In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it.

Perfectly Practical and Stylish!
Color: A-silver
This product does exactly what the description promises—and more! The silver metal caddy is not only sturdy and well-made, but it also keeps all of my items neatly organized and easily accessible. I love how sleek and modern it looks on my countertop. The design is thoughtful, with no water leaking from the bottom, and the slide-out tray collects any runoff, making it super easy to clean. It holds a surprising amount of items, including my dish soap dispenser, without feeling cluttered. For the price, this caddy offers fantastic value. I’m beyond happy with this purchase—it’s a game-changer for keeping my kitchen tidy!

Less mess, more style!
Color: Gold, Color: Gold
So happy with this purchase! I was a tiny bit wary buying an item without any reviews yet, however I saw that the other caddies from this brand all had many positive reviews and seemed to be good quality. The diatomaceous earth base of this caddy elevated this option to me, so I went for it. I've had it out for a few days and am extremely happy that I went with this option! It absorbs water super quickly, so there are no more rings and residue left on the top of my sink, and it makes my countertop look that much more cute and put-together. Heads up it is a little deep compared to some other trays/caddies; I knew this ahead of time so planned to put it directly to the side of my sink so that it did not overlap. I think the size is worth it, since it accommodates about 2 soap products and has plenty of adjustable room for bottle brushes, sponges, drain stoppers, and whatever other items you need. Overall, I highly recommend!

Sturdy and does the job well.
Color: Black
Very stable. Have a narrow ledge on my sink and it balances great without falling. Holds all my sponges and brushes and dish soap. Hasn’t rusted and I’ve had it for a while now. Looks nice on my sink. Keeps my counters dry and my sponges mold free.

Buy it you'll love it. You'll realize that you really needed it
Color: Black
Size is perfect for rag, scrubber sponges soap. It's very sturdy love that the block on bottom dryies up all the liquid it's absolutely amazing. It's very convenient, love the way you can organize everything. I'm the kind of person I have to have everything organized that's the way I grew up. I have not seen any signs of rust no where. Highly recommend. It is very very nice.

Funcional but smaller than I thought
Color: B-silver
I liked it and it replaces something around the kitchen sink that was constantly dripping liquid soap dish into the sink making a mess! This new organizes items much better. It's smaller than I envisioned and wish it came with it's own soap bottles dispensers but I found two small ones placing them side by side and it works. Did not use the metal divider. I cannot tell yet the drying speed of the sliding out stone. It's functional at keeping everything hands reach and organized around the kitchen sink.
