Logical Positivism

A theory or statement is meaningful only if it can be verified or falsified through observation or experimentation.

Pragmatism

A philosophy that considers practical reasons, consequences, and real-world effects of meaning and truth.

Radioactivity

The process demonstrated by Henri Becquerel that involves nuclear decay and the concept of half-life.

Wright Brothers

Orville and Wilbur Wright who made long-distance flight more feasible and impacted warfare and transport during WW1 and WW2.

First Gasoline Automobile

Developed by John Frank and Charles Duryea, which won the first American car race.

Model T

Introduced by Henry Ford, it innovated mass production techniques in the automobile industry.

The Big Three

Ford, General Motors, and Chrysler dominated the automobile industry.

Quantum Mechanics

A branch of physics that deals with phenomena on a small scale, such as atoms and subatomic particles.

Heisenberg Principle

States that the more precisely the values of certain pairs of physical properties are known, the less precisely the values of the other properties can be known.

Antibiotics

Referred to as 'magic bullets' because they target disease without harming the host, as described by Paul Ehrlich.

Penicillin

Discovered by Alexander Fleming, it became the first effective drug for treating syphilis.

Radar

A detection system that uses electromagnetic waves.

Sonar

A detection system that uses acoustic waves.

Nuclear Fission

The process discovered by Otto Hahn, with the first reaction by Enrico Fermi, leading to nuclear power plants.

Alan Turing

Known as the father of modern computer science, he developed the Turing Machine.

The Manhattan Project

A large-scale government-funded project to harness nuclear energy and develop atomic bombs.

Big Bang Theory

A theory developed to explain the origin of the universe and the study of dark matter and dark energy.

General Relativity

Albert Einstein's theory that explains gravity and suggests the universe is expanding.

Hubble’s Law

Discovered by Edwin Hubble, it states that galaxies are moving away from us at speeds proportional to their distance.

Marie Curie

Known for her contributions to radioactivity, including the discovery of radium and polonium.

Albert Einstein

Famous for his theory of relativity and the equation E=mc².

Niels Bohr

Contributed to our understanding of atomic structure and quantum theory.

Ernest O. Lawrence

Known for his work in nuclear physics and the invention of the cyclotron, the first particle accelerator.
