Impact of Quantum Theory on Physics

A fundamental shift in our understanding of the physical world, replacing classical physics with a new set of rules governing energy, matter, and their interactions at the atomic and subatomic scales.

The introduction of quantum theory didn't demolish physics, but rather redefined its foundations, offering a new way of looking at the universe at the smallest level.

In the early 20th century, a new understanding of the physical universe emerged, moving beyond classical physics and embracing a new set of rules.

Quantum theory addresses the behavior of energy and matter at the smallest scales, dealing with atoms, electrons, and photons.

Max Planck, a pioneer in quantum theory, emphasized that this change was significant yet not destructive, rather a fundamental revision of physics.

A fundamental constant in physics that represents the smallest unit of energy that can be absorbed or emitted by an object. It is denoted by the letter 'h' and has a value of approximately 6.626 x 10^-34 joule-seconds.

A theory that describes the behavior of particles and energy at the atomic and subatomic levels. It developed from the work of Max Planck and other physicists. It explains phenomena like blackbody radiation and the photoelectric effect, and the quantization of energy.

A theoretical framework that combines quantum mechanics with special relativity. It is a theory of matter and energy, and it provides a description of the fundamental forces of nature.

A particle with the same mass and spin as its corresponding particle, but with an opposite charge. The electron's antiparticle is the positron. It was predicted by Paul Dirac.

Paul Dirac's equation, developed in 1928, is a relativistic wave equation that describes the behavior of spin-1/2 particles, such as electrons. This equation predicted the existence of antimatter particles.
