On this topic- any recommendations good books/articles on Maths/statistics, or how the mind does estimation, and how to improve the same? Back when I was in high school, I had read this book "How to develop a super power memory", by Harry Lorayne. I daresay, it was not a complete success for me :) But you could pull-off some pretty neat memory tricks, like remembering lists of items, phone numbers. The reason I quote this-the author's reasoning was that the "memory" of human mind works best when it is irrational. For instance,if you have a list of unconnected items like carpet,guitar,laptop- make an illogical association of one item to the next.For instance, in your mind's eye,"see" something ridiculous like you strumming a carpet, and so on. This actually did work for me, back then. So, has anyone tried out/read something similar for improving number estimation?
