    WP 34s

    WP 34s

    Scientific/engineering firmware repurposing HP business calculators!

    This project has created scientific firmware for the HP-20b and HP-30b business calculators. WP 34S turns either of these calculators into a powerful keystroke programmable scientific device. According to our customers, it's the most powerful and fastest RPN scientific pocket calculator ever built. WP 34S is alive and stable since 2011. We have succeeded in satisfying the most picky users - read about their experiences on http://www.hpmuseum.org/forum/forum-8.html. Since 2014, WP 34S runs in version 3.3. Our customers confirm its documentation is excellent and comprehensive (see feedback); a full-color printed edition is available from https://www.amazon.com/dp/153366238X since 2018-10-15. Alternatively, you can get a personalized pdf-manual for a ≥ 9 US$ donation here. We have also produced the WP 31S which is derived from the WP 34S source code. This is an entry-level scientific calculator. Its printed manual is available from https://www.amazon.com/dp/1499231164 .

    RPNCalc

    RPNCalc

    RPNCalc - The command line Reverse Polish Notation (RPN) Calculator

    RPNCalc is the command-line based Reverse Polish Notation (RPN) calculator. RPN calculators make it very simple to do complex calculations, especially if there are parentheses involved. I've created a User Guide (https://frossm.github.io/RPNCalc-UserGuide) to do a better job of explaining how to use RPNCalc than the old readme.md file, which was getting really long. If you have questions, issues, feedback, or ideas, please let me know. You can contact me via the links in the **Introduction** page of the User Guide. ## RPNCalc User Guide: https://frossm.github.io/RPNCalc-UserGuide ##

    Alpha Dose Rate Calculator (ADRC)

    Alpha Dose Rate Calculator (ADRC)

    Alpha radiation code for dosimetry calculations by Angus Siberry

    ADRC is a geometrical alpha radiation code designed to calculate doses from radionuclide-containing solids exposed by surrounding media. The current version is only applicable to UO2 in water (radiolysis rates are also calculated in the results). More radionuclide containing materials and surrounding media options coming soon. **Note: All previous versions before v2 have an outdated script and any results used from simulations should be updated, reasons for this are explained in the technical release notes** UPDATE: This project has been migrated and developed to a cloud-based web application (http://rad-dose.herokuapp.com/)

    An easy and simple tool to calculate the half-lives of radioactive substances and looking up elements on the table of elements by name, element symbol, atomic number, or atomic weight. Source code is on GitHub here: https://github.com/InfinityDevelopment/ChemistryCalculator NOTE: This is a Java program. Inside the ZIP there is the .jar file and .bat file(which you would run to start the program on Windows) required to run on Windows, however, to run it on other operating systems you will most likely need to execute "java -jar program.jar" on it from that OS's terminal.

    Differential Calculator

    Differential Calculator

    Terminal calculator with differential error estimates

    This is a terminal calculator with a remarkable twist. It uses symbolic differentiation to provide a numerically precise error estimate with each calculated answer. It mimics the functionality of an HewlettPackard ReversePolishNotation [RPN] calculator simply because I like RPN. But along with your answer, you get some measure of its trustworthiness. Runs on PCs or laptops running Windows or Linux.

    EasyCalc Scientific Calculator

    A GUI Java scientific calculator

    EasyCalc is a Graphical User Interface (GUI) scientific calculator written in Java. It has a multi-line display and can evaluate many scientific expressions containing logarithmic, exponential, and/or trigonometric functions. It sports a nice and clean interface similar to that of the Windows 7 calculator (source of inspiration). I do not recommend its usage for ANY mathematical operation as it has some flaws left unfixed. It is presented here for academic purposes only.
