It's not me, it's you
I've just emerged from roughly three weeks of no successful lab work. My sequencing gels just refused to polymerize, no matter how careful I was in measuring ingredients and mixing. The only reasons I could come up with were: 1) bad chemicals, 2) I am incompetent and/or have gone insane, or 3) poltergeists. We decided that #1 would be the easiest to rule out, so we ordered all new chemicals. Lo and behold, I made a successful gel last week, replete with pretty sequences. Hooray! However, #2 and #3 are still not ruled out.
An old man in a silver SUV stared at me and then waved this morning, while I stood on the platform in my eight layers of outerwear waiting for the train. I looked like the Michelin man. Either he thought he knew me, or his standards are very low.
Giving the first exam of the semester tomorrow. Not too many student questions yet, other than the usual "Do we have to know this? how about this?" The grading is going to be horrific because not only is it a huge class, but it's a 75-minute exam. I'm mentally preparing myself for a very long and tedious week.
Lunar eclipse tonight! Fingers crossed for clear skies!
