Looking At Something Changes It.

Nature Allows Only Experimental Situations To Occur Which Can Be Described Within The Framework Of The Formalism Of Quantum Mechanics

In General, Scientific Progress Calls For No More Than The Absorption And Elaboration Of New Ideas- And This Is A Call Most Scientists Are Happy To Heed.

Can Quantum Mechanics Represent The Fact That An Electron Finds Itself Approximately In A Given Place And That It Moves Approximately With A Given Velocity, And Can We Make These Approximations So Close That They Do Not Cause Experimental Difficulties?

I Think That The Discovery Of Antimatter Was Perhaps The Biggest Jump Of All The Big Jumps In Physics In Our Century.

I Would Much Prefer The Following Definition: An Expert Is Someone Who Knows Some Of The Worst Mistakes That Can Be Made In The Subject, And How To Avoid Them.
