Then, I spent some time chopping my little transparent images out by phone-light. Hopefully, the students don't mind some weird ones!

I did manage to get the transparancies to work, but I had to alter the images a little since there is no white ink....

Fortunately, someone at the institute decided not to throw out old-school transparencies, and I'm Millennial enough to remember they exist... so I decided to street-fight the printer.

It's a good thing I checked my supplies because I'm really short on some of the stickers. I have an activity where we use stickers of the Orion Nebula created by @livwithoutlimit.bsky.social to show the importance of using different wavelength observations.

One of my favorite possessions is a population science book from 1893 that talks about Vulcan, but raises doubts that it's real.
There's also an entry about the aether (!!)

Oh damn, I missed a whole week! Well the comment is still true, but voting is closed

Maybe it's just that I'm looking for a silver lining, but I'm glad that about half say there's no difference
