This article is a case study and rhetorical analysis of a specific scientific paper on a computer simulation in astrophysics, an advanced and often highly theoretical science. Findings reveal that rhetorical decisions play as important a role in creating a convincing simulation as does sound evidence. Rhetorical analysis was used to interpret the data gathered in this case study. Rhetorical analysis calls for close reading of primary materials to identify classical rhetorical figures and devices of argumentation and explain how these devices factor in the production of scientific knowledge. This article describes how abduction, dilemma, compensatio, aetiologia, and other tactics of argumentation are necessary in creating the simulation of a supernova. Ultimately, the article argues that rhetorical mechanisms may be responsible for making some simulations better and more sound than others.

Public images of scientific researchers –as reflected in the popular visual culture as well as in the conceptions of the public- combine traditional stereotypic characteristics and ambivalent attitudes towards science and its people. This paper explores central aspects of the public image of the researcher in Greek students’ drawings. The students participated in a drawing competition held in the context of the ‘Researcher’s Night 2007’ realized by three research institutions at different regions of Greece. The students’ drawings reveal that young people hold stereotypic and fairly traditional and outdated views of scientists and scientific activity. Research institutions are faced with the challenge of establishing a sincere and fertile dialogue with society to refute obsolete and deceiving notions and to promote the role of researchers in society.

Museums have a great potential to facilitate the political engagement of citizens, intended not in the sense of taking part to the “party politics”, but as full participation in the systems that define and shape society.

Luckily enough, more democracy is always called for. Even in countries that can truly be described as democratic. And democracy (which is a constant reference in these pages) is increasingly related to knowledge, be it about whether growing GMOs, starting nuclear energy production or allowing the choice of a child’s gender through IVF techniques. The need to make democratic decisions on controversial issues, which increasingly imply scientific and technological knowledge, comes from the bottom, as citizens voice – sometimes even vehemently – the desire to express themselves.

The first 18 volumes of the International Scientific Series published in both London and New York were reviewed to assess their contribution to transatlantic communication of popular science. The dominant flow of ideas was westwards on topics such as science versus religion, empiricism in psychology, survival of the fittest, jurisprudence versus mental illness, economics and development of cinematography. There was an eastward flow in philology. The preparation of volumes was rushed and many authors merely expanded previous notes, articles and pamphlets. Commercial and idealistic motives conflicted. There were disagreements among authors. Despite all this, the series had a lasting effect on social thought.

This article sums up key results of a web-based questionnaire survey targeting the members of the Danish Science Journalists' Association. The association includes not only science journalists but also other types of science communicators. The survey shows that science communicators have a nuanced and multidimensional view on science communication, science, and technology. Science communicators are thus more than the "mountain guides" of science, as a recent definition describes it. The survey respondents are not just interested in helping the public at large to a wider recognition of scientific knowledge, but also want to contribute to democratic debate and social legitimisation of science and technology. The respondents exhibit a certain amount of optimism in relation to science and technology, yet also take a sceptical stance when confronted with overly positive statements regarding science and technology. Finally they have a predominantly social constructivist perception of science and technology when it comes to external relations to society, while they lean towards a hypothetical-deductive science understanding when it concerns the internal dynamics of science

“From Earth to the Universe” (FETTU) is a collection of astronomical images that showcase some of the most popular, current views of our Universe. The images, representing the wide variety of astronomical objects known to exist, have so far been exhibited in about 500 locations throughout the world as part of the International Year of Astronomy. In the United States, over 40 FETTU exhibits have occurred in 25 states in such locations as libraries, airports, nature centers, parks and college campuses. Based on preliminary evaluations currently underway, this project – a large-scale, worldwide astronomy outreach in non-traditional locations – has unique opportunities and implications for informal science learning. We present some early findings from the observational section of the exhibit’s formal evaluation in five selected locations in the U.S. and U.K., including emphasis on inter-organizational networking, visitor attention and participant make-up as well as generative aspects of the exhibit.

In this essay, I argue that the rise of personal genomics is technologically, economically, and most importantly, discursively tied to the rise of network subjectivity, an imperative of which is an understanding of self as always already a subject in the network. I illustrate how personal genomics takes full advantage of social media technology and network subjectivity to advertise a new way of doing research that emphasizes collaboration between researchers and its members. Sharing one’s genetic information is considered to be an act of citizenship, precisely because it is good for the network. Here members are encouraged to think of themselves as dividuals, or nodes, in the network and their actions acquire value based on that imperative. Therefore, citizen bioscience is intricately tied, both in discourse and practices, to the growth of the network in the age of new media.

This introduction presents the essays belonging to the JCOM special issue on User-led and peer-to-peer science. It also draws a first map of the main problems we need to investigate when we face this new and emerging phenomenon. Web tools are enacting and facilitating new ways for lay people to interact with scientists or to cooperate with each other, but cultural and political changes are also at play. What happens to expertise, knowledge production and relations between scientific institutions and society when lay people or non-scientists go online and engage in scientific activities? From science blogging and social networks to garage biology and open tools for user-led research, P2P science challenges many assumptions about public participation in scientific knowledge production. And it calls for a radical and perhaps new kind of openness of scientific practices towards society.

In this commentary, we collected three essays from authors coming from different perspectives. They analyse the problem of power, participation and cooperation in projects of production of scientific knowledge held by users or peers: persons who do not belong to the institutionalised scientific community. These contributions are intended to give a more political and critical point of view on the themes developed and analysed in the research articles of this JCOM special issue on Peer-to-peer and user-led science. Michel Bauwens, Christopher Kelty and Mathieu O'Neil write about different aspects of P2P science. Nevertheless, the three worlds they delve into share the "aggressively active" attitude of the citizens who inhabit them. Those citizens claim to be part of the scientific process, and they use practices as heterogeneous as online peer-production of scientific knowledge, garage biology practiced with a hacker twist, or the crowdsourced creation of an encyclopedia page. All these claims and practices point to a problem in the current distribution of power. The relations between experts and non-experts are challenged by the rise of peer-to-peer science. Furthermore, the horizontal communities which live inside and outside the Net are not frictionless. Within peer-production mechanisms, the balance of power is an important issue which has to be carefully taken into account.
