The Red Menace had laid low for nearly a year before returning this morning to the Firecracker 5K race! 21:16 time, a 6:51/mile, his 2nd best effort ever!.The only disappointment was that the classic pancake breakfast has now been converted into breakfast burrito distribution.

Yesterday the 1st-year Astrophysics majors in Astronomy 9 presented their 2-quarter-long group research projects. This class, started by Ruth Murray-Clay, has been a huge success in slowing the leaky pipeline that drives some out of STEM majors.

Yep, that's what it's been like rooting for Minnesota sports teams in my life! It's quite surreal to have "extended" (2 years, ha!) success!.

The Timberwolves are the first Minnesota-based MLB, NBA, NFL or NHL team to be among the final 4 teams remaining in the playoffs 2 years in a row since the North Stars did so in 1980 & 1981.
