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.
What We Are Reading Today: Three Roads Back by Robert D. Richardson
In “Three Roads Back,” Robert Richardson, the author of magisterial biographies of Ralph Waldo Emerson, Henry David Thoreau, and William James, tells the connected stories of how these foundational American writers and thinkers dealt with personal tragedies early in their careers.
For Emerson, it was the death of his young wife and, 11 years later, his five-year-old son; for Thoreau, it was the death of his brother; and for James, it was the death of his beloved cousin Minnie Temple.
Filled with rich biographical detail and unforgettable passages from the journals and letters of Emerson, Thoreau, and James, these vivid and moving stories of loss and hard-fought resilience show how the writers’ responses to these deaths helped spur them on to their greatest work, influencing the birth and course of American literature and philosophy.
As Richardson shows, all three emerged from their grief with a new way of seeing, one shaped by a belief in what Emerson called “the deep remedial force that underlies all facts.”
