"For in 1900 all electromagnetic radiation of longer wavelengths was already known at least to the extent that one could not seek in it the more striking characteristics of X-rays such as, for example, the strong penetrating power"
About this Quote
The explicit point is narrow - don’t expect X-ray style penetration from longer-wave radiation. The subtext is broader and sharper: discovery doesn’t just depend on instruments, it depends on what a community considers worth looking for. Laue implies that by 1900 the scientific gaze had been trained to associate novelty with shorter wavelengths and higher energies, because X-rays had recently arrived as a kind of glamorous anomaly. “Strong penetrating power” isn’t merely a property; it’s a cultural marker of excitement, a feature that made X-rays feel like a rupture rather than an incremental extension.
Context matters here because Laue’s own legacy is tied to a different rupture: X-ray diffraction and the birth of modern crystallography. Read backward, the quote feels like an explanation for why certain questions weren’t asked until they suddenly were. It’s a reminder that the frontier of knowledge is policed not only by what we don’t know, but by what we think we already know well enough to stop being curious about.
