Here’s a great TI emulator for your Android device.  You will have to download your own ROM, but it works great.

Andie GraphGet a TI-82, TI-83, TI-85, AND TI-86 emulator for your phone!ROM NOT INCLUDED. Due to a request from TI, this app will NOT WORK until you EXTRACT YOUR OWN ROM. See http://supware.net/roms for details. This is similar to other emulators on the market: GameBoid, SNESoid, GBAEmulator, NESoid, psx4droid, etc The TI-8X series of calculators work great as standalone calculators, showing 8 lines of history, using standard mathematical notation.

Microsoft Mathematics 4.0

Microsoft Mathematics 3D graph
3D graph

Microsoft Mathematics 4.0 is a free mathematics program from Microsoft (if you couldn’t already tell that from the name) for Windows.  It is definitely a better upgrade to the standard windows calculator, and keeps a notebook of calculations/graphs.  It is more geared toward students, but can be useful for a general graphing calculator for anyone.  It can also be used with a tablet computer and stylus to accept written input.

Microsoft Mathematics provides a graphing calculator that plots in 2D and 3D, step-by-step equation solving, and useful tools to help students with math and science studies.


Microsoft Mathematics provides a set of mathematical tools that help students get school work done quickly and easily. With Microsoft Mathematics, students can learn to solve equations step-by-step while gaining a better understanding of fundamental concepts in pre-algebra, algebra, trigonometry, physics, chemistry, and calculus. 

Microsoft Mathematics includes a full-featured graphing calculator that’s designed to work just like a handheld calculator. Additional math tools help you evaluate triangles, convert from one system of units to another, and solve systems of equations.

HP-48 Emulator for Android

For those of you who just loved your RPN HP48 graphing calculator and have an android phone, this app is for you.  Just looking at the screen brings back memories.  The developers have faithfully recreated the original calculator’s look and feel.  If you are a RPN fan, and you need a little more power than just a scientific calculator on your phone, then this is definitely worth a look.  From the developers:

HP 48 lives again on Android!

Emulator of the HP 48 scientific calculator, using RPN. Port of the X48 project (sources available on github). HP48’s “grayscale mode” cannot be emulated.

Visit www.hpcalc.org for a large program collection.

Cool tip: tap the HP’s LCD to show/hide a simpler numeric pad !

RealCalc Scientific Calculator

RealCalc Scientific Calculator for Android is made by Quartic Software.  This is a great standard scientific calculator which only shows one entry at a time.  There is also a setting for RPN functionality.  This is a great substitute if you want to leave your scientific calculator behind and need to do some light calculations using your Android phone.  This app is not very processor intensive.  Two screenshots from the developer’s website are below:

GraphCalc The Ultimate Windows 2D/3D Graphing Calculator Software

This week, The Engineering Zone will feature calculator applications.

One of my Favorite PC calculators is GraphCalc (also available for Linux).  It is fast, easy, and you can use your number pad for input.  Even though it was last updated in 2003, it still works great on newer computers with Win7.

GraphCalc is ready to use out of the box. Don’t bother reading the documentation. Just start the program and you’ll see how easy it is to use.

Have a look at some screen shots of GraphCalc

This software is free and open source, so you can use it everywhere.  You can even export the 3d plots to DXF files.  These files can be imported into other programs.  This is convenient for surfaces that can be defined by a mathematical equation.

Wolfram|Alpha – Intro

Wolfram|Alpha computational knowledge engine

Wolfram|Alpha is becoming a more valuable tool for engineers practically every day.  If you haven’t used it before, you should definitely check it out.  Their goals are summarized on their info page:

Goals

Wolfram|Alpha’s long-term goal is to make all systematic knowledge immediately computable and accessible to everyone.

We aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything. Our goal is to build on the achievements of science and other systematizations of knowledge to provide a single source that can be relied on by everyone for definitive answers to factual queries.

Wolfram|Alpha aims to bring expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels.

Our goal is to accept completely free-form input, and to serve as a knowledge engine that generates powerful results and presents them with maximum clarity.

Wolfram|Alpha is an ambitious, long-term intellectual endeavor that we intend will deliver increasing capabilities over the years and decades to come.

With a world-class team and participation from top outside experts in countless fields, our goal is to create something that will stand as a major milestone of 21st century intellectual achievement.

You can do a lot with it.  It can definitely serve as a quick replacement when you need to consult an infrequently-used table for some data.  What is the bulk density of sand?  Need to know the coefficient of thermal expansion for Copper?  What about the general properties of elemental Silicon?  Need to solve some engineering problems?  These examples only scratch the surface of the large number of topics that Wolfram|Alpha covers.

First Public Review of the 2011 AISC Nuclear Specification

from American Institute of Steel Construction:

The AISC 2011 Specification for Safety-Related Steel Structures for Nuclear Facilities AISC N690 is now available for public review. The entire draft specification is available for your review by downloading the attached document. This is an update of the 2006 version of this document ANSI/AISC N690-06. This version of the AISC Nuclear Specification uses the 2010 AISC Specification for Structural Steel Buildings as a baseline document and modifies specific portions of the Specification to make it applicable to the design, fabrication, and erection of safety-related steel structures for nuclear facilities.Comments are welcome on any portion of the draft in this first public review.

Their website also gives information for obtaining a hardcopy.

Custom Graph Paper

Green Engineer's PadMost of us professionals have pre-printed graph paper with the company logo and other things.  Students usually have to buy their graph paper in bulk from their bookstore, Amazon.com, or somewhere else (probably online).  When I was in school, we used a green engineering pad similar to this.

What happens when you’re in the middle of a homework assignment, and you just run out of graph paper only to realize you forgot to go to the bookstore before they closed, and your assignment is due tomorrow?  (If you are running low, you may want to order a pad or two now while you are thinking about it.)  What if you just need a few sheets to get you by, or if you need some grid pattern that you don’t usually use?  One option is to print some yourself.  It is quite easy–you don’t even have to draw it in AutoCAD or make it in Excel!  All you have to do is go to incompetech’s website and print any custom grid pattern, type, and size for free as an instantly downloadable PDF.

Blender 3D 2.57 Relased

image credit: Blender Foundation

Blender 2.57 has been released!  This is one of my favorite free open source 3d programs.  It is very robust, and is great for visualizations and concept art.  This is the first stable release of the 2.5 series.  The 2.5 series features a massive code rewrite and upgrades in every area including the GUI, physics, rendering, animation, modeling, and internal architecture:

The Blender Foundation and online developer community is proud to present Blender 2.57. This is the first stable release of the Blender 2.5 series, representing the culmination of many years of redesign and development work.

We name this version “Stable” not only because it’s mostly feature complete, but especially thanks to the 1000s of fixes and feature updates we did since the 2.5 beta versions were published.

The next 2 months we will keep working on finishing a couple of left-over 2.5 targets and we expect to get feedback and bug reports from users to handle as well. If all goes well, the 2.58 version then can be the final release of the 2.5 series, with a massive amount of new projects to be added for an exciting cycle of 2.6x versions. Target is to release updates every 2 months this year.
