#4718 Liquid-Based Gold Dust Filter This Machine Separated Fine Gold From Black Sand in 2 Minutes | Goldbay https://youtu.be/eVYCgNg2yHM #4718  What is it called when you have liquids of different densities in a container? When distinct liquids settle into separate layers based on their relative densities, the setup and physical phenomena are referred to by a few specific terms depending on the context: Density Column (or Density Tower ): The common name for the physical setup or demonstration where liquids with differing densities and low miscibility (e.g., honey, dish soap, water, vegetable oil) are stacked in a container. Density Stratification (or Liquid Stratification ): The formal physics and fluid dynamics term describing the layering effect itself, where gravitational forces arrange fluid layers with the densest at the bottom and the least dense at the top. Immiscible Phase Separation : The chemical term used when the liquids cannot dissolve into one another (such as oil ...

#4717 Smallest Theoretical Volume for Self-Sustaining Fusion Reaction

#4717 Smallest Theoretical Volume for Self-Sustaining Fusion Reaction #4717  Theoretically, what is the smallest volume for a self-sustaining fusion reaction (assuming fuel is added as needed)? A continuous, self-sustaining (ignited) fusion reaction requires that the heating power from charged fusion products—principally the 3.5 MeV alpha -particles in a Deuterium-Tritium (D-T) reaction—exceeds all energy loss channels (radiation and transport) without relying on external input power. Because theoretical minimum volume depends entirely on how the plasma is confined and how dense it is, the limits fall into three distinct physical regimes: Confinement Regime Typical Density (n) Confinement Time (τE​) Theoretical Minimum Volume Pulsed Inertial (ICF) sim 10^25 - 10^26 cm^-3 sim 10 - 100 ps sim 10^-6 cm^3  (sub-millimeter) Ultra-High Magnetic Field ( $B \sim 20\text{--}30\text{ T}$ ) sim 10^14 - 10^15 cm^-3 sim 0.5 - 2 s sim 10--50 m^3 Conventional Magnetic (Tokamak/Stellarator)...

#4716 U.S. Rodeo Circuits #4716  Tell me about the various Rodeo circuits in the U.S. In professional American rodeo, the circuit system was established in 1975 by the Professional Rodeo Cowboys Association (PRCA) to allow competitors to compete regionally without having to travel across the entire country year-round. Alongside the PRCA, several major associations and independent circuits shape the national competitive landscape. PRCA Regional Circuits The PRCA and the Women's Professional Rodeo Association (WPRA) divide the United States into 12 regional circuits (plus international extensions like the Maple Leaf Circuit in Canada): Circuit Covered States / Region Notable Premier Events Texas Texas Fort Worth, San Antonio, Houston, Austin Columbia River Washington, Oregon, Northern Idaho Pendleton Round-Up, Puyallup, Ellensburg California California California Rodeo Salinas, Red Bluff, Clovis Wilderness Utah, Nevada, Southern/Central Idaho Reno Rodeo, Snake River Stampede, O...
