The sticking point is that, unlike forgiving chicken legs and roots, which have a relatively wide window of doneness, shrimp and zucchini can be finicky.

The particle accelerators that enable high-energy physics and serve many fields of science, such as materials, medical, and fusion research, are driven by superconducting magnets that are, to put it simply, quite finicky.
