It began one quiet autumn evening during November of 1996. At home, David Head was viewing the PBS documentary Transportation in America and he noticed the film made no mention of African American contributions. But as chairman of the Black History Committee for Transport Workers Union Local 100, he knew there was much to share. At that moment Head determined his new purpose in life would be to share the extraordinary life and legacy of Granville T. Woods.After twelve years in pursuit of this goal, David Head has accomplished a great deal for his cause: - Metropolitan Transportation Authority Sponsorship of 2004 Subway Centennial Granville T. Woods Commemorative Exhibit - 4 million Granville T. Woods Commemorative Metro Cards (2 million in Spanish) - 2009: Brooklyn Street renamed "Granville T. Woods Way" - 2009: Figure 8, the world's first electric roller coaster created by Woods was inducted into the Coney Island Hall of Fame - 2010: Transit News Telly Award for GTW documentary - 2012: Granville T. Woods: African American Communication and Transportation Pioneer, an illustrated book for young readers, highlighting Woods' struggles and achievements, was published With his many successes, and realizing the impact he could have on others, Head decided to pursue his goals within an educational framework as well by: - Showcasing Woods' inspirational life and amazing innovative abilities - Revealing the purpose behind teaching the life and accomplishments of Woods, and his significant contributions to our American Society - Encouraging youth to cultivate their own talents, to stay in school and seek higher education, to discern their abilities and pursue them as Woods didIn the spirit of Granville T. Woods and his life of invention, Head is now spearheading a major effort to increase the participation of urban youth in the fields of science and technology. By integrating field trips and practical experience with his S.T.E.M. program classroom curriculum, youth will be motivated and guided in an innovative approach to comtemporary challenges. With this goal in mind, careers in science and technology will be encouraged and given direction.

Carefully coordinated, reliable, and accurate time synchronization is vital to a wide spectrum of fields—from air and ground traffic control, to buying and selling goods and services, to TV network programming. Ill-gotten time could even lead to the unimaginable and cause DNS caches to expire, leaving the entire Internet to implode on the root servers.Written by the original developer of the Network Time Protocol (NTP), Computer Network Time Synchronization: The Network Time Protocol on Earth and in Space, Second Edition addresses the technological infrastructure of time dissemination, distribution, and synchronization—specifically the architecture, protocols, and algorithms of the NTP. This system has been active in one form or another for almost three decades on the Internet and numerous private networks on the nether side of firewalls. Just about everything today that can be connected to a network wire has support for NTP.This book: Describes the principal components of an NTP client and how it works with redundant servers and diverse network paths Provides an in-depth description of cryptographic and other critical algorithms Presents an overview of the engineering principles guiding network configurationEvaluating historic events that have taken place since computer network timekeeping started almost three decades ago, the author details a number of systems and drivers for current radio, satellites, and telephone modem dissemination and explains how we reckon the time, according to the stars and atoms. The original 16 chapters of the first edition have been rewritten, updated, and enhanced with new material. Four new chapters cover new algorithms and previously uncovered concepts, including timekeeping in space missions.Praise for the first edition:"… For those that need an exhaustive tome on all of the minutiae related to NTP and synchronization, this is the source. … definitive … this book should be considered the last word on the topic."—Ben Rothke on Slashdot.org"… the bible of the subject… contains enough information to take you just as far as you want to go….Dr. Mills is the original developer of NTP."—Books On-Line
