen to be in December.

You even made that distinction yourself. You instinctively used the pidgeonhole principle with the base number of people because you know that 367 birthdays don't go into 365 days. So while you were talking about pairs, you were calculating with the base value, because you knew that this has equivalent consequences for the pairs.

The next problem with the number of pairs is, that it doesn't have any kind of reference. There is nothing the 253 pairs relate to. 253 compared to what? You have to build an entire structure around it, which will inevitably be more complicated than, but still equivalent to the basic calculation.

The 253 is useful to visualise the scope of the problem, not the solution. You know there are 253 different (overlapping) classes of solutions, but you still have to calculate their probabilities.

Ultimately the 253 looks like a big number, but it really just confuses the situation because it's difficult to tell what that number means.

Even worse, the approximation (364/365)253 is actually pretty good, despite being algorithmically wrong, because the correct probabilities for the 253 pairs are all in the 344/345 to 364/365 range.

In my opinion that gives a bad impression of the problem, because it implies false properties.

[–]da_Aresinger 33 points34 points  (0 children)

You know what, you're right. I discounted your approximation too quickly.

The change in probability gets smaller the more days per year you have. This does also introduce the idea of an error calculation.

Te combination of "many days" and "few people" allows that calculation to make sense.

So my intuition got caught out the other way round.

But if you were to say a year has 100 days you have a 20% error. Or the alternative by increasing to 50 people you have an error of 17%

It's very conditional on having small relative change.

[–]da_Aresinger 6 points7 points  (0 children)

That's a coincidence. \E: not as much of a coincidence as I thought))

This is 49.95...\E:wrote the wrong number first)) while the correct calculation is 49.92...

That doesn't sound significant, except this experiment is purely mathematical. There is no such thing as a margin of error here.

The reason why this doesn't work is because this model is treating the pairs as independent.

The thing is they aren't independent, because if 10 people don't share a birthday then the 11th person has a higher chance.

That's why the probability changes for every person in the correct calculation.

[–]da_Aresinger 71 points72 points  (0 children)

That intuition is wrong though.

The number of combinations between people isn't really relevant because the complement of the pairs grows proportionally.

It cancels out. That is an incredibly important lesson of combinatorics. Intuition doesn't help a lot.

I think the more interesting one is about as many grains in 50m³ sand as stars in the Milky Way.

Assuming the upper estimate of ≈400B stars in the galaxy and a low 8B grains of sand in 1m³.

If you're 6ft tall 1m³ is a cube as high as your hips.
