Hey, im making a super program that would do many chem conversions including heat problems, light problems, mole conversions, stoichiometry, isotopes, emperical formulas, and solutions. It also contains programs useful in geometry, such as Areas and volumes of many shapes, as well as side lengths of triangles. Some Algebra II segments are included such as slopes and quadratic equations/slopes. All of this is contained in ONE SINGLE PROGRAM! It is nearing 5k at the moment, but i could probably reduce the size significantly. If anyone has any suggestions, comments, or encouragement, please email me. PLEASE email me...

To decrease the size you may wish to focus your program on one area, such as chamistry. If the end user wants a geometry program let them get one. But do all people want a program that can do algebra and geometry when they are using their calc for chemistry?

I'm working on a program that will have many useful formulas for physics. To cut down on space it will not have much of a GUI and it won't be for beginners who may not understand physics. This is for college students who already know their formulas but want something to solve their formulas for them because some do take quite a while to calculate manually. Even by typing it into the calculator by hand. I will also probably port it to serveral different platforms like the 86 and 89.

I'm also working on a similar Geometry program. please tell me what you think because I'm uncertain wether I should put it on ticalc. Once again please reply.

I am working on a text based(don't laugh) Periodic Table. The status right now is it has elements 1-109 in alphabetical order, with name, symbol, atomic mass, ionization energy(where applicable) and valence electrons. If anyone out there knows of one with all of this or wants source code, just post requests here(my e-mail is malfunctioning).

Also on this are all ions formed by stable elements.

<replies to self> The ions are being replaced with the oxidation state number for each element- i.e. 3,2,4,7 where 3 is the most common.
I finished it the other day without ionization energies(no useful tables) and it ran to 10869 bytes, not bad for all it has!

Yo man you must have read my mind. I started making one and I would definitly like yours. Email it to me: gromero@eclipse.net


Thanks

does anyone know how to do this???
i tried zoemthing with matrices but i cannot figure out a way to store information in the way that the program can calculate it.

if ayone made this program, please send me the source code on my email address (milnikoletic@yahoo.com) because i don't have a cable yet.


thank you

If you want to do that, maybe you can use strings. I manage to do an equalizer using them, but it was very large. Basically, what I did was using Input to store the elements and their number, and storing them to strings. Then, I used the string functions in the catalog to allow the calc to process them,and at the end I made the program use this data and use the Algebraic balancing method. As you see, that way you can't have very large ecuations, and it doesn't solve all equations, but I'm working in a way to store all the info on just one or two strings. Tell me if you can do that.

I'm begginning to write a program that will balance chemical equations. so far i've figured that i will input equations like: Zn + KOH -> K2Zn2+H2 as (30) + (19)(8)(1) = (19)[2](30)(8)[2] + (1)[2]. I created the program to read both sides of the equation, calculate how many elements, and how many of those elements. Then i get stuck. If this idea helps anyone or if anyone has any idea on how to finish, email me.

I am writing a program to balance equations also. It has alot of tests and loops. about the ending, display all the elements and numbers but try using the graph buffer to display. (not enough room on the home screen)

Hi. I know it's been three years since you sent that message out but could you please e-mail me your periodic table program? I have been dying to get a periodic table into my calculator, but the programs never worked.

hi,
i just read that ur making a program for periodic table -- i am studying chemistry and physics, actually i dont a computer cable for my TI-83+ calcuter can u plz send the codes of the programs so that i can create it myself -- i will wait for ur reply -- thank you

IF anyone has the source code of any Periodic Table program pleae e mail it to me, ive problems with my link and cant download, thank you
email oz_os@hotmail.com

Hey Could I get the source code by any chance?

I am going to start making a SUPER CONVERTER! It will convert fahrenheit to celsius to kelvins and back again, inches to cm, cm to km, km to miles, miles to km, miles to cm and mm, pounds to ounces, tons to metric tons . . . well, you get the idea.
Please email me if you think I should continue this project or if you have any conversion suggestions. I'll probably eventually make it anyway for my physics class next [school] year so don't worry, you'll get your SUPER CONVERTER!

Dude i already have a program that does that and so much more. my APhysics program has a ton of formulas written in so that you can solve for almost any variable. however they are very large programs and might cause some ram probs

How about the science tools app from Texas Instruments? Very good.

Hello,
I am in the process of making a BASIC Periodic Table, right now I have about 5 rows done, it has the # of protons, neutrons, electrons, shells, name, and abr.
The program is very large and at the rate of bites I'm currently going it's going to be well over the limit, but I'm still working on that.

How are you programming your periodic table? I made one that is well under the 24K limit for the 83+. Post a segment of code and maybe I can help you pare it down a bit.

separate it into multiple prgms
dont put ending quotes or parenthesis IF THERE IS NOTHING AFTER IT

ex.
Disp "hi"
Disp "hi
-they both work but the latter is smaller and will make your prgm faster
but if your doing
Disp "Hi","Yall!
you must put quotes after the _Hi_
same goes for "For(","Output(", and pretty much any other command that ends in a "("

you can also use
GetKey
instaead of
GetKey->{some variable her}
it will be stored to "Ans" instead
