Write commentsIn our system, we sometimes have to memorize the so called derivations. I love understanding them. But i have trouble memorizing them. And of course we can't deduce what will happen next in some derivation and derive it ourselves in exams...right ? So what are some methods to remember or 'memorize' (i hate the word itself) the derivations. I almost forget them in exams. What were the methods you used to memorize them. Thanks ^o^

Reply@Prateek,

ReplyYou should never need to memorise a derivation.

A derivation, by its very nature, is a logical progression from one line to the next, until you turn your original statement into the desired result.

Memorising every individual step is a huge waste of brain power - and hugely inefficient.

When asked to do a proof in an exam, idelally you should work out the proof from scratch (or at least 90% of the steps).

That is why they ask you about proofs! Physics is not about memorising facts and deviations - it is about learning processes, and how to solve problems. In the exam they don't just want you to be vomiting up information, they want you to actually be understanding what is going on - and very often, they will actually ask you a subtly different proof - close enough that the proofs are recognisable, but you actually need to be able to adapt our knowledge, rather than just regurgitating the original proof.

It's fair enough to learn certain things about the proof - for example I know that to proof the Compton Scattering formula, one should use conservation of 4-momentum, and resolve along each axis: but that's all I've memorised about that proof.

Physics isn't about memory - it's about learning how to solve problems you haven't seen before.

https://neeraj-khandal.blogspot.in/2015/05/hc-verma-concepts-of-physics-volume-1.html

but I recommend you to purchase such an awesome book.

But in pdf of concept of volume 2 contains only questions, not the whole chapter. so, please tell me how can I download the wholebook?

ReplyAtul, You are right. Volume 2 PDF has only questions. Theory is excluded.

Replyfull version of part 2 isn't available on internet in form of PDF, you have to purchase it only.
