There are lonely, single skeins of yarn in every knitter’s closet — casualties of projects discarded in mid-row, single balls of luscious alpaca or cashmere that was too expensive to buy more than one, the leftovers from long-completed projects. Here are 101 original and charming solutions to the perpetual one-skein problem.

Wonders of Numbers: Adventures in Mathematics, Mind, and Meaning
Wonders of Numbers will enchant even the most left-brained of readers. Hosted by the quirky Dr. Googol--who resides on a remote island and occasionally collaborates with Clifford Pickover--Wonders of Numbers focuses on creativity and the delight of discovery. Here is a potpourri of common and unusual number theory problems of varying difficulty--each presented in brief chapters that convey to readers the essence of the problem rather than its extraneous history. Peppered throughout with illustrations that clarify the problems, Wonders of Numbers also includes fascinating "math gossip." How would we use numbers to communicate with aliens? Check out Chapter 30.
In every age, science and technology have played an important role in advancing human civilization. From architecture to engineering, communication to transportation, humans have invented and developed extraordinary wonders. Engineers take the discoveries of scientists and mathematicians to make practical things, from roads and bridges to weapons and vehicles. Electronic engineers design and build everything from television sets to computers. Chemical engineers research new uses for plastics and other materials. Other engineers design new energy sources and nonpolluting factories.
