<div dir="ltr">Here's a nice lecture by Carlo Rovelli on his development of Spin Foams with Lee Smolin. Great to see the intro to his lecture by Penrose:<br><br><div><a href="https://livestream.com/oxuni/rovelli/videos/199493556" target="_blank">https://livestream.com/oxuni/rovelli/videos/199493556</a> </div><div><br></div><div>At time 41:33, you can check out how space is defined as the volume around a vertex. Steve Smith and some others have heard me wax incoherently about the potential that spacetime is the dual graph of the spin networks in much the same way a voronoi is a dual to a delaunay graph.</div><div><br></div><div><br></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">_______________________________________________________________________<br><a href="mailto:stephen.guerin@simtable.com" target="_blank">Stephen.Guerin@Simtable.com</a><div>CEO, Simtable <a href="http://www.simtable.com/" target="_blank">http://www.simtable.com</a><br><div>1600 Lena St #D1, Santa Fe, NM 87505<div><div>office: (505)995-0206 <span style="font-size:12.8px">mobile: (505)577-5828</span></div><div><span style="font-size:12.8px">twitter: @simtable</span></div><div><span style="font-size:12.8px"><a href="http://zoom.com/j/5055775828" target="_blank">zoom.com/j/5055775828</a></span></div><div></div></div></div></div></div></div></div></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Apr 15, 2020 at 2:47 PM Marcus Daniels <<a href="mailto:marcus@snoutfarm.com">marcus@snoutfarm.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><a href="https://arxiv.org/abs/gr-qc/9905087" rel="noreferrer" target="_blank">https://arxiv.org/abs/gr-qc/9905087</a><br>

Can you point to what you think Baez was doing that seems similar to what Wolfram's doing?<br>
