In 1885, Planck predicted that the definition "energy is the ability to do work" would cease to be valid in twenty years, as it is not consistent with the 2nd Law of Thermodynamics. Approximately one hundred and forty years have passed since then, and this definition still remains the most common definition of energy, despite the fact that, during the last fifty years, many publications in renowned physics education journals frequently raise the issue of its inconsistency with the 2nd Law of Thermodynamics.

Similarly, Newton, in 1687, in his famous work Philosophiae Naturalis Principia Mathematica, showed that pressure makes sense only in fluids and concluded with the relations of hydrostatics and the interpretation of the hydrostatic paradox, using the definition he provided for fluids and his 3rd Law. However, his work seems to be ignored even today, as pressure is introduced in educational books with examples from solids.

The above are two of what the author calls "original sins of physics books." In the book, the author critically examines some of the most prevalent "original sins" in physics education. Eight out of the ten chapters of the book focus on such recurring mistakes and misunderstandings that appear internationally in physics books.

The remaining two chapters address significant questions that are often omitted from the curriculum, such as: "What corresponds at the microscopic level to the potential difference between two points in an electrical circuit?" The inspiration for many parts of the book came from questions posed by students, university students, or educators, and from issues that arose during preparation for teaching.

The goal of the book is to contribute to the creation of reflection and the initiation of discussions that may lead to changes in school physics books. One such example is the discussion that took place in a network of educators, which ultimately led to the removal of paragraphs and exercises from the curriculum of the 3rd grade of high school, which incorrectly referred to Bernoulli's Law.
