Nastase often provides comprehensive lecture notes through university repositories (like the arXiv or institutional websites) which serve as the skeleton for his published books.
Nastase avoids the "definition-theorem-proof" trap. He begins with the physical motivation: How do we reconcile quantum mechanics with special relativity? The book walks you through the historical development, from classical fields to second quantization, ensuring you understand why we need fields before learning how to quantize them.
