A prismatic look at the meeting of Marie Curie and Albert Einstein and the impact these two pillars of science had on the world of physics, which was in turmoil. In 1911, some of the greatest minds in science convened at the First Solvay Conference in Physics. Almost half of the attendees had won or would go on to win the Nobel Prize. Over the course of those few days, these minds began to realise that classical physics was about to give way to quantum theory, a seismic shift in our history and how we understand not just our world, but the universe. At the centre of this meeting were Marie Curie and a young Albert Einstein. In the years preceding, Curie had faced the death of her husband. She was on the cusp of being awarded her second Nobel Prize, but scandal erupted all around her when the French press revealed that she was having an affair with a fellow scientist, Paul Langevin. The subject of vicious misogynist and xenophobic attacks in the French press, Curie found herself in a storm that threatened her scientific legacy. Albert Einstein proved a supporter in her travails. He was young and already showing flourishes of his enormous genius. Curie had been responsible for one of the greatest discoveries in modern science. Utilising never before seen correspondence and notes, Jeffrey Orens reveals the human side of these brilliant scientists, one who pushed boundaries and demanded equality in a man's world, no matter the cost, and the other, who was destined to become synonymous with genius.
