First,

*In Memoriam*....:

In honor of Sally Ride, who would've turned 64 a few days ago (born the same year as myself!) and Grant Wiggins, who's sudden death this week at ~65 stunned many educators who he touched and influenced (I didn't know him, but surely admired his passion... and passion for what you do in life is what it's all about isn't it!).

....now on to this week's diverse assortment of links:

**1)**On the 5-year anniversary of Martin Gardner's death, Colm Mulcahy paused to contemplate what he wishes he would've asked Martin, but never did (LOTS of links in this piece also):

**BONUS!**1) The subject of human longevity doesn't usually much interest me, but did enjoy this segment on the topic from last week's

Hope everyone finds some interesting things here you missed, and have a great weekend.
