The book is intended as a general background, after which the student can read texts that deal with semiconductors, dielectrics or magnetic materials in more detail.
The book also contains elements for understanding the quantum Hall effect and the Josephson effect, two effects important in precise measurements, measuring standards, and the development of computers.
The textbook Arithmetic by Dr. Franjo Hočevar, which served as the basic teaching material for upper secondary school grades in the first half of the 20th century, includes key arithmetic concepts adapted to the educational curriculum of the time.
