### The Reference Frame: fifth birthday

Exactly five years ago, on October 11th, 2004, 12:08 am Central European Time (i.e. 10/10/04, 6:08 pm Boston Time), this blog began to entertain and enrich some of you, the world, and myself. The first posting was about

Future of physics at KITP,
a conference in Santa Barbara. As you can see, a largely defunct Columbia University blog that has always been hostile to theoretical physics was important to create this weblog as a kind of reaction.

You shouldn't be confused by dozens of other postings that were seemingly posted earlier: the dates were modified whenever I wanted a posting to be identifiable by Google but disappear from the main page of the blog.

The fifth birthday may deserve a pie with five candles. But believe me, you don't want to eat the pie on the picture above. Those thirty years ago, it was made out of plastic: professional photographers don't always enjoy the same degree of integrity as scientists. :-)

I couldn't sleep if I were hiding this detail from you!
