terrifying precision

Wait until this person gets a load of the Michelson-Morley experiment in the 1880s to measure the speed of light in all directions, opening the door for Einstein to formulate Special and General Relativity.

Let alone what they're doing now with entangled laser photons, beam-splitting crystals and mirrors that fluctuate in attoseconds.
Or what they're doing with non-entangled lasers and mirrors to detect gravitational waves in the very fabric of space-time, ripples one thousand times smaller than the width of a single proton.

Now that's terrifying precision right there. Although I'd prefer to use the term exquisite, I'd even go so far as calling it a miracle of science and engineering.
