The curriculum for Physics IBDP is designed in such a way to bring students and readers alike to the frontiers of modern science and arouse the spirit of scientific inquiry in their minds. The topics in the syllabus range from the ancient science of the Greeks to modern disciplines like Atomic and Astrophysics, which makes the students aware of the entire spectrum of the discoveries and advances in Physics as well as the rationale and need behind them. As such the chapters are divided by classical and modern distinctions: Newtonian Mechanics describe the original theories of motion and movement, Thermodynamics talk about our original assumptions of ideal gas and principles of heat and temperature, while Electrodynamics cover the interconnected universe of electricity, magnetism and electromagnetic waves, and the various properties and phenomena associated with them.

In contrast lies the topics of Modern Science, ranging from Atomic, Nuclear and Particle Physics to the more advanced study of motion in Einstein’s Relativity and Quantum Mechanics. A complete understanding of these topics will render any reader with the amazing ability to apply Physics to every corner of life, ranging from the mundane to the extraordinary; as well as assuredly prepare them not only for a future in an advanced scientific discipline, but also in fields like Economics, Finance and Technology, all of which require a scientific mindset at their core. 

In this chapter of Measurements and Uncertainties, we understand how the SI system of units is defined and formulated, and the basis of the seven fundamental units from which all other units are derived. We also talk about orders of magnitudes of various units, and how to express numbers in scientific notations using significant figures.

Further we discuss random and systematic errors, the difference between them, and how to quantify and operate on such uncertainties while quoting the results of our experiments. Finally, we introduce the concept of scalar and vector quantities, their examples and uses, and how to operate algebraically on both quantities in relation to physical systems.
