Picha na vitu vinatembeaje? Ni kwa vipi wanyama wanatembea? Mwendo ni nini?

Upinde wa mvua unajitengenezaje? Je, kujiinulisha kunawezekana? Je, mashine za wakati zipo? Je, "kwanta" ina maana gani? Ni kiasi gani kikubwa cha nguvu kina patikana katika nature(asili)? 'Sehemu tupu' ni kweli tupu? Je, dunia ni seti? Je, ni matatizo yapi ya sayansi ya fizikia ambayo bado hayajatatuliwa?

This site publishes a free physics textbook that tells the story of how it became possible, after 2500 years of exploration, to answer such questions. The book is written to be entertaining, surprising and challenging on every page. With little mathematics, the text explores the most fascinating parts of mechanics, thermodynamics, special and general relativity, electrodynamics, quantum theory and modern attempts at unification. The essence of these fields is summarized in the most simple terms: it is shown how they are based on the notions of minimum entropy, maximum speed, maximum force, minimum change of charge and minimum action.

The text explores the limits of time and space, and the wonders that can be discovered there. Written in English, its over 1300 pages are provided for students, teachers, and for anybody who is interested in the precise description of nature.

For each field of physics, the latest research results, the best images, the most interesting physical puzzles and the most telling physical curiosities are presented. More than 1600 challenges and over 500 illustrations and tables are included.
