In dieser Episode geht es um Bionanotechnologie, also Nanotechnologie mit biologischen Mitteln, inbesondere DNA. Unser Gast ist Friedrich Simmel von der TU München. In der Episode besprechen wir biologische und physikalische Grundlagen, das Grundprinzip des Self Assembly sowie (potentielle) Anwendungsgebiete der Bionanotechnologie.

Diese Episode ist ein Gespräch mit Martin Randelhoff, Student an der TU Dresden, über verschiedene Aspekte von Verkehr und Mobilität. Dabei geht es um öffentlichen Nahverkehr und Individualverkehr, um aktuelle Trends, Forschungsergebnisse, Experimente und Verkehrsplanung. Aufgrund der Größe des Themas behandeln wir verschiedene Antriebstechniken nicht. Dies soll Thema einer separaten Episode werden.

In this episode we talk to Rainer Kresken of ESA ESOC Darmstadt about orbital mechanics and space flight dynamics. We have obviously addressed this topic in earlier episodes, this episode really diggs down deeper, and helped me understand the concepts and the challenges much better.

In dieser Episode geht es um Kernspin- oder Magnetresonanztomographie. Zu diesem Thema unterhalten wir uns mit Daniel Nanz vom Institut für Diagnostische und Interventionelle Radiologie des UniversitätsSpital Zürich. Daniel Nanz ist Naturwissenschaftler, und dementsprechend dreht sich die Episode vor allem um die physikalischen Grundlagen des Verfahrens sowie das Funktionsprinzip der entsprechende Geräte. Aber natürlich kommen medizinische Aspekte auch zur Sprache.

This episode wraps up our recent coverage on particle physics by discussing in some detail the recent discovery of a Higgs particle. Our guest in this episode is Kerstin Borras who heads up the CMS group at DESY. We recap the role of the Higgs very briefly, look in some detail at the two detectors CMS and ATLAS, discuss the importance of the famous five sigma and look at the process by which such a discovery is confirmed and (re-)checked.

In this 100th episode of omega tau we talk to Dr. Stephen B. Johnson about system health management, a set of techniques and processes used to improve system dependability. The episode is based on a book Stephen co-edited, and as a consequence of Stephen’s background, we use aerospace examples in this episode. We discuss the fundamental concepts such as functions, states and the state vector, failures and faults. We then discuss the influence of complexity on failures, as well as human involvement. We discuss means to prevent failures such as fault isolation, redundancy and model adjustment. We conclude the three-hour conversation by looking at the future of systems engineering and system health management with a particular focus on formal methods.

Episode 99 behandelt das Thema Lebensmittelchemie. Ich habe das Chemische und Veterinäruntersuchungsamt Stuttgart besucht und dort mit Dr. Carmen Breitling-Utzmann über Bestandteile von Lebensmitteln, Vorgänge bei der Lebensmittelverarbeitung, Schadstoffe und Analysemethoden gesprochen. Im Anschluss an das Gespräch durfte ich noch ein paar Labore anschauen und habe dabei insbesondere etwas über die Massenspektrometrie als Untersuchungsmethode erfahren.

This episode is a conversation about airborne wind energy. In particular, we talk to Roland Schmehl who leads a team of researchers and engineers at TU Delft who develop the Kitepower system. In this system, kites are automatically flown in a pumping pattern to extract energy from wind as an alternative to classical ground-based wind turbines. In the conversation we cover the benefits of airborne wind energy in general and of kites in particular and we cover in some detail how the Delft system works technically.
