I mean, every action this administration takes suggests that this is not spinelessness, as with past administrations. Most likely is that they actually agree.

lol I guess we haven’t earned our paper towels

Definitely not apropos of Sark’s salary but on most days we don’t have paper towels in our @utaustin.bsky.social restrooms. Would be willing to not call end arounds on 4th and 2 at the end of halves leading to 7-14pt swings in return for either $10M or a roll of paper towels…

Sometimes they destroy an entire curriculum just to force students to take classes in the sinecure centers. Hook ‘em!

France knew beating England 5-0 in a meaningless match would be, well, meaningless. But spotting England four goals and then winning 5-4? That might end England as a country.

Like when you hire a president who has no teaching or research experience (ever) and a provost whose only “academic” qualification is a hagiography of Reagan, stuff falls apart fast. I do my research under a tarp so that UT can save up money to offer Alex Jones a tenured position…

The @utaustin.bsky.social IT is so amazingly bad that we cannot access the *Army* Research Office website from campus. We have to submit our program reports from home. The thing you learn about authoritarian regimes (at macro or micro scales) is that they actually can’t make the trains run on time

Was early to pick up wife and daughter at the airport, so hopped on to an @austinenergy.bsky.social fast charger in the cell phone lot, and put 100 miles on the car in 10-15 minutes for less than $3.75. Just crazy how much better EVs are in every sense…

There’s been a lot of talk in this race about what makes a "real man." A man does what’s right when no one is watching. He upholds his commitments to his family and neighbors. He doesn’t lie, cheat, & steal his way through life. Real men serve others. Weak men serve themselves.

At my institution the only thing our administration likes more than pushing AI hiring slots on us is affirmative action hires for conservatives. You’re lucky you are at…checks notes…uh…. My institution?

Any self-respecting institution of higher learning would balk at inviting, much less celebrating, one of the most corrupt justices in memory, and a credibly accused sexual harasser. But not mine!!

It’s been “0” days since my university has publicly embarrassed itself. I wonder if he’ll talk about the part of the declaration that demands one take undisclosed bribes from oligarchs to coincidentally rule in their favor??

I think the quarterback for my university’s football team makes enough per year to fund my lab for ten years. Have you considered becoming the starting QB at UWisc? It has the added advantage that you’ll be doing something that the university actually cares about!

Miguel Centena taught a “western way of war” class that I TA’ed for in the early 2000’s. Enrollment was quite high, though it was sociology not history. Dunno if that’s still offered.

Every time I read about some horrible policy being implemented in higher Ed I am outraged and then realize that we’ve been forced to do that at UT Austin like forever.

I dunno what you are talking about everything works great the first time and no equipment goes down and I don’t spend so much time writing reports that I don’t have time to do science. It’s easy.

This is actually impressive. You should be proud, as a father, that your kids place the plates in planes including the z axis! My kids have been known to place dishes in the xy plane…literally resting in the tines. In fairness, they may be trying to induce a stroke in me

And to be clear, despite our decrepit infrastructure and obscene lack of funding for TAs we still are lucky compared to other departments at UT. The depts. that don’t teach anything ‘useful’, just writing, reading, and critical thinking, are in worse shape…325K a year could go a long way there…

Amazing. My students do extensive repeated cleans on samples b/c the building’s HVAC system spits black dust all over the labs. Experiments are done under a tarp b/c the roof leaks. But @utaustin.bsky.social will spend >300K on a speechwriter b/c we have a pres. who knows nothing about higher ed

That’s weird. I was given to understand that university leaders are only able to cower in fear and preemptively overcomply with the very worst interpretation of a legislature’s anticipated actions. Hook ‘em 🤘🤘🤘

It’s the phones. A world of distraction at their (our) fingertips as addictive as a drug. I can’t do anything about my students but the fight with my more distract-able child is non-stop, and absolutely soul-sucking. I wish I could smash that thing into a million pieces.

Exactly this. In fact, universities subsidize this vital research by paying 9 months of faculty salary and supporting the research infrastructure (which typically costs more than what comes in from federal grants!) Universities subsidize federal research, not vice versa!

we show that this metaplasmonic approach enables us to confine light down to a fraction of a free-space wavelength (ostensibly down to wavelength/100 or smaller). Write-up from @cockrellschool.bsky.social : cockrell.utexas.edu/news/archive...

Not a great sign when a basketball coach can offer a more spirited defense of academic freedom than @utaustin.bsky.social which has gone radio silent …and yes I know Steve Kerr is not just any bball coach…he’s actually, on paper, more qualified to be President of UT than Jim Davis, current pres.

In fairness, our president is a lawyer from Ken Paxton’s office who has never taught a class, never written a grant, never advised a student, and is only here to serve Gov. Abbott. It would be so amazing to have a president that believed in what we do. I’d even settle for a provost with a spine!

It’s great to see a school actually do the right thing, but there is a part of me that is so ashamed of the response of my institution @utaustin.bsky.social in comparison. Our administration can’t even muster an anodyne statement of support for the mission of higher ed.
