The reader is offered the famous course of lectures on general physics, which the outstanding American physicist, Nobel laureate Richard Feynman read at the California Institute of Technology. Feynman's lectures, recorded first on a tape recorder, and then "translated" into "written English" by M. professors Sands and R. Layton, not like any known course. They differ in the original method of presentation, which reflects the bright scientific individuality of the author, his point of view on the way of teaching physics students, his ability to infect readers with an interest in science. The sequence of presentation and the choice of material are also different from traditional. Lectures do not waste time explaining in "learned language" what the modern reader already knows or has heard. But they are fascinatingly told about how a person studies the surrounding nature, what position physics occupies in a number of other sciences, what problems science solves today and will solve tomorrow. Feynman's story vividly reflects the reasons that motivate the physicist to carry out the hard work of the researcher, as well as the doubts that he has when he faces difficulties that seem insurmountable. These lectures help not only to understand why it is interesting to do science, but also to feel how expensive victories get and how sometimes there are hard roads leading to them. The course will be useful to teachers, forcing them to take a fresh look at the process of teaching physics ; students who will find a lot of new in addition to what they learn in lectures; students who will form an interest in physics and help them enter modern science; As well as all those interested in physics.
