Ah, that's why Lubos didn't criticize this paper on his blog.sbrothy said:Well, Smolin actually cites Lubos in his paper so maybe that's as it should be. :)

And that's why Smolin cited Lubos, to avoid his criticism.

You don't want to turn it off, just turn off the automatic correction. After typing, look for red underlines and click to get suggestions.marcus said:Notice the terms in the abstract related to that verb:
=======
...To illustrate this, we study matrix models with a cubic action, and show how breaking its natural triality symmetry by imposing different compactifications yields particle mechanics, string theory and Chern-Simons theory. These result from compactifying, respectively, one, two and three dimensions...
========
A simple example of a compactification in point-set topology is the "one point compactification of the real line" by adding a point at infinity. The real line ℝ is not compact (a technical term Wikipedia probably has a definition) but with one point added, which takes the role of both plus and minus infinity, it becomes topologically equivalent to the circle.
by the way, try typing "trialities" if your spell checker is like mine it will change it to "trivialities"
do you know how to turn off the spell checker?
This wabbit tends to agree, though he wouldn't be able to make such a cogent argument as yours in the above post, and also he finds LQG closer to being predictive than STQuantomg said:I say to the “Wabbits” of the world that Q-G is simple, effective, speaks with common and familiar words indexed in our dictionaries, and delivers falsifiable physics. Very much worth exploring. Yet I am not dismissing or antagonizing ST or LQG T, I only say to them that the argument that there is nothing else or nothing better out there than their hypotheses holds no more.
This is quite the opposite of an a priori postulation if I understand it correctly. The constancy of c was first observed (and also predicted from Maxwell's equations), not hypothesized - then, taking into account that observation and reconciling classical mechanics with electromagnetism led to SR and the necessity of merging space and time. Nothing arbitrary there.Jimster41 said:but then who could have predicted that defining c as a constant in all inertial frames and adding -t to the theretofore stable and happy euclidean concept - would make things easier.
Perhaps he thought that this purely technical kind of triality contains nothing conceptually deep?john baez said:The surprising thing to me about Smolin's paper on trialities is that he doesn't mention the most famous concept of triality, even though he is discussing matrix models, and the most famous form of triality gives rise to the exceptional Jordan algebra, which Smolin used a while ago to formulate a matrix model.
