Summary
A new database of 100,000 top scientists offers standardized citation metrics, including h-index and coauthorship-adjusted hm-index. This resource provides career-long and single-year impact data across 22 scientific fields.
Area of Science:
- Covers 22 major scientific fields and 176 subfields.
- Includes comprehensive data for top-cited scientists globally.
Background:
- Citation metrics are essential but often misused in research evaluation.
- Standardized metrics are needed for accurate assessment of scientific impact.
Purpose of the Study:
- To create a publicly available, standardized database of top scientists' citation metrics.
- To provide a comprehensive resource for evaluating scientific impact and career progression.
Main Methods:
- Compiled data for 100,000 top scientists.
- Calculated metrics including citations, h-index, and coauthorship-adjusted hm-index.
- Included data on self-citations and authorship positions, with career-long and single-year impact.
Main Results:
- Database provides standardized citation data, field- and subfield-specific percentiles.
- Includes metrics adjusted for coauthorship and authorship position.
- Offers data updated to end of 2017 and 2018 for comparative analysis.
Conclusions:
- The database offers a valuable, standardized tool for assessing scientific contributions.
- Facilitates more accurate and equitable evaluation of researchers across diverse fields.
- Aims to mitigate misuse of citation metrics in academic assessment.

02:20Milgram's Obedience to Authority
7.2K
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”

03:50The Scientific Method
65.1K
Chemistry is an empirical science. Scientists often pose questions to understand the chemistry in everyday life and seek answers to these questions. To achieve this, scientists follow a definitive series of steps that together make up the Scientific Method. This approach involves making observations, asking questions, building a hypothesis, conducting experiments, analyzing results, and forming a conclusion.

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...

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.

20.6K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
