This Is Not Yet A Scientific Age.

As You Know, A Theory In Physics Is Not Useful Unless It Is Able To Predict Underlined Effects Which We Would Otherwise Expect.

Unless A Thing Can Be Defined By Measurement, It Has No Place In A Theory. And Since An Accurate Value Of The Momentum Of A Localized Particle Cannot Be Defined By Measurement It Therefore Has No Place In The Theory.

I Would Rather Have Questions That Can't Be Answered Than Answers That Can't Be Questioned.

The Most Important Thing I Found Out From My Father Is That If You Asked Any Question And Pursued It Deeply Enough, Then At The End There Was A Glorious Discovery Of A General And Beautiful Kind.

The Game I Play Is A Very Interesting One. It's Imagination In A Straightjacket, Which Is This: That It Has To Agree With The Known Laws Of Physics. ... It Requires Imagination To Think Of What's Possible, And Then It Requires An Analysis Back, Checking To See Whether It Fits, Whether Its Allowed, According To What's Known, Okay?
