Thank You Very Much, I Enjoyed Myself

To Do Any Important Work In Physics A Very Good Mathematical Ability And Aptitude Are Required. Some Work In Applications Can Be Done Without This, But It Will Not Be Very Inspired. If You Must Satisfy Your "personal Curiosity Concerning The Mysteries Of Nature" What Will Happen If These Mysteries Turn Out To Be Laws Expressed In Mathematical Terms (as They Do Turn Out To Be)? You Cannot Understand The Physical World In Any Deep Or Satisfying Way Without Using Mathematical Reasoning With Facility.

It Appears That There Are Enormous Differences Of Opinion As To The Probability Of A Failure With Loss Of Vehicle And Of Human Life. The Estimates Range From Roughly 1 In 100 To 1 In 100,000. The Higher Figures Come From The Working Engineers, And The Very Low Figures From Management.

I, A Universe Of Atoms, An Atom In The Universe.

It Requires A Much Higher Degree Of Imagination To Understand The Electromagnetic Field Than To Understand Invisible Angels. ... I Speak Of The E And B Fields And Wave My Arms And You May Imagine That I Can See Them ... [but] I Cannot Really Make A Picture That Is Even Nearly Like The True Waves.
