Here's some information about Karl Popper, formatted as requested:

Sir Karl Raimund Popper (1902-1994) was an Austrian-British philosopher, academic and social commentator. He is generally regarded as one of the 20th century's most influential philosophers of science.

• Philosophy of Science: Popper is best known for his rejection of the classical inductivist views on the scientific method, in favor of <a href="https://www.wikiwhat.page/kavramlar/falsificationism">falsificationism</a>. He argued that scientific theories cannot be proven, but they can be falsified, and that this is the defining characteristic of empirical science. A theory should be considered scientific only if it is testable and conceivably proven false.

• Open Society: Popper also made significant contributions to social and political philosophy, most notably in The Open Society and Its Enemies. In this work, he defends <a href="https://www.wikiwhat.page/kavramlar/open%20society">open society</a> principles and criticizes forms of historicism and totalitarianism, which he saw as based on flawed philosophical assumptions.

• Critical Rationalism: Another core concept in Popper's philosophy is <a href="https://www.wikiwhat.page/kavramlar/critical%20rationalism">critical rationalism</a>. This is the view that knowledge grows through a process of conjecture and refutation. We should put forward bold conjectures and then subject them to rigorous testing, being ready to abandon them if they are falsified.

• The Problem of Demarcation: Popper's work addresses the <a href="https://www.wikiwhat.page/kavramlar/problem%20of%20demarcation">problem of demarcation</a>, which is the question of how to distinguish between science and non-science (including pseudo-science). His proposed solution is falsifiability.
