Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Schrödinger's Doctrine of Identity: On the Role of Advaita Vedānta in Erwin Schrödinger's Thought

Berichte zur Wissenschaftsgeschichte, EarlyView.
Ever since Erwin Schrödinger learned about Indian thought through Arthur Schopenhauer, it occupied a visible role in both his published writings and personal books. Schrödinger called for a “blood transfusion” of Indian thought into the West and, in one notebook, construed the Upaniṣadic slogan “Brahman = Atman” as the “closest thing to the truth ...

Physics of Protein Aggregation in Normal and Accelerated Brain Aging

BioEssays, EarlyView.
Soluble monomeric proteins precipitate via nucleation into insoluble amyloids in response to age‐related exposures (e.g., microbes, nanoparticles). Persistent soluble‐to‐insoluble phase transition depletes the functional proteins. In normal aging, replacement matches loss; in accelerated aging, it does not.

Biology wet lab e‐learning during and after the COVID‐19 pandemic: A review of student learning and experiences

Biochemistry and Molecular Biology Education, EarlyView.
Abstract The COVID‐19 pandemic began as a health crisis and quickly turned into an economic, social, and political crisis. It revealed the vulnerability of education systems to external changes and risks and challenged institutions and educators to transform and adapt at short notice. Following the COVID‐19 outbreak, one of the natural consequences was
