Me: Where are my keys?!

Me: Oh yeah! They're in the zeolite!

Just got this for the group space, for when a large campaign of compute jobs needs to be rerun. 😅 Happens to the best of us...!

In the "Select Subset" view. I think it's the same one you're looking at here.

I've heard 6th is actually the new 1st. 😉

If anyone has any doubts, they should read the following excerpt below from an interview with Chris Rufo in the NY Times. It can hardly even be called a smokescreen. The plan is visible for the world to see.

I am getting severe Pepe Silvia meme vibes from some of the students' answers on my final exam. 😅 They typically get it in the end, but the journey is a bit of an emotional roller coaster.

I wasn't paid to say this, but I absolutely love the molecular/materials models I purchased from m.miramodus.com. I use the zeolite one all the time, and the buckyballs are fun fidget toys. 😅

I would really like to request an exam copy of The Gull Guide, but I feel like it would be difficult to justify for my graduate reactor design course. I'm sure I can figure something out though.

Spent the day discussing AI and materials science on the White House grounds. Super thought-provoking meeting! 😁

Alright, time to get started on this one... 😅 #RosenReview2

What are the odds I can get one of these fellas on my lawn when I move to Princeton? 😅

(That's one of the few things I'll miss about CA...)

My response when anyone sends me an email for some calculations while I'm vacationing in Hawaii.

A ~2 yr late honeymoon, but better late than never!

I uninstalled Slack from my phone. Muted all notifications. Peace at last! 😅😎
