John Francis – författare

When the struggle to save oil-soaked birds and restore blackened beaches left him feeling frustrated and helpless, John Francis decided to take a more fundamental and personal stand—he stopped using all forms of motorized transportation. Soon after embarking on this quest that would span two decades and two continents, the young man took a vow of silence that endured for 17 years.

The theory of topological modular forms is an intricate blend of classical algebraic modular forms and stable homotopy groups of spheres. The construction of this theory combines an algebro-geometric perspective on elliptic curves over finite fields with techniques from algebraic topology, particularly stable homotopy theory. It has applications to and connections with manifold topology, number theory, and string theory. This book provides a careful, accessible introduction to topological modular forms. After a brief history and an extended overview of the subject, the book proper commences with an exposition of classical aspects of elliptic cohomology, including background material on elliptic curves and modular forms, a description of the moduli stack of elliptic curves, an explanation of the exact functor theorem for constructing cohomology theories, and an exploration of sheaves in stable homotopy theory. There follows a treatment of more specialized topics, including localization of spectra, the deformation theory of formal groups, and Goerss--Hopkins obstruction theory for multiplicative structures on spectra. The book then proceeds to more advanced material, including discussions of the string orientation, the sheaf of spectra on the moduli stack of elliptic curves, the homotopy of topological modular forms, and an extensive account of the construction of the spectrum of topological modular forms. The book concludes with the three original, pioneering and enormously influential manuscripts on the subject, by Hopkins, Miller, and Mahowald.

This book explores the process of rebuilding the Conservative Party under David Cameron's leadership since 2005. It traces the different elements of the renewal strategy - ideological reconstruction policy reappraisal and enhanced electoral appeal - and identifies constraints from different sections of the Party, including the parliamentary party and the grassroots membership. It also explores the extent to which long-standing intra-party divisions exacerbated difficulties for the exercise of leadership. The process of renewal has been through a number of stages and its progress has been indirect rather than linear. Although the project has been relatively successful in some respects the extent to which it has created a new Conservative Party remains contested. This book provides essential background and analysis, and will be of interest to students and scholars of British politics and government.

Join the Planetwalker, John Francis, on an exploration of kindness, great and small. From the kindness John has experienced in his own life to the history of how kindness has helped to shape our laws, morals and communities, read many inspirational stories from around the world.Over the whole history of humankind, kindness has been key to the survival of our species and to making our world a better place. Learn about Harriet Tubman, who risked her life to help others escape from slavery, the Nomads Clinic, which sends doctors trekking into the Himalayas to tend to patients, The Linda Lindas, a group of young musicians who use their talent to speak up for the rights of others Joshua Coombes, a hairdresser who gives free haircuts to the homeless, and many others. The joyous and awe-inspiring stories in this book will encourage young readers to be kind to others. And being kind, even in small ways, turns out to be healthy for you, yet another reason to be practise kindness every day. It’s our planet to share together – let's be kind.
