| mineralid.zip | 48k | 13-04-26 | | Mineral Identification
This document contains a program that uses attributes in a spreadsheet, such as streak and luster, to return a list of minerals that fit your constraints. Simply copy and paste the template and change fields to match your sample, or leave them blank. It can also return the chemical formula or properties of a mineral if you enter the mineral name. Only about 130 of the most common or economically important minerals are included. I'm an undergraduate geology student, so criticism and improvements are very welcome. |
| molecules_en.zip | 113k | 09-03-31 | | Molecules 3D
A 3D viewer of molecule structures. Includes several inorganic and organic molecules. Molecules can be rotated in space or animated. More info in www.nelsonsousa.pt |
| mom.zip | 3k | 10-10-21 | | Mechanics of Materials
Includes my previous Mohr's Circle program and a 3D stress program. The 3D stress will yield a the three stress invariants, the three principle stress, and the max shear stress for a defined state of stress. The user inputs the normal x, y, and z stresses followed by the xy, xz, and yz shears. (I'm hopping to include the direction cosines and the ability to do coordinate rotations in a future version. If people want those added, rate this program and leave a comment so I know that it would be useful to people.) |
| periodic.zip | 69k | 09-02-25 | | Periodic Table
Full Periodic Table on TI-Nspire with graphical interface. Data is presented in a spreadsheet. Includes plot of atomic properties and functions to determin an element's name, symbol and mass. |
| physicsunitsandconstantsm.zip | 167k | 12-11-02 | | Physics Formulas and Workspace
First, this package includes every formula that comes up in Calculus-Based Physics I and II. This allows you to copy and paste them into the solve() function, equivalent to 500 programs that might be written to manipulate equations on a TI-83. Second, this includes a pack of useful physics programs: converting units, storing variables with units attached even if you don't know them, and a quick-access menu for physics constants you can scroll through. This requires an Nspire version with CAS. In the latest update I've fixed some bugs, added a new program that can check your work between steps, and another that lets you store a list of values into a list of variables so you can plug a lot of things in really fast. Check the documentation in AAphysics! The main document you will be using is AAphysicsworkspace. The other three documents just house the code for programs so that the document where you'll be working will run faster. Your feedback is appreciated! |
