Physics. Schrödinger Grew Up, but the Questions Remain

What is radiation? What is required to “assemble” the Universe? Who will age faster— a person on Earth or someone flying to another planet? Answers to these and many other fascinating questions can be found in the book by a Candidate of Physical and Mathematical Sciences.

Alla Borisovna Kazantseva is a Candidate of Physical and Mathematical Sciences, an Associate Professor at the Department of General and Experimental Physics of the Moscow Pedagogical State University (MPGU), and a finalist in RAS competitions in 2019 and 2021 for the best science popularization works. Physics is one of the key sciences that has made the world what we know it to be: cars and trains, rockets and orbital stations, television and the internet, electronic microscopes, mobile communications, and other achievements of technical civilization.

Physics helps to make sense of a wide range of phenomena. What is “noise pollution,” and why do some sounds harm the body while others can help in recovery? Who ages faster—a native of Earth or an astronaut on an interplanetary flight? Where does the radiation that is everywhere come from, and how does it affect us? What colors need to be mixed to get white? What “ingredients” are needed for the birth of the Universe: ordinary and dark matter, dark energy—and what else?

Physics not only poses exciting questions, but also provides accurate, evidence-based answers. Skeptical? Then try to estimate which is greater: the number of stars in the observable Universe, the number of grains of sand on Earth’s beaches, or the number of molecules in a glass of water. The solutions to these and many other problems await you on the pages of the book.
