Description
Introduction to Special RelativityBy the year 1900, most of physics seemed to be encompassed in the two great theories of Newtonian mechanics and Maxwell's theory of electromagnetism. Unfortunately, there were inconsistencies between the two theories that seemed irreconcilable. Although many physicists struggled with the problem, it took the genius of Einstein to see that the inconsistencies were concerned not merely with mechanics and electromagnetism, but with our most elementary
By the year 1900, most of physics seemed to be encompassed in the two great theories of Newtonian mechanics and Maxwell's theory of electromagnetism. Unfortunately, there were inconsistencies between the two theories that seemed irreconcilable. Although many physicists struggled with the problem, it took the genius of Einstein to see that the inconsistencies were concerned not merely with mechanics and electromagnetism, but with our most elementary ideas of space and time. In the special theory of relativity, Einstein resolved these difficulties and profoundly altered our conception of the physical universe.Readers looking for a concise, well-written explanation of one of the most important theories in modern physics need search no further than this lucid undergraduate-level text. Replete with examples that make it especially suitable for self-study, the book assumes only a knowledge of algebra. Topics include classical relativity and the relativity postulate, time dilation, the twin paradox, momentum and energy, particles of zero mass, electric and magnetic fields and forces, and more.

Reliable and lasts forever Best budget option
Style: Combo, Color: Black, Size: 1 Pack, Style: Combo, Color: Black, Size: 1 Pack
I had this same model a long time ago and it lasted forever, I only had to get a new one because I lost the USB receiver, so I know for a fact they are very durable. For the price, you can't beat the compatibility you just plug it in and it works instantly. The appearance is very simple, it's not the most attractive or pretty keyboard since it has no lighting or fancy features, but it's built to last. The noise level is fine for a membrane keyboard, not too loud. In terms of ergonomics, it feels comfortable enough for daily work and the color is just the standard black that goes with everything. The best part is the battery life, it lasts months without needing a change.

Very comfortable to use
Style: Combo, Color: Rose, Size: 1 Pack
This is a nice keyboard/mouse for the money. I ordered it in pink because it will help me to keep it separate from others I have. I have a tendency to forget which mouse goes with which keyboard. The color makes all the difference. In addition this works well and has a light up indicator for the caps lock which my older one does not. That was annoying to look up and see that everything was in caps by mistake. Good product.

Works great, very happy with it!
Style: Combo, Color: Black, Size: 1 Pack
I really like this keyboard and mouse combo! It arrived in perfect condition and works exactly like it should. Setting it up was incredibly easy- you just plug in the little USB receiver and you are ready to go.
The keyboard is comfortable to type on, the mouse is smooth, and the wireless connection has been flawless. If you need a reliable, no-nonsense setup for daily use, this is a great choice. Highly recommend!
