Modern physics is a branch of physics that developed in the early 20th century and onward or branches greatly influenced by early 20th century physics. Notable branches of modern physics include quantum mechanics, special relativity, and general relativity. Classical physics is typically concerned with everyday conditions: speeds are much lower ...
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
Modern physics began in 1900 with Max Planck’s discovery of the role of energy quantization in blackbody radiation, a revolutionary idea soon followed by Albert Einstein’s equally revolutionary theory of relativity and quantum theory of light. Kenneth Krane's Modern physics begins a text on quantum and relativity theories with a few pages ...
Quantum physics is a branch of modern physics in which energy and matter are described at their most fundamental level, that of energy quanta, elementary particles, and quantum fields. Quantum physics encompasses any discipline concerned with systems that exhibit notable quantum-mechanical effects, where waves have properties of particles, and ...
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.
For systemic use of experimentation in science and contributions to scientific method, physics and observational astronomy. The work of Principia by Newton, who also refined the scientific method, and who is widely regarded as the most important figure of the Scientific Revolution. [4] [5] Science (ancient) Thales (c. 624/623 – c. 548/545 BC ...
The field of physics is vast and can include such diverse studies as quantum mechanics and theoretical physics, applied physics and optics. Modern physics is becoming increasingly specialized, where researchers tend to focus on a particular area rather than being "universalists" like Isaac Newton, Albert Einstein, and Lev Landau, who worked in ...
Important modern branches of acoustics include ultrasonics, the study of sound waves of very high frequency beyond the range of human hearing; bioacoustics, the physics of animal calls and hearing, [38] and electroacoustics, the manipulation of audible sound waves using electronics. [39]
