Having millions of consumers on the same grid smooths demand because aggregating many independent loads averages out individual ups and downs, reducing overall volatility.
When popular revolts succeed in middling dictatorships, regime change is often driven by elites because uprisings only prevail if the military or powerful courtiers withdraw support, and those elites then replace the ruler to protect their own positions rather than enact mass reforms.
Roman marine concrete grew stronger over centuries because seawater dissolves lime in the mix, which reacts with volcanic ash to precipitate interlocking aluminum‑silicate minerals (notably aluminum tobermorite) that fill pores and progressively densify and reinforce the material.
To stabilize rule after seizing power, a leader should minimize the number of required key supporters because fewer allies reduce how much scarce treasure must be distributed and simplify alliance management, lowering the chance a rival can flip enough to unseat them.
Grid operators dispatch generation by cost because using low‑cost, less‑flexible plants for steady base load and higher‑cost, flexible plants for peaks minimizes overall operating expense while meeting demand.
Potential supporters weigh expected survival and rewards before backing a coup because in stable democracies many already enjoy wealth and protections, and the risk of being purged after a seizure often outweighs uncertain gains.
