Students in some international schools (Macau Anglican College, School of Nations, and Generations International School) can take the Cambridge exam board, as well as the Edexcel exam board at their schools (Pui Ching Middle School (Coloane ...
The term Modern physics is normally used for fields which rely heavily on quantum theory, including quantum mechanics, atomic physics, nuclear physics, particle physics and condensed matter physics. General and special relativity are usually considered to be part of modern physics as well.
Physics (Greek: physis–φύσις meaning "nature") is the natural science which examines basic concepts such as mass, charge, matter [1] and its motion and all that derives from these, such as energy, force and spacetime. [2] More broadly, it is the general analysis of nature, conducted in order to understand how the world and universe ...
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
Aristotelian physics is the form of natural philosophy described in the works of the Greek philosopher Aristotle (384–322 BC). In his work Physics, Aristotle intended to establish general principles of change that govern all natural bodies, both living and inanimate, celestial and terrestrial – including all motion, quantitative change, qualitative change, and substantial change.
In expository writing, a topic sentence is a sentence that summarizes the main idea of a paragraph. [1] [2] It is usually the first sentence in a paragraph. Also known as a focus sentence, a topic sentence encapsulates or organizes an entire paragraph. Although topic sentences may appear anywhere in a paragraph, in academic essays they often ...
1. First postulate (principle of relativity) The laws of physics take the same form in all inertial frames of reference.. 2. Second postulate (invariance of c) . As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body.
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the behavioural sciences (e.g., economics, psychology, and sociology ...
