Who Will Observe The Observers?

We Have Found That Where Science Has Progressed The Farthest, The Mind Has But Regained From Nature That Which The Mind Has Put Into Nature. We Have Found A Strange Foot-print On The Shores Of The Unknown. We Have Devised Profound Theories, One After Another, To Account For Its Origin. At Last, We Have Succeeded In Reconstructing The Creature That Made The Foot-print. And Lo! It Is Our Own.

The Understanding Between A Non-technical Writer And His Reader Is That He Shall Talk More Or Less Like A Human Being And Not Like An Act Of Parliament. I Take It That The Aim Of Such Books Must Be To Convey Exact Thought In Inexact Language... He Can Never Succeed Without The Co-operation Of The Reader.

But It Is Necessary To Insist More Strongly Than Usual That What I Am Putting Before You Is A Model-the Bohr Model Atom-because Later I Shall Take You To A Profounder Level Of Representation In Which The Electron Instead Of Being Confined To A Particular Locality Is Distributed In A Sort Of Probability Haze All Over The Atom.

To The Pure Geometer The Radius Of Curvature Is An Incidental Characteristic - Like The Grin Of The Cheshire Cat. To The Physicist It Is An Indispensable Characteristic. It Would Be Going Too Far To Say That To The Physicist The Cat Is Merely Incidental To The Grin. Physics Is Concerned With Interrelatedness Such As The Interrelatedness Of Cats And Grins. In This Case The "cat Without A Grin" And The "grin Without A Cat" Are Equally Set Aside As Purely Mathematical Phantasies.

It Cannot Be Denied That For A Society Which Has To Create Scarcity To Save Its Members From Starvation, To Whom Abundance Spells Disaster, And To Whom Unlimited Energy Means Unlimited Power For War And Destruction, There Is An Ominous Cloud In The Distance Though At Present It Be No Bigger Than A Man's Hand.
