Randi has announced the names of just some of the guest speakers who will be at The Amaz!ng Meeting 6 in June in Las Vegas. They include the usual (stellar) suspects: Penn & Teller, Michael Shermer, Richard Wiseman (a friend of mine seriously confused the two of us, thinking a picture of him on the cover of Skeptic magazine was me!), and Christopher Hitchens. I'll be there too, of course.
The keynote speaker will be my old friend Neil Tyson, perhaps the most famous astronomer alive. He has his own PBS show, has written several books, and is a great and thoughtful speaker (and has a voice to match). If you've seen any astronomy show in the past, oh, three years at least, you've seen him.
There are others who have been invited, or so I hear told, and when I learn more, well, so will you!
