"-philip kitcher, nature "in science as a process, david hull argues that the tension between cooperation and competition is exactly what makes science so successfulbecause of hull's deep concern with the ways in which research is actually done, science as a process begins an important project in the study of sciencemoreover, science as a process is one of the most compulsively readable books that i have ever encountered"-natalie angier, new york times book review"by far the most professional and thorough case in favour of an evolutionary philosophy of science ever to have been madeoxfam books & music crouch end "legend is overdue for replacement, and an adequate replacement must attend to the process of science as carefully as hull has donei share his vision of a serious account of the social and intellectual dynamics of science that will avoid both the rosy blur of legend and the facile charms of relativismit contains excellent short histories of evolutionary biology and of systematics (the science of classifying living things); an important and original account of modern systematic controversy; a counter-attack against the philosophical critics of evolutionary philosophy; social-psychological evidence, collected by hull himself, to show that science does have the character demanded by his philosophy; and a philosophical analysis of evolution which is general enough to apply to both biological and historical changebowler, archives of natural history "i have been doing philosophy of science now for twenty-five years, and whilst i would never have claimed that i knew everything, i felt that i had a really good handle on the nature of science, again and again, hull was able to show me just how incomplete my understanding wasthe claim that science is a process for selecting out the best new ideas is not a new one, but hull tells us exactly how scientists go about it, and he is prepared to accept that at least to some extent, the social activities of the scientists promoting a new idea can affect its chances of being accepted"-mark ridley, times literary supplement"hull is primarily interested in how social interactions within the scientific community can help or hinder the process by which new theories and techniques get acceptedhe applies the rules of evolution in nature to the evolution of science, arguing that the same kinds of forces responsible for shaping the rise and demise of species also act on the development of scientific ideasit is one of a distinguished series of books, which hull himself edits"-michael ruse, biology and philosophy see oxfam website for delivery information read morehull takes an unusual approach to his subject

Included on the ‘red’ side of the power strip is an effective rf filter, which prevents disruptive rf radiation in the power barthese are highly rated power supplies, this one is in excellent conditiontry a search for 'einstein the octopus power supply' on the net, although it seems an energy company called octopus comes up a lot in a searchthe octopus the power strip features eight power slots (four of which are filtered), a surge protector that protects all connected equipment, an rf filter and a phase detectoreinstein are still making these power strips, although today they have led displays, but the circuitry remains the sameof course, this filter utilizes reverse damping, which minimizes high-frequency interference of the connected components (in particular digital devices or devices with switching power supplies)made by the einstein audio company (germany) it is a very effective piece of kit as a power supply and should be able to service all separate components of a hifithis is around 11 years old! moving off-grid and so cant take this with metoo high a dc component in the network affects the function and limits the quality of playback of your hifi componentsthis is from the einstein site; the entire bar has an effective surge protection circuitit has 4 digital inputs (red) and 4 analogue (black)this voltage detector also recognizes disturbing dc voltages present in the network, if they are above a defined value (dc detect)these are quite expensive, cost me £350 new so this is a bargain**please note** this item is also listed elsewhere and will be withdrawn if sold there
