    Cold Hot
AI Thread Summary
Understanding hot and cold is essential for advancements in high-temperature superconductivity and cold fusion. The extreme temperatures found in stars and the vacuum highlight the coexistence of hot and cold within discrete boundaries. Human survival is critically dependent on maintaining a narrow temperature range, illustrating the delicate balance of energy states. The discussion posits that temperatures cannot be simply added but can only be subtracted when systems combine, leading to concepts of kinetic and potential mass. The big bang singularity exemplifies this contradiction, being both pure kinetic and potential mass, which complicates its definition.

If scientists understand hot and cold completely then high temperature superconductivity will become a reality and cold fusion is just child play.

Until then, we can do all the theorizing we want but to really understand the universe we must understand what is hotness and what is coldness.

The interiors of the stars is extremely hot. The vacuum is extremely cold. And yet they coexist in such discrete boundary. While human beings can be kept alive at merely 98.6 degrees. A few degrees (+/-) deviation will cause almost instant death.

Pure coldness is 100% potential energy. Pure hotness is 100% kinetic energy. Most things are just in between.

If temperatures are used to represent hot and cold. Can the temperatures of two objects be added? Be subtracted? The truth is temperatures of two systems cannot be added but can be subtracted only when the system is combined into a new system.

Pure hotness can represents one kind of mass called kinetic mass. Pure coldness is another kind of mass called potential mass. So it can be said that the big bang singularity was made of pure kinetic mass because its temperature is infinite. But the singularity has no motion hence is also made of pure potential mass (temperature is zero from the kinetic theory of heat). It is this contradiction that makes the singularity undefinable.
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
