  • Literature Compass Editing Humphry Davy's
    1 ‘Work in Progress in Romanticism’ Literature Compass Editing Humphry Davy’s Letters Tim Fulford, Andrew Lacey, Sharon Ruston An editorial team of Tim Fulford (De Montfort University) and Sharon Ruston (Lancaster University) (co-editors), and Jan Golinski (University of New Hampshire), Frank James (the Royal Institution of Great Britain), and David Knight1 (Durham University) (advisory editors) are currently preparing The Collected Letters of Sir Humphry Davy: a four-volume edition of the c. 1200 surviving letters of Davy (1778-1829) and his immediate circle, for publication with Oxford University Press, in both print and electronic forms, in 2020. Davy was one of the most significant and famous figures in the scientific and literary culture of early nineteenth-century Britain, Europe, and America. Davy’s scientific accomplishments were varied and numerous, including conducting pioneering research into the physiological effects of nitrous oxide (laughing gas); isolating potassium, calcium, and several other metals; inventing a miners’ safety lamp (the bicentenary of which was celebrated in 2015); developing the electrochemical protection of the copper sheeting of Royal Navy vessels; conserving the Herculaneum papyri; writing an influential text on agricultural chemistry; and seeking to improve the quality of optical glass. But Davy’s endeavours were not merely limited to science: he was also a poet, and moved in the same literary circles as Lord Byron, Samuel Taylor Coleridge, Robert Southey, and William Wordsworth. Since his death, Davy has rarely been out of the public mind. He is still the frequent subject of biographies (by, 1 David Knight died in 2018. David gave generously to the Davy Letters Project, and a two-day conference at Durham University was recently held in his memory.

  • Atomic History Project Background: If You Were Asked to Draw the Structure of an Atom, What Would You Draw?
    Atomic History Project Background: If you were asked to draw the structure of an atom, what would you draw? Throughout history, scientists have accepted five major different atomic models. Our perception of the atom has changed from the early Greek model because of clues or evidence that have been gathered through scientific experiments. As more evidence was gathered, old models were discarded or improved upon. Your task is to trace the atomic theory through history. Task: 1. You will create a timeline of the history of the atomic model that includes all of the following components: A. Names of 15 of the 21 scientists listed below B. The year of each scientist’s discovery that relates to the structure of the atom C. 1- 2 sentences describing the importance of the discovery that relates to the structure of the atom Scientists for the timeline: *required to be included • Empedocles • John Dalton* • Ernest Schrodinger • Democritus* • J.J.

  • Epistemology of Research on Radiation and Matter: a Structural View
    Kairos. Journal of Philosophy & Science 22, 2019 Center for the Philosophy of Sciences of Lisbon University Epistemology of Research on Radiation and Matter: a Structural View Isabel Serra (CFCUL) ([email protected]) Elisa Maia (CFCUL e IIBRC) ([email protected]) DOI 10.2478/kjps-2019–0016 Abstract The modern understanding of radiation got its start in 1895 with X-rays discovered by Wilhelm Röntgen, followed in 1896 by Henri Becquerel’s discovery of radioactivity. The development of the study of radiation opened a vast field of resear- ch concerning various disciplines: chemistry, physics, biology, geology, sociology, ethics, etc. Additionally, new branches of knowledge were created, such as atomic and nuclear physics that enabled an in-depth knowledge of the matter. Moreover, during the historical evolution of this body of knowledge a wide variety of new te- chnologies was emerging. This article seeks to analyze the characteristics of expe- rimental research in radioactivity and microphysics, in particular the relationship experience-theory. It will also be emphasized that for more than two decades, since the discovery of radioactivity, experiments took place without the theory being able to follow experimental dynamics. Some aspects identified as structural features of scientific research in the area of radiation and matter will be addressed through his- torical examples. The inventiveness of experiments in parallel with the emergence of quantum mechanics, the formation of teams and their relationship with technology developed from the experiments, as well as the evolution of microphysics in the sen- se of “Big Science” will be the main structural characteristics here focused. The case study of research in radioactivity in Portugal that assumes a certain importance and has structural characteristics similar to those of Europe will be presented.

  • John Dalton By: Period 8 Early Years and Education
    John Dalton By: Period 8 Early Years and Education • John Dalton was born in the small British village of Eaglesfield, Cumberland, England to a Quaker family. • As a child, John did not have much formal education because his family was rather poor; however, he did acquire a basic foundation in reading, writing, and arithmetic at a nearby Quaker school. • A teacher by the name of John Fletcher took young John Dalton under his wing and introduced him to a great mentor, Elihu Robinson, who was a rich Quaker. • Elihu then agreed to tutor John in mathematics, science, and meteorology. Shortly after he ended his tutoring sessions with Elihu, Dalton began keeping a daily log of the weather and other matters of meteorology. Education continued • His studies of these weather conditions led him to develop theories and hypotheses about mixed gases and water vapor. • He kept this journal of weather recordings his entire life, which later aided him in his observations and recordings of atoms and elements. Accomplishments • In 1794, Dalton became the first • Dalton joined the Manchester to explain color blindness, Literary and Philosophical which he was afflicted with Society and instantly published himself, at one of his public his first book on Meteorological lectures and it is even Observations and Essays. sometimes called Daltonism referring to John Dalton • In this book, John tells of his himself. ideas on gasses and that “in a • The first paper he wrote on this mixture of gasses, each gas matter was entitled exists independently of each Extraordinary facts relating to other gas and acts accordingly,” the visions of colors “in which which was when he’s famous he postulated that shortage in ideas on the Atomic Theory color perception was caused by started to form.

    RESEARCH REPORt 2010—2012 MAX-PLANCK-INSTITUT FÜR WISSENSCHAFTSGESCHICHTE Max Planck Institute for the History of Science Cover: Aurora borealis paintings by William Crowder, National Geographic (1947). The International Geophysical Year (1957–8) transformed research on the aurora, one of nature’s most elusive and intensely beautiful phenomena. Aurorae became the center of interest for the big science of powerful rockets, complex satellites and large group efforts to understand the magnetic and charged particle environment of the earth. The auroral visoplot displayed here provided guidance for recording observations in a standardized form, translating the sublime aesthetics of pictorial depictions of aurorae into the mechanical aesthetics of numbers and symbols. Most of the portait photographs were taken by Skúli Sigurdsson RESEARCH REPORT 2010—2012 MAX-PLANCK-INSTITUT FÜR WISSENSCHAFTSGESCHICHTE Max Planck Institute for the History of Science Introduction The Max Planck Institute for the History of Science (MPIWG) is made up of three Departments, each administered by a Director, and several Independent Research Groups, each led for five years by an outstanding junior scholar. Since its foundation in 1994 the MPIWG has investigated fundamental questions of the history of knowl- edge from the Neolithic to the present. The focus has been on the history of the natu- ral sciences, but recent projects have also integrated the history of technology and the history of the human sciences into a more panoramic view of the history of knowl- edge. Of central interest is the emergence of basic categories of scientific thinking and practice as well as their transformation over time: examples include experiment, ob- servation, normalcy, space, evidence, biodiversity or force.

  • 1 Classical Theory and Atomistics
    1 1 Classical Theory and Atomistics Many research workers have pursued the friction law. Behind the fruitful achievements, we found enormous amounts of efforts by workers in every kind of research field. Friction research has crossed more than 500 years from its beginning to establish the law of friction, and the long story of the scientific historyoffrictionresearchisintroducedhere. 1.1 Law of Friction Coulomb’s friction law1 was established at the end of the eighteenth century [1]. Before that, from the end of the seventeenth century to the middle of the eigh- teenth century, the basis or groundwork for research had already been done by Guillaume Amontons2 [2]. The very first results in the science of friction were found in the notes and experimental sketches of Leonardo da Vinci.3 In his exper- imental notes in 1508 [3], da Vinci evaluated the effects of surface roughness on the friction force for stone and wood, and, for the first time, presented the concept of a coefficient of friction. Coulomb’s friction law is simple and sensible, and we can readily obtain it through modern experimentation. This law is easily verified with current exper- imental techniques, but during the Renaissance era in Italy, it was not easy to carry out experiments with sufficient accuracy to clearly demonstrate the uni- versality of the friction law. For that reason, 300 years of history passed after the beginning of the Italian Renaissance in the fifteenth century before the friction law was established as Coulomb’s law. The progress of industrialization in England between 1750 and 1850, which was later called the Industrial Revolution, brought about a major change in the production activities of human beings in Western society and later on a global scale.
