When a lightning return stroke heats a channel only centimetres wide to roughly 30,000 kelvin, about five times the temperature of the Sun’s visible surface, the air expands so violently that the pressure wave rolls across the ground as thunder Saving Tips July 28, 2026 A cloud-to-ground lightning return stroke can heat the air inside its narrow channel to roughly 30,000 kelvin, more than five…
In 1911, the Dutch physicist Heike Kamerlingh Onnes cooled a thread of mercury to 4.2 kelvin in a bath of liquid helium and its electrical resistance vanished completely, and a current set circulating in a superconducting loop like that will still be flowing years later, indistinguishable from the day it began Saving Tips July 24, 2026 Drop a small ring of superconducting metal into a bath of liquid helium, nudge a current through it, and remove…
