REAL-ID And US Airports

"REAL-ID FAQ: What will happen at US airports on May 7, 2025?" 

Author Edward Hasbrouck summarizes: "The key thing to know is that -- unless the TSA makes undisclosed changes to its procedures -- air travelers with 'noncompliant' ID on or after May 7, 2025, should be treated, and should be allowed to fly, the same way people with no ID fly today."

More On FFT

A nice ode to a bit of progress that has led to much of modern technology!


Do AIs Have "Rights"?

People now arguing whether AI should have "rights".  Seems that you first need a robust theory of what gives rise to the concept of "rights" and which entities this concept applies to.

Douthat On AI

Ross Douthat: "An Age of Extinction Is Coming. Here's How to Survive."

I think he's too pessimistic. But his essay does make some good points.

Human Vs. AI Reading Medical Notes

This question was posed recently on social media -- basically, asking someone to interpret a near-indecipherable orthopedic clinic note.  

My own translation:

Ortho
===========
R(ight) knee pain
R(ight) knee: + effusion, +pain, decreased ROM (range of motion)
Xray right knee: moderate OA (osteoarthritis)
A/P (assessment/plan): Right knee osteoarthritis
Right knee injection
F/u (followup) 3 months.

I also asked Grok AI to attempt to translate the image, and I have to confess it did surprisingly well!


 

 

 


Wave Confinement

"Thought To Be Impossible: Scientists Break Century-Old Physics Barrier". (Via H.R.)

A research team from POSTECH (Pohang University of Science and Technology) and Jeonbuk National University has achieved a groundbreaking feat: the complete confinement of mechanical waves within a single resonator—something long considered theoretically impossible. Their study, published on April 3 in Physical Review Letters, represents a significant advance in solving the century-old puzzle of bound states in the continuum (BIC).
