`Even Janet Napolitano, who was the university president in 2020 and recommended a test-blind policy then, now favors its reversal. “It was a worthwhile experiment,” she told us, “but as the results come in, it is increasingly clear that the experiment needs to be revisited.”’

“The SAT, imperfect as it is, measures knowledge of the absolute basics and the ability to reason clearly under a time constraint. An SAT score would have told us—and Diego himself—the truth about his preparation before it was too late.“

Bring Back the SAT
California universities dropped the SAT to help low-income and minority students. The policy is doing the opposite, writes Svetlana Jitomirskaya, a professor of mathematics at UC Berkeley.

In a universe with many matter fields, the geometry does not fluctuate. Then we know what we mean by the Generalized Second Law of Thermodynamics, and we know what we mean by a Bounce (or cyclic) Cosmology. My recent theorem says you can't have both.

What's happening with these grants is much more complicated and mostly unknown. None of the NIH have been officially cancelled. The NIH was just ordered to stop paying. They got the Unis to enforce silence on their own campuses because they thought they were "negotiating" and cld get the funds back.

In addition to the terminations of existing awards, new NSF grants are still stopped completely since DOGE was granted access to systems a week ago. Last Thursday, an agency spokesperson said "NSF continues to issue awards." That does not appear to be the case.
