A Fórmula de Deus  A Fórmula de Deus (God's Formula), in English "The Einstein Enigma", is the fourth novel written by the Portuguese journalist and writer José Rodrigues dos Santos, published in 2006 in Portugal. It was the best-selling novel in Portugal in 2006, selling 100,000 copies. The novel narrates a quest for the scientific proof of the existence of god by a Portuguese professor, Tomás Noronha, based on a formula developed by Albert Einstein himself. The adventure takes place in Iran, Tibet and Portugal, with the involvement of the CIA. The book presents an innovative view about the origins of the universe, based on recent physics theories. It is the spring of 1951. Just off a small street in Princeton, NJ, an unidentified man stands hidden, carefully monitoring an unfolding scene. A police-escorted motorcade stops at a small, unremarkable house while an old man with a shock of white hair jumps out of the lead car. As he ambles up the walkway, a man of around the same age—also sporting wild white hair—descends from the porch and warmly greets him. The observer lurking in the shadows is CIA — fellow operatives are also close by, recording the conversation taking place inside the house between newly arrived Israeli Prime Minister David Ben-Gurion and his host, the word-renowned scientist Albert Einstein. The subject of their conversation: nuclear weapons and the existence of God. World-famous cryptanalyst Tomás Noronha is waiting on the front steps of the Egyptian Museum in Cairo when an attractive, dark-haired woman approaches and invites him to lunch in the Moslem quarter. Her name is Ariana Pakravan. She is Iranian and during the course of their lunch hires Tomás to decipher a cryptogram hidden in an unknown document that has been recently discovered in Iran and is at present being kept under heavy security in Tehran. The document turns out to be a manuscript written by Albert Einstein, and its content may prove so extraordinary that it's likely to shake the world. The manuscript's title is, simply, Die Gottesformel. The Einstein Enigma. Before Tomás leaves for Tehran, however, the American cultural attaché in Lisbon invites him for a meeting at the US Embassy. There, the cryptanalyst meets with two CIA operatives who warn him that the manuscript in question is in fact Einstein's recipe for an easily produced atomic bomb, commissioned many years ago by Israeli Prime Minister David Ben-Gurion.
