If anyone’s struggled to keep up with my threads on why the genAI bubble
Is a bubble, here’s a simplified pictorial explanation, the plug is OpenAI and the sockets are Microsoft, Meta, Oracle, Nvidia, and AMD

Gallup has been surveying Americans' trust in legacy media since 1972. This year, a mere 28 percent of the public have "a great deal" or "a fair amount" of trust in legacy media, its lowest level in more than five decades of tracking.

Picture the worst kid from your high school. The kid who had no self control, always trying to fight someone and constantly getting suspended. Now multiply that kid by every class year and every high school in America. That’s who they’re hiring to work for ICE.

Valuable info about the Physics Nobel Prize today from Prof. Joseph Barranco at SFSU on Martinis and Devoret being a grad student and postdoc in Clarke's lab at UC Berkeley & Clark and Devoret being immigrants. "California *public* education made this happen. Immigration made this happen." ⚛️

Joseph Barranco posted on social media: Go Bears! Nobel Prize in Physics goes to 3 physicists studying mesoscopic quantum phenomena... Work was done in the 1980s in UC Berkeley Professor John Clarke's lab with his graduate student John Martinis and postdoctoral fellow Michel Devoret... all 3 share the Nobel Prize. Must also point out that both Clarke and Devoret are immigrants from the UK and France, respectively. All 3 are pioneers in the race to build the most powerful quantum supercomputers. California *public* education made this happen. Immigration made this happen.

The work was actually done at Berkeley in the 1980s… but all the faculty do impressive research!

The Nobel Prize in Physics 2025 has been awarded to John Clarke, UC Berkeley; Michel H. Devoret, Yale and UC Santa Barbara; and John M. Martinis, UC Santa Barbara “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.” #physics 🎢

So apparently the woman shot in Chicago, Marimar Martinez, never rammed into an ICE vehicle or pointed gun at ICE.

Her lawyer says he has body cam footage of the attack. What really happened is that her and others were following ICE, then an ICE agent rammed into Martinez's car & shot her 7 times.😥

Body-camera video appears to contradict the government’s claim that Marimar Martinez, 30, drove toward officers before one of them opened fire at her late Saturday morning in Brighton Park, her attorney claimed.

Attorney for woman shot by Border Patrol claims officer said 'Do something b-----' before shooting

Body-camera video appears to contradict the government's claim that Marimar Martinez, 30, drove toward officers before one of them opened fire at her late Saturday morning in Brighton Park, her attorney claimed. A judge ordered Martinez and a co-defendant released pending trial.

Thanks, Ted! One approach that the cheese-paring administrators might go for is to state that the discussions will be used for active learning exercises, which are known to improve both student performance and student retention. S. Freeman et al (2014) doi: 10.1073/pnas.1319030111 1/2

I very much agree with their conclusion that “taking a high school physics course has a modestly positive relationship with the grade earned in introductory college physics.” I find the students who took such a course are at a slight advantage until about week 4 - but not after that.

Roger Freedman @rogerfreedman.bsky.social · 2d

Thanks, Marta! That may help explain why so many first-year college students have no idea how to use a STEM textbook. Through no fault of their HS teachers or of their own, they may never have had to.

Roger Freedman @rogerfreedman.bsky.social · 2d

Is it your sense that most HS physics teachers have decided to create all their curricular materials from scratch, as you so commendably have done, and that they do not recommend existing textbooks (even free ones) to those students who ask for additional references?

For these students, education seems to have reverted to the 14th century, with only the lecturer having a copy of the precious book…

And yet these students say that their teachers are not even suggesting any textbooks as secondary sources.

Thanks, Brian! Id love to hear from current AP teachers as well.

And there is indeed an OpenStax high school physics textbook: openstax.org/details/book...

Roger Freedman @rogerfreedman.bsky.social · 2d

The comments I see are from students taking AP physics, for which the OpenStax college physics book should be appropriate. That this is not even suggested to these students baffles me.

Hopefully the whole Bari Weiss thing and Ezra Klein thing starts waking people up to the fact that corporate media is mostly populated with mediocre people who have made millions and gained unbelievable influence because they threaten nothing and tell wealthy people exactly what they want to hear.

Thanks! I wasn’t sure whether your goal was to institute or retain them. What is your vision for the sections?
