The document provides an overview of physics as a natural science that studies matter, energy, and their interactions through space and time. It outlines the distinctions between natural and formal sciences, as well as various areas within physics such as classical mechanics, relativity, thermodynamics, optics, electromagnetism, and quantum mechanics. The text emphasizes the dynamic nature of the field and its ongoing quest to answer fundamental questions about the universe.

2. WELCOME TO THE WONDERFUL WORLD OF
PHYSICS!

3. TYPES OF SCIENCES
• NATURAL SCIENCES VS FORMAL SCIENCES.
• NATURAL SCIENCES – DESCRIBE AND PREDICT PHENOMENA IN REALITY. BASED ON EMPIRICAL EVIDENCE,
REPEATABILITY AND PEER REVIEW. CAN BE SPLIT IN TO LIFE SCIENCES AND PHYSICAL SCIENCES.
• FORMAL SCIENCES – LANGUAGE TOOLS THAT CHARACTERIZE ABSTRACT IDEAS AND STRUCTURES USING
SYMBOLIC SYSTEMS. MATH, LOGIC, DECISION THEORY, ETC… ALL FALL UNDER THIS CATEGORY.
• THE STUDY OF THE “NATURAL” WORLD.
• THE MOST FUNDAMENTAL NATURAL SCIENCE.
• STUDIES ENERGY, MATTER, MOTION, AND ITS EVOLUTION THROUGH SPACE AND TIME.

4. SO…WHAT EXACTLY IS PHYSICS?
• A NATURAL SCIENCE.
• STUDIES ALL FORMS OF MATTER WITH THE DESIRE TO UNDERSTAND AND PREDICT THEIR MOTION,
BEHAVIOR AND EVOLUTION THROUGH SPACE-TIME.
• THE OLDEST AND MOST FUNDAMENTAL NATURAL SCIENCE.
• DOESN’T HAVE CLEARLY DEFINED, RIGID BOUNDARIES BECAUSE OF ITS INTERSECTIONAL,
INTERDISCIPLINARY NATURE.

5. MAIN AREAS OF PHYSICS
• CLASSICAL MECHANICS – THE STUDY OF MACROSCOPIC OBJECTS. ANYTHING VISIBLE THAT’S NOT ON THE
ORDER OF AN ATOM.
• SPECIAL RELATIVITY – THE STUDY OF OBJECTS MOVING AT ANY SPEED.
• GENERAL RELATIVITY – THE STUDY OF GRAVITY.
• THERMODYNAMICS – THE STUDY OF HEAT, WORK AND ENTROPY.
• OPTICS – THE STUDY OF LIGHT.
• ELECTROMAGNETISM – THE STUDY OF ELECTRICITY AND MAGNETISM.
• QUANTUM MECHANICS/QUANTUM FIELD THEORY – THE STUDY OF THE VERY SMALL.

6. THE BEAUTY OF PHYSICS
• EXCITING FIELD FULL OF DRAMA, NEW DISCOVERIES AND THEORIES COMING OUT ON A YEARLY BASIS.
• TRIES TO ANSWER THE MOST FUNDAMENTAL QUESTIONS IN EXISTENCE.
• IT’S JUST COOL, OK?
