In physics, the observer effect is the disturbance of an observed system by the act of observation. [1] [2] This is often the result of utilising instruments that, by necessity, alter the state of what they measure in some manner. A common example is checking the pressure in an automobile tire, which causes some of the air to escape, thereby ...
Experimental physics is the category of disciplines and sub-disciplines in the field of physics that are concerned with the observation of physical phenomena and experiments. Methods vary from discipline to discipline, from simple experiments and observations, such as Galileo's experiments , to more complicated ones, such as the Large Hadron ...
The Chemistry, Biology, Physics and Design Technology was last updated for first teaching in September 2014, with syllabus updates (including a decrease in the number of options), a new internal assessment component similar to that of the Group 5 (mathematics) explorations, and "a new concept-based approach" dubbed "the nature of science". A ...
Chien-Shiung Wu, after whom the Wu experiment is named, designed the experiment and led the team that carried out the test of the conservation of parity in 1956.. The Wu experiment was a particle and nuclear physics experiment conducted in 1956 by the Chinese American physicist Chien-Shiung Wu in collaboration with the Low Temperature Group of the US National Bureau of Standards.

astrophysics, the physics in the universe, including the properties and interactions of celestial bodies in astronomy; atmospheric physics is the application of physics to the study of the atmosphere; space physics is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System
After completing a set of five prerequisite courses, students must take additional courses in quantum mechanics, thermodynamics, experimental physics, and complex analysis. [5] Physics concentrators are required to complete a junior paper as a preliminary investigation into a senior thesis topic.
[3] [4] In 1964, John Stewart Bell proposed his famous theorem, which states that no physical theory of hidden local variables can ever reproduce all the predictions of quantum mechanics. Implicit in the theorem is the proposition that the determinism of classical physics is fundamentally incapable of describing quantum mechanics.
The Berkeley course was contemporary with The Feynman Lectures on Physics (a college course at a similar mathematical level), and PSSC Physics (a high school introductory course). These physics courses were all developed in the atmosphere of urgency about science education created in the West by Sputnik .
