What can you say.
It is the book written by the scientific giant.
It is hard going in places because of the way that he wrote at the time.
Worth reading carefully. Many of the stories about Newton's discoveries in Optiks are not as usually stated. For example, it was well known that white light passing through a prism would create spectrum, he explained it, having purchased a selection of prisms from the market.
Everyone know that there are seven colours in the spectrum - except that anyone creating one using a prism will see that there are not. Newton did not get it wrong - we have got sloppy - Violet for example is not a specrral colour.
It is astonsihing to compare what Newton actually did (real genius) and decribed with what we have misrepresented.
Buy it and get Newton's own words...
