Foundation of all physics. Covers vector calculus, eigenvalues, complex analysis, Fourier transforms, and special functions — the mathematical tools used across every physics topic.

SHM, coupled oscillations, wave propagation, interference, diffraction, and polarisation — explained from first principles with PYQ-focused problem solving.

Lagrangian and Hamiltonian formalism, central force problems, rigid body dynamics, and canonical transformations — taught by Atul Gaurav, the expert in Classical Mechanics preparation.

Postulates, Lorentz transformations, time dilation, relativistic dynamics, and four-vectors — with conceptual clarity and direct PYQ application.

Boundary value problems, Maxwell’s equations, electromagnetic waves in conducting and dielectric media, Poynting theorem, and radiation — taught by Dr. Alok Shukla.

The highest-weight section across all physics exams — Atul Gaurav’s Quantum Mechanics lectures are designed to build the depth needed for CSIR NET Part C and TIFR’s symbolic questions.

Thermodynamic laws, partition functions, quantum statistics (MB/FD/BE), Bose-Einstein condensation, and phase transitions — taught by Dr. Alok Shukla with emphasis on calculation-heavy PYQs.

Semiconductor devices, operational amplifiers, digital logic, and experimental methods — with emphasis on the circuit analysis and error propagation problems that appear in CSIR NET and GATE.

Atomic spectra, coupling schemes, Zeeman and Stark effects, molecular spectroscopy, Raman effect, and laser physics — taught with Atul Gaurav’s signature clarity on selection rules and spectral patterns.

Crystal structure, band theory, semiconductors, magnetic properties, and superconductivity — with the depth required for GATE Physics where Solid State is a heavy-weight section.

Nuclear structure, decay processes, Q-value calculations, nuclear reactions, and the quark model — taught by Atul Gaurav with his Nuclear and Atomic Physics specialisation.
