A comprehensive survey of eighteenth-century knowledge about all aspects of light, Opticks also offers countless scientific insights by its distinguished author. One of the most readable of all the great classics of physical science, this volume will impress readers with its surprisingly modern perspectives.
In language that lay readers can easily follow, Sir Isaac Newton describes his famous experiments with spectroscopy and colors, lenses, and the reflection and diffraction of light. Book I contains his fundamental experiments with the spectrum, Book II deals with the ring phenomena, and Book III covers diffraction. The work concludes with "Queries" -- speculations concerning light and gravitation. Opticks is introduced with a Foreword by Albert Einstein.

Is super soft and works for elderly
Size: 2' x 3' (Natural shape, Sheepksin, Oblong), Color: Ivory White
My mom has been ill and confined to her recliner for sleeping. She developed pressure sores and was in a great deal of pain. We needed to treat the sores and I researched how to prevent in first place and found that genuine sheepskin helps. I had no idea this was a thing. I ordered this for her recliner and a seat one for the car. She loves this. She said she could feel an immediate difference in sitting for so long that she didn't need to shift constantly. I don't understand the mechanics behind why this works but I'm grateful for something natural and affordable like this to offer such relief.

Photo of the color differences for you!

The white one seems softer than the cream one!? Seems like great value for your money for a single pelt, the seller and product didn’t seem sketchy at all.

Great product: thick and cozy
Size: Single Pelt/2 ft x 3 ft, Color: Natural (Ivory Whiite)
This is a lovely, thick sheepskin. I’m using it to drape over a chair. It’s very soft. The color is a natural white. Arrived quickly. The price was great for such a wonderful sheepskin.
