Units and Dimensions by Rajaram Nityananda at https://www.youtube.com/watch?v=ZCwJuZloV0c If you are going to teach units, you should prepare them for a lifetime. Do not teach them how to use units as they are used now. Teach then how to look for and document units. And to prefer sources and groups who use units well. A

Launch Pad Astronomy: Neutron Stars, Pulsars and Magnetars at https://www.youtube.com/watch?v=tWsWcWAcK2U For the Internet Foundation, I had to add KiloTesla and MegaTesla to “commonly used units”. Yours is an early example of GigaTeslas, so there will be more. Gravitational energy density, magnetic energy density and many other kinds of energy density can all be interconverted now.

Beyond the Observable Universe at https://www.youtube.com/watch?v=mty0srmLhTk Infinite, pre-existing universe with a “local” big bang sized nova. Probably a gluon condensation nova when enough dense material accumulates to exceed the pressure needed to force gluons into compact lattices and structures. We will see more kinds of systems that are small, dark and powerful. If LIGO would

It was delayed a day after they tried to deliver it. It came and I understand. It is a BIG box and heavy. The box was beat up and scuffed but well packed and survived. The display popped out and was at the bottom of the box. I am 75 and still reasonably strong. but

At https://fletcher.house.gov/about/committees-and-caucuses.htm there is a text list of committees and caucuses. But no links, or explanations. I am sure “caucuses” show up all over House.gov and every place they are not “intelligent” with background and links immediately – it misses an opportunity to help citizens and people of the world understand who and what. I

Jolanda Jones, I was curious what a State Representative does. At 75, I finally have a little time to look. I tried writing to you on Facebook, but I think no one reads them. Acknowledging is a start. I found your House Bill “Relating to the inclusion of affordable housing as a qualifying project for

Adiabatic Flame Temperature at https://www.youtube.com/watch?v=AwgQvi1Y24o I would pre-heat the oxygen and fuel molecules electromagnetically. Then record the 3D volumetric temperature distribution, tracking flow of reactants. To start. And find the temperature dependent heat capacities data or models. To start. Calibrate and optimized the linked models. Track spectroscopic IR, VIS, thermal, UV, whatever is available. Share

At https://www.spectral-systems.com/technical-data-sheet/zns-zinc-sulfide/ the image for IR spectrum at https://www.spectral-systems.com/wp-content/uploads/2016/07/2-mm-ZnS-IR-Spectrum.jpg is missing. I am trying to find ZnS or ZnSe lenses to test an idea. But since it does not have to be durable, any solid low cost material transparent from 2-18 micron would do.
To: Fuzhou Hundreds Optics Inc 100Optics.com, Some very low light and NIR sensors might be able to pick up LWIR, out to thermal wavelengths 5-15 microns — if they used ZnSe lenses or GaAs. You could check pretty easily. I think the Sony Starvis might work but would need to use statistical methods and high

Why is this Beach in Southern California Radioactive? at https://www.youtube.com/watch?v=v0gIigW1HjA If you search ( oil well radioactive sludge ) you will find that radioactive materials are common in oil drilling. There will be drilled materials mixed with the drilling mud. I remember that propane has to be stored for a while because it’s molecular mass
