Electrostatics: Exploring, Controlling and Using Static Electricity/Includes the Dirod Manual (Paperback)

The book was quite readable in back then, and should still prove such. One caveat: I have noticed some typesetting problems setting out equations -- fortunately this book isn't meant to be mathematically rigorous. Rather, it shows a number of simple experiments, variations in designs (besides the Dirods, there are the Shake-sphere and Pendulum machines, and Kelvin's water drop generator), and the basic theory (without heavy math) behind these type of generators.

The mid-60's photos and illustrations do pale in comparison to what could be produced today, using simple Word, Photoshop, and Illustrator (or even a 3-D rendering engine), but I find they are not a distraction.

I actually attempted to build the Dirod Jr, based just on memories of the book, during the mid-70's. Unfortunately, using hand-held jig saws, and drills (without even those cheap guide-rails that came out late in the decade) meant I had lots of misaligned rods. My biggest problem was in finding a suitable pickup-brush material.

My problems should not scare anyone else away from trying to build these machines.

Finally, let me mention that if one is considering between this book, and R.A. Ford's "Homemade Lightning"... BUY THIS ONE.

This book was one of my *all-time favorites*, one I checked out of the library until it was dog-eared and I was broke from fines and photocopy charges. I'm very glad to see it in print!

This book was fascinating and enlightening. It made electrostatics crystal clear to me. Perhaps its only fault is that it rambles like a novel without a textbook-like structure. But this is also part of its charm, and may be why it's so digestible.

_Electrostatics_ is as much a how-to book as anything. Designs for electrostatic generators and demos abound, including a section in the back with detailed instructions on building two or three of Moore's "dirod" static generators. ( I've never built one, but I'm dying to get started.. and I imagine they make ultimate science fair projects for the kiddies.)

I love this book. I'm getting a copy as soon as I pay Uncle Sam his due.

If you are aiming at a university degree, this book is not for you. Although the author of the book was a university professor, you will find no complicated theories, no frightening ciphers, but some formulas which can be computed with the simplest pocket calculators. The author wrote this book when his long university career had ended. He wanted to entertain young people and motivate them to enjoy experiments and possibly become engineers or scientists.

Moore was a famous experimenter and lecturer who travelled around the world with his apparatus, doing demonstrations. In the 1960s and 1970s, he wrote down his practical experiences in some kind of laboratory book which developed into the book I am talking about. Now you understand why the experiments and pictures in the book look a bit dated.

I like this book for its hands-on approach, but the book also has some aspects I dont like so much. Firstly, it is not a stringent textbook. It is a compilation of instructions on building machines and all kinds of obstacles you run into when trying to get them running. There are many drawings and some photographs in the book; the drawings often being very simple and the b/w images being not very clear. It is annoying that most of the formulas in the book were cut at the left and right sides so that many of them are unreadable or simply wrong because of a missing character at the edge.

American readers might appreciate that the author gives the dimensions of the mechanical parts in inches and feet. Even more annoying to me is the way he mixes up electrical units and dimensions in his formulas. For example, when calculating the energy of a charged capacitor, he gives us this formula: "oules= 1/2 C V", meaning the energy measured in Joules (the J was cut off) is half the product of capacity and voltage. Capacity is a dimension and volt is a unit. But this example also has its bright side. He tells us that (as a rule of thumb) 1/4 Joules is an energy that produces a very unpleasant (but harmless) electrical shock while 10 Joules is a fatal amount of energy.

The book has an index and a bibliography. The index is good but the bibliography is mostly useless nowadays because the referenced books were all published before 1970 and are out of print today. I still like the book, but others may prefer the book by R.A. Ford, Homemade Lightning, ISBN 0-07-137323-3.
