**Prerequisites**- Completion of the subject F1030 Mechanics and molecular physics or corresponding knowledge.
**Course Enrolment Limitations**- The course is also offered to the students of the fields other than those the course is directly associated with.
**fields of study / plans the course is directly associated with**- Physics (programme PřF, M-FY)

**Course objectives**- The aim of the course is

(1) to recapitulate concepts and laws of newtonian physics;

(2) to get insight into statistical physics through the thermodynamics theorems and methods of working up physical measurements.

Much attention is paid to thinkable misconceptions and to possible misinterpretations of thermodynamics theorems.

Historical notes and actual remarks are organic parts of the course. **Syllabus**- 1. Often misconceptions in understanding of Newton's laws of motion.
- (1) First law – Axiom. (2) Definition – Natural law. (3) Causality – Interaction.
- 2. Methodology of building physical concepts.
- Acmotionation (etymology: celerity–acceleration, motion–acmotionation). Inertial mass. Force. Gravitational mass. Kinetic energy of the particle. Potential energy of the system.
- 3. Dot and vector products of vector quantities.
- Distance-changeability of the particle. Work on the particle.
- Virial.
- Moment analogy of the second axiom.
- Kepler's second law.
- 4. Concepts and laws of newtonian mechanics.
- Static and kinetic state characteristics. Process characteristics.
- Laws of motion. Conservation laws. First theorem of thermodynamics.
- 5. Atoms and their aggregations.
- Ideal. gas. Real gas. Experimental gas laws
- Size of molecules. Avogadro – Loschmidt – Kekulé – Einstein.
- Thermal energy.
- Two-atomic model of condensed matter. Bonding energy.
- 6. Structure of bodies
- Crystal structure of Po; Fe, W; Al, Ni, Cu, Ag, Au, Pt; C, Ge, Si; Co.
- Structure types NaCl, Al-Ni, austenit.
- Interatomic distances. Size of atoms.
- 'Aperiodic crystal'. Macromolecules. Izomerics. Structure of DNA.
- 7. Physical measurements.
- Probability intervals. Precision. Accuracy.
- 8. Temperature. Heat.
- Macroscopic characteristics of temperature.
- Microstructure definition of temperature.
- Determination of atom vibration frequency from room temperature.
- Building up the concept heat.
- 9. Statistical relations.
- Isotropy of space. Homogeneity of space and time. Irreversibility of time.
- Virial theorem.
- Equipartition principle. Ergodic hypothesis – postulate of statistical physics.
- 10. The second theorem of thermodynamics.
- Disorder spontaneous increase. Order out of chaos.
- Temperature – Heat – Entropy.
- 11. What is life?
- Physical law in biology.
- Schrödinger's ideas. Contents of his book 'What Is Life?'.
- 12. Closing discussion with students' and lecturer's proposals concerning the course contents and style of teaching and learning.
- LITERATURE
- The needed background is given in student's acquaintance with any secondary school and university physics textbook used by him/her.
- During the classes the student obtains printed aids: (1) Facsimilia of selected pages from uneasily accessible literature. (2) Czech translations of the facsimilia if they are in Latin or in German. (3) Sheets to special topics.
