Any library for basic science chemistry/physics programming?

Question

I am wondering if there is an open source scientific library for chemistry and/or physics for C++ (or maybe C)?

I am NOT looking for simulation models, visualization, 3-d modeling.

I am just looking for a basic toolbox that would have, for example: various constants such as Ideal Gas Constant, Avogadro constant, periodic table of the elements values; molecular weight calculation; maybe basic functions implementing equations for stoichiometry, gas laws, thermal dynamics, kinetics.

Chemistry/Physics 101 kind of stuff.

I have found on SourceForge:

• Christoph Steinbeck's The Chemical Development Kit (Java) on SourceForge.
• NIST-const

Answer 1

I really like this book for it:

http://www.amazon.com/Physics-Game-Programmers-Grant-Palmer/dp/159059472X

I has the physics formulas in there and the source code is available online:

I haven't seen much in the way of chemistry. Physics is more popular because it has direct affect on gaming, of course. :-)

Update: a few on chemistry:

• http://www.iupac.org/inchi/
• http://code.google.com/p/simsoup/
• http://gchemutils.nongnu.org/
• http://www.simsoup.info/SimSoup/Design/Chemistry_Subsystem.html

Answer 2

I would take a look at the GNU Scientific Library:

http://www.gnu.org/software/gsl/

It should have most of the physical constants you're looking for. As far as the chemistry related stuff, I don't know of any basic packages that do all of those calculations right out of the box.

Update: I forgot about another project that would have all of the periodic table stuff (and probably more):

http://openbabel.org

specifically check out:

Answer 3

Since you excluded simulations, PyQuante probably isn't what you're looking for, but you might find kinpy and thermopy interesting.

Answer 4

Kalzium, part of the KDE tools. Periodic table plus (based on the screenshots) an equation solver and more.
