"Recommended to all scientists." -- Journal of Royal Naval Scientific Service"The publishers do us a service by issuing this reprint." -- The Institute of Physics

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.

Glad I Gave It a Try
Flavor Name: Orange, Size: 15 Ounce (Pack of 1), Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
I wasn't sure if this Metamucil fiber supplement would make much of a difference, but after taking it consistently, I'm really glad I decided to try it. The results weren't instant, but over time I noticed that I felt lighter, cleaner, and just generally better overall. The sugar-free formula is a nice bonus, and it's easy to make part of a daily routine. I've found that consistency is key, and once I started taking it regularly, I could definitely tell a difference. If you're on the fence about trying a fiber supplement, this one has worked very well for me. It's a simple addition to my day that has had a noticeable positive impact. I'll definitely keep using it.

It works.
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
It really does help 'keep you regular' & the name brand dissolves easier than the generic W@lm@rt brand. It doesn't MAKE you 'go', it just gives your gut a little something to work with, so to speak. Maybe TMI, but you also go alot cleaner, if you catch my drift. That's a nice bonus. ;0)

Great to curb food cravings
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
Saw this on a YouTube video for reducing appetite/curbing snack cravings and wow! I’m on day 2 and this will always be in my pantry. After 30 min of drinking this I feel sooo full. No appetite for 4 hours like I ate a huge meal. The flavor is also good. No cramps or gas and the fiber content isn’t crazy so I haven’t experienced any negative side effects either. If you’re trying to lose weight this may help. Haven’t thought about snacking all day. Give it a try
