Challenging math for a dormant intelligence
1 of 1 found this helpful I have wanted to understand the mathematics of Quantum Mechanics for years but never penetrated the barrier. So finally I discovered this clearly written text that feeds the subject to you with a gentle spoon. It remains challenging because my brain has not been asked to comprehend such symbolic notation for many years. The journey will not be easy and the destination not final, but muscle will be retoned and the aches rewarded by the reassurance that results. If you are similarly inclined, hunt for a reasonably priced copy and begin your trek.
