# Domains

Quantum This subcategory is for discussion around quantum physics and related packages. Geo This subcategory is for geo-related discussions. This includes using Julia in geosciences, or dealing with geospatial data. Machine Learning Machine Learning in Julia, with a particular focus on Deep Learning Probabilistic programming Julia at Scale Julia at Scale is all about running Julia on large parallel distributed computing systems, may it be the cloud or supercomputers. We welcome question and discussion around how to get started, best practices and challenges with running Julia at scale. Data This subcategory is for discussion around data management: importing/exporting data sets from files or databases, manipulating data, summarizing data, etc. Also welcomed is discussion about the projects or packages maintained by the organisations below. Astro/Space Discussion of Astronomy, Astrophysics, Astrodynamics, and other space related disciplines in Julia. Current Git organizations include: Optimization (Mathematical) For discussion of mathematical optimization software in Julia. This includes modeling software and solvers for linear optimization, mixed-integer optimization, convex optimization, nonlinear optimization, semidefinite optimization, and related topics. Biology, Health, and Medicine This subcategory is for discussion around biology, bioinformatics, computational biology, medicine, individual health, health care, public health, and biomedical research.
