By Robert Gilmore

Alice is set to go into an entire new Wonderland. It's Quantumland--a form of highbrow enjoyment park, smaller than an atom, the place each one allure demonstrates a distinct element of quantum concept. There she'll meet an Emperor who thinks his new outfits into life, dance with the 3 Quark Brothers on the Particle MASSquerade, shuttle again in time (running into herself), and adventure all types of quantum results. Readers will find out about the Uncertainty precept, wave capabilities, the Pauli precept, and different elusive techniques.

Going Amiss in Experimental Research (Boston Studies in the Philosophy of Science)

Like any goal-oriented method, test is topic to many different types of disasters. those disasters have quite a few positive factors, looking on the details in their resources. For the experimenter those pitfalls may be refrained from and their results minimized. For the historian-philosopher of technology and the technology educator, however, they're instructive beginning issues for reflecting on technological know-how more often than not and medical technique and perform specifically. usually extra is realized from failure than from affirmation and profitable software. The id of mistakes, its resource, its context, and its therapy make clear either practices and epistemic claims. This publication indicates that it really is fruitful to deliver to gentle forgotten and misplaced disasters, topic them to research and examine from their ethical. The examine of mess ups, blunders, pitfalls and errors is helping us comprehend the best way wisdom is pursued and certainly generated. The booklet provides either old bills and philosophical analyses of mess ups in experimental perform. It covers subject matters akin to "error as an item of study", "learning from error", "concepts and lifeless ends", "instrumental artifacts", and "surprise and puzzlement".

This ebook may be of curiosity to historians, philosophers, and sociologists of technology in addition to to working towards scientists and technological know-how educators.

The Science of Photomedicine

Even supposing the heritage of photomedicine dates again millions of years, with even preliterate cultures appreciating the therapeutic houses of sun, for lots of staff within the self-discipline photomedicine is linked to the commentary approximately a hundred years in the past of Niels Finsen, a Danish health care provider. Finsen famous that individuals with tuberculosis who lived in Norway and who had little or no publicity to daylight frequently constructed facial lesions (lupus vulgaris) which might reduce and occasionally disappear throughout the summer season months.

Marine Science Frontiers for Europe

Europe is a continent with a excessive coast-to-surface ratio, and eu seas surround a extensive variety of settings and regimes. The sustainable improvement of residing and non-living marine assets, the safety of the marine setting and the availability of marine-based prone are serious to fiscal prosperity and to the standard of lifetime of ecu electorate.

Error as Historiographical Challenge: The Infamous Globule Hypothesis Jutta Schickore Introduction There is a repertoire of infamous errors that keep cropping up in standard histories of microscopy: the wheels attached to the head of rotifer, the little animals in semen, and the holes in the middle of blood corpuscles. The so-called ‘globule theory’ or ‘globule hypothesis’1 of organic matter occupies a prominent place on the list. This theory concerned the basic structure of bodily tissues. According to it, muscular and nerve tissue consist of tiny globules of regular size and shape.

Even though Weber’s refutation of the string-of-beads account convinced some, it did not persuade everybody. The situation remained inconclusive for several years. Most notably, and most bewildering to the modern reader is the fact that Friedrich Arnold advocated in his 1836 Handbook the string-of-beads account of nerve fibers and supplied impressive pictures even though he had underwritten Weber’s methodological cautions concerning light a few years earlier (cf. Arnold 1832, iv). The cases of Ehrenberg and Treviranus also show that Weber’s refutation of the string-of-beads account was not decisive.

When optically superior microscopes came into use, the practitioners were able to identify that theory as erroneous. John Baker’s comprehensive article, The Cell Theory, a Restatement, History and Critique of 1948 outlines the career of the globule hypothesis along these lines. For Baker, globulism was the ‘forerunner’ of cell theory. Baker located the origins of globulism in the seventeenth century. He identified a number of so-called ‘globulists’, the majority of them working around 1800, when globulism reached its ‘zenith’: Error as Historiographical Challenge: The Infamous Globule Hypothesis 29 Among them were Johann Friedrich Meckel, Everard Home and Francis Bauer, Carl Friedrich Heusinger, and Henri Milne Edwards.
