So many people are having their plans ruined by winter storms today.

  1. The Lufthansa plane is on its way to San Diego, and it might be raining when it lands. I don’t have the right type of gear to take outdoor photographs in the rain.

  2. Today is the AIME II, the second-chance for students to take the American Invitational Mathematics Exam if they were unable to take the AIME on March 6 (which is “most of them” because the organization running the contest was not able to get the qualifying scores to the schools on time). A lot of schools are going to be closed today. The committee is going to allow those students to take the exam tomorrow, raising some of questions about exam security and academic integrity.

  3. Not related to this winter storm: my neighbor reports that the new roof that we got last year might not be living up to expectations. I am hoping that the problem comes down to isolated problems with flashing and not some sort of general roof integrity issue.
