The picture of the world in modern physics is a dizzying, interesting and complex topic. What is the fabric of our reality made of? What fundamental forces govern it? How far are we from creating a unified theory that can explain everything? Dmitry Kazakov, Director of the Laboratory of Theoretical Physics at the Institute for Nuclear Research and Corresponding Member of the Russian Academy of Sciences, knows how to talk about the most complex things in the most accessible way. What is the concept of the beauty of string theory? How does it work in the modern context? Does the world have eleven spatial dimensions? Could Einstein and Landau have liked string theory? What is the significance of symmetry in physics? Does the world contain antimatter? What do the biblical story of the expulsion from paradise and the picture of the world have in common? Is it possible to see dark matter and feel dark energy? Why do elementary particles have poetic names? And when will the factory of charm start working in Russia?
