In 1909 the great German physicist and Nobel Prize winner Max Planck (1858-1947) delivered a series of eight lectures at Columbia University giving a fascinating overview of the new state of physics, which he had played a crucial role in bringing about.The first, third, fifth, and sixth lectures present his account of the revolutionary developments occasioned when he first applied the quantum hypothesis to blackbody radiation. The reader is given a valuable opportunity to witness Planck's thought processes both on the level of philosophical principles as well as their application to physical processes on the microscopic and macroscopic scales.
In the second and fourth lectures Planck shows how the new ideas of statistical mechanics transformed the understanding of chemical physics. The seventh lecture discusses the principle of least action, while the final one gives an account of the theory of special relativity, of which Planck had been an early champion.
These lectures are especially important since they reflect Planck's reconsiderations and rethinking of his original discovery of quantum theory. A new Introduction by Peter Pesic places this book in historical perspective among Planck's works and those of his contemporaries. Now available in this inexpensive edition, it will be of particular interest to students of modern physics and of the philosophy and history of science.

Worth the price!
Color: Black, Size: 36"L x 5.5"W
Great product and easy to install. I purchased the 36 inch version and it’s just the right size for my desk. Makes securing and hiding the wires a breeze.

The best way to manage your cables.
Color: White, Size: 36"L x 5.5"W
Best cable management product I have used. period. I have used hanging baskets, tried 3m taping channels and tucking everything away. While that works. I change my setup fairly regularly. So hours spent to keep the cables perfectly managed just have to be redone when you add something or take something away.
I love the design. The canvas has velcro stitched into it so you can strap heavier items like power strips and bricks into the canvas and then just run your cables through the channel. When you close the canvas all the cables are out of sight leaving something that looks clean but is also versatile enough to support and evolving setup.
After everything I have tried, this has been the best hands down.

Exactly what I needed!
Color: Black, Size: 28"L x 5.5"W
This cable management tray is exactly what I need to complete my new desk. Being able to keep my cables organized and off the floor is essential, especially with a standing desk. The installation process was very simple. The clamps do not take up much space on top of the desk, I barely notice them. Overall, the tray is very sturdy with a thick fabric. It holds a fairly large power strip well along with my other cables. I also like that I can just unhook one side when I need to access a cable.

Works well
Size: 6.5 FT, Color: Black
This thing was a life saver. It has plenty of plug ports for the price and it's not huge. The footprint is a bit bigger than some others but it's not bulky. Seems well built and the fact that I can power all my electronics and still have the USB ports to charge my phone and things is nice.

Good quality surge protector.
Size: 6.5 FT, Color: Black
It's great to have a search protector that has this much versatility. One of the spots that this is mostly needed is around the TV area. With the need to plug in TVs, DVD players, surround sound theater system equipment, Xbox and PS5's, wifi router etc. This thing has more than enough plug spaces then you can throw it at a single time. The east of having all these connecting ports available in one compact place is a big win. It also eliminates running unnecessary wires being that old the plugs you need to plug in will have it available socket. This search protector also has a very premium feel due to quality materials.
Another great feature that it has is that you can hang it or drill it to a wall due in large part to its available pre drilled holes.
Also the way that the sockets are aligned are perfect to plug different types of plugs with enough space in between. There is enough separation to make different types of plugs fit snuggly.
