Harvard PHYSCI 10: Quantum and Statistical Foundations of Chemistry

Physical Sciences 10 introduces quantum mechanics and statistical mechanics as the foundations of chemistry — from single-electron behavior through the periodic table, chemical bonding, materials properties, and the thermodynamics of reactions. It can satisfy part of the pre-med general chemistry requirement.

What makes it hard

PS 10 is more mathematical than students expect from a chemistry requirement: calculus is used extensively, and the quantum material demands comfort with abstraction and probabilistic thinking. Students who chose it expecting a standard gen-chem course find the physics-flavored problem sets a genuine adjustment.

What you'll cover

• Quantum behavior of electrons
• Atomic structure and the periodic table
• Chemical bonding from quantum principles
• Statistical mechanics
• Thermodynamics of reactions
• Electronic and thermal properties of materials

The PHYSCI 10 study guide

How to study for Harvard PHYSCI 10, step by step.

1
Recalibrate your expectations in week one
PS 10 is a physics-flavored chemistry course, not gen-chem with extra steps. Accepting early that the problem sets will demand calculus and abstraction saves the mid-semester morale crash.
2
Keep your calculus tools warm
Derivatives, integrals, and probability-style reasoning appear throughout. A short weekly math review prevents the situation where the chemistry is clear but the math executes badly on exams.
3
Connect every formalism to chemical behavior
For each quantum or statistical result, write one sentence about what it explains — why the periodic table looks the way it does, why a bond forms. Exams test that connection, not the derivation alone.
4
Work psets in physics style: principles first
Identify the governing principle, set up the math, then compute. Students who hunt for a matching formula struggle; students who reason from principles find PS 10's problems systematic.
5
Pace the abstraction with Fennie
Upload the PS 10 syllabus and Fennie's Daily Plan distributes the math-heavy units into consistent problem practice paced to your exams, with quizzes linking formalism to chemical behavior generated from your actual materials. Free to start.

How Fennie helps with PHYSCI 10

Daily Plans pace PS 10's math-heavy units with consistent problem practice, keeping the calculus tools warm between psets. Chat through a quantum concept when the abstraction outruns intuition, and generate practice questions linking the formalism to chemical behavior — the connection exams test.

FAQ

Is PS 10 hard at Harvard?

It's one of the more mathematically demanding routes through the chemistry requirements — calculus throughout and genuinely quantum content. Students comfortable with physics-style problem solving fare best.

Does PS 10 count for pre-med requirements?

Harvard's pre-med guidance allows the general chemistry requirement to be satisfied by combinations of courses including PS 10. Confirm current combinations with pre-med advising.

Should I take PS 10 or PS 11?

They can be taken in either order; PS 10 leans quantum and statistical foundations while PS 11 takes a different angle on chemical principles. Pick based on your math comfort and concentration plans.

More Harvard courses

CS50 — Introduction to Computer Science

CS50 is Harvard's famous intro to computer science, taught by David Malan — and through CS50x on edX, almost certainly the most-taken and most-searched college course in the world. It moves from C through data structures, memory, and algorithms to Python, SQL, and web development, ending with a final project.

CS 51 — Abstraction and Design in Computation

CS 51 is the standard course after CS50 for Harvard CS concentrators, teaching functional programming in OCaml alongside design principles — abstraction, modularity, and multiple programming paradigms. It's where students go from making code work to making it well-designed.

CS 124 — Data Structures and Algorithms

CS 124 is Harvard's algorithms course — divide and conquer, greedy algorithms, dynamic programming, graph algorithms, hashing, and NP-completeness — combining rigorous analysis with programming assignments. It's a core theory requirement for CS concentrators and a known interview-prep powerhouse.

MATH 55 — Studies in Algebra and Group Theory / Real and Complex Analysis

Math 55 (55A in fall, 55B in spring) is Harvard's legendary honors freshman math sequence, covering proof-based abstract algebra, group theory, and real and complex analysis at extraordinary speed and depth. It's widely described as the hardest undergraduate math class in the country.
