Concepts of Modern PhysicsThis book highlights foundational issues in theoretical physics in an informal, open style of lecture. It expresses the flow of ideas in physics from the period of Galileo and Newton to the contemporary ideas of the quantum and relativity theories, astrophysics and cosmology as explanations for the laws of matter. Rather than presenting the ideas of physics as a fait accompli, the book leaves it up to the reader to decide which of these 20th century
This book highlights foundational issues in theoretical physics in an informal, open style of lecture. It expresses the flow of ideas in physics -- from the period of Galileo and Newton to the contemporary ideas of the quantum and relativity theories, astrophysics and cosmology -- as explanations for the laws of matter. Rather than presenting the ideas of physics as a fait accompli, the book leaves it up to the reader to decide which of these 20th-century ideas in science will carry over to the 21st century for our further comprehension of the laws of nature in all domains, from that of elementary particles to cosmology.It is the contention of the author that our future progress in physics comprehension will only take place when the foundational controversies between the quantum and relativity theories are recognized and discussion is given to their resolution. The book, therefore, presents an attitude not normally taken in other present-day books on subjects in contemporary theoretical physics and cosmology.Shipping Notes

Solid iPhone Holder
Style: Magnetic Mount
I’ve been searching for a phone holder that doesn’t take up one of the drink holders and actually works well. I had been eyeing a vent mounted holder but was hesitant until I found this one. It had good reviews and was designed to work with my Tacoma. I decided to try it and was pleasantly surprised. It was easy to assemble, fit perfectly, secured nicely, and held my phone in place even in bumpy conditions. The vent location puts it in a good alignment with my vision which is especially helpful when I’m using my navigation app. If you’ve been looking for a decent, reasonably priced, well-built iPhone holder, this is an excellent choice!

Great Net!!
Size: 59 inches
The cargo net itself works great and keeps everything secure in my truck bed. The sticker tabs didn’t hold up well, so I switched to using the screws provided. The screws do the job perfectly, but installing them just feels wrong lol. Should be drilling holes in a brand new truck.

Great trunk bed cargo net holds a ton in place
Size: 59 inches, Size: 59 inches
Just what I was looking for. Easy to install and very easy to reposition in your truck bed. Great purchase would recommend holds all my groceries and anything else I put in well constructed strong.
This is great cause your items won’t slide all over the truck bed when you’re driving, it holds a bunch of bags or boxes.
It’s so strong my husband put sandbags inside the compartments and still great. I do highly recommend this net organizer it will also work on the back of an SUV.

Truck bed storage
Size: 59 inches
Great net, perfect storage space. Sticky mounts are useless! Be prepared to buy some heavy duty double sided outside tape to keep them in place but outside of that 0 complaints,

Best Bang for your Buck
Size: 59 inches, Size: 59 inches
Bought this almost a year ago for my 2018 silveraldo 1500 and it's very handy for big groceries shopping like Costco. I have a mat at the bottom just in case there's some kind of liquid and I dont want my groceries touching it.
Easy install, store a good amount of stuff, and pretty sturdy
