Light enables us to see the world around us. Our sense of sight provides us with direct information about space and time, the physical arrangement of the world, and how it changes. This almost universal shared sensation of vision has led to a fascination with the nature and properties of light across the ages. But the light we see is just a small part of the whole spectrum of electromagnetic radiation, ranging from radio waves to gamma rays.In this Very Short Introduction Ian Walmsley discusses early attempts to explain light, and the development of apparently opposing particulate and wave theories by scientists such as Isaac Newton and Christiaan Huygens. He shows how light was recognized as an electromagnetic wave in the 19th century, and the development of the quantum mechanics view of wave-particle duality in the 20th century. He also describes the many applications of light, domestic and scientific, such as microwaves, DVDs, and lasers. We now use the whole range of electromagnetic radiation to peer both into the human body and deep into space. Turning to the future of optics, Walmsley concludes by looking at some of the most exciting new developments using quantum light sources in communications and computing.

The shelves sag away from the wall overtime
Color: White, Number Of Shelves: 2, Size: 15.7in, Color: White, Number Of Shelves: 2, Size: 15.7in
Although the wood quality and finish of the shelf are clean and well-made, the main issue is that the shelves begin to sag over time while holding around 10 pounds, even though the product listing claims they can support up to 20 pounds. They may perform better on a brick wall, but on drywall you should be cautious.
To fix the problem, I had to purchase floating shelf brackets for support, which solved the sagging issue. However, this defeats the purpose of the βfloatingβ aesthetic. Since the shelf is in my bedroom, I can overlook it, but I personally wouldnβt install these in a common area if I wanted a clean floating look.

Looks nice, easy to install
Color: Rustic Brown, Number Of Shelves: 2, Size: 22in
This shelf is lightweight, looks nice, and was easy to install. It comes with a little level to help you install it properly. There are plenty of mounting holes to choose from, so it is easy to screw it directly into a stud, or to just use holes that are convenient for you. It comes with a plethora of mounting hardware.
I mounted mine a bit high up and chose to mount it upside down so that I wouldn't see the three screws that hold the shelf to the mounting bracket.

Light weight and large privacy screen

The privacy screen is light weight and of great quality. The screen can block sight and also is easy to set up. It screen is sturdy and stable. It is a cheap solution for separating paces in rooms. The privacy screen is of black color and good good in many places. It can be folded when not used and does not take much space for storage.
