Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

One way of fixing this is to make sure that more of that energy is reflected and never even penetrates the lower atmosphere. Solar geoengineering proposes to put particles into the upper atmosphere to increase its reflectivity and thereby reduce the temperature. In the episode I talk with Harvard’s David Keith about some of the technical aspects, which role this technique can play in the overall fight against climate change, some of the political challenges as well as current avenues of research.

Since the energy in the beam can be as high as the kinetic energy of a landing 747-400, designing and operating the dump is challenging.

Asteroid impacts or supervolcano eruptions come to mind. But since about the invention of the atomic bomb, humanity has been able to wipe itself out, adding self-made existential risks to the natural ones. Oxford philosopher Toby Ord argues in his book The Precipice that those risks are much more likely than the natural ones.

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 | Distance Metric | Blinded | Athena | C++ | Python | Effective Theory…

Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...
