The Action Lab: What Happens if You Focus a 5W Laser With a Giant Magnifying Glass? Negative Kelvin Temperature! at https://www.youtube.com/watch?v=jdjTYlReE-I The intensity in Watts/meter^2 is roughly equal to the Stefan-Boltzmann constant times the 4th power of the temperature in Kelvin. When you focus parallel rays to a smaller area, the intensity goes up, and the

I am reading at https://www.opnme.com/opnMINER/document-data?ocDocId=5604694&repo=pmc. The background, text color and layout are difficult to read. Is there any way to turn off the background animation, set the font weight and size to readable values? I came across a note on ResearchGate asking for proposals. I was interested in your site and purpose. For the

Akira Kokado, You came up with an expression for the gravitational potential. Did you ever convert the earth’s geopotential into your form? [ My son and his small family live in Japan. He decided to go to college there and never came back to the USA. ] I worked with Steve Klosko on the early NASA

Colby Explanes: No One is Buying the Boeing 777-8, Here’s Why at https://www.youtube.com/watch?v=cjYfRmLaqpM A very useful summary. With closed designs, and tiny decision-making bodies, no open simulation models for economic, financial, social and technology impact, these kinds of $10 B to $10 Trillion errors will keep happening. I wonder what impact Elon Musk StarShip global point

ROSES 2021 Unit04: Distributed Acoustic Sensing with Dr. Eileen Martin at https://www.youtube.com/watch?v=psv1bgy5LUg You might want to edit this to remove the first few minutes where nothing is said. And put links in the description to Eileen’s work and group(s). This would be so much easier if you would just share your mathematics in symbolic mathematical form

Accelerometers and gradiometers get better at higher frequencies, use the Internet to multiply capabilities many fold https://www.researchgate.net/project/Solar-System-Gravimetry-and-Gravitational-Engineering These “updates” are just things I think are important to remember, and what I can find time and energy to write down. If you see something you disagree with, write me or make a comment. I got a

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.
