Edison vs. Tesla; The Battle Over Their Last Invention

$9.99
More Info
Thomas Edison closely following the alternative physics work of Albert Einstein and Max Planck, convincing him that there was an entire reality unseen by the human eye. This led to the last and least-known of all Edison's inventions, the spirit phone. His former associate, now bitter rival, Nikola Tesla, was also developing at the same time a similar mysterious device. Edison vs. Tesla examines their quest to talk to the dead. It reveals:

Edison's little-known near-death experience formed his theory that animate life forms don't die, but rather change the nature of their composition. It is this foundational belief that drove him to proceed with the spirit phone.
Tesla monitored Edison's paranormal work, with both men racing to create a device that picked up the frequencies of discarnate spirits, what today is called EVP (Electronic Voice Phenomenon).
Both men were way ahead of their time, delving into artificial intelligence and robotics.
Although mystery and lore surround the details of the last decade of Edison's life, many skeptics have denied the existence of the mysterious spirit phone. The authors have researched both Edison's and Tesla's journals, as well as contemporary articles and interviews with the inventors to confirm that tests were actually done with this device. They also have the full cooperation of the Charles Edison fund, affording them access to rare photos and graphics to support their text. Edison vs. Tesla sheds light on this weird invention and demonstrates the rivalry that drove both men to new discoveries.

"As a contribution to the history of mathematics, this is a model of its kind. While adhering to the basic outlook of Eisenstein and Kronecker, it provides new insight into their work in the light of subsequent developments, right up to the present day. As one would expect from this author, it also contains some pertinent comments looking into the future. It is not however just a chapter in the history of our subject, but a wide-ranging survey of one of the most active branches of mathematics at the present time. The book has its own very individual flavour, reflecting a sort of combined Eisenstein-Kronecker-Weil personality. Based essentially on Eisenstein's approach to elliptic functions via infinite series over lattices in the complex plane, it stretches back to the very beginnings on the one hand and reaches forward to some of the most recent research work on the other. (...) The persistent reader will be richly rewarded."
A. Frohlich, Bulletin of the London Mathematical Society, 1978"

Instant #1 New York Times bestseller! - #1 Washington Post bestseller! - #1 Indie Bestseller! - USA Today Bestseller!

John Green, acclaimed author and passionate advocate for global healthcare reform, tells a deeply human story illuminating the fight against the world's deadliest infectious disease. Signed edition

"The real magic of Green's writing is the deeply considerate, human touch that goes into every word." -The Associated Press

"Told with the intelligence, wit, and tragedy that have become hallmarks of the author's work.... This is the story of us." -Slate

"Earnest and empathetic." -The New York Times

Tuberculosis has been entwined with hu­manity for millennia. Once romanticized as a malady of poets, today tuberculosis is seen as a disease of poverty that walks the trails of injustice and inequity we blazed for it.

In 2019, author John Green met Henry Reider, a young tuberculosis patient at Lakka Government Hospital in Sierra Leone. John be­came fast friends with Henry, a boy with spindly legs and a big, goofy smile. In the years since that first visit to Lakka, Green has become a vocal advocate for increased access to treatment and wider awareness of the healthcare inequi­ties that allow this curable, preventable infec­tious disease to also be the deadliest, killing over a million people every year.

In Everything Is Tuberculosis, John tells Henry's story, woven through with the scientific and social histories of how tuberculosis has shaped our world--and how our choices will shape the future of tuberculosis.
