Outerzone is an archive that collects and shares plans of vintage and old-timer flying model airplanes for free. The site states it has 16,962 plans available for free download and does not require a login. It also notes it is currently dealing with a trademark dispute involving a similarly named site.
OEIS is the On-Line Encyclopedia of Integer Sequences, maintained by The OEIS Foundation Inc. The site is available in many languages. It offers lookup, an index, plots and transforms, and reports containing 400313 sequences.
A three-part curriculum aimed to help beginners self-study mathematics, covering core undergraduate subjects, electives, and possible study tracks. It assumes a modest background, mostly high school mathematics, and emphasizes solving exercises and problems.
Deployed Medicine is a research and development activity sponsored by the Defense Health Agency in partnership with the Joint Trauma System and Committee on Tactical Combat Casualty Care. Since 14 December 2023, users must be signed in to access its content.
A large online directory of thousands of free e-books on science and technology subjects, including computer science, medical science, mathematics, physics and biology. Users can upload their own books, which are checked before being added, or request a book. Links are listed by publisher and category with a download link for each title.
OpenFOAM is a free, open source computational fluid dynamics (CFD) software developed primarily by OpenCFD Ltd since 2004. It offers an extensive range of features for solving complex fluid flows involving chemical reactions, turbulence and heat transfer, as well as acoustics, solid mechanics and electromagnetics. Releases are scheduled every six months, and the software is distributed under the GPL v3 licence.
Wokwi is an IoT and embedded system simulator for ESP32, STM32, Arduino, Raspberry Pi Pico, displays, sensors, motors and WiFi, run online in the browser. It also offers options for VS Code, CI and JetBrains, plus a classroom offering used by universities and organizations.
