Helps kill time at work on slow days. As a WSO we spend 10 of the 12.5 hours on the line without an office to retreat to, so I email myself book pages and read them while there.
Litho is fascinating as I’m sure you can agree and relate to as a photography fan. It’s quite funny to see aperture and focus and depth of field terms and principles used on DSLR’s appear on the line and tech talk.
I’m trying to score a book on lenses and robotics. At night I don’t have many techs to talk to (only support is litho) so I try to talk to all to get info whenever, however I can - yourself including.
