It's Friday, I think

This means I have some time to digest this over the weekend:

• Temperatures in Chicago rose 25°C, from -18°C to 6°C, from Wednesday evening to yesterday evening. They're forecast to plummet tonight. Yay Chicago.
• The Chicago Tribune has a decent history of Captain George Streeter, who "discovered" what is now the Streeterville neighborhood.
• Astronomers have discovered a supernova that was 50 times brighter than our galaxy.
• The Atlantic said last night's Republican debate had "Trump's Finest Moment." Not the whole debate, mind you; just one line of it. And the AP's fact-checkers had plenty to write.

I might have a chance to read this weekend. Perhaps.
