Of the three most eminent US physicists of the late nineteenth century, Gibbs, Michelson and Rowland, it was the “doughty knight of Baltimore” who had the broadest impact, setting the pace for the golden age of US physics.
“Those were the days,” reminisced Daniel Gilman, the President of The Johns Hopkins University, “when scientific lecture‐rooms in America gloried in demonstrations of ‘wonders’ of Nature—‘the bright light, the loud noise, and the bad smell.’ Rowland would have none of this.” The Johns Hopkins physicist thus characterized was Henry Rowland, whose contributions—particularly those in spectroscopy and electromagnetism—secured him a high place in the ranks of nineteenth‐century physicists.

An interview with a prominent member of the Marshallese diaspora delves into the ongoing impact of aboveground US nuclear weapons testing in the Pacific archipelago.
Detecting quantum particles of gravity was long considered hopeless. A new perspective, which takes advantage of quantum technologies, suggests that an experimental realization may be closer than previously thought.
