Israel's national library is making the writings of Sir Isaac Newton available online to people worldwide.
The library has digitized some 7,500 handwritten pages of Newton's theological collection. Newton is often considered a great scientist.
But Milka Levy-Rubin, a curator at Israel's national library, points out that Newton was also a devout Christian, who wrote far more about theology than physics.
"Today, we tend to make a distinction between science and faith, but to Newton it was all part of the same world," Levy-Rubin said.
"He believed that careful study of holy texts was a type of science that if analyzed correctly could predict what was to come," she said.
"As far as Newton was concerned, his approach was that history was as much a science as physics. His world view was that his 'lab' for understanding history was the holy books," she said. "His faith was no less important to him than his science."
