‘Lone’ longitude genius may have had help
The story of John Harrison the “lone genius” who solved the problem of finding longitude at sea is in urgent need of a rewrite.
Discoveries made during repairs to Harrison’s first successful “sea clock” – completed in 1735 – suggest that others contributed to his pioneering timepieces. “Harrison is always [...]

Landmarks: Birth of Modern Electronics
In June 1948, the Physical Review published a description of a novel electronic device that “may be employed as an amplifier, oscillator, and for other purposes for which vacuum tubes are ordinarily used.” That statement hardly begins to capture the importance of the transistor, which made possible technology unimaginable at the [...]

Who Watches the Watchman?
Let’s say you own a big building full of valuable stuff. How do you make sure that the night watchman patrolling your factory floor or museum galleries after closing time actually makes his rounds? How do you know he’s inspecting every hallway, floor, and stairwell in the facility? How do you know [...]

Skulls in the Stars: Mr. Faraday goes wild — with atomic speculation! (1844)
There’s discussion of hard impenetrable spheres, but no, it’s not a “spring break” exposé. Just good old physics.
