Amateur Chemistry: Turning Dirt into Silicon at https://www.youtube.com/watch?v=Lo3O82dmPxA I really liked this because of the cleaning steps. I would not have done it those ways, but happy to watch your methods and hear your comments. I would likely have looked online to buy clean sand already powdered, and avoid time, acid, water and mess. The

Zhigang Suo @zhigangsuo The Nobel Laureate T.D. Lee died recently. @yangyang_cheng wrote about Lee’s role in lifting science in China, and in bridging China and America. These magical years of 1980s! https://npr.org/2024/09/05/nx-s1-5092630/td-lee-legacy-perspective-china-physics-yangyang-cheng Replying to @zhigangsuo and @yangyang_cheng Thanks for sharing! There have been many excellent and outstanding researchers from China working in China and around

Turtles all the Way Down: What is Dark Energy? at https://www.youtube.com/watch?v=S0lddIKoxYg My Comment: There are many processes, nuclear energy creation in stars foremost, that spread things out. Once gravitation and binding bring things together and nuclear fusion is possible, the nuclear energy created is much greater than gravitational energy. Our sun streams neutrinos, light, heat,

Ideal Weapon: Can Hafnium Bombs Replace Nuclear Bombs? at https://www.youtube.com/watch?v=FHPzQrJ8D7M Suggest you use NuDat3 at BNL to see all the isotopes that can be used. You also need all the magnetic moments, which I think they will be adding. Most of the radioactive isotopes can be used for their reactions. Not just stable ones if

Fly with Magnar: Why are so many pilots wrong about Bernoulli’s Principle? at https://www.youtube.com/watch?v=uyRx25MSWng @woodpile66 Most folks here seem to say that low pressure exists because the flow speeds up, but that group does not account for why the flow sped up in the first place, or the mandatory physics. I offer that the wing

Prof Van Buren: Intro to compressible flow [Aerodynamics #17] at https://www.youtube.com/watch?v=dDSgUTgcMXg Bad handwriting, use a computer. There are about 5.4 Billion people using the Internet now. Step up your presentations to match, not down to a hypothetical or organization driven “captive class room”. Your visualization are decent, but lack substantially because your drawing skills are

Fusion for SpaceX levitation, industrial and space needs. Global open tokens and global open resources I was reading https://en.wikipedia.org/wiki/Levitated_Dipole_Experiment today and encouraged. While the economics of bulk electricity production are not particularly favorable, there are many new transportation, industrial and space applications where GigaWatt and larger power modules are needed. For instance to

Chan Zuckerberg Initiative @ChanZuckerberg Imaging researcher @edithsandstroem + team captured this image in under 12 minutes—the same image generated with the current standard of mass spectrometers would take more than 3 days! https://pic.x.com/wu9fcipfnr Replying to @ChanZuckerberg and @edithsandstroem The electrospray Taylor cone approach for surface tension (surface energy) might well be applied to carbon, boron,

Zhigang Suo @zhigangsuo I had to look it up, but it makes perfect sense. It happens a lot on the Internet, where indirect connections between nodes, often outnumber direct ones. The connections and paths are by associates, supporters, advocates, funding agencies, stakeholders, alumni, founders, common interests. Most of these associations are real, but lost by
