Who Are Gupta, Kumar & Sharma? Clarifying the Authorship
First, a clarification: While "Gupta, Kumar & Sharma" is a common author组合 in Indian academic publishing, the most famous quantum mechanics book under this name is often:
- "Quantum Mechanics" by S. P. Gupta, S. C. Sharma, and D. P. Khandelwal (not always Kumar)
- "Quantum Mechanics" by J. C. Upadhyaya (sometimes misattributed)
- "Quantum Mechanics: Theory and Applications" by A. K. Ghatak, S. Lokanathan (different authors)
The exact book you're looking for is likely: "Quantum Mechanics" by Gupta, Kumar, Sharma published by Pragati Prakashan, Meerut. Confirm the ISBN (e.g., 978-9350123456 — verify via publisher). The latest edition is usually the 5th or 6th edition (updated 2019–2023).
The "Free" Problem
The latest editions (5th, 6th, or 7th) of this book are copyrighted. While many websites (Library Genesis, PDF Drive, or student Telegram channels) offer scanned copies, these are unauthorized and often violate copyright law. Furthermore, these scanned PDFs are frequently:
- Missing pages (especially the crucial index or last chapters on perturbation theory).
- Low resolution (blurry equations make quantum mechanics impossible to study).
- Old editions (see below).
3. University & State Digital Libraries
Government initiatives like e-PG Pathshala (MHRD) and NPTEL do not host the GKS book directly, but they host the exact same content mapped to the GKS syllabus. You can download the notes that correspond chapter-by-chapter to the GKS textbook for free.
Pro Tip: If you are a registered student, check your college’s Institutional Access (like Shodhganga or INFLIBNET). Many have digital copies for internal circulation.
Ethical & Academic Best Practices
Using pirated books harms:
- Authors – They receive no royalty, discouraging them from producing future updated editions.
- Publishers – Small academic publishers like Pragati Prakashan struggle to survive against piracy.
- Your own learning – Pirated copies often have missing pages, garbled equations, or incorrect problem solutions.
Instead, write to the publisher – Many academic publishers offer hardship scholarships (free e-book access for students with demonstrated financial need). Send an email to Pragati Prakashan’s customer support with your college ID and request a complimentary digital copy for academic use – sometimes they oblige.
