Gideon Day 17

4/6 today
1 :( D2/1 Journal - I used to live near Magazine St.
2 :( D3/3 Parabolic Section - I looked this up once, but couldn’t remember and just guessed.  I had arc second written down for a bit, but couldn’t come up with the right P.  I did take the time to calculate (on paper) that it was about 3x10^13km long, though.
3 :) D2/2 Sri Lanka
4 :) D1/2 NBA, ABA - Even I knew this somehow.
5 :) D0/0 Offset
6 :) D1/1 It’s a Mad Mad Mad Mad World
