I would however agree that physics needs more philosophers, with some also being physicists. The thing is Garrett himself represents as being such a person, with his philosophy for life not only what guides and drives him, yet more so what lends his life to have meaning. That is being Phil Warnellhttps://www.blogger.com/profile/15671311338712852659noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-26837239103988673432011-01-20T06:41:53.074-05:002011-01-20T06:41:53.074-05:00This comment has been removed by the author.Phil Warnellhttps://www.blogger.com/profile/15671311338712852659noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-11183664254715203252011-01-20T04:24:54.743-05:002011-01-20T04:24:54.743-05:00If you click on the photo of Bee and Stefan's ...If you click on the photo of Bee and Stefan's backs turned, you can almost read the equations.<br /><br />However, if you click again, they enlarge (for Phil Plait: embigginate), and you can clearly read them.<br /><br />There are 5:<br /><br />- Connection<br />- Curvature<br />- Action<br />- two Possibility equations<br /><br />Possibility equations?!
