Isomorphic

@JohnRennie Can you find the links in that chat or should I repost them?

John Rennie

6:01 PM

@Isomorphic I had a look, but I find it hard to get excited about questions that are two years old. just keeping on top of the current review queues is hard enough without adding two year old questions to them.

Bernard Meurer

@0celo7 He's weird

But now the question is then, what dictates which path is seen for each observer in the spacetime?

The ideal type 3 time travel model should be able to produce the effect of "changing history due to stuff done by the observers", but BST, many worlds interpretation, deutsch model etc. does not provide a way to select between the many branches that depends on what happened at the branching points (where the observers will perform/not perform the history altering act), thus you simply cannot predict the evolution at the future light cone of the branching points (having said that I know almost…

@JohnRennie I am giving you another opportunity to do what you're saying, why aren't you using it?

The hardest thing in formulating a type 3 model is you need to somehow recover both the free will of the time travellers while at the same time the theory need to be predictive (that is, it need to have some kind of determinism)

One of the plot elements of type 3 time travel that is never explained in the global view of the story is what happens to the non time travellers when the history change took place, and how is it relative to the observers

I.e. what other people see when anyone other than the protagonist changes history. All type 3 plots in the media we have so far only focus on th…

@BernardMeurer They are salty because I voted to close their question.

@Isomorphic I have never met you, I have no idea who you are and I certainly have no personal vendetta against you. I voted to close your question because it seemed to me to be of no great value to the site.

@Isomorphic whether a question is valuable to the site is always a judgement call. It's impossible to make hard and fast rules for it.

One of the popular Kronecker delta and Levi-Cevita identities reads $$\epsilon_{ijk}\epsilon_{ilm}=\delta_{jl}\delta_{km}-\delta_{kl}\delta_{jm}.$$ Now, is there an intuition or mnemonic that you use, that can help one learn these or similar mathematical identities more easily?

John Rennie

@Isomorphic And looking at the What is “a vector of SO(n)SO(n)”? question I also think that's quite a good question because it has physical relevance. In particular I like David's answer to it.

Isomorphic

@JohnRennie You want me to throw some more questions your way, that you can judge?

@JohnRennie Answer only comes after a question isn't voted to close before it is answered. I hope you're familiar with the working of the site

@JohnRennie So, your logic of not voting to close the question after a certain lies there is flawed

John Rennie

@Isomorphic you seem to be taking this as a personal insult, and it isn't. I don't think your question is bad or stupid or whatever, it just isn't valuable for this site.

Isomorphic

@JohnRennie The time when those questions were asked, were you around on SE?

@JohnRennie If you don't mind me asking, what is your age?

Secret

@JohnRennie @ACuriousMind @Isomorphic(?)
IMO, the questions that concerns SO(n) SU(n) are often tied to or are themselves a physical quantity thus they can be considered not purely mathematics.

However I think I am at loss about the Kronecker questions, because all of them (including the flame wave question) concerns about the properties of Kronecker deltas and levia citiva symbols, and there's little mentioning of the physics that need the questions to be solved, thus they do look kinda mathematical to me

I wouldn't be surprised if active research would already today happen into this direction.

So, what is a hamiltonian?

0celo7

@ACuriousMind Oh, so the compact vertical cohomology is a variant of dR cohomology where the forms are compact in the "fiber direction."

For $K\subset M$ compact, we demand that $\mathrm{supp}(\omega)\cap\pi^{-1}(K)$ is compact.

Slereah

A Hamiltonian is some hermitian operator

That generates time evolution

Where $\omega\in\Omega(E)$, of course.

@Secret I actually pondered that too. I don't know if you've ever heard of steins;gate but in there, and pretty much any other time travel story, the other worldlines that the protagonists leave end up being forgotten. Though, in this example, they decide that the other world lines merge with the current world lines and fragmentary memories are stored in the people of the merged world line of both world lines. But, this is very vague and would need further elaboration.

@secret Actually, it seems pretty precise. Say you are on world line $A$. If you changed an event in time such that $A$ becomes world line $B$, the two merge to form $B$ so it's like 'hopping' world lines. You're of course, erasing history in a sense that (depending on if you allow memories of world line $A$ to exist in $B$) you are erasing $B$ from existence.

Haruhi Suzumaya's $\alpha,\beta$ timelines work somewhat like attractor fields in Steins gate, with a scrambling of memories and even events in both timelines when they merged again. Originally, my Time Sheet Model (TSM) have incorporate that effect because who said you cannot have a ripple effect that is a segment of a worldline?

(But again that TSM model failed me thus we are not going to discuss it further)

The scrambling of memories used by these authors are also random at best, and still there isn't much about how these memories came to be and continue to evolve in time when the time…

The Blueprint

The Blueprint is the sixth studio album by American rapper Jay-Z, released on September 11, 2001, on Roc-A-Fella Records in the United States. Its release was set a week earlier than initially planned in order to combat bootlegging. Recording sessions for the album took place during 2001 at Manhattan Center Studios and Baseline Studios in New York City. Contrasting the radio-friendly sound of Jay-Z's previous work, The Blueprint features soul-based sampling and production handled primarily by Kanye West and Just Blaze. At the time of the album's recording, Jay-Z was awaiting two criminal trials...

Slereah

"It's fairly obvious that you can't metrize a non-Hausdorff manifold. What's not quite so obvious is that it's difficult to even pseudometrize it. I was thinking that you can put a pseudometric on the "real line with two origins" by letting the distance between the two origins equal zero. However, there is a very easy theorem which says that any pseudometric (i.e. a metric which does not require equality of two points if their distance equals zero) must be a metric if the topology is T0.

But every locally Cartesian space is T1, which implies T0. Therefore every non-Hausdorff locally Cartesian space is non-metrizable and also non-pseudometrizable. (I'm assuming that the set contains more than one point!)"

@secret I don't know what you mean by type 3 models. care to elaborate? As for the apparent randomness of memories crossing over world-lines, I think you might need answers for much deeper questions for this to be easily determinable.

I think it'd be similar to adding random memories to a human's brain that did not form by themselves (synthetic memories?). The actual mechanism through which this happens (in merging world lines) I can't see easily.
