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.

Great deal, my face loves them
Love these and got them on a great deal! The retinol and vitamin c my face loves!! The hylalonic acid seems super similar to the vitamin c in formula, I use that one less.

My Skin Looks Brighter and More Hydrated
I use the vitamin C and hyaluronic acid in the morning after I wash my face, and then I use the retinol at night followed by my moisturizer. This routine has made a noticeable difference in my skin. I especially see it under my eyes and with my crow’s feet. My skin looks more hydrated, brighter, and overall healthier. On days I forget to bring the serums with me when I travel, I can actually tell. My skin feels more dehydrated and just looks more dull. When I’m consistent, my face looks more plump, glowy, and hydrated. That alone tells me these are working. They are also very lightweight and not greasy or oily at all. They absorb quickly into the skin and do not have a strong smell, which I really appreciate.

Would highly recommend
I was looking for something new and not crazy expensive. I have been using for 3 weeks now and I seeing good results. My skin is looking hydrated and feels awesome. I did also purchase the brightening moisturizer in addition to the serums as well as a night cream for my evening routine. Will continue to purchase. I do see that the droppers can stick but nothing that prevents you from using the product. There is very little scent which is a plus for my liking.
