“Physics for FUTURE LEADERS”

Prof. Paul Steinhardt

PLEASE NEVER SIT IN THE LAST 8 ROWS

Welcome to Physics 115

“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• Our “natural” intuition is outdated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
