Physicist Facts for Kids

Albert Einstein, a key theoretical physicist who developed the theory of relativity and parts of early quantum theory.

In an 18th-century experiment in "natural philosophy" (later to be called "physics") English scientist Francis Hauksbee works with an early electrostatic generator.

A physicist is a scientist who studies physics. Physics is all about how the universe works. It looks at how matter (everything around us) and energy interact. Physicists try to understand everything from tiny sub-atomic particles to the entire universe.

Physicists are curious about why things happen. They often use mathematics to explain their ideas. There are two main types of physicists:

Experimental physicists do experiments and observe what happens. They collect data and analyze it.
Theoretical physicists use math and logic to create models. These models help explain why things happen and predict what might happen next.

Physicists also use their knowledge to solve real-world problems. They can develop new technologies. This is sometimes called applied physics or engineering physics.

What Do Physicists Study?

Physicists explore many different areas. They study things that are very, very small and things that are incredibly huge.

The Very Small

Particle physics: This field looks at the smallest building blocks of the universe. These are particles like quarks and leptons.
Quantum physics: This area studies how energy and matter behave at the atomic and sub-atomic levels. It's a bit strange, but it helps us understand things like lasers and computer chips.

Everyday Physics

Mechanics: This is about how objects move and the forces that make them move. Think about throwing a ball or how a car works.
Thermodynamics: This studies heat and temperature. It explains how engines work or why ice melts.
Electromagnetism: This field looks at electricity and magnetism. It helps us understand light, radio waves, and how motors work.

The Very Big

Astrophysics: This is the study of stars, planets, galaxies, and other objects in space.
Cosmology: This field tries to understand the origin, evolution, and future of the entire universe.
