Aside from the cheapo badge/figure base I grabbed on the way out the door, I'm practically cosplaying ToS Trek without having to do anything special. I did make sure to wear a blue shirt rather than red (I don't own a solid-color yellow or gold shirt, but I'm more science section anyway), I'm already wearing black pants and shoes this time of year. I have a flip-open communicator at one hip, and have a portable computer in my pocket (and if I wanted the look of the Tricorder man-purse I could always bring one of my EEE's along).

ETA: Drat. The online schedule's been changed, now it says there's no showings before 4:10 PM today, even though they had 1PM showings of movies on Mondays. Turns out corporate decided to go back on school-year schedule again until the end of the month, despite today being the perfect day to get college business (last day of regular classes).

Couldn't resist the pun. Sonic/Sonic Defender set to the minimum possible height and build.

Super-Kindle to be tested at CWRU, aimed at replacing textbooks. We may actually get to the "eTexts outnumber hardcopy" goal by 2012 like that one textbook publisher predicted a few years ago at an AAPT meeting.

ETA: Thanks to embracing the inherent corruption of AE farming, I got him to L24 in a couple of hours. :) And then I did the cape mission and got a little closer to the kind of cape I want:

dvandom.dreamwidth.org exists and is in the process of importing entries. It obligingly imported my friends list, but since I can't actually see anything by them until they set me to "allowed" it's not that much of a time-saver. So, this joins my Wordpress and Blogspot accounts as "grabbing the ID just in case, but not actually using it" list for now.

Way back in high school, in 1987 or 1988, I was introduced to the equation for angular magnification (as by a magnifying glass), that being m_θ = 25cm/f (where 25cm is the standard "near point" and f is the focal length of the lens). The explanation was kinda handwaved, and I didn't really get it, but I didn't need to get it in order to use the equation.

Yesterday, I finally ran into a homework question that required understanding the derivation, and I had to figure it out during class (the textbook being almost no help at all) so I could explain it to my students, oops. Turns out there's two very important assumptions that tend to get hidden or glossed over: you don't leave the object in the same place (i.e. you look at it as close as you can without the lens, then put the lens in place and MOVE THE OBJECT until you get a clear image), and the lens has to be right up in your eye so that the angular size of the object and the image are the same. Even our multiple-teaching-award-winning distinguished professor who's helping teach this class got tripped up on the second assumption.
