What Is Especially Striking And Remarkable Is That In Fundamental Physics, A Beautiful Or Elegant Theory Is More Likely To Be Right Than A Theory That Is Inelegant. A Theory Appears To Be Beautiful Or Elegant (or Simple, If You Prefer) When It Can Be Expressed Concisely In Terms Of Mathematics We Already Have. Symmetry Exhibits The Simplicity. The Foundamental Law Is Such That The Different Skins Of The Onion Resemble One Another And Therefore The Math For One Skin Allows You To Express Beautifully And Simply The Phenomenon Of The Next Skin.

Enthusiasm Is Followed By Disappointment And Even Depression, And Then By Renewed Enthusiasm.

I Thought Of Killing Myself But Soon Decided That I Could Always Try Mit And Then Kill Myself Later If It Was That Bad But That I Couldn't Commit Suicide And Then Try Mit Afterwards. The Two Operations, Suicide And Going To Mit, Don't Commute.
