"Gender- und diversity-informierte Lehre in der Physik"
"Gender and diversity aspects in physics education"

When: Tuesday, 03.12.2019, 14:30 -16:30 h
Where: University of Bremen, NW1, S1360

Speaker: Prof. Dr. Helene Götschel (Hochschule Hannover)

The event was organised by the ZKFF in cooperation with the dean's office and the decentralised women's representatives of the department 1-Physics/Electrical Engineering.

The talk will be held in German.

Trotz des vorherrschenden Diskurses der Gleichbehandlung und Bedeutungslosigkeit von Gender in Physik sind eine Diskrepanz im Geschlechterverhältnis und Geschlechterunterschiede in den Narrationen der Physik wahrnehmbar. Diesen Ungleichheiten wird meist mit Kontext- und Begleitmaßnahmen zur Gleichstellung begegnet, etwa wenn junge Frauen in einem Schnupperkurs zu einem MINT-Studium ermutigt werden. Nachhaltige strukturelle Veränderungen hingegen, etwa zur Veränderung der Fachkultur Physik, werden bislang kaum umgesetzt. Eine Ausnahmebilden hier Maßnahmen zur Verbesserung der Qualität der Lehre. Im Vortrag werden einige Handlungsorientierungen vorgestellt, mit denen die (Re-)Produktion von Ungleichheit in der Physiklehre herausgefordert werden kann. Zunächst wird diskutiert, welche Impulse sich aus der Literatur zu „Gender und Diversity in der Lehre“ für die Physik gewinnen lassen. Anschließend wird anhand von Beispielen aus der Lehrpraxisvorgestellt, wie eine gender- und diversity-informierte Physikvorlesung gestaltet werden kann. Zu den Strategien, die Differenzen überwinden und Stereotype aufbrechen können zählen dabei das Hinterfragen von Image und Selbstverständnis der Physik, die Kontextualisierung physikalischen Wissens, die Verwendung von Gender und Diversity berücksichtigenden Lehrmaterialien und der kritische Blick auf materiell-diskursive Choreografien physikalischer Demonstrationsexperimente.

Do Black Holes Exist? - The Physics and Philosophy of Black Holes

Where:Bad Honnef, Germany
What:The evidence for the existence of Black Holes received a strong boost with the direct detection of gravitational waves which perfectly fit to the simulation of the merger of two Black Holes with masses of around 30 to 40 Solar masses. Further evidence for their existence is given by the observation of stars around the Sagittarius A*, the center of our galaxy, the observation of radiation from accretion disks around many massive galactic Black Holes, high energetic jets emerging from the near vicinity of Black Holes. We are also waiting for further evidence based on new observations with the Event Horizon Telecope and the Black Hole Cam. However, despite these overwhelming observations there is still the question of the interpretation: How shall we deal with the situation that no Black Hole can be observed directly? This question will be discussed by experts from the observations, from the mathematical and theorerical aspects of Black Holes, as well as from the philosophy of sciences.
  • the current status of observations and future plans
  • Black Hole solutions of gravitational field equations and their properties
  • Physical effects in the vicinity of Black Holes
  • the philosophy of Black Holes

IAU Symposium 324: New Frontiers in Black Hole Astrophysics

At Cankarjev dom, Ljubljana, Slovenia



A key unsolved issue in modern astrophysics is how black holes accrete matter and subsequently launch focused jets of material to speeds close to that of light, releasing copious energy in the process. This occurs over many orders of magnitude in mass, size and timescale in a wide range of astrophysical objects but the mechanisms converting gravitational potential energy into radiated energy remain poorly understood. These systems also provide unique laboratories for the study of physics in extreme conditions such as strong gravity, large magnetic fields, ultra-relativistic particle acceleration and, as such, may also provide valuable probes of space-time and tests of fundamental physics.

The goal of this symposium is to bring together observational and theoretical experts in the astrophysics of black-hole driven systems to discuss the current state-of-the-art in accretion, jet formation and acceleration and emission mechanisms - and more generally source physics, with theoretical physicists who aim to use astrophysical objects to test current theories of gravity and ultimately unified theories of quantum gravity.

This symposium is timely both scientifically and in terms of upcoming technology whose advances across the electromagnetic spectrum and beyond to multimessenger signature such as gravitational waves and neutrinos are coming of age. By 2016, the new generation of gravitational wave detectors will be operational, improved sensitivity in neutrino detectors will be available, the multiwavelength community will have an impressive suite of ground- and space-based facilities covering a wide range of energy bands and timescales, and the theoretical astrophysics communities will be providing new testable predictions from advances in hydrodynamic, magnetohydrodynamic and plasma cell-based simulations.

Leading up to major new facilities such as the Cherenkov Telescope Array, the Large Synoptic Survey Telescope and the Square Kilometre Array coming on line from 2018 onwards, this symposium will provide a stimulating environment for a new generation of astrophysicists to connect with, learn from and present their work to a unique and diverse combination of world-leading astrophysicists and physicists with a common interest in black holes and their applications.

More broadly, black holes hold much appeal for the lay audience; building on the University of Ljubljana's expertise and Prof. Gomboc's leadership in public outreach in Slovenia since the International Year of Astronomy 2009 and in organising the National Astronomical Competition for Schools, the organisers will maximise the exposure of the symposium science to the general public directly and through the popular press, as well as to the Slovenian parliament, and through the Teachers Workshop.




1. Similarity and diversity of black hole systems

2. Gamma Ray Bursts; their physics and use as probes of elementary particle physics

3. Tidal Disruption Events; prediction, discovery and implication

4. Active Galactic Nuclei; high-mass black hole systems as laboratories for extreme physics 

5. Tests of fundamental theories of physics using black hole systems across the mass spectrum

6. Technology drivers and future capabilities

Ultracold Quantum Gases - Current Trends and Future Perspectives

Where:Bad Honnef, Germany
What:Since the first experimental realization of Bose-Einstein condensation in ultracold atomic gases in 1995, there have several substantial breakthroughs. Today, systems of bosonic or fermionic quantum gases allow for a very high level of experimental control concerning all ingredients of the underlying many-body Hamiltonian. The underlying trapping geometry can be designed to be harmonic, anharmonic or, recently, even box-like which mimics a quasi-uniform potential. Furthermore, the shape of the two-particle interaction can be modified from the short-ranged and isotropic contact interaction to the long-ranged and anisotropic dipolar interaction. In particular the possibility to tune the strength of the contact interaction to basically any attractive or repulsive value with the aid of the Feshbach resonance allows nowadays to probe quantum fluids in regimes and under conditions hitherto unavailable. Since 2011 it has even been experimentally achieved to also tune the kinetic energy of the many-body Hamiltonian by producing synthetic spin-orbit coupling. This nourishes the prospect to generate for neutral atoms abelian gauge fields, as they appear in electromagnism for charged particles, but also non-abelian gauge fields, as they occur in the standard model of elementary particle physics. Therefore, quantum gases are considered to be ideal quantum simulators, i.e. they are best capable to simulate difficult quantum problems in condensed matter physics and other fields of physics in the sense of Richard Feynman from 1982.

Wann:19:00 Uhr
Sprecher/in:Prof. Dr. Dieter B. Herrmann 
Titel:"Das Urknall-Experiment - auf der Suche nach dem Anfang der Welt"
Abstract:Im Herbst 2009 ist in Genf die "Größte Maschine aller Zeiten" in Betrieb genommen worden: Der Large Hadron Collider (LHC). Nach einer längeren Pause wurde er 2015 wieder hochgefahren - auf seine maximale Leistung. Subatomare Teilchen prallen dort mit nahezu Lichtgeschwindigkeit aufeinander. Die Forscher hoffen, damit dem "Geheimnis des Urknalls" und somit der Entstehung des Universums auf die Spur zu kommen. Wie ist das möglich?

Der Vortrag berichtet, unterstützt von faszinierenden Bildern, über die gegenwärtigen Vorstellungen von der Lebensgeschichte des Weltalls und über das Standardmodell der Mikrowelt. Auf diese Weise wird für den Hörer verständlich, welcher Art die Experimente am LHC sind und wie sie unsere Vorstellungen über unsere Welt und damit über uns selbst verändern, erweitern und bereichern können.

Wo:Eberhard Karls Universität Tübingen, Physikalisches Institut, Experimentalphysik II
Wann: 16:15 Uhr
Sprecher/in:Prof. em. Rudolf P. Hübener
Titel: "Die Geburt der Quantenphysik - Boltzmann, Planck, Einstein, Nernst und andere"
Abstract:Wegen des rapiden Anstiegs der künstlichen Beleuchtung am Ende des 19. Jahrhunderts bestand damals ein großer Bedarf an quantitativen optischen Daten und einem anerkannten Lichtmaß. Deshalb wurde im optischen Laboratorium der Physikalisch-Technischen Reichsanstalt in Berlin die spektrale Verteilung der Lichtintensität über einen großen Frequenzbereich genau gemessen. Diese neuen Daten konnte mit den vorliegenden Modellen nicht erklärt werden. Zwischen Oktober und Dezember 1900 gelang Max Planck die Ableitung seines berühmten Strahlungsgesetzes auf der Grundlage von Boltzmann's Wahrscheinlichkeits-Interpretation der Entropie. Als zentralen neuen Ansatz führte Planck die Quantisierung der Strahlungsenergie durch die diskreten Energie Elemente hv ein, mit der universellen Konstanten h. Während Planck die volle Bedeutung der neuen Quanten Physik fast 10 Jahre lang nicht akzeptierte, waren es Albert Einstein, der 1905 mit seinen Lichtquanten und 1906 mit seiner Quantisierung der Gitterschwingungen in Kristallen, und wenige Jahre später Walther Nernst mit seinen Messungen der spezifischen Wärme, die die neuen Ideen der Quanten Physik stark vorantrieben.

Vortragsreihe Hochschule Bremen  

Wo:HS-Bremen Werderstraße
Sprecher/in:Prof. Dr. Jürgen Blum 
Titel:"Was können uns Kometen über ihre Entstehung verraten?"
Abstract:Die Erscheinung eines Kometen am Himmel ist viel auffälliger als der relativ kleine und dunkle feste Körper, der sie bei seiner Annährung an die Sonne hervorruft. Dennoch zählen Kometenkerne zu den interessantesten und wissenschaftlich wichtigsten Körpern des Sonnensystems, um dessen Entstehung zu beschreiben. Die Bilder der Raumsonde Rosetta haben uns in den letzten Monaten vielfältige Eindrücke vom nur wenige Kilometer großen Kometen Tschurjumow-Gerasimenko gegeben. Was können wir aber durch das Studium von Kometen über deren Entstehung und die Bedingung im jungen Sonnensystem lernen? Der Vortrag wird sich dieser Frage widmen und Einblicke in die aktuelle Forschung der Planetenentstehung  erlauben. Dabei kommt den Kometen eine Sonderrolle zu, denn sie zählen zu den am wenigsten veränderten Körpern des Sonnensystems, weil sie den Großteil der Zeit  seit ihrer Entstehung vor gut viereinhalb Milliarden Jahren in großer Entfernung zur Sonne verbracht haben und somit weder durch hohe Temperaturen noch durch Kollisionen prozessiert worden sind. Die Tatsache, dass sie beim Flug durch das innere Sonnensystem große Mengen an Staub auswerfen und somit für uns zu einem manchmal brillianten Schauspiel am Himmel werden, erlaubt es uns, mehrere sonst möglich Entstehungsszarien auf nur noch eines zu reduzieren: Die für uns sichtbaren Kometen müssen durch den gravitativen Kollaps einer Staubwolke aus millimeter- bis zentimetergroßen Staubteilchen entstanden sein.

Lecture University of Oldenburg

Where:University of Oldenburg
Speaker:Dr. Ralf Lehnert 
Title:"Does Relativity Theory Hold Exactly?" 
Abstract:Relativity Theory is a cornerstone of physics. Since its conception over a centruy ago, it has been scrutinized experimentally with ever increasing precision, but no credible evidence for departures from its underlying symmetry . Lorentz invariance - has been found to date. However, recent theoretical research has established that minute violations of Lorentz symmetry can be accommodated in various approaches to physics beyond the Standard Model. This seminar provides a brief overview of our group's efforts in this research field. A variety of mechanisms for Lorentz breakdown are reviewed, the effective-field-theory test framework for the emerging low-energy effects is introduced, and a number of present-day and near-future experimental measurements in this context are surveyed.

Abstract:In his lecture he will introduce the field of precision measurements using atom interferometers and present state-of-the-art experiments featuring atomic sensors with applications in gravimetry and geodesy. He will also present recent efforts deployed in the field of satellite geodesy with atomic interferometric antennas. 

Abstract: Thanks to their accuracy and long term stability, inertial sensors based on atom interferometry offer interesting perspectives in space, for applications in fundamental physics and geodesy. In particular, such atomic sensors are appealing candidates for ultrasensitive measurements of acceleration in future space missions. In my talk, I will present the advantages of these sensors with respect to conventional accelerometers, and show that they can compare favourably in terms of performance with their classical counterparts. I will in particular present an ongoing ESA study of embarking cold atom gradiometers in a dedicated satellite, with expected senstivities in the mE/Hz^(1/2) range. I will discuss some of the technical challenges one has to cope with in order to improve our knowledge of the Earth gravity field using this technology.

Astronomievortrag: Die Herkunft des Lebens

Wo:HS-Bremen Werderstraße; Hörsaal B120
Sprecher/in:Prof. Dr. Wolfram Thiemann (Universität Bremen*)
Titel:"Herkunft des Lebens - hat das ehrgeizige Projekt ROSETTA mit der Erforschung der Oberfläche des Kometen 67P/Churyomov-Gerasimenko uns in der Beantwortung dieser Frage weitergebracht?" 
Abstract:Wie entstand das Leben auf unserem Planeten Erde? Welche Bausteine des Lebens sind nötig, um Lebensformen, wie wir sie bisher nur von der Erde kennen, hervorzubringen? Prof. Thiemann geht der Frage nach, ob diese Lebensbausteine durch frühe Einschläge von Kometen zu uns gebracht worden sein könnten. Die Schlüsselrolle spielt hier die Rosetta-Mission - und die spektakuläre Landung von PHILAE auf dem Kometen 67P/Churyomov-Gerasimenko (auch genannt "Chury"), die vor gut einem Jahr für große Begeisterung und Aufregung sorgte. Ein Experiment, das auf dem Kometen diese Ur-Bausteine des Lebens nachweisen sollte, ging anders aus, als es urpsrünglich geplant war. Welche Erkenntnisse konnten wir gewinnen, und sind wir - wie der Untertitel dieses Vortrages besagt - der Frage nach dem Ursprung des Lebens auf der Erde indessen näher gekommen? Diesen und weiteren überaus faszinierenden Fragen nach dem Ursprung des Lebens - nach wie vor eines der größten Rätsel im Universum - geht Prof. Thiemann in diesem Vortrag nach. 

Wir freuen uns auf eine spannende Präsentation, und darauf, ihm noch einige Fragen stellen zu können.

A Century of General Relativity

Where:Harnack House, Berlin, Germany
The conference is thus scheduled to take place almost exactly 100 years after the
submission of Einstein's paper, and in a location where Einstein regularly
lectured between 1915 and 1931, not too far from where
the breakthrough actually happened. The scientific program is meant
to cover all aspects of modern General Relativity and its future outlook.
