today's odd fact found
Jul. 22nd, 2008 09:24 pmMy log for the day tells me that I've taken plenty of down-time from studies--adding up the breaks gives me 2 hours of "social time" and almost 3.5 of reading (fiction, e-mail, live journal, blogs, etc) (and food too--I read when I eat, but I don't necessarily eat when I read, good thing to, or I'd be round!), just over an hour of "useful tasks", over 8.5 of sleep, and I've still managed almost six hours of uni work so far today. Those six hours saw 1,048 new words written on my thesis, and four new figures/tables.
I also discovered something interesting about one sample that I'd never noticed before. This one has garnets in three sizes "large & elongate" (up to 2.5 mm long), "medium & round" (just under 2 mm diameter) and "timy" (~0.7 mm wide). The medium ones show the sorts of zoning pattern one might expect from garnets in this area, and the tiny one has a composition that is a bit more extreme than the rims of the zoned crystals, which is "normal". However, the large grains are nearly homogeneous, and intermediate in composition between the medium and tiny grains. They are also located over 37 mm away from the other grains. It is always a good idea when dealing with mineral equilibrium questions to only use grains which are very near one another, and this is a good example of why--one thin section, two halves, two very different garnet populations. Good thing I'd used only grains near one another for calculations, I won't have to re-do anything.
There is still a bit of time left in the day--time to go get some exercise, since an astute reader would have noticed the lack of that variable in my report of time spent today. Time to MOVE!
