The story of quantum entanglement, perhaps the strangest concept in science. Mind-bending concepts and brilliant experiments lead us to a profound new understanding of reality.

As Albert Einstein lay on his deathbed, he asked only for his glasses, his writing implements and his latest equations. He knew he was dying, yet he continued his work. In those final hours of his life, while fading in and out of consciousness, he was working on what he hoped would be his greatest work of all. It was a project of monumental complexity. It was a project that he hoped would unlock the mind of God.
