There Two Things That Are Infinite, Human

I Am Exclusively Occupied With The Problem Of Gravitation And Hope With The Help Of A Local Mathematician Friend [marcel Grossman] To Overcome All The Difficulties. One Thing Is Certain, However, That Never In Life Have I Been Quite So Tormented. A Great Respect For Mathematics Has Been Instilled Within Me, The Subtler Aspects Of Which, In My Stupidity, I Regarded Until Now As Pure Luxury.

I Do Not Believe In A Personal God And I Have Never Denied This But Have Expressed It Clearly.

It Is Always Delightful When A Great And Beautiful Idea Proves To Be Consonant With Reality.

...behind All The Discernible Laws And Connections, There Remains Something Subtle, Intangible And Inexplicable.

The Truth Isn't Always A Blinding Light. Sometimes It's A Deep And Dazzling Darkness, That Illuminates - And Burns - Just As Surely.
