Finally, a concise, interesting, and clearly written book which explains electricity to readers who don’t have a technical background. All examples and situations discussed are related to the home. This book is intended for all persons, from curious young teens to adults who want to have a better understanding of this important power source. Irwin Math's book will give the ordinary person without a technical background a general idea of what electricity is, how it is produced, how we use and measure it, as well as the dangers involved with its misuse. A previous technical understanding of electricity is absolutely not necessary, and the book does not contain any complicated mathematics. Only one simple easy-to-understand formula is provided -- no more!!  The information given will also allow the lay person to begin to understand and even troubleshoot faulty devices, make simple repairs (often saving money in the process) and approach electricity with the respect it deserves. By carefully reading the chapters one will not only attain a good basic knowledge of electricity but be able to talk to an electrician, when necessary, knowing and understanding pretty much what he or she is explaining.

Comfort and Appearance
Size: 9, Color: Black
The shoes were as advertised. Marc Joseph (I hav 4 other pairs) are the perfect shoes for me with my physical needs. Additionally they are exceptionally comfortable and attractive. This pair I returned because they weren’t quite the right fit for me. They are, like my other Marc Joseph shoes, very well made and very attractive.

Ok in a pinch. Can get better shoes for the price. Wide aren’t wide
Size: 9 Wide, Color: Black/Black
These were ok comfortable. Would have preferred at the price point to be a little more comfortable. For being a wide size, the shoe was rather tight on my feet. Quality is ok. It passed for the wedding. Would probably have taken more time to pick something different if I had the ability to. This was a last minute purchase.
