Mathematical Physics

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate...

Physics, the fundamental science of matter and energy, encompasses all levels of nature from the subatomic to the cosmic, and underlies much of the technology around us. Understanding the physics of our universe is an essential aspect of humanity's quest to understand our environment and our place within it. Doing physics enables us to explore the interaction between environment and human society, and can help us to work towards the future sustainability of the planet.

What if numbers are not the building blocks of the universe—but reflections of the human mind? For over two thousand years, the Pythagorean vision has shaped our understanding of the cosmos: a universe ruled by harmony, order, and mathematical law. From the “music of the spheres” to modern physics, the idea that reality can be perfectly described by numbers has guided both science and philosophy. Yet as quantum mechanics, neuroscience, and information theory now suggest, this vision may be an exquisite illusion.
