happy "large boulder the size of a small boulder" day to all who celebrate

tweet from the "san miguel sheriff" twitter account, showing a boulder on the side of the road. the text reads: "large boulder the size of a small boulder is completely blocking east-bound lane Highway 145 mm78 at Silverpick Rd. Please use caution and watch for emergency vehicle in the area".

So fun to see this out! Thanks to friends, family, and colleagues for the support (and hi mom) perception.jhu.edu/files/PDFs/2...

screenshot of the first page of a bio of chaz for an apa early career award

excerpt from the article: "Chaz was born and raised in Toronto, Canada, to parents Sherry and Jay. His younger brother Ross is an MD/PhD who worked on the front lines of New York City’s COVID-19 response and now studies and treats rare cancers. “Even though he is half the doctor that Ross is (just a PhD),” Sherry once posted on social media, “I still love Chaz just as much!”" (the quote from chaz's mom is highlighted)

someone made an ames room for our department’s holiday party cookie decorating contest and it’s a travesty that it didn’t win

knew european soccer was hard to follow, did not know it was also hard to parse

highlighted text from a wikipedia article: "Since the abolition of the UEFA Cup Winners' Cup, the UEFA Super Cup place previously reserved for the Cup Winners' Cup winner has been taken by the winner of the UEFA Cup"

we made it boys! (from the @chronicle.com)

screenshot of a 'daily briefing' from the chronicle of higher education, about zeke and elli accepting an award with chaz:

Perhaps the most frustrating challenge for working parents is when they have two important places to be at the same time. But every once in a while, it all works out.

That happened recently for Chaz Firestone, an associate professor of psychological and brain sciences at the Johns Hopkins University. Firestone was to accept a distinguished scientific award for an early-career contribution in the area of perception and motor performance from the American Psychological Association. The award ceremony, though, was “scheduled at peak bedtime,” as Firestone put it in a Bluesky post.

The saving grace: The ceremony was on Zoom. So Firestone was able to attend, alongside his pajama-clad children, 5-year-old Zeke and 2-year-old Elliott. If the photos are any indication, the kids didn’t mind the change of routine.

Congratulations (and thank you) to @talboger.bsky.social, who lectured in front of nearly 500 @jhu.edu undergraduates today on the psychology of music! They didn’t see it coming, and then they loved it :)

So enjoyed hearing @ruizhegoh.bsky.social share his work on the perception of silence on the latest episode of @vox.com’s “unexplainable” podcast! 🤫 #poopoo
