Scientific American article[edit]

The February 2007 issue of Scientific American on page 24 included a one page article discussing causal dynamical triangulation. While the science is a bit over my head, it does seem to present some additional information about the theory and its possible advantages over other theories such as string theory and loop quantum gravity. Perhaps an interested editor would care to review the SA article and add appropriate information from it to this Wiki stub? Dugwiki 20:18, 12 January 2007 (UTC)

Yes - I read that article, and some of the related sources, as well. John Baez devoted a fair amount of his talk at Loops 2005 to CDT and also extols the advantages of this approach. I will probably take some time to re-work this topic, as it is indeed an exciting new approach to Quantum Gravity. I'm trying to get a grasp on it myself, and I think I'm fairly close to a conversant understanding. Of course, I'll be including some of what's covered in Mark Alpert's SA article.

I am happy to report that Jan Ambjorn, the theory's primary author, has agreed to answer questions about CDT and review my summary of the topic for the wiki. Expect to see something more in the article section, very soon. JonathanD 02:41, 18 March 2007 (UTC)

The title was changed to Causal dynamical triangulation, as that is the proper name for the theory, as used by all the experts who refer to this subject (notably its framers). I went ahead and moved it first, and will probably merge with Discrete Lorentzian gravity on the morrow. Waiting 8 hours (or so) should insure there will be no complications from bad re-directs.

Still hoping to merge[edit]

My plans are to move material from Discrete Lorentzian QG to Derivation segment of article. I wanted to clean things up here first, and assure there were no obvius errors. Hopefully, I'll get a chance to merge things later today, or tomorrow. JonathanD 17:21, 23 March 2007 (UTC)


Neutrality[edit]

"The Loops '05 conference, hosted by many loop quantum gravity theorists, included several presentations which discussed CDT in great depth, and revealed it to be a pivotal insight for theorists." This sounds quite biased to me... the "in great depth" is out of place, and "pivotal" must surely be removed or at least very well justified, given that this approach is not currently mainstream? --mcld (talk) 10:23, 23 March 2009 (UTC)

And of course the notion of a pivot, in this context, rather makes one's head spin...

I'm going to take some of the hype out of this article in about a week, and mark missing references. About the only think I like is that there is that it attempts to say what CDT in terms that anyone can understand, which should be a minimum requirement for a technical article. CDT deserves much better; I wish I knew enough to do a thorough job cleaning this up. —Preceding unsigned comment added by 216.236.134.75 (talk) 15:15, 30 March 2011 (UTC)

Link to Scientific American[edit]

In the first paragraph there is a clickable link to "Scientific American," and clicking on it informs us that "Scientific American (informally abbreviated SciAm) is an American popular science magazine."

Wonderful! I'm sure this is information everyone who came to this page wanted to know.

That would help us all understand how it could have a particular page, which, however, is not linked...
