  • My parents owned and operated a restaurant for 35 years so I grew up hanging at the bar and huffing second hand smoke while watching TGIF. For me, smelling smoke and stale beer is super comforting. Even typing that I realize is incredibly fucked up but it is what it is. I learned a ton of social skills and relating to all ages and walks of life and it has served me well but its a pretty messed up childhood.





  • College professor here: we’ve all seen a major decline in social skills over the last 4+ years, rather sudden and precipitous, so clearly not just the “normal” changes we’d been seeing over the previous two decades. Loss of basic functionality is the most glaring, like students who simply cannot bring themselves to talk to a professor face-to-face, or speak in class, or make a phone call, or make a decision about their own education, etc. etc.

    The most glaring last fall was an entire class of mine that would arrive early and sit in the dark…despite my explaining how to turn on the lights (i.e. the wall switch by the door). When pressed they collectively said they were “afraid they’d get in trouble” for turning on the lights (despite my telling them to do so) and were afraid to “do anything that would draw attention to them” like being the one person to turned on the lights. So next month with my next group of freshmen we’re going to have a talk about basic life skills on day one, starting with turning on the classroom lights when they arrive.


  • I know way too much about the propagation of plasma in fluorescent lighting. When you first hit a fluorescent tube with high voltage you need some cosmic radiation to rip off the first barium ion off the cathode which causes a tiny little lightning strike of plasma that skitters across the inner surface of the tube. Once it makes its way across the length of the tube to the anode you now have a conductive path. This path then grows tremendously until it envelopes the whole cross section starting from the anode and works it’s way back to the cathode until the whole tube is filled with wonderful plasma that makes light when it excites the phosphor coating.
