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, 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

The Action Lab: What does the Strong Nuclear Force Look Like? at https://www.youtube.com/watch?v=Rx4lNihOT4U The Action Lab, Now take a beam of protons, grab them by their magnetic moment and spin them. Use the Block equations, or make new ones. Take another beam of protons or tritium or any of the “good fusion” candidates, they all

How Atomic Layer Deposition (ALD) works at https://www.youtube.com/watch?v=3ASNwXNXKsM At 0:32 you should be able to completely flatten the surface. Good practice for reaching picometer. Richard Collins, The Internet Foundation
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

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

The Action Lab: The energy required to heat 1 kilogram of water (1 liter) from 24 C to 100 C can be calculated by knowing the heat capacity of water in that temperature range. About 4184 Joules per kilogram per °C. Energy_Joules = (1 kg) * (4184 J/kg°C) * (76°C) = 318,384 Joules (1 Joule)

The Action Lab: What Is The Temperature in a Vacuum Chamber? Is it Hot, Cold or Neither? at https://www.youtube.com/watch?v=-hTAr2GkhpM There are three fields inside your box after the air is removed. There is an electromagnetic field in equilibrium with the walls of the box, and with the light and electromagnetic waves in the room. If you

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
