The Action Lab – Water bridges from Volts and Amperes, Temperature from Watts Grams and Seconds

The Action Lab: How Does a Floating Water Bridge Work? at https://www.youtube.com/watch?v=2IBiwfvXsKU NEVER say “high voltage” or “low voltage” and vague things. When you talk about electrical things, say how many Volts, how many Amperes, how many Hertz. You can put voltage and current meters on the screen so people set the values and can begin

Prasad Raju – Geophysical time series

Prasad Raju,   I suggest you use online resources to look at the data. There is a lot of seismometer and magnetometer data. There is meteorological data. If you just want sources of interesting signals, there is some good solar data (solar dynamics observatory), data from lots of astronomical and astrophysical surveys. Radio telescope data

Global Open Collaborative Worksites – speed development, pre-competitive research, open design and fabrication

Temperature-dependent elastic moduli of lead telluride-based thermoelectric materials Edgar Lara-Curzio, Thank you for the paper. I am reading it now. I wonder if open systems will eventually replace commercial solutions? The problem with commercial is they are usally too small. I try to track all open collaboration methods on the Internet, and have for the

Cadence – enabling global learning? Would tens or hundreds of millions work collaboratively for free to learn for free?

https://www.cadence.com/en_US/home/tools/system-analysis/computational-fluid-dynamics/pre-processing-meshing.html Is there an “intro to Cadence computational fluid dynamics” that tells the hardware requirements as a function of mesh size, time step size, precision? I wanted to teach basic properties of vertical flight through the atmosphere up to orbital velocities. I wanted to start with classical shapes, then add more complexity. Then let the

BrainTruffle Fluid Dynamics

BrainTruffle:  Fluid dynamics feels natural once you start with quantum mechanics at https://www.youtube.com/watch?v=MXs_vkc8hpY BrainTruffle, You need to use real measurements, on real systems, to match your different simulation strategies to real things. You are guessing by eyeball. You can get massive amounts of data from a number of places, or your own experiments. A billion

John Turner, particles with Coulomb and and gravity, Internet better practices for simulations and global collaborations

John Turner: N-Body Simulation with 70,000+ Particles at https://www.youtube.com/watch?v=fSeEg5XwGGo John Turner, I can think of many ways to make this easier for humans to see, to monitor for useful event and situations, to visual new things. First, you are showing position. You can also show velocity and acceleration, you can summarize statistic on changes, you can

Infrared Detectors, Detector sensitivity, “the Jones Unit”

https://www.researchgate.net/profile/Antoni-Rogalski I came across this entry for your book on ResearchGate but it does not seem to be connected to your profile. https://www.researchgate.net/publication/343958463_2D_Materials_for_Infrared_and_Terahertz_Detectors I am looking at infrared detector sensitivities to see which might be getting close to where they will pick up gravitational variations. Many new detectors now can pick up what is termed

THz imaging in quantum Hall conductors and superconductors. Gravitational energy density and gradients

Susumu Komiyama, I was looking for your paper, “Electron temperature of hot spots in quantum Hall conductors” and found this THz imaging paper on ResearchGate. I think at zero temperature the magnetic energy density and its gradients are important. “hot spots” are just part of it. I was looking at ways to push the fields
