Summary
Wikipedia
Area of Science:
- Analysis of scientific literature consumption and citation patterns within Wikipedia.
- Focus on identifying key scientific journals and disciplines cited.
- Exploration of scientific literature obsolescence using the Price index.
Background:
- Wikipedia serves as a significant platform for accessing scientific information.
- Understanding how scientific knowledge is represented and utilized on Wikipedia is crucial.
- Previous research has not comprehensively analyzed Wikipedia's scientific referencing landscape.
Purpose of the Study:
- To analyze how Wikipedia editors reference scientific papers.
- To identify the most relevant scientific journals and categories cited on Wikipedia.
- To investigate the consumption and obsolescence of scientific literature through Wikipedia.
Main Methods:
- Adapted co-citation analysis to create Pathfinder networks (PFNET).
- Utilized reference data from Altmetric.com and CiteScore Metrics.
- Analyzed 847,512 references from 193,802 Wikipedia articles to 598,746 scientific articles.
Main Results:
- "Medicine" and "Biochemistry, Genetics and Molecular Biology" are highly cited fields.
- Multidisciplinary journals and high-impact factor journals dominate citations.
- Only 13.44% of Wikipedia citations are to Open Access journals.
Conclusions:
- Wikipedia's scientific content reflects a strong emphasis on medical and biological sciences.
- Citation practices favor established, high-impact, and multidisciplinary journals.
- Limited citation of Open Access journals suggests potential barriers or preferences in Wikipedia's referencing ecosystem.

02:40The Scientific Method
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.
02:18Network Covalent Solids
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

02:39Entropy
Salt particles that have dissolved in water never spontaneously come back together in solution to reform solid particles. Moreover, a gas that has expanded in a vacuum remains dispersed and never spontaneously reassembles. The unidirectional nature of these phenomena is the result of a thermodynamic state function called entropy (S). Entropy is the measure of the extent to which the energy is dispersed throughout a system, or in other words, it is proportional to the degree of disorder of a...
02:26Protein Networks
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:17Open and closed-loop control systems
Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal and...
