Nowadays folks know his Bolo works, but Dinosaur Beach, Worlds of the Imperium, End as a Hero, and the Retief series were pretty unique for their time. One of my favorite authors.

Dinosaur Beach has to be one of my favorite novels, its a cracking good time travel novel with transhumanism before such was known.

One Variety of Sea Slugs Cuts Out the Energy Middleman 232

There are several very cool results from String/M-theory, but nothing that can be fully understood without the mathematics. But a theory that fully explains all interactions, including matter fields, with supersymmetry and supergravity arising naturally from it, an explanation of the heirarchy problem, and use of perturbation theory and renormalization for gravitons which are generally non-renormalizable, is interesting.

Loop Quantum gravity is interesting too, especially for its background independence, but it will never explain matter fields, and the semiclassical sector is currently lacking. By contrast, string theory has a natural extension to classical general relativity.
