[1] Scientific knowledge must be grounded in observable phenomena and must be capable of being verified by other researchers working under the same conditions. [2] Natural, social, and formal science make up the fundamental sciences, which form the basis of interdisciplinarity - and applied sciences such as engineering and medicine.
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 social sciences (e.g., economics, psychology, and sociology), which ...
A practitioner of science is called a "scientist". Modern science respects objective logical reasoning, and follows a set of core procedures or rules to determine the nature and underlying natural laws of all things, with a scope encompassing the entire universe. These procedures, or rules, are known as the scientific method.
The Cornell Notes system (also Cornell note-taking system, Cornell method, or Cornell way) is a note-taking system devised in the 1950s by Walter Pauk, an education professor at Cornell University. Pauk advocated its use in his best-selling book How to Study in College . [ 1 ]
A branch of science (a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe). [1] [2] [3] A branch of natural science – natural science is a major branch of science that tries to explain and predict nature's phenomena, based on empirical evidence.
Quarks are massive particles of spin-1 ⁄ 2, implying that they are fermions. They carry an electric charge of − 1 ⁄ 3 e (down-type quarks) or + 2 ⁄ 3 e (up-type quarks). For comparison, an electron has a charge of −1 e. They also carry colour charge, which is the equivalent of the electric charge for the strong interaction.

Humans no longer had to spend all their time working for survival, enabling the first specialized occupations (e.g. craftsmen, merchants, priests, etc.). Curiosity and education drove the pursuit of knowledge and wisdom, and various disciplines, including science (in a primitive form), arose. This in turn led to the emergence of increasingly ...
