Thanks! https://docs.einsteintoolkit.org/et-docs/meeting_agenda --The Maintainers From timothy.edgin at gmail.com Mon Jan 5 21:05:39 2026 From: timothy.edgin at gmail.com (Timothy Edgin) Date: Mon, 5 Jan 2026 21:05:39 -0600 Subject: [Users] [New Thorn] PrimeResonance - A Discrete Kernel for Manifold Resonance Message-ID: Dear Einstein Toolkit Community, I am writing to announce the release of *PrimeResonance*, a new Thorn developed to explore the intersection of number theory and field resonance within the Cactus framework. Project Overview: The PrimeResonance Thorn implements a discrete computational kernel that maps primorial moduli (P4, P5, P6, etc.) to continuous manifold rotations. This work bridges discrete number theory and continuous field physics, demonstrating that specific discrete phase mappings remain bounded and structurally consistent with the Fine Structure Constant ($\alpha^{-1}$) and the Golden Angle. *Repositories:* - Thorn Source Code: https://github.com/timtiminhous/Prime-Resonance-Thorn (Contains the CCL definitions and source implementation compatible with the Einstein Toolkit) - Mathematical Proofs (LEAN4): https://github.com/timtiminhous/ContinuityEngine (Contains the formal verification of the bridge theorem and kernel stability) License: This work is released under the PolyForm Noncommercial License 1.0. It is free for academic research, education, and non-commercial open source use. Commercial applications require a separate license. I welcome feedback from the community regarding the integration of this kernel into broader relativistic simulations.

Best wishes Helvi --------------------------------------------- Dr. Helvi Witek Associate Professor Department of Physics University of Illinois at Urbana-Champaign 247 Loomis Lab 1110 W Green St Urbana, IL 61801 --------------------------------------------- -------- Forwarded Message -------- Subject: DCOMP Early Career Office Hours Date: Fri, 09 Jan 2026 09:22:43 -0600 From: APS DCOMP To: hwitek at illinois.edu DCOMP Early Career Office Hours Dear DCOMP member, Recent years have seen a growing investment in computational research fields such as artificial intelligence, high performance computing, data science, biotech, physics simulators, and many others. This rapid expansion created a demand for specialized experts capable of maintaining and developing the complex computational software infrastructure. In response, the role of *Research Software Engineer *(RSE) has emerged as a distinct and increasingly important career path. A research software engineer combines strong software engineering skills with an understanding of research workflows. RSEs build, maintain, and optimize software that enables scientific discovery, data analysis, simulations, machine learning workflows, and other computational research tasks. They often work in academia, national labs, research institutes, or R&D teams in industry. Join us in our latest *DCOMP Office hours* , where we explore the career prospects and opportunities associated with the RSE career path. *What to Expect:* This event takes form in a one-hour virtual ?office hour? two speakers who are actively involved in the RSE community. They will share their experience in the field, discuss their current roles, and offer practical advice for navigating this career path. The sessions will also include open Q&A segments, giving attendees the opportunity to ask questions and gain candid insights on this specific career path. The coming session is scheduled for *January 21, 2026 at 11 a.m. ET*, and will host: Sandra Gesing Executive Director of US-RSE and Senior Researcher at San Diego Supercomputing Center, where her work focuses on computational workflows as well as distributed and parallel computing which inherently leads to highly interdisciplinary projects. Sandra is also Director of the Center of Excellence for Science Gateways, where she aims at supporting users, developers and providers of science gateways, with keen interest in sustainability of research software, usability of computational methods and reproducibility of research results while advocating for open science initiatives. Gabriele Bozzola Applied Scientist at the Amazon Center for Quantum Computing, where his work focus on the development of tools and techniques for the design and simulation of quantum chips aimed at quantum computing. Prior to joining Amazon, Gabriele was Senior Scientific Software Engineer for the CliMa project at Caltech, where he contributed to the development of robust and accurate open-source models for climate modeling in Julia. *Event details:* * Participants can register to the event here * The initiative is free and open to everyone.
