		<description>One time, not too long ago, a nerd from up north traveled down to the outer banks. He lathered his nerdy head with sunscreen, so as not to absorb too much wisdom from the healing power of the southern suns rays. While others frolicked in the ocean&#039;s lapping waves, he sat and dreamed of card catalogs. He occupied his time thinking of particles and spaces, until a sweet small angel beckoned him to come lie down beside her, where she had him read stories and sing songs concerning real matters of consequence which filled his mind and calmed his soul until he, now right with the world again, drifted off to a sound sweet sleep.</description>

		<description>Ha! The last two sentences of the first paragraph were marked with a fake HTML tag marking them as a digression but apparently the website removed/hid that when the comment posted. So I&#039;m not quite as spastic as that sounds!</description>

		<description>Sorry if this HCL was a little more latent than you hoped, hopefully I can slip in before the final gavel.  My internet-accessible times this week got filled up with playing with my beach pictures and pretending to still be at the beach.  :-)  Also, even as late in the morning as it is, it still seems a bit early for straight tequila, which I thought was a necessity for a Meeting of the Outer Banks Cosmological Association, but I&#039;ll do my best without.  When I was about 13, I went through a phase where I was going to me a cosmologist, and Dad constantly told me I was going to be a cosmetologist.  I mention this because I think you said @ Nags Head that I&#039;d spent the past 4 years learning how to be antagonized, but you see, it&#039;s been much longer than that.

Anyway, I don&#039;t disagree that emergence is both interesting and important, and I even sort of like the emergent definition of physics in the next post.  But I don&#039;t quite understand the rest of your argument, so I&#039;m not sure whether to disagree or whether I&#039;m just confused.  My default reaction in this case is, of course, to be argumentative (as I&#039;m sure my brother or husband would be glad to assure you), so here goes.  First, I still don&#039;t really see what this has to do with Zeno&#039;s paradox.  It sort of seems like you&#039;re saying that since we can (at least in a thought experiment) divide any property (e.g. distance, time, energy, mass, etc.) into infinitely smaller bits, so small that no information can really be carried, that that means that any information we can actually understand actually has to be made up of multiple bits and is therefore emergent.  Is that getting somewhere close?  I accidentally made a computer science-y sort of pun there, but it makes me think of another way to phrase what I think you might mean: you can divide a piece of information into 1&#039;s and 0&#039;s and thus have indivisible pieces of information called &quot;bits&quot;, but if you don&#039;t have any context to use for deciphering those bits, there isn&#039;t really any information there.  If that&#039;s what you mean, I think my reaction is that, it&#039;s true that we as humans probably can&#039;t understand things like electrons or quarks or bosons without context, and anyway, what would that even mean, since you don&#039;t get to the point of discussing such things without bringing along mental baggage.  But I don&#039;t think that makes things that are so fundamental as to be beyond our understanding banal, rather beautifully mysterious, maybe in the same way that Zeno&#039;s paradox, or integrals, are.  On the other hand, I decided to become a biophysicist instead of a cosmologist, so maybe that tells you something about where my real interests lie if we&#039;re making a scale from fundamental to emergent.

When&#039;s the next meeting?</description>

		<description>Let me see if I&#039;m getting this straight -- while also angling to become an overwhelming response.  A haiku is emergent from the words, syllables, lines of which it is comprised?

&lt;blockquote&gt;&lt;em&gt;Things emerge from things,
Emergents from emergence:
What whence, which whither?&lt;/em&gt;&lt;/blockquote&gt;</description>

		<description>Thanks for the comment, Adi.  You&#039;re correct about there being no difference between a vertex and a hypervertex: both connect n edges.  The interesting nuance that I was trying to highlight is that there is also no difference between a hypervertex and a hyperedge.  Does that make sense?  Both are structures that connect n structures.  I was proposing just to call them a &quot;hyper&quot; rather than a &quot;hyperedge&quot; or &quot;hypervertex.&quot;  Then one could say that a hyper connects n hypers.

It&#039;s kind of recursive, and it&#039;s not obvious how to draw it (one could, for instance, draw it in a simple 2-D graph).  Other possibilities abound...</description>

		<description>I am researching about this hypergraph with relation to the shortest b-path. I have never heard (although I have thought about the idea) of hypervertex. If a hypervertex connects n hyperedges, wouldn&#039;t it be just a vertex? I mean, a vertex in a standard digraph already connects n edges. So, I don&#039;t think there&#039;s a need to invent hypervertex at all.

The idea that I thought of would be something like this: since hyperedges seem to be a cluster of edges, can there be a cluster of vertices to make a hypervertex?

I know this is an old post, but I am still finding an approximation for the shortest path since it is NP-Complete.</description>
