A brief discussion of the context of this object-oriented scientific computing library.

*There is little point in having a student to rewrite old code over again when there are so many great new problems that need solving.*-
*I wanted something easy to install and use.*

O_{2}scl takes advantage of homebrew
and travis-ci.org to make sure installation
and testing works.

*For example, lambda functions make mathematical methods much easier to implement.*

Function objects can now be defined and manipulated very succinctly:

double a=-0.9, b=0.9; o2scl::root_brent_gsl<> solver; std::function<double(double)> f=[](double x){ return sin(x)-0.1; }; solver.solve(a,b,f); cout << a << endl;(adapted from O

Python has enabled fast development, but we still want fast execution from C++. GSL is great for many problems, but Fourier transforms are better done in FFTW and linear algebra is better implemented in uBlas, Eigen, or Armadillo.
