The first edition of The Sources of Invention, published in 1958, has been described as "a classic in science policy which has had a very considerable influence on both economists and scientists in Europe and in the United States." The authors set out to study the causes and consequences of industrial innovation--one, if not the main, spring of economic progress. They examined the important inventions of the nineteenth and twentieth centuries in order to discover just how far recent inventions have emerged from conditions different from those of the past. The evidence collected threw light on many questions, such as the influence of large research institutions and the concept of teamwork, the arguments for monopoly in industry, and the possibility of predicting inventions.

The second edition is a considerable enlargement of the first. To the original group of fifty-one case histories--which included Automatic Transmissions, Fluorescent Lighting, the Helicopter, Kodachrome, Polyethylene, Synthetic Detergents, the Transistor, and Xerography--have now been added ten other recent important cases, each of which has its own fascinating peculiarity: Air Cushion Vehicles; Chlordane, Aldrin, and Dieldrin; Electronic Digital Computers; Float Glass; the Moulton Bicycle; Oxygen Steelmaking; Photo-Typesetting; the Cure for Rhesus Haemolytic Disease; Semi-Synthetic Penicillins; and the Wankel Engine. A new chapter evaluates the relevant literature of the last ten years.

Durable
Omg my dog loves this. The rubber is so durable my 2 yo aussie hasnt torn it up yet. I bought a cheap one from temu before and it took only 2 mins for my dog to tear it up it was complete waste of money. I love the football shape becahse it bounces unpredictably. I lile this to exhaust and exercise my aussie. This has become his favorite toy ever. It charges fast too. When im feeling lazy this is good way to exercise my dog and enrich him. I also teach him commands using this ball as his treat or reinforcement. Definitely worth every penny

The best toy for my dogs
I was looking for a toy that could keep my dogs entertained themselves for a long time because with the traditional balls they usually get bored quickly, But I’ve definitely loved this toy , I have two dogs of different sizes and they have a lot of fun playing with it, the ball bounces and makes sounds that really catch their attention, the quality ea great, even though they bite it , it hasn’t been damaged and it is easy to carry it. It's amazing

Didnt last.
Didnt even last a day. My dog is a 40 pound lab mix and figured out how to unscrew the toy within the first couple of hours. He then detroyed the plastic screw system on the inside.

Super fun toy!!
This is such a fun toy! My dog loves running after it. The shape is perfect for a medium sized dog . He isn't into the round balls, but this football shape is easier for him. I love the automatic movement because it don't have to contactly be throwing it.

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.
