Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the discipline?A branch of physical chemistry
2. What is the core methodology?Application of quantum mechanics to chemical systems, often through computational methods
3. How does quantum chemistry help make new medicines?Scientists use quantum chemistry to model how drug molecules might fit into a target in the body. This speeds up finding good medicines and reduces the need for many lab tests.
4. Why can't we solve the Schrödinger equation for big molecules?The Schrödinger equation is very hard to solve when there are many atoms, so it becomes too slow for computers. Scientists use approximations to make the calculations possible.

Quantum Mechanics: The fundamental theory in physics describing nature at the smallest scales of energy and matter.
Wave Function: A mathematical description of the quantum state of a particle, representing probability amplitudes.
Born-Oppenheimer Approximation: A simplification assuming electrons move much faster than nuclei, allowing their motions to be treated separately.
Density Functional Theory (DFT): A computational quantum mechanical modeling method used in physics and chemistry.
