A handwritten, signed letter by Albert Einstein is among the top lots in RR Auction's current sale, which closes later today.
Bidding on the lot, which dates to 1925, stands at $55,542.
It's written in Italian to engineer Giovanni Giorgi, and offers an incredible insight into Einstein's thoughts on God and relativity.
He writes: "I agree with your opinion on the fact that the movement of an ether with a [mathematical expression] so high is particularly impossible. God created the world with more intelligence and elegance. You right to compare with Miller's works, the laws of aberration.
"The theory of Stokes-Planck is very artificial and can not—in my opinion—explain this law of aberration. I would be very curious to know the real cause of the Miller's phenomenon. I do not doubt the validity of the theory of relativity."
The auction house comments: "Each and every sentence contains a revelatory turn and could be expounded upon at length within the context of Einstein's life and work.
"Although he did not believe in a personal deity, Einstein was not averse to speaking of God in a scientific context when discussing differing interpretations of quantum physics."
Another Einstein letter, expounding on his belief that faith in God is "childish", sold for $404,000 in 2004.
