Summary
This study updates citation databases for top-cited scientists globally. It includes detailed, diverse indicators for a comprehensive view of scientific impact.
Area of Science:
- Bibliometrics and Scientometrics
- Scientific Impact Assessment
- Research Evaluation
Background:
- Citation databases are crucial for tracking scientific influence.
- Previous assessments often lacked granular data on diverse indicators.
- An updated, comprehensive view of top scientists is needed.
Purpose of the Study:
- To present an updated analysis of top-cited scientists.
- To incorporate more granular and diverse indicators of scientific achievement.
- To provide a more nuanced understanding of research impact.
Main Methods:
- Analysis of citation data from major scientific databases.
- Inclusion of multiple bibliometric and non-bibliometric indicators.
- Comparative assessment across various scientific disciplines.
Main Results:
- Identification of leading scientists based on updated metrics.
- Demonstration of the value of diverse indicators in ranking.
- Highlighting trends in scientific productivity and influence.
Conclusions:
- Updated citation databases offer a more robust evaluation of scientific contributions.
- Diverse indicators provide a richer picture of a scientist's impact.
- This work refines the assessment of top-cited researchers worldwide.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

01:09Empirical Method to Interpret Standard Deviation
8.3K
The empirical rule, also known as the three-sigma rule, allows a statistician to interpret the standard deviation in a normally distributed dataset. The rule states that 68% of the data lies within one standard deviation from the mean, 95% lies within two standard deviations from the mean, and 99.7% lies within three standard deviations from the mean. Additionally, this rule is also called the 68-95-99.7 rule.
This rule is used widely in statistics to calculate the proportion of data values...

02:40The Scientific Method
64.3K
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.

01:32The Scientific Method
254.5K
The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

01:11Statistical Analysis: Overview
12.9K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

01:50Statistical Significance
20.8K
Once data is collected from both the experimental and the control groups, a statistical analysis is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful). In psychology, group differences are considered meaningful, or significant, if the odds that these differences occurred by chance alone are 5 percent or less. Stated another way, if we repeated this...
