3D printing can be used to automate the manufacturing of building elements for large-scale structures such as skyscrapers, aircraft, rockets and space bases without human intervention. However, challenges in materials, processes, printers and software control must first be overcome for large-scale 3D...

From extremely large systems like rockets1 to ultra-small nanophotonic devices2, numerical simulations provide scientists and engineers with the necessary tools to design nonintuitive structures. In electromagnetics, direct solvers, including the finite difference time domain (FDTD)3 and the finite ...

So yes, fiction is more predictable than nonfiction across the sweep of a whole narrative (because the beginnings and ends of novels are rhetorically very distinct). But the same observation doesn’t necessarily hold as we move from page to page, or sentence to sentence. At that scale, ficti...
