Prepare to learn everything we still don't know about our strange and mysterious universe.Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore --there are huge yawning voids in our basic notions of how the world works. PHD Comics creator Jorge Cham and particle physicist Daniel Whiteson have teamed up to explore everything we don't know about the universe: the enormous holes in our knowledge of the cosmos. Armed with their popular infographics, cartoons, and unusually entertaining and lucid explanations of science, they give us the best answers currently available for a lot of questions that are still perplexing scientists, including: * Why does the universe have a speed limit?
* Why aren't we all made of antimatter?
* What (or who) is attacking Earth with tiny, superfast particles?
* What is dark matter, and why does it keep ignoring us? It turns out the universe is full of weird things that don't make any sense. But Cham and Whiteson make a compelling case that the questions we can't answer are as interesting as the ones we can. This fully illustrated introduction to the biggest mysteries in physics also helpfully demystifies many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humor and delight, Cham and Whiteson invite us to see the universe as a possibly boundless expanse of uncharted territory that's still ours to explore.

Sleek and mostly simple assembly and use
Size: 7.5 Inches - 2 Packs
I put the parts through the wash to sterilize them before using them. I think this introduced moisture into the grinding unit, which initially affected the grinding so that both the pepper and salt were coming out 'chunky'. I disassembled them and let them thoroughly dry. They are working great now after using them a few times.

A Perfect Gift For Someone Who is Tough To Buy For
Size: 5.3 Inches - 2 Packs with Holder
Very attractive looks and quality build. Most importantly the salt grinder will take sea salt down to powder for popcorn (a make-or-break feature in my house). It doesn't take up much room in the cabinet when stored and very easy to fill. We're just delighted with the value for the money. Any time you are stuck with what to get someone for a birthday, xmas, what ever; you can't go wrong with this Salt & Pepper Grinder Set.

It works but it's not high quality
Size: 5.3 Inches - 1 Pack
Grinder works well except the silver part came loose after using it a couple of times now we have to hold the top part really tight to use it probably should have returned it but it still works

Good Salt Grinder
Size: 5.3 Inches - 1 Pack
Bought this for the pink salt. It crushes it nicely and is easy to fill. The crushing didn't change the taste and this holds a considerable amount of sale. It's a great value for the money and would make a terrific gift.
