Tunable, phase-locked hard X-ray pulse sequences generated by a free-electron laser
The ability to arbitrarily dial in amplitudes and phases enables the fundamental quantum state operations pioneered for microwaves and then infrared and visible wavelengths during the second half of the last century. Self-seeded X-ray free-electron lasers (FELs) routinely generate coherent, high-brightness, and ultrafast pulses for a wide range of experiments, but have so far not achieved a comparable level of amplitude and phase control. Here we report the first tunable phase-locked, ultra-fas…

Calamus 44 Here my last words
In which the poet outs himself through talking about his poetry.
It's a short piece of Whitman talking about his own writing. But he's so twisted up!
Here I shade down and hide my thoughts—I do not expose them,
And yet they expose me more than all my other poems.
I read this as him talking about Calamus, the cluster of gay poems. And directly telling us that he's censored and hidden what he really wants to say. And yet still these poems still expose his true self. It makes me feel sad for Whitman, imagine his writing if he felt less fettered.
Still, he published some of the most clear gay poems of the 19th century. And got famous and mainstream doing it.
