Quantum Mechanics

Philosopher Hilary Putnam talks about the challenge philosophers face in trying to interpret scientific functions --such as quantum mechanics-- when the effects are observable, but the function itself is not.

How Does Science Add to Knowledge?: Popper's 20th-century View of How Science Works

Inductivism remains the dominant view of how science works until the 20th century when Albert Einstein proposes a new approach to gravity. This and early work in quantum mechanics prompts philosopher Karl Popper to propose a radically new view of ho...

Scientific Theories and Realism

Philosopher Hilary Putnam argues that it is futile for philosophers of science to try to come up with a single, one-size-fits-all model that can be used to validate all scientific theories.

Is Time Real?: Would Newton and Einstein Have Agreed?

Not everyone agrees that relativity dismisses absolute time and therefore Newton's theories are accurate as far as they go. The way we measure time, however, has certainly been affected by 20th century physics, as in the so-called twins effect. Cont...

Is Time Real?: Scientific Theories of Time: Albert Einstein

In his first theory of relativity developed in 1905 Einstein came up with the idea that both space and time are relative to the state of motion of the observer. Time is not as absolute and universal as we thought;it can be changed by motion. Each ob...

Does Science Give Us Truth?: Quantum Mechanics Challenge to Theories of Truth: Einstein and the Realist View

The realist side of the quantum mechanics debate is headed by Albert Einstein, the most eminent scientist of the era. Einstein proposes that if quantum theory breaks down categories such as space and time we should look for a different set of concep...
