The series of four richly illustrated books starts with the basics of measurements, gravitation, temperature, magnetism, vacuum and pressure, which could be applied to the engineering, ship-building, machine building and military, and continues through more complicated physics equations and experiments in the second volume. The third volume is dedicated to optics and the fourth to magnetism and electricity, making this book one of the earliest Ottoam publications on the latter subject.
The authors of this extensive work were Abdüllatif Efendi (Mülazım, meaning junior officer), teacher at Darüşşafaka Society, the first non-governmental organization in the Ottoman Empire and at the Military Academy, and a teacher of physics at Darüşşafaka, Hasan Fethi.
