Posted on my Facebook about Olbers paradox and an infinite universe

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 I like to watch the night

Twitter about lack of teachers for Texas – Lifetime learning for everyone is possible and desireable

Texas Tribune @TexasTribune 13h Texas has had a teacher shortage for years. However, a number of recent issues have placed teachers at the front lines — and are pushing them to their limits and out of the job. Here’s what you need to know: Replying to @TexasTribune Your 2020 Texas pop is 29.6 M.

Twitter simulation of fluids stirred by pointed paddles

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. Replying to @PhysicsMagazine @PhysRevFluids and @astrogasparini Effectively Mixing Two Fluids at If only the simulations

Comment on Planck Temperature Video

The Planck Temperature – Absolute Hot: What is the hottest temperature possible 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”

Facebook has no “share” or “tweet”

Lisa Sykes Wallace There seems to be no way to Tweet (share posts with link and short note) on Facebook that I can see. But I found Pichurro’s Mexican Grill on Facebook at Maybe you can post your picture on their Facebook page and write a short story to share with others who go

Twitter to @InnovationPhysics @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.

Comment on MegaAmpere to MegaGauss- Using laser fluctuations to measure gravitational potential turbulence

‪This intro added 10 Jul 2022 in update to “Solar System Gravimetry and Gravitational Engineering ” Comment on “MegaAmpere to MegaGauss” – Using laser fluctuations to measure gravitational potential turbulence To generate intense fields to control the motion of matter. To emulate gravitational acceleration so precisely there is almost no error in position or other

Note on my Facebook page about gravitational energy density

For more than 50 years I have been trying to understand the gravitational potential. I used it for orbit determinations when I worked at my first job at the CIA, then later worked on a NASA project to determine the geopotential itself using satellite orbits and measurements to solve for the shape and properties of
