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

Gauthier Östervall The mechanisms by which energy moves in solids, liquids, gas, mixtures solutions, structures all depend on the details of what you are doing. I am reviewing “shock vaporization” and “shock melting” this morning. It mainly affects meteor impact melting and vaporization but also hypervelocity flight, reentry, weapons development, explosive compression and forming, magnetic

Even with perfect knowledge of all things, and global optimized systems possible, would anyone change? No. If it fails, and is needed, it can be recreated in the future. Nothing on earth cannot be restored, if sufficient time, ability, determination and effort is applied. If China overproduces and they can survive, they likely will continue

USGS.gov can serve the whole world in all languages, part of a global knowledge network. I want to know how long and deep a fault area needs to be to generate a magnitude 9 earthquake. I know that the moment and power depend on the area, roughness, pressure, temperature, materials, and faults, depth and

Art Berman @aeberman12 Thriving luxury car manufacturers and struggling discount stores summarizes the current economic backdrop. The wealth divide is growing and the rich have never been richer than they are now. How is this “strong” economy? #economy #EconomyNews #EconomyMonetary #inflation https://pic.x.com/ywzoiakygl x.com/KobeissiLetter… Now, one can optimize global $1E12 industries more easily than selling 1E12 things for $1

Zhigang Suo @zhigangsuo Jun 11 A beginning thermodynamics course is preoccupied with a fluid, modeled as a system of two independent variables. The number “two” is a choice of convenience, not a matter of principle. Here is a system of one independent variable. https://pic.x.com/0jobgnimo5 Replying to @zhigangsuo Kilo, Mega, Giga, Tera, Peta, milli, micro, nano, pico, femto,

If a conductor is connected to a voltage source it will charge to the capacity of the conductor. If two conductors are charged, will there be a force between them? Two places of a capacitor are conductors, there is a force between them when there is voltage applied to the conductors. Can you explain and

https://www.facebook.com/reel/982103566933564 You can make a holder and cutter with cameras and controls to cut smaller and smaller. What tools you use determine how small, but better than using eyes, hands and cutters that are really rather large and blunt. Perhaps laser(s). Your videos are often intriguing, but I am almost always dissatisfied because it is

https://www.facebook.com/reel/982103566933564 Facebook – Memory storage devices. Other possibilities, and the future I used every one of those in many places. But before those were vacuum tube memories, relay memories, magnetic cores, bubble memories, washing machine sized disk drives, paper tape, magnetic wires, and many others. My first computer I made out of straight pins and
