What String Theorists do on Saturdays

Over at Asymptopia, Clifford Johnson gives a glimpse into how he spends his weekends.  From last Saturday:

I sat around puzzling over factors of two and minus signs.  Essentially the whole day.  There were a few stops here and there to do a few things, like a quick blog post in the morning over breakfast, think about what I might do during the day, get some laundry started, and so forth, but eventually I got completely pulled back into the matters that had been on my mind all week.

From this Saturday:

Things got worse and worse through the morning, as I realized that many things I so wanted to be right about the next stage of my computation (which perhaps I’ll tell you about one day) were in fact not going to work.  Not even close.
