Since the publication of Einstein's Special Theory of Relativity in 1905, the discovery of such astronomical phenomena as quasars, pulsars, and black holes -- all intimately connected to relativity -- has provoked a tremendous upsurge of interest in the subject.This volume, a revised version of Martin Gardner's earlier Relativity for the Million, brings this fascinating topic up to date. Witty, perceptive, and easily accessible to the general reader, it is one of the clearest and most entertaining introductions to relativity ever written.Mr. Gardner offers lucid explanations of not only the special and general theories of relativity, but of the Michelson-Morley experiment, gravity and spacetime, Mach's principle, the twin paradox, models of the universe, and other topics. A new Postscript, examining the latest developments in the field, and specially written for this edition, is also included.
The clarity of the text is especially enhanced by the brilliant graphics of Anthony Ravielli, making this "by far the best layman's account of this difficult subject." -- Christian Science Monitor.

Great construction but poor mounting hardware
They are great once your put them in but mounting them was a huge pain.
The included dry wall anchors are of really bad quality and rips up a huge opening if you have to undo them for whatever reason.
But the more infuriating thing is the screws they come with, which is not quite Philips 2 and easily slips from most standard driver bits. It is very easy to strip these if you are not careful. The small amount of space at the corner almost doesn't allow for easy drill access so you might have to get creative.
Overall good product, but I will highly recommend buying your own set of wall anchors and screws

Sturdy as heck But NOT easy to install
Because of the angles to install the screws, I'm definitely going to have to say NOT easy to install. Simple in concept; maybe if you have paper-thin walls. But if you don't it is a pain to screw those in with the tools provided. On the upside, they do come with a mini leveler. But it's just not a practical way of screwing in the shelf unless you are prepared to spend a surprising amount of time doing it. The shelves themselves are sturdy but that should be expected since it's basically a sheet of metal.

Perfect Nightstand Organizer and Looks Amazing
Color: Dark Brown
This valet tray is exactly what I was looking for. The wood looks great and feels sturdy, and it keeps all my everyday items in one place. I use it for my keys, wallet, watch, and phone, and my nightstand looks much neater now. Its great to keep all the thing you need when leaving the house in one place.
It’s the perfect size, well made, and looks nice enough to leave out on display. Would definitely recommend this if you want an easy way to keep your essential items organized or need a solid gift idea.
