CFR: Dark Matter & Modified Gravity Conference

Dark Matter & Modified Gravity Conference
6-8 February 2019
Aachen, Germany
Call for Registration (deadline 13 January 2019)

The Research Unit “Epistemology of the LHC” invites students and other scholars in philosophy, history and sociology of physics/science, as well as in physics, to register for the conference “Dark Matter & Modified Gravity”, taking place from 6 to 8 February 2019 at RWTH Aachen University, Germany.

Astrophysical and cosmological observations as well as explanatory gaps in the Standard Model of particle physics imply the existence of Dark Matter and/or a modification of our theory of space and time. A decision between the Dark Matter (DM) and Modified Gravity (MG) approaches is hampered by problems of underdetermination at different levels and of different kinds. The plethora of Dark Matter and Modified Gravity approaches, and the corresponding underdetermination, even in the light of the vast amount of relevant collider based and astrophysical observations, clearly illustrates the complexity of this scientific problem. On the other hand, the overlap of the collider and astrophysical domains may allow for reducing the underdetermination, thus leading to a simplification of the model landscape. One focus of this conference is Dark Matter searches at the Large Hadron Collider and the connection between LHC results and theories of gravity. We will address the question of different kinds of underdetermination, both in choosing between the two research programs of Dark Matter and Modified Gravity, and also in choosing between different models within each program. In particular, we aim to provide an assessment of the explanatory power and the explanatory gaps of the Dark Matter and Modified Gravity hypotheses, and the extent to which these might reduce the issues of underdetermination.

Research topics include, but are not limited to:
-Is a strict conceptual distinction between DM and MG justified? How does this relate to the distinction between matter and spacetime?
-What are the explanatory successes and failures of the DM research programme, and of the MG research programme? Which models of explanation are being employed by the respective programmes, and how do those relate?
-Sociology of the DM-MG debate
-How do data, constraints and explanations at the LHC, in astrophysics and cosmology relate? Could the LHC, in principle, confirm dark matter by itself?
-Virtues and vices of simplified (dark matter) models. Do simplified models explain?
-Hybrid models, fifth forces & exotic theories that are neither MG nor DM
-Connections between dark energy and DM/MG
-Novel predictions, fine-tuning and falsifiability

International Conference on Simplicities and Complexities
22-24 May 2019
Bonn, Germany
Call for Papers - Deadline: 15 January 2019

“Simplicities and Complexities" will take place from 22 to 24 May 2019 at the University of Bonn, Germany. It aims to bring together scientists and scholars from a spectrum of disciplines such as physics, biology, ecology, chemistry, and computational science, as well as from philosophy, sociology, and history of science. This conference is organized by the interdisciplinary, DFG- and FWF-funded research unit "Epistemology of the LHC".

Philosophers and scientists alike have often assumed simplicity to be an epistemic ideal. Some examples of theories taken as successful realizations of this ideal include General Relativity and Darwin's theory of Natural Selection. These theories influenced early and mid-20th century philosophers' understanding of the criteria successful scientific theories and practices had to meet, even when facing complex phenomena. However, this influence did not mean that the notion of simplicity was clear-cut. A suitable and encompassing definition of simplicity has yet to be developed. Some unanswered questions include: In what sense can and do physicists consider a theory, such as the Standard Model of elementary particle physics, as being sufficiently simple? How do ideals of simplicity differ when applied to disciplines other than physics? Biological concepts, for example, do not tend to refer to laws, whereas concepts from the social sciences frequently resort to notions of order and structure that are different from those of natural sciences. Are there, accordingly, simplicities (in plural) rather than a unified logic-inspired notion? Finally, are there cases where simplicity is simply a bad epistemic ideal, and not merely for the reason that it is often unreachable?

Throughout the 20th century the sciences have approached more and more complex phenomena, in tune with the increased social relevance of scientific knowledge. The perceived need to address complexity head-on has led to a broader reaction against simplification and reductionism within the sciences. However, if simplicity, in its various outfits, has proven an unreliable guide, what should it be replaced with? Looking at the various strategies of addressing complexity in the sciences and the disciplines reflecting upon them, it appears that the notion is at least as variegated as simplicity. To be sure, there exist measures of complexity as well as mathematical, empirical, or discursive strategies to deal with it, but they vary strongly from one discipline to another.


The aim of the conference is to analyze, differentiate, and connect the various notions and practices of simplicity and complexity, in physics as well as in other sciences, guided by the following questions:
* Which kinds and levels of simplicity can be distinguished (e.g. formal or ontological, structural or practical)? Which roles do they play and which purposes do they serve? Does simplicity, in a suitable reformulation, remain a valid ideal - and if so, in which fields and problem contexts? Or, instead, where has it been abandoned or replaced by a plurality of interconnected approaches and alternative perspectives?
* What about complexity? How is the complexity of an object of investigation addressed (represented, mirrored, negated, etc.) by the adopted theoretical and empirical approaches in different fields?
* Addressing complex problems, especially those relevant to society, requires institutional settings beyond the traditional research laboratory. How does the complexity of such settings relate to the complexity of epistemic strategies and of the problems themselves? In what sense can we trust the other players in a complex epistemic network?
* How should we conceive of the relation between simplicity and complexity? Are there alternatives to seeing complexity in opposition to simplicity? Does physics, in virtue of its history, maintain its special position in the contemporary debates on simplicity and complexity? What do reflections on the epistemic cultures of ecology, cultural anthropology, economics, etc. have to offer in terms of how simplicities and complexities can be balanced?

We invite contributors from a spectrum of disciplines, scientists and scholars reflecting on their respective and neighboring research fields, as well as historians, philosophers, and sociologists of science investigating the epistemologies, practices, and discourses of fellow epistemic communities. The conference will thrive on intense discussion surpassing disciplinary boundaries.

Motion re: Nova Scotia Bill 100

MOVED: In light of recent legislation in Nova Scotia, Bill 100, the Universities Accountability and Sustainability Act, given Royal Assent on May 11, 2015,
CSHPS deeply regrets the passage of this Act, because it:

• Threatens academic freedom and the integrity of academic institutions
• Fails to reflect adequately the contribution of universities to the economy and liberal society of Nova Scotia
• Does not properly recognize university governance structures and oversight mechanisms
• Fails to take into account the systemic underinvestment in PSE that has led to these issues
We therefore urge all governments to reject and repeal such legislation or draft regulations that remedy these concerns.

Manifeste de Manchester

À l’occasion du plus important congrès mondial rassemblant des historiens des sciences, des techniques et de la médecine, nous, administrateurs et membres de la Division internationale d’histoire des sciences et des techniques de l’Union internationale d’histoire et de philosophie des sciences et des techniques, proclamons :

(1) que la science, les techniques et la médecine constituent depuis des millénaires des traits constants de l’humanité et font partie intégrante de la société et de la culture dans le monde entier ;

(2) que les connaissances scientifiques, techniques et médicales sont un bien public ;

(3) que nous soutenons l’étude de la nature et nous efforçons de la rendre compréhensible à la communauté scientifique et au grand public par des recherches académiques scrupuleuses et par des actions de sensibilisation dans les nombreuses langues de la famille humaine ;

(4) que les recherches académiques sur les sciences, les techniques et la médecine doivent viser à une compréhension complète et nuancée de la croissance, du progrès, des problèmes et des perspectives de ces activités humaines essentielles. Ceci nourrit la conscience du fait que les sciences, les techniques et la médecine, lorsqu’elles sont correctement développées, sont un bien public ;

(5) que les historiens des sciences, des techniques et de la médecine peuvent jeter des ponts entre les diverses cultures par la collaboration et l’examen de perspectives, patrimoines et styles de pensée différents.

(6) que la compréhension de l’histoire des sciences, des techniques et de la médecine contribue positivement à l’enseignement de l’histoire générale ainsi qu’à celui des méthodes et du contexte des sciences, des techniques, et de la médecine ;

(7) que les produits des sciences, des techniques et de la médecine constituent une part essentielle du patrimoine matériel de l’humanité. Ces produits doivent être préservés, interprétés, et développés par des professionnels ayant une connaissance approfondie de leur signification culturelle.

En conséquence, dans le but d’une amélioration générale et d’une mise en œuvre de la connaissance, les participants réunis du 24e Congrès international d’histoire des sciences, des techniques et de la médecine, tenu à Manchester (Royaume Uni), en juillet 2013, déclarent :

1. L’histoire des sciences, des techniques et de la médecine doit être soutenue et financée de manière continue et régulière par les institutions publiques et privées de manière à garantir que les jeunes générations connaissent bien leur patrimoine scientifique, technique et médical tel qu’interprété par des historiens formés de manière appropriée.

2. L’histoire des sciences, des techniques et de la médecine mérite d’être intégrée de manière importante dans les programmes d’enseignement des écoles secondaires, des écoles supérieures et des universités. Les pratiques locales et nationales doivent guider cette intégration.
