one of those images where you should take some time to zoom in and pan around and marvel that this is an alien world currently ~150M miles away
Super-duper image from NASA's Mars rover Curiosity looking back at the floor of Gale Crater after setting a mission milestone by reaching 1 km of elevation above the crater floor.

asked claude to plot homeboy's # of publications by year, dude went beast mode
There's a chaired, full professor at UChicago who has put out *200* papers in 2026 alone. And at least one has been submitted to a journal (so potentially many more).
They don't all cite each other though -- rookie mistake.

Really good talk by Oz very much worth your time. Some of his slides. I hadn't seen the "jagged frontier" figure which is useful and I might steal w/ credit.
On Wednesday I gave a 'farewell' talk to my physics career (@Fermilab)
I outline my decision to leave for AI safety and why its so urgent
Recording is on Youtube for those interested!

"Let's just take a closer look."
Famous last words.
NSF–DOE Rubin Observatory images reveal stars, nebulae, and a mindblowing number of distant galaxies hiding in the background.
So go ahead. Zoom in.

11 years ago this month, one of the most legendary Boston viral videos was born.
Mikey Bergin and Jay Foster spotted a massive sunfish while fishing in Boston Harbor and delivered the unforgettable line:
“IT’S A BABY F@#$% WHALE!”

The entire space age was literally born on April 5, at a dinner party hosted by James and Abigail Van Allen at their home in Silver Spring. The food was allegedly great and post-dinner conversation over brandy in the living room gave rise to the IGY, which led directly to Sputnik
Brilliant @DKThomp take on the Decline of the American Dinner Party host.

I view the future with a superposition of immense optimism and absolute dread. Everything is going to be okay, potentially awesome, and also we are absolutely cooked.

The quiet superpower of my pre-kid life was being able to do whatever the hell I wanted in the evenings/on weekends. I used to "chill work" until 3am sipping wine & crank out almost a whole paper. Now I need to pick up the kids by 5 and it takes 2 hours to put them to bed.
