main contribution
proposed the crystal diffraction relationship, developed X-ray crystal structure analysis with his father, and won the 1915 Nobel Prize in Physics.
Biographical or institutional source material ↗’s relevance in technology cases
The following cases cite their theories, methods or industry contributions; the historical basis does not mean that I directly participated in or invented modern products alone.
Bruker D8 ADVANCE X-ray diffractometer Interdisciplinary principle illustration of ↗
Bragg condition connects the diffraction angle and interplanar spacing; the peak width is also affected by the grain size, microstrain and instrument broadening, and quantitative explanation requires calibration and appropriate models.

electrons enables high spatial resolution, but lens aberration, sample thickness, beam damage, and contrast transfer collectively limit the interpretable information.
