Hazelnut spread is one of those things that is much more commonly referred to as the brand name. No one says "Reynolds wrap" they say "aluminum foil". No one says "hazelnut spread", they say Nutella. No one says "resealable sandwich bags", they say ziploc bags.

> No one says "hazelnut spread", they say Nutella. For one thing, Nutella is chocolate flavored. No one would ever even consider calling it "hazelnut spread".

It's both!

I don't know any Semiotics! But, in an effort to drive the conversation, I can be more precise with what I'm trying to say. I'm working with this informal idea that there is always a relationship between the audience and the speaker. That relationship define a shared knowledge space. If I am speaking to a group of my friends and need to refer to my brother the set of identifiers that uniquely conveys his identify to…

There is a lot to unpack in your response, but I guess it’s your use of the term ‘degenerate’ which confuses me. It’s not common in the Semiotic cannon, and so you say it’s not something you’ve studied. From your original comment: “...contextualizes that good as being different from all the others (un)like it.” This is textbook Semiotics. Meaning is not derived from the designation (‘apple’ is the red fruit with the…

It's totally common when talking about quantum states that have identical energies! Which is not helpful at all in this conversation. It's just one of the words in my everyday tool bag and I used it without thinking too deeply.

All that said I just order an intro book on Semiotics. Interest definitely peeked.

There are various people speculating on the economic significance of this solution, which, to me, is rather missing the point. It's like measuring the significance of the excavation of Tutankhamen's† tomb by the tourist revenues of museums. The point of economics is that it keeps us alive so we can do math and also think in other ways; the point of consciousness is not to make money. I don't think there is any econom…

The economy is, and always has been, the society.

I get that your comments are playful, at least in part, but the thing that makes discoveries worthwhile is usually getting them in the hands of mere mortals.

Slightly related: One thing I've learnt in Physics is that there are still a huge number of practical and fundamental problems to be solved. You might expect everything easy will already be done by now but that's just not true. Hence we still manage to write so many papers! In fact many Physicists have too many papers they want to write and not enough time to write them. This was a huge surprise for me coming in to m…

Are there fields like this in computer science where many papers are yet to be writen?

No. But there are things besides money and math. Like photography!

I thought the point of photography was primarily so that you (people, in general, not necessarily just you individually) could look at the photos, i.e., experience them consciously, and secondarily to consciously experience the process of photography itself. But perhaps you have a different reason for considering photography worthwhile, other than the conscious experience of the photographs and of the photography pro…

Is there a way of unconsciously experiencing these things?

Gave me shivers reading it. Beautiful example of the incredible mystery of the human mind. Poof! And the solution materialized. Of course, all the groundwork had been laid. All the neurons primed. Just incredible. And that formula. Damn.

That formula is just a Mathematica dump. If you read the paper, which is unfortunately paywalled, you'll see the result is the solution to a complex system of equations, which are far easier to digest than the result you see there.

This seems to be a version of it: https://arxiv.org/abs/1811.03792

mind-blown by that formula amazing what people think of

It wasn't thought of, it was calculated using a computer algebra system. Such systems are very powerful, but tend to be fairly bad at writing things nicely and simplifying, so they often produce insanely big and complicated formulas.

None that I'm conscious of.

Since they put the paper on the arXiv, any mere mortal with internet access can download and read it, and some of them will find that worthwhile.

The economy is an important part of society, but only part of it.

Nutella though is a sugar-and-palm/vegetable-oil spread, which - probably accidentally - contains traces of hazelnuts, powdered milk and cocoa.

I don't understand the downvoting of the parent here, which is factually correct and worth noting. It's incredibly unhealthy and this is just down to marketing that anybody eats it. You can make really nice chocolate spreads with your own hazelnuts

The needlessly bad-faith "probably accidentally" is factually inaccurate.
