A personal ode to the Boeing 747

The Boeing 747 flew its maiden voyage in early February of 1969, a week or so after I was born. This was not a commercial flight. That wouldn’t come until a year later, in late January of 1970, a week before my first birthday, when the world’s first jumbo jet took off from New York…

Engineers Create Stable Plasma Ring in Open Air | Caltech

For the first time, engineers at Caltech have created a stable ring of plasma in open air—essentially capturing lightning in a bottle, but without the bottle. Matter can exist in four distinct phases: solid, liquid, gas, and plasma. Plasmas are made of charged particles—ions and electrons—and occur naturally on Earth as lightning, in the weather…
