Many of the critical issues facing our society involve chemistry. Alternative fuels, green energy, prescription drugs and their effects, high temperature superconductors, and recyclable materials are all active areas of chemical research. The physical laws which govern all of chemistry have been known for nearly a century but lead to mathematical equations that can only be solved approximately. Most approximate methods face a trade-off between accuracy and cost, and obtaining the correct result often requires extremely accurate calculations. Obtaining such high accuracy is excruciatingly time-consuming. We are developing a set of new approaches that will achieve sufficiently high accuracy with much less computational cost than existing methods.
