(Thermo is fixed, thanks!... Optics appears, to me, to need similar fixes.)
I've tried to paste a screen shot in here, and it won't go...
I copied the URL of one of the images and got: http://www.forkosh.dreamhost.com/mathte ... %5Ctheta_2
so...it's probably the exactly same issue.
I wonder if I just have to wait for a day or two for your changes to replicate through all the cached pages on the assorted distributed servers?
I access via Roadrunner, from Ohio. My DSN servers are 188.8.131.52*, my gateway is 184.108.40.206, and my IP address is very similar.
Thank you for checking and asking questions.
(I did poke enough to figure out how to edit the page in Chrome... when I deleted the .dreamhost from a few empty boxes, the formulas popped in. However, as soon as I refreshed the screen, my changes disappeared and the empty boxes returned. )
