This theory introduces the idea that the laws of physics are the same for all observers moving at a constant speed, and that the speed of light is a universal constant. It famously led to the equation , showing that mass and energy are interchangeable.

These particles interact through four fundamental forces: Gravity , Electromagnetism , the Strong Nuclear Force (which holds nuclei together), and the Weak Nuclear Force (responsible for radioactive decay). 4. Wave-Function and Probability Introduction to the Basic Concepts of Modern Ph...

Modern physics seeks to categorize all known subatomic particles and the forces that govern them. This theory introduces the idea that the laws

Proposed by Werner Heisenberg, this principle states that it is impossible to know both the exact position and the exact momentum of a particle simultaneously. The more precisely we measure one, the less precisely we know the other. 2. Relativity: The Physics of High Speeds and Gravity The more precisely we measure one, the less

Energy is not a continuous flow but comes in discrete "packets" or chunks called quanta .

At the atomic level, nature behaves in ways that defy everyday intuition.
