Not everyone is a fan. Some argue that GRB Vol 2 is needlessly difficult—more about mathematical trickery than physical insight. A 2021 analysis in the European Journal of Physics criticized the series for including problems that require knowing “non-obvious substitutions” (e.g., using $\int \fracdxx = \ln x$ in relativistic rocket equations where a simpler energy argument would suffice).
Others counter that Olympiads are a game, and GRB Vol 2 teaches you how to win. As one IPhO gold medalist put it: “After GRB Vol 2, the actual IPhO problems felt like homework from a kind teacher.”
Yes, but only if it is a complete, searchable, color scan with solutions. Unfortunately, 99% of the "grb physics for competitions vol 2 pdf" results online are low-quality scans from 2012. Using them will waste your time. grb physics for competitions vol 2 pdf
The Strategic Advice: Buy a used physical copy of the 2020 or later edition from a local second-hand bookstore or online reseller. Spend the ₹300-500. Then, use a document scanner app (like Adobe Scan or Microsoft Lens) to digitize only the chapters you struggle with. Build your own PDF chapter by chapter. This is legal, practical, and gives you a clean, annotated digital copy.
If the PDF remains out of reach, do not despair. The intellectual core of GRB Vol 2 is replicated in these accessible resources: Not everyone is a fan
| Resource | Coverage | Difficulty | | :--- | :--- | :--- | | “200 Puzzling Physics Problems” (Gnädig) | Similar trick-based problems | Intermediate | | “Physics for Scientists and Engineers” (Serway) | Foundational concepts | Low | | “Problems in Relativity and Gravitation” (Lightman) | Matches GRB Vol 2’s relativity section | Advanced | | IOAA past papers (2016–2024) | Experimental design + astrophysics | High |
Use these in conjunction with any partial GRB notes you can lawfully obtain. Others counter that Olympiads are a game, and
While Volume 1 covered basic lenses, Vol 2 focuses on wavefront division and amplitude division:
