Development of physics from Electromagnetics to Relativity.
  The development of physics from electromagnetics to relativity can be traced through several key milestones and discoveries. Here is a brief overview of the major steps in this journey:

1. Electromagnetic Theory (18th-19th century):
	* William Gilbert's (1544-1603) work on the magnetic compass and the concept of magnetism.
	* Hans Christian Oersted's (1777-1851) discovery of the electromagnetic relationship between magnetic fields and electric currents.
	* Michael Faraday's (1791-1867) work on electromagnetic induction, including the discovery of electromagnetic fields and the concept of electromagnetic induction.
	* James Clerk Maxwell's (1831-1879) formulation of the Maxwell's equations, which united the previously separate theories of electricity and magnetism into a single, coherent theory of electromagnetism.
2. Special Theory of Relativity (early 20th century):
	* Albert Einstein's (1879-1955) development of the special theory of relativity, which challenged the long-held belief that time and space are absolute.
	* The theory of special relativity introduced the concepts
The development of physics from electromagnetics to relativity marks a profound shift in our understanding of the physical universe. This transition, primarily occurring in the late 19th and early 20th centuries, involved the synthesis of concepts from electricity, magnetism, and the nature of space and time. Here’s an overview of that evolution:

### 1. **Foundations of Electromagnetism**
- **Early Discoveries**: The groundwork for electromagnetism began with the work of scientists like Hans Christian Ørsted, who discovered that electric currents create magnetic fields (1820), and André-Marie Ampère, who formulated Ampère's law.
- **James Clerk Maxwell**: The most significant development came with Maxwell's equations (published in the 1860s). These four equations unified electricity and magnetism into a single framework, describing how electric and magnetic fields propagate and interact with charges. Maxwell's work predicted the existence of electromagnetic waves, which travel at the speed of light.

### 2. **The Nature of Light**
- **Wave-Particle Duality**: Maxwell's equations suggested that light is an electromagnetic wave. However, the nature of light remained a topic of debate, with some experiments suggesting it also has particle-like properties.
- **Experiments**: The famous Michelson-Morley experiment (1887) sought to detect the "aether," a medium through which light waves were thought to propagate. The null result of this experiment challenged existing notions of
