Real Capacitors at https://www.youtube.com/watch?v=hlmPFbHTHTw Sabrina Koffler, You could easily have shown the behavior of a few “real” capacitors as a function of frequency. And added a variable resistance and inductance to show the effects of changing those. Design, testing, measurement is all about numbers, data collection. More and more that also means models, algorithms, comparison between

The Internet, even on Twitter, is for everyone. Every person in the world should have access to global tools, data, models. Always include the open link. If APS cannot stay in business otherwise, tell me why. Nice paper, needs shared symbolic simulator. https://arxiv.org/abs/2106.13817 Collective effects on the performance and stability of quantum heat engines

@Sony Sony donated an Alpha 7S for a live webcam at Maunakea Subaru Telescope. Could Sony also help promote better Internet standards for lossless video? Look at these poor star pixels. Live stars need lossless formats. Global sharing for science data. https://www.youtube.com/watch?v=eH90mZnmgD4
You might never have heard of “Olber’s paradox”, but it is one of those perennial provacative items that gets served with most introduction to physics and astronophysics classes. For the lecturer to strut their stuff and appear learned. Olber is Heinrich Wilhelm Olbers (1758-1840) and the link is https://en.wikipedia.org/wiki/Olbers%27_paradox I like to watch the night

Physics Magazine @PhysicsMagazine 8h Simulation videos illustrate how changing different parameters of the system alters how well two fluids mix together when stirred. (For the stirrers, tadpole and teeth shapes are best). Read the story by @astrogasparini. https://physics.aps.org/articles/v15/s104 https://pic.twitter.com/UFWWcsHeHu Replying to @PhysicsMagazine @PhysRevFluids and @astrogasparini Effectively Mixing Two Fluids at https://physics.aps.org/articles/v15/s104 If only the simulations

Nanofocused x-ray photon correlation spectroscopy – Data link broken thru DOI.org https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.4.L032012 Fivos Perakis, I was reading your article and wanted to look at the data, but the link is broken. And the DOI system form to report the error is also broken. The DOI form appears but accepts no input. In the PDF: “The

The Planck Temperature – Absolute Hot: What is the hottest temperature possible https://www.youtube.com/watch?v=ofzlBP6_5iw If you had a $Thank button, I would have sent you a donation to encourage you to keep going and work harder. You have the right kind of curiosity, but you need to keep digging and read harder papers. Tone down “strange”

https://twitter.com/InnovationPhys https://t.co/OFNXFJh4oi @InnovationPhys You are too focused on topics suitable for single person dissertations and individual performance. Need to coordinate and encourage solutions to global issues and opportunities. Answer “Where does this apply?” and encourage open global sharing of models and data.
Integrated Water Strategies: Thinking Outside The Pipe at https://www.youtube.com/watch?v=h1Lq7COGD2Q These seem to be very expensive methods. Do you have a cost breakdown? Homes, schools, businesses, small farms, abandoned land, landfills, poor counties, poor cities, poor countries. Nothing wrong, except the world and climate change is very large. Teaching only methods – without also teaching how
