Welcome to The Re/Cap Podcast with Ellis Malmgren! This week’s ‘cappenings:

• The queen of seafloor mapping circa the 1950s

• Uncrewed autonomous ocean drones do work

• Is ConTech adoption as easy as 3 steps?

• AI & LiDAR are like a seatbelt for pedestrians and cyclists

• Say awe for dentalgrammetry

• An AEC Error of the Week so catastrophic, load bearing analysis was never the same
