Journey Through Time
Time in Everyday Life
Time in Everyday Life • Location and Positioning
– Radar, SatNav
• Timing in:
– Telecoms, Mobile Phones
– Power
– Financial Transactions
– Broadcasting

Scientist or Engineer? “The only reason for time is so that everything doesn't happen at once”
“The only way of discovering the limits of the possible is to venture a little way past them into the impossible”
“Engineers deliver Scientists’ bright ideas”
