Retired mathematician and engineer. Avid reader, cyclist, teacher, grandfather, and lock picker--having taken up this obsessive hobby in retirement. From rural North Carolina, currently living in Huntsville, Alabama (where Von Braun and others developed the Redstone, Jupiter, Atlas, Saturn, Space Shuttle, and other space launch systems). Worked on several US and Israeli missile defense systems. For some of my lock picking activities, check out my Reddit profile.
