In response to the most important scientific questions about the origin of the world and the Earth, a popular science book has been created. The first chapter will take the reader into an amazing world of small particles, from electrons, protons, neutrons, quarks, antiparticles to the Higgs boson; deals with the theory of the origin of space. The second chapter looks at how many elements are found in nature and how much can man create? Why are the elements radioactive? The third chapter looks at the new states of matter, including the supercold condensates at low temperatures, which are only a few billionths of a kelvin above absolute zero. Nanotechnologies and optical tweezers have also been studied. The fourth chapter is devoted to the Earth. It turns out that there are both asphalt lakes and a natural nuclear reactor on Earth. Particular attention is paid to the unquenchable curiosity of science heroes, risking their lives to rise high above the clouds - in the stratosphere. The fifth chapter is dedicated to one of the most important discoveries in physics of the 20th century - the discovery of nuclear energy.
