There are no innocent cats, that is the reason why there are no catties

I just updated my answer with more examples but I think you are right with the nickname thing

I mean it only works with nouns that are not ending on vowels and also not every noun works good. But I heard this from people all over Germany. Mostly in a mocking way, like someone was eating too much and complaining about stomach pain:
“Oh, tut dir der Bauchi weh?”

Other commonly used examples I can think of:

• Lurch - Lurchi (amphibian)
• Frisch - Froschi (frog)
• Hund - Hundi (dog)
• Mutter/Vater/Oma/Opa - Mutti/Vati/Omi/Opi (mom, dad, grandma, grandpa)

In German this literally translates to something like “cute sand man”. Because in German you can just add an " I" at the end of any noun to make it sound cute and small. So “Sandi” can be thought of as a kind of diminutive of the noun “Sand”, similar to “Bauchi” from “Bauch” which is stomach. The correct dimunitve of “Bauch” would be “Bäuchlein” but this refers more to the perceived size of the object.

Its about a certain form of reinforced learning, called Temporal Difference Learning:

The calculation is called simple because it follows directly from the definitions above. Simple means more like “follows directly from definition without fancy math tricks”, not " everyone who can read could solve this in 10 minutes".

I think this is also mostly math related, not physics?

I had a good laugh anyway. Good meme

I am quite happy about this as a non-native speaker :)

Wow I never thought about that.

But it is always like this:

let there be any base "b"
That can represent a number by the sum of their positional digits:

number = sum(d_i * b ^ i)
   where i is the position index and d_i is the digit at this position. (note: index starts with 0, from the least digit farthest to the right)

So the (decimal) number 4 in base 4 is then

1×4¹ + 0×4^0 = 10

And (decimal) number 8 in base 8 is

1×8¹ + 0×8^0 = 10

And 10 in base 10:

1×10¹ + 0×10^0 = 10

Please note that Germany has (compared to other EU members) quite strict and company-friendly protesting laws.

Such protests may be even considered as political protest (Politischer Streik) which makes them not illegal per se but could be illegal. https://www.bpb.de/themen/medien-journalismus/netzdebatte/219308/ein-bisschen-verboten-politischer-streik/
