This book is plain text that’s missing formulas and illustrations throughout the text

This book is the epitome of current science.

It's a good book, and it has its flaws but hey, it's free.

Pictures and formulas don't display. Invest in a hard copy...it is a wonderful book.

If you can follow the text and have a good college calculus background you can follow along. The fact that the images that are the equations are not present make this book especially hard to read

Einstein makes his theory easily understood and accessible to the average reader, but this edition is chock full of spelling and punctuation errors, and formulae and illustrations are missing.

When will they fix this?

Interesting to read, but formulas are missing from text.

There are spelling and punctuation issues that need to be addressed

This would be a great book, except the the figures and equations don't display properly.
