This classic by one of the twentieth century's most prominent mathematicians offers a concise introduction to set theory. Suitable for advanced undergraduates and graduate students in mathematics, it employs the language and notation of informal mathematics. There are very few displayed theorems; most of the facts are stated in simple terms, followed by a sketch of the proof. Only a few exercises are designated as such since the book itself is an ongoing series of exercises with hints. The treatment covers the basic concepts of set theory, cardinal numbers, transfinite methods, and a good deal more in 25 brief chapters."This book is a very specialized but broadly useful introduction to set theory. It is aimed at 'the beginning student of advanced mathematics' ... who wants to understand the set-theoretic underpinnings of the mathematics he already knows or will learn soon. It is also useful to the professional mathematician who knew these underpinnings at one time but has now forgotten exactly how they go. ... A good reference for how set theory is used in other parts of mathematics." -- Allen Stenger, The Mathematical Association of America, September 2011.

Nice Wallet
Beautiful men’s leather wallet by Fossil. Came in a tin gift box. Nice and big, which is what I was looking for. Has a pocket for coins. Planning on giving it to husband for Father’s Day and I know he’s gonna love it.

Fits your COVID vaccine card!
This wallet is very lovely (fine workmanship, smooth and not distressed leather as in the photo). Comes in a quality metal box that has possibly thrilled my husband even more than the wallet itself. Holds everything including weird currencies, parking stubs, even your COVID vaccine document — you do have one, right?
Perfect gift.

Well made,
The leather is flawless, all the stitching is well done, the ability to organize my cards in groups worked out well.
It's overall size is fine, fits well in a front pocket, flatter than a tri-fold, not bulky.
My only wish would be making the width of the inner double sided leather card holder page pockets just 1/8" wider. In my opinion this would then be a 5-star wallet. One spot to hold some of the just wider than credit card size for easy access would be nice.
Besides that, I intend to use it until it is worn out. Nice wallet!
