“Physics for FUTURE LEADERS”
If you are going to be a leader in the real world, you have to know how the real world works
• Our “natural” intuition is outdated

“Physics for FUTURE LEADERS”• Our modern “experience” thru TV, movies,
YouTube, etc. is misleading
-- a bullet sends a victim flying out the windowbut the shooter remains motionless
-- laser beams can be seen traveling thru space
-- spaceships maneuver like airplanes
-- submarines explode
