Modern Methods in Horology

by Grant Hood

Purchase through Amazon

This book offers a history of horology to the turn of the 20th century, with chapters on watchmaking and repair. Perhaps author Grant Hood can put the aims of the book in the best perspective:

“Knowing the difficulties that present themselves to the average watchmaker as he begins serving his apprenticeship and knowing how limited the supply of knowledge he is able to find and understand I have been prompted to write these pages, hoping the information may be such that it will encourage those that are discouraged, add renewed vigor to those who are ambitious and act as a warning to the ones that are inclined to be careless with their work. My aim will be to make each subject as simple and clear as possible, adding illustrations in all cases where they are needed. If the book is successful in helping my brother workmen and shall bring to them some new ideas that shall be beneficial or shall be the means of enabling them to do their work in an easier manner, the writer will feel that his labor has not been in vain and will be well pleased.”

This new edition is dedicated to San Tun Oo, enthusiastic collector of watches.

Best Practices for High Impact Threats to Critical Infrastructure provides transcripts of the 2016 InfraGard National EMP SIG ™ (EMP SIG)™ sessions at the Dupont Summit and additional materials from the subsequent months. The conference also reviewed nationwide activities of the EMP SIG including the release of Powering Through. It is a planning guide for communities, companies, and government agencies to help prepare for and mitigate widespread prolonged infrastructure collapse.

The conference segments also reflect the work of EMP SIG members at the National Guard Bureau, the Society for Disaster Medicine and Public Health and the INCOSE Critical Infrastructure Protection and Recovery Working Group that provided key articles reprinted from the December 2016 INCOSE Journal Insight. The EMP Commission’s final letter to Congress and a Resilient Hospitals Handbook are also included.

InfraGard EMP SIG Publications:
Beginning December 2015, the EMP SIG developed a planning guide named Powering Through for organizations to use to enhance their own continuity of operations and disaster plans in light of the new National Space Weather Strategy and manmade EMP and cyber threats. Work is planned for 2016 for an expanded second edition. Copies can be ordered at: https://www.empcenter.org/publications/planning-guide/ This complements the Triple Threat Power Grid Exercise also published by Westphalia Press and Amazon.

Information on these planning materials and upcoming activities can also be acquired by contacting the EMP SIG at igempsig@infragardmembers.org. To join InfraGard and the EMP SIG, apply on the home page of InfraGard.org.

About the InfraGard National EMP SIG: The InfraGard National EMP SIG™ was formed in July 2011 for the purpose of sharing information about catastrophic threats to our nation’s critical infrastructure. The ultimate goal of the EMP SIG is to assist local communities to enhance their own resilience with a special emphasis on developing protected local infrastructure ranging from local power generation and energy storage to water and food production.

The Philosophical Society of Washington was founded on March 13, 1871. It was preceded by gatherings at the home of Joseph Henry, the great scientist whose discoveries laid foundations for advances in magnetism and electromagnetism. Since 1887 it has met at Cosmos Club, in whose founding Philosophical members played a large part. In 1878, when Cosmos was founded, it was feared that Philosophical would start an alternative club, so all present members of Philosophical Society were invited to join as founding members of Cosmos.
