IN 2015, an observatory high in the Atacama Desert of Chile detected three planets orbiting an M star, an ultra-cool dwarf, in the constellation Aquarius about 40 light years, or 232 trillion miles, from Earth. Until then, the dim star was designated 2MASS J23062928-0502285. Not such a charming name. The discoverers of its satellites, a team of astronomers who operate the Chilean observatory remotely from Liege in Belgium, took the opportunity to warm up that appellation.
The 50th anniversary of the Free Speech Movement this year is also the 50th anniversary of the Wilderness Act. In the turbulent river of radicalism that reached flood stage in mid-’60s Berkeley, radical environmentalism was just one branch. That is the tributary I want to navigate here. But it is good to sit down at the typewriter—excuse me, the computer—and try to remember that frenzied era in a disciplined way. Ah, the piquancy of the air back then! The smell of tear gas on campus! There were so many flavors of radicalism available that one was forced to focus.
