#### Quantum Chemistry Frequently Asked Questions

**What is quantum chemistry?** Quantum chemistry is quantum mechanics applied to chemistry.

**What is quantum mechanics?** Quantum mechanics is a physical theory used to describe the behavior and properties of microscopic particles like electrons, protons and neutrons in atoms and molecules.

**How do you apply quantum mechanics to chemistry?** There are several versions of Quantum Mechanics. The most basic theory, non-relativistic Quantum Mechanics is based on six postulates and one basic equation that describes the state of a systems: the Schrödinger equation. Applying Quantum Mechanics to chemistry means to solve the Schrödinger to study atoms and molecules.

**Is quantum mechanics reliable?** Quantum mechanics has so far never found to conflict with any experiment. There are problems when Quantum Mechanics is applied to black holes and the like, but as chemists: who cares about black holes?

**What’s the goal of Quantum Chemistry?** I am not sure how to explain this in two lines. My goal as a Quantum Chemist is to develop new methods to solve the Schrödinger equation. I am aiming at general methods that we will be able to apply to all types of molecules with the desired level of accuracy.
