Importance of EE/CE to Society
 2003 Northeast Power Failure
    People couldn’t get home – no subway
    No water in many bathroom sinks – electronic sensors
    No sales – electronic cash registers
    No entry for hotel guests – electronic keys
    Built-in answering machines didn’t work (press 1 for…)
    Some cell phones didn’t work
    Traffic lights didn’t work – commutes longer
    Gas pumps didn’t work – walk home
    Throw food away – refrigerators didn’t work
    Sleep outside – no A/C
    No money – ATMs and credit cards didn’t work
 Virtual Shutdown of normal life!!!!
