To conclude our detailed look at the ATLAS experiment, this episode looks at the computing infrastructure. We start out with the trigger systems that decide, very quickly, whether the data from a particular collision is worth keeping. We then discuss the reconstruction of the event, the simulation needed to understand the background as well as the LHC Grid used distribute data and computation over the whole planet. Our guest is CERN'n Frank Berghaus.

In dieser Episode erklärt und Sebastian Triesch die Photosynthese funktioniert. Wir besprechen die grundlegenden Mechanismen, Aspekte der Entwicklung sowie verschiedene Varianten die man heute in Pflanzen findet. Wir reden außerdem über die Forschung zu Photosynthese beim Exzellenzcluster CEPLAS wo Sebastian promoviert. Am Ende sprechen wir auch ein bisschen über Gentechnik im allgemeinen.

In dieser Episode spreche ich mit meinem Bruder Mathias über seine Arbeit als Notfallsanitäter beim DRK Heidenheim-Ulm. Wir sprechen über die Struktur und Organisation des Rettungsdienstes in Deutschland, Rollen und Aufgaben, sowie typische Szenarien bei Hausnotfällen und bei Verkehrsunfällen. Am Schluss reden wir darüber, wie Corona die Arbeit verändert (hat).

Guests: Philipp Windischhofer   Host: Markus Voelter   Shownoter: Andy Joiner After understanding the history and development of ATLAS (and covering the LHC and particle physics in general) in previous episodes, we are now at the point where we can try to understand how a scientist uses the data produced by one of these large detectors and make sense of it. This is what we’ll do in this episode with physicist (and listener) Philipp Windischhofer. If you want to learn even more, you can check out these links provided by Philipp or read the last chapter of the book :-) Some additional material supplied by Philipp: All ATLAS physics papers The Higgs analysis paper we spoke about in the episode The press release that goes with it Public lecture by my favourite physicist on “why the Higgs has to exist” On the hierarchy problem ROOT data analysis framework Introduction 00:03:23 Philipp Windischhofer | Particle Physics | University of Oxford | Atlas Collaboration | Atlas Detector (Episode 030 – The Large Hadron Collider)  | Large Hadron Collider (LHC) | CERN | Higgs Boson (Episode 093 - Standard Model)  | Other episodes on particle physics Particle Physics 00:05:03 Special relativity | Quantum Mechanics | Mass | Charge | Spin | Symmetry | Angular Momentum | Quantized | Graviton | Gravitational Waves | Quark | Color Charge | Strong Interaction | Weak Charge | Weak Interaction | Four Point Interaction | Wave-Particle Duality | Virtual Particles | Quantum Field Theory | Matter Particles | Force-Carrier Particles | Boson | Fermion | UA1 Experiment | UA2 Experiment | Cross Section | Mexican Hat Potential | Spontaneous Symmetry Breaking | Sigmas | FCC | GeV | Hierarchy Problem Atlas Experiments 00:59:13 Collision | Momenta | Proton | Sub-detectors | Interaction-point | Pixel Detector | Magnetic Field | Gas Based Tracking Detector | Transition Radiation Tracker (TRT) | Calorimeter | Electromagnetic Calorimeter | Hadronic Calorimeter | Muon System (Gas Detectors) | Right-hand Rule | ~2MB data per event | Bunch | Visualizations | Event Reconstruction | Energy Deposits | Extrapolate | Noise | Combinatorics | Tracking | Tracklet | Kalman Filter | Data Fusion | Showers | Jet | Jet Clustering Algorithm | Pileup | Calibration | Model | Integration | Simulation | CAD Model | Bootstrapping | Monte Carlo Methods | Numerical Methods Physics in ATLAS 01:55:28 Decay | Decay Rate | Boosted | Associated Production | Candidates | ROOT file | Degrees of Freedom | Plot/Histogram | Distribution | Maximum Likelihood Fit | Discretize | Artificial Neural Networks | Boosted Decision Tree | Discriminant[...]

ATLAS is one of the two general-purpose experiments at the LHC. It has been conceived, designed, and built over decades by hundreds of scientists and engineers from dozens of countries and hundreds of organizations. My guest, Peter Jenni, has been the head of the ATLAS collaboration for most of this time. In this episode we talk about science and engineering, but mostly about organizational aspects and the "community management" necessary to get such a magnificent machine off the ground.

The Lockheed F-35 Lightning II is going to be more or less what the F-16 and F-18 are today: the backbone of the US and NATO land and sea-based air forces. It is a multi-role fighter, and one of its versions has the capability to take off with a ver[...]

The Lockheed F-35 Lightning II is going to be more or less what the F-16 and F-18 are today: the backbone of the US and NATO land and sea-based air forces. It is a multi-role fighter, and one of its versions has the capability to take off with a very short roll and land vertically. Tucker "Cinco" Hamilton is a test pilot who has flown all three versions of the jet. In this episode we talk about flying this fifth-gen fighter and about some aspects of the testing program.

Im Kontext von COVID-19 hören wir alle ständig Begriffe rund um unser Immunsystem und wie es Viren bekämpft - oder auch nicht. Wir dachten uns, dass wir die Grundlagen des Immunsystems etwas besser verstehen sollten. Unser Gast, Ulrich Sack, ist Professor am Uniklinikum Leipzig und dort für Immundiagnostik zuständig. Wir haben uns mit ihm über die Funktionsweise des Immunsystems unterhalten, sowie über dessen Erkrankungen.

In light of the current situation, we have decided to record a couple of episodes that cover some of the relevant background in terms of biology, medicine and healthcare. In this first episode we discuss emergency care and intensive care with a special focus on ventilation. We discuss these topics in general, and also specifically to COVID-19. Our guest, Kimon and Junad, are both practicing doctors and have practical experience with these topics.

A major component of particle accelerators like the LHC are the actual accelerators; the current approach relies on radio frequency cavities. However, their acceleration gradient, measured in Volts per meter, is limited. This means that future accelerators, especially linear ones, will become longer and longer to reach the desired energies. A new approach to particle acceleration relies on plasma wakefields, this technology can deliver orders of magnitude more acceleration per distance. AWAKE is a proof of concept experiment at CERN that uses proton beams to produce the wake field. In this episode we chat with Edda Gschwendtner, the leader of this project.

Over the last two years, Markus wrote a book about some of the repeated topic covered on omega tau: SOFIA, Enterprise, Aerospace, Gravitational Waves, Telescopes, Models and Particle Physics. The book, called Once You Start Asking is now available as an ebook, with the softcover edition forthcoming. In this episode, Nora and Markus discuss the book and its history.
