What We Are Reading Today: Magnetic Reconnection

Author: Masaaki Yamada

Plasmas comprise more than 99 percent of the visible universe; and, wherever plasmas are, magnetic reconnection occurs.
In this common yet incompletely understood physical process, oppositely directed magnetic fields in a plasma meet, break, and then reconnect, converting the huge amounts of energy stored in magnetic fields into kinetic and thermal energy. In Magnetic Reconnection, Masaaki Yamada offers an illuminating synthesis of modern research and advances on this important topic.
Magnetic reconnection produces such phenomena as solar flares and the northern lights, and occurs in nuclear fusion devices.
A better understanding of this crucial cosmic activity is essential to comprehending the universe and varied technological applications, such as satellite communications.

Flowering currant, ivy, Portuguese laurel, and woad might all have grown in a medieval garden, but it would have taken special expertise to extract and create rich blue and purple pigments from them. 

Humans have been extracting dyes and inks from natural materials for millennia, and the practice was firmly established during the medieval era, recorded in manuscripts that survive today.

“Gold from Newton’s Apple Tree” brings together recipes for making natural colors according to season, method, and ingredients.
