Hi, my lecturer insists that I buy the brand-name textbooks from all of the branches of physics and to start a collection of these. He insists that using ebooks is not a good approach to learning. Now, he proceeds from the assumption that I will become an academic for whom these textbooks will be a lifelong asset. But, you never know what happens when to people. What are my chances of ending up being a physicist? Next to naught. This applies for everyone. You never know where life will take you. Why then bother spending tonnes of money on these books, if only you need to refer to only a chapter from his book and another chapter from that book?
