I scored 20/21 on #emailwtf

After reading great things about the author and great reviews of the book, this weekend I started to read “True and False Magic” by Phil Stutz.
I am completely puzzled as I read 47% of the book and I have absolutely no idea what I read. I am honestly feeling like the book and my brain are not overlapping even a bit.

Psi-Turing Machines: Bounded Introspection for Complexity Barriers and Oracle Separations
We introduce Psi-Turing Machines (Psi-TM): classical Turing machines equipped with a constant-depth introspection interface $ ι$ and an explicit per-step information budget $ B(d,n)=c\,d\log_2 n $. With the interface frozen, we develop an information-theoretic lower-bound toolkit: Budget counting, $ Ψ$-Fooling, and $ Ψ$-Fano, with worked examples $ L_k $ and $ L_k^{\mathrm{phase}} $. We prove an oracle-relative separation $ P^Ψ \neq NP^Ψ $ and a strict depth hierarchy, reinforced by an Ant…

Former Centers for Disease Control and Prevention (CDC) immunizations chief
Dr. Demetre Daskalakis said Sunday that
he’s concerned with the direction the agency is going and worried about public health going forward.
Daskalakis, who served as director of the National Center for Immunization and Respiratory Diseases,
submitted his resignation from the CDC on Wednesday in protest following the Department of Health and Human Services (HHS) removing CDC Director Susan Mona…

A Scoping Review of Machine Learning Applications in Power System Protection and Disturbance Management
The integration of renewable and distributed energy resources reshapes modern power systems, challenging conventional protection schemes. This scoping review synthesizes recent literature on machine learning (ML) applications in power system protection and disturbance management, following the PRISMA for Scoping Reviews framework. Based on over 100 publications, three key objectives are addressed: (i) assessing the scope of ML research in protection tasks; (ii) evaluating ML performance across …

Direct Measurement of Electron Heating in Electron-Only Reconnection in a Laboratory Mini-Magnetosphere
We report on the experimental observation of electron heating in electron-only magnetic reconnection in laser-driven laboratory mini-magnetospheres on the Large Plasma Device (LAPD) at the University of California, Los Angeles. In this experiment, a fast-flowing plasma impacts a pulsed magnetic dipole embedded within LAPD's magnetized ambient plasma, creating an ion-scale magnetosphere and driving electron-only magnetic reconnection between the background and dipole field lines. The electron ve…
