The Same Equations Have The Same Solutions

Every Instrument That Has Been Designed To Be Sensitive Enough To Detect Weak Light Has Always Ended Up Discovering That The Same Thing: Light Is Made Of Particles.

People Are Always Asking For The Latest Developments In The Unification Of This Theory With That Theory, And They Don't Give Us A Chance To Tell Them Anything About What We Know Pretty Well. They Always Want To Know The Things We Don't Know.

Therefore Psychologically We Must Keep All The Theories In Our Heads, And Every Theoretical Physicist Who Is Any Good Knows Six Or Seven Different Theoretical Representations For Exactly The Same Physics.

If All Of Mathematics Disappeared, Physics Would Be Set Back By Exactly One Week.

We Are At The Very Beginning Of Time For The Human Race. It Is Not Unreasonable That We Grapple With Problems. But There Are Tens Of Thousands Of Years In The Future. Our Responsibility Is To Do What We Can, Learn What We Can, Improve The Solutions, And Pass Them On.
