Best Free and Open Source Software – Science

Scientific Software
Science really prospers and advances when individuals share the results of their experiments with others in the scientific community. There is a certain logic that scientific software should therefore be released in a freely distributable environment.
Scientific - Maths, biology, chemistry, physcis, electronics & engineering and more
Physics - The study of matter and energy applying laws that govern natural phenomena
Chemistry - The study of matter and the changes it undergoes
Biology - Concerned with the study of living things
Bioinformatics - The application of mathematics, computing and statistics to the analysis of biological information
Desktop Genome Browsers - Visualize and browse entire genomes with annotated data
Web Based Genome Browsers - Visualize and browse entire genomes with annotated data
Graphical User Interfaces for R - For statistical computing and graphics

Get Started with Data Science with two tutorials to explore data science using Python or R. Both tutorials tackle the same basic data science task: manipulate and then visualise a data set.

Introduction to Python for Data Science

Introduction to R and RStudio for Data Science

Big Data
Big Data is an all-inclusive term that refers to data sets so large and complex that they need to be processed by specially designed hardware and software tools.
Search Engines - Full-featured search engines through an application programming interface
Data Analysis Tools - Examine huge quantities of data to find patterns, correlations, and more
File Systems - Storage solution which is designed to scale out on multiple servers
Key Value Stores - Allow the application to store its data in a schema-less way
Native XML Databases - Store data and documents without requiring a database schema
Health
Electronic Medical Records - For medical practitioners
Medical Imaging - To view DICOM images
Medical Practice Management - Supervise and support the day-to-day operations of a medical practice
Food and Drink - Nutrition, diet and BEER!
Eye Care - Look after your eyes
