characterize optical coherence tomography (OCT) 3D resolution by imaging point spread function of sub-resolution particles. captured PSF is used as feedback to calibrate OCT systems for an optimal shape of the PSF to improve system resolution.

a satisfying experiment when journeying reduce: sending operation to alter sequence, using the reduce contract. (defn seq-op [s op] (conj s (op s))) (defn fib-op [s](+ (first s) (second s))) (reduce seq-op '(1 1) (repeat 5 fib-op)); (13 8 5 3 2 1 1)

Today's Python history lesson: Python took its control and data structures from ABC, its identifiers, strings and %-string formats from C, and its regular expressions from Perl. But its # comments (and #!) and -c command line flag came from the UNIX v7 shell.

Weird: - Make a one-dimensional "crystal" where each site contains an atom if the corresponding number is prime. - Simulate x-ray diffraction going through it. - Out comes a... quantamagazine.org/a-chemist-shin…
