Hot & Cold Electricity
As I kid, I used to help my dad with electrical wiring projects (among other things). I learned that home electricity was “hot & cold”, like water in pipes — or at least, that’s how I understood the explanation. Later …… Continue reading

Hamiltonian Flow
Newton wrote, “My brain never hurt more than in my studies of the moon [and Earth and Sun]”. Unsurprising sentiment, as the seemingly simple three-body problem is intrinsically intractable and practically unpredictable. … If chaos is … Continue reading

Losing Betelgeuse
At my computer Tuesday evening, I receive a message from a university physics chat that is both thrilling and chilling: LIGO and Virgo report a “burst” gravitational wave event, possibly due to a core-collapse supernova (or a binary collisi… Continue reading

Intrepid-Surveyor
Fifty years ago, Apollo 12 landed within sight of another spacecraft, a dramatic demonstration of pinpoint landing capability. While Dick Gordon orbited Luna in the command module Yankee Clipper, Pete Conrad and Al Bean left the lunar module Intrepid a… Continue reading
