What I don't understand is why does N have to be related to different gauge fields. Why couldn't it be N electrons? Or a mixture of 2, 3, etc of cherges, N in total?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-22973357.post-27620815892924823932007-10-24T08:42:00.000-04:002007-10-24T08:42:00.000-04:00Hi Coin:I guess it depends on what you organize a ...Hi Coin:<BR/><BR/>I guess it depends on what you organize a workshop for. If you just want to get people together to reach a critical brain mass, then it really doesn't matter what exactly they talk about. If you want - as is the purpose of my workshop - have different people working on related things to get interested in what the others are/have been doing so there is hopefully some kind of Sabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-11657686979357834612007-10-23T21:00:00.000-04:002007-10-23T21:00:00.000-04:00Sorry, I was joking about the location part. Certa...Sorry, I was joking about the location part. Certainly it is intensely annoying to go to all the trouble of attending a conference, only to hear that same old boring talk about completely irrelevant stuff, I fully agree. But it is also annoying to find, as I did when I went to a conference in Paris, that a lot of people went just so that they could visit Paris.

I wasn't joking when I wrote the above, I really find it annoying if you go to a workshop on topic X but people talk about topics A,B,C,D instead, just because they like it better or it's a talk they presently have on their laptop.

The other thing you could do is to locate the workshop in some place which nobody likes, so as to eliminate the people who are just there for a holiday.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-22973357.post-88574564429436727112007-10-22T18:35:00.000-04:002007-10-22T18:35:00.000-04:00Great post, Bee, I enjoyed very much reading it!

A movie of unitary time evolution would be indistinguishable running forwards or backwards; but black hole evaporation is supposed to conserve information (and thus the process is in some way reversible) and yet the forwards and backwards running of the movie are distinguishable.Arunhttps://www.blogger.com/profile/03451666670728177970noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-29917420910445521162007-10-22T01:29:00.000-04:002007-10-22T01:29:00.000-04:00dude! thanks for the summaries of the talks. i fel...dude! thanks for the summaries of the talks. i felt bad that this conference was out of the question for me. but now i feel like i had front row tickets :)Chanda @ Disordered Cosmoshttps://www.blogger.com/profile/11462022695342468789noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-34287481608325801662007-10-21T21:25:00.000-04:002007-10-21T21:25:00.000-04:00"What that has to do with the arrow of time howeve..."What that has to do with the arrow of time however, I honestly don't know."<BR/><BR/>Haha!
